Request
Please could I request a full list of all the sub-contractors/suppliers that are involved on the M25 junction 28 improvements.
These details can be found in the health & safety documents (which is a requirement by law), if you cannot locate the details in house can you please request them direct from the Principle Contractors as they are covered under F.O.I as the principle contractor working on behalf of a government body and it is therefore deemed that any information they hold in relation to this project is held on your behalf.
