RE: Proposed Change Order No. 4
Contract No. 2004082
Rehabilitation of Woodward Sewer Systems
Vendor: Lanzo Construction Co.
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. 2004082, Proposed Change Order No. 4, “Rehabilitation of Woodward Sewer System” with Lanzo Construction Co., with no increase in cost for a total cost not to exceed $18,695,250.00 and an increased duration of 304 days for a total duration of 1,335 days; and authorizes the CEO to take such other action as may be necessary to accomplish the intent of this vote.
BACKGROUND
The Woodward Sewer System (WWSS) is a major combined sewer system aligned with Woodward Avenue starting at McNichols Road and conveys sewage through the cities of Highland Park and Detroit to the Detroit River Interceptor (DRI). In addition, one leg of the WWSS extends sewer service to the east along Chandler and Clay streets and runs north into the city of Hamtramck. This leg of the sewer, referred to as the WS-300 segment, consists of circular and egg-shaped brick sewers that are being rehabilitated by sliplining and Cured in Place Pipe (CIPP).
Change Order No. 1 extended the contract time for sliplining of the WS-300 sewer for extended material procurement time due to the pandemic and additional time for evaluation of potential substitutions.
Change Order No. 2 extended the key milestones for substantial and final completion dates by 42 days without liquidated damages. There was no change in contract value associated with this change order.
Change Order No. 3 extended the Contract time by 61 days with liquidated damages. There was no change in contract value associated with this change order.
JUSTIFICATION
This request is to extend the contract time of the project by 304 days with liquidated damages from August 1, 2024, to June 1, 2025. The contract time extension keeps the contract current past the final completion date, allowing for performance of the contract beyond final completion without interruption, if necessary, with GLWA reserving the right to assess liquidated damages for time beyond the key milestone of final completion which was June 1, 2024.
