From an issue of The Carpenter,
These members do all of the preliminary work for prospective construction sites... They do all test borings, shotdrilling, soil samples and monitoring water tables at the site. They provide valuable information to everyone connected to the future worksite.Greg Williams, a 2 and a half-year member and Cyril Farley, an 8-month member, were working under the Manhattan Bridge. They were drilling at a proposed shaft site for a new water tunnel (there are currently 2 in New York) to meet the City’s water demand. The members were drilling 700 feet deep into the earth for the NY DEP. The machine drills into the earth and then lifts a cylinder core of the earth. Williams said, “the job will take round 3 weeks long… I like what I do, but it can be rough in the winter…outside in the cold.”
