Blazosky Associates, Inc. (BAI) provided geotechnical consulting services for the development of a leachate treatment facility at a major Eastern Pennsylvania landfill. BAI's project responsibilities included the development and implementation of a subsurface exploration plan, development of geotechnical engineering analyses and foundation design recommendations, and monitoring of foundation construction activities. The facility consists of a 4,600 square feet leachate treatment building, and a 30-foot high, dual-contained post treatment storage tank.
The exploration program included the drilling of test borings, advanced by means of a split spoon sampler. BAI provided field monitoring services throughout the exploration process, and sampled, documented, categorized and encountered materials and conditions. BAI also developed and implemented a laboratory testing program for the soil samples.
BAI performed geotechnical analyses and prepared a geotechnical investigation report. This report addressed bearing capacity, anticipated settlement, and slope stability of the site soils, with regard to the proposed structures. Slope stability was a concern for the facility because a portion of the leachate treatment building would surcharge a relatively steep fill embankment. BAI provided specific guidance regarding maximum allowable bearing pressures for the footings and concrete slabs at the facility, as well as minimum setbacks of the footings away from the slope. In addition, the report included recommendations regarding the construction process .
BAI also provided construction monitoring services for the project. These services included oversight of excavation and fill placement activities, fill compaction testing and footing construction monitoring.
BAI’s involvement with the geotechnical aspects of this project enabled the timely, successful construction of a sound facility. This project is an excellent example of our ability to provide quality geotechnical consulting services throughout a multi-phase project.
