Advantage Engineers performed engineering services for a proposed monopole telecommunications tower located in Conshohocken, Pennsylvania. The 150’ tower, proposed by a leading wireless carrier, was within an irregularly shaped 2,500 square foot area adjacent to an existing scrap metal storage building. The tower plan included nine (9) panel antennas along with construction of a 10’ x 20’ concrete pad for associated telecommunications equipment.
In order to identify recognized environmental conditions (RECs) in connection with the subject property, Advantage Engineers conducted a Phase I Environmental Site Assessment. A detailed assessment revealed two areas in need of further investigation.
The scope of the investigation included:
- Visual inspection of the subject property and surrounding properties
- Review of federal and state database information
This Phase I ESA included the following activities:
- Review of selected historical aerial photograph
- Research and review of available background information regarding the subject property in order to identify areas and/or items of potential concern relative to contamination or storage of hazardous waste
- Contact with federal, state and local agencies regarding the availability of files for the subject site
- Perform visual reconnaissance to identify evidence of RECs
- Interview with the property owner
Advantage Engineers completed a National Environmental Policy Act (NEPA) screen for the proposed site. Site reconnaissance, field delineations, and public files were reviewed in order to determine if the proposed site may have an environmental impact such as endangered species, critical habitats, wetlands, floodplains, wilderness preserves, historic/archeological resources, and Indian Religious Resources. Regulatory agencies were consulted as part of the screening process.
Advantage Engineers conducted a subsurface field investigation and laboratory testing program at the proposed site. A series of standard SPT earth borings were conducted. All sample soils were visually reviewed and classified. Upon completion of laboratory testing and analyses, our staff prepared a geotechnical data summary report. It was determined that materials found within the fill layer were not suitable for a shallow “pad & pier” foundation. In turn, enhanced foundation design recommendations were provided.
