Explanation

1.0 BACKGROUND: This Ordinance authorizes the Director of Public Utilities to modify and increase the professional engineering services agreement with Brown and Caldwell for the Hap Cremean Water Plant (HCWP) Lime Slurry Disposal Line Condition Assessment Project, Division of Water Contract No. 2041.

The original project consisted of three phases. Each phase was intended to build confidence in the capability of the in-line inspection technology before moving to the next phase.

Phases 1 and 2 were legislated under Ordinance No. 0760-2014, passed April 28, 2014. Phase 1 consisted of the condition assessment of a 12” water distribution main using an in-line inspection tool. Phase 2 consisted of the condition assessment of the DRWP 14” lime slurry disposal line and a pilot section of the HCWP 12” lime slurry disposal line.

Phase 3 was legislated under Ordinance No. 2187-2016, passed October 3, 2016. Phase 3 consisted of the condition assessment of a 2 mile section and a 3 mile section of the HCWP lime slurry disposal line between the end of Phase 2 and the McKinley Quarry.

Due to the successful assessment of the previous phases, additional areas along the length of the lime slurry disposal line need evaluated to fully identify the areas that pose the greatest potential risk of failure. In addition to the condition assessment of the additional areas, a rehabilitation strategy will need to be conducted so that a future CIP project can be designed and constructed to address the areas that are posing the greatest risk of failure. This work will be performed under Modification Number 2 (current) to authorize Phase 4.

The planning area is “City Wide” because this project serves multiple planning areas.

1.1 Amount of additional funds to be expended: $680,000.08
Original Contract Amount: $1,336,013.71 (EL015711)
Modification No. 1: $1,011,279.78 ...
