Annex B, AEI for BUP
First Edition
District has performed a structural evaluation for Fort Lewis barracks (LBC&W) and prepared a
design for structural modification. The Fort Lewis design shall be used for the LBC&W barrack
types in Zones 2B and 3. The BB&A barracks satisfies the requirements in Zones 1 and 2A,
where all barracks of this type are located, and require no structural work.
(c) The demand capacity and level which this seismic upgrade rehabilitation must
achieve is found in the Federal Emergency Management Agency (FEMA) documents FEMA 273,
NEHRP Guidelines for the Seismic Rehabilitation of Buildings and FEMA 274, NEHRP
Commentary on the Guidelines for the Seismic Rehabilitation of Buildings. Any questions
concerning seismic evaluation, rehabilitation design, or seismic criteria can be directed to Ray
Decker in STCX, 503-326-6877. Policy questions shall be directed to Ray Navidi or Charles
Gutberlet, HQUSACE (CEMP-ET), (202) 761-0223.
(2) Roofs.
(a) Roof diaphragms and connections will be investigated, particularly connections to
the frames or shear walls.
(b) If Standing Seam Metal Roof Systems (SSMRS) are used, the structural design of
the roof system and its interaction with the building must be evaluated. It is doubtful that the
SSMRS would imposed structural loading on the building that would be beyond the building's
capacity. However, because the SSMRS adds considerably to the height of the building, a
structural evaluation of lateral load is advisable.
(c) There is a moratorium on the use of cold formed steel load bearing members.
Supports for the roof SSMRS or any other loadbearing structural element may not incorporate
colc formed steel members.
d. Communications.
(1) Background. Old barracks buildings may only have a few administrative telephone
lines and a couple of pay phones. If that is the case, there will not be enough outside cable pairs
or switch capacity to accommodate individual phone lines for each soldier.
(2) BUP must include bringing communications up to current DoD standards. That means
one telephone outlet and one TV outlet per occupancy area. A separate utility closet should be
provided for the communications systems. In most cases, any required exterior upgrade for
telephone or cable TV will be provided by the commercial utility for those services. It may
require extensive upgrade of outside plant telephone infrastructure. All communications issues
must be coordinated with the installation's Director of Information Management (DOIM). POC -
