This project involved geotechnical analysis and laboratory material testing for the construction of a pumping station at the Little Patuxent Water Reclamation Plant and about 11,800 linear feet of 16-inch HDPE force main.  Investigation included 65 roadway and/or soil borings.  Extensive laboratory testing was also conducted to determine the classification and suitability for use as backfill for the soils along the force main alignment.  A report was prepared with our findings and recommendations for the force main installation, pipe bedding, thrust restraint, tunneling at major roadway and railroad crossings, and earthwork.

Lab Testing:

• Classification
• Compaction

• Tunnel Crossings.
• Excavation support along heavily trafficked roadways.
