Notes on cost, risk and delivery.

Risk that is not identified early does not disappear. It is priced in by whoever is asked to carry it, and a contractor who cannot see the risk clearly will either price it heavily or price it wrongly. Both outcomes cost the client money.

The work worth doing upstream is unglamorous: confirming what is actually being built, what the ground is like, what the access allows, what approvals are needed and when. Each of those answers moves money between the budget and the contingency, and it moves the risk to whoever is best placed to manage it.

Where a project is tendered on an incomplete picture, the sensible position for anyone about to bid is to qualify the offer clearly and to price the unknowns as provisional. Where a client wants certainty, the answer is usually to spend a little longer on the brief rather than a little more on the contract.

The stages run from strategic definition and the brief, through design and technical design, into construction, then handover and use. Cost advice and design information change character at each step: early stages are about orders of magnitude and options, later stages are about fixed information and commitments.

For a client, the practical value of the map is knowing what to expect, and when. Cost certainty increases through the stages, never before them. Anyone promising a fixed number at stage one, before the brief is settled, is describing a position they cannot hold.

For a contractor or specialist, the map is a way of reading what information should exist at the point you are asked to price. If it does not, that is a conversation worth having before submission rather than after.

For an estate agent, a landlord or a maintenance company, the useful output is a register of the elements of the asset, their condition, and an order of priority for work. That turns maintenance from a series of reactive incidents into a planned programme with a cost attached.

The same information supports decisions well beyond maintenance. Refurbishment, conversion and extension options all start from knowing what is already there, and a condition survey is often the cheapest way to find out whether an option is worth pursuing at all.

Where a building is being bought, sold or revalued, an asset register prepared to that standard travels with it, and saves the same work being paid for twice.
