"Ordnance Supply Problems in the Canadas: The Quest for an Improved Military Transport System, l814-l828" by Robert W. Passfield, in HSTC Bulletin: Journal of the History of Canadian Science, Technology and Medicine, Vol. V, No. 3, September l981, pp.187-209. This article sets forth the military transport problems experienced by the British Army during the War of l812, and traces post-war efforts to develop a safe interior communication independent of the St. Lawrence River. The efficiency and operating costs of rail, road, and canal are compared in their contemporary state of technological development ca. 1825, and in the context of the Upper Canadian environment, in an assessment of why the British Ordnance Department ultimately opted for the construction of a military canal through the interior of Upper Canada.

“A Wilderness Survey: Laying out the Rideau Canal, 1826-1832" by Robert W. Passfield, in CIS Centennial Convention Proceedings (Ottawa: Canadian Institute of Surveying, Vol. l, l982), pp. 291-313. The laying out of a canal was one of the most difficult tasks that a 19th century surveyor could undertake, but even more so in a heavily-forested wilderness environment where traditional surveying methods were largely inapplicable. This paper comments on the surveying systems employed in the British Army's topographical survey in Britain, and traces the adaptations that had to be made, and the bush surveying techniques that were adopted, in laying out the Rideau Canal through a tract of wilderness. This paper was subsequently reprinted, at the request of the editor, in the HSTC Bulletin: Journal of the the History of Canadian Science, Technology and Medicine, Vol. VII, No. 2, May 1983, pp. 80-97.

The importance of this article in conveying to the international heritage community the mandate of Parks Canada, and the scope and nature of Parks Canada’s involvement in researching, recording, and preserving industrial heritage sites and artifacts, is underlined by its being cited in an article by Christopher Andreae and John D. Light, “Industrial Archaeology in Canada: a Binocular View” (IA: The Journal of the Society for Industrial Archeology, Vol. 25, 1999, pp. 65-71) on the development of industrial archaeology in Canada. Andreae and Light point out that throughout the 1970s and 1980s it was Parks Canada that “not only had created but also had set and maintained the standards for the practice of both historical and industrial archaeology throughout the country”, in the general absence of formal courses and field training in the discipline of industrial archaeology at Canadian universities at that time.

“The Turcot Riveted-Arch Truss Bridge: ‘As rigid and unyielding as a stone arch’” by Robert W. Passfield, in IA: Journal of the Society for Industrial Archeology, Vol. 23, No. 2, 1997, pp. 21-48. This article provides a brief history of an unusual riveted-arch truss bridge discovered at Georgetown, Quebec. It establishes the association of the bridge with a long-forgotten provincial bridge building program in Quebec, “La politique des ponts métalliques” (1887-1892), which was introduced by Gérard Macquet, a Belgian engineer engaged by the provincial government. The article places the Turcot Bridge within the context of the introduction of riveted-truss bridges to North America; European influences on metal truss bridge design; the transition from pin-connected wrought iron to riveted mild steel truss bridges; and the pioneering of provincial highway bridge design standards. Six surviving Macquet riveted-truss bridges were located, dated, and identified according to their novel truss types, and were placed within an historical context. (The editor’s preface to the IA journal issue refers to this article as “a classic example of industrial archeology”.)

Canal History and Technology Proceedings   
“Construction of the Victoria Tubular Bridge” by Robert W. Passfield, in Canal History and Technology Proceedings (Canal History and Technology Press: Easton, PA), Vol. XX, 2001, pp. 5-52. This paper traces the design evolution and construction of the 6,592 foot-long tubular railway bridge erected across the St. Lawrence River at Montreal in 1854-1859. It relates how the world`s then-greatest bridge construction project was transformed from a looming failure into a triumph of bridge construction engineering through the introduction of innovative steam-powered construction machinery. The Victoria Bridge is placed within the context of the design evolution and construction of tubular bridges in Britain; and the failure of the tubular bridge prototype to establish itself as a long-span structure in competition with the wrought iron truss bridge in both North America and Europe, is examined and explained from a technological viewpoint. Lastly, the role of Canadian contractors in bringing the bridge construction project to a successful conclusion through the introduction of innovative steam-powered boom derricks, travelling gantry cranes, and centrifugal pumps, is set forth; as well as the impact of the construction of the Victoria Tubular Bridge on Montreal and the development of Canada’s railway transportation and trade patterns.

"Evaluating Authenticity: Reconstructed Timber Swing Bridges" by Robert W. Passfield, in IA: The Journal of the Society for Industrial Archeology, Volume 31, No. 2, 2005, pp. 5-26. When Parks Canada acquired the Rideau Canal in 1972 under a mandate to preserve its historic structures, there were five reconstructed timber bridges extant on the waterway. Subsequent research revealed that the design prototype for the timber swing bridges had been introduced on the Rideau Canal in 1866; that the bridges had evolved within a continuing traditional culture of conservation through replacement-in-kind reconstructions; and that the swing bridges had been reconstructed at 12- to 15-year intervals over the course of more than a century. This article evaluates the authenticity of the five reconstructed timber swing bridges within that particular cultural context to determine whether they were 'what they were purported to be' - an evolved integral form of the original timber swing bridge that conserved the genuine heritage values that conveyed the significance and character of the original structure within its setting. In so doing, the article adapts and applies the revised test of authenticity developed by the UNESCO World Heritage Centre at the Nara Conference on Authenticity (Nara, Japan, November 1994) to industrial archaeology and provides a case study of a new approach to industrial heritage evaluation that recognizes reconstruction as a legitimate conservation approach.

“St. Andrew’s Caméré Curtain Bridge Dam, Lockport, Manitoba” by Robert W. Passfield, IA: The Journal of the Society for Industrial Archeology, Vol. 33, No. 2, 2007, pp. 4-34. This article describes and analyses the design evolution and construction of a moveable curtain dam that was constructed across the Red River at the St. Andrew’s Rapids in 1907-1910 by the federal Department of Public Works. A novel type of moveable dam developed in France, it was constructed on an unprecedentedly large scale in Canada and adopted to electrical power operation. A postscript comments on the heritage value assessment that led to its commemoration in 1990 as a structure of ‘national historic and architectural significance’, and describes the restoration work undertaken subsequently to ensure its conservation.

“Forging a Multi-faceted Discipline: A Review Essay”, by Robert W. Passfield in IA: The Journal of the Society for Industrial Archeology, Volume 38, No. 2, 2012, pp. 69-74. [Submitted: August 2013; published: July 2015] This review essay provides a succinct summary of the origin and evolution of the industrial heritage field, the best current practices in the recording, preservation, and presentation of industrial heritage sites world-wide, as well as comment on the ‘re-tooling’ that the field has undergone since the 1950s in its expansion to include industrial cultural landscapes, industrial processes, urban regeneration, eco-museums, and the working life of industrial communities, as presented in the book under review. The mandate and organization of TICCIH (The International Committee for the Conservation of the Industrial Heritage), is also set forth. In doing so, the review essay provides a synthesis of the contributions to the book of 34 international specialists -- members of TICCIH – on the ‘re-tooling’ of the industrial heritage field and the current state-of-the-art. Lastly, comment is provided on the problems inherent in seeking to define “authenticity” and “integrity” in the evaluation of industrial heritage sites, and on the factors that will need to be taken into account in the potential development of an epistemology for evaluating the ‘outstanding universal value’ of industrial heritage sites.
