Abstract This article aims to identify the factors of influence of the RCC generation, as well as to diagnose waste management at construction sites in the city of Recife-PE. The identification of the factors of influence occurred through the collection of information through interviews and the application of questionnaires with those responsible for 35 construction sites. In 15 construction sites, a diagnosis of waste management was carried out, physically identifying the methods used to manage the generated waste streams. The influencing factors indicated as main aspects related to the RCC generation, the overconsumption of materials, complexity and alteration in the projects, besides the constructive processes involved. The diagnosis made on the management of RCC showed that 15 construction sites did not have complete waste generation data; 8 construction sites had ISO 14001 certification, and these had a more effective way of managing RCCs to those that were not certified. There is a lack of knowledge about the consumption of materials and the production of waste inside the construction sites. An adequate evaluation will allow a better performance of these companies, not only in the environmental aspect but also in the survival of the same companies, creating successful ventures.
