Geomatics

Stewart’s Geomatics group continues to evolve with developing technology, today providing geographic data acquisition in a variety of ways that go well beyond traditional land surveying. Our primary services include Surveying, Subsurface Utility Engineering (SUE), High Definition Surveys, and Unmanned Aerial Systems (UAS), which allow us to collect data in safer and more efficient ways than ever before.

Survey

Led by experienced professional land surveyors, Stewart provides surveying services on projects of all types and scales, from greenways and roadways to new buildings on dense university campuses and large parcels of land for private developments. Stewart currently provides surveying in North Carolina, South Carolina, Tennessee, Virginia, and West Virginia.

Services provided:

  • Topographic
  • Photogrammetric Control
  • Geodetic – GPS
  • Environmental
  • Subdivision/Recombination Platting
  • ALTA/NSPS
  • Route
  • Existing Condition
  • Boundary
  • HDS & SUE Support
  • As-Built
  • GIS
  • Bathymetric/Hydrographic
  • Construction
  • Subsurface Utility Engineering

    Stewart provides SUE services as a standalone offering or packaged with our other design disciplines, providing our clients with fewer consultants to manage. With a SUE team involved throughout the entire design phase, we find potential challenges are identified early and swiftly.

    Stewart’s SUE staff has experience in a wide array of market sectors including utility, municipal, education (K-12 and university), commercial, health care and DOT, as well as considerable experience with military projects. We know how to navigate different market obstacles and meet all project needs.

    Our SUE team can provide the following services:

    • SUE Quality Level A-Level D
    • Ground Penetrating Radar
    • Void Detection
    • Utility Locating
    • UST Mapping
    • Cemetery Mapping
  • GIS Utility Mapping
  • Concrete & Rebar Scanning
  • Non Conductive Pipe Locating
  • Pipe Video, Condition & Assessment
  • Vacuum Excavation Test Holes & Trenches
  • High Definition Surveys

    Stewart uses the latest in high-speed 3D laser scanning technology to ascertain detailed measurements while documenting existing conditions. Our technicians can produce incredibly detailed images of complex environments and geometries in just minutes.

    This technology is ideal for 3D building documentation, construction supervision, reverse engineering, building sites, roads, landscape features, historic preservation of facades and complex finishes. High definition surveying is also well-suited for documentation of interiors and technical installations such as building services, conveyor systems or process installations. Stewart can measure products and components of every building structure or infrastructure to produce precise data and 3D surface models – no matter its shape or size.

    Stewart is well-versed in delivering this high-quality and large magnitude of data in an efficient and useable manner. To this end, deliverable methodologies include model generation in REVIT, AutoCAD, Kubit and other point cloud generation software.

    Additionally, Stewart has the capability of developing accurate “as-built” REVIT models of existing buildings by modeling within the scanned point cloud. This can be done in significantly less time and with much greater accuracy than the typical process of building the model using record drawings and field verification. This can be extremely valuable in initiating complex renovation and additions projects.

    The following scanning services are provided:

    • 3D Laser Scanning
    • HDR Photography
    • BIM Modeling
    • Clash Detection
    • Visualization
  • Videography
  • Reverse Engineering
  • Heritage Documentation
  • As-Built Condition Assessments
