Swinerton Management & Consulting (SMC) was selected in May 2018 to provide Construction Management and Inspection Services by the City of Orinda for the joint paving project between the City of Orinda and the Town of Moraga. This $15 million pavement rehabilitation project included pavement improvements to over 60 street segments throughout Orinda and three streets in Moraga. The project scope of work also included storm drain improvements, featuring cured-in-place-pipe (CIPP), minor concrete improvements, AC dikes, AC swales, and street monument verification. The SMC team is now completing the close-out and working with the Contractor and the City to complete the punch list items.
The Pavement Rehabilitation consisted of Full Depth Reclamation (FDR), base repairs (“digouts”), and overlays. FDR is a process of pulverizing the existing roadway with a portion of its subbase to create a stronger subbase for the new pavement. Cement is added to the pulverized material to provide more strength and stability. Once the new subbase is cured (3-5 days), new pavement can be laid. Regular hot mix asphalt (HMA) was used on most of the streets in Orinda and rubber hot mix asphalt (RHMA) was used on about a dozen streets (including the three streets in Moraga).
The 7-month project was fast-paced with potholing (verifying existing utilities), storm drain improvements, concrete work, adjusting existing utilities, pulverizing roadway, cement treatment, and paving all being done concurrently, at various locations throughout Orinda and Moraga. The SMC team needed to closely observe all aspects of the project to ensure the work was in compliance with the Special Provisions and Caltrans Standard Specifications so that the City of Orinda and Town of Moraga receive a high-quality project.
