Updating: Construction drawings are only used during the construction process and are not typically updated, while as-built drawings are updated as the building changes over time to reflect its current state.

Accuracy: Construction drawings are based on the design plans and may include some assumptions or estimates, while as-built drawings should be as accurate as possible, they are based on the actual physical characteristics of the building or structure.Audience: Construction drawings are primarily used by contractors, builders, and construction workers to build the project, while as-built drawings are used by the building owner, maintenance staff, and building authorities for reference, compliance, and future use.Timing: Construction drawings are created before construction begins, while as-built drawings are created after construction is complete.As-built drawings, on the other hand, include information on the actual physical characteristics of the building or structure, such as the location of walls, doors, windows, and other features, as well as the location and details of electrical, plumbing, and mechanical systems.
