Minimise Gutter Flooding Risk The high-front gutters, introduced in the early 1990s, favoured by architects for their aesthetic appeal and embraced by builders because of the spring clip system which quickly attaches it to the metal facia, can result in internal flooding (see diagram). These problems can manifest where eaves are not installed i.e. no overhang from the external wall to the gutter line. An eaves gutter should, in the event of a total blockage of its downpipes or stormwater trains, discharge all roof water clear of the building via overflows. Where high-fronted gutters are installed, provision must be made to avoid any overflow back into the roof or building structure by installing slotted gutters or overflows.

High front gutter

Overflow water Water damage into cavity inside the structure Fascia of the building from overflowing Some overflow gutters can go Stud wall from behind fascia undetected for several months and by then the fabric of the building can be severely compromised. An example of the extent of damage may be bowed or sagging ceilings or rotting framing members.

Downpipes must only serve a maximum of 12 metres of gutter. This is to ensure effective fall and adequate capacity to discharge all water anticipated during heavy rain. It is also necessary to design and install the gutter system so that when overflowing occurs outside the building any water is directed away from the building in a manner which ensures it does not pond near to the footings. Downpipes, especially near valley gutters, should be designed to ensure that rainwater from roof areas with concentrated water flows perform adequately. If downpipe spacings are to be increased, allowance for overflow should be considered Consideration needs to be given to box gutters, valley gutters etc. located above the internal areas of a building. In these situations if adequate overflow controls cannot be implemented there may be a need to increase the size and capacity of drainage components to remove all water in heavy rain periods.

Technical Amendment to the Territory Plan Amendments to Single Dwelling Development Code On Saturday 31 May 2008, an advertisement appeared in The Canberra Times announcing proposed changes to the Single Dwelling Development Codes. Members of the public are invited to comment on these proposed changes. The Master Builders Association of the ACT has had a lot of enquiries, complaints and comments on the new planning system and in particular changes to the Residential Development Codes. As your association we have expressed your concerns to ACTPLA and hence the changes announced. ACTPLA’s objective is to also have the approval system run smoothly and more quickly, so they do recognise and take in constructive comments. This brings us back to the announcement. The advertisement directs you to the ACTPLA website, which then takes you to the proposed technical amendment in PDF format. To make it easier the following is an explanation of the proposed changes.

Part A (1)-RZ1-Suburban Zone, Element 1 Section 1.1 Subdivision of Blocks, Rule R1 Explanation Rule R1 has been reworded to clarify subdivision of existing blocks and to incorporate the allowance for blocks that had a development approval subsequent to Variation 200 (which allowed blocks with an A10 overlay to be subdivided) and prior to Variation 260 (removal of the A10 overlay to some blocks) to still be able to be subdivided. What this means to you Basically blocks in the RZ1 – Suburban Zone cannot be subdivided including unit titles subdivision. It does have a provision to allow blocks that had previously been subdivided (dual and triple occupancies) to comply with the new codes.

Part A (2)-RZ2 Suburban Core Zone, Element 2 Building and Site controls, Rule R6A Explanation Rule R6A has been added so that the 50% plot ratio limit in the Suburban Core Zone for redevelopment on standard blocks will be re-inserted into the current Territory Plan. What this means to you Blocks in the RZ2 Suburban Core Zone will have a 50% plot ratio as is required in the RZ1–Suburban Zone.

Part B General Development Controls, Element 1 Restrictions on Use Section 1.1 Subdivision of Existing Residential Leases (except RZ1 Zone), Rule R14 Explanation Rule R14 has been reworded to clarify subdivision of existing Leases. What this means to you Blocks in Residential Zones (except in RZ1 Zones) that are to be subdivided (dual and triple occupancy) must comply with the Unit Tiles Act 2001. It also clarifies that minor boundary adjustments are not included as subdivision.

Part B General Development Controls, Element 2 Building and Site Controls Section 2.3 Estate Development Plans Approved up to 31/3/2008, Rule R17 Explanation Rule R17 has been reworded to clarify the relationship between lease and development conditions for Estate Development Plans for consideration of a development to be exempt from Development Approval. A criterion has been added to enable a development that does not comply with this rule to be considered under merit track. This change is proposed to be added to the Mixed Use Code to enable the residential component to be consistent with the single and multi-unit residential codes. What this means to you Lease and Development Conditions for estates lodged or approved before 31 March 2008, have the same status as Precinct Plans and therefore take precedence over the Codes. This means that a development proposal that complies with the Lease and Development Conditions and has developer’s consent can be treated as an exempt development. However with the new changes a criterion has been added if the development proposal does not meet the Lease and Development Conditions it can now be assessed in the merit track.

Part B General Development Controls, Element 7 Services Section 7.1 Waste Management, Rule R26 Explanation To reduce the amount of documentation required to be submitted a waste management endorsement from Territory and Municipal Services (TAMS) will only be required if the development will generate more than 5 cubic metres of waste. The clearance for site servicing will not be required for single dwelling applications. What this means to you A statement of compliance from TAMS is only required if the development is going to create more than 5 cubic metres of demolition and/or construction waste.

On-site Insight This means that if you are doing a knock-down and rebuild or large extension with a sizeable amount of demolition work you will need a Waste Management Endorsement from TAMS. For a single dwelling project on a green-fields site you do not have to provide a Waste Management Endorsement.

Part B General Development Controls, Element 7 Services Section 7.2 Servicing and Site Management, Rule R27 Explanation This rule has been deleted to reduce the amount of documentation required to be submitted.

Part B General Development Controls, Element 7 Services Section7.3 Utilities, Rule R28 Explanation A Statement of Compliance from each relevant utility provider has to be provided (water, sewerage, gas and stormwater). If there is no stormwater easement or territory owned pipes within the property boundary a Statement of Compliance is not required to be obtained from TAMS. What this means to you Clearance (Statement of Compliance) from ActewAGL is required for gas sewerage and electrical. Clearance from TAMS is required for stormwater only if there is a stormwater easement or a stormwater main within the block boundaries.

Part C Development Type Controls, Element 4 Parking and Site Access Section 4.2 Parking, Rule R44 Explanation This rule has changed from specifying the maximum width of the garage to the maximum total width of garage door openings and carport widths is 6m or 50% the frontage of the dwelling, whichever is less. What this means to you The total widths of the garage door openings not garages is 6m or 50% of the frontage of the dwelling, whichever is less. This means that if the dwelling is greater than 12m wide you can have a 6m wide single garage door or two 3m wide garage doors.

Part C Development Type Controls, Element 5 Amenity Section 5.2 Private Open Space, Rule R49 c) Explanation The sunlight onto the Private Open Space (POS) requirement has changed. The new requirement is for the POS with a 6m minimum dimension to be situated to the north, north west or north east. Otherwise if it is located to the south, south-west or south-east it should be in a

position that can maintain a minimum of 3 hours sunlight between 9.00 am and 3.00 pm on 21 June. What this means to you If the 6m x 6m POS is located to the north and complies with the rest of the rule there is no requirement to do a shadow diagram. If however it can’t be situated to the north (for example on a north – south orientated block) the 3 hours of sunlight provision must be shown on a shadow diagram.

Part C Development Type Controls, Element 6 Environment Section 6.1 Water Sensitive Urban Design, Rule R51 Explanation This rule has changed to clarify the inclusion of extensions and alterations. All new dwellings as well as alterations and extensions that increase the floor area by more than 50% need to produce evidence that the proposal will achieve a minimum 40% reduction in mains water consumption compared to a house built in 2003. What this means to you This rule has now clarified the size of the extensions and renovations requiring compliance with the water reduction target.

Part C Development Type Controls, Element 6 Environment Section 6.1 Water Sensitive Urban Design, Rule R52 Explanation This rule has been changed so that the plumbing fixtures are 3 star rated not AAA rated. It also changes the roof catchment areas to be connected to water tanks, to comply with this rule. What this means to you For blocks less than 300m2 no tank but 3 star rated plumbing fixtures, for blocks 300–499m2 2,000L tank with 50% or 75m2 of roof connected to tank, 500–800m2 4000L tank with 50% or 100m2 of roof connected to the tank and for blocks greater than 800m2 10,000L tank with 50% or 125m2 of roof area connected to the tank. All the tanks are to be connected to at least the toilet, laundry cold water and all external taps.

Other Amendments The other technical amendments in the revised Territory Plan relate to multi-unit development code and mixed use development code. Should any member need clarification on any proposed rule change, they can contact Eugene at the Master Builders on 02 6247 2099.


On-site Insight Award Winning Training Formula Occupational Health & Safety (General) Regulation 2007 Effective 26 May 2008 If you are in control of a workplace you must take reasonably practicable steps to minimise the risks or hazards. This will include using safe working practices and providing training, instruction or information. To assist members in complying with the new OH&S (General) Regulations the Master Builders have commissioned sets of comprehensive Work Method Statements for key trades and contractors. The Work Method Statements come in hard copy form and with a CD of the statements, plus a free, one hour, face to face induction program. The cost is $110 for members and $550 for Non-members. See the induction dates on the cover of this Onsite Insight or contact the Master Builders on 02 6247 2099 for more details.

MBA Group Training has had a long standing commitment over the years to employing apprentice plumbers. Our plumbing apprentices are trained by CIT and during their last year of training they complete their ‘post trade’ qualification. Most plumbing apprentices commence and finish their trade training with the same employer. As a trade group they have high completion rates and only a small number leave MBA Group Training for private employment. This makes them one of the most stable and reliable sectors of the MBA Group Training operation. This year, Don Rail (Manager Pastoral Services) and Wendy Tengstrom (General Manager Training) attended the annual Master Plumbers’, Drainers’ and Gasfitters’ Association of the ACT 2008 Plumbing Industry Dinner on the 8th May 2008. Gerard Allen, an MBA Group Training plumbing apprentice won the Stage One Plumbing Award for 2008. Wendy commented that it was great to see one of our apprentices taking this award. Gerald is hosted by Custom Plumbing Services, a plumbing business based in Fyshwick which has been a long standing supporter of MBA Group Training.
