If the living wage increases during the term of a contract, can the contractors submit a request for a contract price increase?
No. Bidders/Offerors typically have to project inflation costs over the term of multi-year contracts; this is simply another situation of when they will have to do that. Moreover, if a contract includes a provision for price revision based upon changes in the Consumer Price Index (CPI), since changes in the living wage are indexed to changes in the CPI, a CPI adjustment would automatically allow for recouping some/all of the living wage adjustment.
