Vendor: CDM Smith Michigan, Inc.
MOTION
Upon recommendation of Navid Mehram, Chief Operating Officer - Wastewater Operating Services, the Board of Directors (Board) of the Great Lakes Water Authority (GLWA), authorizes the Chief Executive Officer (CEO) to enter into Contract No. 1903601, Proposed Amendment No. 5, “Yard Piping Engineering Services”, with CDM Smith Michigan, Inc., at an increased cost of $1,332,739.08 for a total cost not to exceed $4,945,537.90 and an increased duration of 442 days for a total duration of 1,692 days; and authorizes the CEO to take such other action as may be necessary to accomplish the intent of this vote.
BACKGROUND
GLWA awarded Contract No.1903601 “Yard Piping Engineering Services” to CDM Smith Michigan, Inc. (Engineer), with a start work date of December 28, 2020. The contract is mainly divided into four (4) major phases (study, preliminary design, final design, and construction). Several amendments have been issued to this project. This was anticipated based on the contracting model for this project.
This contract now has 21 separate improvements and one (1) program. Seventeen improvements are at 100% design with bids received. However, through development of the 17 improvements, four (4) new improvements have been identified and require design.
Also, the design team identified a needed program to assess the large diameter Screened Final Effluent (SFE) loop gate valves that are needed to be operational for two (2) of the improvement projects. Furthermore, the valve operations will be a critical need for the upcoming SFE pump station replacement project.
JUSTIFICATION
There are 10 improvements authorized in the Yard Piping CMAR contract to move into construction, four (4) design projects that have come out of the completion of the other improvements, and one (1) program identified so far to move to construction. This amendment authorizes engineering services to support the construction improvements, complete the design needed, and support the SFE gate valve assessment program until August 2025.
The costs of the construction assistance phase were established based on negotiation with GLWA as hourly, not to exceed in preparation for three (3) years of construction at the site. This proposed amendment request for funding to support continued service from May 2024 to August 2025, and add design effort for four (4) new improvements.
