UTILIZING BUSINESS MACHINES IN TRAVERSE AND EARTHWORK COMPUTATIONS

AS AN AID IN OVERCOMING THE CRITICAL SHORTAGE OF ENGINEERING MANPOWER, THE CALIFORNIA DIVISION OF HIGHWAYS HAS INVESTIGATED AND INSTITUTED PROCEDURES FOR CALCULATION OF TRAVERSE AND EARTHWORK DATA BY MEANS OF PUNCHED CARD EQUIPMENT ALREADY AVAILABLE IN THE CALIFORNIA HIGHWAY PLANNING SURVEY TABULATING SECTION. THIS PAPER OUTLINES THE GENERAL PROCEDURE USED BY THE ENGINEER IN PREPARING THE BASIC INFORMATION FOR COMPUTATION OF TRAVERSE AND EARTHWORK DATA. SAMPLES SHOW, ON A STANDARDIZED COMPUTATION SHEET, THE REQUIRED METHOD OF RECORDING THE FOURTEEN DIFFERENT PROBLEM TYPES CURRENTLY BEING PROCESSED. THE RESULTS ARE LISTED MECHANICALLY ON A STANDARIZED TRAVERSE FORM. ELEVEN SAMPLES FOR EARTHWORK COMPUTATIONS ARE ALSO INCLUDED, FIVE OF WHICH SHOW THE ACCEPTABLE METHODS OF RECORDING THE TERRAIN NOTES, AND THREE THE METHODS OF RECORDING THE ROADBED NOTES. ALSO SHOWN ARE A METHOD OF RECORDING DATA FROM CONTOUR-GRADING PLANS, A METHOD OF RECORDING ADDITIONS TO THE COMPUTED QUANTITIES FOR USE IN COMPILING DATA FOR THE MASS DIAGRAM, AND A SAMPLE OF A SUGGESTED FORM FOR TRANSMITTING THE DATA TO THE TABULATING SECTION. INCLUDED IS A SAMPLE OF THE TABULATED RESULTS OF EARTHWORK COMPUTATIONS WHICH IS RETURNED TO THE ENGINEER. THIS TABULATION LISTS THE VOLUME OF EXCAVATION AND EMBANKMENT BETWEEN EACH CROSS SECTION AND GIVES TOTALS FOR EACH STATION. THE DATA FURNISHED WILL ALSO ENABLE THE ENGINEER TO PREPARE A MASS DIAGRAM. THIS PAPER ALSO OUTLINES SOME OF THE CHANGES IN PROCEDURE NECESSARY ON THE PART OF THE ENGINEER TO MAKE FULLEST USE OF THIS COMPUTING SERVICE. WHILE THE WHOLE PROCEDURE CALLS FOR A SOMEWHAT DIFFERENT APPROACH TO THE PROBLEM ON THE PART OF THE ENGINEER, IT HAS BEEN FOUND THAT THE SAVINGS IN BOTH TIME AND MONEY HAVE MADE THIS SERVICE WELL WORTH THE EFFORT. /AUTHOR/
