Electricians working on the recently opened FBI office in Kapolei are owed $319,939 in back wages, according to the Wage and Hour Division of the U.S. Department of Labor.

The division found that California-based subcontractor RMA Land Construction Inc. and its subcontractor, isle-based RB Electric, failed to pay proper prevailing wages, as well as overtime to 48 electricians involved in the project.

“Employees on federally funded construction projects must be paid at least the occupational prevailing wages associated with their work and also stipulated in the prime contract,” said Terence Trotter, district director in Hawaii. Penrose/Walsh FBI Honolulu LLC was the prime contractor at the site.

The building itself, designed by Architects Hawaii Ltd., was honored in May with an Overall Grand Award at an annual Building Industry Association Renaissance Awards.
