Eighteen construction projects have been selected for Business Journal’s 10th annual Top Projects in the North Bay awards.

The editorial staff chose these projects from close to 50 nominations from across the North Bay.

The winning endeavors stretched across the construction spectrum, from cavernous distribution warehouses in Solano and Napa counties to logistics of traffic-stopping work on one of the Bay Area’s busiest spans. The jobs brought together ingenuity in adaptive reuse of a high-rise downtown telephone switch building as high-end offices, a former wine warehouse as a multisport entertainment venues and a shuttered hospital as a homeless youth center.

The projects will be recognized at an awards gala in Petaluma on Dec. 17. Here are the top projects for 2015, by category:
