(International Journal of Business Excellence - Inderscience, 2016-04) Honnutagi, Abdul Razak
As the Indian industry becomes globally competitive in several sectors, one of the critical factors is the success of the engineering and technical education. The objective of this paper is to present a research study initiated for developing an integrated framework for quality excellence in engineering education. About 20 quality excellence models and international quality awards were studied in depth and it was found that almost all models lack predictive ability. In order to incorporate predictive ability of the quality excellence models, system dynamics methodology was used in the study. The system dynamics model thus developed for predicting quality excellence was used to generate various scenarios and analysed. which are presented in this paper.

Application of Principles of lean management in Construction Industry, A technique in the Indian construction industry
(International Journal of Recent Advances in Engineering & Technology (IJRAET), 2016) Pillai, Karuna; Shukla, Manojkumar; Magar, Rajendra
The construction industry has been severely vexed by several problems, and one of the major attributors being ‘the construction waste’. There is a severe need for identifying the sources of wastes and to improve the competence and to cut back on these wastes. For this Lean construction and its tools have been introduced as a new management principle for better implementation. These include reducing variability in production and production cycles. The tools that shall be used to achieve this include following a push-pull approach, use of multifunctional, multi skilled teams, and scrutiny of the following by just in time schedules. There are countless challenges in the implementation of lean concept in construction industry. The implementation of lean management in Indian construction industry is scarce. Due to lack of attention and illiteracy towards the lean management principles and application of its tools the owner, contractor, engineers etc. are still acquiring training to implement this principle in their projects. This project mainly focuses on to identify the possibilities of implementation of lean management in construction industry. It will be achieved by preparing the questionnaire and also conducting the interview with the project personals like top management, engineers and site supervisors etc., via cyber mass media. The questionnaires shall then be evaluated to adopt the best suited techniques through statistical methods. This paper focuses on the possibilities of effective utilization of lean management principles in construction industry, which can surely increase the quality of work and profit rate by eliminating the wastage of material.
Artificial Intelligent Techniques in Rainfall-Runoff Process
(5 International Conference on Water Resources and Arid Environments (ICWRAE 5), 2013-01-07) Magar, Rajendra
The use of rainfall-runoff (R-R) models in the decision making process of water resources planning and management has become increasingly indispensable. R-R modeling is still one of the most difficult issues in hydrological sciences due to the dynamic, uncertain and non-linear characteristics and relationship among the processes. In the broad sense R-R modeling has started at the end of 19th century and till today various types of models have been developed and applied based on their mechanism, input data and other modeling requirements. Fairly a large number of empirical, conceptual and physically based models having their own merits and demerits have been developed and applied to map the R-R relationship. In the real world, temporal variations in data do not exhibit simple regularities and thus R-R process is difficult to analyze and model accurately by conventional modeling approach. Hence R-R modeling approach has been shifted from process based technique to data-driven based Artificial Intelligent (AI) techniques like Artificial Neural Network (ANN), Adaptive Neuro Fuzzy Inference System (ANFIS), Genetic Programming (GP) and Model Tree (MT). The primary aim of this paper is to highlight the merits and demerits of those recent works on R-R modeling using AI techniques. As a value addition, a graphical user interface (GUI) has been developed as a decision support system.
building information modeling (BIM) application in Architecture, Engineering and Construction (AEC) Industry
(International Journal of Recent Advances in Engineering & Technology, 2016) Pakhmore, Mudassir Zahid; Mansoori, Raiyan; Gawade, Prathamesh P.
Abstract— The Architecture, Engineering & Construction (AEC) industry has a long chase to overcome the barriers of conventional method come from project cost overrun, poor productivity, quality, and extended time. Building Information Modeling (BIM) offers the traditional approach to overcome these drawbacks in a highly integrated fashion with efficient and effective collaboration between all stakeholders. As a result, it has been acknowledged as one of the rising trends in the contemporary construction industry. However the use of BIM has not been limited only in the building construction industry, also rapidly growing for almost all type, scale and size of built environment projects. It has now exhibits promising trends to all other construction works such as bridge, roads, power plants, industry facility and so on. BIM is Single file concept ollaborating various database of the project at one platform. It is a data repository for building design, construction & maintenance information combined in one convenient model to share with all the stakeholders. 3D visualizations allow customers to see historic preservation & site context with respect to the new project. This paper highlights perspective of a planning engineer with respect to Conventional method & BIM and gives a methodology to prepare a 4D simulated model of a Gr. (Stilt) + 16th Floor residential building taking 4th dimension as time. Furthermore it includes case study references to exploit the rational findings of BIM.
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.

(Tech-Chronicle, 2016-09) Magar, Rajendra; Shukla, Manojkumar
Earned Value Management (EVM) is a systematic approach to the integration and measurement of cost, schedule, and technical (scope) accomplishments on a project or task. It provides both the government and contractors the ability to examine detailed schedule information, critical program and technical milestones, and cost data. .EVM technique can do forecasting of duration for a project .It gives a well-defined pathway of existence to the project and when to take precautionary measures for updating the project if project is behind the schedule. It can be used to identify the cost overruns and time overruns. EVM technique can be applied using certain software's like MSP, Primavera, etc.
Effect of Colloidal Nanosilica on High Strength Rice Husk
(Journals Pub, 2017-01) Magar, Rajendra; Khan, Afroz; Gupta, Vipin (16DME138); Gupta, Vinay; Sayyed, Firoz Khalil (16DCES83)
Nowadays, supplementary cementitious materials (SCMs) are used in concrete because it reduces CO2 emission during. The husks, which are production of cement, reduces cement contents, improve workability, increase strength and enhance durability. Pozzolanic reaction takes place when siliceous or aluminous material comes in contact with calcium hydroxide in the presence of moisture to form compounds possessing cementitious properties approximately 50 percent cellulose, 30 percent lignin and 20 percent silica, are incinerated by controlled combustion leaving behind an ash that predominantly consists of amorphous silica. Rice husk ash is highly pozzolanic due to its extremely high surface area (50,000 to 100,000 m2/kg). The colloidal nano silica (CNS) which is nano material and behaved not only as a filler to improve cement micro-structure (porosity decrease), but also as a promoter of pozzolanic reaction used in cement for accelerating pozzolanic action due to which the cement sets faster than conventional mix. In the present study, the mineral admixture, rice husk ash (RHA) was used as 5, 10, 15% replacement for OPC in M60 grade of concrete. The 10% RHA was taken as optimum dose on the basis of workability and compressive strength. To this 10% RHA concrete, effect of 1, 2, 4, and 6% CNS addition were experimentally studied with various properties like workability, compressive strength and split tensile strength.
Effect of Environmental Service by Hedonic Pricing Model
(International Journal of Engineering Research, 2016-01) Kanojia, Anita (14CEM04); Jadhav, Umesh
Environmental services refer to qualitative functions of natural non-produced assets of land, water and air (including related ecosystem) and their biota, which implies natural environment providing particular important uses or benefits that can be captured under the concept of “services.” Our objective is to analyze the benefits associated with such environmental services in order to make them more visible. The hedonic pricing method uses the value of a surrogate good or service to measure the implicit price of a non-market good. The basic idea of the hedonic pricing method is that the price of a market good is related to its characteristics or the services it provides rather than the good itself. This article focuses on assessing residential property rate influenced by environmental services by applying hedonic pricing model. It is most commonly applied to variations in housing prices that reflect the value of local environmental attributes. The paper defines Hedonic Pricing method (HPM) and its methodology. Data required that influences the residential property rates will be collected and are analyzed using regression analysis which relates to statistically estimate a function that relates property values to the property characteristics, including the distance to open space. Thus, the effects of different characteristics on price can be estimated. The results can be used to evaluate the variations of property rates for small change in characteristics holding all other characteristics constant. Price prediction model is than prepared.
Estimation of Discharge Using LS-SVM and Model Trees
(Journal of Water Resources and Ocean Science, 2016-11) Magar, Rajendra
In planning and management of any water resource systems prediction or estimation of runoff over the catchment is considered as a crucial factor. Many researchers over the past two decades addressed these problems by traditional methods as well as with some new techniques. This paper is describable and is focused on the capability of some data driven techniques such as Least Square Support Vector Machines (LS-SVM) and Model Trees with M5 algorithm. These methods were used to estimate runoff of various stations in the catchment area in Upper Krishna basin, Maharashtra State, India, and discussed here two stations namely Shigaon and Gudhe. The specialty of these catchment areas is Shigaon has large area and Gudhe has small area. This was done to see the model performance in both conditions. Additionally metrological data was used in the process to see the performance of models. The quantitative analysis was carried out to check the performance of the accuracy by considering standard statistical performance evaluation metrics and the scatter plots are drawn for evaluating qualitative performances of the developed models. The effect of the various metrological parameters as an input parameter for the rainfall was also investigated.The performance of both the tools was judged with various performance measures and it is found that the results are quite encouraging. LS-SVM models performed better since it has captured all the higher peak discharges for both catchments, indicating LS-SVM is best suited for large sized catchments and MT tool is best suited for the smaller sized catchments. However LS-SVM performance is better as compared to MT as modeling approaches are examined, using the long-term observations of yearly river flow discharges.
Estimation of some meteorological parameters using hard and soft computing tools
(International Journal of Recent Advances in Engineering & Technology (IJRAET), 2016) Magar, Rajendra
Study of meteorological parameters is essential in deciding the effect on each other while finding out the best possible solution and the estimations for hydrological and meteorological parameters. The study involves in correlating all the measured parameters at Shivade catchment area of Narmada basin. The correlation on the observed parameters is carried out to perform overall sensitivity analysis. Out of al metrological parameters two of them are analyzed in this paper namely Dry bulb temperature and wet bulb temperature. The Dry Bulb and Wet Bulb Temperatures are important to determine the state of humid air. The knowledge of only two of these values is enough to determine the state including the content of water vapour and the sensible and latent energy. The meteorological parameters have been estimated using Multiple linear regression and artificial neural network (ANN). The meteorological parameters collected from Shivade catchment area. The data extended over a period from January 2002 to December2010 including only the monsoon months. Amongst the two methods, the ANN model exhibited better estimation values of the meteorological parameters.

(Journal of Advance Research Construction and Urban Architecture, 2017) Magar, Rajendra; Khan, Afroz Rahat Naeem; Khan, Rahil; Ansari, Shahbaz; Khan, Haroon
Due to environmental concern, the use of supplementary cementitious materials (SCMs) is increasing at a high rate in construction industry. In this study, an experimental investigation has been carried out to assess the compressive strength of high performance ternary mix concrete with judicious replacement of cement with (SCMs), which include industrial waste products such as fly ash (FA), ground granulated blast furnace slag (GGBS) and micro silica. Replacement of cement was done up to 40%, 45%, 50%, by incorporating P100 fly ash as an ultrafine material with GGBS as SCMs. Each replacement was further divided into three sub parts (40%F. A-60%GGBS), (45%F.A-55%GGBS) and (50%FA-50%GGBS). Experimental results showed that Mix T3 (60%Cement-20%F.A-20%GGBS) produced maximum strength of 89.4 MPa and 100 MPa at 14 days’ and 28 days’ curing respectively. Experimentally generated data in the laboratory was used for the development of the multiple linear regression models. Keywords: Cement; P100 fly ash; FA; GGBS; HPC; Compressive Strength
Experimental Investigation on Behavior of Piled- Raft Foundation
(International Journal for Science and Advance Research In Technology, 2017-06) Maralapalle, Vedprakash; Dasgupta, Rohan; Shaikh, Wasim (14CEM14)
Abstract-In the piled-raft foundation systems the load is assumed to be shared between the piles and raft. Therefore, this improves the ultimate load capacity and reduces settlements in a very economic way as compared with the traditional foundation concepts. The use of strategically located piles improves the load capacity of raft and reduces the differential settlement. This research sheds some light on the philosophy of using piles as settlement reducer for raft foundation and also the behavior of pile length and alignment on the attained ultimate load are experimentally investigated. The experimental program includes the model test on unpiled raft, raft supported by single pile, (2x2), (3x3) and (4x4) pile groups. From the accomplished studies, it has been concluded that as the number of piles underneath the raft increases, load carrying capacity of foundation increases. Also, there is a negligible effect on load improvement ratio and settlement reduction ratio with increase in raft thickness and number of piles. The observed settlement values from Experimental study was compared with numerical modeling using PLAXIS-3D and found the results are in good agreement. Keywords- Piled-Raft, PLAXIS-3D, Ultimate Load, Foundation.
