use their existing map of information to push and pull information into the Maximo system. The process that developed at DIA and other infrastructure locations allows this approach to be used by MEP and structural engineers. The approach has been proven to be useful in fixed structural assets such as bridges and is being extended to tunnel infrastructure. Impact on owners From the owner’s perspective, the construction process contains rich data sets that are needed in operations and maintenance. Unfortunately, the traditional methods of data delivery require additional time and money to get the information into the hands of the operations and maintenance staff. This time has been measured as somewhere be- tween six and 18 months to process the close-out packages, extract the data, and convert the data to something a computerized maintenance management system (CMMS) can use. This process using ModelStream greatly reduces the time to data deliv- “Day One” operational support is the holy grail of facility maintenance and operations, where at the end of major construction, the assets and related data and reference documents are loaded into an asset man- agement system. On this first day of operations and maintenance, all relevant information about the assets is made available to facility staff. ModelStream allows the industry to get one step closer to Day One operations by streamlining the data transfer process from a unified as- built model into an operations and maintenance CMMS. In addition, operations staff can view the 3D model information and all related data while inside Maximo through the introduction of a Model Viewer Tab. This Model Viewer Tab allows the facility technician to see where the asset is located and what equipment is around the asset. The Autodesk Forge platform is used to display the 3D models without a need to have Autodesk Revit installed. The Autodesk Forge Platform is a browser-based system for viewing 2D and 3D drawings. Implementation challenges As with any data management system, complexities of implementation always come up. In this case, the challenges revolved around ensur- ing the Maximo system for the development staging and production environments were of similar Rev levels for data consistency across each platform for populating assets. All information updates were handled through the specifications or classifications in Maximo and then through an automation process. ery for operations and maintenance. Asset management impacts The main technical issues were Maximo patch level differences among the environments and network/firewall that had to be worked through. The firewall issues were mainly getting its exceptions from the hosted Maximo environment to the Forge platform. As a part of a separate effort, DIA realized the BIM process had to be modified to add placeholders for the data they were looking to collect and eventually transfer to Maximo. Even though the data didn’t exist
yet, the placeholders allowed for the creation of the mapping files. All the additional parameters were created at the instance level in the mod- els to allow for individual values (as opposed to global values that are placed at the family level). This provided support for using the model as a facility model. DIA wanted to have Maximo auto number the assets, but also be able to see what a particular element in Revit was linked to in Maximo. To accomplish this, we set up an inbound (Maximo to Revit) mapping that brings the value for the “assetnum” field back into the Revit model after it is loaded in Maximo to give full visibility. Conclusion What this and other projects like this have shown is that BIM does have a role within operations and maintenance. The Single Source of Truth model may not currently exist, but there is a role for a federated data model with BIM as the primary source of information. What is left for the facility maintenance and operations industry to figure out is if the 3D model itself has a useful role in operations and maintenance. The 3D model allows the facility staff to view and examine the work area prior to going into the field. Future integrations of technology will allow the 3D model to be used in the field for the “behind-the-wall” view. However, for the industry to get there, a robust BIM workflow must be in place to ensure the data is consistent and reliable.
