Improving Construction Efficiency And Productivity Of Industry Using SPSS

ABSTRACT The most challenging issue in Construction industry is to improving the production efficiency. India is a growing economy. It is estimated to be the third largest economy by 2050. Infrastructure growth is a stepping stone of a stable and productive society, it presents unique challenges but also brings opportunities for private and public sectors in the field of construction. Development will lead to massive construction and there will be a positive growth in industries related to construction. Reports also suggest that the upward trend has been witnessed by these sectors. This study reports the results of a questionnaire survey of project managers, site engineers, supervisors and craftsmen, in India, to identify the factors influencing construction labour productivity. The top five factors identified as having a significant impact on productivity: (1) Timely availability of materials at the worksite, (2) delayed material delivery by the supplier, (3) Strikes called by political parties (4) Frequent revisions of drawings/design, resulting in additional work/rework and (5) Timely availability of drawings at the worksite. The findings provide a better understanding of the factors influencing productivity in the Indian context and will aid construction practitioners in making effective plans for productivity improvement by using management software SPSS.
