Explanation
1. BACKGROUND
This ordinance authorizes the Director of Public Utilities to modify the service contract with Synagro Central, LLC, for the Parsons Avenue Water Plant (PAWP) Residuals Removal and Disposal - Lagoon 3 project, CIP #690566-100001, in an amount up to $12,000,000.00.
The purpose of the PAWP Residuals Removal and Disposal - Lagoon 3 project is to provide services to remove, transport, and dispose of the water treatment residuals and grit-laden material from Lagoon 3. Residuals are the waste materials removed during the drinking water purification process. Some of these materials will be disposed in a beneficial reuse manner as fertilizer or compost, while some of the materials will be taken to landfills for disposal. This disposal preserves the existing lagoon to continue to be used for residual storage. The cost of emptying Lagoon 3 of residuals is much less than it would cost to buy new land and build another residuals storage lagoon.
This ordinance will authorize a contract modification in the amount of up to $12,000,000.00 for the Parsons Avenue Water Plant (PAWP) Residuals Removal and Disposal - Lagoon 3 project. The scope of work for the contract is not changing. This is a planned modification to provide funding for a multi-year contract.
The Community Planning Area is 99 - Citywide.
1.1 Estimated Cost of Project
The bid amount and proposed award amount was $41,379,583.30, including a 10% construction contingency amount that will be utilized to fund needed and approved changes in the work. An initial contract was issued and there are three anticipated modifications; however, construction exigency might later compel modification of this contract, if unforeseen difficulties are encountered.
