Starting with drawings before decisions

Many projects begin with a request for plans, but the real questions are still open: budget, use, market, approval route, team, delivery model and risk.

When those decisions are late, drawings become revisions instead of progress.

Ignoring the total development cost

Construction cost is only part of the story. Professional fees, approvals, statutory costs, contingency, finance and time all affect viability.

A project can be buildable but not viable. That is why the early check must include both design and numbers.

Not creating a usable brief

A good brief is not just a wish list. It captures decisions, assumptions, constraints and next actions. It lets professionals price and advise properly.

REDM’s capture step exists to turn free checks into a project file when the client is ready.

Next step

Turn this insight into a project decision

Use the free check or calculator while the question is still fresh. If the numbers make sense, continue into report delivery, capture and project setup.
