From substations to combined cycle plants, MAO Contractors delivers heavy civil works, security, and turnkey EPC across West Africa and beyond.
A contractor built for the long, heavy work.
MAO Contractors is an integrated builder of industrial infrastructure. We engineer, procure, and construct facilities that power factories, light cities, and keep operations running through the harshest conditions. Our crews are sized for the work, our equipment is owned, and our supervisors stay on site from groundbreaking through commissioning.
The firm was built on a single principle. A contractor should answer for the whole building, not just their slice of it. That belief still runs the company, from how we organise our crews to how we sign our contracts.
Self-performed civil, structural and finishing works for industrial, commercial and institutional projects. We hold the master schedule, manage subcontractors, and carry the safety record. Clients get one number to call, and one signature on the certificate of completion.
Site protection that is engineered, not improvised. We provide vetted guard forces, access control, perimeter design, surveillance integration and 24 hour command room operations for energy, mining and manufacturing facilities. Every contract is tied to a documented response plan.
Engineering, procurement and construction under one contract and one schedule. Our in-house engineering, long-lead procurement desk and self-perform construction teams remove the seams that delay typical multi-vendor projects. We sign on price, scope, and date, and we deliver against all three.
Large scale generation projects, from open and combined cycle gas plants to solar farms, hybrid plants and high voltage substations. We have placed concrete for boiler houses, erected turbine halls, set transformers, pulled HV cable, and seen first synchronisation on plants ranging from 30 MW to 600 MW.
A contractor that owns its mistakes and finishes its work. The kind of partner you want on a 400 megawatt plant that has to be online before the dry season.
Site clearance, mass earthworks, deep foundations, RCC structures and concrete batching.
Fabrication, erection and connections for turbine halls, pipe racks and process buildings.
Boilers, HRSGs, turbines, pumps, compressors, vessels and large bore piping.
HV switchyards, transformers, cable laying, earthing systems and protection.
Field instruments, control panels, DCS interfacing and loop checking.
Vendor management, expediting, customs clearance and oversize cargo handling.
Pre-commissioning, performance testing, punch list closure and reliability runs.
Integrated HSE plans, permit to work, manned guarding and surveillance operations.
235 MW combined cycle gas turbine plant. MAO delivered full EPC including civil works, mechanical erection of two GT units and one ST unit, HV substation and balance of plant. Achieved first fire 11 days ahead of schedule.
Foundations, internal roads and 33 kV collection network for 18 turbines across a 92 hectare site.
Turnkey delivery of mounting structures, modules, inverters, MV network and the 132/33 kV evacuation substation.
Heavy duty pavement, 14,500 sqm warehouse, weighbridges and a four lane truck park for a major cement major.
New AIS substation including two 60 MVA transformers, control building and integration with the existing 132 kV grid.
We sit with your team, walk the site, and pressure test the brief against site conditions, regulatory constraints and supply realities. You leave with a feasibility memo, not a sales pitch.
Our in-house engineers produce FEED level drawings, a procurement plan, a level 3 schedule and a fixed price proposal. One document, one set of assumptions, one accountable signature.
We mobilise our own equipment and supervisory crews. Site offices, HSE controls, security and laydown areas are set up before the first concrete is poured.
Weekly progress against the baseline, daily HSE walks, third party inspection on critical welds and concrete pours. No surprises in the monthly report.
System by system commissioning, punch list closure, operator training and a structured handover pack. We stay on site through reliability runs.
Send the brief, the constraints and the deadline. We will come back inside seven working days with an honest read on scope, price and schedule.
