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.

Earn Value Management a Boon to Indian Construction Industry
(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 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.
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.

Quality improvement by using quality control indicators in high rise building
(International Advanced Research Journal in Science, Engineering and Technology, 2018-02) Shaikh, Mohammed Ayyaz Mohammed Qasim (15CEM13); Magar, Rajendra; Mahajan, Girish
Three important parameters such as time, cost and quality are essentially necessary for successful completion of construction projects. Quality is the real parameter that is responsible for safety and overall health of construction projects. Maximum defect occurs during execution phase only due to non-compliance of desired specifications. It is observed that, on many sites, executors are not aware about quality control checklist and its significance. This is the reason why defects occur in even newly constructed structures. To overcome this, Android application, have been developed for Quality Control Indicator by using the Six-sigma process. The Six Sigma processes that are generally used in manufacturing plants, however its implementation has started in the construction industry. In the Android application, quality control checklist prepared by a construction company had taken for reference. Project authorities can apply quality control checklist on the activities and can give their remarks about the performance of particular construction activity such as Satisfactory (S ), Unsatisfactory (US ) and Not Available (NA). If any defect occurs in the activity and if it is not mitigated by site engineer or supervisor then the higher authority may take appropriate corrective action. By using this, Quality Control Indicator Application time required for lengthy conventional quality control process can be considerably reduced. Through this application, six sigma levels for particular performance are obtained immediately as well as cause s and effects of particular defect is also recorded in the application. Hence, this study covers the entire process of quality control indicators and android application for obtaining six sigma levels of various activities of the project. This study focusses on use to quality control indicator for various construction activities. QC Indicators indicates the quality status of the activity for facilitating the application of remedial measures in order to improve quality.
Resource optimization for sustainable construction: A state of art
(International Advanced Research Journal in Science, Engineering and Technology, 2018-02-03) Tiwari, Shivendra (16CEM13); Magar, Rajendra; Honnutagi, Abdul Razak
The estimated cost of construction material on any construction project is about 40-60% of the total construction project cost in which approximately construction material’s waste contributes 30-35% of the material cost, which in result leads to project cost overrun and loss of materials. Lesser studies have been done for the construction material waste reduction or optimization directly at the time of its use on site. The basic aim of this study is to describe the methods by which the construction material as a resource can be used sustainably reducing the wastages and prevention at site during construction. The study discloses that selection of less experienced working method and the poor quality of materials to be used on site also results in material wastage during sudden design stage. The major beginning of material wastages during construction stage are improper uses of material as well as labors. Similarly, while procurement, wastages are caused during loading, unloading and transportation processes and unavailability to order small quantities of material. Also, lack of knowledge and improper security for materials procured causes the same even before its use on site. Thus, the study can be used further in co-ordination of optimization techniques on site to reduce the wastages and cost of materials during construction.
Review on simulating uncertainties in construction projects
(International Advanced Research Journal in Science, Engineering and Technology, 2018-02) Katrekar, Shweta Sushil (16CEM06); Magar, Rajendra; Khan, Afroz
Uncertainty certainly affects the performance of a construction project. The exact definition of risk and uncertainty is still not known. Everyone has their own perspectives. Though, it is accepted as the results and outcomes are likely to differ from expected values. The values can be considered to be Time, Quality and Economy of the project depending upon the project needs. Therefore, in construction project management, the effects of unidentified risks and uncertainties hamper the project time, quality as well as its economy and ultimately obstruct the project management and thus its development. Identifying the uncertainty and quantitatively analyses the impact on the project performance can notably enhance the exactness, validity and reliability of a project plan. This paper describes a methodology to systemize, model, and diminish uncertainty. Uncertainty management is one of the major problems faced in construction. Most of the solutions aim to solve the problem but it has to meet demands of all project criteria. The uncertainty is always evaluated at the start of the construction project but it should be continuing process with solutions at the time of whole project life cycle. The application of risks and uncertainties management is practiced in construction in developing countries and thus the result poses massive challenges in the project development and management. Therefore, this study provides a brief idea of various research taken place to simulate the identified uncertainties in construction projects. It also recommends the idea of uncertainty and risk and their consequences on construction projects management as one of the challenges faced in the construction industry of developing countries.

Review on weibull analysis for performance evaluation in construction project
(International Advanced Research Journal in Science, Engineering and Technology, 2018-02) Gavaskar, Pradnya (16CEM05); Magar, Rajendra; Honnutagi, Abdul Razak
In construction projects, construction project managers monitor and control the project performance to ensure the project is under control. The Earned Value Management (EVM) method is a tool that integrates three critical elements of project management: scope management, cost management, time management. EVM is traditi onally used to monitor and control the project performance by using cost and schedule indices. EVM is widely used to forecast project cost and time at completion. However, the application of EVM is limited due to poor accuracy in forecasting cost and sched ule performance. Conventional EVM has inability to address the uncertainties as well as their causes and effects. Recently, many EVM - based cost and schedule performance forecasting methods were introduced by many researchers. This study describes the major aspects of EVM and useful statistical techniques to enhance the effective application of EVM in project management. Further it includes the overview of a statistical approach to refine and improve the performance of conventional EVM by introduction of Wei bull Analysis. This can be used in addition with EVM to give probabilistic approach to evaluate cost and schedule performance in construction project
Use of Rice Husk Ash in Concrete
(International Journal of Scientific and Engineering Research, 2015-12) Syed, Mehdi Abbas (14CEM16); Patil, Dada S.
This paper summarizes the research work on the properties of Rice Husk Ash (RHA) when used as partial replacement for Ordinary Portland Cement (OPC) in concrete. OPC was replaced with RHA by weight at 5%, 10% and 15%. 0% replacement served as the control. Compressive Strength test was carried out on hardened 150mm concrete cubes after at1, 3, 7, 28, 45 & 56 days curing in water. The results revealed that the Compacting factor decreased as the percentage replacement of OPC with RHA increased. The compressive strength of the hardened concrete also decreased with increasing OPC replacement with RHA. It is recommended that further studies be carried out to gather more facts about the suitability of partial replacement of OPC with RHA in concrete.
Valuation of residential properties by hedonic pricing method (HPM)
(International Journal of Engineering Development and Research, 2016) Kanojia, Anita (14CEM04); Magar, Rajendra; Jadhav, Umesh
Hedonic Pricing Method (HPM) is used for estimating the value of a commodity or the demand for a commodity. The method has been widely used in real estate and housing market research in the recent past. In this report, Estimation of residential market price by Hedonic Pricing Method due to environmental service is discussed. Environmental services is a concept from the ecological economics literature. 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.” It undertake an examination of use of this methodology in the recent real estate and housing literature in the preparation of housing predictive model. The idea behind the HRM is that the commodities are characterized by their constitute properties, hence the value of a commodity can be calculated by adding up the estimated values of its separate properties. Data required that influences the residential property rates will be collect.ed and are analysed 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.
Valuation of Residential Properties by Hedonic Pricing Method- A State of Art
(Institute for Research and Development, India, 2016) Kanojia, Anita (14CEM04); Jadhav, Umesh
The Hedonic Pricing Method (HPM), also known as hedonic Regression method (HRM) and Hedonic Demand Method (HDM) is used in estimating the value of attributes or the demand of attributes. Hedonic goods are analyzed by "Hedonic price model" and it makes possible to calculate the suitability of price indices in the commodity markets. Hedonic attributes involve immovable properties, such as apartment, computers, cars, home things, mobile phones etc. The features of these goods form their prices. Marginal effects of features of attributes in forming the prices of hedonic goods can be determined by this approach. In other words, the parameters obtained from estimating the hedonic price model describes the marginal value of characteristics of goods. The HPM has been widely used in real estate and housing market research in the recent past. The idea behind the HPM is that the commodities are characterized by their constitute properties, hence the value of a commodity can be calculated by adding up the estimated values of its separate properties. In this paper, emphasis is given on case study related to applicability of hedonic Pricing method, its methodology, comparison with other methods and its limitations.
