Title
Consider A Resolution Authorizing The City Manager To Negotiate And Execute Contract Amendment No. 1 With Transystems Corporation DBA Transystems Corporation Consultants For Additional Professional Engineering Design Services Related To The Furneaux Creek Hike And Bike Trail Project In The Amount Of $56,407.00, Increasing The Total Contract To An Amount Not To Exceed $213,111.00.
Body
BACKGROUND:
On October 18, 2016 City Council approved a contract in the amount of $156,704 for the design to extend the Blue Trail along Furneaux Creek from Old Denton Road to the DART Trinity Mills Station.
Contract amendment No. 1 is needed to fund the costs for additional design work, survey work, and parcel documents in order to avoid flooding issues, as well as the costs for trail re-alignment design work and survey work required to avoid property acquisition at 1448 and 1458 MacArthur Drive.
The initial trail alignment was located along the toe of the slope within the channel between Trinity Mills and Dickerson Parkway. Maintenance staff began having issues with the existing trail at Old Denton Road due to periodic flooding. As a result, the trail will be re-aligned to the top of the slope to avoid continued maintenance due to flooding. Also, while reviewing the initial alignment, it was determined that a trail access will be added at Dickerson Parkway and the trail is to be continued further south to the bike racks at Trinity Mills Station. Additional design, survey, and parcel documents are required to address these elements.
The current alignment requires a public use easement along the western side of 1448 MacArthur Drive and additional right-of-way along the frontage of 1458 MacArthur Drive. City Council was previously briefed on the cost to acquire the needed easement and determined that the cost was excessive. Since the property acquisition cost could far exceed the redesign cost, the best course of action is to seek an alternate route. The trail is to be re-aligned to continue along Furneaux Creek to the PGBT frontage road, then follow Trinity Mills East to MacArthur Drive to bypass the properties at 1448 and 1458 MacArthur Drive. This route requires additional design and survey work.
FINANCIAL IMPLICATIONS:
Transystems Corporation Consultants has submitted a proposal to the City to perform the additional engineering design services in an amount not to exceed $56,407.00. Funding is available from Parks Consolidated General Obligation Bond Funds.
IMPACT ON COMMUNITY SUSTAINABILITY:
This project will support the City Council’s strategic objectives and vision of building a community that families and businesses want to call home by:
• Promoting a healthy, pleasant alternative to motorized travel.
• Providing a safe and continuous connection between neighborhoods in Carrollton and DART’s Trinity Mills Station.
STAFF RECOMMENDATION/ACTION DESIRED:
Staff recommends City Council approve a resolution authorizing the City Manager to enter into contract amendment no. 1 for the additional design services for the Furneaux Creek Hike and Bike Trail project with Transystems Corporation in the amount of $56,407.00, increasing the total contract amount to an amount not to exceed $213,111.00.
