TAIT & Associates, Inc. t. �p:3 WL' °' On -Call Engineering Services Dimension Drive, Civic Center Drive, & Portola Parkway Rehabilitation Lake Forest, CA TAIT was selected by the City of Lake Forest to provide civil engineering and surveying on a citywide arterial design project which included the design of the following three segments: Dimension Drive from Bake Parkway to Lake Forest Drive; Civic Center Drive from Enterprise way to South End; and Portola Parkway at SR-73 Overcrossing (w/in Caltrans R/W). The project encompassed a total of 6,400 linear feet of arterial/collector roadways and included full depth reconstruction of dimension drive and Civil Center drive and a 2" grind and overlay of Portola Parkway within the Caltrans R/W limits. This project required obtaining a Caltrans encroachment permit for both construction and traffic control purposes. As a result, further detail and scrutiny was required on the design to ensure Caltrans acceptance of the traffic control system as well as the overall design materials and elevations. TAIT was designated the lead consultant to compile all plans and prepare the required final technical specifications and bid documents in order to capture the required scope of work and design elements. Jacaranda Neighborhood Rehabilitation & Sewer Replacement Project Fullerton, CA TAIT was selected by the City of Fullerton to provide civil engineering services for the Jacaranda Neighborhood Pavement Rehabilitation and Sewer Main Replacement Project. The project was located in a historic neighborhood in the City of Fullerton that included over a mile of residential roadway rehabilitation and 2,700 linear feet of sewer main replacement within the neighborhood surrounding Jacaranda Place from the western cul- de-sac to Malden Avenue. In addition to roadway reconstruction and grind and overlay operations, the roadway component of the project included the removal and replacement of over 1.5 miles of old, deteriorated, and uneven curb and driveways throughout the neighborhood with new variable height curb and gutter in order to engineer and define the roadway drainage conditions within the neighborhood. Due to the historic and unique nature of the neighborhood, the curb heights and flowline were carefully profiled in order to improve the drainage conditions while also joining the existing pavement. In addition to the roadway improvements, TAIT was also tasked with the abandonment of two old sewer siphon systems and the combination and construction of a single master neighborhood sewer siphon along with the removal and replacement of 2,700 linear feet of existing 6" VCP with new 8" VCP sewer. The sewer siphon was design to convey sewerflows under an existing Orange County Flood Control Channel and required the design of a double barrel sewer siphon that was installed via jack and bore method.
