About this file

Written by GovTribe AI · Mar 12, 2026

This file is a set of architectural and engineering drawings prepared by OHM Advisors for the City of Livonia, Michigan, detailing grading and site preparation for the construction of a greenhouse facility at Garfield School. The contract scope includes site grading, drainage infrastructure installation, concrete pad preparation (41' x 66'), construction fencing, turf restoration, and coordination with utility services. The project involves the installation of a 3-inch PVC drainage system with floor drains, a bioswale for stormwater management, concrete walkways meeting ADA requirements, tree protection measures, and coordination of water and natural gas service connections. The site layout indicates the greenhouse location adjacent to an existing gravel parking area on the Garfield School campus in Livonia, Michigan. The drawings were originally prepared on February 7, 2020, and revised on September 23, 2021, per Livonia Public Schools request. The contract specifies that greenhouse procurement, delivery, and construction will be completed under a separate contract, with greenhouse plans to be provided by Livonia Public Schools.

The project contractor is responsible for all site preparation, including removal and salvage of existing gravel, subgrade preparation, installation of drainage infrastructure with specific invert elevations and slopes, concrete placement with control and isolation joints, and restoration of turf areas. Key requirements include coordination with Miss Dig (Underground Service Alert) a minimum of three days prior to construction, tree protection fencing at the drip line of all trees to remain, maintenance of existing parking lot access, and repair of any damage to adjacent areas at contractor expense. The contractor must employ licensed and insured workers, maintain all drainage facilities during construction, and immediately report any discrepancies between field conditions and drawings to the owner's representative. All materials, including geotextile liners, open-graded aggregate, and concrete specifications, require engineer review and approval prior to installation.
