RE: Proposed Amendment No. 2
Contract No. 2202091
General Maintenance of Grit Collectors
Vendor: Titus Welding Company, Inc.
MOTION
Upon recommendation of Navid Mehram, Chief Operating Officer - Wastewater Operating Services, the Board of Directors (Board) of the Great Lakes Water Authority (GLWA), authorizes the Chief Executive Officer (CEO) to enter into Contract No. 2202091, Proposed Amendment No. 2, “General Maintenance of Grit Collectors” with Titus Welding Company Inc., at an increased cost of $400,000.00 for a total cost not to exceed $1,300,000.00 and an increased duration of 114 days for a total duration of 905 days; and authorizes the CEO to take such other action as may be necessary to accomplish the intent of this vote.
BACKGROUND
The Water Resource Recovery Facility’s preliminary treatment process for Pumpstation No. 1 includes eight (8) grit channels with each channel containing a north and south bay totaling to 16 bays. Each bay employs a chain and flight system that runs along the bottom to remove the settled grit for disposal.
Titus Welding Company has completed repairs to grit channels 1, 4, 5, 6, 7, and 8. The remaining channels left to rebuild are grit channels 2 and 3, which contain #02S, #02N, #03S, and #03N. The chains, buckets, shaft, sprockets, and bearing are worn considerably and require replacement before catastrophic failure occurs.
JUSTIFICATION
The proper operations of the grit channels are critical to ensure grit removal from the influent flow to minimize the grit entering the plant that can cause excessive wear and tear on downstream equipment. The remaining grit channels are worn and past expected life and require rebuilding.
