Cost & value
Cost is where performance ambitions are either protected or quietly deleted. On this project the argument that held the line was life-cycle cost: measures were defended by what they save over decades of hospital operation, not by their capital price.
Every VE round is a test of whether shading depth, plant efficiency and façade quality can be justified. Simulation results were used as the evidence base so that cuts were argued on operating cost, not on drawing appearance.
A hospital runs 24/7 for decades; a small efficiency gain in chilled-water plant repays its premium many times. Framing decisions this way is what kept passive-first design intact.
DfMA, prefabricated bathroom units and prefabricated MEP reduced site labour, rework and programme risk — cost benefits that also show up as quality and durability.
COVID-19 manpower restrictions and supply-chain disruption carried programme and cost consequences; off-site manufacture and a live 4D model cushioned the impact.
Final account movement, VE items lost, and measured operating cost against forecast — all best obtained from the client and cost consultant.
