Importance of Labour Efficiencyin Dry Dock Construction

Abstract

This research paper aims to define and evaluate factors affecting labor productivity in the construction site.A formal questionnaire survey was used as the tool for collecting data from the workforce from dry dock construction. The data collected were analyzed using the index of relative importance (RII) to rank the variables based on their relative importance. Suitable recommendations were made to working pattern considering the survey results and this showed an increment in the labour productivity. In this study the responses was collected from the thirty professionals working on the dry dock construction site. Based on the RII value the responses were analyzed and top ten factors were selected that influences the labor productivity the most. After implementing suggestive measures in four teams, productivity was improved and as a result baseline productivity for all four teams was almost around 350 kg/man. Improving productivity can help to reduce time and cost at the construction field.
