Analysis of the factors of influence and diagnosis of the management of the residues of the civil construction (RCC) in the construction sites of the city of Recife-PE

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.

摘要：本研究旨在明确RCC产生的影响因素，并对巴西伯南布哥州累西腓市的建筑工地废弃物管理现状开展诊断。本次研究通过访谈及向35处建筑工地的负责人发放问卷的方式收集信息，以此完成影响因素识别工作。研究人员针对其中15处建筑工地实施了废弃物管理现状诊断，通过实地调研明确了其处理所产生废弃物流的具体方法。与RCC产生相关的主要影响因素包括材料过度消耗、工程项目的复杂性与变更，以及所涉及的施工作业流程。针对RCC管理的诊断结果显示，15处建筑工地未完整留存废弃物产生数据；其中8处建筑工地通过了ISO 14001认证，相较于未通过认证的工地，其RCC管理方式更为高效。当前建筑工地普遍缺乏对材料消耗及废弃物产生的认知。开展充分的评估不仅能够助力相关企业优化环境绩效，更有助于企业自身的生存与发展，打造成功的经营项目。
