A promising site is not automatically a deliverable project. Effective feasibility work tests the commercial case and the delivery conditions together, before assumptions become commitments.
Begin with the decision, not the design
The first task is to define the decision the feasibility study must support. That may be whether to acquire a site, proceed to planning, revise a brief or commit further design expenditure. A clear decision frame prevents teams from producing detailed analysis that does not answer the commercial question.
Agree the target use, quality, programme, return expectations and risk tolerance at the outset. Where these are uncertain, develop a small number of credible scenarios rather than one apparently precise answer built on weak assumptions.
Test the site and planning position
Review title, access, utilities, neighbouring uses, environmental conditions, heritage, rights of light and other physical or legal constraints. Planning policy should be assessed alongside the likely route to consent, stakeholder interests and the evidence needed to support an application.
Constraints are not always reasons to stop. They are inputs to design, cost and programme. The value of early diligence is understanding their combined effect while there is still room to respond.
Connect cost, value and programme
Development cost, anticipated value and programme must use consistent assumptions. Inflation, abnormal works, professional fees, finance, contingency and operational transition are common areas of understatement. Sensitivity testing should show which assumptions have the greatest effect on viability.
A programme is credible only when it reflects approvals, procurement, design maturity, site logistics and market capacity. A shorter programme is not more useful if it cannot be delivered.
Finish with an actionable recommendation
A strong feasibility report makes the recommendation, conditions and next actions clear. It identifies what is known, what remains uncertain, who should resolve each issue and when the next investment decision should be taken.
KEY TAKEAWAYS
What to carry forward
Define the investment decision before starting analysis.
Assess commercial, planning and delivery assumptions as one system.
Use scenarios and sensitivities where evidence is still developing.
End with named actions, owners and decision gates.
