1 BIM-MEP AUS 2013 FORUM Efficiencies Gained through BIM; from Design to Construction Martin Howland July 26 th, 2013

2 Efficiencies Gained through BIM; From Design to Construction Presentation will consider:- Case Study: Telstra Clayton Data Centre AECOM approach to BIM during Design Team approach to BIM during Construction Measuring, Take-offs & Procurement Efficiencies in Construction Phase Pre-fabrication BIM to Field Future considerations Our thanks to go AG Coombs for their assistance in the preparation of this presentation Page 2

5 AECOM Approach to BIM during Design; Pursuit to a Fully Integrated Workflow AECOM advocates for open standards through design phases AECOM shares model with Contractors to bring efficiencies into the total project Legal issues to be considered The more resolved the BIM model, by Consultant or Contractor, the greater the efficiencies gained Quality of Consultant s model sets the tone for BIM project success BIM-MEP AUS is Educating the Industry Page 5

6 DATA DELIVERABLE AECOM Approach to BIM during Design Non Integrated Integrated Workflow Workflow DESIGN CONSTRUCTION COMMISSIONING DATA DELIVERABLE ASSET TRACKING AND FACILITY MANAGEMENT Page 6

7 OPEN STANDARD IFC/COBie AECOM Approach to BIM during Design Information Exchanges DESIGN PERFORMANCE CONSTRUCTION SUPPLY CHAIN COMMISSIONING DATA RICH 3D MODEL ASSET TRACKING AND FACILITY MANAGEMENT Page 7

9 AECOM Approach to BIM during Design; Design Verification BIM Quality Assurance We use colour to verify parameter contents and fixture placement in printed drawings. Page 9

10 Team Approach to projects in Design / Construction Collaborative behaviours Team Dynamics / Culture Frequent Information Sharing Telstra Data Centre Pilot project; integrated design office Architects / Engineers stationed together Highest possible levels of collaboration Page 10

11 Efficiencies in Construction Phase For Telstra & other projects, BIM Design Model shared with Contractors at completion of Design. More of these. Bringing efficiencies to the contractor in; Measuring, take-offs, procurement Shop drawing processes Pre-fabrication BIM to Field Bringing efficiencies to the consultant and client in; Reduced RFIs Less variations Less of these. RFI s; NEC NDC Mech Elec Fire Hyd Page 11

12 Efficiencies in Construction Phase; Measuring, Take-offs & Procurement For Telstra, contractor used the AECOM model for direct take-off of pipework quantities exported to Procurement Schedules. Procurement schedules issued directly to pipework vendors allowing; Confidence in quantities measured and scheduled Vendor pricing based on schedules Competitive tendering to multiple vendors No contingency priced into tenders Page 12

13 Efficiencies in Construction Phase; Shop Drawing Process Design Model For Telstra & other AECOM projects, contractor used the design model as basis for production of workshop drawings; Conversion to BMA format and final coordination for construction and fabrication models Large portions of shop drawings requiring little or no re-draw Construction Model Often seeing little variation in workshop drawing layouts as compared to design layouts Page 13

18 Efficiencies in Construction Phase; Pre-Fabrication Sub-contractor s greatest efficiency in Construction processes unlocked by BIM is Pre-fabrication. Advantages include; Reduced OH&S Site risk (Safety - $$) Virtual construction & planning (Time - $$) Reduced site disruption / program(time - $$) Improved quality in construction (Quality - $$) Simultaneous Build / program (Time - $$) Page 18

20 Efficiencies in Construction Phase; BIM to Field Efficiency being translated from model to site through rapidly advancing technologies; Trimble Robotic Point Positioning Digital site coordination Tablet viewers on-site Primarily mechanical as lead services coordinator although electrical contractors now also employing these technologies.

25 Future Considerations More movement towards As-Built BIM models to bring further benefit to client through life of asset. Awareness at contract stage for Arch & Struct models to be updated through construction. Contractors starting to see benefits of BIM for their own project productivity and profitability Reduced tender pricing for BIM projects, as compared to non-bim Faster development of seamless software interfaces between engineering and modelling platforms. e.g. AutoDesk to IES Virtual Environment Consultants get to see more benefit; full potential yet to be realised Page 25
