As-built drawings are to be under the control of one single person managing the access to the drawings.As-built drawings are to be kept on site at all times during the construction process.If that’s the case, you can ask the AEC of record to provide you with a sequential number according to the drawing set and use the same scale and legend as the one used in thru original design. Sometimes it will be necessary to add sheets to the drawings.This will facilitate the as-built completion and will reduce mistakes. Add all notes within a specific sheet in one single drawing.Some drawing and design details must be stamped and sealed by whoever did the external design.Be consistent on the date location to make sure everyone is aware of the revision date. Make sure that all drawings are dated after the red-lines are complete.Every note and document must have stamped time and date identifying when the note was added to the drawing.Provide photos and information from all obstructions in the area.Underground utilities shall have elevation, material type, ground cover, depth, diameter, and flow direction if needed.If speciality equipment is installed by other contractors, clearly identify that information as part of the as-built drawings.All new equipment and material used, must contain location specification, sizing, material type and other pertinent details.If the contract allows, add fabrication, erection, installation, and shop drawing information to the as-built.Then write down the new value and encompass it with a cloud to demonstrate the change. As-built drawings must include revised dimensions by crossing out or using an “X” to write over the original dimension. Do not delete or remove original dimensions and measurements.If you need to draw and add detailed design information, it is recommended to use the same scale in the as-built as the original design drawing scale.Avoid using words like similar, equivalent and replace them with the right and detailed information that is part of the equipment installed in the project.They are not ultimately responsible for changes during the installation process or field directives. Don’t expect that the architect or designer will stamp and sign the drawings. The following recommendations are suggested for better managing as-built drawings:
