Background:
CC-5049-23/TAD provides the removal and replacement of the underground post-chlorine chemical injection assembly located on the suction line ahead of high service pumps (HSPs) at the Country Club Water Treatment Plant (CCWTP).
Change Order #2 provides for a change in design needed due to the inability of the neighboring utilities, through existing interconnects, to adequately provide water and system pressure allowing for a two-day shutdown to install the assembly. During project development, staff reviewed with interconnected utilities the possibility of supporting the Country Club water distribution system while the plant itself was offline to make repairs to the aging plant intake manifold which was originally designed and constructed without a bypass. However, following the notice to proceed, Sanford and Longwood identified issues preventing adequate water supply at the time of shutdown. Thus, additional live testing was conducted. The testing demonstrated the Country Club Water Treatment Plant could not be taken offline, as planned, without significant service disruption. The design change includes a temporary and permanent bypass constructed with the above-ground chemical injection assembly, providing mechanisms for future R&R and maintenance without service interruption or reliance on interconnected utilities. Additionally, this Change Order will also extend the contract by an additional 80 days to accommodate the long lead time for the additional material order (24-inch gate valve).
The following is a summary of the cost of the Agreement:
Original Agreement Sum: $264,327.00
Change Order #1: Time Only (180 days)
Change Order #2: $263,440.99
Revised Agreement Total: $527,767.99
This is a budgeted project, and funds are available in Country Club WTP R&R (Acct #00178304.560650)
