Delays in public construction projects execution lead to serious problemas because these projects are planned to provide services to the community and financed by resources from taxpayers, thus, the public project managers must always seek to meet the stipulated execution and construction deadlines. This study objective is to measure the consequences of public constructions delay through the opportunity cost. As a case study it was adopted a Public University construction project aiming at the expansion of a Health Care Center for children with autism sprectrum disorder. The methodology presented applied characteristics with exploratory objectives, using qualitative and quantitative approache. This research aimed to characterize the time delay of the construction project, as well as the services that couldn't be provided, both for the number of attendances that were not performed and for graduate and undergraduate students who coundn't increase their qualification because they coundn't have experience of participating in such project. Through the study, among other things, it was possible to envisage that if autistic children needed to be treated in a private clinic to have similar care they would have to provide approximately R$ 236.50 per session. Another relevant factor is that with the completion of the construction project there would be a 34% increase in the number of services performed from the year 2014 to the year 2018. The result has shown that non-compliance with the deadline of a public construction project is much more damaging than a mere delay in time of the construction and should be avoided or minimized to the maximum extent.

(Universidade Federal do Pará, 2019-07-16) FRANÇA, Alexandra Algélia da Silva; NEVES, Renato Martins das; http://lattes.cnpq.br/6538317425557058; DUARTE, André Augusto Azevedo Montenegro; http://lattes.cnpq.br/1135221873341973
The wish and need of possess a fix dwelling are recurrent on Brazilian families. That require a planning with sacrifices for the family's, the same that should be seriously impacted by the recurring delays on delivery of housing units. The objective is measure monetarily the prejudice or damages adopting opportunity cost to value measure. Two parameters were considered, divided into 3 factors: The first parameter consists of two factors: 1) a physical disease due to the sum of frustrations(psychological disease) named effectiveness cost, 2)The living cost on overtime of property delivery contract to the client wich in theory will have to support two residencies. The second parameter correspond to legal costs that covers the cost of court proceedings and attorney fee cost. Three scenarios were built. : 1°) there is no psychological harm, or will not be considered, there being no cost effectiveness, 2°) damage restricted to one family member and 3 °) psychological damage throughout all the family. In a case study involving a single major construction company, conducted in another well-established research, found that the delay is on average 55.4 months. Being science fragmented in several areas of knowledge, which often do not interact with each other, multidisciplinarity was essential to achieve the proposed objective. It can be concluded that the opportunity cost ranges from R $ 76,371.69 to R $ 383,661.37 in absolute values, ranging from 16.30% to 70.16% of the apartments market value, depending on the scenario.
