Title
APPROVE AN AMENDMENT TO THE CONTRACT FOR DESIGN AND CONSTRUCTION OVERSIGHT OF WATER TREATMENT PLANT NO. 4, IMPROVEMENT PROJECT NO. 19-11 WITH BARR ENGINEERING/BOLTON&MENK, INC.
Background
The consultant team of Barr Engineering and Bolton & Menk was awarded the contract for design and construction support of the new Water Treatment Plant No. 4 Improvement Project on May 17, 2018.
The team has worked diligently over the past year to develop an excellent design that has met all of the requests and needs of the city. The team has also performed on number of additional requests and extras that came up during the development of the project. These include: adding solar to the building, additional stormwater management components such as green roofs and rainwater reuse, full span garage roof system, expansion of the civil site work to extend further west on the property, adding the police break room, a water fill station at the Tower, additional wetland permitting work, extra site visits, and review meetings. In order to improve the construction timelines and RCWD requirements, the completion date for the project was also extended by five months, which in turn extends the construction support time they will need to be on site. Details and cost breakdown of this extra work is included in the attached request.
Staff has reviewed the request in detail and is in agreement that all costs are reasonable. It is the extra effort that was put in on the front end of this project that created such a tight project resulting in very close bids and a project cost savings of nearly $3M over the anticipated expense to build this plant.
City Council is also asked to approve a contract amendment in the amount of $432,374.00 for the additional scope to complete the project. The funding source for this project is Water Utilities and there are sufficient funds to cover these costs.
Recommendation
By motion, adopt the resolution.
