However, evidence indicates that EVM is not typically implemented by contractors when the payment agreement is based on unit-prices. In this payment approach, the owner pays the quantities actually executed according to the preagreed rate established in the contract for each unit or task; the income received by the contractor from the owner (generally named production) is neither proportional to costs nor fixed a priori, as in cost-reimbursable and lump sum contracts, respectively. Therefore, contractors have to control not only cost but also production. The current formulation of EVM does not allow controlling production; an additional baseline is needed. In response, this paper presents a proposal for adapting EVM to contractors when using the unit-prices payment agreement. Using a case study ...
