The engineering and administration offices occupy the <br />upper floor. An as-built construction description is provided in Exhibit 68. A small skid-mounted <br />shed was added at the foot-bridge entrance to the office building in 2020. <br /> <br />Warehouse <br /> <br />MCC expanded the warehouse facilities by converting the former maintenance shop to warehouse area, <br />adding a third level mezzanine inside the existing building and constructing an office addition. The <br />building is approximately 6,000 square feet on the ground level. Warehouse offices, purchasing offices, <br />and material storage occupy the first floor. Additional material storage and offices are located on the <br />second and third level mezzanines. An as-built construction description is provided in Exhibit 68. <br /> <br />Maintenance Shop <br /> <br />Construction of a maintenance shop was completed in June 1993. The 15,000 square foot shop <br />consists of two levels. The ground floor includes six service bays, including a welding bay and a <br />wash bay. The second level mezzanine, located in the back half of the building includes offices, a <br />library, a lunch-room, and a locker room.

This <br />4,400 square foot, open-front building contains five bays for materials storage. In addition, MCC <br />constructed tire storage racks to the west of the warehouse building, adjacent to an existing bin wall. <br />The racks are constructed of wood cribbing that will be open on all sides and covered by light gage <br />roofing. As-built descriptions of these structures are provided in Exhibit 68. <br /> <br />Surface Shop Building <br /> <br />The surface shop building is used for maintenance of surface equipment. The 4,130 square foot <br />building consists of two service bays, a line-up area and a covered area used for sand and gravel <br />storage. A dozer service facility (approved per MR-229) is planned to be located adjacent to the <br />surface shop building but has not yet been built. It will be utilized to perform maintenance on the <br />larges surface equipment. As-built descriptions of the surface shop facilities are provided in Exhibit 68. <br /> <br />Materials Storage Bench Building
