About the Project
Built on the plot of an old community centre, this new-build school faced considerable risk with the construction of a new community centre alongside it. With delays in the centre’s construction raising the spectre of blockages on his scheme’s site access road, Ed Dwight acted fast. He presented the client with three viable alternatives for resolving the looming difficulties. The choice was made, and the project got under way with the deadline for the pupil intake in the coming academic year derisked.
Ed then delivered programme and cost certainty by proving that the projected power demand could be serviced by the local grid. This eliminated the need to install a new electricity substation and the associated infrastructure.
His power calculations were based on the introduction of a range of energy-efficient appliances and systems. They included daylight sensor-based lighting and natural ventilation and heat recovery that employed ‘peak lopping’ to allow a reduction in the size and power of the fan units.
And when the project moved from a summer to a winter steel-frame installation, he protected his cost and programme gains by finding a way to spray fire-protection paint onto the frame on site. By deploying temporary sheeting and heating, he was able to bring the cold-rolled steel-frame sections up to a temperature that would still allow the fire protection to perform.
