John Tallman
Project Manager, Findling, Inc.
Mr. Tallman has 16+ years of experience in Project Management. He is proficient in Microsoft Office Suite, has excellent mathematical skills and strong leadership abilities, and is a team player. He has managed several field investigation projects of varied scope and project duration. He has also managed field inspectors on construction related projects.

Mr. Tallman performed inspection of drilling operations at the site during the subsurface investigation for the proposed rehabilitation of the existing sewer. The location of the test borings was first cleared by using vacuum extraction test pitting method in the area of the test borings. The test holes were performed to locate the existing underground utilities that were not marked in the area of the proposed boring locations. The tasks included visual classification of soil samples and rock samples, locating the test borings at the appropriate locations and selecting the appropriate sampling intervals.

Mr. Tallman prepared Traffic Control Plan and coordinated with SHA to obtain the necessary permits, coordinated with property owner adjacent to MD 103, performed inspection of drilling operations including visual classification of soil samples obtained from SPT samples, obtaining appropriate samples of each stratum and recording of field activities. He also performed in-situ infiltration tests in offset boreholes at proposed SWM facilities to determine the in-situ infiltration rates of on-site soils.
