The Gilcrease Turnpike Project, located in Tulsa, Oklahoma, is a multi-phase turnpike extension. Chris LaViolette worked with multiple contractors to establish protocols ensuring that work would not be impeded should environmental concerns or issues be discovered during construction. Chris sought to establish a comprehensive structure of communication with the contractors in charge of the project to set goals and expectations for the environmental team. Overall, the extension across the Arkansas River was completed with minimal environmental disturbances disrupting other aspects of the project.

The proposed high rise project started with a Phase I Environmental Site Assessment which identified multiple recognized environmental conditions on and adjacent to the site. The project then moved to a limited site assessment and sample collection on site. The samples were collected along with the installation of temporary groundwater monitoring wells. A closing conference was conducted with the client after delivery of the report showing the site was free of contaminants.

This project involved a real estate transaction for an industrial building located in northeast Oklahoma. The facility was involved in various types of manufacturing during its over 30-year existence. A Phase I Environmental Site Assessment was conducted, which identified recognized environmental conditions (RECs). A limited site assessment was then conducted on-site to determine if contaminants were present in the soil or groundwater. The investigation revealed that contaminants were present on-site. It was decided that an interior air quality and sub-slab vapor intrusion investigation would be conducted to determine if there was an an exposure pathway to future employees. After the investigation, it was shown that the slab of the facility was not allowing contaminants to penetrate into the building. The client was satisfied with the results and proceeded to pursue purchasing the facility.

This project was a two-week sampling investigation in a town developed on old mine tailings in Arizona. Stephen worked with the client and safety contractors to sample several high-use areas in the town, with the goal of quantifying the level of heavy metal contaminants in and below the topsoil. During this time, Stephen led a safety meeting that highlighted the need to work more closely with the local city government, which helped minimize delays during an emergency preparedness drill. The project ultimately led to a two-year sampling and data collection effort.
