BA Hons, Year 3, Project 1

Newcastle’s City Image:

Strengths:

•There is a huge section of space that could become a new section of public realm

•There are multiple options for where to extend

•There is already a really strong cultural presence with the theatre and museum opposite

•The site is in the west of the city – a historically neglected part of the city

Weaknesses:

•St. James’ Boulevard is a huge urban edge cutting the site off from the city centre

•The boulevard creates lots of noise pollution and air pollution

•Too much hardscaping and not effective planting for biodiversity

•The existing fabric of the building will have to be upgraded in terms of thermal performance

•The party wall of the building will have to be considered very carefully to eliminate thermal bridging

Opportunities:

•The boulevard could be closed down over time and this could create yet more public realm

•Availability of sun and wind on site could be used to generate electricity and heat water

•If I extend to the north there is an opportunity to create a new sense of frontage for Blandford Square

•There is an opportunity to connect with the Newcastle Helix site and maybe be a small business hub

Threats:

•If the boulevard is closed down, there is a risk of city-wide congestion

•If the extension is to the west here is a risk of overheating in summer

•There is potential that the are could become gentrified – therefore the community will be the decision makers

•If the new landscaping is not carefully considered the impact of the new tree species etc could cause consequences later down the line

2 - PPE Storage

3 - Toilet Block

4 - Canteen/ Mess

5 - HSE Office

6 - Meeting room

7 - Plant

8 - Secure lock up

TCR - Tower Crane - 35 boom

TH - Turning head

CP - Car park

W - Water mains connection

P - Power mains connection

A - Carpentry workstation

B - SIP storage/ prepartion area

C - Stick system curtain wall station

Ancillary

On-site Health and safety principles:

• Every worker on site must be provided with the adequate PPE before commencing work, this will be provided in the PPE store on site and the workers will have a changing facility on site.

• Before setting foot on site, each worker must have the relevant training and be signed off by an examiner – for a example a relevant CSCS Card for the activity they will be undertaking etc (Construction Builder Support [CBS], 2021)

• The removal of the existing windows and the floor plate as well as the extension build means that there will be a number of workers working at height i.e. 2m or more. These workers will be equipped with the appropriate fall protection – i.e. harnesses, fall nets, tool retention lanyards etc.

• Repetitive strain injuries can have a big effect on a workforce, yet they are some of the easiest injuries to avoid. Therefore, the handling of heavy components on site will be carefully monitored – no person should be lifting more than 10kg worth of weight at once. This applies to loads over 10kg too, for example a 30kg weight would require 3 workers.

• Construction is generally a dangerous industry and there are inherent risks attached to that fact. Therefore, there will be some hazards that can’t be fully eliminated. However, the risk can be mitigated and should be carefully considered to minimise the potential for harm as much as possible.

Risks that cant be fully eliminated will be mitigated by providing sufficient safety measures to reduce the likelihood of accidents. For example: provision of break spaces to prevent fatigue, implementing the relevant health and safety signs, and having a HSE on site that will ensure operations are running safely and in line with the health and safety principles outlined above.

PPE Provision:

The provision of the correct PPE is of paramount imporatnce for protecting workers. All of the following standards (below) are derived from SHE PPE: Complete guide to Personal Protective Equipment unless stated otherwise (SHP, 2022)

• Hard hats - The relevant standards are BS EN 397 and BS EN 14052

• Steel toe caps - The relevant standard for safety footwear is BS EN ISO 20345.

• Hi-vis clothing – The relevant standard for hi vis clothing is BS EN 471 + A1.

• Ear defenders - The relevant standard for the ear protectors is BS EN 352 Part 1.

• Safety goggles - The relevant standards are BS 7028 (Guide to Selection of Eye Protection for Industrial and Other Uses) and BS EN 166 (Specification for Eye Protectors).

• Gloves - BS EN 388 covers the specification

Fall Nets:

Due to the fact tha tthe proposal removes a part of a floor plate top open up a space in the existing building, there would have to be a sufficient net installed to prevent not only falling workers being injured, but materials and tools wouldn’t fall on others below.

Site compound: of gloves against mechanical hazards.

The Portakabins comprising the site compound have been arranged in a stacked configuration in order to reduce the overall footprint without comprising the facilities.

• Dust mask – there will be different standards of respiratory protection required for different tasks.

• Knee pads – knee pads and other body protection carry different standards and aren’t necessarily required – therefore workers may choose to not wear them however they would be provided on site.

• Safety harness – the different fall retention equipment will have different associated standards and will have to be thoroughly checked on a regular basis to ensure it is in working order.

Hammerhead tower crane (30m Boom):

The tower crane has a large enough boom to be able to reach ver the extension and existing building. It is also large enough to swing over the new public realm and site compound to move elements directly from HGVs or from the floor.

HGV Drop off Point:

Access for HGVs is essential for a smooth and seamless construction process. This has been positioned so that it is in the centre of the site as well as having a good connection to the road. The crane has a suffieciently long boom arm so that it can move components from the HGVs to a designated part of the site compound or lift them directly into the building.

Scaffolding:

Scaffolding is a key part of any construction project - this will allow for a temporary platorm for the removal of the existing windows as well as making the installation of the new windows and SIPs easier.

Temporary balustrade:

The partial removal of the existing floorplate would mean that there would need to be a temporary balustrade installed prior to the construction and installation of the new railing. This would be installedas soon as the floorplate has been removed along with the fall nets.

There has not been sufficent space left for a wheelchair refuge - the core would have to be redesigned.

The size and complexity of the floor plans of this building means that it will require an automatic fire detection system. This system will be primarily concerned with the protection of life as opposed to property. Despite the public nature of this building, a phased exit strategy would not be appropriate. The installation of an automated system would also eliminate the reliance on manual systems or staff operated systems. This would vary across the different types of spaces in the building so as to best prepare for the consequences of a fire in each specific space.

The stair case meets the width requirement for a building of 4 storeys with less than 270 people during a simultaneous evacuation (1000mm)

The systems installed across the building would be: L3 – systems designed to warn of fire at an early enough stage to enable all occupants, other than possibly those in the room where the fire started, to escape safely before the escape routes become impassable because of fire, smoke or toxic gases. – in compliance with BS 58391.

• Most single story, contained spaces (e.g. offices and studio spaces) would be fitted with a point heat system

The fire detection method would vary across the building to suit the spaces:

• The larger atria would have to be fitted with a Aspirating Fire Detection system as the high ceiling heights would rule out the effectiveness of a point heat system

• The larger atria would have to be fitted with a Aspirating Fire Detection system as the high ceiling heights would rule out the effectiveness of a point heat system

• The plant room would be fitted with an infrared early fire detection system alongside a high-pressure mist system that would be capable of effectively suppressing a fire from the large pieces of machinery etc.

The LVL frame structure will naturally char and build a layer around it that will protect it from fire. As this material is consistent and has a predictable char ratethe beams can be oversixed to give a suitable fire proof time of 120 minutes - this will be sufficient time to allow for evacuation and arrival of the firefighting team.
