PILING FOUNDATION COST IN LAGOS —
OME BUILDWAY CONTRACTING LIMITED

WHY LAGOS LAND NEEDS PILING MORE THAN ANYWHERE ELSE IN NIGERIA

Lagos is built on some of the most challenging soil in West Africa. Large portions of the state sit on reclaimed land, swampy terrain, coastal sediment and waterlogged soil that cannot support a pad or raft foundation without proper ground improvement.

If your land sits in any of the following areas, piling is not optional. It is the only safe foundation type:

• Lekki Phase 1 and Phase 2

• Ajah and Sangotedo

• Victoria Island and Eko Atlantic

• Ibeju-Lekki

• Coastal road corridors

• Any land reclaimed from the Lagos lagoon

Skipping piling on weak Lagos soil does not save money. It destroys the entire building investment. Cracks appear first in the walls, then the floors begin to sink, and within years the structure becomes unsafe. The cost of demolition and rebuilding is ten times higher than piling correctly from the start.

A proper soil test before piling tells you exactly how deep your piles need to go and what diameter is required. OME Buildway Contracting Limited handles soil testing and piling together so you get one team responsible for the entire foundation process.

PILE DIAMETER OPTIONS AND WHAT EACH IS USED FOR

OME Buildway Contracting Limited executes bored piling in three standard diameters in Lagos State. The right diameter depends on the load your structure places on each pile, the soil bearing capacity at depth and the number of piles in your pile cap design.

Pile Diameter Common Application Typical Depth Range

300mm Residential buildings 8m to 15m

450mm Standard residential 12m to 20m

600mm Commercial buildings 15m to 30m+

The 600mm diameter pile is the most commonly specified pile diameter in Lagos State. Structural engineers specify 600mm piles for most medium to large buildings on Lagos Island, Lekki and Victoria Island because the weak coastal soil requires larger diameter piles to reach competent bearing stratum at depth.

Pile spacing, pile cap design and number of piles per column are all determined by your structural engineer based on the column loads in your architectural and structural drawings.

WHAT AFFECTS THE COST OF PILING IN LAGOS

Piling cost varies significantly from one site to another. Here are the factors that determine your final piling bill:

Pile diameter: A 600mm pile uses more concrete, more steel reinforcement and more machine time than a 300mm pile. Larger diameter means higher cost per linear metre.

Depth to competent soil: In waterlogged areas like Ibeju-Lekki and coastal Ajah, competent bearing soil can be 20 to 30 metres below ground level. Every additional metre of depth adds cost for concrete, steel cage and rig time.

Number of piles: More piles means the fixed cost of mobilising the rig is spread across more units, reducing cost per pile. A 10-pile job costs more per pile than a 50-pile job.

Concrete grade: Bored piles are filled with structural concrete. The grade specified by your engineer affects cost. C25 and C30 are the most common pile concrete grades in Lagos.

Steel reinforcement cage: The weight of steel in each pile cage depends on pile diameter, depth and structural load. Steel prices fluctuate and directly affect piling cost.

HOW TO DO PILING FOUNDATION IN LAGOS — STEP BY STEP BY OME BUILDWAY CONTRACTING LIMITED

Step 1 — Soil test and foundation design Before any pile is bored, a geotechnical investigation is carried out on your site. The soil test report tells your structural engineer what soil conditions exist at different depths, what the bearing capacity is and how deep piles must go to reach stable ground. Without this report, pile design is guesswork.

Step 2 — Setting out pile positions A licensed surveyor marks the exact position of every pile on your site according to the structural drawing. Pile positions must be accurate because the pile cap and column positions are designed around them. OME Buildway works with licensed surveyors for precise pile setting out.

Step 3 — Boring the pile hole A rotary rig drills a cylindrical hole to the specified diameter and depth. In Lagos, this process can go through multiple soil layers including loose sand, soft clay, stiff clay and dense sand before reaching competent bearing stratum. Water and bentonite slurry are sometimes used to stabilise the borehole walls during drilling.

Step 4 — Installing the reinforcement cage A fabricated steel reinforcement cage is lowered into the bored hole. The cage is made from high-yield deformed bars tied with binding wire at specified spacings. The cage must reach the full depth of the pile to provide structural integrity throughout.

Step 5 — Concreting the pile Structural concrete is poured into the bored hole using a tremie pipe from the bottom up. This prevents segregation of the concrete mix. The concrete grade is specified by your structural engineer, typically C25 or C30 for bored piles in Lagos.

Step 6 — Pile load test After piling is complete, a pile load test is carried out on selected piles to confirm they meet the design load requirements. OME Buildway Contracting Limited conducts non-destructive pile load tests and issues a certified test report for every project.
