Attachment 6 - SBML 1052018 - 100 percent drawings part 3.pdf

This document is a 100% Design Submittal for the Repair Taxiway Alpha & Bravo-NAF project at Air Mobility Command, Joint Base Charleston – Air Base. The submittal includes comprehensive engineering drawings and specifications for taxiway rehabilitation work.

The project scope encompasses repair and reconstruction of Taxiway Alpha and Taxiway Bravo, including new asphalt concrete mill and overlay sections, asphalt access road sections, pavement tie-in to existing pavement, bituminous pavement crack repair, and storm drainage improvements. Detailed design plans address taxiway cross sections with traffic-rated drainage structures, electrical systems including lighting and signage, erosion control measures with silt fence and temporary gravel construction entrances, and permanent seeding specifications for disturbed areas. The design includes new asphalt concrete mill and overlay at variable depths, new asphalt concrete pavement sections, and maintenance of existing runway interfaces. Drainage details specify traffic-rated precast structures, manhole step details, and collection pipe outfall headwall designs. Erosion control plans document three sequential phases of construction: initial, intermediate, and final phases, with designated temporary seeding and permanent vegetation areas. Civil legend indicates temporary seeding, permanent seeding, disturbed areas, temporary construction entrance, silt fence rock inlet outlets, and limits of construction. The electrical design provides legend and general notes addressing safety requirements, spare parts specifications, and comprehensive installation standards for all electrical components throughout the taxiway system.
