Abstract:
Construction productivity helps us to judge the performance of a construction project. Construction industry is one of the largest industry in the world. It accounts for 13 % of the world’s GDP. Since it holds so much significance, we need to analyze the factors that play a vital role in controlling its productivity.
Construction process is a combination of activities. There are various factors that affect the productivity of different construction activities; some are tangible and other are intangible. The study aims to establish a relationship of productivity of with its tangible and intangible factors. The study was done at the first (basic) level of productivity i.e. activity level. Activities selected were: concreting, rebar installation, brickwork and shuttering. The tangible factors were measured by calculating the direct work being performed at different construction sites and the intangible were measured through direct work, questionnaire and performas. Research was conducted at four different construction projects in the Islamabad region.
Firstly, we carried out the literature review to find out the details and research already done in this field. We went to the construction sites to collect the selected activities data in regard with our factors and recorded it on a data sheet. Once field data collection is complete, we plotted graphs of productivity against its factors to determine their relationship.
