NOW BASED ON THE ABOVE CONSTRUCTION SCHEDULE , THE EQUIPMENT AND MANPWER PLANNING PLANNING ie THE PLANNING FOR RESOURCE ASSIGNMENT IS TO BE DONE FOR THE ABOVE PIPELINE SCHEDULE.
FIRSTLY FOR THE PURPOSE OF EXECUTION THE PIPELINE IS TO BE DIVIDED INTO SECTIONS OF APPROPRIATE LENGTHS KNOWN AS SPREADS.I REQUEST YOUR ASSISTANCE IN FIRSTLY FIXING THE PROPER LENGTH , NUMBER AND ARRANGEMENT OF SPREADS ALONG THE PIPELINE.I HAVE ALSO TO LOGICALLY PRESENT TO MY MANAGEMENT THE JUSTIFICATION (PREFERABLY CALCULATION TOO - IF APPLICABLE) FOR FIXING THIS SPREAD LENGTH.
THEREAFTER THE RECOMMENDED DISTRIBUTION OF EQUIPMENT FOR EACH SPREAD (WITH RATINGS ie TONNAGE ETC OF THE EQUIPMENT) IE NO DOZERS , GRADERS , EXCAVATORS / POCLAIN ,ROCK - BREAKERS WITH HYDRAULICALLY OPERATED CHISELS,PIPE BENDING MACHINES PIPELAYERS/SIDEBOOMS , ETC IS REQUIRED TO BE PROVIDED.THIS DISTRIBUTION OF EQUIPMENT HAS TO BE LOGICALLY WORKED OUT AND IS TO BE BASED ON RECOMMENDED EQUIPMENT RATING , STANDARD MACHINEHOUR NORMS , AND TOTAL ESTIMATED QUANTUM OF WORK eg EARTHWORK / GRADING AREA ETC.
LIKEWISE RECOMMENDED DISTRIBUTION OF MANPOWER , WELDERS , RIGGERS , INSULATORS , ETC IS TO BE WORKED OUT BASED ON ESTIMATED QUANTITY OF WELDING LENGTH AND WELD VOLUME ETC AND STANDARD MANHOUR NORMS FOR PIPELINE WELDING ETC.
IT IS ALSO REQUIRED TO WORK OUT THE RATING AND DISTRIBUTION OF WELDING MACHINES FOR THE SPREADS SO CONSIDERED.
ALL THE MANPOWER AND EQUIPMENT PLANNING ABOVE IS TO BE PRODUCED IN A SYSTEMMATIC ,TRACEABLE AND VERIFYABLE MANNER.
ANY HELP FROM PEOPLE EXPERIENCED IN THIS FIELD SHALL BE HIGHLY APPRECIATED. ESPACIALLY I REQUEST HELP FOR FIXING OF SPREAD LENGTHS ,NO OF SPREADS, RECOMMEN
-DATION FOR RATING OF EQUIPMENT , MACHINEHOUR NORMS FOR EQPT WITH SPECIFIC RATING AND MANHOUR NORMS ESP FOR WELDERS.
IN ABSENCE OF DETAILS REGARDING HARD ROCK / ROCK STRATA AND SLOPE (IE TERRAIN)THE SAME CAN BE SUITABLY ASSUMED AT PRESENT AND THE ASSUMPTION SO MADE HAS TO BE CLEARLY MENTIONED.THE SAME CAN ME MODIFIED AT A LATER STAGE AS MORE AND ACTUAL DETAILS COME WITH SOIL INVESTIGATION AND TOPOGRAPHIC SURVEY.
