Compare all 7 project-type options

Each row uses GEC's default assumptions for that project type (not your edited overview inputs) with a neutral score of 3/5 on the judgement-based criteria, so the comparison is apples-to-apples. Ranked by overall feasibility score - the highest-ranked option is highlighted.

Methodology & source

How the numbers are calculated

Base cost = Extent × Units × Rate.
Pre-tender escalation compounds the base cost monthly over the pre-tender period.
Construction escalation compounds again over the construction period.
Professional fees are applied to the fully-escalated construction cost.
Total investment = escalated cost + fees + land/acquisition, then VAT is added.

Scoring matrix weights

Capital Cost Efficiency 20% · Affordability/Development Margin 20% · Programme/Time-to-Market 15% · Cost & Escalation Risk Exposure 15% · Buildability/Delivery Complexity 15% · Sustainability/Market Positioning 15%.

Margin and escalation-risk scores are auto-derived from your inputs; the rest are judgement calls you set on a 1–5 scale.
