The Margin Protection Playbook
Why Margin Disappears
Most margin loss is not a cost problem. It is a process problem.
The work was priced correctly. The contract was awarded at a sensible margin. But by the time the final account is settled, that margin has shrunk by three, four, sometimes seven percentage points. The question is where it went.
The answer is almost always the same: variations that were never formally priced, payment applications that were assessed down without challenge, CVRs that showed the problem too late to act, and a final account negotiated from a weak position because the paper trail was thin.
This guide maps each of those failure points and gives you the process controls that prevent them.
What's Covered
Five areas where commercial teams consistently lose margin, and how to close each one:
Margin Erosion Across the Lifecycle
Where it starts and how it compounds
Variation Management
Capturing and pricing every change before it disappears
CVR Discipline
What to measure, how often, and what the numbers mean
Payment Application Recovery
Closing the gap between applied-for and certified
Final Account Strategy
Protecting margin at handover when pressure is highest
"The contractors who protect their margin are not the ones who fight hardest at final account. They are the ones who built their position throughout the project so there is nothing to fight about."
