Many of the projects that follow involve existing facilities, as such projects represent a much larger share of our world than does new construction. The Case Studies, Design Fictions, and Workflows detail both the possibilities and results that come from real-world projects completed by BIG-BIM practitioners as they work to achieve better managed assets in the built environment.
Much has been learned as owners, designers, planners and constructors have worked to achieve the results that BIG-BIM promises. Much has been learned as enterprise owners work to incorporate their existing facilities, or add new facilities within established campuses or distributed networks of buildings. Across the board, these three lessons hold to be at the heart of the process:
- Start little-bim installations one building at a time. A phased approach to as-built models is often the only solution when there is a requirement to deliver standalone little-bim, because funding to document existing conditions is often limited, even for the largest owners.
- Start BIG-BIM installations so that all facilities within a campus or portfolio are modeled in a quick, low level of detail manner to act as the data buckets to hold owner information that will be attached to the ecosystem. The contextual and decision support benefits of BIG-BIM take much too long to emerge when you use a traditional process of fully developing one building at a time at a high level of graphical detail.
- Get immediate benefit by creating Current Condition Models in BIG-BIM to hold legacy information (areas, coordinates, program data, and planning rules). These models can be upgraded to include geometry and detailed facility data over time, as budgets allow.
Models are ideal candidates for rules-based systems. Start by modeling the first project. Each additional project should take the same course. As the owner renovates or replaces facilities, the models become ever more precise. They build up the institution’s storehouse of information. Connect these models to other asset data using BIG-BIM as middleware.
Portfolio owners within multiple facilities can have any building or use type. They can have new projects or renovations. They can involve infrastructure assets, or not. In this environment, the capital improvement plan is king. BIG-BIM of the entire portfolio is an ideal way to manage this complexity.
The management and elimination of deferred maintenance are a constant in extensive facilities and multi-building campuses. Budget restraints often force managers to focus on one capital improvement project at a time. Owners face a dilemma of where to apply limited funds. The ability to manage deferred maintenance is one of the major benefits of a BIG-BIM ecosystem.
For enterprise owners, the best solution is to develop a BIG-BIM ecosystem that includes models containing site information and massing models for facility assets. Projects within the model can take many forms, depending on the available information. Existing installations may start as little more than boxes to hold legacy data. As projects are developed the BIG-BIM ecosystem captures the results and becomes richer.
Information moves from conception to planning, design, and construction into operations and maintenance. At each step, the BIG-BIM ecosystem becomes more resilient, sustainable, and economical. Value builds as the owner learns how to connect to capital budgets and facility processes. Those able to plug into the process become valuable. In fact, they may be indispensable.
