This project will serve as the new District 11 Highway Department Maintenance Facility replacing an existing salt structure located at another site in Whitley County. This project consists of a new 3,000-ton capacity salt storage building with a 10 -0" tall reinforced concrete walls bearing on an asphalt slab, with pockets of these walls extending into the subgrade to prevent sliding. Concrete buttresses will be placed along the straight run of wall to resist lateral forces imposed on the structure. On top of the concrete will be a pre-fabricated metal truss structure sheathed with a fabric cover, of which the design and installation is outside the scope of this project (NIC by Owner). The new salt structure is a component of another larger project that includes three structures at the upper site at this same location along with complete site civil and site utility work. These five components of this project are the following: C - Civil, SU - Site Utilities, ESS - Equipment Storage Shed, MF - Maintenance Facility, & SEO - Section Engineer Office. A second existing salt structure will be moved to the lower site next to the new salt structure from another site later by the user agency (NIC). The following items will be Owner provided Owner installed (Not-in-Contract): 1.ASPHALT PAD - Will be installed by Owner for the new Salt Structure at the Lower Site location (NIC) - Pad will be in place before start of project. 2.PMCS ROOF STRUCTURE - Owner will provide and install PMCS Roof Structure on top of New Salt Structure.
