Hillis-Carnes was contracted to provide Geotechnical Engineering and Construction Materials Testing and Inspection services for Phase 1 of the multi-phased development of the Annapolis Junction Town Center, located in Savage, Maryland. This phase included the construction of a four-level parking garage providing 704 parking spaces for commuters at the Savage MARC Rail Station.

The scope of services provided by Hillis-Carnes included dilatometer testing (DMT) and standard penetration test (SPT) borings, soil laboratory testing, and geotechnical engineering services during the design phases of the project. Testing and inspections of soils/earthwork, concrete, steel/precast installation, and pavement were provided during the construction phases. The testing and inspections of the soils/earthwork consisted of the mass grading/fill placement, utilities, stormwater management facilities, and foundations-spread footings. Testing and inspection services of the concrete included reinforcement and formwork inspections, sampling and field tests for cast-in-place walls, footings, and slabs. Field tests included slump, temperature, air entrainments and mix duration, as well as casting cylinders to test for compressive strength. The reinforcing steel was checked for proper size, placement, spacing, tying, lap length and cleanliness prior to the placement of concrete using the structural plans and approved shop drawings as a reference. Hillis-Carnes also provided a structural steel field inspection as well as checked all pre-cast concrete installation.
