Description
Project: D54713 – Route 481
Location: Clay, New York
Owner: NYSDOT
Engineer: NYSDOT
Contractor: Tuscarora Construction
Manufacturer: Kistner Concrete Products Inc.
Scope: Precast concrete technology replaces the corrugated steel “multi-plate” in a search for quality and longevity.
Due to structural deficiencies, a twenty year old corrugated metal “Multi-plate” arch culvert under Route 481 in Clay, New York (Onondaga County) needed replacement. NYSDOT decided not to make the same mistake of using outdated “Multi-plate” technology twice. As a result it choose to use twin 20’-0” x 8’-0” Precast Box Culverts to replace the bridge.
Precast was a timely and long lasting solution which could easily meet emergency replacement timetable. The Contractor and state officials were extremely pleased with the speed of the project and the high quality finished product. “We were smart this time to have selected a bridge system that will be here in 100 years,” was the comment of one state official.
Kistner supplied a 352 LF twin cell 20’-0” span x 8’-0” rise Box Culvert. The total breakdown was sixty-five 5’-8” sections @ 28 ton each. Precast toe walls were also supplied for the job. AASHTO HS-25 bridge loading was required. Total production was accomplished in a 4 week period to meet the emergency replacement schedule. Installation was accomplished during a 10 day period.
Construction schedule: This project provides an example of the speed that can be achieved through the use of a Precast Box Culvert. The job went up for bid in May, and the concrete was produced in 4 weeks. The finished product was delivered in September, and Kistner completed the installation within the proposed 10 day schedule.
Cost: $200,000.00 for all precast delivered.
Structural: Precast Concrete Box Culvert System – double cell – AASHTO HS-25 load requirements.
Lesson Learned: When “life cycle costs” are taken into consideration, a precast solution is always the most cost effective choice.
