Sustainability and Ecology
Sustainability
• BREEAM ‘Excellent’ targeted
• All electric building, no gas
• 19% improvement on Building Regs Part L• Heating and Cooling recovery systems• Rainwater harvesting • Sustainable drainage and attenuation • LED lighting and Air Source Heat Pumps (ASHP)• 20kWp of photovoltaic (solar) panels on the roofs• Mechanical ventilation and airtightness (windows are not openable
and therefore further mitigates heat/ cooling loss)• Blackout blinds and shading to minimise solar gain through glazing• Good quality and recessed glazing to minimise solar gain • Lifecycle analysis and Carbon Embodiment study has been
undertaken• Minimisation of C02 emissions and pollution • Lifespan and flexibility/ building functionality and consideration of
climate change• 100% electric charging provision for the public car park
Ecology:
• Green roof and bio-diverse planting
• Planting to complement improvements to air quality
• Fragrant and bee friendly planting in the courtyard (publicly
accessible)
• A bee hotel nesting bees
• Insect towers on the roofs
• Bird nesting boxes
Project Update
• Site investigations and ground water and gas site monitoring (6 months) were completed in 2020. 6 boreholes and reference made to 20 number boreholes from records within 250m of the study site boundary. The engineers have confirmed that the results have showed nothing of concern;
• The tender has been completed and Gilbert-Ash have been formally engaged as the Main Contractor;
• Site setup, enabling works and early archaeology are planned to commence October 2021;
• This will require relocation and reduction of some ground floor car park facilities;
• No car park closure until January 2022;
• Main project works and demolition planned to commence January 2022.

CFA PilingContinuous Flight Auger (CFA) Piling
The use of CFA piling is constructed with partial soil removal by drilling. This generates
lateral soil compression. It is a lower vibration technique and is considered to be
beneficial over driven piles and has a higher pile capacity than piles using bentonite
slurry.
Once the depth of the pile has been achieved with the drill concrete is injected and the
drill is withdrawn and concrete is filled into the required depth with a reinforcement cage
in place.
The drill is then cleaned and the rig can proceed to the next location.
Secant piles are constructed so that there is an intersection of one pile with another.
Secant piling is undertaken by a ‘hit and miss’ pile approach where every other pile
location is undertaken and then the infill piles are revisited later. The secant pile concrete
wall forms a structurally robust and waterproof perimeter to the ‘basement box’.
Secant walls are utilised to transfer lateral, vertical or a combination of both loads
through weak soil layers to a suitable bearing layer. They can be drilled in all types of
configurations that can form an interlocking watertight wall and provide a structural
overlapping wall.
