About this file
This is an engineering estimate document for the Greater Dayton Regional Transit Authority (GDRTA) Electric Trolley Line project in Ohio. The estimate details materials and labor costs for trolley infrastructure wire installation across five fiscal years from 2026 through 2030. The project requires five primary wire and cable types: 2kV 1000 MCM Feeder Cable (11,000 linear feet), 2/0 Grooved Brass Cable (5,280 linear feet), 4/0 Cable Uninsulated (1,000 linear feet), 4/0 Insulated Cable (1,000 linear feet), and Galvanized Strand Wire (2,500 linear feet). The estimate projects unit price escalation annually to account for material cost increases over the five-year procurement period.
The cumulative engineering estimate totals $2,046,021.93 across all five years, with individual annual totals ranging from $287,115.84 in 2026 to $504,439.56 in 2030. Each annual estimate includes a 10 percent contingency allocation applied to the base material costs. The estimate reflects anticipated price increases for electrical materials, with the 2kV 1000 MCM Feeder Cable—the largest cost component—escalating from $25.45 per linear foot in 2026 to $37.26 per linear foot by 2030. This engineering estimate serves as the baseline for bid preparation and budget planning for the trolley infrastructure wire procurement project.
