Do you belong to the architecture, engineering, and construction (AEC) industry?

If yes then, you might have inevitably faced a situation wherein the final version of engineering drawings and drafts seem out to be different from the actual existing assembly and engineering structure. The only solution to address such challenges is to have up-to-date as-built documentation for your engineering plants.

What is as-built drafting?
As-built drafting is one of the most critical processes of any engineering project. The as-built drawings comprise of a final or revised set of drawings created by a contractor. It is submitted after the completion of an engineering project. As-built drawings include all the modifications that have been made in the planning of an original engineering draft.

The reforms can be in the form of major or minor, including details of the shape, design, dimensions, and exact locations of all elements. It contains every change that was made and approved during the construction and commissioning phase, including handwritten notes and paper sketches that comes within the scope of the project. As-built draftings are also known as record drawings.

Importance of Updated As-Built Documentation
Updated as-built documentation contains essential information for engineering projects. Every change made to the drawing must be updated and documented in the as-built drawings, and the older information must be deleted. It would help track the trail of changes with every detail and modified reason. The as-built drawings provide a brief report on variations, date of the change, alteration and its update, and more.

There are various benefits associated with having updated as-built drawings of engineering projects:

• It provides an excellent record of every change made in the multiple stages of the construction project and helps to visualize the next steps. It helps to address the challenges in advance.

• By keeping track of records, you can that the future renovations for the construction gets completed efficiently and on time.

Now that we’ve covered the importance of as-built drafting, let’s dive in deeper to know different types of drafting services:

2D Drafting Services
It is carried out by experts possessing a thorough understanding of product design and manufacturing processes. It includes the creation of precise representation of the objects for engineering and manufacturing projects.2D drafting services defines the structural CAD drafting and detailing for construction projects, which include technical drawings, plan, layout, elevation, and building sections.

3D Drafting Services
3D Drafting services can address some limitations of 2D Drafting services in terms of understanding concepts. 3D CAD modeling and drawings are competent in understanding the design concept. It provides realistic views of your conceptualized building from different angles. It facilitates better visualization and helps clients convey their design concepts requirements through 3D models.

Hence, as-built drafting is a critical function of any engineering plant, and it is always recommended to keep documentation up-to-date to improve efficiency, productivity, and delivery of the project. If you’re looking for as-built drawings services, you can consider outsourcing a multi-discipline engineering services company.
