59 5.1 Developing the BIM Life Cycle Process Unlike BIM for design and construction, life cycle BIM is concerned with a process of developing and maintaining the data for an entire facility, not just for one project. This Guidebook refers to the BIM life cycle phases as planning, design, construction, operation, and renewal.

BIM Implementation -- BIM Process 61 For example, considerable cost and effort can be expended in modeling all the mechanical, electrical, and plumbing (MEP) infrastructure -- including piping, conduits, ductwork, process mechanical, cable trays, and hangars.

62 BIM Beyond Design Guidebook BIM process maps are the standard mechanism for documenting life cycle activities utilizing BIM. They are flowcharts that identify specific actions, required facility data inputs, facility data created, and who is responsible for each activity.

64 BIM Beyond Design Guidebook 5.5.1 Asset Selection When developing BIM for design and construction, a high LOD is required to coordinate the construction activities. Even minor assets that are not modeled can create unforeseen conflicts when the trades are installing heating, ventilation, and air conditioning (HVAC)

BIM Implementation -- BIM Process 65 While there is no standard reference for asset attributes, there are classification standards that can be referenced if there is not an established internal airport standard in place. The standard asset classification systems include OmniClass, UniFormat, Construction Operations Building Information Exchange (COBie)

66 BIM Beyond Design Guidebook BIM roles and responsibilities include the following: • BIM champion -- a member of the executive team who promotes the BIM vision • BIM steering committee -- the interdepartmental team, created to define strategy, develop the business case, and work with executive staff to get approval and funding for the BIM strategy and implementation • BIM manager -- has overall responsibility for executing the BIM strategy • BIM designers -- responsible for creating and maintaining BIM • BIM asset managers -- responsible for defining and maintaining the accuracy and completeness of BIM • BIM procurement/legal -- responsible for identifying and maintaining BIM contractual and legal requirements • BIM IT -- responsible for maintaining the network infrastructure to support secure BIM • BIM leads -- BIM leaders within each department who are knowledgeable and can promote the use of BIM to improve department processes and provide feedback on potential opportunities for improvement A decision will need to be made on where the role of BIM manager falls. The survey of airports conducted for this research showed that most airports placed BIM management within an engineering or asset management department.

BIM Implementation -- BIM Process 67 • Technology (software, hardware, information) – Fundamental technology – Management technology The value of the roadmap is that it communicates the overall direction of the BIM strategy over time documenting the key tactical elements needed as well as sharing the long-term vision for the effort.

68 BIM Beyond Design Guidebook 5.9 BIM Development and Maintenance Unlike BIM developed to support design and construction, a life cycle BIM must be maintained over the life of the entire facility to provide any long-term benefit. Developing BIM handover requirements on capital projects can be a means of creating a BIM foundation for an airport.

BIM Implementation -- BIM Process 69 only update a portion of the overall facility. The airport must create and maintain a consolidated BIM that, at a minimum, covers an entire facility.
