The Supplemental Agreement will increase the contract by $59,520, for a new total of $1,325,354. BACKGROUND Since September 2019, TranTech Engineering has been working on the design and construction management of the West Valley Highway project including improvement along Longacres Way. Currently, the project has funding for construction from two grant sources: Transportation Improvement Board and Sound Transit System Access Funds. The project is also on the Traffic Impact Fee list. Construction started in 2022 and was expected to be completed by the end of the year, but supply chain issues specific to signal and light poles forced a winter shutdown last fall. Work resumed by the City's contractor, Road Construction Northwest, in May of this year. DISCUSSION Once the work began again this spring, new issues arose that have added further delay to the completion of the project. The work is nearly physically complete at this time, but some items still remain incomplete such as fabrication and installation of a new mast arm at the Longacres Way/West Valley Highway intersection and getting electrical connections completed by Puget Sound Energy so that the new streetlights and RRFB on Longacres Way can be energized. Delays result in additional time and funds being required for the construction management support from TranTech. FINANCIAL IMPACT The increase in fee for the additional construction management effort totals is $59,520. Budget is available for the increase through the remaining construction contingency, which is partially reimbursable through the two grants. CM Increase Fee Fund Source $59,520 Available contingency Budgeted $465,220.61 RECOMMENDATION The Council is being asked to approve the Supplemental Agreement No. 4 to Contract No. 19-095 with TranTech Engineering in the amount of $59,520, for a total of $1,325,354 and consider this item on the Consent Agenda at the December 11, 2023 Special Meeting.
