Project management in construction: what it covers, who needs it, and when to appoint

Walk through the later stages of any unmanaged construction project in Kenya and you will see the same patterns. The contractor is two months behind programme and has not told anyone. The architect has issued three instructions that the contractor has not priced or acknowledged. The QS is waiting for drawings that have not been produced. The client has paid two valuations without receiving a supporting breakdown. Three subcontractors are on site from different trades and are working around each other rather than in sequence.

None of these are unusual. They are the default state of an unmanaged project. They are also entirely preventable — not by working harder or by blaming the contractor, but by having someone in place whose specific job is to coordinate the programme, track costs, manage the consultant team, and ensure that decisions are made before they become crises.

That is what a construction project manager does.

A project manager in construction is the client's representative throughout the project. Their core responsibilities span five areas.

Programme management. The PM produces a master programme before construction begins, with milestone dates for each stage. They monitor progress against the programme weekly, flag delays before they compound, and manage the consequences of changes on the critical path. On a project where the contractor is a month behind but nobody has noticed, the PM is the first person to notice — and to act.

Cost management. The PM tracks the project against the approved cost plan: reviewing valuations before they are certified by the QS, managing the variation budget, flagging cost overruns before they exceed contingency, and reporting the cost-to-complete position to the client monthly. The PM does not replace the QS — the QS certifies quantities and rates — but the PM maintains the overall cost picture.

Quality management. The PM defines quality standards in the contract documents and inspects construction against them. Defective work identified early is rectified cheaply; defective work identified at practical completion is rectified expensively and disputed. The PM's site presence — or their appointed clerk of works — is the mechanism that catches quality issues early.

Risk management. The PM maintains a risk register from feasibility through handover. Soil contamination, contractor insolvency, material supply delays, design changes, adverse weather, regulatory queries — each is assessed, mitigated where possible, and managed transparently rather than discovered.

Stakeholder and communication management. The PM runs the design team meetings, produces the action register, ensures decisions are made within the time available, and reports to the client at agreed intervals. On a project where the architect, QS, structural engineer, MEP engineer, and two specialist subcontractors are involved, someone needs to coordinate this group. The PM is that person.

There is genuine confusion in Kenya about the boundary between the architect's contract administration role and a project manager's role. They overlap but are not the same.

The architect's contract administration covers: issuing architectural instructions, certifying payments against completed work, administering the building contract, managing design changes, and certifying practical completion. The architect's primary professional duty is to the design — their contract administration serves that design through construction.

The project manager's role is broader: it is the client's programme and cost representative, coordinating all consultants including the architect, managing the overall project timeline, tracking total cost exposure across all contracts (not just the main contractor), and acting as the single point of accountability for the project delivery.

On a simple residential project, the architect's contract administration may be sufficient. On a multi-storey mixed-use development with multiple contractors, a complex MEP package, and a client who is not experienced in construction management, a separate PM appointment is worthwhile.

The key test: who is managing the overall project timeline and reporting the cost-to-complete position to the client? If the answer is 'nobody,' the project needs a PM.

The best time to appoint a project manager is at the feasibility stage — before design begins. A PM who joins at feasibility can influence the brief, ensure the programme is realistic, set up the contract framework, and manage the design team from the start. This produces the lowest total cost and the shortest elapsed time.

The second-best time is at design completion, before tendering. The PM can manage the procurement process, evaluate tenders with the QS, set up the construction programme, and establish the reporting structure before a contractor is on site.

The worst time to appoint a PM is after problems have started — after the programme has slipped, after the budget has been exceeded, or after a dispute has emerged with the contractor. Recovering a troubled project is harder, more expensive, and more time-consuming than managing a well-structured project from the start.

Architect Darani provides integrated project management as part of the REDM service model. The PM role is built into the project file from feasibility: programme, cost, risk, and communication management are tracked in the same system as the design and approvals, not in a separate consultant's spreadsheet.

Project management fees in Kenya are not regulated by a single statutory scale — they are market rates. The typical range is 2–5% of the total project cost (construction + professional fees), depending on the scope of the PM service and the complexity of the project.

For a KES 30 million construction project with total project cost (including professional fees and statutory costs) of approximately KES 36 million, a PM fee at 3% would be KES 1.08 million. For a complex multi-contract development, the fee may be at 4–5%.

Monthly retainer arrangements are also used for long-duration projects: a PM fee of KES 150,000–350,000 per month for a full-time representative on a project with an 18–24 month construction programme.

The PM fee is not a cost that adds to the project budget in the way that construction cost does. It is a management cost that reduces other costs: fewer variations, shorter programme, less abortive work, and earlier identification of problems. A well-managed project typically delivers within budget and programme; an unmanaged project typically does not.
