I am a supporting an acquisition for security system maintenance and equipment installation, as a consultant, which the Agency has determined is subject to the Service Contract Act and DOL wage determinations. The Agency has modified the SCA Directory of Occupations 5th Edition labor category descriptions for those positions covered under the wage determination to include a minimum number of years experience and/or technical training requirements. For example, for 23181 Electronics Technician Maintenance I the Agency has added a requirement for a minimum of 1 plus years of equivalent technical experience and/or military technical training, Level II 3 plus years of equivalent technical experience and/or military technical training, and Level III 5 plus years of equivalent technical experience and/or military technical training. Is this an acceptable practice? I haven’t been able to find anything in my research that specifically precludes an Agency from modifying the description. I called DOL Wage and Hour Division last week and left a message however no one has returned the call. If anyone has a reference which supports/does not support this practice, it would be greatly appreciated.
