Tectonic worked with the Dormitory Authority of the State of New York to provide construction phase engineering and environmental services at the City University of New York Lehman College Science Center for waste characterization sampling and testing of on-site soils and real time air monitoring of particulates and volatile organic compounds (VOC) during the earthwork and excavation phase of construction of the building.
Tectonic performed the following services on site:
- Waste characterization sampling of the existing on-site soils and provided analytical testing of the samples. Sampling indicated that the fill was primarily cinders and ash with high concentrations of metals and semi-volatile organic compounds.
- Preparation of a Community Air Monitoring Plan (CAMP) for the project construction phase in accordance with New York State Department of Environmental Conservation (NYCDEC) guidance and implemented the plan during the construction of the new building.
- Positioning air monitoring stations, equipped with MiniDate Ram 1000 and a MiniRae 2000 for the particulate and VOC monitoring respectively, at upwind and downwind points near the perimeter of the site,
- Checking air monitoring stations and making field observations throughout the day to ensure air quality levels were not approaching or exceeding the limits set forth in the CAMP for the project.
- Notifying the contractor of elevated readings so that dust suppression measures would be implemented until the elevated readings subside.
- Preparation of weekly field reports containing a summary of the site activities, tabulated summary of the monitoring data for the week (i.e. exceedances, peak and average readings, weather conditions, and monitoring duration), the air monitoring raw data, and any pertinent site photographs.
