Comparative Study on Bamboo and Steel Reinforced Light Duty Manhole Cover
Pranav Parab and Shilpa Kewate
One of the major environmental problems faced by construction industry is carbon emission from steel and cement manufacturing. Due to increment of carbon footprint in the environment, the earth's temperature is rising drastically. If this situation continues, humans as well as other living organisms on earth, may become extinct due to unfavourable environmental conditions. This study focuses on the reduction of carbon footprint from steel manufacturing by replacing steel reinforcement with bamboo which is an environment friendly and renewable material. The major drawback of mild steel and reinforced steel manhole cover is stealing due to high scrap value. An uncovered hole left on the road may result in endangering lives. This research paper investigated the use of bamboo reinforcement as a substitute for steel in the construction of light duty manhole. In this paper, manual design calculation along with software analysis using Finite Element Analysis (FEM) with ANSYS software and experimental testing for load resisting capacity as per IS 12592:2002 of bamboo reinforced manhole cover and its comparison is shown. This research work contributes towards sustainable development of green alternative material to steel.

Self - Redevelopment - Futuristic Method to Redevelop Buildings in Mumbai
Vinod Vanvari Sumedh Mhaske
Mumbai city is witnessing redevelopment of old buildings since last decade and a half. Current traditional concept of redevelopment is done among two parties that is the society and the builder. However due to various constraints, considerations and changing policies, the process of these projects becomes complex and complicated due to disputes between the society and the builder. The success rate of projects getting completed is as low as 25% to 30 % only. The projects either progress at snail's pace or get disrupted due to disputes and prolonged litigations. Self-redevelopment is a new trend that is now making its way in Mumbai's real estate market, where housing societies who do not wish to go with the developer, choose to redevelop their own buildings. Doubts persist about pitfalls of redevelopment of a property from concept to construction without a builder. This study reveals the various benefits, limitations and methods of self-redevelopment.

Prediction of Building Construction Cost Using Variable Selection
Viren B. Chandanshive and A. R. Kambekar
Estimating construction costs with a greater degree of precision early in the construction process is a critical factor in the construction industry. The aim of this research is to provide a cost estimation model applying Multiple Linear Regression (MLR) analysis to forecast the cost of building construction projects in India. For the development of the regression model, a total of 78 data sets of building construction projectswere collected from the Mumbai region, India. The most significant eleven cost variableswere applied as independent variables where as construction cost performs the role of the dependent variable. The enter, backward and forward methods were applied to build and develop the MLR models. The results obtained from the Enter method model show a stronger correlation test, with a value of 0.973 for the coefficient of correlation (R). The linear relationship between expected and actual costs was also defined by the coefficient of determination (R2), which was 94.6 percent. The Enter method revealed that the prediction is superior to that of the other two methods of regression analysis. With sophisticated statistical techniques, the designed regression model can quickly understand complex and broad data, improving the quality and consistency of decision-making. This study contributes to the Indian construction industry and delivers an effective concept about the project cost prediction modeling which will be helpful to the investors.

A Review on Module Mounting Structure (MMS) of Solar Photovoltaic Power Plant
Ashok Bhalkar and Abhijeet Wadekar
The capacity additions of the global solar photovoltaic power plant are beating all previous records and projections. With the capacity additions of 139.4 Gigawatt (GW), the cumulative installed capacity for solar photovoltaic (PV) has reached at least 760.4 GW by the end of 2020. This has led to the global decarbonising of about 875 million tons of CO2 equivalent. Prices of the solar PV module are decreasing and the PV power plant is becoming economical. However, prices of the balance of system (BOS) of the solar PV plant are still high and constant. Mounting structures are used to support the solar PV modules. Since the solar PV modules are built to last for 25 years, it is very important to choose the right mounting structure for the solar PV module which will support it for 25 years. Strong efforts are required to be made to reduce the cost and increase the reliability as well as stability of the solar PV module mounting structure (MMS). This paper reviews the literature of about last 10 years from 2010 to 2019, on the design and optimization of the rooftop and ground-mounted solar MMS. The prime objective of this paper is to provide an integrated, synthesized overview of the current state of literature available on solar PV MMS. This review identifies inconsistencies in the existing methodological approaches to the designing, manufacturing and installation of solar PV MMS. This review uncovers incremental insights into the standardization and formation of standard design codes especially for ground and roofmounted solar PV MMS.

Need of Protective Work-Wear for Workers of Indian Cement
Shweta Saxena , M.S. Parmar , Sangita Saini
Cement demand is closely linked to country's economic development, particularly in the infrastructure and housing businesses. The main growth factors for the cement industry are higher government spending on infrastructure and housing and increasing per capita income. This study aims to review and analyze the current status of cement industry with respect to the risks associated with the health of the workers involved. This study aims to provide guidelines,on how to control andon the areas to be focused by the employer for their better health and safety performance. Not only is it dangerous to work with dry cement, even wet cement can damage the skin because it is caustic, abrasive, and extracts moisture from the skin. India is world's second largest cement producer, and the demand for cement is further increasing due to its various applications.There are no specific protective workwear standards in India for the cement workers. The available workwear is inadequate to protect the workers from the dry or wet cement. Thousands of cement workers work under difficult hot, cold and humid climatic conditions without any protective work wear. This results in multiple health problems at the workplace. The present paper stresseson the need of a safe workwear for cement workers in India.
