HADSOY Engineering Services Limited delivers mechanical and electrical engineering for building and infrastructure projects across Nigeria. We take a services package from design review through installation, testing and commissioning, and hold it under planned maintenance afterwards.

Where we work
Head office in [city], with project teams mobilised nationwide.
Offices, retail, hotels, hospitals and schools. Full building services packages and fit-out M&E within a main contractor’s programme.
Housing estates, apartment blocks and private residences. Estate-wide distribution, water systems and generator or solar backup.
Federal, state and agency projects. We hold the statutory compliance documents that pre-qualification requires, and can produce them on request.
Plants, terminals, warehouses and factories. Electrical installations, process cooling, fire systems and shutdown maintenance windows.
How a package runs
Six stages in the order they happen. Each one produces a document the next stage depends on.
We review the consultant’s drawings against the actual load, flag clashes between services, and confirm the specification before anything is ordered.
Materials specified, sourced and inspected on arrival. Panels and ductwork fabricated to approved shop drawings.
Site teams working to the programme, with method statements and risk assessments issued before each activity starts.
Every circuit tested, every system balanced, results recorded on sheets the client and consultant sign.
As-built drawings, O&M manuals, test certificates, warranty documents and training for the facilities team.
An optional maintenance contract that keeps the systems performing and the warranties intact after handover.
Due diligence
Most tenders in Nigeria stall on paperwork rather than price. We keep the statutory pack current so a pre-qualification submission can go out the same week it is requested.
Start a conversation
Send the drawings or the bill of quantities and we will come back with a priced package. If the design is not finished, tell us the stage you are at and we will work from that.
