Statement of Issue: The original contract with the County's sewer design consultant Tetra
Tech, Inc. included final design and specifications for the Wastewater Treatment Plant
(WWTP) and pressurized sewer collection system for the Core Area (Phase I). Supplement #6
adds scope and budget to complete the final plans and specifications for the WWTP elements
of the project.
Analysis/Strategic Goals/Pro's a Con's: This Supplement will complete the Plans and
Specifications needed to go to bid advertisement this fall for the WWTP elements of the Port
Hadlock Wastewater Project. The following Scope of Work (SOW) has been added to the
original contract as described in Exhibit A-1: addition of a building over the WWTP; addition
of an administrative and laboratory building; addition of odor control; addition of biosolids
thickening equipment; changes to WWTP site layout to incorporate additions. This SOW was
not included in the original contract due to budget limitations; however, the current funding
package will allow these elements to be added at this time rather than being deferred to a
later date. This Supplement also includes bidding assistance for the WWTP and construction
assistance for the Phase 1 Site Work contract which is occurring this summer/fall.
Fiscal Impact/Cost Benefit Analysis: The additional budget for this supplement is $478,762 as
