About this file
This addendum modifies the specifications and drawings for solicitation number FA520523D0005, a requirements contract for roads, pavements, and miscellaneous civil work at Misawa Air Base in Japan.
The addendum revises the specifications by removing and adding line item numbers for excavation, earthwork, drainage, utility, sidewalk, curb, and pavement removal and construction work. It also modifies the descriptions of several existing line items. The drawings are changed by removing areas delineated in red and clarifying that certain line item numbers apply to work in multi-family housing carport areas from parking lots to housing units, excluding roadways. The contractor must coordinate work in phases to minimize resident impact, with each phase including 16 parking lots. The revised specifications and drawings are attached.
