Explanation
1. BACKGROUND
This ordinance authorizes the Director of Public Utilities to enter into a construction contract with EN-Tech Corp., via the City’s Invitation for Bid process for the Large Diameter Sewer Rehabilitation - Alum Creek Trunk South Section/Deshler Tunnel-Alum Creek Interceptor Sewer/Truro Sewers (hereafter referred to as Alum Creek Trunk South (Phase 1)) project, CIP #650725-100004, in an amount up to $30,559,381.60; and to encumber funds with the Department of Public Service for construction prevailing wage services in an amount up to $2,000.00. (for a total expenditure of $30,561,381.60).
This sewer rehabilitation project is located almost entirely within Three Creeks Metro Park. A previous condition assessment of the sewer revealed it is in poor structural condition and in need of rehabilitation. This project will rehabilitate approximately 8,431 lineal feet of 102-inch diameter reinforced concrete pipe via shotcrete methods. Shotcrete is a method of applying concrete projected at high velocity onto a surface, giving the sewer pipe the hardened properties of conventional cast-in-place concrete. This method is less expensive than cast-in-place concrete and is expected to extend the life of the sewer pipe a minimum of 50 years.
The Community Area for this ordinance will be 64, Far South.
TIMELINE: Contract work is required to be completed in a manner acceptable to the City within 720 days from the date that a Notice to Proceed (NTP) is given by the City.
ESTIMATED COST OF PROJECT: The bid amount and proposed award amount is $30,559,381.60, including a 10% construction contingency amount that will be utilized to fund needed and approved changes in the work. No contract modifications are anticipated at this time; however, construction exigency might later compel modification of this contract, if unforeseen difficulties are encountered.
