Physical modeling: Modelers use detailed client drawings, sketches, aerial and oblique photos, and topographic maps to accurately construct scale buildings and surroundings.

  • Model Shops Overview

    RWDI has models shops in three of its locations that keep four boundary layer wind tunnels operating. 

    The skilled modeling staff of each shop are trained in 3D computer applications, physical scale model construction and model instrumentation.

  • Benefits

    Flexibility: Each model shop has similar capabilities giving the flexibility to share the work between shops when necessary.

    Highly experienced and accurate: Our highly experienced model shop delivers accurate models of complex structures such as long span bridges.  Large models ranging from 16’-25’ in height and have taken up to several hundred hours of dedication to complete.

    Client focused: We understand our client’s pressures and do what is necessary to provide them with a quality product that matches their needs.

  • Key Features

    Physical modeling: Our staff of experienced model builders has access to a model shop full of tools to construct scale models and all the details in preparation for testing.  These details range from landscaping (trees, shrubs) to miniature working vehicles (trucks, helicopters).

    Computer modeling: Our staff is experienced in the use of AutoCAD, SolidWorks, Rhinoceros and other modeling software.  Modelers have the experience and creativity to design architectural details at small scales.

    StereoLithography Apparatus (SLA): Once the CAD model is complete and, after the engineering is finished, the computer files become a miniature building.  The SLA machine creates scale models using liquid resin and beams of UV light.  On average, a large building model takes approximately 30 hours to grow.

    ShopBot: If contouring is needed in the test area, the ShopBot is the tool of choice.  A milling tool follows a 3D geometry file created by our staff to produce an accurate terrain model.

    Laser cutter: Some small repetitive details are often needed on our buildings or bridges, so a laser cutter is used to create multiple pieces accurately resulting in quick model assembly.
