What are the Benefits of 3D Laser Scanning Concrete?

3D laser scanning captures a complete digital record of any concrete structure – top to bottom; slabs to columns; before, during, and after construction. 3D laser scanners capture the precise dimensions, contours, and spatial layout of concrete structures by emitting LiDAR laser beams and recording the reflected data. Data is collected from a distance without physically touching the site. The process creates a 3D digital map of the site made up of millions of data points, called a “point cloud”. The point cloud provides 2-4mm accurate existing conditions site data to help contractors and engineers make informed project decisions. Point cloud data can be used for analysis, or 2D drawings and 3D models can be created for planning and evaluation.

These are some of the primary applications for 3D laser scanning concrete:

  • 3D laser scanning can capture the existing conditions of concrete structures, delivering accurate as-built site data for construction and renovation planning.
  • 3D laser scanning is excellent for monitoring cracks, deformation, defects, or changes to buildings and infrastructure over time. By comparing LiDAR scans taken at different times, engineers can identify changes in a concrete structure’s geometry and detect areas of concern.
  • 3D laser scanning can record the location of GPR markings on the concrete surface to permanently document the location of concrete embedments, such as rebar, post tension cables, pipes, ducts, sleeves, and conduits.

By documenting rebar and sleeve positions, contractors can confirm that they are installed correctly and within tolerance before concrete is poured, reducing the risk of structural and MEP installation issues.

3D Laser Scanning Provides Detailed and Precise Data for these Areas of Concrete Construction:

For preconstruction planning, 3D laser scanning can:

  • Capture the existing conditions of a construction site, including topography and existing structures, to help assess the space for concrete work.
  • Verify the accuracy and alignment of formwork before pouring concrete, ensuring it matches design specifications.
  • Document rebar and sleeve positions, confirming that they are installed correctly within tolerance before concrete is poured, reducing the risk of structural and MEP installation issues.
  • Calculate the exact amount of concrete needed, minimizing waste.
  • Check the surface flatness and levelness after concrete is poured to ensure it meets design specifications, reducing the need for rework.

For as-built documentation, 3D laser scanning can:

  • Capture detailed structural dimensions and embedments for completed concrete structures, providing an accurate record of the as-built conditions for future reference, renovations, or repairs.
  • Help to manage the lifecycle of concrete assets by providing accurate data on their condition, useful for planning maintenance activities and budgeting.

For construction monitoring, 3D laser scanning can:

  • Assess the alignment, position, and integrity of pre-cast concrete panels and structural components.
  • Identify and document defects or inconsistencies, such as cracks, shifts, warping, or misalignments, which can be crucial for assessing the structural integrity of concrete elements.
  • Track the progression of movement, settling, and defects in concrete structures to safeguard structural integrity.
  • Document compliance with building codes and regulations by providing precise measurements and detailed visual records.

For design and renovation planning, 3D laser scanning can:

  • Provide accurate data for designing renovations or retrofits by capturing the existing conditions of concrete structures, allowing for better planning and execution of updates.
  • Identify and address discrepancies between the design and actual construction, reducing the risk of costly rework.
  • Import the data from laser scanning into BIM software to create detailed models of the project, to facilitate design planning and avoid clashes with other trades.
  • Document the location of underground utilities, rebar, and post-tension cables located within or under concrete, marked on the surface with GPR, to create 2D drawings and 3D models to improve safety before cutting or drilling into the concrete.
  • Monitor construction progress by comparing scanned data with design models, helping to keep the project on schedule and within budget.

For quality control, 3D laser scanning can:

  • Ensure that concrete structures, such as walls, floors, and beams, meet design specifications by providing accurate measurements and detecting deviations from the intended dimensions.
  • Help verify that the construction conforms to tolerance requirements, identifying areas where adjustments are needed.
    Provide accurate models of concrete structures, making it easier to perform inspections and address potential hazards.
  • Aid in investigating accidents or structural failures by providing a precise record of the concrete structure’s condition before and after the incident.

By leveraging the high precision and detailed data provided by 3D laser scanning, construction professionals can improve the quality, efficiency, and safety of concrete-related projects and operations.
