Review on simulating uncertainties in construction projects
(International Advanced Research Journal in Science, Engineering and Technology, 2018-02) Katrekar, Shweta (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.

(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.

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.
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
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.
Experimental Investigation and Prediction of Compressive Strength of HPC with SCMs
(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
Prediction of unconfined compressive and Brazilian tensile strength of fiber reinforced cement stabilized fly ash mixes using multiple linear regression and artificial neural network
(Advances in Computational Design, Vol. 2, No. 3 (2017) 225-240., 2017) Magar, Rajendra
This paper presents the application of multiple linear regression (MLR) and artificial neural network (ANN) techniques for developing the models to predict the unconfined compressive strength (UCS) and Brazilian tensile strength (BTS) of the fiber reinforced cement stabilized fly ash mixes. UCS and BTS is a highly nonlinear function of its constituents, thereby, making its modeling and prediction a difficult task. To establish relationship between the independent and dependent variables, a computational technique like ANN is employed which provides an efficient and easy approach to model the complex and nonlinear relationship. The data generated in the laboratory through systematic experimental programme for evaluating UCS and BTS of fiber reinforced cement fly ash mixes with respect to 7, 14 and 28 days‟ curing is used for development of the MLR and ANN model. The data used in the models is arranged in the format of four input parameters that cover the contents of cement and fibers along with maximum dry density (MDD) and optimum moisture contents (OMC), respectively and one dependent variable as unconfined compressive as well as Brazilian tensile strength. ANN models are trained and tested for various combinations of input and output data sets. Performance of networks is checked with the statistical error criteria of correlation coefficient (R), mean square error (MSE) and mean absolute error (MAE). It is observed that the ANN model predicts both, the unconfined compressive and Brazilian tensile, strength quite well in the form of R, RMSE and MAE. This study shows that as an alternative to classical modeling techniques, ANN approach can be used accurately for predicting the unconfined compressive strength and Brazilian tensile strength of fiber reinforced cement stabilized fly ash mixes. Keywords: artificial neural network (ANN); back propagation algorithm; multiple linear regression (MLR); fly ash; unconfined compressive strength (UCS); Brazilian tensile strength (BTS)

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.

(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.

Prediction of Blast Loading and Remedial Measures on Buildings
(International Conference On “Emerging Trends in Technology and it’s Applications”, 2014) Maralapalle, Vedprakash
Events of the last ten years have greatly heightened the awareness of building owners and designers of the threat of terrorist attacks using explosives. Blast loads become important service loads for certain categories of structures. An important task in blast-resistant design is to make a realistic prediction of the blast pressures. The distance of explosion from the structure is an important datum, governing the magnitude and duration of the blast loads. The current practice is to choose some arbitrary distance for design purposes. This paper presents some results of analytical studies to show that such a notion is likely to be erroneous, particularly for tall and slender structures. The elements of the blast phenomenon are reviewed, before going into the formulations leading to the ‘critical blast distance’ at which the transient dynamic response rises to a maximum. It also contains Treatment provided to various part of a structure to improve blast resisting mechanism and Architectural aspect of blast resistant buildings design.
