Preconstruction & Feasibility
Numbers you can plan a scheme around before spending on design.
What this service covers
Preconstruction and feasibility work is about giving a client a defensible view of cost, programme and constructability at the earliest possible stage — before design fees start to accumulate and before commitments are hard to reverse.
We produce order-of-cost estimates aligned to RICS NRM1, options appraisals that compare schemes on a like-for-like basis, and viability assessments that stress-test a project against realistic build cost, professional fees, contingencies, finance and profit. Our benchmarking uses BCIS data anchored to real recently-completed West Sussex projects — coastal Worthing extensions carry different assumptions to a Horsham new build, and our figures reflect that.
For developers, we produce residual valuations that inform land bids. For homeowners, we translate architect concepts into realistic total-cost figures so nothing is a surprise at tender. For institutional clients, we produce cost plans robust enough to sit inside a board paper.
Typical deliverables
- Order-of-cost estimate (RICS NRM1 aligned)
- Options appraisal and comparative cost report
- Viability assessment / residual valuation
- Cash flow forecast
- Risk register with cost impact
