Site Inspections
 
Many site  visits are straightforward  - just a paper-chase so that someone with sufficient experience can confirm to Building Control that all is in order. All products can be shown to be properly tested or assessed and installed correctly. This can involve testing intumescent paint or sprayed fire protection thicknesses   

However, some sites have some unusual design details.....

On this site we have a flexible fire barrier penetrated by power cables, cables on trays, steel pipes, walkways and doors!!

None of these details can be realistically tested, so we have to make an assessment of each product combination based on the way we can expect them to interact.

Its no good to install a heavy steel door into a plasterboard partition!
