How We Built a Heavy Steel Apartment Building in Africa in 45 Days
A 45-day apartment programme is not about rushing. It is about moving work from the site into the factory, sequencing deliveries precisely and giving the installation crew a structure that fits together the first time.
Planning the programme backwards
We started with the handover date and worked backwards: commissioning, finishes, facade, structure, shipping and fabrication. Each milestone was assigned a responsible party and a latest-start date.
Local approvals and site preparation ran in parallel with factory production, so the foundation was ready when the first steel arrived.
Fabrication in a controlled environment
The heavy steel frame was cut, drilled, welded and trial-assembled in our factory. Connections were numbered, and every beam was packed in the order it would be erected. Bathroom pods, wall panels and staircase units were finished before loading.
Factory inspection caught dimensional issues before shipment, where correcting them would have cost days.
Shipping and site logistics
The shipment was split into three deliveries: primary frame, secondary steel and enclosure, then finishes and services. A local crane and a crew of twelve worked a single shift, with our engineer on video calls each morning.
The frame was topped out in eleven days. Enclosure and internal works followed, and the first apartments were ready for occupation at day 45.
What made the difference
Three factors drove the result: a complete design package before fabrication, a disciplined delivery sequence, and a local contractor who understood the installation drawings. Heavy steel apartments are fast when the preparation is thorough.
