Woodard Curran Scope of Work and Fee.
The purpose of the potable water booster station is to increase the pressure and
flow rate of potable water entering the plant. It was originally installed in 1988
as part of the secondary upgrades project and consists of 2 underground vaults,
one for the water meter and backflow preventer valves and the other consisting
of pumps on skid. The water system vaults are at a low point in the water
distribution system and are subject to grit accumulation which has caused
issues with the back flow preventer valves closing properly.
A request for qualifications (RFQ) was sent to 6 consultants. Two of the
consultants expressed an interest in the project and were interviewed. A
comunittee picked Woodard and Curran as the consultant for this project, based
on their better experience and familiarity with the NWTF.
The design project will have various phases beginning with the request to fund
a preliminary evaluation and study of the booster station. Following the study
and evaluation phase the consultant will have determined the optimal method
for upgrading the water booster system and will have a better estimate on costs
going forward. A separate contract for design phase services will be
developed following the study-evaluation phase.
Woodard and Curran has an accelerated schedule for completing the study-
evaluation phase in one month. They have completed numerous water
upgrades projects at wastewater treatment plants and are well qualified for this
work.
