MEETING DATE: APRIL 3, 2018
SUBJECT: CONSTRUCTION SERVICES CONTRACT — WASTEWATER
TREATMENT PLANT TRAIN 1 CIRCULAR CLARIFIERS
REPLACEMENT PROJECT AND APPROPRIATION
ORDINANCE
RECOMMENDATION:
City Council consider:
• Adopting an ordinance appropriating $608,300 (includes 10% contingency) in the
Utility Enterprise Capital Fund using released impact fees of $484,000 and FY15
Certificate of Obligation Funds of $124,300 for the replacement of the Wastewater
Treatment Plant Train 1 Circular Clarifiers.
• Awarding the construction contract for the Wastewater Treatment Plant Train 1
Circular Clarifiers to AIITech Engineering Corporation in the amount of $553,000;
and
• Authorizing staff to execute said contract and take any necessary action.
FUNDING:
Upon approval of the attached appropriation ordinance, $608,300 will be available in the
Utility Enterprise Capital Fund in account 201-43370-534-000-180096.
BACKGROUND:
The WWTP has three trains, each of which can be operated independently of the others.
However, during normal operations, two of three trains must be operational. The proposed
project is to make significant replacements in the train one clarifier.
Bids were opened on February 16, 2018 with five bids received:
J. S. Haren Company (Rejected)
AIITech Enigneering Corporation
Red River Construction
Gracon Construction
Bar Constructors, Inc.
$ 527,000
$ 553,000
$ 616,500
$ 666,000
$ 806,982
Bids have been reviewed and references checked. Based on this information, staff
recommends the rejection of J. S. Haren Company due to delay issues on the firm's other
current projects. Delays on this project would have a compounding effect on other projects
at the WWTP such as the extensive electrical project currently underway.
Staff recommends Council to award the contract to AIITech Engineering Corporation to
maintain the project schedules in the plant.
The contract schedule for the project establishes a construction time of 280 calendar days.
Staff recommends approval.
