Construction sector has always been dependent on manpower with most of the activities being labour intensive. Project productivity, thus, depends directly on productivity of labour. Enhancing labour productivity would contribute to overall success of the project. In order to improve labour productivity, associated factors need due consideration. Total interpretive structural modeling (TISM) is implemented as a methodology for identifying and summarizing relationships among factors which affect productivity of labour. 10 most significant factors negatively affecting construction labour productivity are considered for developing model that establishes interpretive relationship among these factors. The result shows that material shortages, tool/equipment shortages, drawing & specification alterations during execution and working seven days per week without holiday have strong driving power and weak dependence power and are at the lowest level in hierarchy in the TISM model. Lack of labour surveillance and lack of labour experience have strong driving and strong dependence power. Top management of the project must stress on variables having high driving power so as to facilitate improvement in the overall productivity of construction site.

The construction industry is multidisciplinary in nature and various operations are executed at the same time. One of the major resources for executing construction operations is the human workforce. Management of this workforce with effective safety provisions is a prime factor for reducing accidents on construction sites. Nowadays, technologies such as Building Information Modeling (BIM) offer the potential to manage safety on-site with their automatic safety checking capability. BIM is a model-based smart nD platform that offers tools for architecture, engineering, and construction proficients to plan, design, and manage construction activities more efficiently. Despite its growing use globally, BIM has not been adopted sufficiently in the Indian construction industry. This paper presents a bibliometric analysis of the adoption of BIM in the global construction and the Indian construction industry. It also reviews the adoption of BIM for safety in the global and Indian construction industry. The bibliometric analysis is carried out in two phases, at first it reviews the adoption of BIM globally, and limits the findings to cover BIM adoption in the Indian construction industry. Secondly, it reviews the adoption of BIM for safety in global construction and limits the findings to cover BIM adoption for safety in India. Various complementary tools such as VOSviewer, iMapbuilder have been used for data analysis. The research highlights the need for BIM in India particularly for safety on construction sites.

Construction industry is highly exposed to accidents than other industries. Due to the multi-disciplinary nature of the construction industry, more than one task is required to be performed at the same time. If safety planning is improper, it may lead to serious accidents on-site, directly affecting overall productivity. Recent technologies such as Building Information Modeling (BIM) have the potential to manage safety on the construction site. This study deals with the status check of the awareness of BIM in Indian construction along with benefits, barriers faced in Indian construction. This study also presents the benefits that BIM implementation can bring for safety management. In this study, a questionnaire was designed to ascertain the level of awareness of BIM in the Indian construction industry. The questionnaire was distributed to construction professionals from all over India. A total of 171 valid responses were received from all the corners of India. Statistical Package for the Social Sciences analysis (SPSS) has been used for data analysis. The survey concludes that the Indian construction sector needs to work on the three main aspects that include awareness of BIM and its benefits for organizations, accumulation of BIM in the tertiary education system, and delivering corporate training in construction organizations for a successful realization of benefits by the implementation of BIM.
