This document is a 35% design-phase construction drawing set for repair and rehabilitation work on Perimeter Drive and Industrial Boulevard at Tinker Air Force Base, Oklahoma.

The project scope includes full-depth asphalt pavement repairs on Industrial Boulevard across three sections spanning approximately 23 station points, complete demolition and reconstruction of Perimeter Drive with new 6-inch asphalt concrete pavement, installation of new storm drainage systems (including reinforced concrete pipe and precast concrete flume), replacement of curb and gutter sections, grading and drainage improvements, and pavement marking installation. The work encompasses approximately 1,496 square feet of full-depth repairs on Industrial Boulevard and reconstruction of Perimeter Drive from station 6+00 to 29+00. Construction details specify 4 inches of Type "A" asphalt concrete over 6 inches of modified subgrade and 6 inches of stabilized aggregate base. The project requires installation of new surface inlets with precast concrete collars, conversion of existing cast iron curb inlets, new 4-inch solid and dashed white line pavement markings, 4-inch double yellow centerline markings, and associated drainage swales. Contractor responsibilities include all erosion and sediment control measures, protection of storm water inlets, removal and off-base disposal of demolition materials, repair of any damage to existing facilities at no additional cost, and verification of existing utility and facility locations prior to construction. The drawings are prepared for the 72nd Air Base Wing Civil Engineer Directorate at Tinker Air Force Base and include standard civil abbreviations, symbols, and references to Oklahoma Department of Transportation specifications for materials and construction standards.
