Time Performance Improvement by Supply Chain Management and 4d Building Information Modelling (BIM 4d) Integration Implementation on Wastewater Treatment Plant

Abstract

Current trends in the world are related to wastewater treatment problems. One of the factors is the still low capacity of urban and industrial wastewater treatment in the world due to the delay in the implementation of waste water treatment plant construction. On average in the world, construction of waste water treatment plants is experiencing a 20% delay.

To overcome the delay in the construction of the waste water treatment plant by examining the implementation of Supply Chain Management and 4D BIM in the construction of a waste water treatment plant. By using statistical analysis methods using Statistical Package for the Social Sciences (SPSS) regarding the factors that influence the application of Supply Chain Management and 4D BIM scheduling methods in the construction of the Waste Water Treatment Plant.

The results of this study indicate the influencing factors include: Scheduling, Coordination between project parties, efficient model-ing strategies, Supplier selection, Availability of information and technology, Availability of materials, Knowledge of environmental regulations, Availability of resources, Costs, strategy, Construction delays, and Changes to specifications.
