Los Alamos County Airport
This project is located at the Los Alamos County Airport which is partially built upon the old Los Alamos (LA) landfill used in the 1940's. The steep rim of Pueblo Canyon serves as the base of the landfill. When the debris from the original landfill began to migrate into the canyon, LA County brought in North Wind, a remediation contractor from Idaho to stabilize the site and update the Airport's hangar facilities. North Wind subcontracted JB Henderson to build a concrete retaining wall at the canyon rim to prevent further migration of debris. The wall is located approximately 100' below the canyon rim and the airport facilities.
At this elevation it is not possible to drive a concrete truck to the level of the wall structure. Instead, the crew used two concrete pump trucks to reach over the rim to place concrete into the forms. A steep temporary road was built for material delivery and access. Only all-terrain fork trucks or four wheel drive vehicles were able to travel the steep road. Overall the project was extremely challenging and provided a chance for the crew to think outside the box and utilize unconventional methods. The completed project was a success.
The Radio Shop Replacement Project
The Radio Shop Replacement Project is a design-build project of a 7,000 square foot service and support facility for Los Alamos National Laboratories. JBH was a subcontractor to B&D Industries, Inc. Our subcontract included all work other than design, electrical and controls. The facility consists of a high-bay service area that can accommodate vehicles as large as a fire truck for radio installation and maintenance, office area for technical support personnel, and a radio equipment room linked to a 70-foot high tower. The building sits on a concrete slab with turned-down footings to support the structure. Exterior finish is exposed CMU or stucco. Aluminum windows and skylights provide natural lighting. The interior finishes are drywall, carpet or VCT and acoustical ceiling tiles. The restrooms have ceramic tile floors and wainscot. Two large coiling doors provide drive-through access for trucks requiring service.
The MESA Tooling Subproject
The MESA Tooling Subproject provided a complete functional and operational semi-conductor toolset for the MicroFab cleanroom facility at Sandia National Laboratories, and a limited toolset for the MicroLab facility. JBH's scope of the tooling project for the MicroFab included tools that had to be installed or relocated. These facilities contained specialized functions such as clean rooms, metallurgical process, thin films, microcircuit production, and electronic fabrication. Several specialty gasses were involved with the tool installation. JBH was required to furnish, as necessary all supervision, labor, materials, consumables, tools, equipment and vehicles to perform structural, mechanical, electrical, high purity and cleanroom modifications. This included equipment installation and/or relocation for all machining, manufacturing, production facilities and associated incidental utilities in special access areas. Work was performed on an as needed, time and material basis.
