Phase I: Provided design services for the repairs of 4,600 feet of existing seawall and bulkhead at the SP Area Naval Station, located in Norfolk, Virginia. Constructed in 1941, the original structure had corroded and failed, resulting in material section loss and backfill loss behind the bulkhead. Services included:

• Surveys to identify ground elevations and locate all utilities and storm outfalls.
• Engineering fieldwork to address potential subsurface erosion concerns.
• Phased construction plans so that adjacent aircraft operations would proceed unimpeded.

Phase II: We designed approximately 410,000 SF of aircraft parking apron, including appropriate pavement markings. The design involved phasing and staging areas to ensure adjoining airfield remained operational during construction. Project highlights included:

• World War II concrete pavement was removed, crushed, graded onsite and reused as base material for the new concrete aircraft apron.  This detail satisfied “Sustainable Design” goals for the project.
• New aircraft tie-downs and grounding points were included in the design.
• Antiterrorism/force protection considerations were addressed with the design.
