The building team
Client, architect, quantity surveyor, structural engineer, contractor, sub-contractors, clerk of works and the local authority building inspector.
Planning and programming
Bar (Gantt) charts, critical path networks, site layout planning (storage, access, welfare), and resource scheduling.
Estimating and bills of quantities
Measure quantities from drawings (m, m², m³, number), apply unit rates, add preliminaries, contingencies and profit.
Worked example: A wall 12 m long and 3 m high (half-brick thick) needs about 55 bricks per m². Bricks cost US$0.12 each, and mortar and labour add US$4.50 per m². Estimate the cost.
Area = 36 m²; bricks = 1 980 → 237.60; mortar and labour 36 × 4.50 = 162.00; total ≈ US$399.60
Contracts and procurement
Tendering (open, selective, negotiated), contract types (lump sum, measure-and-value, cost-plus), retentions and defects liability periods.
Regulations and approvals
Plans approved by the local authority under the Model Building By-laws and planning regulations; stage inspections (foundations, DPC, roof, drainage); occupation certificates. Health and safety on site (NSSA requirements).
Sustainability and innovation
Green building, local and low-cost materials (stabilised soil blocks), energy efficiency, waste reduction, and alternative building technologies for affordable housing.
