What Are “As-Built Drawings” And Why Are They Important in Construction?

What Are “As-Built Drawings” And Why Are They Important in Construction?

There are various representations of facility documentation that can be specified during the facility life cycle. Design drawings depict the facility through the design process and thus reflect what it will become. They aid in the formation of consensus and the formulation of architectural and engineering decisions.

Bid documents identify the facility to the point that a precise price can be calculated. The outcomes of the architect’s and engineers’ decisions, as well as their instructions to the contractor in the form of drawings and specifications, are illustrated in construction documents.

Contractors or project managers create “as-built drawings,” which depict the facility as it was built and as it is supposed to be at the time of commissioning. Finally, Demolition drawings are used to illustrate the scope of work involved in deconstructing a building or sections of a building. All of these records can be categorized as facility documentation when taken together.

What are as-built drawings?

There may be some differences between the finished building and the drawings since both concept design drawings and shop drawings may go through several revisions. This is where as-built drawings come into play. As-built drawings are also known as record drawings, red-line drawings, and as-built plans.

As-built drawings are representations of the facility’s current conditions. They depict the structure as it stands today, not as it was intended. Since buildings don’t always go according to plan, it’s a good idea to schedule as-built drawings even though you already have a collection of drawings. Nothing compares to a series of sketches that have been measured and field-checked.

As-built drawing is a revised drawing that a contractor creates and submits after a construction project is completed. They include any revisions to the original sketches made during the design process, as well as an exact rendering of the building and property as it would look after completion. All items within the scope of the project should have their form, measurements, and specific positions detailed in as-built renderings.

Any changes, whether minor or major, should be recorded, as well as a record of approvals for the changes. Also, minor information such as materials used should be registered if they vary from those specified in the original design, with planned but unused materials simply crossed out for future reference.

Characteristics of As-Built Drawings

  • As-built drawings are produced either before or after the design phase has been completed. It provides an indication of the actual project that was completed.
  • To ensure that everybody looking at the plan understands the building activity, abbreviations are not used in as-built drawings.
  • All variations in design, venue, materials, and so on are clarified in writing with the date, along with all changes from the original drawings. As-built sketches can be aided by photos and maps depicting the before and after of an activity, which can help to prevent potential misunderstandings.
  • The adjustments made during the building process are noted in red ink on the original drawing, which can then be used to prepare as-built drawings.
  • The adjustments made during the building process are noted in red ink on the original drawing, which can then be used to prepare as-built drawings.
  • Fix the colour code, drawing size, and formats before preparing as-built drawings to ensure that the drawings are correct. For example, red represents deleted items, green represents added items, and blue represents special instructions and information. As-built drawings can be muddy due to inconsistency in identifying changes and alterations.
  • The scale of the as-built drawing is close to that of the original drawing, allowing for easy comparison and comprehension.

Where Are As-Built Drawings Used?

Accurate and Detailed plans are critical for the success of any construction project. If the contractor encounters challenges with materials, the location, or governmental entities over the course of a project, the building’s features are likely to change. In particular, for commercial construction projects, as-built drawings are needed to document these changes and preserve an accurate image of the building as it currently exists. Here are some different applications of As-built drawings in Construction

As-Builts for Success Before Construction Begins

Applications of As-built Drawings In Construction

1. New Construction

Contractors will face various obstacles when constructing a new building that existed only on paper and will need to change their building plans in response. These as-built sketches document the changes as they occur during construction so that an accurate drawing of the building is available when it is finished.

2. Renovation/Remodelling

It is important to have a thorough understanding of the current state of the building before embarking on a renovation project. As a result, for a safe and effective renovation, working with current drawings is critical.

3. Maintenance

Small updates and modifications will be made over the life of a building. The construction staff of a building is responsible for updating as-built drawings to represent any improvements to the structure, ensuring that a correct drawing of the structure is available at all times.

Why are As-Built Drawings Important?

For various purposes, as-built sketches may be beneficial to all parties involved in a construction project.

Having a full and accurate collection of as-built drawings is critical for clients and building owners. Since as-built drawings contain records of all installations, they are extremely useful if the owner wishes to change the building in the future or wants to troubleshoot issues.

Contractors benefit from as-built drawings because they have a detailed record of improvements made during the construction process and make it easier to visualize the next steps. This makes it much easier to spot complications caused by the changes and solve them before they become a problem.

As-built drawings are also an important part of the final sale since they are important to potential buyers of the land. They serve as a basis for any potential creation or changes and provide a simple testament to what is being sold and purchased.

In general, as-built drawings are an essential component of any effective construction project. During design, modifications to the original building plans are unavoidable, but diligent use of as-built can result in happy stakeholders and a project that is expertly constructed.
