As built and Shop drawings are important types of drawings during project implementation. Each type of drawing has its own purpose and application for the project. There are several types of drawings like construction drawings, shop drawings, architectural drawings, Structural drawings, MEP drawings, concept drawings, as-built drawings, etc. In this article, we will learn about the concept and difference between as built and shop drawings
What Are As Built Drawings?
As-built drawing is a drawing of a completed work or construction part. Show actual dimensions compared to design dimensions, made on the basis of approved construction design drawings. As-built drawings are drawings that record all the details of actual items and works performed.
As-built drawings are created to reflect the change between the built work and the original design. It also includes detailed construction items like the original drawings.
As-built drawings are the basis for performing warranty and maintenance work as well as repair and renovation later: repair electricity, groundwater, repair and replace a part of the work.
What Are Shop Drawings?
Shop drawing is the most detailed construction drawings for on-site construction. Based on the technical design drawings along with the technical specification of the project provided by the investor, the contractor will deploy shop drawings for his construction items and submit them to the investor for approval.
Depending on each contractor and discipline, there are many types of Shop drawings:
- Shop drawings for construction
- Shop drawings for MEP
- Shop drawings of steel structure
- Shop drawings of tiling items
- Shop Drawings drywall ceiling
- Shop drawings of indoor lighting electrical items,…
Shop Drawings are necessary work to be completed before entering construction at the site. Nowadays, with the support of software and especially 3D BIM construction information models, the implementation of shop drawings becomes easy with absolute accuracy.

Difference Between As Built And Shop Drawings
If the construction is complete and there is no difference from the original design, we can use shop drawings as as-built drawings. But if the construction is different from the original, we must create as-built drawings.
Creating this as-built drawing is extremely important. It helps owners know the current status, confirm the actual location of the work items after repair and maintenance. This is also a prerequisite document to complete the work of performing the acceptance test of the work, paying the contractor, completing the completion procedures.
Legally, as-built drawings are the basis for the management work of State agencies. It helps to determine if the work was carried out exactly according to the building permit.
We will list some of the differences between as built and shop drawings in the following table:
| As Built Drawings | Shop Drawings | |
|---|---|---|
| Purpose | Reflect the change between the built work and the original design. | The exact volume of materials and equipment for the project, as well as the parameters of the accompanying materials and equipment for the construction work. |
| Uses | Know the current status, confirm the actual location of the work items after repair and maintenance. Acceptance test of the work, paying the contractor, completing the completion procedures. | Deploy construction work outside the construction site |
| Execution time | After on-site construction | Before on-site construction |
Conclusion
We can clearly recognize the difference between as built and shop drawings. In short, both types of drawings above are extremely important in construction.
