the rosewood experiment building Information Modeling and interoperability for architectural precast facades
Automation in Construction, 2010Co-Authors: Rafael Sacks, Charles M Eastman, Israel Kaner, Y S JeongAbstract:Abstract The Rosewood experiment examined building Information Modeling (BIM) and product data exchange in the design and fabrication of architectural precast facades. The facade panels of a 16 story office building were designed and fabricated using traditional CAD, while a parallel workflow was performed independently using BIM tools. No limitations were encountered in designing and detailing of precast facade pieces with current software. Production of the same set of drawings showed a productivity gain of 57% over the CAD process. However, the data exchanges between architectural and precast engineering systems were incomplete and inconsistent, confirming the need for BIM exchange standards. The existing Industry Foundation Classes schema (IFC version 2x3) lacks precast-specific entities and property sets. The majority of the difficulties can be traced to a loss in translation of semantic meaning for the objects exchanged.

unique requirements of building Information Modeling for cast in place reinforced concrete
ASCE International Workshop on Computing in Civil Engineering 2007, 2007Co-Authors: Ronen Barak, Rafael Sacks, Yeonsuk Jeong, Charles M EastmanAbstract:The building Information Modeling (BIM) tools that have matured for structural steel and precast concrete construction are not suitable for production Modeling of cast-in-place (CIP) reinforced concrete structures. The main reason is that CIP structures are monolithic in nature, as opposed to the discrete objects that are typical of steel and precast. A consortium of 12 major contractors and design firms collaborated over a one-year period to formulate the functional requirements for development of a BIM tool for cast-in-place reinforced concrete. The functional requirements were derived from a process model used to scope and understand the processes surrounding reinforced concrete design and production. The functional requirements were finally expressed as a set of object schemas, defining relations, methods, and attributes needed. These are essential for software companies to incorporate in their BIM tools to provide for the unique needs of Modeling CIP structures.

specifying parametric building object behavior bob for a building Information Modeling system
Automation in Construction, 2006Co-Authors: Rafael Sacks, Charles M EastmanAbstract:Parametric Modeling has been proposed as an effective means to embed domain expertise in models of buildings. As Information technology becomes more powerful in terms of the ability to manipulate large parametric models, the potential grows to build increasingly sophisticated functional systems for designing, Modeling and fabricating buildings. Implementing more powerful systems implies greater functional specificity, which requires elicitation and capture of increasingly detailed and complex domain-specific semantics and knowledge. This paper explores the extent to which design and engineering knowledge can be practically embedded in production software for building Information Modeling (BIM). It focuses on a building object behavior (BOB) description notation and method, developed as a shorthand protocol for designing, validating and sharing the design intent of parametric objects. Examples are drawn from an advanced BIM system development project for precast concrete.

semantic enrichment for building Information Modeling
Computer-aided Civil and Infrastructure Engineering, 2016Co-Authors: Michael Belsky, Rafael Sacks, Ioannis BrilakisAbstract:Significant difficulties remain in exchanging Information between building Information Modeling BIM tools. The industry foundation classes IFC exchange schema is too generic to capture the full semantic meaning needed for direct use by different construction project stakeholders' BIM tools. Although BIM standards that prescribe model view definitions MVD for domain-specific exchanges are under development, insufficient semantic definition of exchanges prevents achievement of the full potential of BIM through seamless interoperability. We propose an innovative approach for supplementing an IFC exchange file with semantically useful concepts inferred from the explicit and implicit Information contained in the building model. A prototype software was implemented to test the applicability of the approach. It consists of a rule-processing engine and allows composition of inference rule-sets that can be tailored for different domains. The tests demonstrate semantic enrichment with precast concrete building models, adding inferred joint, slab aggregation and connection concepts.

interaction of lean and building Information Modeling in construction
Journal of Construction Engineering and Management-asce, 2010Co-Authors: Rafael Sacks, Bhargav Dave, Robert OwenAbstract:Lean construction and Building Information Modeling are quite different initiatives, but both are having profound impacts on the construction industry. A rigorous analysis of the myriad specific interactions between them indicates that a synergy exists which, if properly understood in theoretical terms, can be exploited to improve construction processes beyond the degree to which it might be improved by application of either of these paradigms independently. Using a matrix that juxtaposes BIM functionalities with prescriptive lean construction principles, fifty-six interactions have been identified, all but four of which represent constructive interaction. Although evidence for the majority of these has been found, the matrix is not considered complete, but rather a framework for research to explore the degree of validity of the interactions. Construction executives, managers, designers and developers of IT systems for construction can also benefit from the framework as an aid to recognizing the potential synergies when planning their lean and BIM adoption strategies.

teaching building Information Modeling as an integral part of freshman year civil engineering education
Journal of Professional Issues in Engineering Education and Practice, 2010Co-Authors: Rafael Sacks, Ronen BarakAbstract:Lack of personnel with Building Information Modeling BIM skills is a significant constraint retarding use of the technology in the architecture, engineering, and construction industry. Unless BIM is introduced into undergraduate civil engineering curricula in a fundamental way, graduate civil engineers will lack the skills needed to serve a construction industry in which three-dimensional models are the main medium for expression and communication of design intent and the basis for engineering analysis. A mandatory freshman year course titled "Communicating Engineering Information," which teaches both theoretical and practical aspects of BIM, has been developed to replace the traditional engineering graphics course at the Technion. The main lesson learned through four semesters of teaching the class is that students find BIM tools intuitive and therefore relatively easy to learn; the majority of lecture hours are now devoted to the conceptual aspects of BIM and the principles for preparing models that can be analyzed in multiple ways. BIM can and should be taught in its own right, and not as an extension to computer-aided drawing. The skills students have been able to bring to bear in design courses later in their university education indicate that the approach is sound and will enable graduates to meet the needs of the civil engineering profession in the "BIM age."

building Information Modeling for nonresidential construction an industry perspective
DEStech Transactions on Computer Science and Engineering, 2018Co-Authors: Matthew Cash, Endong Wang, Xiaoni WangAbstract:More than traditional computer-aided design (CAD), Building Information Modeling (BIM) can include a lot of additional Information about the various products and systems in the design. It was noticed that BIM had unbalanced applications among different types of construction. BIM has been shown to provide a significant cost savings to the design firms and clients by its use in residential construction. Yet, it has limited use on a very small number of industrial construction projects. Rather than performing a theoretical cost analysis on BIM usage to prove that it could save project cost, this paper explores the specific benefits that BIM provides from an industry perspective, and see how they would translate to the industrial construction sector. To do this, BIM users in industrial and commercial construction are surveyed. The first-hand survey results revealed that the two biggest benefits to BIM are clash detection and the large amount of Information it can provide to the entire stakeholder in the project. Comparing these benefits to the current practices used in the industrial engineering and construction field leads to the conclusion that, BIM usage is probably not worth the cost investment for these firms. There are some additional considerations as to why including BIM capabilities in a company’s profile would be a good option, but cost savings is not the most important.

Building Information Modeling based building design optimization for sustainability
Energy and Buildings, 2015Co-Authors: Sha Liu, Xianhai Meng, Chiming TamAbstract:Environmental problems, especially climate change, have become a serious global issue waiting for people to solve. In the construction industry, the concept of sustainable building is developing to reduce greenhouse gas emissions. In this study, a building Information Modeling (BIM) based building design optimization method is proposed to facilitate designers to optimize their designs and improve buildings' sustainability. A revised particle swarm optimization (PSO) algorithm is applied to search for the trade-off between life cycle costs (LCC) and life cycle carbon emissions (LCCE) of building designs. In order to validate the effectiveness and efficiency of this method, a case study of an office building is conducted in Hong Kong. The result of the case study shows that this method can enlarge the searching space for optimal design solutions and shorten the processing time for optimal design results, which is really helpful for designers to deliver an economic and environmental-friendly design scheme.

a benefits realization management building Information Modeling framework for asset owners
Automation in Construction, 2014Co-Authors: Peter E D Love, Jane Matthews, Andrew Hill, Ian Simpson, Oluwole A. OlatunjiAbstract:Abstract An asset owner's decision to implement Building Information Modeling (BIM) can enable strategic business outcomes. For an asset owner the implementation of BIM should not be seen as a discrete Information technology project, but a business change program that can potentially impact their ‘value proposition’. Benefits realization recognizes that technology alone cannot deliver business outcomes and that the process of its implementation is proactively managed to ensure that the organization obtains the results it expects. This paper presents a novel framework that asset owners can use to ensure that they can obtain ‘value’ from investing in BIM. It is proffered that the benefits realization process should be viewed as a learning process that enables the asset owner to constantly question and measure the benefits of BIM.

from justification to evaluation building Information Modeling for asset owners
Automation in Construction, 2013Co-Authors: Peter E D Love, Andrew Hill, Ian Simpson, Craig StandingAbstract:Abstract Building Information Modeling (BIM) is an emerging technology focused methodology that can be used to improve the performance and productivity of an asset's design, construction, operation and maintenance process. Typically the investment justification process for BIM has been based upon the utilization of the return on investment (ROI). This measure does not accurately reflect the ‘real’ costs and benefits that are associated with implementing BIM by an asset owner. With this in mind, a benefits evaluation framework that looks beyond ROI and takes into account the evolving nature of BIM by incorporating intangible benefits and indirect costs is presented and discussed. To acquire the wide range of benefits that BIM can offer asset owners, it is proffered that they should shift their mindsets away from justification using ROI to a process of evaluation that encompasses the appraisal of value and benefits' realization.

a conceptual framework for integrating building Information Modeling with augmented reality
Automation in Construction, 2013Co-Authors: Xiangyu Wang, Peter E D Love, Chan Sik Park, Chun Pong SingAbstract:During the last two decades, designers have been embracing building Information Modeling (BIM) to improve the quality of the documentation that is produced as well as constructability. While BIM has become an innate feature of the design process within the construction industry, there have been limited investigations that have examined how it can be integrated into real-time communication on-site. In addressing this gap, this paper proposes a conceptual framework that integrates BIM with augmented reality (AR) so as to enable the physical context of each construction activity or task to be visualized in real-time. To be effective, it is suggested that AR should be ubiquitous (including context awareness) and thus operate in conjunction with tracking and sensing technologies such as radio frequency identification (RFID), laser pointing, sensors and motion tracking.

Design error reduction: toward the effective utilization of building Information Modeling
Research in Engineering Design, 2011Co-Authors: Peter E D Love, Sangwon Han, David J. Edwards, Yang M. GohAbstract:An advocated panacea for reducing design errors and rework in construction and engineering projects is building Information Modeling (BIM). Yet, it would appear that advocates of BIM have overlooked why and how design errors occur. In this article, the nature of error is explained and the principal underlying causes identified with reference to the normative literature and the authors phenomenological research. A systemic model for reducing design errors is presented and the enabling role of BIM discussed.
