1. Construction Quality Management Metro Goldline Eastside Extension Los Angeles January 19, 2007 ASCE Construction Institute Conference

2. The MGLEE Project The MGLEE is a six-mile, dual track light rail transit system extending the Pasadena Gold Line from Union Station to East Los Angeles. This $898 million project consists of elevated guide way, at-grade segments, 1.7 miles of twin tunnels, 2 portals, 6 at-grade stations and 2 underground stations.

4. MGLEE Time Line  Project was initiated in 2001 Environmental & Preliminary Engineering phaseEnvironmental & Preliminary Engineering phase  Final design and contract packaging in 2003  Construction contracts awarded in 2004  Construction currently more than 50% complete  Revenue Operating Date is December of 2009

5. Project Quality Program Requirements  Origins in FTA QA/QC Guidelines  Design/Bid/Build - Tunnels & Station/Portal Excavations Traditional 16 element prescriptive programTraditional 16 element prescriptive program Used on prior LACMTA projects with successUsed on prior LACMTA projects with success Metro wished to maintain direct control of tunneling operationsMetro wished to maintain direct control of tunneling operations  Design/Build – At grade, stations, track work & systems Design-Builder to develop/implement a program consistent with Metro program requirementsDesign-Builder to develop/implement a program consistent with Metro program requirements Use of an existing program tailored to project requirements acceptableUse of an existing program tailored to project requirements acceptable

7. Quality & the Design Development Process Surveillance of the Design Process  LACMTA full participation in inter & intra discipline check & back check processes  Verify compliance with approved Design Control Procedures  Monitor comment tracking and resolution  Periodic Design Surveillance reports to project management

8. Project Oversight and Surveillance Audits  Periodic & Scheduled  “Open Book Test” Philosophy  Single or Multi-Elemental  Full Program Scope Annually  Team Approach Non-IPMO assigned Sr. Quality EngineerNon-IPMO assigned Sr. Quality Engineer Site-Assigned Sr. Construction InspectorSite-Assigned Sr. Construction Inspector Design-Builder’s Quality EngineerDesign-Builder’s Quality Engineer

9. Project Oversight and Surveillance Audits – continued  Enhanced effectiveness  Unbiased & independent assessment  Coupled to Site/Issue Familiarity  Minimizes “adversarial” interaction  Reduced administrative load  Fewer findings/faster resolution  Minimizes staff needs

10. Project Oversight and Surveillance Surveillance  Construction Multiple daily site visitsMultiple daily site visits Keyed to 3 week look-ahead scheduleKeyed to 3 week look-ahead schedule In accordance with:In accordance with: Approved plans and submittals Approved plans and submittals Approved construction work plans (CWP’s) Approved construction work plans (CWP’s) Weekly Surveillance Reports to project managementWeekly Surveillance Reports to project management Includes multiple color digital photographs of work in progress Includes multiple color digital photographs of work in progress

11.  Weekly Surveillance Reports of Work-in-Process Also used for offsite subcontracted work/materialsAlso used for offsite subcontracted work/materials  Provided to Project Management and affected parties  Consistent summary of requirements and work compliance to approved submittals Surveillance Report

12. Surveillance Report Continued  Documents changing status of issues and contractor actions “Daily Diary” approach“Daily Diary” approach  Color digital photographs Helps reader translate narrative into understandable imagesHelps reader translate narrative into understandable images  Permanent electronic record of work progress of work progress

13. Project Oversight & Surveillance Verification Test Plan  Verifies accuracy & effectiveness of Contractor test program & results  Performed by labs under contract to LACMTA  Testing to coincide with contractor’s or thereafter  Performed at RE/PQM discretion & per plan

14. Project Oversight & Surveillance Verification Test Plan – continued  Structural Concrete  NDE of Weldments  Backfilling Operations

15. Summary  An experienced, quality-minded Contractor is key  Place focus on “the few” vs. “the many”  No substitute for interpersonal relationships PartneringPartnering Co-locationCo-location  Benefits: High level of complianceHigh level of compliance Eliminate adversarial interactionsEliminate adversarial interactions Reduced administrative workloadReduced administrative workload Minimized staffingMinimized staffing
