Explanation
1. BACKGROUND: This legislation authorizes the Director of Public Utilities to modify (Mod #1) an existing engineering agreement with EmNet, LLC for the Real Time Control - Sewer System Optimization, CIP 650009-100002. The goal of RTC (real time control) is to reduce overflows, plant bypasses, and DOSD operational costs. The study identified areas within the collection system that would benefit from RTC, and those that would not. Operational constraints and existing modeling was studied and used to propose the initial RTC implementation plan. This contract modification will add new sensors to the collection system, create visual displays of live data, and demonstrate the live flow conditions of the collection system. Then a RTC dashboard will be created to show the predictive flow conditions for a select portion of the sewer system. A future renewal is planned for expansion of the coverage area and the duration of the predictions. The planning area is the entire service area.
1.1 Amount of additional funds to be expended: $519,832.41
Original Contract $ 741,036.22
Modification 1 $ 519,832.41
CONTRACT TOTAL $1,260,868.63
1.2 Reasons additional goods/services could not be foreseen:
It was the original intent of this contract to include modifications. However, due to the complexity of City’s collection system and ongoing capital improvements, the City was unable to estimate the timing of these modifications, the effort involved, and the associated cost.
After the study was concluded, the City is now able to anticipate the scope of work and provide an estimated cost. There is a plan moving forward to implement RTC in a stepwise manner. This contract will have 1 modification and 1 future renewal. Additional expansion and development is warranted after the modification and renewal, therefore, a new RFP will be issued at that time.
1.3 Reasons other procurement processes are not used:
