• A Better Way to Use Point Clouds in AEC Projects

    Laser scanning helps lower building contractor risks by ensuring as-built drawings are accurate and by exposing any inaccuracies early in the process, before they turn into change orders during construction. One area where contractors increasingly want to use point clouds is in the QC/QA process. Scanning the real-world construction site and comparing the point cloud data with the …   Read More

  • Three Projects That Show How GCs Apply BIM

    Practically all general contractors have heard about building information modeling (BIM), but what are the applications of this breakthrough technology in real life? In 2015, we checked in with Russell Gibbs and Shawn Mancill at Brasfield & Gorrie, one of the nation’s largest privately held construction firms, to learn more about how they are tying …   Read More

  • When to Use a Scanning Total Station vs. a Dedicated Laser Scanner

    When is it best to use a scanning total station versus a dedicated laser scanner? It’s a question we’re often asked by professionals who want to improve accuracy and reduce rework on their construction projects. In both new construction and renovations, the rich, complete data captured with a laser scanner provides the required information with …   Read More

  • Four Steps to Connect Models to Field Work

    For most contractors, accurately connecting information from the office to the field, and from the field back to the model in the office, is an ongoing challenge. In the office, the building information modeling (BIM) or virtual design and construction (VDC) group can push information and models out to the field all day long, but …   Read More

  • Laser Scanning: A Better Way to Analyze Concrete Slab Flatness

    Most of the methods used today for conducting slab flatness analysis are manual and labor intensive. Floor flatness/floor levelness (FF/FL), a commonly used method, requires the creation of a grid on the concrete slab following a set of specifications before taking manual readings. Contractors that use the ASTM E1155 standard method for determining floor flatness (FF) and …   Read More

  • Video: Laser Scanning for Construction

    In the planning stage, a laser scanner is a powerful tool for analyzing a construction site. High detail and unique visualization options help designers get a more complete picture of the site. During construction, scanning can be used to check progress or verify standard compliance. It can also be used to obtain valuable information in …   Read More

  • UAS Enable Faster, Safer Curtain Wall Inspections

    Inspecting the curtain wall on a multistory building is not a job for the faint of heart. Workers spend hours in lifts or on high-rise swing stages, taking photos and measurements to document potential problems. The work is expensive, time consuming and dangerous. The progressive leaders of Brasfield & Gorrie, one of the largest privately …   Read More

  • BIM Field Trip Keeps Four-Story Residential Construction Project on Track

    Ensuring the perfect fit of steel beams in commercial and residential buildings requires more than line drawings and spot measurements. On complex structures with contemporary designs, creating a seamless flow of accurate data in a 3D digital environment is often the only way to get the job done right the first time around.   Read More
