Recent Projects—Concept Development
Naval Facilities Engineering Command, Atlantic Division
Under contract to the design firm, Glenn & Sadler, Lewis & Zimmerman Associates facilitated a Function Analysis Concept Development (FACD) workshop on a new F/A-18 double module, Type 1 Maintenance Hangar at Naval Air Station (NAS) Oceana, Virginia.
This Base Realignment and Closure (BRAC) project provided for the relocation of F/A-18 wings to NAS Oceana from NAS Cecil Field, Jacksonville, Florida.
The FACD is a cooperative effort by the consultant architect-engineer (A-E) design team, the user/customer representatives, and the Navy. A FACD is typically the on-site development of a conceptual design in response to functional, aesthetic, environmental, base planning, site, budgetary, life cycle and other requirements.
As a result of the FACD, the hangar was redesigned to place the shops and administrative (O1/O2) spaces between the two hanger modules. This arrangement permitted direct access to the flight line from the O1/O2 spaces, and provided storage space without adversely affecting hangar area. Furthermore, this design negated the need for a cantilever structure and reduced the fire protection system requirements, leading to significant cost savings.
The FACD afforded participants a better understanding of the project's needs and constraints, enabling the Navy to obtain additional funding to complete the project with the full square footage specified in the DD Form 1391.
This effort was awarded the 2000 Department of Defense Award for Outstanding Achievement through Value Engineering.
U.S. Route 29 Interchanges—Maryland State Highway Administration (SHA)
Route 29 is a major north-south route between Washington, D.C. and Baltimore, Maryland. SHA is converting five signalized intersections and two non-signalized intersections on U.S. 29 to grade-separated interchanges. Several of the proposed interchanges are located in highly developed areas with structures in all quadrants. The goal of the study was to optimize operations while minimizing the impacts to right-of-way.
The study was conducted at the conceptual stage with members of the VE team drawn from SHA staff and representatives from the engineering firms responsible for the designs of the interchange projects.
The study generated major reductions in right-of-way requirements and the definition of a less invasive series of projects. In one instance, in lieu of having the minor crossroad bridge over U.S. 29, U.S. 29 was lowered to proceed under the crossroad, thus saving a shopping center in the northeast quadrant. In another instance, an overpass was converted to an underpass and realigned to solve a safety issue caused by a steep downgrade leading to a "T" intersection. This also eliminated severe impact to the road adjacent to U.S. 29. Funds saved on some of the interchanges were transferred to other interchanges to achieve overall project goals.
