The Site Handover Certificate Seems Like a Formality Until You Realise It Is Not

Picture this. You win a contract, sign the agreement, and the client calls you on a Monday morning to say the site is ready. You mobilise your team, bring in your equipment, and start clearing vegetation. Three weeks later, the client's neighbour shows up claiming the boundary cuts through his land. Work stops. A dispute begins. The question of who is responsible for that lost time and who pays for it will eventually come down to one document.

Did the client formally hand over the site to you in writing?

A site handover certificate, also called a site possession certificate, is the formal document by which the employer transfers physical possession of the construction site to the contractor. It is the starting pistol for the construction contract. Under most standard forms of contract used in Kenya, including the Joint Contracts Tribunal (JCT) and the International Federation of Consulting Engineers (FIDIC) forms, the contractor is entitled to possession of the site on or before the date stated in the contract. If the employer fails to give possession on that date, the contractor is entitled to an extension of time and, in many cases, compensation for the costs of delay.

Without a signed handover certificate, none of that protection exists in a form that is easy to enforce.

Consider a second scenario. You are a contractor on a school project in Kisumu. The contract start date passes, but the county government is still clearing some residents from part of the site. You are told verbally to start on the free sections. You do. Four months later, the county is claiming your works are delayed and threatening to apply liquidated damages. Your defence is that you never had full-site possession. The county's position is that you started work willingly. The handover certificate, or the absence of one, is where that argument ends.

The document itself does not need to be complicated. A properly executed site handover certificate should record the date possession was given, identify the extent of the site being handed over, note any areas excluded from possession and the reasons why, confirm that the site has been cleared of encumbrances that would prevent the contractor from starting work, and be signed by both the employer or their representative and the contractor. In FIDIC Red Book contracts, the engineer typically issues the site possession notice on behalf of the employer.

The date on the certificate is critical for two reasons. First, it establishes the commencement date from which the contract programme runs. If the contract allows 52 weeks for completion and possession is given two weeks late, a contractor who does not have a signed handover certificate recording that late possession starts the clock from the wrong date and may find themselves penalised for a delay they did not cause.

Second, it establishes the point at which the contractor takes responsibility for the site. Before handover, the employer is responsible for the condition of the site, including any existing structures, utilities and third-party encumbrances. After the handover, that responsibility transfers. A contractor who begins work without a formal handover is effectively accepting responsibility for conditions they have not been formally given authority to control.

The third scenario is perhaps the most common in Kenya's private sector. A contractor begins work on a residential development in Nairobi. No handover certificate is signed because the client and contractor have an informal relationship, and both parties consider the paperwork secondary to getting started. Midway through construction, a dispute arises over payment. The contractor stops work. The client argues that the contractor abandoned the project. The contractor argues the client is in breach. In the absence of clear contractual records, including a site handover certificate establishing when works formally commenced, the dispute becomes harder to resolve and more expensive to litigate.

The fix is straightforward. Before mobilising any team, equipment or materials to a site, a contractor should insist on receiving a signed site handover certificate. If the employer or their architect is reluctant to issue one, the contractor should write a formal letter confirming the date they took possession and the condition of the site at that time, and keep a copy. Photographs of the site condition on the day of handover, time-stamped and filed, add a further layer of evidence.

Kenya's National Building Code 2024, which came into effect on March 1, 2025, reinforces the importance of formal documentation across the construction process. The NCA registers all construction projects and tracks compliance through the project lifecycle. A contractor whose project records are in order, including a signed site handover certificate, is in a significantly stronger position in any dispute that reaches the NCA, an adjudicator, or a court.

The handover certificate is one page of paper. What it protects is worth considerably more.
