Engineering, construction
and commissioning

Ten service lines covering the whole industrial project — the structure, the steel, the power, the pipework, the tanks, the cabins, the machinery and the engineering that ties them together.

Warehouse & Factory Construction

The full industrial envelope, from the ground up. We have built production warehouses with spans to 60 metres and eaves heights to 18 metres, and we understand the difference between a shed and a building that has to carry cranes, conveyors and a wash-down floor.

Pad, strip and raft foundations designed to the actual ground conditions
Ground-bearing and suspended reinforced concrete floor slabs
Steel portal frames and structural steelwork, fabricated and erected
Blockwork, cladding, roof sheeting and rainwater goods
Factory and warehouse roof repair on operating plants
Loading bays, aprons, hardstanding and external works

01 / Warehouse & Factory Construction

Steel Structures — Design, Fabrication & Installation

Portal frames, trusses, platforms and support steelwork. Analysed and detailed in-house, cut and welded to drawing, primed, then craned into position and plumbed on prepared bases. The structural backbone of every warehouse we put up.

Structural analysis and member sizing for portal frames and trusses
Connection design, fabrication drawings and cutting lists
Workshop fabrication, welding and protective priming
Holding-down bolt setting to template and base plate grouting
Craneage, erection, plumbing and alignment of frames
Purlins, side rails, bracing, cladding and roof sheeting

Gas & Diesel Generator Installation and Commissioning

Complete industrial power installation, taken all the way through to a running set. We have installed and commissioned units from 1,080 kVA to 1,500 kVA, including a 1,250 kVA industrial gas generator at Mercury Mills, Ota, with all the civil and mechanical work that surrounds them.

Reinforced concrete generator bases and radiator bases
Generator house construction, ventilation and acoustic treatment
Exhaust systems, mufflers and stack support steelwork
Water line, gas line and fuel line installation and connection
Cable routing, containment and termination coordination
Load testing, alignment and full plant commissioning

Gas & Gasoline Pipeline Fabrication

Industrial gas and gasoline pipework, from the meter or the tank farm through to the burner or the dispenser. We fabricate, install, support and test lines that run through operating plants and live depots, which means the work is planned around your shift pattern rather than the other way round.

Pipe spool fabrication to isometric drawings
Headers, manifolds, reducers and branch connections
Valve stations, isolation points and instrument tappings
Pipe supports, hangers, guides and anchor design
Routing through live plant with permit-to-work discipline
Pressure testing, purging and connection to plant equipment

Gas trainsGasoline linesValve stationsPressure testing

Transportation & Positioning of Heavy Plant

Getting a 1,500 kVA generator into a building that was not designed for it is an engineering problem, not a haulage problem. We plan the route, the lift, the access opening and the final placement — including removals from cramped generator houses that were built around the set.

Loading, rigging and securing of generator sets and heavy plant
Low-loader transportation nationwide and across West Africa
Site access surveys, temporary works and structural opening design
Precise positioning, skating and final placement on base
Removal and relocation of existing sets from confined plant rooms
Reinstatement of openings, bases and finishes after placement

Industrial Machinery Installation

Production equipment is only as accurate as the base it sits on. We cast, level and grout machine foundations, set anchor bolts to template, and support your equipment supplier through alignment and commissioning.

Reinforced concrete machine bases and inertia blocks
Anchor bolt setting to supplier templates and tolerances
Levelling, shimming and epoxy grouting
Weighbridge foundations — including 80-tonne installations
Access platforms, walkways, handrails and ladders
Alignment checks and commissioning support

Storage Tanks & Underground Diesel Storage

Gas, fuel and water storage tanks fabricated and installed above ground and below it. Underground diesel storage is a structural problem as much as a containment one — a deep excavation, braced formwork, heavy reinforcement, watertight construction and a top slab that carries whatever is driven over it. We build the whole thing.

Deep excavation, dewatering and temporary works to the tank chamber
Braced timber and steel formwork to walls and chamber sides
Heavy reinforcement to walls, base slab and load-bearing top slab
Watertight concrete, tanking and waterproof membranes
Diesel, gas, water and effluent treatment plant (ETP) tanks
Fill, draw-off, vent and gauge pipework, bunding and containment

Porta Cabin Design, Fabrication & Installation

Prefabricated site offices, guardhouses, control rooms and welfare units built from insulated sandwich panel on a steel base frame. Single storey through to two-storey units with external stairs and balconies, set out and erected on site in days rather than months.

Insulated sandwich-panel wall and roof systems
Steel base frames, floor decks and external stair access
Single and two-storey cabin configurations
Site offices, guardhouses, control rooms and welfare units
Electrical first fix, lighting and air-conditioning provision
Delivery, craneage, setting out and levelling on prepared bases

General Building Construction

Administrative blocks, offices, commercial and residential structures — delivered with the same structural rigour we apply to industrial work. Setting out through to finishes, with building-control compliance handled as part of the contract.

Site clearance, setting out and level control
Substructure: excavation, blinding, bases, ground beams and DPC
Reinforced concrete frames, columns, beams and suspended slabs
Blockwork, roofing, screeding, plastering and finishes
Mechanical and electrical first and second fix coordination
Statutory inspection and building-control liaison

Structural Design & Detailing

The service that sits underneath every other one. We model, analyse and detail structures in-house — column and beam schedules, reinforcement design, bar bending schedules and full working drawings — so the build is resolved on screen before it is resolved in concrete.

Structural analysis and modelling of framed buildings
Column, beam, slab and foundation design
Reinforcement detailing and bar bending schedules
Steel connection design and fabrication drawings
Working drawings, sections and construction details
As-built records and drawing issue for statutory approval

Scope

Not sure which of these you need?

Most of our projects cross several service lines at once — a factory extension that also needs a new generator base and a gas line re-route. Send us the scope and we will tell you what it actually involves.
