RE: Proposed Amendment No. 6
Contract No. 1903601
Yard Piping Engineering Services
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. 6, “Yard Piping Engineering Services” with CDM, at an increased cost of $619,202.83 for a total cost not to exceed $5,564,740.73 and an increased duration of 265 days for a total duration of 1,957 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). The Contract is divided into four major phases: study, preliminary design, final design, and construction.
To date, five amendments have been issued. This Contract now has nineteen (19) separate improvements* for design/construction and one program for secondary final effluent (SFE) valve exercising which has been incorporated in previous amendments to this Contract.
Amendment No. 6 seeks to add $619,202.83 for Task 2 project management, Task 8 resident project representation (RPR), and task 9 construction assistance for administrative and field engineering services during construction and extends the Contract time by a total of 265 days.
*This is a correction to scribal error in prior board letters which stated there were 21 improvements.
JUSTIFICATION
This amendment supports the construction assistance phase needed for the improvements outlined in the Change Order 6 of the CMAR contract of the project. The costs were negotiated in detail with GLWA’s Lifecycle Project Manager as hourly, not to exceed, in preparation for two (2) years of construction assistance services at the Water Resource Recovery Facility for 15 of the 19 improvements. Four (4) of the design improvements are still currently under design and a price for construction assistance will be determined as those improvements reach 100% design, and a future amendment may be brought to the board for approval. The construction assistance services included within this amendment will be provided for The Christman Company construction related services for the 15 improvement projects which are at final design stage
