Each drawing shall indicate project title, project number, array identification and location, A/E firm, A/E's address and/or phone number, contract number, drawing title, drawing type, drawing number, and key plan. A cover sheet shall be provided and shall include a list of the drawings, legend, vicinity map, and location map in addition to all items required for each drawing. Each A/E submission shall be clearly dated and labeled (e.g. 75% Design Development Submission, 100% Check Set Submission, Construction Document Submission, As-Built Drawings, etc.). Each drawing sheet submitted shall include a graphic scale in the lower right-hand portion of the sheet. The final set shall be stamped by a registered engineer and/or registered architect for the state in which the building/carport is located. At a minimum, the following drawings are required: i. Site plan including utility locations and connections – shall show staging and phasing requirements. ii. Electrical plans – including single line diagram and utility interconnection. iii. Electrical details. iv. Roof plan, if applicable – showing the full layout of the system and detailing any obstacles that must be permanently or temporarily removed or relocated. v. Array support and mounting details, including cross-sections of how the array will be mounted to any supports, ballasts, or piles. vi. Structural loading calculations. For roof and ground mount installations, live and dead loads must be assessed. Rooftop installation designs must be approved and stamped by a licensed structural engineer. vii. Water proofing details viii. Snow removal details and practices including relevant bollard placement and equipment marketers/flags accounting for potential snow drifting. ix. Any drawings that may be required to install a complete project. c. Specifically address the means to keep the existing building accessible and operational by means of relocation and / or phasing. d. For all ground mount installations, the drawings must account for cyclical frost heave. The construction drawings must clearly indicate and prove how the proposed design will endure freeze and thaw cycles common in Minnesota. e. The State, at its discretion, may reject a slab-on-grade ground mounted design. The Contractor may only continue engineering a slab-on-grade design with the consent of the State. f. All ground mount foundations and footings must be approved by the ordering entity, and the design must indicate requirements for soil corrections under slab: 1) depth of removal of soils, 2) extent and specifications of compacted base course and subgrade, 3) extent and specifications of drainage layer if required. i.

Consolidate all concrete by vibrating. 5. All concrete shown shall be reinforced. 6. Provide reinforcing steel grade and ASTM standards required. 7. Provide chart for lap splice lengths. 8. Indicate minimum concrete cover for reinforcement. 9. Mix designs shall incorporate admixtures as appropriate for environmental conditions.
