Following a 2017 mandate, the City of Lake Oswego hired Murraysmith to manage a five-year, multi-million-dollar street improvement program focused on upgrading pavement conditions. Murraysmith is serving as program manager and providing design and construction administration for annual paving and slurry seal projects.
To manage the significant increase in annual workload, Murraysmith teamed with local firms and integrated with City staff to form a long-term program team. To establish a framework integrating City/Consultant staff for ongoing delivery, the Murraysmith team developed a program management plan (PMP) that included right-sized tools, such as a master budget spreadsheet, risk register, public outreach plan, and five-year paving plan. By utilizing these tools and meeting regularly, the program team has managed ongoing needs and successfully tracked progress.
To deliver improvements, Murraysmith has designed and provided construction administration for annual paving projects. The design process involves collaboratively determining pavement rehabilitation treatments with overlays, grind and inlays, full-depth repairs, and full-depth reclamation. Related work includes replacing stormwater catch basins with sumps for improved maintenance, curb ramp retrofits and push button modifications to meet ADA requirements, and new durable pavement markings. In addition to these annual projects, Murraysmith also oversaw two separate full-depth reconstruction capital improvement projects, including other utility upgrades. To provide additional value, a separate contract in 2020 is being completed for crack and slurry seal for low-cost preservation of many residential streets.
In 2020, when the program reaches the 60% complete mark, the team will have replaced 67,000 tons of asphalt, 17 miles of slurry seal, and 185 curb ramps. The Pavement Condition Index (PCI) is anticipated to rise from 68 in 2017 to approximately 74 in 2022.
