1. Chemical Plant 3D/High-Definition Scanning and Modeling

    A specialty chemical company had three centrifuges in a 200,000-SF warehouse facility that needed to be replaced or rehabilitated. The client requested a 3D scan to better identify the location of all the centrifuges, since no as-built plans existed. The replacement/rehabilitation was going to be complex because of the amount of piping and electrical work,…

  2. SR 2047 Flaugherty Creek Bridge Rehabilitation

    The SR 2047 (U.S. 219 Business) Bridge over Flaugherty Creek is a stone masonry arch bridge listed on Pennsylvania’s Historic Bridge Inventory, and was deemed structurally deficient after 100 years of wear and tear from exposure to the elements and heavy traffic volume. The bridge is one of the few stone masonry arch bridges in…

  3. Pequea Boundary Survey

    When the Lancaster County Conservancy bought 143 acres to convert to public-use parks, the purchase required a complete retracement survey to ensure the correct property was transferred. Normally, a recent survey could be used as a base, but this property hadn’t been mapped since the 1930s. The long time between surveys meant many original corners…

  4. Commercial Redevelopment Boundary Survey and 3D Modeling

    A development client looking to repurpose an existing restaurant location needed the site’s building plans before they made a final decision on whether to proceed. As complete records did not exist, our client hired RETTEW to perform a variety of surveys and recreate the plan set. We performed 2D and 3D surveys to ensure a…

  5. 520 Hamilton 3D Laser Scanning

    Part of the larger City Center Allentown project is 520 Hamilton, a new six-story mixed-use building with retail and luxury residences. Ensuring the preservation and integrity of the buildings surrounding the site during demolition and construction required precise measurements. To accomplish this, RETTEW used 3D laser scanning in addition to traditional surveying methods. This technology…

  6. Knouse Foods Boundary and Hydrographic Surveys

    Knouse Foods, a long-standing RETTEW client, requested boundary surveys with specific title commitment requirements for their six processing plant sites. This assignment required extensive boundary surveys of hundreds of acres of land within a relatively short timeframe. RETTEW completed the boundary surveys on schedule and continues to provide various surveys on these sites as required….

  7. Compressor Station 3D Scanning

    Turn-Key Specialists, Inc. (TSI), needed to obtain scans and 3D models for three separate compressor stations in Susquehanna County to help their client plan for additions to existing compressor stations and other potential construction activities. Because of our strong working relationship with TSI and the detail and quality of a previous high-definition scanning project we…

  8. Pipeline Boundary Survey for 300 Line

    A natural gas client planned to upgrade its natural gas pipeline transporting raw material to the Northeast. The client’s goal was to enlarge the pipe size because of the increased demand in the region. Rugged terrain, incomplete records, and landowners not in agreement with the action were complicating the process. RETTEW’s survey group quickly mobilized…

  9. Storage Tank Precision Monitoring 

    A natural gas client was building two 5-million-gallon steel tanks to store freshwater for its hydraulic fracking process. They also needed to monitor tanks for movement during a hydrostatic test of the structures. The project’s major challenge was scheduling; a survey crew needed to be on call around the clock for the duration of emptying…

  10. Iroquois National Wildlife Refuge GPS Control Survey and LiDAR Mapping

    The U.S. Fish and Wildlife Service (USFWS) requested updated topographic mapping of 11,000 acres for future land planning and management. The widely varied terrain and density of vegetation across this large project area required the use of aerial LiDAR because it is the best solution to achieve the appropriate level of detail and accuracy. The…
