Metric to English Conversion California Bridge Construction Forum March 8, 2006 Mark Leja, Chief, Division of Design California Department of Transportation

History  1988 Federal law passed to support metric  1991 FHWA say metric by 1996 or no federal funds  1993 Department decides to go metric  1995 FHWA extends the deadline  1996 Department fully metric

History  2001 FHWA makes metric optional  2003 National Survey – most states have gone back to English  2004 Customer survey – AGC, CELSOC, Local Agencies  July 2004 Decision to go back to English  March year transition plan finalized

Current Status  Converting Design Manuals and Guidance. Some will remain as dual units.  Mapping in English on new projects.  Finalizing Standard Plans and Specifications in English. Available June 2006.

Future Plans  Begin advertising English projects in Summer 2007  Complete Metric projects  Generally English only 2010 and beyond. Rare exceptions may linger (e.g. mega projects).

Innovative Contracting Methods California Bridge Construction Forum March 8, 2006 Mark Leja, Chief, Division of Design California Department of Transportation

Traditional Project Delivery  Design-Bid-Build (DBB)  Specified by Public Contract Code  Design must be complete  Awarded to the lowest responsible bidder

Design-Bid-Build (DBB)  Advantages – well established and widely understood  Disadvantages – perceived as slow and adversarial

Design-Sequencing  A method of contracting that permits each construction phase to commence when design for that phase is complete, instead of requiring design for the entire project to be completed.  Project can be awarded at 30% design.  Awarded to lowest responsible bidder.

Design-Sequencing  Two-Phase Pilot Program underway  Requires annual status report to Legislature  Requires a Peer Review Committee – AGC is a member  Sunset date January 1, 2010

Pilot Program Status  Phase I began 2000  10 projects selected in 5 districts and 9 counties  7 projects constructed (4 projects completely closed out)  3 projects in construction

Completed 03-Sac-80/51Construct Westbound Lane 04-Ala/SCl-680Construct Interim Southbound HOV Lane 04-CC-680Add HOV Lanes 04-Sol-80Stabilize Landslide 07-LA-210Construct Soundwall 07-LA /101 Interchange, Construct Northbound Auxiliary Lane 08-SBd-15Widen Freeway Construction 08-Riv-215Realign and Widen 11-SD-15*Widen Freeway and Install Moveable Barrier (Phases 1-4) 11-SD-905Construct Interchange *Multiple phases (treated as one pilot project) Current Pilot Projects (Design-Sequencing)

Initial Findings  Average Time Savings 4 months  Capital Cost at award similar to DBB (Engineer’s Estimate vs. Low Bid)  Capital Cost Growth similar to DBB (Awarded amount vs. Final Cost)  Support Cost 2-6% greater for Design- Sequencing

Lessons Learned  Document Control is important  Award with first phase 100% complete  Less suitable for large, complex projects

Future of Design-Sequencing  Monitor current projects  Apply lessons learned to Phase II  SB 1210 authorized Phase II Pilot (4 projects selected and in design)  Peer Review Committee continues  Annual Reports to the Legislature

Design-Build An innovative contracting method where a contract for both the design and construction of a project is awarded to a single entity.

Design-Build Nationwide  27 States have used Design-Build  Numerous Cities, Counties and Transit Agencies  Authorized by Federal Highway Administration

Design-Build in California Who has the authority to use it?  Specified Cities and Counties  Schools (K-12, Specified Community Colleges, UC and CSU)  Transit Authorities

Design-Build in California Transportation Projects  Garden Grove (SR-22) HOV Lanes  Southbay Expressway (SR-125)  Alameda Corridor  91 Express Lanes  Orange County Toll Road projects (San Joaquin Hills, Foothill, Eastern, and Glenwood Pacific Interchange)

Design-Build in California Legislative update  SB 1026 (I-405 HOV project) Effective January 1, 2007  AB 1838 (Strategic Growth Plan)  AB 2025 (Niello’s proposed bill)
