NAVFAC Building 107 & 108 Paving Repair NSA-Mechanicsburg Work Order No. 1750878 The project consists of rehabilitation of a portion of the road/parking surface between Buildings 107& 108 at NSA Mechanicsburg. This project covers the northern end of the 100 "Block" of H Street/Track. This is the area between Buildings 107 and 108 and First Avenues and the crossover bridge between the building. The approximate area is delineated on the sketch in Part 6 Attachments. Existing gravel driving and storage areas shall be repaired via full depth reconstruction consisting of removal of old railroad ballast, a prepared subgrade, new aggregate base course, necessary drainage improvements, and reinforced Portland cement concrete paved area designed for tractor trailer loads and heavy forklift traffic. New pavement markings and signage are to be provided, these will be limited to signage and markings at the entrance and exit. Where possible, namely in areas around First Avenue, some areas should be converted to vegetated rain gardens with a sump (approximately 600 square feet), filter media, underdrain, liner, and connection to the existing storm sewer. An existing porous underdrain running the length of the project area will need to be removed and appropriate drainage installed. The site grading is intended to be reworked to provide necessary to provide good drainage to the existing storm sewer and proposed rain gardens. Any existing storm sewer inlets will require a new top collar and grate installed.
