1.7 miles of twin tunnels, 2 portals, 6 at-grade stations
and 2 underground stations.
MGLEE Alignment
MGLEE Time Line
Project was initiated in 2001
• Environmental & Preliminary Engineering phase
Final design and contract packaging in 2003
Construction contracts awarded in 2004

Project Quality Program Requirements
Origins in FTA QA/QC Guidelines
Design/Bid/Build - Tunnels & Station/Portal Excavations
• Traditional 16 element prescriptive program
• Used on prior LACMTA projects with success
• Metro 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 requirements
• Use of an existing program tailored to project requirements
acceptable

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
Project Oversight & Surveillance
