Summary
This Change Order provides for the full-time construction management and inspection needed for the improvements to the W.E. Dunn Offsite Reclaim Water Pump Station. The scope of the services will include managing all construction related meetings (attending and moderate); manage the review/approval of all shop drawings, requests for information, and additional work authorizations submitted by the contractor; provide construction observation and inspection for all construction activities; provide daily reports; review all invoices and schedules from the contractor throughout the construction and completion of these improvements.
This construction project is large scale and requires full-time construction services to monitor and manage all activities.

Work will also include piping, valving and metering to allow surplus reclaim water to be pumped from the County’s Interconnect PS located in Oldsmar back to the Dunn plant’s reclaim pond.

Background Information:
This contract was awarded by the Board of County Commissioners on June 2, 2020, in the amount of $752,557.11.
The Dunn Offsite Reclaim Water Pump Station was originally constructed in 1987. In 1998, modifications were made to add four strainers on the discharge side of the pumps. Components including the vertical turbine pumps, electrical gear and strainers have reached the end of their useful service life. The pump station provides reclaimed water to the north county’s public access reuse system as well as providing critical in-plant water needed to support various treatment processes. The pumps are not able to operate in the preferred operating range and therefore are not able to provide the design flow rates needed. Recently, the pumps have required significant maintenance and have been rebuilt multiple times.
