COMPUTER SPEEDS MONITORING OF FILL AND BASE CONSTRUCTION

EARTHWORK AND BASE CONSTRUCTION IS MONITORED IN MINNESOTA BY THE COMPUTER. THE NEW COMPUTER PROGRAM BY ITS SPEED, IS HELPING TOWARD COMPLIANCE WITH MOISTURE, DENSITY, AND GRADATION SPECIFICATIONS AND TESTING RATES. FIELD DATA ARE COLLECTED ON EMBOSSED PLASTIC CARDS WITH BASIC PREPUNCHED DATA AND OPTICAL MARKER IN INPUT FORM. THE INPUT FORMS ARE MARKED IN THE FIELD AND SUMBMITTED TO THE CENTRAL OFFICE ONCE A WEEK. THEY SHOW ALL FIELD TEST DATA AND APPLICABLE SPECIFICATIONS. THEY ARE SCANNED BY AN OPTICAL MARKED PAGE READER WHICH READS IMPUT FORM AND PUNCHES A CODED CARD FOR EACH TEST. THE PUNCHED CARDS ARE THEN INSERTED INTO THE COMPUTER WHICH SORTS THE DATA, COMPARES THE TEST RESULTS TO THE SPECIFICATIONS AND PRINTS A REPORT. DATA ARE THEN STORED ON A MASTER TAPE FOR FUTURE REFERENCE. DURING THE 1966 CONSTRUCTION SEASON, THE PROGRAM WAS TRIED ON AN EXPERIMENTAL BASIS ON SEVERAL SELECTED PROJECTS TO DETERMINE THE FEASIBILITY OF USING THE SYSTEM STATE-WIDE. BY THE END OF 1966 THE SYSTEM WAS READY TO GO STATE-WIDE BUT IT WAS INITIATED GRADUALLY BECOUSE OF THE PROBLEM INVOLVED IN TRAINING PERSONNEL. ABOUT THREE FOURTHS OF ALL THE STATE CONSTRUCTION PROJECTS ARE NOW INCLUDED IN THE PROGRAM. THE PROGRAM HAS RESULTED IN A LARGE SAVINGS IN MAN HOURS IN THE MATERIALS OFFICE. IT HAS BEEN DETERMINED THAT: (1) THE PROGRAM IS FEASIBLE, (2) THE IMPLEMENTATION OF THE PROGRAM SUBSTANTIALLY REDUCED THE COST OF MONITORING FIELD CONSTRUCTION, PREPARING MATERIALS CERTIFICATES AND HAS RELEASED ENGINEERING PERSONNEL FOR MORE MEANINGFUL WORK, (3) THE PROGRAM MADE IT POSSIBLE TO CERTIFY EMBANKMENT AND BASE ITEMS ALMOST IMMEDIATELY UPON THE COMPLETION OF THE WORK, AND (4) THE BASIC PROGRAM CAN BE ADAPTED TO OTHER AREAS SUCH AS BITUMINOUS CONSTRUCTION, CONCRETE CONSTRUCTION AND LABORATORY TESTING TO PROVIDE DATA FOR THE DEVELOPMENT OF STATISTICAL SPECIFICATIONS AND TO DETERMINE THEIR FEASIBILITY.
