CITY COMMISSION AGENDA ITEM

Department:

Utilities

Commission Meeting Date:  July 17, 2018

Staff Contact:

Chris Rice, Project Engineer

Action Requested:

Authorize the City Manager to execute Engineering Service Agreements with George Butler Associates Inc (GBA) and Professional Engineering Consultants (PEC) for a total of five watermain replacement projects.

Executive Summary:

Department of Utilities staff continuously evaluates the condition of the water distribution system based on the occurrence of main breaks, pipe material and age, capacity, and fire protection needs. Based on these criteria, watermains are targeted for replacement over a three year period. A total of $11.54 million dollars is allocated within the Capital Improvement Plan for Watermain Replacement/Relocation in years 2018, 2019, and 2020 (CIP# UT9902). A total of five projects have been identified for design and construction through 2019. These projects are listed and described below:

		Existing Pipe Data and Project Comments
No.	Project Name	Age (Years)	Diameter (Inches)	Length (Feet)	Recorded Breaks (#)
1	9th St – Arkansas St to Emery St | 1527 W 9th Street	89	4” & 6”	570’	9
		Comments: extensive traffic control provisions (9^th St), possibly 2 taps of 16” concrete watermain, 2 distinct project locations (multiple mobilizations), relatively short total project length, dense service connections, easement acquisition.
2	Lawrence Ave – 8th St to Bob Billings Pkwy | 9th St – Lawrence Ave to Schwartz Rd	64	8”	5,900’	19
		Comments: traffic control and coordination with neighboring schools.
3	Camelback Dr – Tam O’Shanter Dr to Quail Creek Dr	50	6”	1,550’	7
		Comments: relatively short total project length.
4	Louisiana St – 19th St to 20th St and 21st St to 23rd St	28	8” & 12”	2,100’	8
		Comments: extensive traffic control provisions (Louisiana St), coordination with neighboring schools.
5	14th St – Massachusetts St to Delaware St | New Hampshire St – 14th St to 13th St | New Jersey St – 14th St to 15th St	118	4” & 6”	3,400’	5
		Comments: eliminate existing dead end watermain, traffic control and coordination with neighboring school.

Additional waterlines have been identified for replacement in late 2019 and early 2020. The priority of these projects may shift based on changing system conditions or emerging problem areas. Additional Engineering Service Agreements (ESAs) will be provided to the City Commission in early-2019 for these upcoming projects.

GBA and PEC were selected via a competitive Request for Proposal process initiated in March 2018. The City Commission authorized the use of these consultants for the project at its May 15, 2018. A program kickoff meeting was held on June 6, 2018 with Utilities Department staff and representatives from both consulting firms. GBA was selected to perform design engineering services for projects 1 and 2. PEC was selected to perform design engineering services for projects 3, 4, and 5.

Individual Engineering Services Agreements have been prepared for each of the five referenced projects. The scopes of each project include topographic survey, replacement waterline design, geotechnical investigations, traffic control planning/design, and construction phase services.

The scopes and fees provided for each of the five projects have been reviewed by department staff and found to be appropriate given the scope and anticipated construction cost of each project. A summary of each is included below:

No.	Project Name	Designer	Construction Cost Estimate	Engineering Fee*
1	9th St – Arkansas St to Emery St | 1527 W 9th Street	GBA	$300,000	$77,509
2	Lawrence Avenue – 8th St to Bob Billings Pkwy | 9th St – Lawrence Avenue to Schwartz Rd	GBA	$1,200,000	$162,177
3	Camelback Dr – Tam O’Shanter Dr to Quail Creek Dr	PEC	$297,600	$55,779
4	Louisiana St – 19th St to 20th St and 21st St to 23rd St	PEC	$517,200	$86,393
5	14th St – Massachusetts St to Delaware St | New Hampshire St – 14th St to 13th St | New Jersey St – 14th St to 15th St	PEC	$652,800	$86,745
	TOTAL		$2,967,600	$468,603
*Includes: Basic Services + Non-Basic Services + Construction Phase Services
