  • • Major BIM collaborator • Prior relationship equalled TRUST • Motivated to learn • Integration of structural and architectural models was a key joint goal • Change in communication critical Bornhorst + Ward Structural Engineering
  • • Major BIM collaborator • Contracted initially for mechanical services, later contracted to model fire services and cable trays for other subcontractors • CAD Duct caused difficulties translating model information into BIM • Unfamiliarity with Design Development process • Benefitted greatly from prototyping process as the mechanical services are being fabricated in Brisbane and shipped to Townsville. VAE Group Mechanical Subcontractor
  • • Lead services consulting engineer • No documentation beyond Design Development • Engaged by Hollywood Plumbing (plumbing sub- contractor) to model hydraulics services in Revit WSP Group Mechanical, Electrical, Hydraulic and Fire Services Engineering
  • • Started in Jan 2013, after construction documentation was completed. • Model has been incorporated into both Revit and Navisworks and checked against existing structural steel modelling and architectural detailing. CASA Engineering Steel Fabricator
  • • Consultants novated to Hutchinson’s during Design Development. • Influential in getting subcontractors to contribute to the BIM. • Hutchinson’s Primavera construction programme was integrated into the Navisworks BIM. • Foreman on site is making use of the Navisworks model to supplement existing documentation.

  • BIM Execution Planning • Initially driven by us, the Fast track, D & C compressed time frame limited our ability develop and resolve the BIM EP fully • Based upon NATSPEC template, the initial documents are overly complicated and daunting • Ideally should be managed and driven by the architect, with authority.
  • Index of NATSPEC BIM EP Sections deleted shown in red.
  • Embracing Change • Structural engineer modelled concrete to architects dimensional set out requirements • Architect used structural engineers and subcontractors services models for integrated documentation • Communication urgency and forward planning • Prototyping the building rather than documenting a contract
  • Architecture Structure Concrete Set Out
  • Architecture Structure Services Leveraging Model Information
  • Leveraging Model Information Additional set out visuals for concrete package
  • Project Team Action List Contains model views, sketches and notes
  • Bring Decisions Forward to Reduce Time & Cost
  • Element Ownership Schedule Mapping out the dates of ownership exchange

  • Revit Sun Shading Prototype 3D Sectional Study in Revit, Engineering Analysis
  • Integrated Revit Model (Architectural, Structural and Services)
  • Integrated Revit Model (Architectural, Structural and Services)
  • Sectional views through Navisworks model
  • Concrete set out drawing – model elements from structural model, all dimensions provided by architect. Linking the structural, mechanical, hydraulic and steel fabrication models into our Revit model. Confirm detailing with the steel fabrication model in Revit during CA Documentation
  • FM Pilot from Building Information Model to intelligent Building Information Management
  • Facilities Management By considering the FM Ready modeling requirements at the initial stages, it is possible to produce a model that is useful throughout the full building Lifecycle. • This is important to the client, as:  the majority of the interoperability losses are borne by owners, and  the majority of expenditure is incurred during the operational phase. A Hospital's maintenance cost is equivalent to the capital cost every two to thee years!! 12% 22% 66% Planning, Design, & Engineering Construction Operations and Maintenance NIST GCR 04-867, Cost Analysis of Inadequate Interoperability in the U.S. Capital Facilities Industry • 66% of interoperability losses are borne by owners • $0.23/ existing SF/year
  • Facilities Management • Objective:  To pilot Facilities Management integration as a learning exercise for the key project participants. – Client desired an FM Ready model – Not mandated in the Contract – Approach freed participants to invest in innovation without contractual risk.
  • Facilities Management • Process: 1. We Specified FM Ready Model requirements. 2. We Clarified throughout the project. 3. We Verified by integrating to a real FM system.
  • The Role of the Model in FM The Model acts as the link between model elements and information to be loaded to the FM System. 1) COBie schedules (Construction Operations Building information exchange) contain most of the data 2) Commissioning & Handover Documentation is linked to the model Revit + COBie Plug-in COBie Schedules Facility Management System Input from Consultants, Contractor and Subcontractors Navisworks Commissioning & Handover Documentation
  • The Role of the Model in Commissioning & Handover for FM
  • The Role of the Model in Commissioning & Handover for FM The handover information is linked to the objects, equipment systems and major assets and is accessible easily via the model.
  • The Role of the Model in Commissioning & Handover for FM E.g. Isolate the AHUs and select an object to see all linked information. Retrieve all relevant documentation (e.g. specs, test reports, technical information, manufacturer’s data, etc.)
  • The Role of the Model in FM Operations The Model acts as the visual navigation interface for integrated FM Applications
  • FM iBIM Video Demonstration Visual Navigation Interface Demonstration Scenario: We are currently working in our FM Work Order system, checking real-time operational performance stats - when we get a call about the air conditioner in Retail 1. • Before we create a work order we want to identify the unit • Check to see if a service request is already in the system • See if this type of unit has issues in other locations
  • FM iBIM Video Demonstration
  • Facilities Management • Learnings  Stakeholder and project team engagement, clarity and commitment is key.  Process is more about identification and management of assets and information critical to operation.  Remember the ultimate audience for the model and keep naming/description conventions consistent and de-jargoned.  Once the participants know what is required there is relatively little ongoing overhead for them contributing to an FM Ready model.

  • • Model collaboration pushed within the limitations of Revit for a phase 2B project. • Changes of communication processes and forward planning are key. • Significant time investment required to manage BIM processes. • BIM Execution Plans will become a vital document, ideally should be managed and driven by the architect with authority. • Design and Construct projects are conducive to the delivery of a phase 2B project. • Principle agreements between clients, contractor, consultants and subcontractors need to be in place early. This enables ownership and reward to motivate engagement. Outcome Summary
