This is an Independent Site Assessment (ISA) document for the City of Pasadena prepared on March 12, 2019, concerning the Holly Street Bridge Seismic Retrofit and Rehabilitation Project. The assessment documents the existing conditions and environmental baseline of the Holly Street Bridge site, which is located in Pasadena, California. The ISA provides a comprehensive evaluation of the site's current state prior to commencement of construction activities, establishing a baseline for environmental and structural conditions that will inform project planning and management. The document serves as a foundational reference for the construction management consultant who will oversee and manage all construction activities related to the seismic retrofit and rehabilitation work. The site assessment addresses physical characteristics, accessibility, existing infrastructure conditions, and other relevant site-specific factors necessary for effective project execution and compliance with federal requirements under the Highway Bridge Program administered by Caltrans.

The ISA establishes critical baseline information that the selected construction management consultant will utilize throughout the project lifecycle. This assessment is essential for the consultant's on-site inspection services and construction oversight responsibilities, enabling proper documentation of existing conditions against which work progress and compliance can be measured. The document supports the consultant's role in managing construction materials testing, coordinating day-to-day construction operations, and ensuring adherence to federal funding requirements. As a federally funded project through Caltrans' Highway Bridge Program, the ISA provides the environmental and physical baseline necessary for regulatory compliance and project documentation throughout the retrofit and rehabilitation process.
