VALUE ADDED SERVICES

ATFP Modeling & Design: A two step-process was utilized to deliver the ATFP Window Framing Betterment. There were 34 different window types and a total of 364 windows affected by this requirement. The first step utilized High-Fidelity, Physics-Based (HFPB) finite element simulations using the commercially available LSDYNA software. The second step utilized a bundle of protective software sponsored by the United States Army Corps of Engineers including CONWEP, SBEDS, and HAZL.

DID YOU KNOW?

While designing a glazing system to meet the AT/FP criteria is straight-forward, anchoring such windows is very challenging due to the existing un-reinforced façade elements and the offset of the window from the interior stud wall system.

The bridging documents proposed six-inch deep structural steel tubes to support the windows. Assuming a 10 ft. long element, the lightest tube would weigh around 65 lb. Our approach was to use more efficient systems to resolve the blast loads imposed by the window systems. Hence, cold-formed, six-inch deep, 16-gauge metal studs were selected, each weighing approximately 20 lbs.

Rising Value

Betterments included:

• Occupied one month earlier than contractually required.

• Alternative electrical distribution design.

• ATFP window framing – cold formed six-inch deep, 16-gauge metal studs, saving 70% in material weight alone.

• Interior stainless steel railings. Pickets and posts were to be painted steel.

• Cus tom VCT, three color patterns.

• Accent wall paint.

• Cus tom ceramic tile at cadet bathrooms.

• Door hardware upgrades.

• Full-scale barrack/dormitory mock-up including FF & E.

$1,000,000

The total value of betterments added by the Design-Build Team.

The Design-Build Team initiated a new location for the padmount service transformer and the main electrical room from the basement level of Division 54 to the basement of Division 51 saving $ 250,000 which USMA then used to add new card readers to the scope of work, illustrating continuous design-build value engineering.
