3 Agenda Project Overview Subcontractor Profiles Project BIM Costs Pre Fabrication 4D Scheduling Trade Coordination (Change Management) Social Interaction Design Team Perspective Where do the savings go?

4 The Project -Arizona State University ISTB IV ISTB IV is a $113 million research laboratory delivered by CM@R. Because of prior relationships, the Construction Manager (Sundt Construction) and Design Team (HDR) managed the project more like an IPD than CM@R, allowing for more open communication and sharing of information. Trade subcontractors were shortlisted prior to bid based on their ability to utilize BIM and to maximize prefabrication. The project is currently 85% Complete.

5 Project Complexity

6 Project Timeline Contract Awarded 08/2007 Subcontractors Selected 10/2007 Design Coordination Begins 11/2007 Trade Coordination Begins 08/2008 Project Delay 02/2009 to 11/2009 New GMP in Today s $ 11/2009 to 03/2010 Notice to Proceed 03/2010 New Trade Coordination begins 03/2010 Level 4 Trade Coordination Complete 12/2010 Scientists Selected (End User) 04/2011 Simon Says STOP Scientist Specific Equipment Selected 07/2011

7 Unique Characteristics Designer and GC have good prior work relationships (Non official IPD relationship)

8 Unique Characteristics Original budget for project was $134M, reduced to $110M in Value Engineering. Currently at $113M with additional scope 280,000 Total SF 145,000 SF Lab Space Subcontractors Shortlisted based on BIM experience and ability to Prefabricate Subcontractors were hard bid prior to delay, converted to GMP after delay to facilitate budget Scientist equipment selection for Level 4 occurred 7 months after completion of trade Coordination for Level 4

9 Subcontractor Profiles Subcontractor Sundt Concrete RCI Systems (Fire Protection) Dynamic Systems (Mechanical and Plumbing) Wilson Electric Percent of Projects Utilizing BIM Company BIM Benefits 80 % Better work planning and execution 40 % Major increase in accountability of trades in coordination 100 % Space Management and coordination with other trades 35 % Resolving constructability conflicts in the virtual world

10 We are talking BIM Money, Money, Money Subcontractor Contract Value Estimated Costs for BIM (All Costs) Sundt Construction (GC) $63,310 Sundt Concrete $12,625,532 $55,000 RCI Systems (Fire Protection) Dynamic Systems (Mechanical and Plumbing) $1,019,450 $14,500 $27,000,000 $0 (Included in Standard Labor Factors) Wilson Electric $16,674,659 $51,204 Additional Non-estimated BIM Costs $40,000 Totals $57,319,641 $324,014 Assumes $100K for M,P

11 The real cost of BIM - $324,014 BIM Costs to... Percentage Contract Values of Parties Involved with BIM.6 % Total Contract Value.3 % Total Contract BIM Costs Cleaning Costs

12 Pre - Fabrication Components Percent Prefabricated Ductwork 100 % Piping 30 % Fire Protection 90 % Electrical 5 % Schedule Savings due to pre-fabrication = 16 Weeks Weekly General Conditions = $125, Weeks X $125,000 = $2,000,000 Savings

13 4D Scheduling yea right Due to budget constraints, full time scheduler was removed from General Conditions Sundt utilizes the Last Planner System for Scheduling Project Superintendent develops Baseline Schedule Subcontractors in conjunction with Superintendent perform Pull Planning sessions for each milestone activity to create detailed activity schedules Superintendent adds detail to CPM MEP Engineer links CPM to Model

14 4D Scheduling yea right Average of 16 man-hours per milestone to link CPM to Model 63 Distinct Construction Milestones 63 x 16 = 1,008 Man-hours (25 weeks - $38,000) 4D Effort doesn t keep up with project Too much effort for amount of payback Frustrated MEP Engineer

15 4D Scheduling Different way to look at things Every time someone says BIM Model, a cute fluffy kitty dies. Every time someone says BIM Model, a coyote has lunch.

16 3.5D Versus 4D Getting Some Benefit Use Model as Pull Planning Tool Less than an hour Per Milestone 63 Distinct Construction Milestones 63 Man-hours (1.5 weeks - $2,200) Minimal Effort Maximum Payback Happy MEP Engineer

17 Trade Coordination Change Management Coordination Effort is Here Einstein is Hired and Makes Changes Here

18 Trade Coordination Change Management Subcontractor Change Order Values to Date (E&O and Contingency) Sundt Concrete $0.00 RCI Systems (Fire Protection) $0.00 Dynamic Systems (Mechanical and Plumbing) $84, Wilson Electric $0.00 Other Subcontractors and issues $904,685 Total $989,135

19 Change Management Project Comparison Project Construction Contract Value Change Orders (E&O and Cont.) Percent of Contract ASU BIO 1 $49,793,546 $3,654, % ASU BIO 2 $52,029,178 $3,616, % Average $50,911,362 $3,635, %

20 Change Management Project Comparison Project Average of BIO 1 & 2 Anticipated ISTB IV based on History Actual ISTB IV to Date Change Order Reduction Construction Contract Value Percent of Contract Change Orders $50,911, % $3,635,393 $112,600, % $7,994,600 $112,600, % $989,135 $7,005,465

21 The Social Value of BIM To be social is to be forgiving Robert Frost The value of a dollar is social, as it is created by society Ralph Waldo Emerson How am I ever going to quantify The Social Value of BIM? Dan Russell

22 The Social Value of BIM Relationships Ease of doing pull planning sessions Mike Jackson, Senior Superintendent, Sundt Owner s confidence in design and construction team Mike Hill, Senior PM, Sundt Things just went right, no bad phone calls or anything Ryan Rogers, PM Sundt Concrete It has been a positive experience that helped team communications Brian Wieneke, PM Dynamic Systems Major advantage is access, major disadvantage is access Tom Gorman, PM Wilson Electric

23 Designer Perspective of Project BIM Provides a pure understanding of a 3D world Complex area communication between design, construction, and users Decisions made based on BIM reviews vs. Construction Documents Model used to show how ASU standards wouldn t work on this project in some cases Early communication reduces RFI s and construction administration Modeling of access zones allows for increased coordination Will the 7 th floor work? Because of BIM coordination, yes it will! Inclusion of embeds and unistrut solved multiple issues

24 Designer Perspective of Project BIM Sometimes too reliant on BIM Differences between BIM and Design Documents created some issues

25 Project Savings Costs / (Savings) Project BIM Costs $ 324,014 Schedule Savings due to Pre-fabrication ($ 2,000,000) Change Order Reduction ($ 7,005,465) Additional Design costs $ 0,00 Total ($ 8,681,451) So where do the savings go?

26 Is it fair that the savings goes back to the Owner? We are OK with us making a fee for the work we do. As long as we get a fair profit, the owner deserves to get the best building at the best price Mike Hill, Senior PM, Sundt

27 Is it fair that the savings goes back to the Owner? No issue with cost savings returned to the owner Should be shared so there is an incentive to save rather than just making sure that you don t go over the GMP total I believe for a GMP to work the best, there should be an incentive for the Subcontractor to finish under budget If the owner gets all of the savings, then they will trust us to do their next project Subcontractors
