There is an increasing recognition that, to maximize the benefits of Building Information Modeling (BIM), it should be deployed in such a way that it remains useful beyond the design and construction phase of projects. This means that it should be utilized in the facilities management phase of a constructed facility. This paper focuses on the identification of benefits gained from the effective integration of BIM in Facilities Management. Drawing on literature from previous research, it argues for the adoption of strategic approaches towards holistic consideration of benefits. The paper also presents the findings of a preliminary case study based on exploratory interviews with key personnel on a major university building project, and review of project documents. Qualitative descriptions of benefits were obtained from these interviews and are summarized in the paper. The paper concludes with a discussion of the benefits of BIM/FM integration, with a view to a comprehensive determination of project gains within the lifecycle of a project. The paper offers some conclusions that are aimed at the holistic consideration of benefits through the project phases preceding handover and including those in the lifecycle stage for a more wholesome assessment of the effectiveness of BIM implementation in FM.
The Windsor Bridge provides a two-lane highway crossing of the Susquehanna River in Broome County, New York. The structure comprises three 62.5-m (205-ft) simple-span through trusses supported by reinforced concrete abutments and solid-shaft piers. Having been built in 1935, it required rehabilitation in the early 1980s. The major effort included a deck replacement and complete structure repainting. What was expected to be relatively minor surface restoration of the foundation units became much more involved and complex. A coring program was initiated for predictions of the volume to be restored. The cores were petrographically examined and found to exhibit evidence of freeze-thaw damage and alkali-silica reactivity of the aggregate. The shafts, which were 2.13-m (7 ft) thick, were found to be delaminated from the freeze-thaw damage to depths of up to 610 mm (24 in.). An intensive evaluation of alternatives concluded that the most appropriate solution for this situation was to encapsulate the pier shaft with a concrete shell 305 mm (12 in.) thick with through-shaft posttensioning to retain the deteriorated existing concrete. This innovative solution is believed to be extremely unusual, if not unique, in the United States. Many unusual design-related issues were encountered while developing the plans for restoration. The background of the initial evaluation, development of alternatives, design philosophies, and general issues associated with the construction are presented. Thermosensor findings are also included, which yielded interesting and unexpected results. The knowledge gained from this project can be useful to other consultants and bridge owners.
