The Civil Engineering Laboratory CEL, under the sponsorship of the Naval Facilities Engineering Command NAVFACENGCOM and for proponents associated with the construction forces of the Navy and Marine Corps, has for several years been experimenting with automatic surveying and with retrofit automatic control kits for construction equipment. Most recently, an experimental automatic blade control kit was developed for the Case 450 tractor with poyer-tilt and power-angle blade, as stocked by the Marine Corps. Initial laboratory testing showed that the tractor with the kit was capable of performing finish jobs normally requiring a grader in addition to the heavier, rougher tasks on which the dozer is ordinarily used. This report describes field trials conducted in March 1976, to confirm that capability by direct comparison and measurement, and to determine any savings in job time and labor resulting from use of the new equipment. Both the automatic surveying and the automatic blade control kit were included in the trials. The results indicate the savings possible using this equipment are substantial.
