Army Research Lab Vehicle Technology Directorate

This multi-story structure for the Army Research Laboratory’s Vehicle Technology Directorate consists of 35,363 sf of total space, divided between 19,703 sf and 15,660 sf for the Laboratory and Administrative Wings respectively. The Administrative Wing is two stories with standard office and conference space, and the Laboratory Wing is comprised of high-bay laboratory cells. Both wings meet the governing DoD Antiterrorism/Force Protection (AT/FP) requirements prescribed in UFC 4-010-01, DoD Minimum Antiterrorism Standards for Buildings, including Change 1, dated 22 January 2007. In addition to the typical AT/FP design concerns, the VTD Laboratory Wing will be designed to mitigate potential blast and/or fragment impact hazards presented by the test equipment housed therein.

Hinman’s past performance on this project demonstrates our ability to perform fragmentation analysis, as well as develop new and innovative techniques for blast mitigating design analysis.

Hinman provided minimum structural design and deflagration venting requirements for the members of the critical laboratory cells assuming the worst-case vapor-phase explosion from either jet fuel or gasoline. We also compared the blast response to the fragment impact loading and made recommendations based on the governing response to meet the level of protection.

The Admin wing is designed as Primary Gathering space with an occupancy of more than 50 as defined by the Antiterrorism Force Protection (ATFP) standard UFC 4-010-01 to meet a Low Level of Protection.

The Laboratory space has a low occupancy as defined by the ATFP standard and therefore it is not required to meet these standards. However, the Lab is designed to localize the effects of an accidental explosion and projectiles generated by fuel used within each testing cell. Cell walls, roof, doors, windows and penetrations for each testing cell, as well as the exterior envelope and the dividing wall separating the lab from the admin area is designed to resist an accidental internal explosion and projectiles (Hazard Divisions 1.1 & 1.3) generated by the maximum amount of JP8 fuel used in a single cell. This design meets the requirements of NFPA 30-Flammable and Combustible Liquids, UFC 3-340-02 and ASCE - Design of Blast Resistant Buildings in Petrochemical Facilities. Because the projectile impact exceeds the Very Low Level of protection based on force protection requirements, all structural walls are designed to meet 100% containment without back face spall for all structural elements as defined by the DDESB.
