About this file
This is a specification document for the Garfield School Greenhouse project in the City of Livonia, Michigan, prepared by OHM Advisors. The project encompasses the design and construction of a 30' x 50' greenhouse facility with associated site improvements located at the Garfield School campus. The specifications detail the complete site plan, including the greenhouse structure, proposed raised planters measuring 6' x 12' x 3' in height with minimum 6-foot spacing, a 1,450 square foot bioswale for stormwater management, orchard trees (size and species to be determined by the owner), and compacted gravel aisles throughout the facility. The site plan incorporates water and gas service connections, floor drainage systems, and connections to existing storm sewer infrastructure. The project was prepared under the supervision of Ben Weaver, PLA, with a project number of 0090-18-0080 and a document date of December 17, 2019.
The specifications provide comprehensive construction details for all site components, including planter construction utilizing 4x4 pressure-treated posts, 2x8 cedar caps, 2.5" x 12" corrugated stainless steel side walls, EPDM rubber liners with perforated weep holes, and cedar horizontal beams. Tree planting requirements are detailed with staking plans, mulching specifications, and pruning guidelines. The bioswale and rain garden components include specifications for open-graded aggregate, permeable geotextile liners, corrugated polyethylene under-drain pipes, and planting mix requirements with maximum clay content of 5 percent and organic content between 1.5 and 3.0 percent. All hardware is specified to be hot-dipped galvanized, and all cedar materials are to be stained in a natural color as determined by the owner. Contractor submission of material samples for engineer review and approval is required prior to installation.
