Who We Are
TechMEPi Engineering is a professional firm specialising in mechanical, electrical and plumbing building services. From Nairobi, we design, supervise and commission systems for commercial, industrial, hospitality, residential and healthcare projects in six countries.
Led by Eng. Francis Wanjohi, PE, PMP — a Registered Professional Engineer with 18+ years in mechanical building services — we deliver innovative, efficient and reliable solutions that meet international standards.
How We Work
One accountable engineer across every stage. We prove each design digitally before anything is installed.
Requirements, site constraints and feasibility captured against the applicable standards.
Cooling loads, hydraulic calculations and coordinated MEP documentation in Revit and AutoCAD.
CFD airflow studies and BIM clash detection prove every system before installation begins.
Qualified site supervision keeps workmanship, safety and programme on track through installation.
Systems are tested, balanced and commissioned against the design intent before handover.
Planned maintenance and responsive support keep systems performing long after handover.

Engineer-led scoping
New · Project Planner
Choose what best describes your project. We’ll turn it into a focused, pre-filled brief you can send straight to an engineer.
For a new build, early multidisciplinary coordination prevents clashes, protects plant space and gives the cost plan reliable quantities.
Selected Works
A portfolio spanning five sectors and six countries — from city-centre plant rooms to Indian-Ocean island resorts.

Building Systems
We design, coordinate and commission every mechanical, electrical and plumbing service in a building — modelled together in one clash-free schematic. Trace a riser, or open its service.
Six coordinated service risers, one clash-free model. Hover a system to trace its route — tap to explore the service.
Design Technology
We model, simulate and validate every system before installation begins — detecting clashes early, minimising risk and shortening delivery timelines. What we prove digitally is exactly what we commission on site.
Reach
From Nairobi, we design, supervise and commission across East Africa and the Indian Ocean — engineering each building for the environment it lives in.
Leadership
Principal Building Services Engineer & Project Manager
A Registered Professional Engineer with a BEng in Mechanical Engineering and PMP certification, Francis has led MEP design and delivery for 18+ years across every sector we serve. He stays hands-on in the tools — Autodesk Revit BIM, CFD simulation and hydraulic analysis — so the engineer who models your building is the one accountable for it. Fluent in English and Kiswahili.
