(2025) In an analysis of 65 PLA and 248 Non-PLA Public Works Construction Projects in Sacramento County, California between 2019 – 2023, researchers from NorCal Construction Industry Compliance, Alma College and the Illinois Economic Policy Institute have found that PLAs are associated with 15-17% faster completion times than non-PLA projects.
Shorter timelines can reduce overall costs by lowering labor expenses and avoiding costs tied to stopping and restarting work. Faster completion also has broader social and economic benefits, such as quicker access to improved infrastructure like schools, roads, and water treatment facilities. Delays in public works can have ripple effects, including productivity losses from longer
transportation times and delayed services. Overall, the findings highlight that construction and workforce policies like PLAs can significantly affect both project efficiency and community well-being.
