HORIZONTAL CONTROL STAKING BY TRIANGULATION WITH COMPUTATIONS BY COMPUTER

THE DEVELOPMENT AND USE OF A METHOD FOR ESTABLISHING A HORIZONTAL CONTROL SYSTEM FOR STAKING COMPLICATED GEOMETRICS ON THE GROUND IS DESCRIBED. MAJOR CONTROL POINTS WERE ESTABLISHED OVERLOOKING THE PROJECT. CONSTRUCTION STAKES COULD THEN BE 'CUT IN' FROM AT LEAST TWO CONTROL POINTS BY USING DIRECTIONAL THEODOLITES. THE DATA FOR EACH CONTROL POINT, INCLUDING CLOCKWISE ANGLES FROM AN ESTABLISHED REFERENCE POINT TO DESIRED CONSTRUCTION STAKES, WERE PREDETERMINED. CALCULATIONS BASED ON COORDINATES WERE MADE BY USING VARIOUS GEOMETRIC PROGRAMS DESIGNED FOR THE IBM 650 COMPUTER. THE OUTPUT INFORMATION FOR EACH CONTROL WAS PRINTED AND BOUND INTO A CONVENIENT FIELD BOOK SIZE VOLUME, THUS COMPLETELY ELIMINATING THE NEED FOR FIELD COMPUTATIONS. THE AUSTIN PROJECT IS NEARING COMPLETION AND THIS METHOD OF STAKING HAS PROVED EFFECTIVE IN OBTAINING INFORMATION NECESSARY FOR PLAN PREPARATION, ADJUSTMENTS OF UTILITY LINES, AND THE MOST IMPORTANT PHASE--THAT OF TRANSLATING THE GEOMETRIC DESIGN OF THE PLANS TO CONSTRUCTION STAKES IN THE FIELD. /AUTHOR/
