 This process also gives the architect and sub-consultants the opportunity to select colors, patterns, and types of material that were not chosen prior to completion of the construction drawings.This is not an occasion for the architect to select different materials than specified, but rather to clarify the selection within the quality level indicated in the specification and quantities shown on plans.For materials requiring fabrication, such as reinforcing steel and structural steel, the architect and engineer need to verify details furnished by the fabricator as well as the required quantities are met.
