This work in partnership with industry is a continuation of cost- effective innovative, directional boring development begun in FY90 and planed to extend into FY94. Several demonstrations of the strategy of building hybrid hardware from utilities installation, geothermal, and soil mechanics technologies have been performed at Sandia National Laboratories (SNL) and at Charles Machine works (CMW) test sites as well as at a commercial refinery site. Additional tests at the SNL Directional Boring Test Range (DBTR) and a lagoon site are planned in calendar 1991. A new companion project to develop and demonstrate a hybrid capability for horizontal logging with penetrometers, specialty instruments and samplers has been taken from concept to early prototype hardware. The project goal of extending the tracking/locating capability of the shallow boring equipment to 80in. is being pursued with encouraging results at 40in. depths. Boring costs, not including tailored well completions dictated by individual site parameters, are estimated at $20 to $50 per foot. Applications continue to emerge for this work and interest continues to be expressed by DoD and EPA researchers and environmental site engineers. 12 figs.
