Approval of Supplemental Agreement No. 3 with Integrity Structural Engineering, PLLC in the amount of $196,425 for Bridge Engineering On-Call Consultant Support for the Overlake Village Station and Redmond Technology Station Pedestrian Bridges
OVERVIEW STATEMENT:
recommendation
This Supplemental Agreement provides for additional bridge engineering services needed to provide continued construction support for two new pedestrian bridges in the Overlake Neighborhood. The Overlake Village Station (OVS) Pedestrian Bridge is being delivered by Sound Transit under their E360 design-build contract. The Redmond Technology Station (RTS) Pedestrian Bridge is being delivered by Microsoft under a separate design-build contract. Both bridges will be conveyed to the City after they are completed. Additional costs are funded from existing project budgets.
Additional funds are needed for the OVS Pedestrian Bridge because the construction duration is longer than originally planned and level of effort required to respond to changes and address non-conforming work is greater than anticipated.
For the RTS Pedestrian Bridge the level of the support needed during construction is greater than anticipated due to the complexity of the project, construction challenges, large number of design changes, need to address non-conforming work, and nature of the design-build process. In addition, the construction duration is longer than originally anticipated.
