Full report
Gardner City Council has authorised a $76,500 contract with Cornerstone Construction Solutions for replacement of the roof at the Hillsdale Water Treatment Plant, moving to address deterioration across roof sections of different ages.
The October 19 approval covers the Hillsdale Water Treatment Plant Roof Replacement project, identified as WA7008. Funding is available through the Water Fund's water-treatment operations and maintenance budget.
City staff said the existing roof combines areas dating to the plant's 2005 expansion with repairs made to the original plant roof. Multiple repairs to skylights, alongside some wood rot, have created the need for the work.
Cornerstone submitted the lowest of four bids received by the Utilities Department. Its $76,500 proposal was $430 below the $76,930 bid from McCool Roofing, while American Roofing bid $79,973 and Blue Ribbon Investment bid $100,705.
The bid documents specify removal and disposal of 15,000 square feet of composition shingles, followed by installation of 15,000 square feet of Class 4 shingle roofing and synthetic underlayment. The scope also includes ice and water barrier, flashing and pipe-jack replacement, continuous ridge ventilation, replacement of five known sheets of wood decking, restoration and a $7,500 owner allowance.
Under the agreement, work cannot begin until the city issues a notice to proceed. The contractor must submit an estimated progress schedule within 10 days of the agreement's effective date and before starting work. The contract sets liquidated damages at $200 per calendar day for late completion for contracts valued between $50,001 and $100,000.
