DC ANG Architectural/Engineering Contract IDQ

Location: Maryland

Client: D.C. Air National Guard

Services: Mechanical engineering, electrical engineering, hydrologic/hydraulic engineering, environmental engineering, structural engineering, construction inspection

Under two consecutive, multi-year contracts, KCI provided architectural/engineering services for the design and upgrade of buildings, maintenance facilities, hangars, and support facilities, including investigations, studies, design, and construction phase services at an Air Force Base. The scope of services provided included: fire protection, electrical engineering, building renovation, stormwater management, wastewater management, structural design, mechanical engineering, and construction inspection. Completed tasks included:

Hangars Study and Renovations. Work on multiple projects included investigating, analyzing, and recommending solutions to specific code deficiencies and client needs for egress, fire separation, hazardous containment, fire suppression, detection, and alarm systems; electrical power systems; design and documentation of exterior painting for hangars totaling approximately 71,000 SF; and plans and specifications for roof repairs and alterations of two 38,000 square foot hangars, including polyurethane foam roofing and standard seam metal roofing.

Alter Squadron Facility, Building. Interior renovation of a 2,400 square foot office included sensitive life support workroom, training areas, and equipment storage. The life support workroom and storage room were designed to be protected areas. The training areas included an egress trainer and a harness trainer. A new overhead rolling door provided to allow access for large training equipment. Design included new partitions, casework, finishes, plumbing, HVAC, and electrical work including all new lighting.

Parachute Loft Flooring Investigation and Design. KCI designed new floors in the parachute loft to provide a new storage room at the second floor. Work included structural design, architectural finishes, and electrical power and lighting.

Stormwater Management Tasks. The project involved rehabilitation of several taxiways and aprons for an Air Force Base. The work included civil/site design, pavement rehabilitation, drainage, stormwater management, and erosion and sediment control design. The existing PCC pavement structure exhibited severe alligator cracking resulting from a combination of loading and subsurface drainage problems. KCI performed pavement borings and designed a pavement section to withstand the loadings from the aircraft and service vehicles. In addition, the subsurface and surface drainage characteristics were investigated. Groundwater levels and surface water drainage paths were established.

The civil design included the replacement/repair of several taxiways and aprons. Grading was established to provide positive surface drainage. Under drains were provided to accommodate areas of high groundwater. During the design process, the State of Maryland promulgated new Stormwater Management and Erosion & Sediment Control guidelines. KCI retrofitted the existing design to accommodate the new water quality and quantity regulations and provided detailed, phased erosion and sediment control plans.
