Explanation
1. BACKGROUND: This Ordinance authorizes the Director of Public Utilities to modify and increase the construction contract with Kokosing Construction Company, Inc. for the Hap Cremean Water Plant (HCWP) Treatment Improvements Project, for the Division of Water, Contract No. 1151.
The purpose of the original contract was to upgrade the treatment processes at the Hap Cremean Water Plant. The contract called for upgrading all filters and electrical services, modifications of basins, rerouting of chemical applications, and implementation of ozone treatment.
Due to the timing of required reductions in plant capacity for elements of the construction project and coordination with additional construction projects at the other two water treatment plants, construction had to commence prior to September 2012. Because of the limited construction window, the project required enhancements to the existing design elements and additional funding was necessary.
Modifications to the original contract include:
Proposed RFP-005 LEED certification of new Ozone Production Facility $2,500,000 (estimated)
In order to attain certification for Leadership in Energy & Environmental Design (LEED) a number of changes had to be made with respect to improved Heating, Ventilation, Air Conditioning (HVAC) efficiency, architectural material changes, landscaping, and stormwater modifications. Additionally, construction activities had to be modified by increasing the percentage of construction debris to be recycled, additional record keeping and reporting by the contractor, and assistance with fundamental commissioning of building energy systems.
Proposed RFP-010 Ozone basin structural modification $ 2,500,000 (estimated)
Revision of the current design to a sealed sample discharge system with a higher discharge flow capacity, including variable frequency drive-controlled duty/standby vertical pumps in Injection Gallery. Addition of a small calcium thiosulfate feed line for ozo...
