RESUMO: O impacto ambiental causado pela produção e descarte de resíduos da indústria da construção civil é um dos principais do planeta, seja pela quantidade descartada diariamente ou pelo uso irracional das jazidas de recursos naturais. Este estudo buscou investigar a gestão dos resíduos da construção civil em Teresina – Piauí e envolveu levantamento bibliográfico e pesquisa de campo que foi realizada através da aplicação de questionários, visitas a canteiros da obra de construtoras, empresas terceirizadas atuantes na coleta de entulhos de construção civil e entrevista aos órgãos de fiscalização. A aplicação dos questionários trouxe como resultados, a quantidade de empresas atuantes no município, a quantidade de resíduos produzidos pelas empresas construtoras, suas composições e a destinação final dada pelas empresas recolhedoras. A verificação quanto à atuação dos órgãos públicos responsáveis pela fiscalização e gerenciamento dos resíduos de construção e demolição, mostrou que esta não ocorre de forma regular e que o mais comum é apenas mediante denúncias. A gestão dos resíduos da construção nos canteiros de obra de Teresina é ainda bastante falha com adoção de práticas não eficazes para a amenização do impacto ambiental causado por esses resíduos, sendo bastante deficiente em relação à destinação final adequada.  O intuito do estudo foi investigar o sistema de gestão de resíduos da construção civil em Teresina – Piauí.ABSTRACT: The environmental impact caused by the production and disposal of waste from the construction industry is one of the main issues on the planet, either by the quantity discarded daily or by the irrational use of natural resource deposits. This study sought to investigate the management of construction waste in Teresina - Piauí and involved a bibliographical survey and field research that was carried out through the application of questionnaires, visits to construction sites of contractors, outsourced companies involved in the collection of civil construction debris and interview the supervisory bodies. The application of the questionnaires resulted in the number of companies operating in the municipality, the amount of waste produced by the construction companies, their composition and the final destination given by the collecting companies. The verification of the performance of the public agencies responsible for the supervision and management of construction and demolition wastes has shown that this does not occur regularly and that the most common is only through complaints. The management of construction waste at Teresina's construction sites is still quite flawed with the adoption of ineffective practices for mitigating the environmental impact caused by these wastes and is quite deficient in relation to the final destination. The purpose of the study was to investigate the waste management system of the construction industry in Teresina – Piauí.

The problems arising from construction and demolition waste have always been in our country. The civil construction industry is the sector that generates the most waste that impacts society and is the one that consumes the most raw materials. As a result, it is necessary and extremely important that there is a sustainable management of construction waste. The irregular dispositions of these residues cause many negative impacts to the environment, since they are often thrown in vacant lots, permanent preservation areas, roads and public places, harming the quality of life of the population. Recycling can generate a significant economic advantage in relation to the final destination both in regular deposits and mainly in relation to the irregular ones that cause so much damage to the environment. This study sought to collect information on the current situation on construction waste. And in order to be developed, the present work used bibliographic research in books, specialized magazines, periodicals, and electronic media. Concluding in the final considerations, in which vital points of the research are presented followed by the stimulations the continuity of the studies and the reflections on the generation of solid residues in the civil construction.

Area Of Concern

Construction industry in Malaysia is growing rapidly with high demand due to vast development and urbanization. Therefore, many commercial and residential buildings are being developed. The increasing number of construction projects in Malaysia will indirectly contribute to the increase of construction waste generation. Thus, waste minimization is an important area of concern in the implementation of the construction waste management in the construction industry of Malaysia. Data collection and observations was conducted at three construction sites which adopt different type of method with different type of building and size of project in Klang Valley. The calculation of the construction waste index generated at these sites is adopted from Poon et al., (2001). Result showed that construction method, size of projects (GFA), type of building, storage method system, human error and technical problem can affect the amount of waste index (debris) and amount of wastage level generated at construction sites. Therefore waste index and wastage level can be used as operational an indicator for waste minimization of the construction activities.

Safety And Health

The construction industry is globally known as one of the most hazardous workplaces. Companies in the construction sector are undeniably often focused on completing projects on time, which results in tight work schedules and increases the risks of regular construction site activities, especially for the public who lives in the area. Inadequate rules and regulations in public safety and construction sites not practicing the safety practices to protect the public from harm are potential to cause public accidents to happen. Additionally, little improvement in safety practices at the construction sites and lack of awareness in implementing proper safety practices at a construction site could cause the increasing the rate of public accidents too. This study merely aims to explore the safety practices to be implemented at a construction site in a way to prevent public accidents from occurring. In order to achieve the aim, this study has two (2) objectives; 1: to determine the experience in handling accident cases involving the public at a construction site, and, objective 2: to explore the safety practices to be implemented at the construction site. For this preliminary survey, the qualitative research design was selected and the total number of five (5) professional individuals specialized in safety and health in construction sites were chosen as interviewees based on their experiences in handling public safety issues in construction sites. The results show the most recommended safety practices that need to be implemented which is barricade all entrances and exits of the construction site to prevent access from the public. This study provides good insights to the Department of Occupational Safety and Health (DOSH), National Institute of Occupational Safety and Health (NIOSH), and Construction Industry Development Board (CIDB) in identifying the need for safety practices to prevent public accidents at the construction site in congested urban areas.

AbstractThe construction industry in India is the country’s second largest industrial sector, after agriculture. The construction industry makes a remarkable contribution to the Indian economy and provides employment to a large number of people of India. Fire is a chemical reaction of a combustible substance with oxygen, involving heat and is usually accompanied by a visual flame or incandescence. Ensuring fire safety has always been a challenge to the stakeholders, i.e. building owners, construction companies, contractors and sub-contractors, and government employees due to the multiplicity of the factors involved and their complexity. There are various legal standards and requirements for ensuring fire safety on construction sites. The buildings are normally provided with firewalls during construction and these firewalls separate two structures or divide a structure into smaller portions to prevent the spread of fire. The lightweight construction and trusses are designed to support only their own weight. During a fire, if one fails, a domino effect happens and all fail rapidly within 5 to 10 minutes. Prolonged exposure to fire may result in structural collapse and injury or death of the occupants of the building under construction. Fire safety on construction sites is still in its primitive stages in India. There is a great necessity to improve fire safety on construction sites to protect construction workers and other occupants of the buildings. This study aims to design and implement fire safety systems for construction sites, thereby enhancing the standards to meet the system requirements at par with global standards.

Construction waste generation has been perceived as a crucial issue that has critical consequences on the project effectiveness and ecological effect of the construction industry. The key objective of the current research is to identify the root causes of material construction waste generation in Malaysia. A well-structured questionnaire was designed based on the 52 identified root causes of material waste generation. The developed questionnaire was distributed to 35 highly experienced in Malaysian construction industry experts. The collected data was analyzed by the use of mean score analysis. The top identified root causes are poor supervision during the construction stage, lack of efficient site management, last minute changes, cutting uneconomical sizes of materials, and constant design changes during the construction period. The initial findings will aid construction practitioners to focus on these root causes in order to reduce the material construction waste generation at construction sites.
