classification, similar to how the social media and web browsers learn the user’s preference and behavior. The ranking of each recommended attribute evolves accordingly, and the recommendations get aligned to the users’ needs. Data Management Throughout the Project Lifecycle The DDMS establishes data connections to multiple platforms (i.e. Excel, Revit, SAP, and Maximo®) and acts as a central hub of all the data streams. This capability allows the DDMS to bridge the gaps in data management and benefit the entire building lifecycle. From the PIM to the AIM perspective, the DDMS serves as a synchronized plat- form that conveys all the owners/facility managers’ data requirements. As previously mentioned, one of the issues during the IPD process is that facility management’s requirements fail to be incorporated into the project delivery (see Figure 1). Here this FM-oriented DDMS could offer a nice remedy. The data dictionary of assets and attributes can be packaged into different Shared Parameter packages in PIM based on the project stage and discipline. Each stakeholder can incorporate the parameter groups that they are responsible for in their PIM and gather necessary information during the building design and construction process. In this fashion, each stakeholder won’t be overwhelmed by a full list of required inputs that are not relevant to them, and there is no ambiguous naming convention and missing information at the end of the project delivery (and no-one needs to care if COBie, or Uniforma are being followed). The DDMS also serves as the QA/QC during the handoff process. It can check the model information against the re- quired data information and attributes, and provide a completion score and data analysis breakdown as the reference for the next round of the model submission. From the CMMS (e.g., Maximo®, SAP) perspec- tive, the data dictionaries hosted on the DDMS can be fully exported into a CMMS compatible format for example, MxLoader for IBM Maximo®. This capability of the DDMS saves an incredible amount of time for the CMMS implementor. By default, the implemented data dictionary would have been through the purification and standardiza- tion process in the DDMS already, which makes the implementation process even more smooth. Lastly, from the onsite data collection perspective, the DDMS facilitates the onsite data collection process by providing an easy to use interactive web application on a phone or tablet with the most updated information without users wasting time on fishing through the legacy spreadsheets. Figure 6 illustrates how DDMS could help streamline the project lifecycle from delivery to the operational phase.

A Sample Application of the DDMS Here is a case study of a large agency that uses this FM-oriented DDMS to help them build the Enterprise Level Asset Management Data Dictionary. This United States government agency has an exten- sive portfolio of facilities and departments, most of which have their own database, platform, and classification means and language. As part of their EAM (Enterprise Asset Management) program, they wanted to migrate their data from the legacy systems into the EAM system. In order to integrate all of those systems into one, they have to develop a well-rounded data dictionary that can encompass all facilities and departments. Their initial attempt was to develop systems via Excel spreadsheets. As a result, they ended up with numerous Excel spread- sheets that could hardly be managed and synchronized. They chose to utilize a DDMS for their roadmap. They first applied the DDMS to consolidate all the data dictionaries across different facilities into a synchronized one. After the establishment of their unique single data dictionary, applicable for every facility within the organization, they were able to shift from historically siloed asset management practices to a more integrated and collaborative approach. By capitalizing on all the previously introduced functionalities that the DDMS provides, it helped the agency substantially reduce its overall program imple- mentation time and significantly save agency costs. The DDMS will play an important role in conducting the data flow from delivery to operation phase for future projects even after the data dictionary has been completed. Summary The development of the custom FM-oriented DDMS and its func- tionalities originated from the need for a solution to bridge the gaps between PIM and AIM and solve the issues during the asset manage- ment practices. Based on experiences and feedback, the DDMS makes considerable improvements for the agency’s current practice in Asset Management. It is expected to change and improve the entire BIM driven lifecycle. As illustrated in Figure 7, the first level - Project Development Level generally breaks down the building develop- ment phases, includes plan design, construction commissioning, and operations and maintenance. These phases might be slightly different depending on the contractual styles, i.e. Design-Bid-Build or Design- Build, but they could be very similar.
