ECI – Engineers Construction

ECI recently acquired a Ditch Witch 4020 All Terrain.  The 4020 AT is a dual drill pipe system that allows efficient drilling in rock conditions and difficult soil conditions.   The inner drill pipe drives a rock bit at up to 250 rpms and 2,000 ft-lb of torque while the outer drill pipe achieves up to 5,000 ft-lb of torque.  The 4020 AT has a pull back force capability of 40,000 lb.

We currently have the 4020 working on a waterline project where it is drilling 6.5-inch-dia pilot holes ranging up to 800 feet long.  We are supplementing the 4020 with our Ditch Witch JT100 for the backreaming and pullback operations.

The 4020 AT provides ECI with complete and competitive  HDD capability in all types of soil conditions.   ECI has variety of trenchless capabilities and equipment with a full line of directional drills ranging from our Ditch Witch 920 up to the JT100, pneumatic piercing and hammers ranging up to 24 inches, and auger/jacking boring rigs up to 42 inches.
