The City of Tukwila has been selected to receive funding through DOE Agreement No. WQC-2023-Tukwil-00073 ("Grant Agreement") in the State Fiscal Year 2023 (SFY23) Funding Cycle. The work includes: Site 1: Tukwila International Blvd at SR 599 Oft -Ramp Install two new modular wetland units, storm conveyance pipe, and restoration ofgore area to treat stormwater runoff before it outfalls to Riverton Creek. Site 2: Interurban Ave S at 580' Ave S Install new modular wetland unit, storm conveyance pipe, and street trench restoration to treat stormwater runoff before it outfalls to the Duwamish River. This location will also be replacing existing signalized intersection loops with permanent video detection. A detailed scope follows: I. INTRODUCTION Shortly before construction began for the project it was discovered there were additional requirements for completing the work at the SR 599 Oft -Ramp due to the work being in WSDOT Limited Access Right -of - Way. The Contractor intended to start work at this site, but had to shift work to the Interurban site until the requirements of WSDOT were met. This caused a delay in the project starting and forced the project into splitting the work into two construction seasons. A complete list of items that extended the project scope and time to completion are as follows: 0 Unexpected WSDOT coordination caused scope and time increases o Structures installed within the WSDOT ROW had to be stamped by the Materials Lab, requiring additional coordination time. o The 35 working days were split between Fall 2024 and Spring 2025 creating additional time administrative items required by the Contract. o WSDOT coordination continued through the winter months to resolve their requirements for the WQ vault yet to be installed within their limited access right-of-way. o Certified payroll tracking continued through the suspension period. City of Tukwila Storrynwater Outfall Water Quality Retrofit Project Construction Management Services Page I of 7 Psoinas June 19, 2025 EXHIBIT A-5 The Contractor's vault supplier had delays in shipping the items to site. This forced the Contractor to pave on two days instead of one for the Interurban site. Increasing the amount of testing required. New crushed rock and HMA materials were submitted for the work to be completed in the spring, which required additional conformance testing. An unmarked conduit was discovered running through a section of the project. There were four non -working days associated with this discovery as the Contractor lost efficiency and was working on non-critical items during this time. Additional non -working days were granted for weather. Some work continued on these days but was inefficient. General Assumptions: There are 15 working days remaining in the Contract. Work is expected to wrap up within this time, except for punchlist items. 0 Coordination with WSDOT will continue as work progresses within their ROW. The proposed project team will include a part time Resident Engineer (10 hours a week), one full time Construction Inspector, a part time Documentation Specialist (20 hours a week), and one part time Project Engineer from Psomas's design team to review submittals and interpret Contractor inquiries, as needed. The team also includes a sub -consultant to provide services for materials testing and construction site observation to satisfy Tukwila Municipal Codes for work within certain soil classifications. • Consultant will coordinate during audits or traffic control operations related to project impacts and help the City to complete any other required correspondence with outside agencies. • Psomas design engineers will be available during construction to answer questions and review RAM's, shop drawings, and answer RFI's. • Consultant services will be performed in accordance with the WSDOT Construction Manual, Contract plans & special provisions, and City of Tukwila engineering standards. • The franchise Utilities will provide field inspection for all work surrounding the construction or relocation of their utility systems if necessary.
