Accuform Signs, a maker of industrial safety signs, plans to add 271 jobs and nearly double the size of its Brooksville workforce to more than 500 with a new 304,000-square-foot facility in the industrial park at the Hernando County Airport. Aided by state industrial incentives, the company is expected to spend $15 million to build and equip the new manufacturing facility on a 40-acre parcel of airport-owned land. Construction is expected to be completed in early 2014. The incentives are based on creating jobs that pay at or above the county's average annual wage of $28,894. Until Thursday's news conference, the unidentified company had been referred to only as "Project Kodiak." Accuform began as a small operation in Pasco County in 1976, later expanding to Brooksville.
