N/A

BACKGROUND:
Water Utilities staff in conjunction with Public Works staff solicited the services of Garland/DBS Inc., a vendor with a U.S. Communities cooperative contract, to assess the condition of all roofs and building envelopes at the Springbrook Water Reclamation Center (SWRC). With the assistance of Garland, staff was able to develop a maintenance plan moving forward to extend the life of the roofs in acceptable condition and replace roofs nearing critical condition. The City Council previously approved the award of Contract 18-191 to replace and repair roofs at four buildings in immediate need at SWRC.

The assessment noted above found the Biosolids Processing Building roof did not need replacement; however, restoration work and minor repairs are necessary to maintain the integrity and prolong the life of the roof.

DISCUSSION:
The restoration work consists of applying a liquid structural membrane to the surface of the existing roof. The roof has survived its expected life of 20 years and by performing the restoration, it is anticipated the life can be extended another 10 to 15 years at less than half the estimated cost of a full replacement.

In addition to the roof restoration, the repair work includes the replacement of the access hatch f...
