Engineering the infrastructure that powers Nigeria.
From process plants and power networks to towers and towns, Connexxion Engineering plans, builds and maintains the assets your operation depends on.
An engineering partner that treats your asset like its own.
Connexxion Engineering is the engineering arm of Connexxion Group, a diversified African holding company headquartered in Abuja. We bring together civil, electrical, mechanical and telecom disciplines under one contract, so you deal with a single accountable team instead of coordinating five contractors.
Our engineers work from first principles: understand the site, design to recognised standards, build with disciplined quality control and hand over assets that are documented, tested and ready to be maintained. Where clients want a long-term partner, we stay on to operate and maintain what we build.
Eight disciplines. One team.

Every Connexxion project starts with a documented safety plan, a clear programme and a quality inspection regime. We do not treat these as paperwork. They are how we protect your people, your budget and your reputation.
A clear path from first call to long-term support.
You always know what stage your project is at, what it costs and who is responsible. Here is the path most projects follow.
