Since the introduction of Computer Aided Design (CAD) software in the 1960s, industries that design and develop our built environment have been moving from pencil and paper to computers and digital files. The earliest adopters of the new technology were industries like aerospace and automotive, and since then the fields of architecture and design have been enthusiastic adopters. CAD has allowed architects to take previously unimaginable risks in their designs, and to experiment with new forms and materials without the need of building prototypes or performing expensive structural analyses until much later in the process.
Architectural museums and archives are faced with a rapidly growing need to preserve digital information and are grappling with the need for technological tools, technical expertise in digital preservation, AutoCAD expertise, archival expertise, and the need for repositories that can preserve and disseminate the archived data.
The use of 2D and 3D CAD and Building Information Modeling (BIM) software is now routine in architecture and design firms. The contractual deliverable has shifted from printed, wet-signed and wet-stamped drawing sets to an electronically signed model that can be manipulated to achieve equal, if not more, granular information than the traditional printed plans.
Many types of digital files produced during design and construction that are important for long-term preservation for future renovations/restorations and scholarly research.
- 3D CAD models
- hundreds or thousands of detailed 2D layer drawings
- 3D printed objects
- project “out-puts” – for example, drawings or sketches of the building.
- photographs and videos
- websites about the building
- communications among architects, clients, contractors and other parties
Over the last five years, we are seeing that students in architecture and design schools are further routinely using CAD for modelling, skipping the 2D drawing process entirely, meaning that the coming generation of architects will be only producing documentation in 3D models, providing more urgency to the problem of preserving this type of documentation.
The impact of this on the record of architectural innovation and practice –in architecture libraries, archives, museums, among others–is only beginning to be appreciated. No longer can libraries acquire blueprints or drawings, a few images, and a scale model or two, to represent a major work of architecture in their collections. Now they must acquire the 3D CAD models and 2D drawing files, Building Information Models (BIM), digital images, videos and documents, all delivered on a computer hard drive often with no annotation whatsoever. No library or archive is currently prepared for this new reality, but they are increasingly under pressure to figure out how to acquire these 21st century collections, to support the next generation of architectural students and historians.
The Frances Loeb Library at the Harvard University Graduate School of Design received an IMLS National Forum Grant under the National Digital Platform funding priority to support two meetings of engaged stakeholders – architects, architectural historians, archivists, librarians, technologists, digital preservationists, and others who will frame a national/international collaborative infrastructure to support long-term preservation of digital design data. The first meeting will place on April 17th and 18th, 2018 and will provide a venue for the diverse group of stakeholders to think collaboratively about the issues in preserving architectural design data, to find alignments across communities, and to identify the needs required to develop an infrastructure to support archiving of digital design information that will be usable by a variety of types and sizes of architectural museums and archives.
There has been considerable work in this arena over the last five years, and in 2018 there have been three Summits, Symposia, and workshops already that have set the stage for the Forum in April.
Society of American Archivists Design Records Section CAD/BIM Task Force
The Design Records Section Task Force has produced some critical information for the community to help us understand how practitioners, firms, and archives are managing digital content.
This event brought together a wide variety of stakeholders to discuss the issues we face when preserving digital design records. The report has just been made publicly available and can be found here: A Report on the Architecture, Design and Engineering Summit
