Construction Sub-Contract Agreement (Ghana)

A Construction Sub-Contract Agreement in Ghana sets out the rights, duties and consideration binding the parties to it.

Construction sub-contracting in Ghana is governed by the Contracts Act 1960 (Act 25), which provides the general legal framework for contractual obligations in Ghana, including the formation, performance, and breach of contracts. Section 1 of the Contracts Act 1960 (Act 25) codifies the essential elements of a valid contract: offer, acceptance, consideration, and contractual capacity. All construction sub-contracts in Ghana must satisfy these requirements to be legally enforceable before the courts.

The Public Procurement Act 2003 (Act 663) and the Public Procurement (Amendment) Act 2016 (Act 914) regulate sub-contracting arrangements on publicly funded construction projects in Ghana. Where the main contract is a government contract procured through the Public Procurement Authority (PPA), the main contractor must obtain prior written approval from the employer (a government entity, district assembly, or metropolitan authority) before sub-contracting any substantial portion of the works. The PPA sets thresholds above which sub-contracting must be disclosed and approved.

The National Construction Authority (NCA) established under the National Construction Authority Act 2011 (Act 820) regulates the construction industry in Ghana. Section 3 of Act 820 requires contractors and sub-contractors to be registered with the NCA and classified in a category appropriate to the nature and value of the works they undertake. A sub-contractor working on a project in Ghana must hold a valid NCA registration certificate in the relevant category (civil works, mechanical, electrical, plumbing, etc.) before commencing works. Sub-contractors who are not NCA-registered risk prosecution under Act 820 and may be denied participation in public procurement processes.

The Factories, Offices and Shops Act 1970 (Act 328) and the Labour Act 2003 (Act 651) impose health and safety and employment obligations on sub-contractors working in Ghana. The sub-contractor is the employer of its own workers and must comply with Act 651 regarding wages, working hours, and leave, and must register workers with the Social Security and National Insurance Trust (SSNIT) under the National Pensions Act 2008 (Act 766). Health and safety obligations on construction sites in Ghana are enforced by the Department of Factories Inspectorate under the Ministry of Employment and Labour Relations.

The Construction Sub-Contract Agreement (Ghana) must be distinguished from a labour-only sub-contract (where the sub-contractor provides labour but not materials), a supply contract (for materials only), and a nominated sub-contract (where the employer or architect nominates a specific sub-contractor under the main contract).

The legal framework governing the Construction Sub-Contract Agreement (Ghana) in Ghana draws on several key statutes and regulatory bodies. Under the Companies Act 2019 (Act 992), the Registrar General's Department (RGD) maintains the register of Ghanaian companies. Section 7 of the Companies Act 2019 governs company incorporation. The Ghana Revenue Authority (GRA) administers corporate tax under the Income Tax Act 2015 (Act 896). The Commercial Division of the High Court in Accra adjudicates business disputes. The Ghana Investment Promotion Centre (GIPC) regulates foreign investment under the GIPC Act 2013 (Act 865). Parties executing a Construction Sub-Contract Agreement (Ghana) in Ghana should confirm the document reflects current law, including any amendments enacted since the original drafting date. The Contracts Act 1960 (Act 25) sets the foundational requirements.

A Construction Sub-Contract Agreement in Ghana is required in the following circumstances.

A Construction Sub-Contract Agreement is needed whenever a main contractor appointed under a principal building contract in Ghana wishes to delegate a defined portion of the construction works — such as electrical installations, plumbing, tiling, roofing, or steel fabrication — to a specialist sub-contractor. Without a written sub-contract, the main contractor has no enforceable mechanism to hold the sub-contractor to programme, quality standards, or payment arrangements.

A Construction Sub-Contract Agreement is required on all public sector construction projects in Ghana procured through the Public Procurement Authority (PPA) where the main contractor intends to sub-contract any part of the works. The Public Procurement Act 2003 (Act 663) and its 2016 Amendment (Act 914) require prior approval from the employer before sub-contracting and specify the information that must be disclosed about the proposed sub-contractor, including their NCA registration details.

A Construction Sub-Contract Agreement is needed when engaging a specialist NCA-registered sub-contractor for mechanical and engineering (M&E) works, including electrical wiring, plumbing and drainage, HVAC (heating, ventilation, and air conditioning), or lifts and escalators in commercial buildings in Accra, Kumasi, or other urban centres in Ghana. The NCA category of registration determines the maximum contract value the sub-contractor is eligible to undertake.

A Construction Sub-Contract Agreement is required when a foreign construction company acting as main contractor on a major infrastructure or commercial project in Ghana wishes to engage a local Ghanaian NCA-registered sub-contractor to satisfy local content obligations under the Ghana Investment Promotion Centre Act 2013 (Act 865) and any applicable sector-specific local content regulations.

A Construction Sub-Contract Agreement is needed when the main contractor requires the sub-contractor to provide a performance bond or retention money guarantee from a bank licensed by the Bank of Ghana, as these instruments require the underlying sub-contract to be in writing and executed before the bond can be issued.

Parties in Ghana should execute a Construction Sub-Contract Agreement before the sub-contractor mobilises to site. Allowing a sub-contractor to commence works without a written agreement creates uncertainty about scope, price, and responsibility for defects, and may prejudice the main contractor's claim under the principal building contract if the employer raises defects attributable to the sub-contractor's work.

A valid Construction Sub-Contract Agreement in Ghana under the Contracts Act 1960 (Act 25) and the National Construction Authority Act 2011 (Act 820) must contain the following essential elements.

Parties and NCA Registration: Full legal names of the main contractor and the sub-contractor, their NCA registration numbers and categories, and their principal places of business. Both the main contractor and the sub-contractor must hold valid NCA registration certificates in categories appropriate to the works before execution of the sub-contract.

Scope of Sub-Contracted Works: A precise description of the sub-contracted works, including reference to drawings, specifications, bills of quantities, and any nominated work instructions forming part of the main contract. The scope must be defined clearly enough to avoid disputes about what is included and excluded.

Sub-Contract Price and Payment: The sub-contract price in Ghana Cedis (GHS), whether lump sum, measured, or cost-plus, the payment schedule tied to progress milestones or monthly valuations, the retention percentage (typically 5% to 10%) and the conditions for release of retention on practical completion and expiry of the defects liability period, and the procedure for interim payment applications and certification.

Programme of Works: The start date, the sub-contractor's programme tied to the main contract programme, key milestone dates, and the consequences (including liquidated damages) for delay caused by the sub-contractor.

Defects Liability: The defects liability period (typically 12 months from practical completion of the sub-contract works), the sub-contractor's obligation to remedy defects notified during the defects liability period at no additional cost, and the procedure for issuing a defects liability certificate on expiry of the period.

Health and Safety: The sub-contractor's obligation to comply with the Factories, Offices and Shops Act 1970 (Act 328), to maintain a safe working environment on site, to provide personal protective equipment to its workers, and to report accidents to the Department of Factories Inspectorate.

Insurance: The sub-contractor's obligation to maintain contractor's all-risk (CAR) insurance and public liability insurance throughout the sub-contract period, with minimum limits specified in the agreement.

Termination: Grounds for termination by the main contractor (including material breach, insolvency, and persistent failure to meet programme), grounds for termination by the sub-contractor (including non-payment), and the consequences of termination including payment for work done and return of materials.

Governing Law and Dispute Resolution: Ghana law, with disputes referred to the High Court (Commercial Division) in Accra, or to adjudication or arbitration under the Alternative Dispute Resolution Act 2010 (Act 798) administered by the Ghana Arbitration Centre.
