Prefabricated Systems

For a number of years, modular construction – the use of prefabricated elements in architecture – has once again become a subject of lively discussion and debate. Long written off as monotonous, today’s building components are actually highly differentiated and capable of supporting and enhancing the architect’s creativity. Numerous structures work with prefabricated components; for single-family homes the figure is ninety-eight percent, and modular systems are available that meet high aesthetic standards. This book provides an overview of the various different systems and their possible uses, particularly in the areas of housing, office, and industrial buildings. It explains the processes and components of modular construction and the behavior of the various materials when this construction approach is used. The authors offer strategies for planning and designing with prefabricated systems so that the architect can use them productively. Numerous drawings explain the principles of modular construction, while built examples forge a link between those principles and the practical activity of building.

TRB's National Cooperative Highway Research Program (NCHRP) Synthesis Report 324: Prefabricated Bridge Elements and Systems to Limit Traffic Disruption During Construction assesses and documents the use of innovative prefabricated elements and systems and assesses its effects on on-site construction time and cost, closure time, and environmental impacts. The synthesis report also looks at the use of fiber-reinforced polymers and other advanced materials and new technologies that are gaining in popularity but are still in the experimental stages.

Provides information on woven and non-woven geotextiles used for filtering and drainage in geotechnical engineering. The design of such filters balances large pores for adequate permeability with smaller pores for proper soil retention. Of the 15 papers from a June 1995 symposium in Denver, Colorado

"Prefab Architecture . . . is beyond theory, and beyond most of what we think we know about pods, containers, mods, and joints. This book is more than 'Prefabrication 101.' It is the Joy of Cooking writ large for the architecture and construction industries." From the Foreword by James Timberlake, FAIA THE DEFINITIVE REFERENCE ON PREFAB ARCHITECTURE FOR ARCHITECTS AND CONSTRUCTION PROFESSIONALS Written for architects and related design and construction professionals, Prefab Architecture is a guide to off-site construction, presenting the opportunities and challenges associated with designing and building with components, panels, and modules. It presents the drawbacks of building in situ (on-site) and demonstrates why prefabrication is the smarter choice for better integration of products and processes, more efficient delivery, and realizing more value in project life cycles. In addition, Prefab Architecture provides: A selected history of prefabrication from the Industrial Revolution to current computer numerical control, and a theory of production from integrated processes to lean manufacturing Coverage on the tradeoffs of off-site fabrication including scope, schedule, and cost with the associated principles of labor, risk, and quality Up-to-date products featuring examples of prefabricated structure, enclosure, service, and nterior building systems Documentation on the constraints and execution of manufacturing, factory production, transportation, and assembly Dozens of recent examples of prefab projects by contemporary architects and fabricators including KieranTimberlake, SHoP Architects, Office dA, Michelle Kaufmann, and many others In Prefab Architecture, the fresh approaches toward creating buildings that accurately convey ature and expanded green building methodologies make this book an important voice for adopting change in a construction industry entrenched in traditions of the past.

Prefabricated and Modular Architecture demystifies age-old perceptions surrounding prefabrication and modularization of buildings, offering a fresh approach to design and procurement. Experienced architect, William Hogan-O'Neill, provides a unique insight into why architectural design, manufacturing and assembly processes must coexist in parallel. In order for the architectural profession to have a meaningful existence in the future, it must examine the new opportunities that are emerging through automation and artificial intelligence from within the factory environment, as opposed to the construction site. In addition, the book explores the following topics; core elements defining prefabrication; perceptions and influences; precision, exactness and tolerances; standardization and economies of scale; panelized versus modular buildings as a design solution and, finally, common features, technical considerations and certification.

Building is a system of energy and environment, which needs to accommodate diverse needs and demands at individual and societal levels. Nearly 40% of global energy use derives from construction. In fact, a house consumes a significant amount of energy before and after occupancy, and the associated CO2 emissions are contributing to climate change. Prefabrication is a means to mass-produce buildings or parts and components. Thus, in theory, production costs can be reduced through economies of scale. In the 1920s, the significance of mass-produced houses was widely propagated by Le Corbusier who saw standardization as fundamental to mass production. Nonetheless, today, in response to growing global warming issues and the constant increase in energy prices, the construction industry is becoming more responsive to the delivery of sustainable architecture than ever. Within this context, sustainability may embrace not only building economy but also the adequacy beyond the legitimacy in which the quality barely coincides with individuals’ various dynamic needs, desires, and expectations today. In this respect, mass-produced prefabs alone fail to realize total sustainability. In 1987, a paradoxical concept of mass customization was introduced by Stanley Davis. Nonetheless, the idea applied to housing dates back to the 1950s. The essence of mass customizable architecture was speculated by Walter Gropius, as he emphasized the need for standardizing and mass-producing not only entire buildings but also their components. The combination of standard building components, which can be prefabricated, results in mass producing various types of constructions through economies of scope, where the quality can be defined by user choices of the components given in consideration of economic constraints and needs and demands. This book is an initial attempt to integrate the two notions of sustainability and mass customization by reviewing the potential capacities of prefabricated construction.
