Affordable housing is a problem that many countries are taking stock of, world over. In India, the problem is much more stark with an estimated shortage of around 18 million houses, with 99% of this in the economically weaker sections of society. This paper sets out the definitions of affordable housing in India and across the world; the issues with the various definitions of affordable housing; the institutions and agencies responsible for formulating and implementing affordable housing policies in the state; the opportunites and challenges in affordable housing as well as a discussion on learnings from international experience in this sector. The Government of India (GOI) had estimated a shortage of more than 18.78 million homes at the beginning of 2012, of which 95% were in the EWS (Economically Weaker Sections) and LIG (Low Income Group) segments. Further, the country’s total urban housing shortage is projected to be about 30 million by 2022. The Indian Government currently faces an uphill task of providing for more than 2 crore dwellings by the year 2022, which translated to almost 3 million units per year to fulfill its electoral promise of ‘Housing for All by 2022’. To achieve this daunting target the government has taken various initiatives to make the affordable housing segment lucrative both for the private developers and the homebuyers. This research paper aims at assessing the impact of the government initiatives on both the parties, i.e., the private developers and the homebuyers and tries to encapsulate their views on the government policies to boost the segment. Affordable housing refers to delivering cost-effective dwelling units for those families whose income is below the median household income of the society. It is a crucial issue especially in developing nations where a majority of the population is not able to purchase houses at the market price. In the present scenario of complex, expensive and high-quality projects, profit margins have shrunk due to tough competition between developers. Hence for providing affordable housing solutions it becomes imperative to make best utilization of resources by employing efficient technologies and optimization techniques.Currently, a major drawback of the construction industry is lack of proper data flow and its management. Data is managed either on physically maintained drawing sheets or computer aided drawing and drafting tools, due to which various construction parties like the architect, the contractor, the structural engineer, the MEP, etc. Work on different platforms with their individual expertise. Hence, often the projects are impacted due clashes in members of the structural, non-structural, mechanical, electrical, plumbing and other service utility elements. Moreover, if any change is envisaged by a party, it needs to bring to the notice of all other concerned parties and all need to rectify their individual drawing plans, sections and elevations, which leads to loss of time or rework.One challenge that many projects face is the escalated construction costs. This is due to materials, equipment and other resources being procured and employed according to individual project needs, availability and expertise. Also, contractors invest a lot of their resources in construction of common utilities, which are piecemeal, and would otherwise be taken together with other projects. This is due to lack of data available with municipality and urban local bodies, let alone the contractors. Many activities are duplicated for different projects due lack of synchronization. Thus, if a group projects are brought on a common geographical platform where their spatial and non-spatial requirements can be serviced, it will lead to considerable saving for all the parties involved. Geographical Information System (GIS) is one such tool which can be used as it has the ability to create, store , manipulate and analyze.

The work of Construction Companies involves a certain amount of risk when design projects are undertaken for buildings and other structures, as well as for other projects such as roads and runways, pipelines, sewerage- and water works and pump stations. Accepted levels of risk for these companies when accepting a particular appointment from a client are not always adequately quantified at the beginning of the project. This puts the company in a position where it may be subject to professional indemnity, claims from clients and from the public, should something go wrong during a particular project. The risk taken by the consulting engineer can to a large extent be quantified, and timeous mitigation measures can be taken to prevent certain things from occurring that may pose a threat to the successful construction and later use of the facility. As it is, the civil and structural engineering industry has a reputation that many projects run late and are over budget, not to mention the technical difficulties that might arise during the course of the project. This situation can to some extent be avoided by the introduction of a Quality Management System (QMS), which, if implemented and used correctly, should be able to identify and mitigate most of the risks that might arise from any project. Companies will therefore introduce a QMS into their company for this purpose, and will train their employees in the use of the QMS.
Case study of hostel project
(AIKTC, 2018-05) Parkar, Fauwaz; Harbe, Aaquib (12CE66); Shaikh, Arfaat (13CE48)
Hostels provide budget-oriented, cost-effective, sociable accommodation where guests can rent a bed, usually a bunk bed, in a dormitory and share a bathroom, lounge, and sometimes a kitchen. Hostels are often cheaper for both the operator and occupants, many hostels have long-term residents whom they employ as desk agents or housekeeping staff in exchange for experience or discounted accommodation.
Case Study: Application Of Mathematical Techniques On A Construction Project
(Yadavrao Tasgaonkar Institute of Engineering & Technology, 2013-03-06) Parkar, Fauwaz
With the continuous decline in profit margins and increased competition in construction projects, construction contractors are finding ways of eliminating waste and increasing profit. Although numerous approaches have been developed to improve efficiency and effectiveness of construction processes, implementing statistical techniques offer the promise to minimize, if not eliminate non valueadding work. Time study is the study carried out to assess human effectiveness by improved planning and sound incentive scheme to its employees. It is employed in the assessment of human efforts in all its aspects to lead systematically to all the factors which ultimately affect efficiency and economy of the situation under study in realizing the objectives of bringing about improvements. The purpose of this article is to highlight the benefits of statistical techniques over the traditional methods employed in construction. The writer intends to explain, why time-motion studies need to be carried out to determine the productivity of the system under study; why waiting line models need to be applied to find out the most optimum solution or method which will give highest productivity. Further, the authors stress that vendors must be rated based on their past performance for punctuality, quality and reliability, and hence a Vendor Rating Index(V.R.I) should be given to vendors, which would help assessing them for present or future assignments. Vogel’s Approximation Method must be applied to a Transportation Matrix for finding Initial Basic Feasible Solution (IBFS).Subsequently method of multiplexes must be applied to the Transportation Matrix to balance between supply and demand and hence find out the optimal units that need to be supplied from a particular site to a particular destination, minimum cost of transportation is obtained.
Comparative study and decision making for a formwork technique to be adopted on a construction site in mumbai
(IJRET: International Journal of Research in Engineering and Technology, 2016-01) Kazi, Arbaz; Parkar, Fauwaz
To address the housing and transportation requirements of an exponentially increasing population, Indian construction industry has grown by leaps and bounds. Thus with the globalization of Indian economy & introduction of multinational companies in India for construction activities, it has become imperative to have precise & speedy construction projects. Conventional construction methods are not able to cope with the demand of infrastructural facilities with high degree of quality control & assurance. No doubt, conventional methods prove to be economical, but they fail in providing required number of dwellings in time; hence latest construction technologies by applying fast-track construction is the only remedy left to address this issue. Formwork is an important part of construction and it takes 25-30 % of total cost of construction. Thus with the use of new technologies in formwork, construction permits casting of larger elements in a single pour, which reduces time and labour requirement as compared to conventional methods. Thus, the various new systems have promised to achieve overall economy with faster as well as high quality construction. In this paper, an attempt is made to have a comparative study of established conventional formwork technology with a set of new formwork techniques, which are currently not used much in Indian construction industry; and hence suggest which method is superior for the construction project under consideration.
Comparing design-build and design-bid-build project- Case of residential projects
(Thakur College of Engineering, 2016-02-20) Kazi, Arbaz; Parkar, Fauwaz
Every construction project is unique in nature; it needs certain resources, viz. man, material, machinery, money, methodology, time etc. in addition to conducive environment required for its successful execution. To complete any construction project vis-a-vis planned objectives within the allotted budget and stipulated time is always a difficult task for the management. With the continuous decline in profit margins and greater competition in construction projects, construction contractors are finding ways of eliminating waste and increasing profit. Although numerous approaches have been developed to improve efficiency and effectiveness of construction processes, there still seems lack of proper research to predict the performance of a particular parameter based on other factors affecting the project. Here, an attempt has been made to correlate the resource utilization for both traditional as well as fast-track construction, which would ultimately help project stakeholders, decide the optimum use of available resources. The objectives of this paper is to conduct a questionnaire survey on construction projects executed with both traditional and fast-track approach and determine Karl-Pearson’s correlation co-efficient between two independent projects (one traditional and one fast-track) w.r.t optimum resource utilization. In essence, this crux of this exercise is to help project stakeholders predict the approach to be adopted for a particular project.

(AIKTC, 2017-05) Parkar, Fauwaz; Tungekar, Ruh-ul-Ameen (13CE62); Gupta, Sonu (13CE61); Ansari, Waseem (13DCE69); Khan, Rmaeeza (14DCE73)
Increase in emission of carbon dioxide due to different industrial and non-industrial activities are posing a severe threat to global atmosphere. Cement industry contributes significantly in emission of carbon dioxide gas during its production. On the other hand, industrial by-products such as GGBS, fly ash, etc. poses a serious waste disposal problems thus affecting the economy of the town or nation leading to global environmental impact. Geopolymer concrete is a solution to this problem. Geopolymer is a class of aluminosilicate binding material synthesized by thermal activation of solid aluminosilicate base material such as GGBS and fly ash. Geopolymer concrete is produced due to alkalination of materials rich in aluminium and silicon with an alkali solution, an aqueous solution of sodium hydroxide and sodium silicate. Alkali solution was varied in different molar concentration as 16 M, 18M, 20M and 22 M with hydroxide to silicate ratio of 2.5. Two different set of concrete specimens were casted which were viz. fly ash based only and GGBS together with fly ash in the proportion to 70:30. All the specimens were cured at 60 °C in oven and accelerated curing tank for 3 days and atmospheric curing in lab till 28th day. It was observed that, oven dried curing showed a slight higher strength than steam cured and it was a successful.
Experimental study on bendable concrete
(AIKTC, 2018-05) Parkar, Fauwaz; Kazi, Izhan(14CE20); Khot, Suhail(14CE36); Majid, Ramish(14CE37)
Reducing the brittle nature of concrete has opened a new world of possibilities to enhance the safety, durability and sustainability of the next generation of civil infrastructure. Tiny fibres partly account for its performance, and also the materials are designed for maximum flexibility, because of its long life, the Engineered Cement composites (ECC) is expected to cost less in the long run, as well. The ductile or bendable concrete is made of same ingredients as in regular concrete minus the coarse aggregate. It looks exactly like normal concrete, but under excessive strain, the ECC concrete allows, the specially coated network of fibre in the cement to slide within the cement, thus avoiding the inflexibility that causes brittleness and breakage. The key factor is that ECC is engineered, means in addition to reinforcing the concrete with micro scale fibers that act as ligaments to bond the concrete more tightly As this is a special type of concrete there are no defined codes for it and also it is rarely developed in India hence no Indian Codes can be found related to this, thus for these reasons the parameters needed are to be obtained using trial and error method. This project includes different sets of tests such as marsh-cone test, slump test, sieve analysis, compression test, split tensile test and flexure test. To get the perfect dosage of admixtures marsh-cone test if well known for giving reliable results, similarly sieve analysis gives us the optimum sizes and proportion of the fine aggregates to be used in the making of this concrete. To determine the best possible water-cement and sand-cement ratio compression test was practiced and also it gives us the compressive strength of the concrete specimen. Finally the flexural strength of the concrete is determined by performing the flexural test on the specimen / member. Later on all the data is analysed and future predictions for flexural strength corresponding to different intermediate depths are made in regards to the results obtained. Also the ECC is compared with conventional concrete with regard to its weight and cost parameters.

(AIKTC, 2019-05) Parkar, Fauwaz; Hasamnis, Rahul Sunil [16DCES66]; Sayyed, Firoj Khalil [16DCES83]; Asari, Zoheb Md. Nazim [16DCES60]; Mansoori, Juned Amjad Ali [16DCES72]
Construction sector is the largest source of greenhouse gas emission around the world. Across the world, people are using a huge amount of resources for construction. Due to the growing environmental problems, it has become a great matter of concern. These environmental issues arising due to construction activities give both an opportunity as well as responsibility for the construction research community to develop eco-friendly buildings. For these, design integrity is an important parameter to be included during the design, construction and operation phase of the building when it is in conceptual stage. Sustainable development can be achieved through Green Building construction, energy conservation through energy analysis & energy management, energy simulation, energy modeling of a building etc. Green Building Certification can be achieved through practicing various green building codes such as LEED, BEE etc. Sustainable development aims to reduce the ever-surmounting pressure of energy production in the country thereby saving raw resources and contributing towards the environmental well-being. This work entirely focuses on investigating the ill-effects of construction sector on environment, the various modern green remedies available to solve such problems. In this work, life cycle cost analysis for 25 years of a proposed hostel building is performed under three different criteria i.e. LCCA of normal traditional building, LLCA by replacing the conventional building envelope materials with advanced construction materials building envelope and lastly LLCA on the basis of best orientation of the building in order to optimize the use of day lighting. Along with the LCCA, Net Present Value is to be calculated for the two criteria by considering the discounted rate method for Payback period of 25years and suggest whether using advanced construction materials and green building principle would be economically viable for the hostel or not. The benefit-cost analysis for the hostel building is performed on the basis of energy saving in terms of electricity. The Electricity consumption for all the three cases is calculated with the help of a well known software called as eQUEST 3-65. This software is accepted and certified by Energy Conservation Buildings Codes of India. Basic rates of electricity and labour have been collected from Wholesale Price Index (WPI) and Consumer Price Index (CPI) for predicting the future rates.

The project deals with analysis, design, modelling and energy analysis of residential building (G+7) by using ETABS, Autodesk Revit and Microsoft excel software. Analysis and modelling is done on ETABS, energy analysis on Autodesk Revit and foundation design on excel. In ETABS, initially analysis of structure was performed based on load calculations, occupancy and expected life span. Then, after analysis of structure, the maximum shear forces and bending moments is computed. The structure is designed based on the shear force and bending moments. Analysis and design was done taking into account the requirements an standards recommended by IS codes (IS-456:2000, IS-1893:2002, IS-13920:1993). After the analysis and design of the building was successfully completed in ETABS, energy modelling and analysis was performed in AUTOdesk Revit. Modelling is done as per the requirements given by the drawings AutoCADD and then the energy simulations are performed in AUTOdesk Revit by varying different materials in the models. The results are compared and the most energy efficient materialsobtained from the simulations are suggested.

(AIKTC, 2016-05) Parkar, Fauwaz; Duduke, Wasif (12CE17); Jiwrak, Amir (11CE18); Shaikh, Md. Abrar (12CE52)
The purpose of this project is to investigate the behaviour of soil of our campus and to know its various parameters. For investigation, the soil sample was taken from the place where future construction is proposed. Sample collection was done using Excavator. The collected samples were classified as per IS classification system. The field moisture content of soil samples was determined using oven drying method and various other properties such as specific gravity etc. was determined. Optimum moisture content of the soil was determined using modified proctor test which was further used to determine other soil parameters such as CBR value, angle of internal friction, etc. Various soil parameters were obtained after performing laboratory experiments. Modelling of these soil parameters was done using XLSTAT software. Equations for various parameters are developed using multiple regression. Soil parameters for different depths were predicted using the models prepared.
System design for effective construction inventory management
(AIKTC, 2021) Parkar, Fauwaz; Kazi, Abdul Aziz Faroq (18CEM04)
Construction industry is the most crucial industry for any nation with respect to its economic growth and development. This industry is complex and hence susceptible to disputes, delays and cost overruns. As a thumb rule, in developing countries, it is estimated that construction materials alone account for more than 60 percent of the total expenditure of a project. Therefore, effective and efficient material management is paramount for successful completion of a construction project within the estimated budget and time. This study in the initial phase compares various available techniques of material/inventory management, such as ABC Analysis, Economic Ordering Quantity (EOQ), Material Requirements Planning (MRP), Just-In-Time (JIT) concept, etc., and their feasibility in the construction industry. Even after having a number of techniques developed for material/inventory management that are efficiently applied to other types of industries, it is observed that most of these techniques seem to have limitations in case of construction industry due to its complex and highly uncertain nature. The methods are applied to construction industry to some extent, but straightforward and holistic application is not feasible, i.e., impractical and perhaps impossible. This can be owed to the fact that each construction project is unique and construction processes are often demand driven. Work stoppages and sometimes crippled schedules due to overlapping of activities is a common phenomenon observed in construction. Therefore, a need is felt that a reliable system, flexible enough to take into account the changing inventory requirement pattern be devised, so that material wastage is avoided, as well as associated under-stocking and over-stocking costs are eliminated.

Use of statistical methods in construction industry
(International Conference on Civil, Structural and Environmental Engineering: ICSEE, 2011-02-18) Parkar, Fauwaz
While manufacturing industry has generally been capable to apply new concepts successfully, construction industry still appears failing to apply them. Although these two industries differ significantly from each other, there is no obvious reason why construction industry should not be able to take advantage applying new concepts, and reject its denounced traditionalism. The new trends have been represented by concepts like mathematical modeling, operations research, lean production techniques, total quality management and just-in-time production. This paper is thus intended to highlight the various scenarios in the life-cycle of construction projects, where statistical methods can be used to overcome the drawbacks of traditional construction. Time studies have been conducted on various grades of manpower and equipments in Indian construction to measure their actual productivity. The application of statistical methods in construction provides construction managers and other decision makers the opportunity of experiencing and responding to various factors which are responsible for loss of productivity, and hence eliminating them.
