RE:

 

 

Authorize the City Manager to execute Supplemental Agreement No.4 in the amount of $45,000.00 for continued Construction Phase Engineering Services for Project UT0701DS Kaw Water Treatment Plant Transmission Main

 

Background

The 2003 Water Master Plan identified projects to address the required increase in capacity and the addition of redundant facilities related to the transmission of finished drinking water from the Kaw Water Treatment Plant (WTP) to the southeast Lawrence area and a second watermain crossing of the Kansas River to North Lawrence.

 

The Integrated 2012 Water Utilities Plan maintained the recommended project with the completion of a modified Phase I from the Kaw WTP to North 3rd Street in 2013 – 2014 to provide a redundant water supply connection to North Lawrence. The Plan recommended the completion of Phase II in 2019, and Phase III by 2025 to address capacity requirements in Southeast Lawrence. Phase I Map attached.

 

Project Status

On January 7, 2014, the City Commission awarded the construction contract to Garney Companies, Inc. and authorized the execution of Supplemental Agreement No.2 with Burns & McDonnell for Construction Phase Engineering Services.

 

As originally negotiated, Supplemental Agreement No.2 for Construction Phase Services with Burns & McDonnell anticipated providing part-time construction observation for construction duration of 240 calendar days. Garney Construction was provided Notice to Proceed as of January 29, 2014 setting Final Completion of the project on September 26, 2014.

 

On September 8, 2014, Garney was notified of the pending assessment of liquidated damages at a rate of $1,000.00/day due to the late completion of the project. Pending any approved claim for additional contract times, the assessment of these damages will offset the additional Construction Phase Engineering Services associated with the extended construction period.

 

On September 23, 2014, the City Commission authorized the execution of Supplemental Agreement No.3 with Burns & McDonnell in the amount of $40,000.00 for continued Construction Phase Engineering Services based on Garney’s updated construction schedule and proposed completion in mid-October.

 

Since the September 23, 2014 City Commission action, Garney has completed the installation of the transmission main piping; successfully pressure tested the pipe, which included locating a leak on a fitting and subsequent reconstruction of the section of pipe and fitting; and disinfected the transmission main.

 

As of January 9, 2015, successful sample collection and bacteriological testing of the transmission main was completed, the final connection to the distribution system at N. 3rd Street in North Lawrence made, and the transmission main was placed into service. The project is substantially complete per the terms of the contract.

 

Remaining cleanup and immediate site restoration activities will be ongoing into February, with some seasonally dependent items being delayed until spring.

 

As of the end of the year, the additional fee associated with Supplemental Agreement No.3, which was based on the proposed construction completion in October, has been expended. Staff has negotiated Supplemental Agreement No.4 with Burns & McDonnell in the amount of $45,000.00 to provide additional Construction Phase Services for the completion of the project. These services include continued part-time construction observation through site restoration and final completion inspection; compilation and submittal of as-built drawings; and anticipated effort associated with the evaluation of claims by Garney related to extra work and contract time.

 

Project Funding

The construction is funded from the Department of Utilities 2013 Capital Improvements and Rate Program Bonded Construction Fund Resolution 7019.

 

Action

Authorize the City Manager to execute Supplemental Agreement No.4 to the existing Engineering Services Agreement with Burns & McDonnell in the amount of $45,000.00 for continued construction phase engineering services in conjunction with project UT0701DS Kaw Water Treatment Plant Transmission Main Phase I.
