SR 48 Signal Rebuilds – Traffic Signal Design

The City of Centerville is soliciting an engineering firm to prepare full construction‑ready plans, traffic‑count analyses, and signal‑timing designs for the reconstruction of three (with a possible fourth) traffic signals on State Route 48. The project requires civil, electrical, and communications engineering, right‑of‑way documentation, and coordination with existing signal hardware, adhering to ODOT, ADA, and PROWAG standards. The design effort must be completed by early April 2027, with the contract awarded in November 2026. • Design and engineering of three (potentially four) SR 48 traffic signal rebuilds, including detailed plans, specifications, and timing studies. • Preparation of right‑of‑way sheets and record plats for property acquisition and utility coordination. • Integration of existing equipment (Wavetronix stop‑bar radar, Siemens controllers, fiber‑optic network) and compliance with ODOT, ADA, and PROWAG standards. • Deliverables due by April 2 2027; contract award expected November 2 2026; construction cost estimate $600 K per signal (~$1.8 M total). • Expected design‑service fee roughly 5‑10% of construction cost, yielding a potential earnings range of $150 K‑$300 K.
