The burden of showing evidence of increased costs lies with the contractor. Special rules exist for entitlement to whether or not contractor is entitled to profit in addition to the actual costs they incurred, especially in the cases of leased equipment that was held over due to delays on the part of the Government or the Government's failure to properly integrate other contractors who then interfered with our contractor's work. Cases out there that say the Government can reduce profit if risk was reduced due to the change.
