Technical Feasibility and Development Appraisal

Test before you commit

Friel Welch supports clients at the earliest stages of development, validating the technical and commercial viability of sites, schemes and acquisitions before significant time or capital is committed.

Our approach

The questions a planning appraisal does not always ask

We go beyond traditional feasibility studies, testing proposals against the realities of delivery, including structural strategy, building services, fire and building safety requirements, statutory approvals, site constraints, procurement risk, programme and cost certainty. The result is an evidence led appraisal that reduces uncertainty and helps avoid costly surprises later.

Working alongside the Architect and wider consultant team, we challenge early assumptions and sense check project briefs against cost, programme, regulation and buildability. This provides clients with confidence that the proposed development is both realistic and deliverable.

Our technical feasibility and development appraisals bring key considerations into a single, clear assessment, covering site constraints, technical viability, statutory requirements, indicative costs, programme implications and delivery risks.

The outcome is a practical decision-making tool, providing clear recommendations and next steps, enabling clients to proceed, revise or pause a project with confidence.
