Siddesh Pai and Amber Shukla
The labour camps were considered temporary and portable structures mostly situated in remote areas with no power availability and using diesel generators was the only option. It was prerogative of every construction companies to focus on the well-being of its workers as well as care for the environment. There was therefore a need for green power generation for clean and noise-free environment for labour camps by installing a solar power solution that would power the camp independently and stop using diesel. It meant that all of the power gluttons like ACs, Electric Pumps, Kitchen Appliances, Water Heaters, Chillers, Lighting systems etc. operated on the ecological solar power energy. The camp could operate all the electric appliances in the night as well, which stored the energy during the day light. This technology could be a huge motivation to all the companies and also would help to reduce the carbon footprint to a great extent thus contributing to the sustainable energy policy of the nation. This research focused on using Sustainable power generation using flexible photovoltaic solar panel technology for labour camp housing at construction sites. This study attempted to research various parameters like flexible solar panel design and specifications, power generation costing, capacity utilization and availability of resources. The research paper focused on studying the combination of solar energy and tensile structures and the parameters on which the solar panels could produce energy. Different case studies were researched to explain these parameters. Solar power is indeed sustainable, environmentally friendly & renewable source of energy

A Case Study on First Deep-Sea Port in India (Vadhavan): Development Versus Environment Debate
Jonardan Koner and Avinash Purandare
Maharashtra has only two major ports i.e. Jawaharlal Nehru Port Trust (JNPT) and Mumbai Port. Both the ports are constrained in the evacuation of cargo for the past several decades due to the development of the city around them. Also limited depth in the harbour allows only small ships to berth and this becomes a major constraint. After considering these factors, the Indian Government approved the development of a greenfield, deep-water port at Vadhavan. Vadhavan port will be developed on "landlord model". A Special Purpose Vehicle (SPV) will be formed with Jawaharlal Nehru Port Trust (JNPT) as the lead partner with equity participation equal to or more than 50% to implement the project. The SPV will develop the port infrastructure including reclamation, construction of the breakwater, besides establishing connectivity to the hinterland. All the business activities would be undertaken under Public Private Partnership (PPP) mode by private developers. The JNPT has proposed to develop Vadhavan Port along with the participation of Government of Maharashtra and Maharashtra Maritime Board. This project will be jointly implemented by JNPT and Maharashtra Maritime Board with a shareholding of 74% and 26% respectively. The notification of Vadhavan Port as a major port is published in the official Gazette of Government of India (GOI) on 19/02/2020. Detailed Design and detailed Engineering is in progress through consultant and it will be completed by July 2021 for requirement of investment decision of Government of India. The building of local opinion above Vadhavan Port project is in progress. The Vadhavan project was essentially conceived as a satellite facility to JNPT, the country's busiest public container harbor, which had become saturated until Port of Singapore Authority (PSA) International opened the first phase of a 4.8 million-TEUs (twenty-foot equivalent units) terminal in February 2018. The government estimates the new project will require an investment of Rs. 65,544.54 crore, or approximately USD 9 billion.

Vishal Kumawat, Nirank Jadhav, Shubham Shinde, Saurabh Sonar, Manish Pal and Arpita Mathur
This Case study is about exploring ancient construction materials and construction practices which are Sustainable in nature. For this case study the area of interest was Raigad Fort which is located in Mahad, district Raigad, Maharashtra. The fort has a very rich history and heritage hidden in it. Construction of the fort is marvelous and techniques used in the olden days were our traditional Indian techniques which have its own essence; but these techniques and practices have faded as time passed. This case study is about learning from our own traditional sustainable techniques and using them in our modern construction. As construction in India is growing with an immense speed, we are damaging the environment equally. It is high time to bring sustainable construction into picture. For data collection we have interviewed engineer, architect and archeological expert who are familiar with the fort and have been working on it. The conversations took place over video conferencing and voice calls. We have obtained data through these calls and found that it is possible to bring in sustainable practices into construction. Looking at the data available about our own old traditional construction practices and construction techniques we can use some of those into our modern construction and make it more sustainable and environment friendly, by replacing or substituting conventional construction practices and materials. We have found some of the practices from the case which can be implemented in our era, and these practices and materials will impact less on the environment making it more eco-friendly and even economical. If we are not able to implement whole of the old traditional practices, we can pick up some of them and apply it into our conventional construction practices so that it will make a difference in bringing sustainable and our own traditional techniques, practices, materials back into picture. Though it will become a need if we look at the consumption rate of the construction industry in current date, we should consider sustainable construction practices as a matter of interest.

Samruddhi Wagh, Deep Patel, Sourav Kumar Singh, Rajani Kumari, Himgauri Patil and P. K. Samanta
The wealth of any nation is judged by the infrastructure it provides through its construction industry. The construction industry is a large and volatile business sector. Thus, the process of performance assessment and corrective measures for this industry is imperative. Previous studies on performance measurement focused on only the financial perspective. But in the longer run, for the construction industry due to the involvement of numerous stakeholders, a wholistic consideration of performance is necessary, Key Performance Indicators (KPIs) are considered one of the means for measuring performance and progress towards objectives of the organization and help organizations and agencies to identify and measure their progress toward specific objectives. This paper aims to study the performance indicators (PIs) used by the business managers in the civil construction sector. A questionnaire was applied to a sample of construction companies from this region. A statistical analysis of the data collected allowed to identify the most important and most used performance Indicators for the companies that were surveyed. Furthermore, with the help of these selected KPIs, the performance of a large cap infrastructure company in India was analysed. The integration of BSC and the SWOT analysis of the company helped to direct us in what areas does the company needs to focus in order to achieve its objectives. . This study also helped to understand the measures taken by these companies for the betterment of their performance scores based on these KPIs. Furthermore, this study also aims to analyse the criteria to select the PIs, its benefits and the extent of use of this method in the construction sector and form a multidimensional framework for an effective measurement of the construction sector performance.

Construction Equipment Cost Management
Avik Munshi and Devanshu Pandit
In the last century, construction equipment emerged as means to replace human labour and increase productivity. Today the construction industry has become highly mechanized, and equipment has gained significance within contracting organizations. However, as construction equipment enter the maturity phase of product lifecycle, increased access to equipment has ruled out certain competitive advantages that resulted from mere possession of equipment. For instance, leasing options have eliminated the need of initial capital outlay while enabling organizations to compete in the market. Hence, as the industry becomes more competitive with more players, each with access to means including labour and equipment, the competitive advantage of construction equipment has shifted from mere possession to proper management. Moreover, as equipment play a major role in execution of construction projects, construction equipment not only forms a major portion of assets but also contributes a major portion of project costs. Thus, understanding the cost structure of construction equipment is critical to bidding success as well as profitability of organization. Much research and theory regarding construction equipment is available, most of them addressing the individual cost aspects. The compiled theory that is available is much theoretical and too extensive to be utilized practically, leaving a dearth of compiled and elaborate summary that can assist the management in cost estimation and decision making. Hence, this paper compiles all such individual aspects and corroborates as well as contrasts the theory with the experience and observations of industry professionals. Furthermore, it also states observations and draws inferences for insights.

Jonardan Koner, Bedabrata Bhadury and Avinash Purandare
The development of road transportation network in the north-eastern region is especially important for the socio-economic development of the region. Infrastructure Development is the backbone of economic development for a country's economy. After 1951 India's five years plans made infrastructure development a priority area with over fifty percent of funds being allotted to it. The production and sales of goods and services is a very important factor for the growth of the economy. Infrastructure performs the role of providing inputs for the goods and services sectors. In the marketing of goods and services it plays an important role as it makes goods and services reach from the production centers to the markets. The creation of Bangladesh severely affected the connectivity of the North Eastern States with the rest of the country. Within the north eastern states several factors affected the socio-economic growth of the region including the insurgency problem, lack of infrastructure, poor connectivity with markets and the lack of all-weather road connectivity. The average road density in the region is much lower than the rest of the country. Road transportation connectivity will play a key role in the socioeconomic growth in the north eastern region. The improved road connectivity in the north eastern region will definitely lead to economic and social development in the region.

Sanchit Jadhav , Gollu Vamsi Krishna , Shivaswaroop D O and Poulomee Ghosh
Rapid urbanisation in India calls for transportation solutions like urban metro rail projects. However, multiple metro projects that are being implemented in Indian cities suffer from a various issue that affect performance in terms of deadlines, project cost as well as construction quality. This research has prioritised the parameters of time and cost overrun based on the likely severity through expert's questionnaire survey. Relative Importance Index (RII) of collected responses were computed and analysed. The results show that for time overrun the top three critical factors are land acquisition, change in government/policies/regulations and force majeure. Similarly, the top three critical factors for cost overrun are time overrun of the project itself leading to increase in cost, change in government/policies/regulations, force majeure are some of the most critical factors of cost overruns. Mitigating these risks through proper life cycle contract management and risk allocation would facilitate timely completion of the metro projects with justified value for money to the government.

Sudarsan J S Vignesh A , Udaya S and V. Sri Hari
Due to increase in population and India is being one of the developing countries in the world, demand of consumption of energy increases rapidly. Several problems like global warming, greenhouse effect and climate change occurs due to rapid consumption of non-renewable energy resources. To get the better of these energy crises and to attain sustainability in energy consumption, a trial study was conducted and carried out. To identify the efficiency of the concept, a trial study was executed using kitchen waste from an educational institution mess with average student strength of 6500. A prototype of 3m3 anaerobic digester model is developed. Biogas plant was set up in the institution and biogas is generated from the mixed kitchen waste generated in hostel mess. The institution where we conducted the study consists of 4 messes. The study was conducted only in one mess. Anaerobic digester is fabricated and made readily available for kitchen waste to decompose for faster production of biogas. It is estimated and found that the average waste generated per person is be in average of 250g. Therefore, nearly 700kg to 1400kg of biogas can be generated. Firstly, the kitchen waste and cow manure is mixed in the ratio 2:1 and filled two-third of the digester. It took nearly 30days for the gas to produce. The gas is collected in an airtight bag like container and further it is being used for cooking in mess and the slurry used as a manure in farming. This will be a best alternative of moving towards sustainability.
