Construction Contract (Kenya)

A Construction Contract in Kenya records the obligations the parties accept and the terms governing their arrangement.

The National Construction Authority (NCA), established under the National Construction Authority Act No. 41 of 2011, is the primary regulatory body for the construction industry in Kenya. Every contractor undertaking construction works in Kenya must be registered with the NCA and must hold a valid NCA certificate in the appropriate category — NCA 1 through NCA 8, with NCA 1 being the highest classification for large-scale national and international projects. The NCA levy of 0.5% of the contract sum is payable by the employer before construction commences, remitted to the NCA, and must be referenced in the construction contract.

Architectural designs for any building requiring planning approval must be prepared by a registered architect under the Architects and Quantity Surveyors Act (Cap. 525), administered by the Board of Registration of Architects and Quantity Surveyors (BORAQS). Structural drawings must be prepared or supervised by a registered engineer under the Engineers Act No. 43 of 2011, regulated by the Engineers Board of Kenya (EBK). Quantity surveying services — including preparing bills of quantities (BOQ) that form the pricing basis of a construction contract — must be provided by a registered quantity surveyor under the same Cap. 525 Act.

Planning permission for any building works that alter the exterior of a property, change its use, or exceed specified dimensions must be obtained from the county government planning authority — in Nairobi, this is the Nairobi City County Government under the Physical and Land Use Planning Act No. 13 of 2019. Building approval from the county engineer and relevant approvals from the National Environment Management Authority (NEMA) for developments with potential environmental impact are prerequisites before construction commences.

A Kenya Construction Contract should be distinguished from a Consultancy Agreement with an architect or engineer (which governs professional advisory services) and from an Independent Contractor Agreement for minor works or labour-only contracts. The Construction Contract covers the full scope of building works — materials, labour, plant, and programme — and typically incorporates industry-standard conditions such as the JBCC (Joint Building Contracts Committee) suite, FIDIC (International Federation of Consulting Engineers) conditions, or the NCA standard form for public sector projects.

The legal framework governing the Construction Contract (Kenya) in Kenya draws on several key statutes and regulatory bodies. Under the Land Act No. 6 of 2012, the National Land Commission (NLC) manages public land in Kenya. Section 56 of the Land Registration Act No. 3 of 2012 governs land transfers. The Environment and Land Court (ELC) has exclusive jurisdiction under Article 162(2)(b) of the Constitution of Kenya 2010. The Land Control Act (Cap. 302) requires Land Control Board consent for agricultural land transactions. The Stamp Duty Act (Cap. 480) imposes duty on property transfers at rates of 2% (rural) and 4% (urban). Parties executing a Construction Contract (Kenya) in Kenya should confirm the document reflects current law, including any amendments enacted since the original drafting date. The National Construction Authority Act No. 41 of 2011 sets the foundational requirements.

A Kenya Construction Contract is required at the outset of any significant building or infrastructure project, and is specifically necessary in the following situations.

A Construction Contract is required when a property owner or developer in Kenya engages a registered NCA contractor to construct a residential house, commercial building, industrial facility, or infrastructure works. Under the National Construction Authority Act No. 41 of 2011, the NCA requires evidence of a written contract and proof of payment of the NCA levy (0.5% of the contract sum) before issuing project registration. Projects commenced without NCA registration expose both the employer and the contractor to fines and the risk of a stop-works order.

A Construction Contract is needed when a real estate developer registered with the lands registry under the Land Registration Act No. 3 of 2012 intends to build on a plot in Nairobi, Mombasa, Kisumu, or any other county and wishes to secure the contractor's obligations on scope, quality, programme, and price before investing the contract sum. Without a written contract, disputes about variations, delay penalties, and defective work are decided by implication — invariably to the disadvantage of one party.

A Construction Contract is required when a contractor registered under the NCA in a specific category (NCA 1 to NCA 8) submits a tender for private or public works and the award is made by the employer. The contract formalises the tender acceptance, converts the contractor's priced bill of quantities (BOQ) into a binding obligation, and establishes the payment certification procedure.

A Construction Contract is needed when the works involve government or county government procurement. The Public Procurement and Asset Disposal Act No. 33 of 2015, enforced by the Public Procurement Regulatory Authority (PPRA), requires all public sector construction contracts to be in writing and to comply with PPRA standard bidding documents.

A Construction Contract is required when the employer wishes to impose liquidated and ascertained damages (LADs) for delayed completion — a contractual penalty clause for delay that must be expressly stated in the written contract to be enforceable before the High Court of Kenya (Commercial Division) or the Nairobi Centre for International Arbitration (NCIA).

A Kenya Construction Contract must include the following core provisions to be enforceable and consistent with the National Construction Authority Act No. 41 of 2011 and Kenyan construction industry standards.

Parties and NCA Registration: Full legal names, BRS registration numbers, KRA PIN numbers, and NCA contractor registration numbers of both the employer and the contractor. The contractor's NCA category (NCA 1 through NCA 8) must be stated. Section 15 of the National Construction Authority Act No. 41 of 2011 prohibits any person from undertaking construction works without NCA registration.

Scope of Works: A precise description of the building or civil works to be carried out, ideally by reference to the architectural drawings prepared by a registered architect under Cap. 525, the structural drawings, and the priced bill of quantities (BOQ) prepared by a registered quantity surveyor — all incorporated by reference as contract documents. Ambiguity in scope is the most common cause of construction disputes in Kenya.

Contract Sum and Payment: The agreed contract sum in Kenya Shillings (KES) and the payment schedule — typically milestone payments tied to the construction programme or monthly valuations certified by the contract administrator. The NCA levy of 0.5% of the contract sum must be noted, confirmed as paid or payable. Section 13 of the National Construction Authority Act requires the levy to be paid before work commences.

NCA Levy: Confirmation that the NCA development levy of 0.5% of the total contract sum has been or will be paid by the employer to the National Construction Authority before work commences, as required under the National Construction Authority (Levy) Regulations 2014.

Construction Programme: A baseline programme (typically in the form of a Gantt chart) showing the key milestones, the agreed completion date, and any sectional completion dates. Liquidated and ascertained damages (LADs) for delay beyond the completion date — expressed as a daily or weekly sum in KES — must be agreed in writing before the contract is executed to be enforceable.

Variations: The procedure for instructing and valuing changes to the scope of works. The contract administrator — typically the architect or project manager — must issue a written variation instruction before any additional work is carried out. Oral instructions without written confirmation have limited enforceability before the High Court of Kenya.

Defects Liability: A defects liability period — typically 12 months after practical completion — during which the contractor must rectify any defects notified by the employer, at no additional cost. A retention sum (typically 5% to 10% of the contract sum) is held by the employer as security for the contractor's defects liability obligations, released in two tranches: 50% at practical completion and 50% at the end of the defects liability period.

Insurance and OSHA Compliance: Requirements for the contractor to maintain all risks insurance (covering the works and materials on site), public liability insurance, and employer's liability insurance under the Work Injury Benefits Act No. 13 of 2007 (WIBA). Compliance with the Occupational Safety and Health Act No. 15 of 2007 (OSHA) is mandatory on all construction sites. The forms-legal.com Kenya Construction Contract template covers all eight elements above in a structured questionnaire aligned with NCA and industry standards.

Governing Law and Dispute Resolution: The contract shall be governed by the laws of Kenya. Disputes may be referred to the Nairobi Centre for International Arbitration (NCIA) under the Arbitration Act No. 4 of 1995 (revised 2022), or to the High Court of Kenya. Many construction contracts in Kenya incorporate a tiered dispute resolution clause: engineer's decision, then mediation, then arbitration.
