Title
Resolution for Approval of Change Order No. 2 to the Contract for the Lime Feed System Improvements Project with Irish Construction Company ($177,939.18)
Memorandum
This memorandum and resolution requests approval of Change Order No. 2 to the contract with Irish Construction Company for the Lime Feed System Improvements in the amount of $177,939.18.
This project includes replacing three lime slakers and modifying the associated lime storage bins at the Water Treatment Plant (WTP). The existing lime slakers are in poor condition and were identified during the WTP Facilities Master Plan - 2006 as one of the highest priority capital improvements. The lime slakers are some of the most critical pieces of equipment at the WTP. Without operating slakers, the treatment process is ineffective and the WTP would not be able to meet state drinking water standards.
Council approved the contract with Irish Construction Company for $2,895,000.00 and contingency in the amount of $300,000.00 in November 2009 as part of Resolution No. R-09-463 to complete this work. In June 2012, Change Order No. 1 for a value of $299,369.46 was approved by the City Administrator. Change Order No. 2 will exhaust the contingency for this project, thus requiring Council to authorize for this Amendment.
Change Order No. 2 includes the following additional work:
· Modifications to Lime Slaking System 1 to address grit removal problems;
· Platform modification to accommodate additional pump;
· Time extension to address system modifications for enhanced grit removal;
· Lime slurry hoses;
· Electrical modifications to accommodate additional pumps and variable frequency drives; and
· Concrete modifications for new pump bases.
It is recommended that Change Order No. 2 to the contract with Irish Construction Company in the amount of $177,939.18 be approved.
Irish Construction Company received Human Rights approval on May 31, 2012, and complies with the living wage ordinance.
