Key Project Changes to Address Stakeholder Comments Key Changes
a) Modified US-101 bridge piles at abutments from driven to CIDH to reduce noise impacts b) Modified design of Center Street Bridge to address City comments regarding safety c) Added tunnel under track section for Metro maintenance/emergency access to Red/Purple Line portal trench d) Modernized Platform 4 canopy design e) Implemented ADA improvements along Commercial Street to address City comments
CMGC Opportunities
Modified 35% design for CMGC RFP and provided additional design details not typically provided at 35% to provide better starting point for contractor to review and make VE and constructability recommendations. 30

POTENTIAL IMPACTS MITIGATION Noise from increased train activity
(Currently 233 Metrolink and Amtrak trains enter and leave Union Station, including empty trains to Central Maintenance Facility)
(830 Metrolink, Amtrak, and future High Speed Rail trains is projected to enter and leave Union Station)
Sound wall up to 22 feet tall to mitigate the impacts to less than significant level.
the sound wall – 62dB 33

the William Mead Homes in the early morning hours had a noise level over 90 dBA.
Council District 1, Metro is working with City of LA, Metrolink and CPUC on the implementation of the first quiet zone in City of LA. Over 120 trains cross N Main Street every weekday, starting at around 4am and sounding the train horns

Benefits of BIM
Risk Reduction
a. Find Coordination and Construction phasing issues in office rather than in field
Better Inform and Support Cost Estimation
a. Quantities can be dynamically pulled from models and trended over the design lifecycle
Automation of Plan Production from Model
compared to traditional 2D plan production due to dynamic and parametric setup
Enhanced Coordination
a. BIM Models provide effective ways to communicate and coordinate design among multiple stakeholders 542
55
BIM Roles and Responsibilities
