2026 KCTC-E Greenhouse Roof Replacement

Kent Intermediate School District is soliciting sealed bids for greenhouse roof replacement at the Kent Career Technical Center under the 2026 KCTC-E Greenhouse Roof Replacement, with bids due November 23, 2026 at 1:00 p.m. Kent ISD reserves the right to restrict bidding to Michigan-based businesses only, so in-state status is an eligibility filter. Amendment 1 is the governing document in the file set.

The work removes existing glass greenhouse roof panels from three adjoining gable roof structures, each approximately 35 feet wide by 105 feet long, at 1655 E. Beltline Ave. NE, Grand Rapids, Michigan. The contractor installs approximately 108 sheets of 8mm clear twin wall polycarbonate panels (71.25 inches by 20 feet) with glazing framing, H-extrusions, and rubber gaskets, and also provides site protection and final cleanup. Completion is scheduled between May 31, 2027 and June 30, 2027.

Bids must include material and labor pricing on the required pricing sheet, certificates of insurance, an Iran Economic Sanctions Act Affidavit, and a Familial Relationship Disclosure Statement. Required coverage includes workers' compensation (Statutory Coverage A and $300,000 Coverage B), comprehensive general liability ($1,000,000 each occurrence and $2,000,000 general aggregate), and business automobile liability ($500,000 each). All contractor employees must pass background checks and comply with strict behavioral standards on school property. The successful contractor provides a 10-year manufacturer warranty on the polycarbonate panels and a minimum one-year workmanship warranty covering installation defects, leaks, and panel attachment issues.

Kent ISD is not obligated to accept the lowest bid. Bids are delivered to the Kent ISD Maintenance Building at 1655 East Beltline NE and opened publicly immediately after the deadline. The Kent ISD Board intends to formally award the contract at its December 14, 2026 Board Meeting. Payment is made upon completion of services, and the contractor is responsible for any damages caused during the project.
