I-15 Express Lanes Project

 As owner's peer review representative, A/E Tech LLC conducted QA/QC of the consultant's noise study for the project corridor. In this capacity, our firm provided technical review and oversight in preparation of the traffic Noise Study Report and the Noise Abatement Decision Report for expressway lanes additions to an approximately 14-mile stretch of the Interstate 15 in San Bernardino and Riverside Counties. The work included detailed review of field noise measurements, review of noise modeling work in TNM to evaluate impacts, and collaborating with the consultant team to evaluate acoustical feasibility and reasonableness of soundwalls throughout the project corridor.
