Khanzadi et al (2019) further emphasize the complexity of the processes related to the projects, highlighting the various existing interconnected jobs as well as their variability and unpredictability, and that would bring about variations and delays found in the schedules.…”

“…Estes dados ficam abaixo dos estudos encontrados, apesar de serem de períodos diferentes, aplicando a média nos dados apresentados porCoutinho (2010) no trabalho desenvolvido nas obras de 2006 a 2009 tem-se um percentual de atraso de 59,81% para a UFPA e 71,38% para a FADESP. Já o trabalho deSantos et al (2014), em uma autarquia municipal no período de 2009 a 2013, 96% tiveram aditivo de prazo e que o tempo em média foi acrescido de 111% do previsto incialmente.…”
