Wastewater Department
Pump Station Upgrades Design Services — Phase {J — 30% Design
To approve the second phase of the Design Phase Services to Woodard &
Curran of Portland, ME in amount not to exceed $554,853. Funding will be
through: Department: 169 - Wastewater; Fund: Wastewater; Activity: Pump
Station Upgrades.
Pump Station Upgrades — 30% Design Phase-Scape of Work and Fee
There are thirteen (13) pump stations, one of which only operates when needed
during combined sewer overflow events maintained by the Wastewater
Department. Most of these pump stations are the original pump station
structures that have aged considerably. Woodard & Curran was hired to
perform a preliminary evaluation and provide recommendations of the
upgrades needed at all 13 pump stations, They have completed this evaluation
and are now ready to proceed to the 30% design phase of this project.
During the 30% design phase, W&C will further evaluate some of the possible
modifications that occur at various pump stations. They will hire sub-
consultants to perform survey and geotechnical studies, A considerable portion
of their fee is for the sub-consultants, amounting to $201,900, This fee may be
less if it is determined during the 30% design phase that some geotechnical or
survey work can be reduced.
Their scope also includes preparation of preliminary cost estimates and
preparation of a Design Basis report that will summarize various options such
that the City can decide the optimal way to proceed going forward. At the
conclusion of the 30% phase it will be made clear to W&C on how to proceed
forward into the final design phase.
We recommend continuing this work with W&C into the 30% and final design
phases. They have performed competently during the study phase and will
continue to do so. Their costs for the 30% design phase were found to be
reasonable for the scope of work involved. This project is eligible for a 20%
State Aid Grant from the New Hampshire Department of Environmental
Services.
