The workforce is a delivery constraint
Conventional building depends on skilled trades whose capacity takes years to expand. Recruitment, apprenticeship completion and the loss of experienced workers all affect the available workforce.
A larger budget does not immediately produce more qualified people. A delivery plan must show how work gets done with the skills available during the programme, alongside the time needed to train new entrants.
Change the work as well as the headcount
Factory cutting and repeatable assembly move structural tasks into controlled production. Standard components support familiar workflows, consistent inspection and repeated learning. Less work on an exposed site also reduces weather disruption.
The change has limits. Kitchens, bathrooms, services and finishing still require competent people. A credible programme accounts for those trades and schedules them across sites. Manufacturing reduces part of the workforce constraint; the remaining work still needs delivery capacity.
Procure a dependable production model
The Trust specifies the home’s performance and a price, then tenders for delivery. WikiHouse demonstrates the reference approach. Other builders and manufacturing systems compete against the same requirements.
This connects the construction method to the affordability case. A lower headline material cost is insufficient without reliable completion, quality and a maintainable home. Production capacity, contractor resilience and the standard of the finished building belong in the delivery assessment together.
