Commission approves supplemental agreement for South Street railroad crossing design and inspection
Summary
The Lafayette Redevelopment Commission approved Supplemental Agreement No. 2 with Butler, Fairman & Seifert to add survey, signal redesign, irrigation design, geotechnical work and construction inspection services for the South Street Railroad Crossing project.
The Lafayette Redevelopment Commission approved Supplemental Agreement No. 2 on Sept. 25 with Butler, Fairman & Seifert (BFNS) for additional engineering and inspection services on the South Street Railroad Crossing project. BFNS representative Chris Wheatley described the supplemental work as additional survey, traffic signal redesign (switching from span-wire to mast-arm/cantilever signals), irrigation design for median landscaping, geotechnical investigations and construction inspection services.
Chris Wheatley said some existing survey information came from earlier Sycamore Parkway/Sagamore Parkway work but that recent changes at properties such as Leo’s convenience store required updated field pickup. He told the commission that switching to mast‑arm signals required additional geotechnical and design work not accounted for in the original scope. Construction inspection was the largest line item in the supplement and was presented as an hourly, not‑to‑exceed budget based on about 8% of the estimated construction cost; staff said city inspectors and shared staffing with an upcoming Ninth Street project will be used to limit costs.
Redevelopment Director Dennis Carson said the supplemental agreement totals $314,800 and will increase the contract to a new total of $770,100. Carson and BFNS emphasized the not‑to‑exceed nature of the supplement and said prior projects had used substantially less than earlier budgets for inspection.
A commissioner asked for assurance that the supplemental amount had staff and council scrutiny; Carson and Wheatley said the not‑to‑exceed budget is intended to cover anticipated services and that the actual spend may be lower depending on inspections required. The commission moved, seconded and approved Supplemental Agreement No. 2 by voice vote.
Why it matters: The supplemental agreement covers design and inspection elements that affect signal installations, landscaping irrigation, geotechnical safety for mast-arm foundations, and on‑site construction oversight. The agreement’s largest component is construction inspection, which is commensurate with the project’s complexity and the city’s requirement to document construction compliance.
