Recommendation
STAFF RECOMMENDATION:
Approve the Resolution to amend the agreement
Body
SUMMARY/KEY POINTS
• Council approval is needed to amend existing Professional Services Agreements.
• Baseline Engineering has completed contingency work facilitating progression of the project to the bidding phase.
• This amendment is needed for design support, utility coordination and construction management assistance which is imperative to successful project delivery with minimal disruption.
BACKGROUND OF SUBJECT MATTER:
This Fourth Amendment includes additional funding for items that were recently completed for the South Roundabout project design phase as well as compensation for upcoming activities anticipated to be necessary during project construction. This will include:
1) Coordination to relocate utilities including Lumen fiber optic lines.
2) Plan/profile display and permit submission for existing gas lines in the corridor.
3) As needed, construction management assistance.
4) Delivery of post-construction As-built Drawings.
Project History:
At the Sept. 8, 2020 Board of Trustees Meeting, Economic Development staff and Baseline Engineering Corporation presented its Peel Analysis, conceptual design alternatives and cost estimates; and the Board supported the Peanut (Double) Roundabout design concept for the South Gateway; and a Traditional Roundabout concept for the North Gateway.
At the March 23, 2021 Board Meeting, the Board authorized the award of a Professional Services Agreement in the amount of $448,449 and a contingency of $56,051 to Baseline Engineering Corporation to design the South (Double) Roundabout and North (Traditional) Roundabout Gateways and provide Preliminary Engineering, Final Engineering construction documents, and provide Bidding Support Services.
In April 2021, Baseline Engineering started design activities on both Gateways with the North Gateway design as the higher priority. Design plans for the North Gateway were progressed to 90% completion in late September 2021.
In early 2022, staff designated the East County Line Road Corridor Improvement projects (ECLRCI) that extends between Cheesman Street to Austin Avenue as a higher priority for design and construction; and therefore, design schedules on the North and South Gateways were extended to ensure timely design integration with the ECLRCI projects. See the attached Location Map.
In July 2022, Baseline Engineering progressed the South Gateway preliminary design for the Double Roundabout to 75% complete. In November 2022, staff determined that additional traffic analysis and modeling was needed to incorporate updated current and future 2045 vehicle counts and peak-hour vehicle volumes at Erie Parkway and Austin Avenue intersections, and school afternoon peak-hour vehicle volumes. The traffic analysis and modeling were used to simulate traffic operations, pedestrian demand, and impacts on each intersection to optimize the South Gateway design. In May 2023, the traffic analysis and modeling results supported a recommendation to change the design to a Traditional Roundabout that would better manage traffic flow through the five-leg intersection at Austin Avenue.
In June 2023, Town Council authorized a Third Amendment to redesign the South Gateway from a Double Roundabout to a traditional roundabout. Detailed analysis showed that changing the design would enable the affected intersections to perform at similar or superior levels of service (time delays), and vehicle queue lengths compared to the double roundabout configuration.
