Developing Green Building Rating Tool (GBRT) for the State of Gujarat, India
Bhatt Rajiv and Patel Bhavin
Performance assessment of “Green Building” is essential to know its contribution towards achievement of sustainability. The study has been carried out to develop Green Building Rating Tool (GBRT) for the state of Gujarat of India. Criteria are selected from two Indian rating systems: Leadership in Energy and Environment Design (LEED INDIA Green Building Rating System) and Green Rating for Integrated Habitat Assessment (GRIHA). GBRT covers 37 major criteria from six major groups: Sustainable site planning, Health and well-being during construction, Material management, Water efficiency, Energy efficiency, Health and well-being post construction and Waste management. Based on feedbacks from 49 green building experts, criteria weights are developed with the help of Analytic Hierarchy Process (AHP). GBRT performance evaluation scheme has the range of score from 0 to 5. Final evaluation of a building as a Green Building is an interplay between performance score and global weight of criteria. The evaluator needs to collect performance data of building for 37 criteria and input it in the model. Rating of building would be in different categories like five star (score more than 4.5 out of 5) to one star (score less than 3). This rating tool can be useful for developers and builders to find out greenness of their building.

Determination of Key Progress Indicators for Construction Projects: The Contractor's Perspective
Shaila Maheshwari Jigar Mehta
In the present era, the construction industry is dynamic, especially in developing countries like India, where the lack of contractor's opinion at the planning stage often results in surplus resources causing time and cost overruns. It highlights the need of an effective performance evaluation system to ensure an efficient utilization of the available resources with essential safety measures. Such a system should incorporate the contractor's perspective which is based on their experiences from different sites to adhere to the best construction practices and correct (or eliminate, if necessary) the misconducts. For this purpose, the identification of critical parameters affecting the overall construction process is inevitable. This research performs a literature review and utilizes expert's opinions from the contractor's perspective to identify five Key Progress Indicators (KPI). These five indicators are Physical Progress Rating (PPR), Safety Performance Rating (SPR), Quality Performance Rating (QPR), Construction Methods and Planning Rating (CMPR), and Project Social Rating (PSR). After that, this study estimates the weightage of these KPIs using the Analytic Hierarchy Process (AHP) approach. For this purpose, this study develops a rigorous questionnaire to gather critical information from experts from the construction industry in India. This information provides input to the AHP approach for the determination of KPIs. The overall AHP analysis suggests SPR to be the most, while PPR and PSR to be the least important factors affecting the construction project performance.
A Scoping Review on Cloud Computing Applications in Construction Management
Gayatri Patil
Cloud computing is a fast-developing technology adopted by various organizations to allow their digital transformation. The present article reviews the use and research of cloud computing either in the construction industry, construction management, construction projects, or in construction technology. After a comprehensive search of the scientific literature some recent works are selected for review. This study identifies and analyzes the advantages and risk and its aim is to provide an overview of applications of Cloud Computing (CC) in the Construction Industry (CI). It explains the technical challenges faced in the area of digital technology. It comprises of websites and internet data (48%), journals (38%), conferences (7%), report/survey (3%), Blog (2%) and book (1%) and thesis (1%). It provides the capacity to impart data and information smoothly, operating quickly, effectively and is result oriented. Cloud connectivity is convenient and streamlining the workflow to help any business to become more workable, efficient, and productive. The companionship of Cloud Computing (CC) with other digital technologies such as Artificial Intelligence (AI), Building Information Technology (BIT), Big Data (BD) and others pertaining to the construction industry are dealt in-depth here with the futuristic role for them in the next decade. The paper covers benefits, drawbacks, use of software, and importance of construction management in higher education, and the future of cloud computing in the construction business.

Critical Evaluation of GRIHA Version 2019 Using Net-Positive Lens
Arun Chandramohan
One of the major sources of Carbondioxide (CO ) emissions in India is the 2 construction sector. Moreover, due to the increasing demand for energy in the real estate sector and shortage of supply, there is a high need to move towards sustainable buildings. The net-positive building is considered to be self-sufficient in energy and is also considered to have a significant reduction in carbon footprint. The net-positive evaluation utilizes net-zero criteria as the benchmark.The study critically evaluates the various criteria enlisted in Green Rating for Integrated Habitat Assessment (GRIHA) v.2019 (abridged version) using the selected applicable lenses viz., (a) degree of sustainability, (b) level of carbon offsetting achieved, and (c) level of disturbance to the natural environment.The study analyses each criterion in each section with the netpositive lens on reducing carbon footprint and evaluates the level of sustainability that can be achieved. This can facilitate the designers to adopt and modify the techniques that are incorporated into the project in the construction phase and post-construction phase to achieve net-positive rating or sustainability.

Safety Approach in Construction Industry Using Case Based Reasoning
Papa Rao, Sitesh Kumar Singh and V. S. S. Kumar
In developed countries, there is a large-scale mechanization in construction industry. The administration should focus on optimum use of resources such as men, machinery, and materials. Safety in construction industry is very important, since the rate of accidents is very high because of the dynamic nature of work. Over the years, hundreds of construction workers have died due to construction accidents. Many of these deaths could have been prevented, if the workers are better skilled on the hazards that they may face on the job-sites. Consuming drugs and alcoholism constitute a major group of accidents. In addition, accidents occur due to long hours of work, unhealthy and unsafe work conditions. As a result, many health problems occur along with fatalities. Suitable preventive measures are to be adapted to prevent the accidents in the project. Further, workers are to be educated by giving suitable training to reduce the accidents by conducting a number of meetings to minimize the accidents and suitable recommendations are to be made for effective safety programme. Thus, there is a need to develop a methodology to reduce accidents in construction Industry. This paper uses Case Based Reasoning (CBR) approach to forecast and to reduce the accidents in construction sector by providing suitable safety measures.
