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.

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.

Stone is Seeking a Blast/Structural Design and Testing Engineer

Stone is an internationally recognized consulting firm specializing in the protection of people, buildings, and structures from accidental and manmade hazards. We focus on Extreme Loading (including blast, ballistics, vehicle ramming, and forced entry resistance) and safety, engineering and design. Stone has offices in New York and the Washington DC Metro area and supports testing at the Stone-OBL Large-Scale Blast Test Facility in Bend Oregon.

This position is based in Salem Oregon and will support Stone’s operations related to:
• Research, product development and testing for extreme loads (blast, ballistics, and forced entry), and
• Blast/Protective design consulting work for our east coast offices.

Research, Product Development and Testing

The position will provide support for product development, test planning, test setup design, and test execution support for extreme loading test efforts for a variety of Protective Design Products and/or techniques applicable to the Protective Design Industry. Roles include the following:

• Provide structural engineering analysis and detailing support for development of Protective Design Products for customers. This will be accomplished under the guidance of, and collaboration with, the overall Stone technical team.
• Regular interaction with Stone’s in-house testing technical team and the customer program team to define test objectives and execution requirements to support program implementation.
• Coordinate with the test team, customer test lead, and test site manager on execution processes, procedures, quality control and documentation requirements.
• Attend meetings and provide guidance on test objectives and requirements during the test planning process.
• Develop and document test plans and/or test plan inputs required by the customer to execute program testing.
• Structural design of test-setup configurations, 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.

Required Qualifications:

• Bachelor of Science, or higher degree, in civil, structural or mechanical engineering and 5+ years’ experience.
• Practical experience and knowledge of structural design and construction, including concrete, steel, wood, glazing and other building materials.
• Works well within a team but does not require constant supervision.
• Able to communicate easily and efficiently with both technical and non-technical staff, clients and contractors.

• Ability to travel to Bend Oregon on a regular basis.
• Ability to obtain and maintain a Department of Defense Secret clearance as needed, which includes U.S. citizenship.

Desired Qualifications:

• Experience with test procedure development and test execution.
• Experience with on-site building construction.
• Experience with dynamic and/or blast resistant analysis and design.
• Licensed Engineer in the State of Oregon or able to obtain licensure.
• Knowledge in test methodology, project management, and requirements verification/validation.
• Experience in documenting test performances, failures and corrective actions.
• Experience in and supporting test program for design reviews, schedule meeting, liaison with test ranges. Etc.
