Send the drawings, specification, scope, BoQ, tender documents and programme. We return a structured mechanical Tender Intelligence Pack for your estimating team to review.
Designed for mechanical and heat-network contractors, M&E companies, FM teams and specialist subcontractors. A typical first review can be turned around in 24–48 hours once the scope and readable documents are agreed. Enquire first and we’ll agree a transfer method for the documents.
