Buildings & engineering structures
Construction & civil engineering in Douala
From buildings to civil engineering structures, STIS designs and builds your project — from the technical study through to handover.
STIS is not just a works contractor: it is an architecture and engineering practice. We take on your construction project in full, from design through to handover — buildings, foundations and civil engineering structures.
Buildings, houses, foundations, box culverts and other civil engineering structures: we cover both the structural works and the engineering structures themselves. Every project is led by our engineers, based on technical studies and rigorous site supervision.
Our support runs from the project study — feasibility, technical studies, works supervision and inspection — through to handover. Upstream, our earthworks crews prepare the ground; downstream, our steel structures complete the works.

Frequently asked questions
Is STIS a design office or a construction contractor?
Both. STIS is an architecture and engineering practice that also carries out the works: we take your project from the feasibility study and technical studies through to construction and handover.
Do you build box culverts and civil engineering structures?
Yes. Beyond buildings and foundations, we build civil engineering structures such as box culverts. Describe your project and we will draw up a quote for you.
Do you handle works supervision and inspection?
Yes. Our engineers supervise and inspect the site at every stage, from the studies through to handover, to ensure the works comply with the requirements.
