As-Built Drawings in Construction

No construction project goes exactly according to plan, and it is difficult for contractors to keep a record of all design changes and reworks that were made during the building process. When completing a renovation or building modification, it is important to have an as-built: the exact dimensions and locations of all building elements.

As-built drawings are often out-of-date and inaccurate, leading to unexpected issues and project delays. An accurate record of existing conditions can expedite project planning and decision making. Renovations or modifications can proceed smoothly when teams have precise architectural, structural, and MEP system specifications. Accurate as-builts reduce the delays and costs from mistakes and reworks made from working with outdated plans.

What are As-Built Drawings?

As-builts are the set of drawings or plans that represent the current state of a building or site. Buildings can go through many modifications during the construction process. For example, the location of a wall, window, or system component can be moved or relocated. As-builts provide an accurate record of the current building information, including the layout, dimensions, and material specifications of architectural, structural, and MEP features, walls, windows, doors, stairs, roof, railings, exposed columns, beams, equipment, piping, and ducts, etc.

As-builts can be recorded throughout the life cycle of a project. They can be generated during construction to document design changes from the original plans. And, they can be produced by general contractors and/or subcontractors at the end of a job, during closeout. These are often referred to as final as-builts or for-record as-builts.

How Do You Capture an As-Built?

3D laser scanning is the best method to capture precise measurements and aboveground details of a project site. 3D laser scanning uses LiDAR technology to quickly record the existing conditions of a building, site, or facility in the form of a point cloud. The precise details of the exterior and interior of buildings, foundations, structure, piping, and equipment are captured with millimeter accuracy, delivering exact building dimensions, locations, and layouts.

Point cloud data can be opened in CAD software, such as Revit and AutoCAD, to generate highly detailed 2D CAD drawings, 3D BIM models, 3D meshes, TruViews, virtual tours, and utility locate maps.

How Can Accurate As-Builts Save Time and Money?

According to a report from Autodesk and FMI, poor project data and miscommunication account for 48% of all rework on U.S. construction sites. They state that professionals spend four hours a week dealing with rework-related activities, such as managing the mistakes on a project that result in rework, assessing the associated costs, and determining why the mistakes happened.

Furthermore, this lack of information and bad data results in poor decision-making. In another study from Autodesk and FMI, decisions made using “bad data” are estimated to have cost the global industry $88.69 billion in rework alone, accounting for 14% of all rework performed in 2020.

Complete and accurate as-built data ensures project teams have precise building layouts to improve communication, ensure reliable project planning, determine project costs, reduce change orders, assign tasks to the construction team, and record construction progress. GPRS 3D Laser Scanning services deliver updated as-builts for peace of mind before beginning any construction project.

These are some of the benefits of as-built plans:

  • Obtain Building Layout – Having a precise building layout is crucial in design planning, construction management, and facility maintenance. Accurate floor plans and 3D models with 2-4mm accuracy help project teams expedite design planning and save time by knowing the locations of the building components and systems on the site.
  • Improve Communication – Communication is improved, teams can discuss plans while each has access to the same information, creating a more dynamic working environment. As-builts decrease calls, emails, and messages with a single source of truth.
  • Expedite Project Planning – As-builts are dimensionally accurate, measurable, and shareable data sets for reliable project planning.
  • Estimate Project Costs – Information on project layout and building materials allows teams to specify design changes and estimate costs.
  • Reduce Change Orders – Accurate design plans are produced from the start, expediting fieldwork and reducing change orders and delays.
  • Assign Tasks to Construction Team – Project Managers provide the team with the proposed design and assign tasks to the construction team, reducing project downtime.
  • Record Construction Progress – As-built drawings allow contractors to track the progress of the project and see what work needs to be completed, allowing them to set realistic completion dates.

Who Uses As-Built Drawings in Construction?

Construction projects are complex and dynamic. Accurate as-builts help to plan and manage unforeseen site conditions that may arise during the construction process.

These are some of the project stakeholders who utilize construction as-builts:

  • Contractors – The contractor is usually overseeing the actual building construction, as-built drawings and models are a crucial source of information, as they communicate the existing building conditions and take all guesswork out of the equation.
  • Design Teams – Use as-builts as a clear starting point for construction planning, with access to accurate data, they can detail the additions, deletions, and other changes made to a project during the design process.
  • Engineers – Use precise as-built data such as dimensional comparisons, floor surface contours, bolt hole locations, and precise prefabrication measurements are necessary for solving complex engineering challenges.
  • Facility Maintenance Teams – Utilize as-builts to understand the layout and components of infrastructure, systems, and utilities, making it easier to perform repairs, updates, or routine maintenance tasks.
  • Architects – Use as-builts in the form of 3D BIM models to complete design plans with accurate data and share access to all project stakeholders.
  • Real Estate Professionals – Use as-built drawings to assess the property's condition and layout and ensure its compliance with codes and regulations.
  • Environmental Consultants – Use as-built drawings, maps, and models to identify underground utilities and potential environmental hazards on a property and get the crews home safely.
