TELECOMMUNICATIONS –PHASE 1

The following telecommunication providers advised that they would not be affected by the proposal. EU networks, Neos, ESP

N1 FOUL DRAINAGE

All foul water drainage from the proposed development will drop to the below ground drainage network. This network will be routed to the external courtyard and access road, and then outfall via a new 100mm diameter gravity connection to the 600mm diameter Thames Water foul sewer to the North of the site, via a demarcation manhole. This connection is subject to an S106 agreement with Thames Water. Non-return/flap valves are to be located in an accessible location within the network to protect against sewer surcharge.

A pre-development enquiry has been submitted as part of the wider Masterplan proposals, to confirm capacity within the public sewer network for the proposed foul flows.

There are no proposed alterations to the drainage network serving the existing retail units being retained in the north-east part of the site.

N2 FOUL DRAINAGE

Foul water flows from plot N2 will be collected at a high level and be conveyed to the boundaries of the building, before connecting to the manholes located in the external pavement area via soil vent pipes. It will then connect to the wider WSP proposed masterplan foul network and discharge to the existing 600mm diameter Thames Water foul sewer located to the south of Rennell Street, via the proposed manhole.

N2 SURFACE WATER DRAINAGE

Sitewide flood risk assessment and surface water drainage strategies is produced by Expedition. N2 surface water drainage strategy has been developed to align with it.

Roof area from the southwest corner of the plot will be picked up by rain water pipe and to be connected to Expedition masterplan podium surface water network.

Roof area from the rest of the plot will be picked up by rain water pipes and to be connected to Expedition masterplan underground surface water network which will discharge to the existing 229mm diameter Thames Water surface water sewer located to the south of Rennell Street, via proposed manhole.

Type C non-infiltration permeable paving is proposed for the external area, with fin drain proposed at the subbase to collect the runoff and connect to the N2 surface water network.

Sustainable drainage systems (SuDS) will be integrated with the masterplan surface water drainage network which will incorporate attenuation systems and rain gardens.

Attenuation volume for N2 will be provided within the attenuation tank located between plot N1 and N3. It has been sized to accommodate the 1 in 100-year storm event including an allowance of 40% for predicted climate change. As part of the sitewide drainage network, the runoff would be restricted to greenfield rates before discharging to the Thames Water sewer. Refer to Expedition masterplan drainage design for details.

A surface/foul water pre-developmentenquiryhasbeen made to TWto understand if there isadequate capacity to cater the Proposed Development. At the time of writing this report, WSP are still in the progress of liaising with Thames Water

1 INTRODUCTION

This Utility Statement has been produced on behalf of Landsec Lewisham Limited to assist with the delivery of the development proposed Lewisham Shopping Centre.

The proposed development consists of a Hybrid planning application for the demolition and comprehensive, phased redevelopment of land at Lewisham Shopping Centre and adjacent land, comprising living uses, including residential, co-living and student accommodation, town centre uses as well as community and cultural uses.

The local authority is Lewisham Borough Council.

Figure 1 – Location Plan

This report reviews the existing utility networks to understand:

▪ Extent of likely utility constraints

▪ The ability of the existing electricity, potable water, and telecommunications network to support the anticipated utility loads.

2 UTILITY STRATEGY

Utility network records have been used as the basis of ongoing consultation between WSP and utility stakeholders to identify proposed points of connection to accommodate the project proposals.

Records showing the distribution of private services within the site i.e. private networks, are unavailable to the design team.

WSP has undertaken an assessment of the load profile to predict the anticipated utility demands for the site.

Based on the anticipated loads, enquires have been issued to the incumbent electricity providers to assess the impact of the demands on their existing networks and/or reinforcement works to accommodate the proposals.

The required on-site infrastructure will be supplied from the existing networks surrounding the site and with the infrastructure and service connections distributed to and around the site below ground and arranged in accordance with Street Works UK (NJUG) guidelines. WSP has developed a utility strategy which indicates Points of Connection and an incoming services strategy

2.1 EXISTING UTILITIES

WSP has obtained utility record information for statutory undertakers known to be operating in the area of the site (Centara Desktop Utility Search Ref: CEN21191 Dated 8th September 2021).

Table 2 – Utility Loading Summary

supply (life safety)

ELECTRICITY

UK Power Networks is the Electricity Distribution Network Operator (DNO) for the site.

WSP has approached the incumbent utility provider to determine points of connection and any-off site reinforcement, or upgrade works required to supply the proposed development.

Table 3 – Electrical Load Assessment

confirmed as being from separate primary substation to main supply

We understand, of the 14 affected UKPN substations on the LSC development site, 7 of these are dedicated substations servicing LSC (substation numbers 81157, 81152, 80164 x 2, 81159, 81033 and 81148), with the remaining 7 substations being network substations servicing loads outside the development (81150, 81158, 81149, 81147, 81770, 81093 and 80387).

Of the three substations in Phase 1a, two are dedicated substations (81159 Riverdale Road R/O 66 and 81033 Molesworth Street Littlewoods) and one is a network substation, (81147 Lewisham High Street Woolworths)

WSP approached UK Power Networks on the 7TH March 2024 to request a budget estimate for a supply of 1MVA, to determine whether local diverse networks would have sufficient capacity to accommodate a 1MVA supply for the life safety systems.

UK Power Networks provided response (Ref 8500292677 dated 13th March 2024) outlining the budget estimate to supply the site with the 1,000kVA requested.

It will be necessary to install an 1MVA package substation on site for the customer load of 1MVA. The costs include for UKPN to trench from the point of connection to the customers substation position.

UKPN was unable to provide details in a budget quotation of a truly diverse supply coming from a separate primary substation to the main supply, and that a formal quotation would need to be sought to determine this feasibility.

WSP approached UK Power Networks on the 25th April 2024 to request a formal quotation for a supply of 16.5MVA, to determine whether local networks would have sufficient capacity to accommodate proposals, or whether network reinforcement will be required.

UK Power Networks provided response (Ref 8600031297 dated 24th July 2024) outlining the formal quotation to supply the site with the 16,500kVA requested. The proposal is to provide 4No. 11kV cables from Deptford Grid Substation, feeding 4No. Ring Main Units on the site. The following is from the UKPN quotation Contestable works section.

HV Plant and Switchgear

 Fit actuator to circuit breaker.

 Sand & cap/shingle substation

 300mm HV indoor end box termination

 Installation of secondary substation lighting and power in brick substation.

 Establish an 11kV switchroom within a brick-built chamber. Includes Ring Main Unit with relay, Air Metering Unit, RTU, and switchroom ancillaries. Excludes earthing, civil works, and HV jointing.

 Transport of plant to site in normal weekday working hours

 Installation of a transformer-mounted 11kV Ring Main Unit with relay.

 Installation of a Remote Terminal Unit (RTU).

 Install earthing in brick secondary substation

 High voltage injection test

POTABLE WATER

The incoming potable mains cold water supplies will be fed from the roads surrounding the development. There are potable water mains in both Lewisham High Street to the east and in Molesworth Street to the west.

TELECOMMUNICATIONS

Telecommunications requirements for the emerging masterplan have been discussed between WSP and Landsec ICT teams. The site is surrounded by multiple telecommunications providers’ apparatus, providing significant options for new fibre infrastructure.

Telecommunications operators will typically include, but not be limited to:

 BT Openreach

 Hyperoptic

 Virgin Media

 Colt

 Vodafone

Providers will be aggregates into single ‘meet-me’ chambers located on the development phase boundary with connections made into local utility networks or adjacent phases as is most appropriate given the phase layout and access to adjacent utility networks.

N1 FOUL DRAINAGE STRATEGY

All foul water drainage from the proposed development will drop to the below ground drainage network at drop points specified by WSP MEP team. This network will be routed to the external courtyard and access road, and then outfall via a new 100mm diameter gravity connection to the 600mm diameter Thames Water foul sewer to the North of the site, via a demarcation manhole. This connection is subject to an S106 agreement with Thames Water. Non-return/flap valves are to be located in an accessible location within the network to protect against sewer surcharge.

A pre-development enquiry has been submitted as part of the wider Masterplan proposals, to confirm capacity within the public sewer network for the proposed foul flows.

There are no proposed alterations to the drainage network serving the existing retail units being retained in the north-east part of the site.

Figure 2-1 – Excerpt from Elliott Wood drawing 2230538-EWP-ZZ-XX-DR-C-10001: N1 Below Ground Drainage Proposed Layout

N2 FOUL DRAINAGE

Foul water flows from plot N2 will be collected at a high level and be conveyed to the boundaries of the building, before connecting to the manholes located in the external pavement area via soil vent pipes. It will then connect to the wider WSP proposed masterplan foul network and discharge to the existing 600mm diameter Thames Water (TW) foul sewer located to the south of Rennell Street, via the proposed manhole.

N2 SURFACE WATER DRAINAGE

Sitewide flood risk assessment and surface water drainage strategies is produced by Expedition. N2 surface water drainage strategy has been developed to align with it.

Roof area from the southwest corner of the plot will be picked up by rain water pipe and to be connected to Expedition masterplan podium surface water network.

Roof area from the rest of the plot will be picked up by rain water pipes and to be connected to Expedition masterplan underground surface water network which will discharge to the existing 229mm diameter TW surface water sewer located to the south of Rennell Street, via proposed manhole.

Type C non-infiltration permeable paving is proposed for the external aera, with fin drain proposed at the subbase to collect the runoff and connect to the N2 surface water network.

Sustainable drainage systems (SuDS) will be integrated with the masterplan surface water drainage network which will incorporate attenuation systems and rain gardens.

Attenuation volume for N2 will be provided within the attenuation tank located between plot N1 and N3. It has been sized to accommodate the 1 in 100-year storm event including an allowance of 40% for predicted climate change. As part of the sitewide drainage network, the runoff would be restricted to greenfield rates before discharging to the TW sewer. Refer to Expedition masterplan drainage design for details.

A surface/foul water pre-developmentenquiryhasbeen made to TWto understand if there isadequate capacity to cater the Proposed Development. At the time of writing this report, WSP are still in the progress of liaising with TW

SURFACE WATER QUALITY CONTROL

SuDS provide natural variability in their ability to remove contamination from surface water runoff which drains across a site, therefore the management of water quality is founded on a risk-based approach. The current SuDS Manual (C753) suggests a risk-based approach based on land use type and specific contaminants.

The SuDS Manual (C753), Table 26.1 suggests a Simple Index Approach (SIA) for low risk developments, which follows a three-step process, namely:

 Allocate suitable pollution hazard indices for the proposed land use.

 Select SuDS with a total pollution mitigation index that equals or exceeds the pollution hazard index.

 Where the discharge is protected surface waters or groundwater, consider the need for a more precautionary approach.

To successfully deliver adequate treatment, the chosen SuDS components should have a total pollution mitigation index that equals or exceeds the pollution hazard index.

Total SuDS mitigation index ≥ Pollution hazard index

Where the mitigation index of an individual component is insufficient, two components (or more) in series will be required, where:

Total SuDS mitigation index = mitigation index1 + 0.5 (mitigation index2)

Where:

Mitigation Index n = mitigation index for component n

A factor of 0.5 is used to account for the reduced performance of secondary or tertiary components associated with already reduced inflow concentration.

Pollution Hazard values table below has been produced and builds on information provided within the SuDS Manual.

Figure 2-2 - Pollution Hazard Values

Other Roofs (typically commercial/industrial roofs)

(up to 0.8 where there is potential for metals to leach from roof)

Individual Property driveways, residential car parks. Low traffic roads (e.g. cul-de-sacs, homezones and general access roads) and nonresidential car parks with infrequent change (e.g. schools, offices) – i.e. <300 traffic movements/day.

Commercial Yard and delivery areas, nonresidential parking with frequent change (e.g. hospitals/retail); all roads except low traffic roads and trunk roads/ motorways1

Sites with heavy pollution (e.g. haulage yards, lorry parks, highly frequented lorry approaches to industrial

estates, waste sites); sites where chemicals and fuels (other than domestic fuel oil) are to be delivered, handled, stored, used or manufactured; industrial site; trunk roads and motorways.1

1 Motorways and trunk roads should follow the guidance and risk assessment process set out in Highways Agency (2009).

2 These should only be used if considered appropriate as part of a detailed risk assessment –required for all these land use types (see also SuDS manual Table 4.3). When dealing with high hazard sites, the environmental regulator should first be consulted for pre-permitting advice. This will help to determine the most appropriate treatment approach to the development of a design solution

The development proposal for N2 comprises of residential roof area

Pollution hazard indices shown in the table below have been considered.

Commercial Yard and delivery areas, nonresidential parking with frequent change (e.g. hospitals/retail); all roads except low traffic roadsandtrunk roads/motorways1

Different SuDS Mitigation Indices for each type of SuDS component are identified in figure below (reproduced from Table 26.3 in C753).

Figure 2-4 - SuDS Mitigation Indices for each type of SuDS component

Figure 2-3 - Pollution Hazard Indices

From the tables above, the SuDS mitigation index within the Site is greater than the pollution hazard index, therefore meeting the requirements of the SIA as specified in CIRIA C753. This will be further reviewed during the detailed design with Expedition.

PROPOSED MAINTENANCE STRATEGY

The below drainage requirements table has been produced and builds on information provided within the SuDS Manual; it is expected a suitably qualified maintenance specialist will undertake the work for the entire development.

Greater London Authority – The London Plan

Assessment Criteria

The proposed surface water drainage network should be designed to the following criteria to comply with British and European Standards BS EN 752:2017 and BS EN 16933-2:2017;

No significant surcharging (gravity flow only) for storm flows with a 50% AEP

No flooding for storm flows with a 3% AEP

No flooding off-site or flooding that would present a risk to person or property for storms with a 1% AEP

In line with local and regional standards, a 40% allowance for climate change will be applied to all calculations for network design.

3 NETWORK ALTERATIONS

This section of the report identifies the anticipated affected utilities which will require diversion. A number of services exist within the development and will require diversion / disconnection, including electrical substations, both dedicated to LSC and UKPN Network substations servicing other customers, BT Openreach networks, gas and water connections to units and drainage assets

Services are also located in the highways and footways surrounding the site. Lewisham High Street to the east, Rennell Street to the north, Molesworth Street to the west and south.

Utility record information indicates the presence of utilities in footways in these locations and will require diverting into the highway where the proposed building line is being extended out onto these footways. WSP has engaged with the utility authorities regarding diversionary works, and proposals to route the services in a joint utility trench.

PHASE 1 DIVERSIONS

A number of utilities which currently run in the southern footway of Rennell Street are affected by the proposed alterations to the north, and a coordinated utilities corridor is proposed as part of the enabling works package to clear the development site ahead of pre-construction activities. We would allow a minimum timeframe of 18months to implement this diversion, which means that whilst

Figure 3-1 - Proposed Phase 1 Utility Diversion Route

the RIBA stage 3 works are progressing for Phase 1, the diversions to the north can be undertaken. This will require the submission of C4 (detailed diversion) applications, and the provisioning of detailed information regarding finish levels and a procurement strategy as to how the works will be procured.

The diversions will be most effectively and easily managed through a single works package, an appointed Principal Contractor undertaking the civils work elements (trenching, backfilling and reinstatement), with the utility companies undertaking the design and installation of their services, with WSP acting as the utilities consultant coordinating the designs and preparing the coordinated utilities trench details for the Design & Build contractor to develop for construction.

The Rennell Street utilities corridor is proposed to divert services into Rennel Street Highway and Molesworth Street. At Stage 3, A Ground Penetrating Radar Survey will be required to determine the extent of services in Rennell Street and Molesworth Street and to prove that the proposed utility diversion route is viable.

MASTERPLAN DIVERSIONS

A further utility diversion corridor is anticipated to the south west of the development, where buildings C3, S1, S2 and S4 extend out onto the eastern footway of Molesworth Street. While not in Phase 1, and therefore not on the critical programme path, WSP has sought utility diversionary quotations from affected statutory undertakers, information of which is provided in the utility tracker. See drawing: LSC-WSP-ZZ-ZZ-DR-UT-000016

Figure 3-2 - Molesworth Street Diversion Route (S1,S2, S4), excerpt from LSC-WSP-ZZ-ZZ-DRUT-000016

Elsewhere diversions and disconnections will be managed on a plot by plot basis.

BT and UKPN have apparatus on the LSC development which will require overlaying with the proposed demolition plan to determine when diversions will be required. This detail will be shared as the construction logistics plans are developed.

4 CONCLUSION AND NEXT STEPS

In Summary, existing infrastructure networks have been identified in close proximity to the Lewisham Shopping Centre development.

During this round of consultation, the following has been established.

GENERAL

▪ The utility load assessment is to be reviewed as the scheme develops as changes may affect the estimated loads and findings outlined to date.

▪ Formal construction applications are to be pursued in line with the construction programme.

▪ For utility assets installed in non-adopted/3rd party land it will be necessary to ensure the required legal agreements are in place prior to the on-site works being undertaken.

▪ It will be necessary to undertake intrusive/non-intrusive surveys in key areas to validate record information obtained from the affected utility stakeholders at an appropriate time during the development of the masterplan.

▪ Based on the information obtained to date, it is not anticipated that there will be any utilities or sewerage constraints on the proposed development.

ELECTRIC – PHASE 1

▪ WSP approached UK Power Networks on the 7th March 2024 to request a budget estimate for a supply of 1MVA, to determine whether local networks would have sufficient capacity to accommodate proposals, or whether network reinforcement will be required.

PROPOSED N1 FOUL WATER DRAINAGE

▪ All foul water drainage from the proposed development will drop to the below ground drainage network. This network will be routed to the external courtyard and access road, and then outfall via a new 100mm diameter gravity connection to the 600mm diameter Thames Water foul sewer to the North of the site, via a demarcation manhole. This connection is subject to an S106 agreement with Thames Water. Non-return/flap valves are to be located in an accessible location within the network to protect against sewer surcharge.

▪ A pre-development enquiry has been submitted as part of the wider Masterplan proposals, to confirm capacity within the public sewer network for the proposed foul flows.

▪ There are no proposed alterations to the drainage network serving the existing retail units being retained in the north-east part of the site.

PROPOSED N2 FOUL WATER DRAINAGE

▪ Foul water flows from plot N2 will be collected at a high level and be conveyed to the boundaries of the building, before connecting to the manholes located in the external pavement area via soil vent pipes. It will then connect to the wider WSP proposed masterplan foul network and discharge to the existing 600mm diameter TW foul sewer located to the south of Rennell Street, via proposed manhole.

PROPOSED N2 SURFACE WATER DRAINAGE

▪ Sitewide flood risk assessment and surface water drainage strategies is produced by Expedition. N2 surface water drainage strategy has been developed to align with it.

▪ Roof area from the southwest corner of the plot will be picked up by rain water pipe and to be connected to Expedition masterplan podium surface water network.

▪ Roof area from the rest of the plot will be picked up by rain water pipes and to be connected to Expedition masterplan underground surface water network which will discharge to the existing 229mm diameter TW surface water sewer located to the south of Rennell Street, via proposed manhole.

▪ Type C non-infiltration permeable paving is proposed for the external aera, with fin drain proposed at the subbase to collect the runoff and connect to the N2 surface water network.

▪ Sustainable drainage systems (SuDS) will be integrated with the masterplan surface water drainage network which will incorporate attenuation systems and rain gardens.

▪ Attenuation volume for N2 will be provided within the attenuation tank located between plot N1 and N3. It has been sized to accommodate the 1 in 100-year storm event including an allowance of 40% for predicted climate change. As part of the sitewide drainage network, the runoff would be restricted to greenfield rates before discharging to the TW sewer. Refer to Expedition masterplan drainage design for details.

▪ A surface/foul water pre-development enquiry has been made to TW to understand if there is adequate capacity to cater the Proposed Development. At the time of writing this report, WSP are still in the progress of liaising with TW.

SURFACE WATER QUALITY CONTROL

▪ SuDS provide natural variability in their ability to remove contamination from surface water runoff which drains across a site, therefore the management of water quality is founded on a risk-based approach. The current SuDS Manual (C753) suggests a risk-based approach based on land use type and specific contaminants.

▪ The SuDS Manual (C753), Table 26.1 suggests a Simple Index Approach (SIA) for low risk developments, which follows a three-step process, namely:

▪ Allocate suitable pollution hazard indices for the proposed land use.

▪ Select SuDS with a total pollution mitigation index that equals or exceeds the pollution hazard index.

▪ Where the discharge is protected surface waters or groundwater, consider the need for a more precautionary approach.

▪ To successfully deliver adequate treatment, the chosen SuDS components should have a total pollution mitigation index that equals or exceeds the pollution hazard index.

Dear Mr. Smith

Office Company:

Registered in England and Wales No: 3870728

Date: 13 March 2024

Our Ref: 8500292677 / QID 3000049311

Budget estimate

I am writing to you on behalf of London Power Networks plc the licensed distributor of electricity for the above address trading as and referred to in this Quote as “UK Power Networks”. Thank you for your recent enquiry regarding the above premises

I am pleased to be able to provide you with a budget estimate for the Works.

It is important to note that this budget estimate is intended as a guide only. It may have been prepared without carrying out a site visit or system studies. No enquiry has been made as to the availability of consents or the existence of any ground conditions that may affect the ground works and only a cursory assessment of any Reinforcement costs that may be applicable has been undertaken. A detailed evaluation of any potential Reinforcement costs, including the applicability of the High-Cost Project Threshold and associated Cost Apportionment Factor will be undertaken upon receipt of a formal application for a Connection Offer. This Budget Estimate is not an offer to provide the connection and nor does it reserve any capacity on UK Power Networks’ electricity distribution system.

Description of work included:

The budget estimation for the Works is:

This report constitutes a desktop study, devoid of physical inspections to ascertain the point of connection (PoC). Therefore, it is imperative to acknowledge that the pricing and PoC may undergo alterations during the formal stage.

It will be necessary to install an 1MVA package substation on site for the customer load of 1MVA. The following costs include for UKPN to trench from the point of connection (POC) to the customers substation position. We will accept customer offered single copper cables and terminate to 2 x 800amp way fused at 800amps from adjacent intake room or an 1600amp ACB To establish a backup power supply, UK Power Networks (UKPN) will undertake trenching operations spanning approximately 155 meters to facilitate the installation of another Ring Main Unit. This point of connection (PoC) will be fed from a different feeder, originating from the same primary source.

High Voltage Point Of Connection

£400,000 00 (exclusive of VAT) if the Point Of Connection (POC) is to our High Voltage network along Lewisham High Street and Rennel Street

Assumptions

This budget estimate is based on the following assumptions:

• The most appropriate Point of Connection (POC) is as described above.

• A viable cable or overhead line route exists along the route we have assumed between the Point of Connection (POC) and your site

• In cases where the Point of Connection (POC) is to be at High Voltage, that a substation can be located on your premises at or close to the position we have assumed

• Where electric lines are to be installed in private land UK Power Networks will require an easement in perpetuity for its electric lines and in the case of electrical plant the freehold interest in the substation site, on UK Power Networks terms, without charge and before any work commences

• You will carry out, at no charge to UK Power Networks, all the civil works within the site boundary, including substation bases, substation buildings where applicable and the excavation/reinstatement of cable trenches

• Unless stated in your application, all loads are assumed to be of a resistive nature. Should you intend to install equipment that may cause disturbances on UK Power Networks' electricity distribution system (e.g. motors; welders; etc.) this may affect the estimate considerably

• All UK Power Networks' work is to be carried out as a continuous programme of work that can be completed substantially within 12 months from the acceptance of the Quote

Please note that if any of the assumptions prove to be incorrect, this may have a significant impact on the price in any subsequent Quote. You should note also that UK Power Networks' formal Quote may vary considerably from the budget estimate. If you place reliance upon the budget estimate for budgeting or other planning purposes, you do so at your own risk.

Domestic Reverse Charge VAT Rate

You may be aware of a VAT rate, effective from 1st March 2021, that is referred to as “Domestic Reverse Charge for Construction Services”. I would like to provide you with some clarification about how the Quote is affected.

Section 18 of the HMRC Guidance, which explains the reverse charge treatment for utilities states that “Services provided by utility businesses which do not fall within the domestic reverse charge include the:

• provision of a connection to a utility network, or diversionary works to allow the relocation of the network

• development and construction of a private network to be owned by the utility and leased or sold to the customer

• installation of a boiler (and ancillary supplies)”

You can see the Government’s guidance in full here So in summary, although UK Power Networks is registered under the Construction Industry Scheme (CIS), the provision of connection services to our customers is not regarded as construction services because the work is performed on our own assets. Consequently, there will be no change to the way in which we determine how VAT is applied to this job.

Provision of Service to Build IDNO Networks and VAT

The VAT Rate applied to this job is applicable where UK Power Networks completes all the work (Option A). If you wish to accept Option B or C (where offered) and wish to approach an IDNO to arrange for the Contestable Works to be undertaken (see summary on page 1) the VAT Rate may change and we will issue an invoice to you for the outstanding VAT.

Payment must be made in accordance with the stage payments listed on the Acceptance Form.

To Andy,

Re: Lewisham Shopping Centre, Off Molesworth Street, London SE13 7HB - Budget estimate

Further to your enquiry, I can advise you the outline budget estimated cost to divert our gas apparatus affected by your works would be in order of £550000. The budget estimate cost is based on SGN Completing all the works. and is exclusive of VAT and any allowances that may be applicable. Site visits have not been carried out in support of this estimate and has been carried out solely as a desktop exercise and excludes any associated traffic management and legal costs. Please find attached plan. (routes and lengths are indicative.)

The estimate has been prepared using our current contractors rates for this period and the current applicable overheads. Actual costs applied rates and overheads will be the current applicable rates at the time the works are undertaken.

Where Southern Gas has to divert apparatus, into land belonging to a third party then you must initiate contact with this third party and agree terms relating to a deed of grant (of an easement) for Southern Gas' benefit. You must accept responsibility to pay all costs, and make any payments, that the said third party may incur and/or require in exchange for granting the deed of grant (of an easement) for Southern Gas' benefit. Southern Gas will use reasonable endeavours to assist you with any negotiations that you enter into with the third party, if applicable please confirm the new road scheme will become part of adopted highway and we will require details of solicitors acting on land owners behalf.

We recommend you take out trial holes to determine the route and depth of our gas apparatus in the location of your proposed works and provide us with the details if you wish to request a detailed estimate. Should you decide to take out trial holes to determine the route and depth of our gas apparatus, we have a free Damage Prevention eLearning package "damage-prevention" which takes 10-15 minutes to complete and highlights the importance of working safely near gas pipelines, giving clear guidance on what to do and who to contact before starting any work.

Please contact our Plant Protection Team on 0800 912 1722 who will provide further guidance and assistance. All Proposed works should be registered on linesearch https://lsbud.co.uk Please also view our "Digging safely" web page which includes guidance on working within the vicinity of our gas apparatus "Dig safely Measures to avoid injury and damage to gas pipes" and "Know what's below". All excavation work must be undertaken in accordance with "HSE publication HSG47".

This estimate has been provided to you free of charge and any further estimates relating to this project that maybe required in the future are chargeable (our estimated re-estimate fee for this estimate is 0 excluding VAT, an updated estimated re-estimated fee will be provided on application.). Please contact me should you require any further information or wish to progress to a detailed estimate.

Plant Protection Guidance

Plant Protection working advice and SR18 ed2 extracts.

Areas covered:

• Working in the vicinity of an IP main, SR18 ed2

• Working in the vicinity of a MP gas main

• Work in proximity to an associated gas installation, for example a PRI

• Action in the case of damage to a pipeline

Activities – Work in easements and private land

• Excavation in proximity of gas plant

• Crossing over a pipeline

• Crossing below a pipeline

• Positioning of excavating equipment

• Piling and boring

• Increase of cover

• Safety

Working in the vicinity of an IP main, SR18 ed2

• Removal of bituminous or concrete highway surface layer by mechanical means should be restricted to a depth of 300 mm.

• The use of chain trenchers should not be permitted within 3 m of the pipeline. The operator should consider the risk any work may have on the integrity of the pipeline and, hence, determine the level of monitoring that is required to be carried out by the operator.

• Removal of the bituminous or concrete highway surface layer below 300 mm deep should be by hand-held power assisted tools under the supervision of the operator's responsible person unless, in exceptional circumstances, and following a risk assessment, the operator relaxes these conditions.

• Excavation with a powered mechanical excavator should not be carried out closer than 3 m to a located pipeline and, with hand-held power assisted tools, no closer than 1.5 m. Any fitting, attachment or connecting pipework should be

exposed by hand. All other excavation should be by hand.

• Consideration may be given to a relaxation of these limits by agreement with the operator and while the operator remains on site.

• “No dig” techniques should not be used to cross a pipeline, unless it has been exposed to enable the safe passage of the new service to be observed.

• Any new service running parallel to a pipeline should be laid no closer than 600 mm.

• Where a new service is to cross above or below a pipeline, a clearance of 600 mm should be maintained.

• Whenever a pipeline is exposed, it should be protected by matting and timber cladding. The exposed pipeline should be suitably supported. Where lengths greater than 5 m are to be exposed and unsupported, the promoter/contractor should discuss with the operator the need to undertake a stress analysis to determine support requirements. All temporary supports should be removed prior to backfill.

• Contractors should give operators at least 48 hours of intent to backfill over, under or alongside a pipeline. Any damage to the pipeline coating should be reported immediately to the operator so that repairs can be made prior to backfilling.

• All reinstatement materials and techniques must comply to NRSWA.

• A pipeline should not be encased in concrete.

• Will the gas mains be exposed or not?

If yes, any damage to the coating of the IP however small must be reported to SGN for inspection and repair. This won’t be charged for if it is a minor scrape, if it is not reported and a fault is found at a later date then this will be reported to the HSE as it is a criminal offence to knowingly damage a gas main.

Working in the vicinity of a MP gas main.

• Hand dug trial holes should be undertaken to determine the exact location of pipeline. All excavations within 500 mm of the pipeline should be by hand.

• Where a new service crosses above or below a pipeline, or runs parallel, a clearance of 1.5 times the diameter of the pipeline or 300 mm, whichever is the greater, should be maintained.

Note: This distance may be reduced at the discretion of the operator and subject to adequate

protection being provided.

• The effects of deep excavations around and below a pipeline should be considered in conjunction with the pipe material and MOP.

• All protection requirements should be considered before work commences on site and then reviewed during site operations.

• Any scoring or marking of PE pipes should be reported to the operator who should assess any damage to determine if replacement is required.

• Work in proximity to a ductile iron pipeline should be reported to the operator who should assess any damage to determine if replacement is required.

• Care should be taken to ensure that any cast iron pipeline is suitably protected and supported during works (due to the susceptibility of the material to fracture).

• Extreme care should be taken when working in close proximity to any asbestos or PVC pipeline (due to the susceptibility of the materials to fracture). It is imperative that these are satisfactorily protected and supported.

• All reinstatement materials and techniques must comply with NRSWA.

• A pipeline should not be encased in concrete.

• All unidentified or redundant plant should be considered live until proven otherwise.

Work in proximity to an associated gas installation, for example a PRI

• Where excavations are to be made within 10 m of the perimeter of an associated gas installation, appropriate protection methods should be determined and recorded by the operator.

• Access to the gas plant should be maintained at all times.

Action in the case of damage to a pipeline

If a pipeline is damaged, even slightly, the following precautions should be taken immediately:

• Shut down all plant and machinery and extinguish any potential sources of Ignition

• Evacuate all personnel from the vicinity of the damage

• Notify the operator immediately using the contact telephone number provided or by using the gas emergency number.

• Ensure no one approaches the pipeline.

• Provide assistance as requested by the operator, or emergency services, to safeguard persons or property.

• Ensure no attempt is made to try to stop any leaking gas.

ACTIVITIES – WORK IN EASEMENTS AND PRIVATE LAND

Excavation in proximity of gas plant

• Excavation with a powered mechanical excavator should not be carried out closer than 3 m to a located pipeline and, with hand-held power-assisted tools, no closer than 1.5 m. Any fitting, attachment or connecting pipework should be exposed by hand. All other excavation should be by hand.

Consideration may be given to a relaxation of these limits by agreement with the operator. (PPO decision onsite)

When relaxation is applied, a powered mechanical excavator should not be allowed to excavate closer than 600 mm to the nearest part of the pipeline. This should only be undertaken while the operator's responsible person remains on site.

Where sufficient depth of cover exists following evidence from hand dug trial holes, light, tracked vehicles may be permitted by the operator to strip topsoil to a depth of 250 mm.

• Topsoil or other materials should not be stored within the easement without the written permission of the operator. Topsoil or other materials should not be stored over the pipeline.

• Following works, the level of cover over a pipeline should be the same as that prior to works commencing, unless agreed otherwise with the operator.

• A new service should not be laid parallel to a pipeline, within an easement. In special circumstances, and with the written permission of the operator, this may be relaxed for short excursions in which case the service should be laid no closer than 600 mm to the side of the pipeline.

• Whenever a pipeline is exposed, it should be protected by matting and timber cladding. The exposed pipeline should be suitably supported. Where lengths greater than 5 m are to be exposed and unsupported, the promoter/contractor should discuss with the operator the need to undertake a stress analysis to determine support requirements. All temporary supports should be removed prior to backfill.

Crossing over a pipeline

• Where a new service is to cross over a pipeline, a clearance of 600 mm between the crown of the pipeline and underside of the service should be maintained. If this cannot be achieved; the service should cross below the pipeline

Consideration may be given to a relaxation by agreement with the operator and be undertaken while the operator's responsible person remains on site. Where relaxation applies, the clearance should not be less than 300 mm.

Crossing below a pipeline

• Where a new service is to cross below a pipeline, a clearance of 600 mm between the crown of the service and underside of the pipeline should be maintained.

• An exposed pipeline should be suitably supported. Such support should be removed prior to backfilling.

• An exposed pipeline should be protected by matting and suitable timber cladding.

Positioning of excavating equipment

• Mechanical excavators should not be sited or moved above a pipeline unless written authority has been given by the operator.

• Mechanical excavators should not be sited or moved above a pipeline with the cab positioned on the other side

• Mechanical excavators and other traffic should be positioned far enough away from the trench to prevent trench wall collapse.

Piling and boring

Note: The peak particle velocities indicated apply to all types of seismic and vibration inducing activities.

• Piling or boring should not be allowed within 15 m of buried gas plant without an assessment of the vibration levels at the location of the gas plant.

• For welded steel or PE plant, the peak particle velocity at the plant should be limited to a maximum of 40 mm sec-1.

• Where the peak particle velocity is predicted to exceed 40 mm sec-1, assessment of pipeline stress state, which includes the incremental load due to vibration should be carried out. The vibration loads should be considered as additional to all other relevant and transient loads affecting the pipeline. In addition, an assessment of cyclic loading should be carried out. Where the peak particle velocity is predicted to exceed 30 mm sec-1, the ground vibration should be monitored.

• On a ductile or cast-iron pipeline, the peak particle velocity should not exceed 25 mm sec-1 and leakage surveys should be undertaken at appropriate intervals during the works.

• Where ground conditions are of submerged granular deposits of silt and sand, an assessment of the effect of vibration on settlement and liquefaction at the pipeline should be made.

Increase of cover

• An assessment of pipeline integrity should be made where the depth of cover is increased to 2.4 m or more.

Note: No action is required for an existing pipeline buried at 2.4 m or more except where a change in operating conditions, such as uprating, adding cover, etc. is proposed.

Safety

IF YOU CAUSE or FIND A GAS LEAK OR SMELL GAS

If you cause a gas leak, or suspect that gas pipe or equipment is leaking, you must take the following actions immediately:

• Inform the National Gas Emergency service immediately on 0800 111 999 (all calls are recorded and may be monitored)

• Stop work and get everyone away from the immediate vicinity of the escape.

• Do not attempt to stop the escape or repair by filling the hole.

• Do not attempt to operate any valves (unless directed by the call centre staff to close emergency control valves at domestic properties)

• Prohibit smoking and extinguish all naked flames or other ignition sources for at least 15m from the leakage.

• If escaping gas is entering properties, advise the occupants to leave until it is deemed safe to return by SGN emergency personnel onsite. Damage to a gas main or service supplying a building may result in gas entering the building.

• Prevent any approach to the immediate vicinity of the escape.

Assist SGN and the Emergency services as requested.

Safety Advice - Valves

Guidance when undertaking work near gas valves in our network areas

SGN manages the network that distributes gas to 5.8 million homes and businesses across Scotland and the south of England.

Due to a manufacturing issue, we are currently replacing or upgrading certain valve types that are at risk of bolt failure. In extreme cases, this can lead to gas escapes. This is a safety hazard and we have produced this guide to ensure you undertake adequate safety precautions when working near gas valves.

Identifying gas valves

The images below are an illustration of typical gas valves. Please note, valves come in various colours, shapes and sizes, and you may come across a valve that looks different to those found in the images.

What should you do?

When planning to work in our network areas, please observe the following points:

1. You must contact us before starting any work activity within 3.0m of a gas valve identified on our maps.

2. If an unexpected gas valve is exposed you must immediately stop excavation works and report this to us.

3. To protect yourself against the risks associated with exposing a valve, we advise that you contact us when in doubt

TELECOMMUNICATIONS INFORMATION

How to build a fibre network

Developer Guide

Version 9.6 • May 2022

Copper lines on Openreach New Sites

Openreach has announced its plans to ‘switch off’ the traditional analogue (PSTN) Copper network by the end of 2025.

Between now and then, Openreach will move tranches of exchanges into a ‘stop sell’ position when 75% of addresses in an exchange area can get Ultrafast Full Fibre broadband (also known as Fibre to the Premises or FTTP). This allows us to stop selling Copper WLR and PSTN products to Communication Providers (CPs) at those addresses.

For new sites we want to ensure that we only build one infrastructure which is Ultrafast Full Fibre. We want to remove the dependency on providing small amounts of Copper solely for the purpose of special service lines and from 15 November 2021 Openreach New Sites no longer offers additional Copper for the sole purpose of service lines.

Your equipment providers or CPs should be able to supply an All-IP or GSM based solution for existing Copper reliant services. Please contact them directly to organise these solutions which will allow your sites be fully FTTP serviced.

More information about Copper and FTTP Service Lines on New Sites can be found on our website: openreach.co.uk/propertydevelopment

Internal equipment 1

Openreach Optical Network Termination (ONT) and enclosure

The ONT is the Openreach demarcation point. It replaces the traditional copper master socket.

The Openreach ONT can be housed in an optional enclosure providing space to manage the wiring, keeping everything neat and tidy. The enclosure is designed for simple wall mounting with just two screws. This enclosure can be ordered by your FBC if required.

• Optical port connects to the single ended internal fibre cable (ezbend)

• Ethernet port connects to the communications provider’s (CP) router.

Internal equipment

The enclosure fits over a standard single or double back box, with mounting holes that allow horizontal mounting over a double back box or vertical mounting over a single back box.

Both ONTs shown on the previous page share roughly the same dimensions, making the enclosure able to mount either ONT option.

Please note

The 1+0 ONT no longer contains an Analogue Telephone Adapter (ATA) which converts digital signal into traditional telephony dial tone. Telephony over fibre is now the responsibility of the communication provider, and the home owner may need to plug their telephone into the communication provider’s router.

Homeowners should speak to their chosen service provider about the specifics of voice over fibre when ordering their broadband service.

Home wiring 2

The wiring that you install in your customer’s properties is pivotal to their experience.

Your internal wiring installation options are shown below

Implications of locating the communication provider’s (CP) router in a

cupboard

It is important to note that the Wi-Fi service your customer receives is dependent upon the intended location of the CP router. Placing the router in a service cupboard or under stair cupboard will significantly reduce the speed and coverage your customer will receive.

It is highly recommended that if you position the router in this way that you provide additional RJ45 ports within the home.

Ideally for optimum speeds to be enjoyed using Wi-Fi it is recommended that you locate the router centrally within the property.

For information, advice and guidance around positioning, please refer to: PAS: 2016 Next Generation Access for new Build Homes Guide.

Please note

All internal wires and sockets beyond the ONT are the responsibility of the developer/ future homeowner.

If any part of the single ended internal fibre cable (ezbend) is found to be damaged at commissioning, it is the developer’s responsibility to replace it.

If the homeowner experiences a lack of service or poor service, due to a fault within the internal installation of wiring, which requires Openreach to rectify, the homeowner will be charged.

Please note

All installations of an Openreach ONT require at least 1 power socket to be installed/available in the same location.

An additional socket is recommended if not provided RJ45 network ports throughout the home, as this will be required by the CP router.

Option 1: The simple install

ONT: Optical Network Termination

The simplest installation involves the provision of the Openreach equipment (i.e. the ONT will be positioned adjacent to the outside wall) to which the customer then attaches the router, provided by their communications provider (CP).

This installation limits the number of physical connections to the router and means the homeowner may not make the most of their FTTP connection due to the reliance on wireless connectivity.

Option 2: Relocating the router via internal network cabling

Relocating the communications provider (CP) router provides a better quality wireless connection, as well as the ability to connect static devices such as TVs or games consoles physically. This allows these devices to take full advantage of the high speeds and bandwidth of a Full Fibre connection. Additional Cat6* cabling is required for this option from the ONT to the chosen relocation area. This connection should terminate in an RJ45 socket. A power socket should be provided for the CP router next to this socket.

*Cat6 is the preferred option to ‘future proof’ for modern devices

Further to the second option, this setup cables back from the CP router position within the property to the under stairs/service cupboard position of the Openreach ONT for the location of a patch panel. This means that, as much as possible, any structured cabling is discreetly located out of sight.

A patch panel is the best option to intelligently connect multiple rooms with structured cabling. In this setup a customer could also install an ethernet bridge/switch to further create a truly networked home.

Home wiring

Provision of the Openreach equipment

When Openreach installs the equipment we will install the ONT wherever the incoming fibre cable is located. Where you self-install the ONT, you will have control over when the equipment is installed. The ONT will remain the property of Openreach in both installation scenarios.

Where you are self-installing the Openreach equipment we will supply the ONT and the single ended internal fibre cable (ezbend) you need.

If you are installing the ONT opposite the cable entry hole, you will need to install a flush mounted double back box on the internal wall where the ONT is to be located.

The ONT will be installed at this location unless an alternative position has been agreed with your Field Based Co-ordinator (FBC) and the appropriate single ended internal fibre cable (ezbend) is run in a continuous fault-free length to the alternative position.

Please note

If single ended internal fibre cable (ezbend) is damaged by developers during installation then an internal Splice Point may be required to be fitted to complete installation. This will be undertaken at commissioning stage by Openreach.

Installation of internal cabling

Data cabling recommend

With the shift to full fibre networks, traditional analogue voice services are being phased out. A full fibre network transmits a digital or All IP signal rather than analogue.

In addition, the latest Openreach ONT variants no longer come with an integrated ATA (Analogue Telephone Adaptor). Some CPs may provide an ATA port on their router, but this is dependent on the individual CP and therefore Openreach cannot guarantee the availability. Therefore, we strongly recommend against installing traditional analogue voice cabling and extension sockets around your new build.

Instead, Openreach highly recommends substituting with data cabling. This gives the future homeowner the flexibility to use the extension for data or, by using their own customer procured ATA, traditional voice services. It’s worth noting that most CPs are recommending their customers use VOIP (Voice Over IP) equipment for voice calls rather than ATA’s to convert the FTTP IP signal to analogue. Homeowners can contact their CPs to find out more about the options for voice services.

Developer self-install 3

• As a rule of thumb, single ended internal fibre cable (ezbend) must not exceed the minimum bend radius (i.e. no smaller than) of a £2 coin.

• Detailed information on cable installation and separation is given in the British Standards Code of Practice 6701, Part 1 (particularly clause 6) and the relevant sections of the latest IEE Regulations for electrical installation (Regulation 525 is of particular importance).

• The wiring pattern for cabling must be either series or spur for voice cabling and point to point for data cabling.

• We’d recommend data cabling rooms likely to benefit most from a physical connection, like the room with the main TV and the home office.

Internal Work at defined ONT and Communications

Provider router position

• Fit the electrical socket to the wall. Only a single socket is required for the ONT, however a double socket is recommend if placing the communication provider router next to the ONT.

• Fit the double back box to the wall.

• Fit the slave voice socket to the wall (can be modular to house one voice port and one data port).

• Fit RJ45 modular boxes. The number of these are to be determined by you, the developer, Openreach recommend a minimum of two are fitted, one for the communications provider router and the other to the room requiring streaming media for example for streaming high definition TV. See the internal wiring section for further information.

• All internal wiring to be run back to this point (daisy chain for voice and point to point for data).

• See below for the recommended layout of sockets on the wall, the layout can be mirrored.

ONT position

Developer self-install

Single dwelling unit at second fix (Internal Work)

• Remove the double back box faceplate and feed the fibre cable through the large hold in the back of the casing.

• Attach the casing to the back box. If mounting over the back box is not an option, the casing can be attached directly to the wall using the supplied mounting template.

• Attach the ONT to the casing using the mounting pegs. If using a Nokia ONT, ensure the 3 spacer pegs on the casing are removed first.

• Clean both the pre-connectorised green end of the internal fibre cable and the Optical port of the ONT before inserting the cable.

A video showing the installation of the internal equipment can be found on the Openreach developer website: openreach.com/fibre-broadband/fibre-for-developers/ how-to-self-install-openreach-equipment

Remove the cap from the green fibre connector and the stopper covering the ONT port, disposing of both. Clean the now exposed fibre plug and the port of the ONT using a click cleaner or cleaning swabs.

More information about how to use these cleaning products is available on the Resources page of the stickler website: sticklers.microcare.com/resources/?fwp_resource_ type=howto -can we do a friendlier URL for this?

Developer self-install

• Connect the ethernet cable the PORT port on the ONT. The other end of this cable will be connected to the CP router or internal data cabling port.

• Connect the mains adaptor to the ONT and plug into the mains socket.

Next steps

• Once the plot is complete contact your Openreach FBC as each plot is ready for connection (i.e. front door on; power on, ONT area decorated).

• Your Openreach FBC will then raise a job with the Openreach teams to commission the plot(s).

Cabling and ONT positioning 4

Single dwelling units

For single dwelling units single ended internal fibre cable (ezbend) will be available in different lengths (20m and 30m) and will be delivered on drums that can be ordered via the FBC.

Enough excess must be left coiled externally to allow connection to the cable coming from the duct, but without too much excess slack.

Installation of preconnectorised cable at first fix (Internal Work)

Coil 1m of the pre-connectorised end of the cable into the empty double back box, taking care not to damage the green connector, then fit a blanking plate to help protect the fibre. Ensure the cap on the end of the green connector is kept on during construction to avoid damage to the fibre.

The other (bare) end of the single ended internal fibre cable (ezbend) should be installed internally to externally, as only the green SC-APC connector needs to go to the ONT mounting point. Feed the cable through the external wall to the splicing point outside of the property, ready for Openreach to connect.

Around 2-3m of cable is required to be left coiled externally, the cable can be cut and the end covered with electrical tape if needed to keep the right amount coiled outsaide the house. Avoid leaving any unnecessary slack cable in the wall cavity of the house.

Around 2-3m of cable is required to be left coiled externally.

Once the cable is installed then Openreach (or their third party) will visit to connect the cables from the plot back to the serving splitter location(s), mount the external capping and then commission the plot.

Cabling and ONT positioning

Complying with building regulations

Even where you are not working with Openreach or another infrastructure company to provide a functioning broadband and phone infrastructure to the home, the Part R regulations require the provision of duct in the default position discussed below so that infrastructure can be installed in the future.

ONT in the default position

When the ONT is to be fitted in the default position on an internal wall directly opposite the entry position of the service access hole adjacent to the external duct location, external capping will be fitted on completion.

To keep things tidy, make sure that the service access hole is drilled in line with the duct and in keeping with the dimensions shown opposite.

The service will be sealed with a grommet or mastic before fitting the external capping.

Completed external presentation with capping

Please note

All internal wires and sockets beyond the ONT are the responsibility of the developer/future homeowner. Any faults or defects resulting in an Openreach visit may incur a charge.

External presentation by developer

Cabling and ONT positioning

Wherever possible, the duct shall be positioned on the opposite side of the wall to where the ONT will be installed, removing the need to run internal fibre cables.

However, there are cases where the kit will need to be installed away from the external lead in and your FBC will be able to advise.

ONT installed inside the house (non-default position)

When the ONT is to be fitted in a non-default position i.e. not directly behind the external entry point, such as in a utility cupboard, the above guidelines must be followed to provide entry of the cable into the home.

What will be different is the length of cable that will run from the entry point into the building to the Openreach ONT. In this case you have the responsibility of running the single ended internal fibre cable (ezbend) required inside the house in such a way that it is undamaged and complies with building regulations for the installation of telecommunications infrastructure cabling.

The same rules apply to the running of fibre cable internally that are specified in the section on exterior ducting. For example, the installation of the fibre cable in protective conduit and the absence of a bend more than 90°. Once installed the ONT must be kept powered on.

If this option is followed but the cable is found to be damaged once in situ during construction work inside the property, cables must be replaced before the fibre service can be tested and called off by your Openreach FBC.

The developer must run the single ended internal fibre cable (ezbend) in a continuous length, ensuring it remains free from any damage that could reduce the lifespan of the cable, and keep the capping on the connectorised end of the cable until the installation is complete.

Enough excess must be left coiled externally to allow connection to the cable coming from the duct, but without too much excess slack. Around 2-3m of cable is required to be left coiled externally.

A 1m portion of the internal cable should be left coiled and housed within a flush mounted double back box and faceplate ready for Openreach provision of the ONT.

It is important to select the right cable to achieve the minimum excess slack. Any unavoidable extra slack should be stored in a no drill zone wall cavity, taking great care not to loop the cable tightly as this will cause the cable to fail.

Cabling and ONT positioning

Interconnecting voice lead (Item Code 077004) will be provided free of charge by Openreach. It provides connectivity from the ONT to a co-located voice socket/patch panel. On installation it becomes the property of the homeowner. Alternatively, the developer may choose to hardwire directly into a voice socket using a 431A Plug.

Multiple dwelling unit (external)

• Fit all external duct from the site connection point to the building entry position.

• Fit all tray work from the building entry position to and up the risers to the internal splitter position(s).

• Run the fibre cable from the splitter or fibre node/budi location to (and in) the riser to the communications room.

• Coil a minimum of 2m in the communications room.

• Coil a minimum of 2m at internal splitter position.

• Ensuring bend radius of cable must meet all necessary installation requirements i.e. no 90 degree bends (as per current copper process).

• If the risers are away from the point of entry but fed through a vented car park then the external cable can be fed on tray work.

• If the risers are away from point of entry and fed through a non-vented car park then an area needs to be allowed within 2m of point of entry to change from external to internal cable.

Multiple dwelling unit

– Next Steps

• Once ductwork and cable has been run from communications room to Fibre DP/budi –contact FBC to gain confirmation that all cables are run correctly.

• FBC will then raise a job with the Openreach Internal teams to commission the splitter(s).

• Once commissioning is complete contact FBC as each plot is ready for connection (front door on, power on, ONT location is decorated).

• FBC will then raise a job with the Openreach internal teams to commission the plot(s).

Fire stopping compartment penetrations

All holes drilled through floors and fire compartment walls must be fire proofed using correct materials to prevent the spread of smoke in the event of a fire. Openreach can provide these materials in either cartridge (similar to silicone sealant) or putty form.

Cabling and ONT positioning

Fixing cables securely

If you’re running any cables through a fire protected area like a fire escape route, escape staircase or walkway, the cable must be adequately secured using noncombustible fixings.

Wiring regulations must be followed, ensuring that wiring systems in escape routes are supported in such a way that they will not be liable to premature collapse in the event of fire. This applies to all cabling and not just electrical cables e.g. alarm, telecoms and control wiring. From January 2019 this will apply throughout the installation as the 18th Edition wiring regulations come into force.

Issues with home wiring

• Single ended internal fibre cable (ezbend) too short, cut or damaged.

• Defective or damaged home wiring creating a fault on the line.

• Extension sockets not connected to Openreach ONT.

• Bending radii exceeded causing reduced levels of service due to fibre being broken or the bend was too tight.

• Incorrect cable type or wiring configuration.

Impact on delivery

• Inability for Openreach to provide service and developer requirement to re-provide single ended internal fibre cable (ezbend).

• Poor user experience for home purchaser with possibility of Openreach charges if called upon to rectify.

• Slower data download speeds experienced.

Impact on delivery of issues

• Delay in completion – Openreach may refuse to cable if we can’t guarantee adequate protection.

• The capping and covers would look unsightly.

• Failure to provide conduit can prevent a cable from being installed.

• Customers may not be able to place orders and remedial work may incur additional costs.

Internal Duct Feed

Duct 56 to Property (Under Slab)

Duct 56 From Network (Underground)

Footway box

If internal duct feed to SDU plots is provided then under no circumstance should a section of duct feed directly from the underground jointing chamber to the inside of the house.

This is due to the risk of gas passing from the underground network directly into the house. Instead, Openreach will only support internal duct feeds where there is a separate duct section from the underground jointing chamber to the exterior of the house and then a secondary separate duct which feeds under and then inside the house.

The two duct mouths on the external house should be located as close to each other as practically possible. Currently, Openreach does not have a double duct capping and cover solution, but we are trialling some designs with industry.

The only current solution is to provide two separate capping and covers side-by-side. Depending on the distance between the two cappings the fibre cable will be partly exposed on the outside wall of the house.

We are working closely with industry in regards to Modular and Passive Homes to ensure our installation methods comply with the building standards and methods being employed. If you are building houses of this type then we will develop a solution as part of the site design if our standard installation methods are not suitable.

Any internal duct feed must be sealed to prevent gas or water ingress. The required sealant can be provided by your Openreach FBC.

Multi dwelling units (MDUs)

Openreach will create a fibre layout based on your Mechanical & Electrical (M&E) drawings (on larger MDUs) of the MDU. The design will calculate the materials required to build the network. Your FBC is on hand to guide you through the ordering process to make sure the equipment is available when you need it. The incoming Duct 54 and fibre cable will terminate in the communications intake room or riser cupboard. This needs to be a secure and safe location with access for installation and any future maintenance visits.

Our fibre box/splitter needs to be installed at a minimum height of 200mm and a maximum of 1500mm.

Small MDUs

Your FBC will agree the location with you. Connectorised internal fibre cable needs to be run from each plot to the fibre DP location or basement box, depending on MDU layout. A minimum of 3m of coiled cable needs to be left at the fibre DP, with 1m left at the plot end. On most MDUs a tail cable may be required to be run from the floor DP down the riser to the basement box. A wayleave may be required from the building owner prior to installing apparatus in common areas.

Any internal duct feed must be sealed to prevent gas or water ingress. The required sealant can be provided by your Openreach FBC.

Fibre cable

Multi dwelling units (MDUs)

Option where Openreach installs the equipment

When Openreach is to install the ONT, 3m of cable is required at the splitter/ floor DP location and 1m (2m if non-connectorised cable) at the ONT end of the installation.

Each apartment will require a designated connectorised internal fibre cable run in a continuous fault-free condition from the designated ONT location within the apartment to the floor DP within the riser.

At the splitter locations the cable should be clearly marked with the apartment number and left safely coiled within the riser.

• Install a flush mounted double back box at the desired ONT location.

• Install the connectorised fibre cable from this point to the designated riser termination point.

• Ensure there is 1m of spare connectorised fibre cable protruding from the back box.

• Push some of the spare cable back into the wall void and coil the remainder inside the back box, taking care not to damage the connectorised end.

• Install blanking plate or brushed face plate to protect cable ready for provision of ONT nearby.

Your FBC will advise of all cable marking/ labelling and will check for this when ‘calling off’ the work.

IET wiring regulations must be followed.

External cables can run to a maximum of 2m from the internal building entry point.

From this point onwards, all external cables must be terminated or transitioned to internal fibre cables to comply with Fire Safety Regulation BS7671.

Bends in fibre cable must be kept to a minimum and the installation of trunking, cable trays/grids shall not compromise the bending radii.

Fibre cable containing no metal parts can be run on shared trays. Plate cable fixings with cable ties must be used to fix fibre cable direct to walls to avoid it being damaged.

Under no circumstances should cable or tubing be secured to or supported by the suspended ceiling hangers or under floor support legs.It is the developer’s responsibility to provide fire stopping on completion of the cable/tubing installation.

Openreach networks must not interfere with or be interfered with by other services within the riser or any other shared space, such as:

• Un-insulated hot water pipes.

• Unscreened mains cables.

• Fluorescent lighting.

• Heavy duty switch gear.

A wayleave may be required from the building owner prior to installing apparatus in common areas. Remember you may need to order copper lines for commercial properties, for example lift lines.

Conduit or trunking must not be used to carry external fibre cables beyond 2 metres from the building entry point. Your FBC can provide more guidance if needed.

Internal fibre cable must not be bent beyond its minimum radius. If it has been damaged or there is evidence of kinking it shall be discarded. Your FBC will advise on replacement of the cable.

Care should be taken to avoid stretching cable/tubes through installation. If cables are damaged this way you will be required to replace them.

Duct laying 8

Carriageway Road Crossings

Where our duct crosses a carriageway, adjoining kerbs must be temporarily marked to note positions. Openreach duct must be laid on an outer edge of the service trench to enable box building. A draw rope will be inserted through the duct and secured to the marker posts at both ends of the crossing. The appropriate Plug Duct 4B socket end and 4C Spigot is then fitted.

Duct laid beneath a carriageway crossing must be a minimum of 450mm depth from the cover of the final surface levels and, for engineering reasons (Streetworks UK), separated from other services laid in parallel by 450mm (to permit us to install underground joint boxes without the need for bends).

Ducting to the building

Duct to the premises/building must be laid at a minimum depth of 250mm and be as straight as possible.

Ducting general principles

• All runs shall be laid as straight as possible. If needed, you can carefully bend the ducts or use pre-formed bends supplied by Openreach.

• There shall be no more than one pre-formed 90° bend in any single run of duct.

• Pre-formed 90° bends shall not be installed in any duct linking two joint boxes.

• Footpath or service strip ducting must be laid at a minimum of 250mm depth of cover.

• All space alongside the duct must be backfilled with granular fill to a minimum thickness of 75mm.

• For all single dwelling units (SDU) duct must be terminated on the external surface of the property.

• The duct termination point must be in a location that will allow unrestricted access for any future maintenance activity.

• All ducts must be provided with a draw rope after installation, unless it’s agreed locally to substitute the draw rope with a cable.

• Please notify your FBC when the duct has been laid and is ready for inspection.

Any internal duct feed must be sealed to prevent gas or water ingress. The required sealant can be provided by your Openreach FBC.

Commercial unit ducting

• 90mm duct can be laid either externally or internally to the building, with 90 degree angled bend.

• If internally then the duct should be sealed once cabling is complete – the FBC will provide this as a stores item.

• The termination point on a large commercial unit within a commercial only site should be located within 10m of the entry point.

Detectable Buried Service Warning Tape

• Traceable warning tape must be installed on your site above all new duct and direct-inground cable as no locator signal can be sent over fibre cables.

• Warning tape with a traceable wire running through it will allow other utilities to locate our network prior to excavation and help our Plant Protection Officers accurately mark-up network positions.

• Tape must be placed 50mm above the installed duct or cable, in footways and carriageways.

• Installation of tape on site falls under current SOD rebate requirements.

• Tape will be ordered by your FBC alongside other free issue materials.

• Tape is a newly introduced item, therefore to locate existing cables on site please follow the existing guides and processes on locating our network on our website: openreach.com/ building-developers-and-projects/locatingour-network

Avoiding damage to the Openreach underground network

Openreach has an extensive underground network that can be located inside/on the perimeter of a site.

This network is vulnerable to excavation related damage unless appropriate precautions are taken.

The precautions for avoiding damage to an underground utility plant are contained within the Health & Safety Guide no. 47: “Avoiding danger from underground services”.

Available here: hse.gov.uk/pubns/books/hsg47.htm

This document stresses the need for the availability of utility plans on site and the use of safe digging practices.

Damage to the Openreach network by a third party can be expensive for that party to repair.

By working together, we want to make sure you avoid the repair and associated cost which can consist of one or more of the following:

• Direct Cost – the cost of repair.

• Operational Cost – delays associated with repair.

• Social Cost – loss of service to emergency services/centres or the vulnerable in society.

Typical issues with carriageway road crossings

• Insufficient depth.

• Proximity to other services.

Impact of issues

You will have to renew duct and this may delay any first occupation date or subsequent occupation dates.

If you need to move or consult on existing Openreach equipment, contact us on 0800 783 2023 or complete the online webform at: openreach.com/help-and-support Click Before You Dig

To obtain a more precise location of Openreach infrastructure (either within your site or the adjoining land) and avoid costly damage, email cbyd@openreach.co.uk

Utilisation of the Openreach “Click Before You Dig” free service has a proven record of minimising the potential for damage and cost.

Modular jointing chambers – QuadboxTM 9

The optional approved pre-formed chamber system Quadbox™ can be used to speed up the installation process and bring significant productivity benefits as there is no need for specialist box building teams and concrete backfill to be used.

The Quadbox™ is not a free stores item from Openreach, but can be purchased directly from our approved supplier, Radius Systems. For purchasing enquiries please contact the sales and marketing manager for Radius at the following details:

Sandra Davoust McCann

Email: Sandra.DavoustMcCann@ radius-systems.com

Tel: +44 (0)28 3844 6060

Quadboxes can also be sourced from a number of nationwide builders’ merchants. This may be more suitable for smaller sites that need lower quantities.

Joint box modular footways 104 and 106 are the Openreach approved versions (BT specification LN712). Box furniture items slot into moulded pockets within the chamber, eliminating the need to cast-in fixings or drill on site. Duct entries are also easy to achieve, using a standard hole saw mounted on a cordless drill.

The lightweight high-strength system is supplied as 150mm deep twin wall high-density polyethylene (HDPE) rings to provide maximum flexibility and strength which are simply stacked on a prepared base and backfilled with suitable as-dug or Type 1 material.

See the suppliers Installation Guide which comes with your box. If purchasing a preformed chamber please speak to your FBC who can order all associated box furniture.

Modular jointing chambers – QuadboxTM

Furniture

Cable brackets and steps (where required) are supplied in a bagged kit and easily slot into purpose designed pockets in the chamber. The brackets and steps drop into preformed slots.

Available Size Range

At least 5 sections are needed to meet the minimum box depth of 750mm.

Modular jointing chambers – QuadboxTM

Duct entries

Duct entries can be cut as and where required using a hole saw mounted on a cordless drill.

The chambers incorporate guides which identify drilling points to ensure correct duct spacing.

A maximum of 4 duct entries can be made into a single wall of the Quadbox™.

Quadbox points of note

Camber Adjustment

If the frame requires levelling to the ground surface, or to a newly raised surface level, rising frame units (as shown) are available as an option. These should be used in conjunction with mortar to build the frame up to the required level. Where levels mean that the cover needs raised by more than the 50mm allowable mortar bed, bricks, quarry tiles etc. should not be used to adjust the height of the cover.

A further Quadbox section should be cut horizontally (minimum depth to be a 40mm wall section), with the voids of the cut chamber filled with C32/C40 concrete or mortar.

As with brick built chambers, care should be taken to make sure:

• The box is set at the correct depth and the base/plinth is installed correctly.

• The side wall is not damaged/misshapen due to over compaction.

• The frame is level with the surface and a core drill is used for cutting duct entries.

• The wall bearers are provided by Openreach and can be ordered by your FBC.

Frames and Covers

Cubis Industries is the only supplier of these Openreach approved products.

Only approved frames and covers shall be fitted on your site. They are identifiable by the following markings; ‘EN24 B125’ the British Standards kitemark the Manufacturer Mark (SID), the year of manufacture and the BT identifier.

The ‘standard frames and covers’ are supplied by Openreach. They consist of a galvanised steel fabricated frame, fitted with unfilled galvanised steel fabricated cover trays and cross-beams.

All covers can be fitted to brick or concrete.

Please note

Where there’s evidence or high risk of vehicles using the soft verge e.g. as an undertaking area opposite a T-Junction, a passing point on a narrow road or a parking area, it will be necessary to install a ‘carriageway chamber, frame and cover’. There is also an optional ‘recessed frame and cover’.

Recessed frames and covers

These can be purchased by the installer as an option to the ‘standard frame and cover’.

Each cover tray has two key-hole fittings (in the centre of the short side) one of which carries a BT identity mark and the manufacturers’ three letter identification ‘SID’. The other key-hole fitting displays EN124 and B125 together with the BSI Kite mark certifying the covers to BS EN124: 1994. Recessed frames and covers will accommodate infill blocks to a maximum depth of 60mm. If you’re planning to install frames and covers that aren’t supplied by Openreach e.g. for block paving, or you have any doubts about what frames and covers to use, please speak to your FBC.

Joint boxes, footways and frames & covers

Installation

All frames and covers shall be levelled to the final running surface. Where a box is located within grass, soft or unmade surfaces, the frame shall be surrounded with a 100mm wide strip of minimum grade C25/30 concrete, to the full depth of the frame, finished level with the top edge of the frame and the outside edge. It must be straight and parallel to the frame.

Unapproved frames and covers

Unapproved frames and covers must not be fitted. Openreach will take any necessary action against any developer who fits unapproved frames and covers within the network, including any potential claim for damages and costs, with possible delayed Service On Demand (SOD) payments. If you’re unsure how to specify approved covers, please contact your FBC.

Dropped kerb and shared surface chamber boxes

If your site has shared surfaces for roads and footways, please ensure the correct joint box is installed based on the following guidelines.

• There must be a defined kerb line between the road and footway to install a footway spec box or modular quadbox in the footway area

• If no defined kerb line is present, a carriageway spec box must be installed as regular traffic could pass over these areas

• Driveways attached to houses and entrances to service areas do not require a carriageway spec box, so footway and modular quadboxes can be used for these areas

Health and safety advice

This guidance is a practical aid for designers and site workers on what to eliminate, avoid and consider when working on the Openreach network on your site.

The advice is not exhaustive so speak to your Field Based Co-Ordinator (FBC) if you need further information.

Red lists

Hazardous procedures, products and processes that should be eliminated from the project where possible

Distribution point (DP) location

• Placing DPs into voids or other enclosed spaces with inadequate ventilation.

• Placing DPs adjacent to, or above, any fragile surface.

• Placing DPs directly above, or adjacent to, water features/courses etc.

• Locating DP at greater than 1.5 meters above finished floor level (without fixed access system incorporated into design).

Power systems

• Ensure all power installation meets relevant standards, and where DC supplies are planned seek further advice about requirements for earthing of racks, power supply ratings etc. to take account of future needs and growth.

Cabling routes and lead-ins

• Routing of cables where the cables are above head height within false ceiling systems without a proper access system incorporated.

• Routing of cables external to building requiring specialist access methods (scaffold, mobile elevating work platform etc.)

• No internal ducting laid into single dwelling units (SDUs).

Aerial and antenna transmission/ receiver systems

• Not mounted on building walls or other difficult to reach areas of a building.

• Design of roof mounted services that require access (for maintenance and so on), without provision for safe access (such as barriers) in particular access for aerials/antennas systems.

Joint boxes, footways and frames & covers

Amber lists

Products, processes and procedures to be eliminated or reduced as far as possible and only specified or allowed if unavoidable. Including amber items would always lead to the provision of information to the principal contract or contractor where only one contractor has been appointed.

Distribution point (DP) location

• DPs located into voids or enclosed spaces provided with ventilation systems built in.

Aerial and antenna transmission/ receiver systems

• EMF exclusion zones adequately managed with fixed barriers or partitioning systems.

Cabling routes and lead-ins

• Routing of cables where the cables are above head height within false ceiling systems.

• Routing of cables internally where access points require use of access equipment (ladders, step-ladders or platform steps) to allow for pulling in of cables.

Green lists

Products, processes and procedures to be positively encouraged.

• Adequate access for vehicles to minimise reversing requirements (one-way systems and turning radii) in particular if specialist vehicles will need access (pole erection units, MEWP vehicles etc.).

• Provision of adequate access and headroom for maintenance in communications rooms, and adequate provision for replacing heavy components.

• Thoughtful location of mechanical and electrical equipment, such as telecoms equipment, termination points, Wi-Fi transceivers etc. and so on to facilitate access, and placed away from crowded areas.

• Lighting within communications rooms adequate for fine tasks (fibre splicing, small diameter copper wire terminations etc.)

• Provision of adequate air handling/ conditioning and ventilation for the installed equipment base within the communications room (and people having to access and work within the area).

• Early installation of permanent means of access, and prefabricated access systems with hand rails.

• Provision of edge protection at permanent works where there is a foreseeable risk of falls after handover (consider radio antenna or aerials installations on roof spaces).

• Encourage the use of engineering controls to minimise the use of personal protective equipment.

Quality control checklist 13

To help make sure your site network is built to a high quality standard, we’ve produced a checklist for each phase of the build. Your FBC will complete an online version of this checklist at each stage, this list can be used as a reference.

Any subsequent changes to the site plan after stages have been signed off must be communicated and agreed with your FBC as soon as possible.

Any re-work as a result of an out of date site plan could cause delivery delay and incur you costs in time related charges.

If you have any questions about your development, please visit: openreach.com/fibre-broadband/fibre-for-developers or call us on 0800 783 2023

Psychical Infrastructure Access (PIA)

PIA allows non-Openreach network providers to share Openreach’s network infrastructure, which on Full Fibre new sites consists mainly of ducts and chamber boxes. PIA can also be used to share telegraph poles as well as underground infrastructure.

PIA allows multiple network providers to deliver service on a new site development without requiring different ducts and chamber boxes for each service.

Non-Openreach network providers will have to be invited onto site by you as a developer to be a part of a PIA delivery, Openreach is unable to provide this initial contact. If you have a nonOpenreach network provider interested in a PIA product, inform your Openreach FBC and they will guide you through the following steps.

• An initial site meeting between you the developer, your Openreach FBC and the nonOpenreach network provider will be completed to discuss the PIA proposal

• Your FBC will share the required quality standards with you the developer and the nonOpenreach network provider

• Your FBC will perform a series of checks to ensure the non-Openreach network provider has various requirements in place to allow the PIA product to be legally used

• Your FBC will confirm when the duct and chamber box work has been completed to allow the non-Openreach network provider to install their equipment

Please ensure your FBC is made aware of any non-Openreach network planned to be installed on site during your initial site visit to allow the above process to be followed.

More information about PIA can be found on the Openreach website: openreach.co.uk/cpportal/products/passive-products/physical-infrastructure-access(PIA)

Network connectivity for commercial new sites

Modern commercial sites require network ready for the demands of connected businesses. Openreach provides your commercial developments with a modern platform for businesses to enable the connectivity they need, using the provider of their choice through our unrivalled open-access network.

Our full fibre network delivers ultrafast speeds and varied connection options depending on the type of site being built. From multinational distribution hubs to sole traders working from home, Openreach full fibre networks power business connectivity across the country.

Network in Advance

Ensure your commercial site is ready for connection with no delays

When connecting a new commercial development to Openreach infrastructure, much of the work is done off-site. Bringing the network from the telephone exchange to your site can require passing through city centres, motorways, or other developed areas. It can take weeks or months to get planning permission alone for these areas, causing huge delays if not prepared. Our Network in Advance (NIA) service can help deliver key network infrastructure off-site before a formal order is placed. Our commercial specialists and project managers will work with you at the earliest stages of your development, providing a full plan and works to deliver network to the edge of your site as early as possible.

Connection Types

Shorten lead times on remote sites by building the off-site infrastructure as soon as possible

Prevent delays due to other work being performed in areas where Openreach infrastructure must be installed

Ensure complex, city centre sites are connected in time by early planning of traffic and other civil permissions

The right network type for your site and the businesses you work with

Ethernet Access Direct (EAD)

Ethernet offers everything a modern business could need for their network solution. From small companies reliant on e-commerce for revenue to multinational corporations working on cloudbased systems. Ethernet delivers a dedicated cable straight from the exchange into a single business property. There’s no shared network so ultra-low latency is guaranteed. This dedicated line allows speeds more than 10 times faster than our standard Fibre to the Premises offering.

Fibre to the Premises (FTTP)

FTTP is our standard full fibre option. It’s affordable and reliable, using the same network technology as an FTTP home connection. It delivers all the key benefits of fibre technology. FTTP is a pure fibre connection that runs from the exchange to the edge of your development, where it can deliver service to a single unit or be split to deliver shared service to several smaller businesses.
