A STUDY OF WASTE IN INDUSTRIALISED BUILDING SYSTEMS

PRODUCTIVITY IN CONSTRUCTION IS A SYSTEM-WIDE ATTRIBUTE RATHER THAN ONE LOCALIZED TO THE MANUFACTURING PLANT OR THE SITE. IF FAULTY MATERIALS, PROCESSES, OR PRODUCTS ARE USED AT THE PLANT, THEN THE HIGH MORTALITY IN ASSEMBLIES AT THE BUILDING SITE WILL REDUCE OVERALL PRODUCTIVITY. THE GENERALLY ALLOWED WASTE OF 7--9% IS WELL BELOW THE ACTUAL AVERAGE, WHICH IS OVER 15%. AN EIGHT-MONTH STUDY OF LARGE PRECAST CONCRETE COMPONENTS REVEALED THAT 70% OF DAMAGES OCCURED AT THE FACTORY AND THE REMAINING 30% EITHER IN TRANSIT OR AT THE SITE. THE MAIN PROBLEM IS THAT THE CONCEPT OF ACCEPTABILITY IS SO VAGUE AND RELATIVE THAT ITS INTERPRETATION IS LEFT SOLELY TO THE SKILL AND ABILITY OF THE INDIVIDUAL IN CHARGE. IN THE CASE OF BULKY COMPONENTS, SUCH AS CONCRETE SLABS, STANDARDIZATION OF QUALITY CONTROL IS RENDERED DIFFICULT. IN SYSTEM BUILDING IT IS VITALLY IMPORTANT TO LAY OUT THE PRODUCTION PROCESS IN SCHEMATIC FORM, IDENTIFY THE VARIOUS TYPES OF PRODUCTION FAULTS, RELATE THESE FAULTS TO THE STEPS IN THE PRODUCTION PROCESS, IDENTIFY THE QUALITY CONTROL CHECKS APPROPRIATE TO EACH STEP, ASSURE ADEQUATE SUPERVISION OF THE QUALITY CONTROL PROCESS (WHICH ENTAILS THOROUGH TRAINING AND GOOD TECHNOLOGICAL UNDERSTANDING), AND PROVIDE EQUIPMENT AND PROCEDURES SUITABLE FOR THE INDIVIDUAL QUALITY CONTROL OPERATIONS. EACH OF THESE REQUIREMENTS IS ILLUSTRATED, WITH PARTICULAR ATTENTION TO A SURVEY OF PRODUCTION FAULTS.
