Design · Installation · Maintenance · Compliance
We design, install and maintain fire protection in line with regulations, and keep every facility ready for its next inspection.
Our vision
Our mission
We design, install and maintain fire protection in line with regulations. Our codified engineering system lets a few experts do the work of many; with our licence and app we reach every facility that must renew.
What we do
One contractor answers for all four, so nothing falls between the designer, the installer and the maintainer.

Each has its own hazard and its own limits on when work can happen. We start from both.

Working with us
No step starts before the previous record is signed. Each has a named owner on our side, so you always know who answers for it.
Operating system
Estimating, project control, procurement, maintenance and compliance run on one digital system, led by a team that has automated more than thirty processes for a Saudi industrial group.


Automated engineering services according to NFPA, Civil Defense and the Saudi Building Code.
Installation projects, from won deal to handover.
Unified document control system.
The field mobile app for partners and technicians, and the dispatch module.
The mobile app for subscribers.
Our management system for quality, health, safety and environment.
Who we are now
Management that has built and run EPC, fire protection and industrial services companies in Saudi Arabia, and led a global group’s fire, security and building automation business in the Kingdom.
These are projects from earlier roles. They are the team’s own record, not APPCO’s.

Get in touch
We read the fire scope and come back with clarifications before we price. Tell us about the project here and it goes straight to our sales engineers, who answer within one working day.
This is an automated assistant. It can be wrong, and it cannot agree prices or dates.
