Developing Forensic Investigation Standards to Effectively Deal with Structural Failures

Abstract: The human society has witnessed failures of many landmark structures right from that of tower of Babel to the collapse of Hotel Hyatt Regency walkway, U.S.A. Despite advancement of technology and improvements in the field of construction, failures are inevitable even today. Till recently, the failure of Kota Chambal Bridge created lot of panic to look for integrity and investigation of the conditions of all bridges by railways. All such failures raise curiosity of technologist as to why it happened. Man tries to obtain an answer and ultimately decide on liability. This arena where construction and law meet to investigate the cause of failure as well as determine liability is called forensic engineering. Literature suggests that forensic engineering is a quite widespread practice in the U.S.A whereas in India, not only there is lack of enough standards for investigation but also lesser practice of the same. Most often, failures in India are either police or insurance matters. It is therefore the object of this study to develop forensic investigation standards based on the time at which the failure occurs during building life cycle and how to minimize the socio-economic losses occurring consequentially. A questionnaire was circulated among more than 140 professionals in reputed firms in the construction and legal industry to gather information on how they/their organisation deal with failures, during what phase they occur, whether there are any legal implications and to what extent need is felt for a systematic approach to investigations of failures. Out of these 140 professionals, as many as 41 have responded to the query and contribute very important information. The questionnaire reveals that the industry feels there is a dire need for adopting forensic engineering and the only standards they rely on is non-destructive tests. A number of cases of failures in India and in U.S.A., which have occurred during construction and service period stages of life cycle of structure, were studied for their process, reports and laws of investigations. They have been evaluated for the socio-economic losses that occurred and the way how legal implications were dealt with by the parties or investigators involved. It is revealed so far that more often than not, an innocent professional is convicted without first investigating scientifically the cause. The game of blame shifting gets momentum. It is also found that depending on when the failure occurs during the building life cycle, the investigation process needs to be adapted accordingly. Finally, certain recommendations will be proposed for each phase, based on the differences between the process of investigation adopted in U.S.A and India.

Building Information Modelling (BIM) Based Sustainability Analysis for a Construction Project

Abstract: The Building Information Modelling (BIM) is transforming the way building delivered traditionally. The Construction industry is growing rapidly and the demand for Sustainable facilities with least impact on the Environment is increasing. Sustainable development has been divided into water conservation, energy use reduction, sustainable procurement of materials, industrial development, recycling, waste reduction, climate change, transport strategies, and biodiversity. Sustainable building is one that fulfills Social, Environmental and Economic concerns in a balance way. In this study, the sustainability analysis of a hotel building is performed with the help of Building Information Modelling (BIM). It covers various aspects such as considering building sun- path, location, orientation, heating and cooling loads thermal properties of materials, Ventilation and Daylighting analysis. A systemize methodology is adopted and tools like Autodesk Insight and Autodesk Green Building Studio has been used. The Social, Environment and Economical Impact were studied and it was noted that in building information modelling, sun-path analysis, Wind analysis, heating and cooling load analysis and shading/lighting analysis can be performed with ease, along with that it also helps in Predicting energy consumption and cost of the building Facility. The finding of the study suggest that the adaptation of BIM for sustainability analysis help in improving building performance, predicting performance throughout the lifecycle and reducing the consumption of resources. Further, Cost-Benefit Ratio (CBR), Investment grade audits can also be generated by adopting BIM technology in future.

Analytic Study of Construction Delays

Abstract: Construction is a commercial process which is very sensitive to changes and dependent on market parameters. It is because of these factors that changes are orders of the trade. Usually it is Time overrun that leads to Cost overrun because time is money; it is absolutely true in construction industry. The employer wants the construction to be completed as early as possible so that he can have the fruits of his investment and therefore he usually builds in a clause in contract suggesting time as essence of contract. In event of contractor failing to complete the work within the expected time, he would be liable to pay certain compensation which is designated as Liquidated damages. There is hardly a project which can be performed as planned and as envisaged. The projects are programmed to be performed. However due to number of Reasons, the project are confronted with unanticipated situations resulting in delay. The project requires changes to be resolved and time to be compensated. The one single cause of dispute in differences between the parties to a contract revolves around the issue of compensation arising out of and related to time. In other words, Delay Damage Analysis is at the center of search for efficient contract management. In fact the construction management to a large extent is How to Analyze Delay Damages. This study helps the construction manager to evaluate compensation for whatever the delays had occurred as also to evaluate the compensation to be recovered as and by way of liquidated damage. It is this study which provides the construction manager with data to grant extension of time as also to evaluate the extra amount payable by way of escalation. In short analysis of delay damages is at the core of estimation of compensation payable or recoverable from either of the parties to the contract. However by study of various projects of infrastructures, it is observed that hardly any project has achieved time and cost parameters. It is also revealed from the various case studies that majority of the projects landed in litigations and major cause was time over run and there by additional cost on the project. It is also observed that from study of cases and also by attending arbitration related to construction contracts that there is no systematic mechanism to monitor the delay caused on the project. Though project management system exists but is not scientifically developed to achieve the proper records of data and dates. During the research it is observed that in developed country they have scientific methodology to take care of Delay on completion of project and there by analyzing the same for the probable cost impact. This prompted to carry out research on this topic and develop or create awareness of use of any methodology which can reduce long and costly litigation.

Evaluation of energy use intensity (EUI) and energy cost of commercial building in India using BIM technology

Abstract: Large amount of energy is being consumed by the buildings at its operational phase and it is one of the significant source of carbon discharge throughout their service life, which directly affects global warming. Therefore, it is essential to optimize energy use intensity (EUI) as well as energy cost with the utilization of the building information modeling technology (BIM) to perform energy analysis. Objective of the study is to study modeling software for energy simulation and to evaluate different measures by altering design criteria’s and thereby reducing energy consumption for achieving best energy-efficient building in terms of EUI and energy cost. In this study, an attempt has been made to evaluate the EUI and energy cost of a commercial building located in Vadodara City, Gujarat, India. Modeling of the building is performed by utilizing Autodesk Revit Architecture, and further for energy analysis, Autodesk Insight is used. These study targets are to provide energy-efficient building by varying different design strategies with respect to EUI and energy cost based on ASHRAE 90.1 standards. It is observed that with the minor variation in design strategies causes large percentage of difference in the EUI as well as energy cost. Present work concludes from the energy analysis that energy cost can be reduced up to a great extent by implementing BIM which is helpful to implement better design options prior to construction of building by optimizing annual energy budget incurred compared to traditional methods which may involve errors in computations.

Beyond Failure : New Essays on the Cultural History of Failure in Theatre and Performance

Abstract: In setting foot on stage, every performer risks the possiblity of failure. Indeed, the very performance of any human action is inextricable from its potential not to succeed. This inherent potential has become a key critical trope in contemporary theatre, performance studies, and scholarship around visual cultures. Beyond Failure explores what it means for our understanding not just of theatrical practice but of human social and cultural activity more broadly. The essays in this volume tackle contemporary debates around the theory and poetics of failure, suggesting that in the absence of success can be found a defiance and hopefulness that points to new ways of knowing and being in the world. Beyond Failure offers a unique and engaging approach for students and practitioners interested not only in the impact of failure on the stage, but what it means for wider social and cultural debates.
