The redline drawings include importantly the items mentioned on the list as follows but not limited to: Log of Redline Markup Drawings shall be prepared by Construction Department and validated by QC Department. This is a continuing process that is being implemented and updated during the project duration by the Construction team with thorough knowledge of how the marking is being prepared.Ĥ. Changes on the site shall be marked with “RED” color on the controlled copies. The construction team will take the controlled copyof approved drawings and will stamp it with the “Redline” stamp in the “green” (or whatever color propose to be used in stamping but will stand out different from the approved drawing stamp color).ģ. The redline marking process starts and based on the approved activity on-site raised through an inspection (i.e. Record drawings, also known as “as-built” drawings, accurately represent what was built and are used for future work or reference.ĭetailed steps taken in the flowchart are as follow:Ī. The record drawings are then created using red-lines. The contractor will “ red line” the drawings showing the modifications at the end of the project. For example, structural drawings were made at the start of a new construction project. The words “red line” usually refer to the red pen used to mark changes to the drawings by hand. The “red-line” is being kept and updated by the Construction Team and the “As Built” submission where the reflected redline markup is being done by the Engineering Team or Technical Team designated by the contractor’s project organization.Ī red-line drawing is a form of intermediate drawing that reflects modifications or corrections to a previous drawing. This describes the process, roles and responsibilities, requirements, records to be maintained, and approval of redline drawings.
As-built documentation is created after the construction of a structure is finished. The building models are created by physically measuring the built asset in order to provide Computer-Aided Design (CAD) or Building Information Modeling (BIM) documentation. High-precision 3D laser scanners are employed to measure the physical space, as well as a variety of as-built software asto sketch and model the built environment. ? As-Built Modeling ServicesĪn as-built model depict a structure or a place in the state in which it was actually completed.
After the initial phase of the project is completed, the preparation and use of construction drawings become necessary. They represent the exact depiction of the project as it was completed. In order to accommodate some specific and unavoidable challenges that arise during the construction process, the GC makes essential revisions to the original plans and specifications of the project.Īs-built plans show all of the alterations, whether minor or major, made by the contractor to the original documents in order to provide an exact representation of the project. An as-built drawing is a construction drawing generated and submitted by a general contractor after the project has been successfully completed.
