This document outlines the process for revising construction drawings and involves 6 main steps: 1) Consultants issue a request for variation to cost consultants, Turner, and the client for approval. Cost consultants analyze costs which takes 10 days for approval. 2) Once approved, consultants issue architectural instructions to contractors and release drawings to Turner for stamping, which takes 2-3 days. 3) Consultants then upload the stamped drawings and transmit to the main contractor, taking 1-2 additional days. Hard copies of the full-size drawings are also provided to contractors over 5 working days.
