TO: Erin Rinehart, City Manager
FROM: Jonathan Wheat, Jr., P.E., Director of Engineering

Title
Consider A Resolution Authorizing The City Manager To Negotiate And Execute A Contract Amendment With Bridgefarmer & Associates, Inc. For Signal Design Services To Establish A Quiet Zone In Downtown Carrollton, In An Amount Not To Exceed $40,000.00, For A Revised Total Amount Not To Exceed $615,000.00.
Body
BACKGROUND:
In August of 2024, the City of Carrollton contracted Bridgefarmer & Associates, Inc. to analyze and design a quiet zone in the Downtown area for $575,000.00. The project is currently at 30% designed. Quiet Zone 3 includes three (3) crossing locations along the BNSF railway and seven (7) crossing locations along the DGNO railway. Expenses for a signal design at each crossing were not included in the original estimate, because it was unknown if the railway entities would be completing the signal design in-house or if our consultants would be completing the design work. BNSF chose to have the city's consultant complete the design for the three (3) locations that involve their railway. DGNO requires a separate Engineering Cost Reimbursement Agreement to provide signal design services for their seven (7) crossings.
FINANCIAL IMPLICATIONS:
Bridgefarmer & Associates, Inc. has submitted a proposal to the City of Carrollton to address the signal design services for the three (3) BNSF crossing locations in an amount not to exceed $40,000.00.
Separately, staff is submitting an Engineering Cost Reimbursement Agreement for the signal design of the seven (7) DGNO crossing locations within Quiet Zone 3 in an amount not to exceed $210,463.00. The necessary funding is available in Streets fund.
Design costs are offset by expected savings in construction costs. No signal construction is required at the DGNO crossing of Broadway and the Private Drive south of Crosby Road....
