Fire protection design and drawing approval
Designing and auditing alarm, firefighting, smoke, and evacuation plans and approving them.
The approved drawing is what actually gets built and what gets reviewed at final inspection. We design so approval passes first time and the result is buildable at the estimated cost, without over-design.
Detection and alarm design follows NFPA 72: smoke and heat detector spacing based on ceiling height and airflow patterns, battery load calculations for standby operation, and control panel and notification appliance placement that delivers adequate audibility at every point.
For automatic sprinkler systems we work to NFPA 13: hazard classification, hydraulic calculations proving pressure and flow at the most remote sprinkler, and pump room and water tank design sized for the required duration. The hydraulic calculation is what separates an approved system from a rejected one.
The work also covers smoke control for egress routes and protected stairwells, evacuation plans and signage, and special suppression such as clean agent systems for equipment rooms and foam systems for industrial facilities.
We handle submission and follow the review comments through to approval. Where the reviewing authority raises observations we resolve and resubmit, rather than leaving that as a burden on the project team.
- Detection and alarm to NFPA 72
- Sprinkler networks and hydraulics to NFPA 13
- Smoke control and stairwell pressurisation
- Evacuation plans and signage
- Submission and approval follow-through
The engineering drawings we prepare
Every drawing is delivered with its calculations and specifications, because the reviewing authority approves the calculation before the drawing:
- Detector, alarm panel and notification layouts, with the riser diagram.
- Sprinkler and hose-reel network layouts with the hydraulic calculation.
- The fire pump room and water tank, sized.
- Smoke control and stairwell pressurisation.
- Evacuation plans, escape routes and signage.
- Special suppression: clean agent and foam systems.
Engineering design for commercial buildings
A commercial building — a mall, a showroom, an office tower, a hotel — combines high occupancy, open volumes and fire loads that change from one tenant to the next. Its design therefore starts from occupancy classification and exit capacity, then the sprinkler hazard class, then smoke control for atriums and malls.
We have designed for malls, towers, hotels and showrooms in Khobar, Dammam and across the Eastern Province, and we design for the fit-out changes that come when units are handed to tenants, so that each fit-out does not turn into a fresh approval.
Common questions about this service
Yes. We submit, follow the review comments, resubmit until approved, and issue the final compliance certificate once installation is complete.
