Why was this Change necessary:
RFP 22) During construction it was determined that the design required the incorrect conduit bodies.This scope includes the replacement of conduit bodies installed on the pumps to match in-kind
throughout.
RFP 28) After construction started it was identified that the design for the generator control wiring was incomplete.Additional conduit and conductors were necessary to provide a complete
system.This scope includes installation of additional conduit and conductors necessary to complete the generator installation.
RFP 31) After construction it was determined that some additional scope items were needed.This scope of work includes repairs to existing pavement,painting the pumps to match the piping system,
and modifications to the cage ladder penetration through the ceiling that leads to the mezzanine.
RFP 32) After construction it was determined that some additional scope items were needed to keep the plant operating during construction.This scope of work includes installation of two(2)
foundations and associated drain lines to accommodate future sample stations and relocating the post injection LAS and chlorine points for Plant 1 treatment train.The relocation of LAS and
chlorine injection points were requested to allow operations to divert Plant 1 flow to nearby junction box that feeds to Clearwell 2 which will bypass Clearwell I while providing adequate post
injection whilst ensuring optimum water quality.
RFP 33) After construction it was determined that some additional scope items were needed to keep the plant operating during construction.This scope of work is related to Cost Proposal No.32 and
includes the installation of two(2)sample stations,which includes pumps,analyzers,and all electrical work required to provide a functioning system.The new sample stations will assist the
plant operations with maintaining adequate injection ratios and ensuring optimum water quality during CW 1 rehabilitation and after the decommissioning of HS#1.
RFP 34) This scope of work accounts for the project delay resulting from the Clearwell 1 rehabilitation work being postponed,allowing for the High Service#2 pumps to be rehabilitated and put back
in operation prior to the High Service#1 pumps being decommissioned.By doing this it ensured the plant was running at full pumping capacity throughout construction.
The compensation agreed upon in this Change Order is full,complete and final payment for all costs the Contractor may incur as a result of or relating to this change whether said costs are known,
unknown,foreseen or unforseen at this time,including without limitation,any cost for delay,extended overhead,ripple or impact cost,or any other effect on changed or unchanged work as a result
of this Change Order.
