Traffic Analysis And Environmental Investigation- Binghamton University Academic Building

City of Binghamton, New York

This project involved the construction of an approximately 60,000 square foot, multi-story academic building on a two (2) acre site in the City of Binghamton.

Shumaker Consulting Engineering & Land Surveying, P.C.(SCE) was responsible for performing accident analysis; capacity analysis; parking analysis; level of service; geometric studies and cost estimating associated with access to the site impacts to traffic and parking within the project area.

SCE evaluated morning and afternoon peak traffic periods at fourteen (14) intersections including five (5) signalized intersections. SCE utilized CORSIM and SYNCRO software to model traffic in the project study area. Utilizing the Regional model, expected routes were forecasted for the major entryways into the urban core of the City of Binghamton.

Findings from this traffic study were subsequently incorporated into the site design for the new academic building, under separate contract.

Phase I/II Environmental Site Assessment tasks included performing a physical inspection of the property; visual inspection of the surrounding area; personnel interviews; review of requisite environmental permits and records; review of useful and “reasonably ascertainable” historic sources pertaining to former uses of the site and adjacent sites.

Vapor Instrusion Study

Village of Endicott, County of Broome, New York

Shumaker Consulting, Engineering & Land Surveying, P.C.(SCE) conducted vapor intrusion surveys at 25+ residences and businesses in the Village of Endicott. SCE conducted interviews with the owner and/or tenant(s) of each subject property.

The New York State Department of Health Indoor Air Quality Questionnaire and Building Inventory was completed to document the interview and building survey. In support of the building inventory, SCE performed a survey of potential sources of volatile compounds within the sampling areas. The inventory included: type and quantity of each material present, list of volatile ingredients present, assessment of the material’s container, and a reading from a photoionization detector to determine if volatiles were being released.

Upon completion of the interview, questionnaire and survey process, SCE collected air samples to represent the basement sub-slab air, basement ambient air, first-floor ambient air, and outside ambient air. The sub-slab samples were obtained by coring through the basement slab, installing a sample collection hose, and sealing the area around the hose with beeswax.

Ambient air samples were collected within the breathing zone, four to five feet above the floor or ground. All samples were 24-hour collections using one-liter Summa canisters and precalibrated flow controllers. Each sample was recorded in a Chain-of-Custody and the configuration was photographed for documentation.
