Subject/Title: Design and Services During Construction for the Water Distribution Telemetry/SCADA System (CIP Project No. 562-5620)

Submitted by: Engineering: J. Stevenson/B. Grewal/P. Eldredge

Approved by: Jon Elam, City Manager

Authorize the City Manager to execute an agreement for an amount not to exceed $271,000 between Electrical and Control System Engineering Inc., and the City of Brentwood to provide design, biddable contract documents and services during construction for the Water Distribution Telemetry/SCADA System, CIP Project No. 562-5620, and authorize the City Manager to execute change orders up to 10% of the contract amount.

No previous actions for this item.

Currently the potable water system is operated manually with the operators spending a good portion of their day turning pumps on and off, obtaining tank levels and other required data. As the City has grown over the years, the number of water facilities required to support the population has grown as well and the above referenced method of operation has become unfeasible. This project will allow the system to be monitored and controlled remotely from one or more locations, and the system can be programmed to run efficiently as one cohesive unit. This system has the potential to pay for itself over a period of time, as energy costs and water purchases can be more closely controlled and optimized. In addition, data will be more readily available and usable for reporting to the various agencies that regulate potable water systems. The completion of this project will allow the City to have a proactive approach to the operations of the water system.

Electrical and Control System Engineering Inc. is the electrical and control systems consultant on the Wastewater Treatment Plant Expansion project and have performed exceptionally well on that project thus far. Their selection to provide design and services during construction was a simple one due to that fact that staff has worked with them previously, they have an extensive knowledge of the tasks at hand, they have an extensive knowledge of the City’s system and they currently have a presence in the City which will provide for more efficient communications between team members.

The scope for this project has been broken down into two categories: services during design and services during construction. The services during design comprise $185,000 of the total amount and include but are not limited to the following:

· Predesign: Perform field investigations of all sites to asses existing facilities, interview operations personnel and prepare draft and final reports outlining the required monitoring and controls, communications, estimated construction costs and implementation, and implementation sequencing and scheduling. This predesign, among other things, will include proposed standards for City water facility instrumentation and control. These standards will provide a baseline for future projects to ensure consistency throughout City facilities.

· Design: Designs for all sites will be performed with the overall construction budget in mind. The designs will be suitable for execution by a qualified contractor experienced in municipal electrical and instrumentation control systems, and the complexity of the work will be limited to ensure that the construction process is quick and not difficult. Submittals will be received at the 50%, 90%, 100% draft and final design stages.

· Other services to be performed during the design phase include but are not limited to construction cost estimating, coordination with adjacent water districts, scheduling and services during bidding.

The services during construction comprise $86,000 of the total amount and include but are not limited to the following:

· Office Engineering: This will consist of consulting with the contractor for design clarifications, responding to requests for information, coordinating, reviewing submittals and preparing all necessary documentation relating to changes or modifications during construction.

· Construction Observation: Jointly observing installation of equipment with City personnel, inspecting factory testing of programmed systems and assistance during installation and startup.

The cost of the Water Distribution Telemetry/SCADA System is authorized in the Capital Improvement Program 2000/05 Budget as Project No. 562-5620.
