Redline drawings are used by engineers to note modifications, clarifications, and corrections on the construction plans during site reviews. These redline drawings shall be used as an assurance tool to differentiate design from construction so that error detection can happen in a timely manner before the errors magnify. Redline review by engineers will allow contractors to implement changes based on accurate and updated specifications which will avoid expensive mistakes. This teamwork enhances communication and delivers the final project compliant with safety standards, building codes, and client expectations.
