Title
Consider and take action on a resolution authorizing a construction contract with ISJ Underground Utilities, LLC for the Sanitary Sewer Annual Rehab - East Main 24-inch Force Main Replacement Project (WW1801I) in an amount not to exceed $3,247,245, with an additional Work Change Directive budget not to exceed $324,000, and authorizing a construction material testing services contract with Terracon Consultants in an amount not to exceed $29,980 resulting in a total construction budget not to exceed $3,601,225 (Executive Director of Capital Projects)
Background:
Approval of this resolution will authorize the award of the construction contract to ISJ Underground Utilities, LLC for the construction of the Sanitary Sewer Annual Rehab - East Main 24-inch Force Main Replacement Project (WW1801I) in an amount not to exceed $3,247,245, authorizing an additional Work Change Directive budget not to exceed $324,000, and authorizing a construction material testing services contract with Terracon Consultants in an amount not to exceed $29,980, for a total construction budget of $3,601,225.
This project is part of the City’s on-going Sanitary Sewer Annual Rehabilitation Program, which consists of engineering evaluation and strategic rehabilitation of City’s sanitary sewer systems. This project includes replacement of approximately 5,300 linear feet of an existing 24-inch diameter sanitary sewer force main serving the East Main Lift Station along FM 2094. The project also includes grout fill abandonment of the existing force main, and all labor, equipment, materials and incidentals required for the project.
The Existing 24” Force Main is over 40 years old and serves the East Main lift station. This station is a general benefit lift station, receiving flows from 12 sub basins via smaller lift stations and gravity lines. Force Main Pipe is of ductile iron material which is more susceptible to deterioration due to gases in line as pipe nears the end of its useful life. Recent leakage along FM 2094 at Davis Road showed major deterioration along crown of the pipe (see Attachment 5). The major emergency repair included replacement of sections of the pipe, wet hauling of sewage from the lift station while repairs were underway, pavement panel removal and replacement, and traffic control. A potential future leak in deeper sections or under FM 2094 could have major environmental, traffic, and repair impacts associated with it. City staff has expedited the bidding process after completion of the bid documents for total replacement of line with PVC pipe, TxDOT permitting, USACE review of the Robinson Bayou crossing, and easement acquisition.
Five (5) bids were received on August 27, 2024 (Bid No. 24-050). Two bids were disqualified due to lack of hard copy Bid Bond submittal at the time of bid opening. Out of the three (3) qualified bids and based on City’s A+B bidding method and contract times received, ISJ Underground Utilities, LLC submitted the lowest responsible and responsive cost value base bid plus extra work items in the amount of $3,247,245, and 150 calendar days from notice to proceed to final completion. Attached is the City’s engineering consultant’s recommendation of award letter and the bid tabulation.
