1. Reading Construction Drawings & Redlining
Construction Plan Drawings means only those different types of drawings specifically entitled as such and listed in the Specifications or in any Addendum, or any drawings furnished by the Commissioner, pertaining or supplemental thereto. The four stages of the life cycle of a working construction drawing set— conceptual, schematic, design development, issue for tender contract drawings and Issue for construction drawings — enables contractors, subcontractors and construction managers to make informed decisions, manage risks, control costs, and ensure that projects meet their objectives ( Law Insider & LinkedIn)
Contractor’s Drawings Review Mark-ups (Or Redline Mark-ups) of the tender/ contract drawings and specifications that have been printed or in PDF format to the drawings symbols and images, and marked up for errors, omissions, changes, and revisions. The markups are typically done in red ink to make them easier to find, hence the name Redline Drawings. The contractor then issues RFIs to the Architect and design team to clarify and resolve the discrepancies, which later may be issued as a Change order to the project (Young Architect).

2. Constructability Reviews, RFIs & Change Orders
16.1 A Construction Constructability review is an independent and structured review of construction bid documents by construction professionals to make certain that the work requirements are clear, the documents are coordinated, and that they assist the contractor in bidding, construction and project administration to result in reduced impacts to the project (CMAA).
Construction Request for Information (RFI) is a business process used in construction to request clarification about documents, drawings, specifications, or other project conditions (Procore).
Construction Change Order Process (CO) is a document used to alter the original agreement on a construction project. It details the changes in the scope of work, cost, and schedule that are required. In many instances, the construction contract dictates the change order process (Procore).
