Assessment of Productivity Constraints in Building Construction Industry

Abstract

Abstract: Construction management deals with planning, organizing, securing and managing resources to bring out the successful completion of specific engineering project goal and objectives. Assessment of productivity in construction industries includes identifying the key constraints to on site labor productivity and improvement measures.This study aims to identify the key constraints to on-site labour productivity and improvement measures. Using the descriptive survey method, views of some project managers, contractors and subcontractors in Kolhapur was canvassed via pilot interviews and questionnaire surveys at the qualitative and quantitative data gathering stages, respectively. Multi-attribute technique was used to analyse the quantitative data. Results showed that the key external constraints to on-site labour productivity comprise, in order of decreasing impact, statutory compliance, unforeseen events and wider external dynamics. The internal constraints were found to have much higher impact on onsite productivity than the external factors. In order of diminishing levels of impact, the internal constraints comprise reworks, level of skill and experience of the workforce, adequacy of method of construction, buildability issues, and inadequate supervision and coordination.The factors underlying each broad category of external and internal constraints are reported. The relative levels of impact of the identified constraints are expected to guide the project team in addressing the constraints in a cost-effective manner.
