Manteca is spending $428,642 to place a new roof on the future homeless navigation shelter at 555 Industrial Park Drive.

The Manteca City Council Tuesday awarded Peterson Roofing a $389,674 contract to replace the roof with a $39,968 contingency.

That is in addition to:

*hiring A-1 Remediation Service for $151,716 with a $15.172 contingency fund

*retaining JC Wagner & Associates for an amount up to $150,000, with a 10% contingency of $15,000, to address any additional engineering, design, or structural repair services that may be required during roof replacement.

Last year, the Qualex Building located at 555 Industrial Park Drive sustained significant damage when two sections of the roof collapsed due to excessive rainfall and prolonged ponding of water. Emergency repairs were completed to stabilize the roof and address immediate safety concerns; however, those repairs were temporary and did not resolve the roof's overall deterioration.

As demolition activities began, previously unknown hazardous conditions were discovered within the office portion of the building.

Prolonged water intrusion from the failing roof resulted in extensive mold growth and water damage throughout the interior finishes. B

Based on an inspection conducted by Ostlund Environmental Services, Inc., full remediation of all water- and mold-damaged materials was recommended to protect public health and safety and prevent further deterioration of the building.

Given the extent of the damage, City staff determined that a complete roof replacement is necessary rather than continued patchwork repairs.

Staff solicited three proposals for the roof replacement and recommends awarding the contract to Peterson Roofing in the amount of $389,674, as the lowest responsive and responsible bidder.

The funding is coming from $16 million the city obtained in a state grant to acquire and remodel the former 55,000 square-foot Qualex building for use as a homeless navigation center.
