  • Develop and document test plans and/or test plan inputs required by the customer to execute program testing.
  • Structural design of test-setup configuration, develop and/or review and approve shop drawings, and inspect and/or supervise construction related activities at the test site.
  • Work with materials sub-contractors to ensure test apparatus structural elements are properly constructed, on-time, and well-coordinated with the test site team.
  • Post-process test data and coordinate with the instrumentation engineer to finalize data capture, photo, and video formatting, and the required customer deliverables.
  • Documentation of pre- and post-testing conditions and develop test reports.

Protective Design Consulting Work

Because our testing programs have seasonal highs and lows, the position will also support Stone’s overall protective design consulting work. This may include blast vulnerability assessments, blast resistant building design and detailing, building assessment site visits, etc. This will be accomplished under the guidance of, and collaboration with, the overall Stone technical team.

Extreme-WoodLam (EWL) Panels used to Blast Strengthen a Conventional Pre-Engineered Metal Building (PEMB)

Stone Security Engineering, PC,(Stone)  in collaboration with Stone Protective Solutions, LLC  (SPS, LLC) and Stone Protective Solutions, Ltd (SPS, Ltd) worked with Advantage Midstream to strengthen a conventional pre-engineered metal building design in western Texas for blast resistance using minor design modifications and the installation of our Patent Pending Extreme-WoodLam (EWL) panels on the building exterior. Figure 1 and Figure 2 show 3D renderings of how the EWL panels can be incorporated with the building cladding. Figures 3 shows actual construction photos and final building installation will be published soon.

Figure 2.  EWL Panel Connections to Girts/Purlins Concept

Figure 3.  EWL Panel Installation During the PEMB Construction

The Patent Pending EWL panels were developed by Stone and SPS, LLC and fabricated at the Stone Protective Solutions, Ltd. plant and shipped to the construction site, along with installation instructions, labels and design certificate letter for the blast load rating.

The EWL panels proved easy, fast and cost-effective to integrate into the building cladding profile. The EWL panel system steel cladding panels are efficiently and quickly installed directly over surface of wall girts and roof purlins and doesn’t require the use of steel self-tapping bolts.  

The panels were fabricated to unique sizes to fit snuggly on the PEMB and the workability of the panels made connecting them to the building framing a breeze. In addition, the EWL panels improved the thermal insulation of the building exterior.

 Overall, the EWL panels provide a blast resistant product with the workability and enhanced insulation properties of wood panels. Both properties make EWL panels an attractive blast resistant solution for building modifications/retrofits and for buildings located in hot and cold weather environments.
