Special Inspections

Special Inspections

UAE Fire Code and International Building Code mandate inspection of firestop systems to achieve required fire-resistance rated construction and compartmentation. The inspection shall be conducted  in accordance with ASTM E2174 for through penetrations and ASTM E2393 for fire resistive joints & perimeter barriers.

Special Inspections are required for most facade systems globally. UAE Fire Code calls for strict compliance and mandates inspection of facade systems by an IAS AC291 accredited special inspection agency to ensure that flame spread on exterior facade is restricted.

The local AHJ and International Building Code require that the fireproofing inspection agencies have the experience, equipment and competence i.e. personnel able to perform such inspections. This is to ensure that the required fire-resistance rating for structural steel or other construction type are achieved. 

Sprinklers are designed to contain the spread of fire. A compliant design will only perform once installed and commissioned as per the design intent. During our decades of expertise inspecting FLS systems, we have found that most failures occur due to wrong installation. To ensure the installation will perform its intended function, 3rd party inspections are vital. The idea that “more is not always better” applies perfectly to sprinkler systems. We perform sprinkler inspections to ensure design compliance, installation verification, and functionality.

Standpipe systems are commonly used nowadays. Whether dry or wet, firefighter and rescue personnel have enforced the provisions of standpipe systems. Standpipes are used to support manual firefighting by delivering water to confined areas of a building. Highrise or high-depth buildings could have confined spaces which would be difficult to reach. Inspection during construction will ensure these provisions will perform and help in the firefighting and rescue operations.

75% of the death during fire incidents are due to smoke/toxic gases. Smoke control or management systems are designed to prohibit smoke from entering stairwells, means of egress, elevator shafts or similar areas. These systems are often ignored during design and not installed correctly. Major issues will arise during commissioning when the designed parameters are not achieved. We provide inspection services to the project stakeholders not only to comply with the design but also to ensure that the tenable conditions will be maintained during fire or emergency evacuation.

Fire doors and opening protectives are pre-eminent in the fire compartmentation. These are required for not only fire resistance during a fire but also to ensure operation during daily activities. The correct type at the correct location, required ratings (i.e. F, T & L ratings), and tested/listed components are few areas to examine. Our experienced inspector can verify these provisions and advise the stakeholders on the best possible solutions to save lives and the constituted costs.
