Construction Operations Building Information Exchange COBieIntroduction. The handover of a new, or newly renovated, facility is celebrated by the project team, facility occupants, and owners. For those responsible to operate, maintain, and manage that facility, however, the work is just beginning. To start the facility manager begins by unpacking boxes of paper documents and retyping asset information and maintenance schedules into Computerized Maintenance Management Systems CMMS. The pallets of boxes full of paper of operations and maintenance manuals and drawings shown in the figure below are typical of the requirements of contractors complying Unified Facility Guide Specifications 0. No, COBie is format for the publication of a subset of a building model. COBies focus is on delivering building information not geometric modeling. Closeout Submittals, and 0. Operations and Maintenance Data. Facility managers have reported  that this effort may require man years of effort to create and review and transcribe hundreds of pages of documents, validate the transcriptions and manually enter data. To transfer the cost of this manual data entry from the facility manager to the construction contractor, UFGS 0. Facility Electronic Operating and Maintenance Support Information e. OMSI requires the contractor to enter data directly into one specific CMMS. Figure 1. Typical Delivery of Handover Documents. Even if a CMMS is used, mechanics need to search for information in these paper boxes to complete many of their jobs. Over time such documents are moved or lost which increases the cost to complete O M activities and potentially increasing downtime of mission critical facilities. A 2. 01. 1 study  predicted that 8 of the annual maintenance budget could be saved if open standard electronic information were available to the technicians before starting complex work orders. Such savings could allow man years of additional work towards backlogs or needed renovations.

In 2. 00. 7, the Construction Operations Building information exchange COBie requirements analysis report  proposed a new way for designers and contractors to directly provide electronic operations, maintenance, and asset management information as that information is created. Following an on site study of COBie at Fort Lewis Washington, a proposed UFGS specification  was developed for design build and construction contracts. Further investigation of COBie compared the life cycle costs of current and COBie based processes  and demonstrated that tens of thousands of man hours or large projects are spent in performing redundant tasks trying to handle information locked in documents. Simply understanding, documenting, and proposing the information needs of operators, maintainers, and facility managers is insufficient to have COBie be used in practice. In parallel efforts the Engineer Research and Development Center, through the building. SMART alliance, worked to establish COBie as an internationally recognized open standard implemented in over 3. Commercial Off The Shelf Software COTS systems. Description. COBie is a performance based specification  for facility asset information delivery. Two types of assets are included in COBie equipment and spaces. While manufacturer data for installed products and equipment may one day be directly available via the SPie project, COBie helps the project team organize electronic submittals approved during design and construction and deliver a consolidated electronic O M manual with little or no additional effort. COBie data may then be imported directly into CMMS and asset management software, again at no cost. The PDF, drawing, and building information model files that accompany COBie are organized so that they can be easily accessed through the secure server directories already in place at the facility management office. The federal governments requirement for delivery of Real Property Inventory RPI information may be met by COBie. While the technical details of COBie can appear complex. COBie files are not intended for end users. COBie provides system to system exchange of the space and equipment information without user intervention. Consider COBie and similar information exchange projects to be a kind of ASCII for buildings. Today, people dont need to know ASCII to use a web browser, email system, word processor, or other software the words just come along because of ASCII. In the same way, once we have achieved COBie everywhere, only a very few programmers will need to give COBie a second thought. To make COBie as useful as possible COBie data is available in several formats. Web portal for buildingrelated information with a whole building focus provided by the National Institute of Building Sciences. Areas include Design Guidance. Software system exchanges during the design process could use the STEP Physical File Format ISO 1. Part 2. 1 files conforming to the Industry Foundation Class ISO 1. COBie Model View Definition. When people want to look at the COBie data directly, and they do not want to learn to read complex STEP file formats, they can use a translation of data into a spreadsheet. Cheap Pine Sans Font. Building Construction Process Step By Step Pdf' title='Building Construction Process Step By Step Pdf' />Examples of COBie files of different formats, and at various stages of design and construction, can be found on the Common BIM Files page. COBie spreadsheet templates may be found on links at the bottom of the COBie Means and Methods page. Exchanges of small bits of COBie data about individual assets is another type of exchange supported by COBie. For example, an entire file need not be exchanged simply to update the installation date and serial number of a specific piece of equipment. These individual COBie transactions can be captured through National Information Exchange Model format called COBie. Lite. Application. As in any other part of a design or construction contract, the quality of the product received depends on the ability of the designer or contractor to meet the specification. Before COBie, there was little need to clearly define the quality of the data provided since the volume of paper documents provided effectively prohibited more than a cursory review of the construction handover documents. Since COBie offers the possibility to automatically check the equality of electronic handover documents, the best owners will be sure they consider what to include in their COBie specification. There are three sets of decisions owners can make to ensure that they get the information they need through COBie. The first is to specify the classifications they already use to organize existing CMMS data. If there is no CMMS data, COBie provides a default classification system, Omni. Class, provided by the Construction Specifications Institute. The second set of decisions owners can make is to limit the set of scheduled information provided via COBie to only those assets that are actually managed or maintained. Finally, the owner can identify the specific properties to be mandated for each of these assets. Here again the default position is that COBie data simply reflect that data found on the drawing schedules. In most cases, such a level of detail will be well above the information currently captured. A brief video introduces COBie for owners. From the designers point of view, COBie data is simply the compiled set of all the schedules found on design drawings. Design software has been working hard since 2. COBie data that matches their drawings. To ensure that design schedules can be properly exported to COBie designers should follow the instructions provided by their design software product.
