Construction Project Manager and Principal Designer Insurance

This is the part of the role most often taken on casually and it deserves to be understood on its own terms rather than as another line in an appointment.

Under CDM the principal designer plans, manages and monitors the pre-construction phase, coordinates health and safety, and ensures designers comply with their duties. It is a duty holder role created by regulation, so it is not something a contract can transfer away by describing somebody else as responsible. If something goes wrong on site and the HSE investigates, they will look at what was actually done: whether risks were identified, whether designers were coordinated, whether pre-construction information was provided and whether it reached the principal contractor.

Two practical points. Make sure the role is named on your insurance schedule, because a policy written for project management may not contemplate a statutory duty holder role. And keep the evidence of performing it rather than only the appointment that gave it to you: the risk register, the designer coordination, the information issued and when. An appointment proves you held the role; the records prove you discharged it.

Project management claims are won and lost on documents, and the single most valuable document is a record of a client decision taken against your advice.

Clients compress programmes, cut contingency, value engineer specifications, instruct early starts before design is complete, and appoint contractors on price. Each of those is their decision to make and each of them increases risk, and when the consequence arrives the recollection of who recommended what becomes remarkably fluid. A project manager who can produce a note saying a phased handover was recommended and a single completion date was instructed is in a completely different position from one who cannot.

None of this needs formality. A short written summary after a meeting, sent to the client, recording what was recommended and what was decided, is sufficient and takes minutes. The habit matters more than the format, and it is worth doing consistently rather than only when something feels risky, because the decisions that cause trouble rarely feel risky at the time.

As with any advisory role, the client appointment is signed first and decides how much exposure the policy is being asked to carry.

Four clauses matter most here. An uncapped liability, where nothing limits exposure. A cap above your indemnity limit, which looks like protection and is not. The absence of a net contribution clause, which exposes you to the whole of a loss that designers and contractors contributed to rather than your share. And any promise about a completion date or a final cost, which converts professional judgement into a warranty sitting outside cover.

Add collateral warranties, which give funders, purchasers and tenants a direct route to you, and obligations to maintain cover for a stated period after practical completion, commonly six or twelve years. That last one is a real financial commitment continuing long after the fee is spent, so it should be priced into the fee rather than discovered later. All of these are routinely amended before signature and essentially never afterwards.

Project managers are frequently drawn into claims that are really about somebody else's work, and understanding why helps in managing it.

When a project goes wrong, a client looks at everybody they appointed. The designer is blamed for the design, the contractor for the build, and the project manager for not having managed either properly: not identifying the design was late, not pressing the contractor, not reporting the risk, not administering the contract correctly. So the claim against you is frequently secondary and arrives alongside others, which is one reason net contribution matters so much.

It also means your value as a defendant is in the record of what you reported. Regular written progress reporting, a maintained risk register, and documented instructions and certificates are the things that distinguish a project manager who managed a difficult project from one who presided over it. In an adjudication those documents are read closely, and their absence is itself treated as evidence.

Almost everything here is professional indemnity and the appointment, not the policy. We are an FCA regulated broker and will not tell you we are the best choice. These are the questions that decide it.
