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

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.

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

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

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

 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

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

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
