Erich Thalheimer, BSME, INCE Bd. Cert., Acoustical Engineer

Mr. Thalheimer is nationally renowned for his work on construction noise control and policy development.  He has managed and advised on numerous controversial multi-million and multi-billion dollar projects in order to strike a balance between the contractor's need to advance the work and the community's needs for peace and quiet.

For ten years he served as the in-house technical manager for the construction noise control program at the Central Artery/Tunnel Project (The Big Dig) in Boston. Based on this success, Mr. Thalheimer was asked to join a team assembled by the Federal Highway Administration (FHWA) tasked with updating FHWA's national construction noise policy and prediction model. This work resulted in the new FHWA Roadway Constructing Noise Model (RCNM). In a similar manner, Mr. Thalheimer was also retained to assist the New York City Dept. of Environmental Protection to assist in developing and updating NYC's Construction Noise Regulations. These new rules went into effect in July 2007.  He will be giving a plenary speech to describe the work that went into the NYC noise regulations at the InterNoise 2012 Conference in New York City . 

Based on his recognized expertise, Mr. Thalheimer recently served as Chairman for a special Construction Noise session at NoiseCon 2010. Mr. Thalheimer's construction noise-related work was cited as a positive example in the new textbook, Technology for a Quieter America, published by the National Academy of Engineering in 2010.

 

Some of the more notable construction noise projects that Mr. Thalheimer has been involved with include the following:


  • LaGuardia Airport Redevelopment Project, Skanska/Walsh JV, New York City, NY (2016) – As part of a joint venture design-build team, performed ambient noise and vibration measurements at eight community receptor locations surrounding LaGuardia Airport, and developed project-wide Construction Noise and Vibration Monitoring and Mitigation Plan.

  • I-25/I-225 T-Rex Project, Kiewit Group, Denver, CO (2001) – The T-Rex Project, at $1.67 billion, is the largest infrastructure project ever awarded in the state of Colorado.  Working for the Design-Build Contractor, a crucial noise variance was successfully crafted and presented to the Denver Board of Environmental Health to allow nighttime construction operations. The variance proposed self-imposed nighttime noise limits, the use of permanent and temporary noise barriers, the use of quieter-type backup alarms, equipment and time restrictions, and temporary hotel accommodations (3 nights) for residents within certain noise eligibility zones during noisy bridge demolition activates.  The variance was approved, and was extended a year later based on the successful implementation of the T-Rex project’s noise control program during its first year.
