Third Party Approval / Category III Checking

When a design is deemed to be complex it is a requirement, under BS 5975 and many authorising bodies, for an independent check to be carried out.

We can facilitate this service in two ways;

CHECK ON A CREATOR DESIGN – If a Category 3 check is required on one of our designs we can send our design externally to another company to obtain an independent set of calculations and a check certificate. We will advise if we feel a Category 3 check is necessary, but this may be a request from yourselves of us.
• CHECK ON A DESIGN YOU HAVE ALREADY HAD PRODUCED – If you require a Category 3 check on a design you have already had produced, then we are here to help. We can produce an independent set of calculations and check certificate to approve the design.
