If you are a construction professional, architect or engineer, you have probably heard of as-built drawings. These drawings are important to ensure that your construction project is on the right track and to avoid costly mistakes. In this article, we will discuss how to create as-built drawings and give you some tips to make the process easier.
Creating as-built drawings can be a tricky process, especially if you are not experienced in the field. Many construction projects develop problems and delays because of as-built drawings, or the lack thereof. Having to redo work on site can lead to a longer build time, a higher budget, and unhappy clients.
How to Create as Built Drawings
The goal of as-built drawings is to create an accurate representation of all the elements and systems that were installed in the building or structure. These drawings can be used to compare what was designed to what was actually built. Below are some steps on how to create as-built drawings:
1. Gather Information
To get started with as-built drawings, you need to gather as much information as possible about the construction project. This includes any design plans, blueprints, construction schedules, and specifications. You also need to have access to the site and take accurate measurements of the structure itself and any systems installed, including plumbing and electrical systems.
2. Draw the Plan
Once you have all the necessary information, you can begin to draw the as-built plans. You can use CAD software such as AutoCAD or Revit, or sketch it out by hand. Make sure to include all the systems and elements in the drawings and label them appropriately. It’s essential to be accurate as incorrect information can cause problems on the site and create delays that may be costly.
3. Coordinate with Contractors
As-built drawings aren’t exclusively the architect’s responsibility, nor are they solely the construction manager’s responsibility. Coordination between all parties involved in the project is crucial to ensure that everyone is on the same page when it comes to the as-built plans.
4. Keep the Record Updated
The record must remain updated throughout the construction project. If any changes are made, update the plan to reflect these updates immediately. This way, as-built drawings can stay up-to-date.
Benefits of Creating as Built Drawings
Creating as-built drawings has several benefits. It can speed up the design process for future projects, whether for renovations, additions or landscaping. It also helps resolve issues during construction, reducing errors and preventing rework, ultimately saving time and money.
Experience
As architects, we know the importance of as-built drawings. On a recent project, we worked on a rehab project for an 80-year-old church. The client requested affordable updates to the building and subsequent drawings. First, we identified the church’s various systems and used that data to create the as-built plans. We then used the accurate plans to make modifications and updates to the building. Finally, we updated the drawings for the client, providing them with new as-built plans to reflect the changes we made. Equally important, each contractor could refer to the plans for updates and changes.
Some Examples of the Importance of as-built drawings
Some general examples of where as-built drawings would have been helpful include, but are not limited to: - Working within existing site conditions - Updating existing data or drawings - Designing a new addition to an existing structure - Making interior renovations
Question and Answer
Q: How is technology transforming the as-built drawings process?
A: Technology has revolutionized as-built drawings over the past few years. With computer-aided design (CAD) software, designers can now create precise digital plans, which allow for more accurate measurements to be taken. 3D scanning and drones have made it possible to create incredibly accurate as-built drawings in a short amount of time.
Q: Who is responsible for creating as-built drawings?
A: As-built drawings are typically the responsibility of the architect or designer responsible for the original plans. They can also be created by a specialist specifically hired to create them. It is important to note that all contractors have a hand in making these drawings possible, so coordination is necessary to ensure all information is communicated effectively.
Q: How do as-built drawings differ from record drawings?
A: Record drawings show how the structure was built, whereas as-built drawings show the installation of different systems into the building structure. Record drawings are made after a building is constructed; as-built drawings show the building’s progress during the building process.
Q: What is the importance of coordinating with contractors when creating as-built drawings?
A: Contractors will provide valuable insights into design and construction issues that might arise during construction. Having comprehensive and accurate as-built drawings can help prevent time delays, various communication issues, and misunderstandings, leading to a more successful build and happier clients following completion.
Conclusion of How to Create as Built Drawings
Creating accurate as-built drawings is essential to a successful construction project. This article has provided some tips on how to create as-built drawings and why they are important for future projects. By gathering information, drawing the plan, coordinating with contractors, and updating the plan regularly, you can ensure that your as-built drawings are precise and thorough. Be sure to consider hiring a specialist to help with specific aspects of the drawing process to make the construction go as smoothly as possible.
