LOCATION: Los Angeles, CA
PROJECT TYPE: Construction Noise & Vibration Monitoring
CLIENT: Kleinfelder/Metro
CONSTRUCTION YEAR: 2014 - Ongoing

CSDA is working with Kleinfelder/Metro as the acoustical engineer for the
construction of the Purple Line extension. The scope includes:

  • Review of contractor’s RFIs and submittals with respect to construction noise control
  • Review of contractor’s noise monitoring plans and reports
  • Preparation of monthly noise monitoring reports for monitoring conducted by Metro/Kleinfelder
  • Site-specific construction noise and vibration analysis (e.g., Saban Theatre)
  • Ambient noise monitoring at sensitive receivers
  • Data analysis
  • Design of construction mitigation measures

Continuing from the current terminus of the Metro Purple Line at Wilshire/Western,
the Purple Line Extension will be completely underground and extend westward for
about nine miles along Wilshire Boulevard with seven new stations. It will provide
a high-capacity, high-speed, dependable alternative for those traveling to and from
LA’s “second downtown,” including destinations such as Miracle Mile, Beverly Hills,
Century City, and Westwood.
