Design–build contractors, Accra

Design–build you can schedule around.

We put the architect, the trades and the inspectorate under one programme — so scope, budget and hand-over date stop moving after the first pour.

Bonding capacity, in cedis

Our record is the argument. From high-rise offices to motorway structures, we hand over buildings that are still doing their job a decade later — and we can show you the ones we finished before the date said so.

How we work

From brief to hand-over

01

Discovery & scope

We walk the site, read the drawings you already have, and write down what is in the contract and what is not.

02

Estimate & programme

A priced bill against a dated programme — materials, labour and prelims separated so you can see what moves.

03

Permits & safe plan

District assembly permit, EPA screening where it applies, and the site safety plan lodged before mobilisation.

04

Build & QA

Weekly look-aheads, photographed progress, cube tests and a snag list that is open to you the whole way through.

05

Final walk-through

Joint inspection, as-builts and O&M manuals handed over, and the ten-year structural warranty starts.

Testimonials

Built right. Backed by our clients.

KM

Kwabena Mensah

Head of operations, Pelican Foods

They handed over our 4,200 m² cold store three weeks before the date in the contract, and the snag list was eleven items long. Nobody on our side has worked with a contractor like that before.

5.0

NA

Naa Adjeley Asare

Facilities director, Ridge Hospital Trust

Building next to a working out-patient department is a scheduling problem before it is a construction one. They planned around our clinics rather than asking us to plan around them.

5.0

YB

Yaw Boateng

Managing partner, Sankofa Estates

Three blocks, one programme, one set of valuations that always arrived on the Friday. The finish quality is the reason we have given them the next phase without going back out to tender.
