DBB, North and Flight Test Apron Repairs, Hill Air Force Base, UT

Repair North & Flight Test Apron near Building 1, Facility 5000, and adjacent shoulder (Facility 5129). Replace existing Portland cement concrete (PCC) slabs in the east half of section A17B with 20’ x 20’ maximum panel sizes, along with full rework of structural base materials to include addition of an aggregate base course with stabilized drainage layer and geotextile filter fabric, as required for seasonal frost conditions, all in accordance with current UFC standards. The project features of the design will not exceed 26,222 square yards of primary and supporting facilities. Work includes a few slabs in adjacent section A24B1 to form a straight work boundary. Protect communication lines buried under southeast part of the apron during construction. Provide anchored tie-downs and pavement markings on new apron pavement. Replace existing shoulder asphalt pavement, along with rework of the shoulder base. Demolition includes removal of existing apron PCC slabs and asphalt shoulder. Facilities will be designed as permanent construction in accordance with the DoD Unified Facilities Criteria (UFC 3-260-02 Pavement Design for Airfields, UFC 3-260-01 Airfield and Heliport Planning and Design, UFC 3-535-01 Visual Air Navigation Facilities), and AFI 32-1042 Standards for Marking Airfields. Asbestos/LBP (lead-based paint) inspection must be completed prior to starting this project. Any asbestos/LBP removal shall be accomplished by a certified asbestos/LBP removal contractor.
