An advance notice of public rulemaking was recently released by the OFCCP requesting input on the development of a system to capture federal contractor salary information.  The notice states that the purpose is to assist with efforts to prevent salary discrimination. Comments must be submitted by October 11, 2011.
 This system would only apply to contractors with more 50 employees and $50,000 in federal contracts.  It would not apply to construction firms, but it would apply to other types of federal contractors. 

While the system and the rule are far from being implemented, the volume and types of information being requested make it appear this would be quite onerous. Much of the information requested might not be easily available, and if implemented this would likely be a difficult and expensive requirement for some contractors to comply with.
