Title
Discuss and consider action to award a construction contract for repairs to the Lake Pflugerville Pump Station and authorizing the City Manager to execute same.
Summary
On Thursday morning, May 1, 2014, utility staff employees doing a routine check of the Lake Pflugerville Pump Station observed large amounts of water bubbling up through the ground around the building. This pump station pushes water from Lake Pflugerville to the City's Water Treatment Plant. Without this pump station in operation, the water treatment plant has no water to treat.
The leaks were significant enough that we had to discontinue use of the pump station. To assure that Pflugerville customers had water, we opened and closed valves around the City so that we could serve the entire City with our two water wells. We contacted Manville and they agreed to temporarily suspend taking water from the City under our two wholesale agreements with Manville. They were taking 1.5 million gallons per day, which accounted for 25% of the water we produced on April 30. We also contacted the Travis County Emergency Services District #2 and asked them to avoid any hydrant flow testing or any exercises that would use large quantities of water. Our construction inspection department asked our capital improvement program (CIP) contractors and subdivision developers to not flush any water lines under construction until next week. By making these requests, we were able to fully serve our retail water customers at this time with well water only.
Significant water was present along the west side of the building as well as in vaults to the south of the building accessing the discharge pipe connecting the pump station to the water treatment plant. Because of the critical role of this pump station to our ability to provide water, we treated the investigation and repair of this facility as an emergency. The size of the pipes (up to 48" in diameter) connecting to this pump station and the depth of the pipes (up to 22' deep) are beyond the capabilities of our Utility Department Staff to repair.
Status
The City's engineer, Freese & Nichols, Inc., provided staff a preliminary findings report on May 16, 2014 and 95% plans and specifications for the pump station repairs were provided to staff on May 23, 2014. Freese and Nichols, Inc. then provided bid plans and specifications to the City and to three pre-selected contractors on May 30, 2014. The contractors pre-selected for this project were Hansen Contracting (Pflugerville, Texas), Archer Western (Irving, Texas) and Cunningham Contractors (Georgetown, Texas). These are reputable firms who have experience with facilities projects in Texas. Bids will be prepared the week of June 2, 2014 and submitted on June 6, 2014. Staff will provide a construction bid analysis and recommendation to the Council at the meeting.
Prior City Council Action
On May 13, the Council approved a professional services agreement with Freese & Nichols, Inc. for engineering and design services for the Lake Pflugerville Pump Station Improvements. The Council also approved a budget of $750,000 for the emergency response, design and repair of the Pflugerville Pump Station. On May 27, the Council approved a resolution ratifying the Lake Pflugerville Pump Station Disaster Declaration.
Deadline for City Council Action
