there are same but:
shop drawing :
1- we do it before construction the project
-2 contain all detail to be help in construction in site and procurement phase
3- we need it for all projects
4-material in drawing should be as owner requirements and design
as built drawing :
1- need after construction ( if any item done in site , it should be surveyed and done in drawing )
2- mostly need for public projects like banks, commercial project and all projects that will be need easy maintenance
3- mostly we don`t need details , because we delivered in shop drawing
4- all material in drawing should be as execution
5- as built contain all modifications that required in site
Shop drawings and as-built drawings are two types of drawings used in the construction industry, but they serve different purposes and are created at different stages of a project. Here's an overview of the differences between the two:
Shop Drawings:
1. Purpose: Shop drawings are detailed drawings created by contractors, subcontractors, or manufacturers to illustrate how a specific component or system will be fabricated, installed, or constructed. They provide specific information about the dimensions, materials, installation methods, and other relevant details.
2. Timing: Shop drawings are typically produced during the pre-construction or construction phase of a project before the actual fabrication or installation begins.
3. Accuracy: Shop drawings are highly detailed and specific to the particular project. They are typically based on the design drawings, specifications, and other project requirements. They need to be accurate and precise to ensure proper fabrication and installation.
4. Scope: Shop drawings focus on individual components or systems, such as structural elements, mechanical systems, electrical systems, or specialized equipment. They may include detailed information about connections, dimensions, tolerances, finishes, and other technical aspects.
5. Review: Shop drawings are submitted to the architect, engineer, or project owner for review and approval. The purpose of the review is to ensure that the proposed fabrication or installation methods comply with the design intent and meet the project requirements.
As-Built Drawings:
1. Purpose: As-built drawings, also known as record drawings or redline drawings, are created after the completion of a construction project. They document the actual conditions of the project as built, including any modifications or changes made during the construction process.
2. Timing: As-built drawings are generated towards the end of a construction project, typically after all the construction work has been completed and before final project closeout.
3. Accuracy: As-built drawings reflect the actual construction conditions, including any variations or modifications made during construction. They serve as a record of what was built, capturing any deviations from the original design and providing an accurate representation of the completed project.
4. Scope: As-built drawings cover the entire project, documenting the final layout, dimensions, configurations, and relationships between various components and systems. They may include revisions, additions, or deletions made during construction.
5. Use: As-built drawings are used for future reference, maintenance, and renovation purposes. They provide an accurate representation of the project as built, helping with troubleshooting, modifications, or expansions that may occur later on.
In summary, shop drawings are created before construction to illustrate how specific components or systems will be fabricated and installed, while as-built drawings are produced after construction to document the actual conditions of the completed project.
If you want to get more detailed blog here I have one reference for you on Difference between shop drawings and as build drawings.
Shop drawing is approved detailed drawing for construction. As built drawing is the reflecting actual constructed on Site.
Le dessin technique permet au fabriquant de la pièce de lire et comprendre comment usiner avec précision cette pièce. Le dessin bâtiment permet à l'entrepreneur ou le maçon d'exécuter l'ouvrage comme décrit sur les plans.
A shop drawing shows how the building is originally designed--where the electrical wiring, plumbing, everything is supposed to go. However, during construction, a lot of contractors don't follow the plans and specs very well, or plans get changed in mid-stream. So as-built drawings show how the building actually turned out. My father is an architect, and I recently had to mark up the shop drawings of their cabin to show what wiring actually went to which switches and which outlets. It was incredible to see the differences.
