Metal helps meet security goals for maintenance facility

pacoima1Located on 17 acres (7 hectares), the 7,800-square-foot (725-m2), $1.2 million project at the Pacoima Maintenance Facility in Pacoima, Calif., features a new 300-square-foot (28-m2) guard station, restroom, automatic entrance and exit gates, entry security fencing enclosure and project signage.

The existing facility has been in operation for more than 60 years and contains electrical, mechanical, carpentry, and vehicle maintenance shops and warehouses for the Los Angeles County Fire Department System. Also contained on-site are vehicle storage garages for large trucks, heavy earth moving equipment and Urban Search & Rescue vehicles. Care was taken with the project to use low-maintenance materials compatible with the industrial character of the existing metal and concrete masonry buildings on the site.

AEP Span, Fontana, Calif., supplied 1,500 square feet (139 m2) of its 18-gauge Nu-Wave Corrugated Siding with a Zincalume steel/Zincalume Plus finish on both sides in AEP Colonial Red; 400 square feet (37 m2) of its 22-gauge, 16-inch- (406-mm-) wide Span-Seam metal roof panels in AEP Colonial Red; 400 square feet of its 20-gauge, 16-inch-wide Prestige Series Soffit Panels in AEP
The 17,000-square-foot (1,579-m2) City of Bothell Public Works Operations Center Administration Building in Bothell, Wash., was designed as a functional, low-maintenance, two-story administration building that is a pleasure to work in and a source of pride for the city and its employees. The facility includes staff locker rooms, a public meeting/lunch room and flexible open office spaces.

The architepacoima2ct, Hutchison & Maul Architecture, Seattle, desired a low-maintenance wall cladding material that had a textured appearance. AEP Span, Fontana, Calif., supplied metal wall panels in a mini V profile and Span-Lok standing-seam metal panels in White for the roof. Architectural Metal Works, Wilsonville, Ore., was the metal siding and roofing contractor.

Anticipated to achieve LEED Silver certification, sunshades have been installed at the south and east windows, roof skylights and large north-facing windows provide natural light and views, while a deep cantilevered roof overhang at the west end mitigates sun exposure and shelters an outdoor area adjacent to the lunch room.

Colonial Red. Tampa, Fla.-based McNICHOLS Co. supplied 600 square feet (56 m2) of its 1/4-inch-
(6-mm-) thick Perforated Steel Plate with 1-inch (25-mm) diameter holes with staggered centers in an Electrozinc plated finish.

Goals for the project included providing 24-hour security for the maintenance yard; providing
visibility of the entrance from distant street approach; providing visibility of all vehicles, occupants and pedestrians from within the guardhouse and inside the facility; providing street presence and identity for the facility and providing a visible location for facility signage and the street address.

Perforated metal was used for gate panels, and corrugated metal was used for fence panels. Red corrugated fence panels help "grab" the eye and provide distant visibility of the entrance from either direction, while perforated metal panels allow visibility through the gates from either direction. An upward titled metal roof allows open visibility from the guardhouse toward the street. The coordinated use of metal panel colors provides a unified presence at the street, while the red corrugated metal panels provide a striking backdrop for the facility signage.

Metal was selected for its compatibility with existing older and newer metal shop and warehouse buildings on site which used similar materials in a more traditional way, along with its versatility in new applications for the entrance project, and its long-term durability. Also, project elements were color coordinated by using the same finish on all metal fence, roof and soffit panel surfaces.

William Loyd Jones Architect, Venice, Calif., was the architect; Segovia Construction, Long Beach, Calif., was the general contractor; Crown Sheet Metal, Los Angeles, was the sheet metal installer; and M.A.S. Iron, Los Angeles, was the perforated metal installer.
