A. Morton Thomas & Associates, Inc. Subsurface Utility Engineering Division will be on the Germantown Campus from Tuesday, March 16 through Friday, March 19 locating utilities for the Bioscience Education Center project.
The American Society of Civil Engineers has implemented a standard of subsurface utility engineering manual entitled CI/ASCE 38-02. Utilizing this criteria, AMT will collect and depict reliable data for existing utilities that is critical for making informed decisions and supporting risk management protocol regarding the impact of these utilities on this project.
They will use non destructive vacuum excavation technology to visually locate underground utilities. This versatile "daylighting" method is safer, faster, less labor intensive, and results in smaller holes without damaging the utilities. A high pressure stream of air breaks up the ground and a high air flow vacuum simultaneously suctions up the debris, dirt, rock, etc. and deposits the spoils in a holding tank. Once the engineers measure the size and the depth of the utilities the spoils material will be used to back fill the holes. The restoration process will leave the 8"-12" square holes in the same condition as found. Holes in the asphalt will be patched with cold patch material.
There will be one vacuum truck and one pick-up truck, and two to three field technicians on site daily from approximately 8 a.m. to 2:30 p.m.
