The demand for new buried utilities is growing with new construction, reconstruction, and the growth of the subsurface infrastructure worldwide. As a result, contractors are busy digging and trenching to bury new pipes. Because the machinery needed for placing the new utilities underground, such as backhoe excavators, trenchers, augers, drills, and plows, don't "feel" when they are getting close to already buried object, utilities are easily damaged. Despite great efforts in locating existing utilities before a contractor is allowed to dig, accidents occur in great numbers. The core idea of the concept presented in this paper is to provide the equipment operator with his own system that alerts him of the danger rather than to depend on the hand-held approach alone. A sensing platform, operating like a subsurface "X-ray", has been attached directly to the machinery, hence providing the operator an opportunity to "see" and be warned when the machine tool gets close to an existing utility. This paper will not only present the results of initial field tests but more importantly the results of an effort in integrating the EMI with a GPR (Ground Penetrating Radar) and some exciting applications for the future.
