The drill machine shall be capable of performing auger borings to depths of 75 to 150 feet in unconsolidated formations with up to 12 inch O. D. conventional flight augers hollow stem augers with 3-1/4 inch, 3-3/4 inch and 4-1/4 inch I. D. with maxium 8 inch O. D. Angle hole drilling is required in certain instances to optimize the amount and type of geological information obtained from a borehole (i. e. in those areas dominated by on non vertical boreholes) is required to provide unique solutions to allow delineation of the true orientation of subsurface geologic structure. The drill shall be capable of handling ''NW'' size drill rods in a coring or rotary drilling application to 500 feet and also be capable of coring with ''PQ'' tools to a depth of 200 feet. The drill unit shall be self contained with skidding capabilities that permit access into difficult off-road sites. See Note 22. (0045)
