INTRODUCTION Salem Area Mass Transit District and Marion County (owners) are soliciting proposals for construction laboratory testing and inspection services related to the Courthouse Square development in Salem, Oregon . This structure consists of a five (5) story concrete, flat-plate slab system. The ground floor, and all elevated slabs incorporate a post-tensioned concrete system. The foundation consists of a concrete slab-on-grade, with independent column footing and a perimeter retaining wall. The lateral force resisting system for the building consists of two (2) shearvvall-core elements at each main stairway. Reinforced concrete shearwalls provide lateral resistance, supported by reinforced mat foundations. The columns and main floor slab at the northern portion of the site have been designed for future development. A bonded post-tensioned slab has been provided to allow for a future 4- 5 story wood frame structure. In addition, the columns have been sized for a five (5) story concrete structure, with splice placed provided. The main floor slab has been isotated from the bus lanes.
