The Erie County Department of Public Works (ECDPW) retained T.Y. Lin International (TYLI) to design and provide construction inspection for the full reconstruction of 2.0 miles of Lake Avenue (Erie County Route 200) in the Town of Orchard Park, New York. The roadway was last reconstructed in the early 1970s and was experiencing severe pavement deterioration due to poor subgrade drainage due to the slag that been placed as subbase.
- During the construction phase, TYLI worked with ECDPW and the prime contractor to ensure that roadway construction met plans and specifications requirements.
- TYLI’s comprehensive documentation of all as-built revisions and instances of extra work helped to minimize the duration of the project close-out process.
- The project successfully met the challenges of a very compressed design schedule caused by a late spring letting date and the substantial early winter snowfall that delayed the topographic survey of the roadway.
- TYLI’s use of geogrid subbase reinforcement reduced the excavation, subbase, and asphalt pavement required, enabling ECDPW to stretch limited funding to cover reconstruction of the entire two-mile length of the project without compromising the project integrity of the reconstruction.
- Substantial time savings were realized by the reduction in excavation depth. The heavily compacted slag subbase had self-cemented and proved quite challenging to remove.
- TYLI implemented a road diet, where the section width of the two-lane roadway section was reduced from 40 feet to ECDPW’s newly required 30-foot standard section for urban minor arterial roadways.
