When properly deployed on a very low-latency/high-bandwidth network, a distributed WAN can allow multiple parties to access a single Revit model. In the Revit environment this shared WAN is typically supported by the use of network accelerators, the most common of which is Riverbed Appliance. The most popular way to share project data is the extension of a company Wide Area Network, or WAN, allowing partners to directly access shared project data. The options listed below will focus on tools available for the Autodesk Revit platform, but many solutions now exist for most BIM authoring tools. However, new advancements in BIM tools have opened up cost savings opportunities for BIM data creators. Until recently the only option available was the fractured workflow. You will have to remodel the data in a format that supports the ability to add the attributes and grouping required by the Standard. For example, if the sheet metal fabricator worked in FabMEP, you can't import that data into a format that meets GSA BIM Guidelines for Revit.
In many cases this may require the data creator to completely remodel the data. The simplest but most costly option is to maintain the legacy practice of model fracturing and then manually reconcile all the data to a single BIM at the end of the project. You can be accomplish this in several ways, your team will need to develop strategies that best suit your needs.Īs the data creators, your team must decide which strategy meets the project's goals and required deliverables. Although not required, sharing the project dataset is the only path to minimal waste in the development of the required unified deliverable at project completion. Sharing the project dataset is one recommended workflow to achieve a unified model. When a building owner has multiple sets of conflicting data, it is nearly impossible to leverage the data for facility automation and management. In today's BIM-based world, GSA is no longer willing to accept this fractured dataset as a final deliverable. Besides being very costly and inefficient, this process is prone to errors and almost always leaves the owner with two disconnected sets of data at the end of a project. The design team would continually issue addendums, revisions and bulletins, which the fabricators would reference to adjust their drawings. In a simple 2D world this fractured environment, although very inefficient, can be managed. From this moment on, you have a fractured model environment. The fabricators will begin developing fabrication level data from that original dataset. Often a project team will hand over a copy of their 2D and 3D data to the fabricators as soon as the fabricators become involved in the project. This disconnect occurs as soon as the project fabricators become involved with the project. For years a disconnect has existed between design and construction documents.
