I-405 Sepulveda Pass Widening Project

The I-405 Sepulveda Pass Widening Project was a 10-mile highway widening project between the I-10 and SR-101. The purpose of the project was to extend and provide a continuous north and south HOV system. The Project was located in a fully developed urban basin within the City of Los Angeles, a hilly terrain and a sensitive environment. There were 27 bridge modifications and replacements, nine miles of retaining wall, numerous utility relocations, and city street improvements required to provide the highway improvements, all with the added challenge of managing traffic during such a complex project. It was, in the true sense, Design-Build with LA Metro, Caltrans, and local jurisdictional agencies providing over-the-shoulder Reviews.

PQM served as the Design Quality Manager on behalf of HNTB. We prepared the Design Quality Management Plan to meet the contract requirements, and streamline the internal and external processes. PQM implemented the program, provided training for more than 100 people and 15 sub consultants, and conducted surveillance of overĀ 300 submittals to monitor the plan over an 18-month period. Kiewit, LA Metro, and Caltrans mutually agree that this was an extremely effective Design Quality Management Plan.
