Category 2 & 3 Design Checking
We offer Category 2 & 3 design checking across all externally produced temporary works schemes. With our extensive temporary works design experience, we can confidently identify designs that will succeed, and those which require modification to be compliant.
For a Category 2 check we will require the original design brief, drawing and calculations, and will provide a check certificate upon completion with recommendations on compliancy as necessary.
For a Category 3 / Third Party Check we only require the design drawing and design brief, and we will undertake independent calculations to verify the design. A check certificate along with accompanying calculations will be produced, with comment as required.
We have a track record of undertaking CAT 3 checks for large schemes and complex temporary works, as well as completing Network Rail and London Underground design compliancy forms.
To help identify your requirements, please see the checking categories table as set out in BS5975:2019.
