CAT 3 checks are required on complex, unusual or high hazard situations to increase the safety and effectiveness of designs and reduce the risk of temporary works failure.
Andun Engineering Consultants (Andun) provide independent BS5975 compliant Cat III checks for the construction industry. Our team have an excellent track record of performing CAT III checks on a variety of different schemes particularly in railway and nuclear environments.
Cat III checks are performed by our team of specialist temporary works designers; engineers that understand the checking process and needs of the project.
CHECKING TEMPORARY WORKS
The checking of temporary works is split into four categories under BS5975 from CAT 0 through to CAT 3. The correct checking category for a temporary works design is defined by the complexity and scope of a project, this also determines who can perform the check.
A Cat 3 or CAT III check is required when a temporary works design is complex, unusual or in a high hazard location; such as a nuclear environment or works adjacent to a railway.
ADDING VALUE TO CAT 3 CHECKS
Andun add value to Cat III checks by ensuring that our findings are not presented as pass/fail.
Instead our team review projects and provide comprehensive feedback on the validity of the design. Our engineers, where appropriate, raise issues and work with the designer to resolve queries, while maintaining the requisite level of independence.
Where appropriate, we may suggest design changes that will deliver a benefit to the overall project team. Recommendations are based on project safety and design efficacy. The CAT III check may also identify potentially less labour intensive solutions or savings by using alternative materials.
CAT 3 CHECK EXAMPLE
An example of this, would be a crash deck that Andun were tasked to CAT III check, where we suggested a change from two layers of scaffold boards running on top of each other to two layers running perpendicular to each other.
This improved the load spread and reduced the likelihood of rubble punching through the crash deck. This had no impact on cost or erection timescales but enhanced the safety of the design.
