Chino Hills Parkway & Chino Avenue Street Rehabilitation Project
OE provided construction management and inspection services to the City of Diamond Bar for this STPL-funded project. The site spanned 1.25 miles along Chino Hills Parkway, from the north city limit to the south city limit, and Chino Avenue, from Chino Hills Parkway to the eastern city limit. The scope included grind and ARHM overlay, 783 SF of local R&R, and minimal PCC curb, gutter, and sidewalk replacements. OE conducted a constructability review prior to construction commencing, and noted several additional reconstruction areas along with several ramp upgrades to add to the scope. In addition, paving was coordinated to be completed at night to minimize traffic congestion.
