Discover BIM: A better way to build better buildings Building Information Modeling (BIM) offers a novel approach to design, construction, and facility management in which a digital representation of the building product and process is used to facilitate the exchange and interoperability of information in digital format. BIM is beginning to change the way buildings look, the way they function, and the ways in which they are designed and built. The BIM Handbook, Third Edition provides an in-depth understanding of BIM technologies, the business and organizational issues associated with its implementation, and the profound advantages that effective use of BIM can provide to all members of a project team. Updates to this edition include: * Information on the ways in which professionals should use BIM to gain maximum value * New topics such as collaborative working, national and major construction clients, BIM standards and guides * A discussion on how various professional roles have expanded through the widespread use and the new avenues of BIM practices and services * A wealth of new case studies that clearly illustrate exactly how BIM is applied in a wide variety of conditions Painting a colorful and thorough picture of the state of the art in building information modeling, the BIM Handbook, Third Edition guides readers to successful implementations, helping them to avoid needless frustration and costs and take full advantage of this paradigm-shifting approach to construct better buildings that consume fewer materials and require less time, labor, and capital resources.

Finally, the shape of the panel profile is trimmed from the stock piece, providing the panel shape, then the positive panel is removed with a negative mold.

FIGURE 10–3–11 Adaptive instantiation of the panels. A 3D intelligent component (Power Copy), which carried information regarding the geometry, material, and installation constraints, was placed in each grid location on the surface, thus adapting each of the components to its own location. The panel connections are indicated with the white spots.

Foreword to the Third Edition

Designers and builders have struggled for centuries to describe three-dimensional buildings on two-dimensional paper, and their contractor partners have struggled to interpret the same drawings when constructing a building.

Occasionally very complex parts of significant buildings were described using a three-dimensional mockup, a smaller version of what was to be built. Brunelleschi created a detailed mockup for his magnificent dome at the Cathedral of Florence, and Bartholdi prepared mockups at different scales for his Statue of Liberty.

Architects then and today build study models to better understand their designs and presentation models to help clients understand how the finished building will look, but these models have little utility in helping the contractor to build.

As an architect, I was trained to describe buildings with drawings on paper. But buildings have three dimensions while paper has two dimensions, resulting in compromises. Drawings traditionally described size and shape, so other information about the building better described in words evolved as specifications, companions to drawings. The purpose of drawings and specifications was to provide adequate information for the contractor to build the building.

Early computers allowed architects to design electronically using Computer-Aided Design (CAD). However, this system was limited to two dimensions and not much of an improvement over drawing by hand. Improved computers at last allowed architects to design buildings in three dimensions using an electronic building model, called 3D CAD. These early efforts to electronically model buildings in three dimensions were helpful, but they were only a beginning.

Electronic building models began with architects, but soon engineers, contractors, and building owners began to dream of adding other useful information to the electronic Building Model, and the word Information was inserted in the center of Building Model to become Building Information Model (BIM).

It is appropriate that Information occupies the central place in BIM, for the rapidly-evolving use of Information is the main driver of a revolution in the building industry. The Building Model origins of BIM are still important but can now be viewed as a small part of the ocean of Information becoming available for use. Information-rich BIM has enabled dramatic change in the processes for designing and building, with big changes just beginning in how buildings are operated for their useful lifetime.

This Third Edition of the BIM Handbook distills the ocean of BIM information into a well-organized, clearly written and illustrated book describing the technology and processes supporting BIM and the business and organizational imperatives for implementation.

Architects, engineers, contractors, subcontractors, fabricators, and suppliers will gain an understanding of the advantages of effective BIM use. Building owners and operators will learn about business advantages generated by effective BIM use. Academic institutions will find the BIM Handbook an essential aid for teaching and research.

The first chapter provides an overview of the book, including building industry trends, the business imperative for BIM adoption, and challenges to implementation. Subsequent chapters survey BIM trends in detail for each building industry participant, and include a summary at the beginning and a list of questions at the end suitable for teaching.

Chapter 9, “The Future: Building with BIM” is an ambitious but well-informed look at what we can expect in the near and midterm future. It highlights the nature of the BIM revolution, explaining “the shift from paper drawing to computer drawing was not a paradigm change: BIM is.” The authors predict that by 2025 we will see thoroughly digital design and construction processes; growth of a new culture of innovation in construction; diverse and extensive off-site prefabrication; strong progress in automated code-compliance checking; increased application of artificial intelligence; globalization of fabrication in addition to design; and continued strong support for sustainable construction.

The final chapter includes eleven detailed case studies in the design and construction industry that demonstrate BIM effectiveness for feasibility studies, conceptual design, detail design, estimating and coordination during construction, off-site prefabrication and production control, and BIM support for facility operation and maintenance.

Authoring a book chronicling the evolution of BIM with depth of detail, yet with clarity and purpose, is a major accomplishment. Yet three of the authors of this third edition of the BIM Handbook—Rafael Sacks, Chuck Eastman, and Paul Teicholz—have collaborated to accomplish this great feat three times (the first edition was published in 2008, followed by the second edition in 2011, both with Kathleen Liston). In this new edition, Professor Ghang Lee of Yonsei University in Seoul, South Korea, has joined the team. Each has been a keen observer and participant in the BIM revolution, and all have collaborated over many years.

Chuck Eastman is a world leading authority on building modeling and has been active in the field since the mid-1970s. He was trained as an architect at the Berkeley CED, where he focused on tool development for practitioners with early versions of Building Information Modeling. He initiated the PhD program at Carnegie Mellon University and founded ACADIA, the North American Academic Building Modeling Conference Group. He joined UCLA for eight years before coming to Georgia Tech, where he has been a professor and director of the Digital Building Laboratory. I have known Chuck for many years and worked with him to advise the Charles Pankow Foundation, which supports research and innovation in the building industry.

Paul Teicholz is professor emeritus of civil engineering at Stanford University. He saw the potential for computers to revolutionize the construction industry as a graduate student at Stanford when programming was still done using punch cards. In 1963, he became the first in the country to receive a PhD in construction engineering and has more than 40 years of experience applying information technology to the AEC industry. In 1988, Paul was invited back to Stanford to create the Center for Integrated Facility Engineering (CIFE), a collaboration between the Civil and Environmental Engineering and Computer Science Departments. He served as the center's director for the next decade, during which CIFE scholars developed computerized tools to significantly improve the AEC industry.

Rafael Sacks is a professor in the Faculty of Civil and Environmental Engineering at the Technion–Israel Institute of Technology, in Haifa, Israel, where he leads the Virtual Construction Lab. He earned a bachelor's degree in 1983 from the University of the Witwatersrand, South Africa, a master's degree in 1985 from MIT, and a PhD in 1998 from the Technion in Israel, all in civil engineering. In 2000, after a career in structural engineering, software development, and consulting, he returned to academia, joining the Technion as a member of faculty. Rafael's research interests extend from BIM to Lean Construction, and he is also the lead author of “Building Lean, Building BIM: Changing Construction the Tidhar Way.”

Ghang Lee is a professor and the director of the Building Informatics Group (BIG) in the Department of Architecture & Architectural Engineering at Yonsei University in Seoul, Korea. He earned his bachelor's and master's degrees in 1993 and 1995 from Korea University, Seoul, Korea, and a PhD in 2004 from the Georgia Institute of Technology. Before his PhD studies he worked at a construction company and founded a dot-com company. In addition to publishing numerous BIM-related papers, books, and international standards, Ghang has developed various software and automation tools such as xPPM, a tower crane navigation system, a smart exit sign system, the global BIM dashboard, and the construction listener. He serves as a technical advisor to several government and private organizations in Korea and other countries.

It has been a pleasure to review the BIM Handbook prior to writing this Foreword. It will be of great value to everyone in the building industry who needs to understand the BIM revolution and its far-reaching effects on practitioners, owners, and society at large.

Preface

This book is about the process of design, construction, and facility management called building information modeling (BIM). It provides an in-depth understanding of BIM technologies, the business and organizational issues associated with its implementation, and the profound impacts that effective use of BIM can provide to all parties involved in a facility over its lifetime. The book explains how designing, constructing, and operating buildings with BIM differs from pursuing the same activities in the traditional way using drawings, whether paper or electronic.
