Management of Construction Disputes in Nigerian Federal Contracts: Procedures and Outcomes

Construction dispute resolution in Nigerian federal contracts involves complex interactions between contractual dispute resolution clauses, the Public Procurement Act 2007 framework, and the practical realities of public sector contract administration. This study examines dispute management procedures and outcomes in Nigerian federal construction contracts. A professional investigation methodology was adopted, reviewing 30 federal contract dispute cases from project documentation obtained from the Federal Ministry of Works, the Infrastructure Concession Regulatory Commission, and the Bureau of Public Procurement. Interview data were gathered from 25 contract lawyers, claims engineers, and federal procurement officers. Dispute causes, resolution methods, timelines, and outcomes were analysed. Results indicate that variation order value disputes are the most common dispute category (39 percent), followed by extension of time claims (27 percent) and material cost escalation claims (21 percent). Mean dispute resolution time through contract dispute boards is 14 months, compared to 38 months for arbitration and over 60 months for litigation. Early dispute resolution mechanisms are underutilised, with only 18 percent of cases resolved through negotiation within 90 days. The study recommends mandatory Dispute Adjudication Boards on all federal contracts above 2 billion naira, standardised variation order valuation procedures, and a Federal Contract Dispute Resolution Protocol to reduce the proportion of disputes escalating to formal arbitration.
