WE EXIST TO BUILD GREAT THINGS DPR Construction UCSF Mission Bay Pre-fabrication Effort Project Background  UCSF Mission Bay Campus –Hospital – 650,000 SF – OSHPD 1 –Outpatient Building – 250,000 SF – OSHPD 1/3 –Energy Center – 20,000 SF  Total Value = $1.68 Billion  Target Budget = $1.58 Billion  UCSF Medical Center at Mission Bay UCSF Medical Center at Mission Bay

WE EXIST TO BUILD GREAT THINGS DPR Construction UCSF Mission Bay Pre-fabrication Effort Scope of Work  Produce fully coordinated models that can be used to create OSHPD submittals for the Hospital / OPB and EC  Preconstruction Services Only  Currently over by $100M and team needs to address this  Use BIM / VDC and Lean Principles

WE EXIST TO BUILD GREAT THINGS DPR Construction UCSF Mission Bay Pre-fabrication Effort Pre-Fabrication  Ideas: –Brain-storming session. Every idea was analyzed –Identified Constraints

WE EXIST TO BUILD GREAT THINGS DPR Construction UCSF Mission Bay Pre-fabrication Effort Pre-Fabrication  Ideas That Work –Industry Standard: Pre-cut Conduit & MC Pre-Punch Panels Pre-fab J-Boxes Trim for Fixtures Bathroom Carriers Pre-Spooled & Jointed Pipe Pre-Section Duct VAV & Attenuator Sections Soffit Drops Box Headers Headwall Units  Ideas that Don’t Work –Pre-Fab Bathrooms Structure Won’t Allow It –Joint Racking OSHPD Won’t Allow It –Pre-Fabbed Electrical Rooms –Med-Gas Rack OSHPD Won’t Allow It

WE EXIST TO BUILD GREAT THINGS DPR Construction UCSF Mission Bay Pre-fabrication Effort Panelized Systems  Prefabrication –Currently performing feasibility analysis. What’s the engineering say? Can it be coordinated? How many panels must be pre- fabbed to break even? How big can they be? Optimal height? Schedule Impact? Where should we target? Etc…?

WE EXIST TO BUILD GREAT THINGS DPR Construction UCSF Mission Bay Pre-fabrication Effort Panelized Systems  Preliminary Research: –Labor Unions –Pre-Fabrication Site –Engineering Requirements –OSHPD Approval –Machine Proposal  Preliminary Answers: –Labor Unions must work locally –Pre-fab site subject to location constraints –Panels can span 8’ and are stronger than traditional walls –OSHPD is OK –Custom Machine can be built

WE EXIST TO BUILD GREAT THINGS DPR Construction UCSF Mission Bay Pre-fabrication Effort Panelized Systems  Hybrid system –Individual Panels –Up to 8’ in length –Target 6” above ceiling –Designed lengths for “layout framing” –Complete with Backing In-wall MEP Top & bottom track

WE EXIST TO BUILD GREAT THINGS DPR Construction UCSF Mission Bay Pre-fabrication Effort Panelized Systems  In-fill –Traditional “stick framing” –King studs, infill above 9’6”

WE EXIST TO BUILD GREAT THINGS DPR Construction UCSF Mission Bay Pre-fabrication Effort Installation Process  Process: 1.Corner, Kong, & Top Track Placed 2.Panels laid in 3.In-fill framing comes behind. 4.Walls inspected and closed.

WE EXIST TO BUILD GREAT THINGS DPR Construction UCSF Mission Bay Pre-fabrication Effort Alternate Installation Process  Process: 1.Corner, Kong, & Top Track Placed 2.In-fill framing. 3.Panels laid in 4.Walls inspected and closed.

WE EXIST TO BUILD GREAT THINGS DPR Construction UCSF Mission Bay Pre-fabrication Effort Target Areas  Identify Repetitive Areas of the Floor Plan  Same Rooms= Repeating Panels  10 Different Panels Used 100x’s  Vs.  100 Panels Used 10x’s

WE EXIST TO BUILD GREAT THINGS DPR Construction UCSF Mission Bay Pre-fabrication Effort Challenges  Models for 3-6 have already been created and coordinated. –30,000SF every 20 days.  Pre-fabrication was not addressed during these phases –Critical studs occur every 4’ in most patient rooms  Schedule Impact –What is the schedule impact? Are we more efficient? What are the productivity rates?  Engineering –Do panels have to match infill above? –How far can we span?

WE EXIST TO BUILD GREAT THINGS DPR Construction UCSF Mission Bay Pre-fabrication Effort Advantages  Quality Control  Productivity Rate  Productivity Tracking  Waste Reduction  Schedule Benefits = Cost Benefits

WE EXIST TO BUILD GREAT THINGS DPR Construction UCSF Mission Bay Pre-fabrication Effort What’s Next  Currently Modeling Critical Studs Prior to Coordination  Subs should be able to coordinate around studs supporting panels.  To
