KCI provided site/civil engineering services to the Army and Air Force Exchange Service (AAFES) as a sub-consultant to build a new shoppette facility at Fort Lee, Virginia, located on a seven acre site and 97,000 SF parking area for 100 vehicles. KCI’s scope of services included preparation of a topographic survey, subsurface exploration, geotechnical evaluation, landscape design, civil engineering and construction administration.
Provided stormwater management, surveys, civil and landscape architecture services for a 21,000 SF shopping center which included a 12-bay gas station, car wash, car repair, a shallow infiltration facility, 100+ parking spaces, loading dock, three drive lanes, and dry cleaning operation. Preliminary landscape and site layout plans were designed and review for approval by AAFES. Following approval, KCI prepared construction documents and specifications to include an overall site and grading plan, storm-water management plans, sanitary sewer plans, domestic water plans, erosion and sediment control plans and a final landscape plan. KCI’s designs preserved an existing 60” oak tree on the site and landscape screening consisted of deciduous and ornamental trees, evergreens, shrubbery and ground cover. KCI participated in construction administration services including; preparation of bid packages, participation in the bidding and negotiation process, review of request for information, review and approval of change orders, and construction inspection services.
Using soil borings and geotechnical laboratory testing, KCI was able to evaluate the general subsurface condition of the site, with respect to the foundation design, ground supported slab, earthwork, flexible and rigid pavement sections, infiltration, and other geotechnical concerns. The field exploration results indicated that the site could be developed for the proposed structure. Recommendations included undercutting of fill and high plasticity materials in structural and pavement areas and proper monitoring of new fill operations, footing excavations, and concrete placement in all structural areas.
Regarding the stormwater management infiltration facilities, it was recommended that infiltration facilities be located only in areas where the bottom of the structure was to be 2 to 4 feet above the seasonally high groundwater level and/or bedrock.
