This research paper aims to assort academic studies on IoT & big data applications, summarize logics behind using IoT & Big data in each application and extend understanding of current state of IoT & BD research in construction industry. This research follows a systematic literature assessment methodology to summarize the results over the last ten years and outline the research trends for applying IoT & BD in construction industry. IoT & BD are used in Safety Management, Surveying & Mapping, Construction Logistic Management, Construction Project Monitoring, Structural Health Monitoring, Smart Building Application, Waste Management & many more. Time efficiency and improved accessibility are the primary reasons for choosing IoT & BD in construction. The case studies provided have used IoT in every way imaginable to assist them in safety management, surveying and mapping, construction logistic management, construction project monitoring, and structure health monitoring, but they lack effective big data application. The challenges identified from literature were identified and results are as follows: The findings showed that the barriers related to "productivity reduction due to wearable sensors", "the need for technical training", and "the need for continuous monitoring" were the most significant, while "limitations on hardware and software and lack of standardization in efforts," "the need for proper light for smooth functionality", and "false alarms" were the least important barriers. The results obtained from this research not only offer new understanding for those in academia, but also offer practical guidance for stakeholders in the construction industry by identifying the main obstacles to the adoption of IoT and Building Information Modelling (BD) technologies.

The housing shortage in India around 18 million houses, majority of the needs in urban housing for economically weaker sections mostly. The housing provided in urban areas is in the form of multistoried residential apartment due to space constraints and high land cost. The cost of construction plays a major part in cost paid up by the end user .This construction cost takes up around 50-60% of the overall cost of the project .Looking closely at this cost of construction through appraisal of the Plinth area rates by CPWD one can observe the R.C.C. captures the major sector of the cost and the main constituents of this cost component comprises of concrete and steel. The design of structure commands the quantity of steel and concrete which can be reduced by reducing the dead load the structure has to support .Walls contribute a large share in the overall dead load , therefore by substitution of walling solution with...

The model is considered to have the best of both worlds, as it reduces the financial burden on concessionaire, by investment of 40% of the money during construction by government and return of 60 % of the investment by concessionaire in bi-annuity over a period of 15 year. This study's objective is to provide an evaluation of the hybrid annuity model used in road infrastructure projects by analysing the model's practical issues. Through an elaborate literature study model is understood in detail from the evolution of PPP in road infrastructure, need of new PPP model with evolution of Hybrid Annuity Model in road infrastructure, Changes in MCA documents, Process of Hybrid Annuity Model, Advantages and identified issues in HAM through various authors was understood. The study focuses on 32 case studies to identify the key factor that affects the outcome/performance of the project. Furth more, the identified issued was ranked on the bases of likelihood of their occurrence and severity through Relative importance Index. Identification key factors are a must to make recommendations to make the model more robust by addressing the major issues affecting the performance of the project

The variation is dependent on various factors. One of the major factors is the accessibility benefits available nearby the property, which is essential as one needs to commute almost every day for one’s own requirements. In the major cities of India, the most versatile option to commute is Metro Rail Transit System. Within the past few decades, Delhi NCR has faced rapid growth in urban development due to the improvement in road and highway systems as well as the introduction of new public transportation i.e. Metro Rail System. It has been almost 20 years till the commencement of Delhi metro but still a little research is available on its impact on real estate. So, the study focuses on identifying the impact of metro rail transit system on the cost of residential properties located around the metro stretch. There are various attributes of properties loc...

This study aims to develop a multi-criteria contractor selection framework that can incorporate multiple evaluation criteria along with the relative weightage. In this study, it has been identified that in India, as per the guidelines the contractor selection in the case of most popular Design Bid Build (DBB) projects is done based on Least Cost Selection (LCS) only. In LCS, the final selection is based on cost or bid price only. In some cases, Quality & Cost Based Selection (QCBS) is applied for contractor selection. However, QCBS is mainly used for consultant selection or selection of service providers. On the other hand, in many other counties, there are systems that follow multiple criteria for contractor selection to ensure the overall performance of the contractor. Hence, in India, there is a ne...

As a result the Indian banking system has been increased in NPA (Non-performing Assets) and restructured real estate projects during the recent years. With degradation in value the distressed assets don’t produce any profit in economy. Financial distress is a trending topic these days in finance and the project’s health is very important for investors as well as management. Investors deposit money in those projects which are financially healthy as risk of default is minimized for them, while management must be able to identify causes of distress which can be controlled by taking different measures. This paper deals with the elements of project financial distress as its major signs and sources as well as it suggests ways to eliminate the consequences. This result provides an effective way to resolve financial distress by restructuring it. Restructuring a project is always a better option in compa...

The SERVQUAL model covers five dimensions-tangibles, reliability, responsiveness, assurance and empathy. This survey will help in strategic planning and decision-making regarding further improvement of Community College's services to students. This paper aims to assess students' satisfaction with their experiences at Community College, CURAJ through a Student Satisfaction Survey. A questionnaire based on five point Likert scale covering various dimensions of service have developed, put to pilot test and then administered to all students of the community college. Presently there are four batches of the B.Voc. (Interior Design) Programme. Few open ended questions will also be included in the questionnaire to assess the weakness and strength of the community college at CURAJ. The reliability of the data collected will be checked by using SPSS and the student inputs will be analyzed according to the principle of weighed averages. This survey will provide valuable information about perceived service gaps and other inputs to support strategic planning and decision-making at community college and thus help to improve quality of programmes and students' services.
