Expert insights, industry news, and helpful guides from the Bomay Group team.
Choosing the right contractor is the most important decision you will make for your construction project. Here is what to ask.
The construction industry in Nigeria has both exceptional professionals and problematic operators. Knowing how to distinguish between them before you sign a contract can save you enormous time, money, and stress. Here are the critical questions every client should ask.
**1. Are you registered with the Council for the Regulation of Engineering in Nigeria (COREN) or the Architects Registration Council of Nigeria (ARCON)?** Reputable construction professionals maintain professional registrations. These bodies enforce standards and provide a recourse if problems arise.
**2. Can I visit a current or recently completed project?** Seeing finished work — and speaking to previous clients if possible — is the most reliable indicator of quality. Be cautious of contractors who cannot facilitate site visits.
**3. What is your payment structure?** Legitimate contractors use milestone-based payment structures tied to construction progress. Be very cautious of any contractor demanding full or majority payment upfront.
**4. Who will be on site daily?** Large contractors often assign junior supervisors to day-to-day management. Know exactly who is responsible for your project.
**5. What are your quality assurance processes?** Good contractors use specified materials, maintain records of all materials used, and have clear quality checking procedures at each construction stage.
At Bomay Group, we welcome all of these questions and can answer every one with evidence.
The quality of your building materials determines the quality of your finished structure. Here is an expert guide.
One of the most consequential decisions in any Nigerian construction project is the selection of building materials. The Nigerian market offers a wide range of options at very different quality and price points. Here is what you need to know.
**Cement.** The foundation of any concrete structure. In Nigeria, Dangote, BUA, and Lafarge are the most reliable brands. Avoid purchasing from unknown sources, as adulterated cement is unfortunately common. Use the correct grade — typically 42.5N for structural concrete.
**Blocks.** Sandcrete blocks vary dramatically in quality across Nigeria. Specify the appropriate mix ratio (typically 1 part cement to 6 parts sand for standard blocks) and test block strength before accepting delivery. Consider interlocking compressed earth blocks for eco-friendly and cost-effective construction.
**Roofing.** Long-span aluminium roofing sheets are popular for their durability and resistance to the Nigerian climate. Specify the correct gauge — thinner sheets may be cheaper but flex and fail faster.
**Steel Reinforcement.** Use only certified deformed bars from reputable manufacturers. The use of substandard rebar in columns and beams is a significant structural risk.
**Finishing Materials.** Ceramic tiles, paint, and plumbing fittings vary widely in quality. Invest in quality for these visible elements — they determine the aesthetic and durability of your finished space.
Bomay Group uses only specified, quality-assured materials on every project, with records maintained for transparency and accountability.
How long does it actually take to build a house in Nigeria? Here is a realistic timeline for each phase of construction.
One of the most common frustrations in Nigerian construction is unrealistic expectations about timelines. Clients often expect construction to be faster than it realistically can be, while some contractors overpromise and underdeliver. Here is an honest guide to construction timelines.
**Phase 1: Design and Documentation (4-8 weeks).** Architectural drawings, structural engineering plans, and MEP (mechanical, electrical, plumbing) designs must be completed and approved before construction begins. Rushing this phase leads to costly changes during construction.
**Phase 2: Regulatory Approvals (4-12 weeks).** Building plan approval from the relevant local government or urban development authority is legally required. Timelines vary significantly by location.
**Phase 3: Foundation and Substructure (2-4 weeks).** Site clearing, setting out, excavation, and foundation construction. Timeline depends on soil conditions and foundation type.
**Phase 4: Superstructure (8-16 weeks).** Column casting, block laying, slab casting, and roofing. This is the longest phase for most residential buildings.
**Phase 5: Mechanical, Electrical, and Plumbing (4-8 weeks).** Electrical conduits, plumbing pipes, and MEP rough-in works before plastering.
**Phase 6: Finishing (6-12 weeks).** Plastering, tiling, painting, fixtures, fittings, and external works.
**Realistic Total:** A typical 3-bedroom bungalow in Nigeria takes 9-18 months from design to handover. A 4-bedroom duplex typically takes 12-24 months. Any contractor promising significantly faster completion should be questioned carefully.
