Gestão e gerenciamento de resíduos da construção civil em obras de grande porte: estudos de caso / Civil construction waste management in large construction works: case studies

Flávia Gadelha Martins 15 June 2012 (has links)
O crescimento da economia brasileira proporcionou uma intensificação na quantidade de obras de infraestrutura iniciadas no país nos últimos anos. A adoção e ampliação de estratégias utilizadas pelo governo para combater os efeitos da crise internacional sobre a economia e as obras necessárias ao país, em razão de eventos internacionais que acontecerão, como a Copa do Mundo de Futebol em 2014, e de programas como o Programa de Aceleração do Crescimento (PAC), foram uma resposta às atuais necessidades do Brasil. Com essas inúmeras obras, houve um crescimento na geração dos resíduos da construção civil (RCC), o que fez com que autoridades, pesquisadores e a sociedade voltassem seus esforços para enfrentar as dificuldades de manejo e disposição final adequada desses resíduos. A ausência de políticas públicas que promovessem a fiscalização do gerenciamento desses resíduos, em relação aos geradores, provocava diversos impactos como, por exemplo, o surgimento de vários depósitos clandestinos nas áreas mais afastadas do perímetro urbano e gastos por parte da administração pública com modelos de gestão corretiva. Contudo, com a elaboração da Resolução CONAMA nº 307/2002 e da Política Nacional de Resíduos Sólidos, Decreto nº 7.404/2010 que regulamenta a Lei nº 12.305, ficou instituído que os geradores devem ser responsáveis pelos resíduos das atividades voltadas à construção civil, contemplando, assim, a minimização dos impactos causados ao meio ambiente e à saúde humana. Dessa forma, esse quadro de descaso com a situação dos resíduos começou a mudar. Com a intenção de contribuir com essa área de conhecimento, esta pesquisa teve como finalidade estudar a situação do sistema de gerenciamento de RCC de obras de grande porte, após a regulamentação da Resolução CONAMA nº 307/2002 e do Decreto nº 7.404/2010, que regulamenta a Lei nº 12.305, referente à Política Nacional de Resíduos Sólidos. Para tanto, foi realizado um estudo da situação da gestão e do gerenciamento dos RCC na demolição e construção da Arena Fonte Nova, em Salvador - BA, e na construção da Arena Pernambuco, em São Lourenço da Mata - PE, realizadas para a Copa do Mundo de Futebol de 2014, por meio de três etapas de estudo: análise das variáveis e indicadores locais; caracterização qualitativa dos resíduos; e, por fim, comparação do gerenciamento da obra com o preconizado em ambas as leis. Esta pesquisa utilizou metodologia de classificação qualitativa do RCC, por meio de observações e entrevistas de campo, com o objetivo de identificar e analisar sua gestão e seu gerenciamento nessas obras, e teve como principal importância ajudar as empresas construtoras de obras de grande porte a fazerem uma autoavaliação de sua gestão e gerenciamento dos resíduos sólidos. Portanto, concluiu-se que as obras pesquisadas atendem às exigências das leis e que, para que haja um efetivo sistema de gestão e gerenciamento dos resíduos da construção civil, deve-se influenciar a mudança cultural das pessoas, visando a efetiva compreensão e concordância das necessidades ambientais. / The Brazilian economy has provided an enhancement in the amount of infrastructure works initiated in the country in recent years. The adoption and expansion of strategies used by the government to combat the effects of global crisis on the economy and the works necessary for the country due to international events that will happen as the FIFA World Cup in 2014 and programs such as PAC (Program Growth Acceleration), were a response to the current needs of Brazil. With these numerous works, there was an increase in the generation of civil construction waste (CCW), which meant that the authorities, researchers and society return their efforts to face the difficulties of handling and final disposal of such waste. The absence of public policies that promote the monitoring of waste management in relation to generators, caused many impacts, for example, the emergence of several underground deposits in the areas furthest from the urban perimeter and spending by the public administration models corrective management. However, the drafting of the CONAMA Resolution 307/2002 and the National Policy on Solid Waste Decree 7.404/2010 which regulates Law 12,305, it was established that the generators should be responsible for waste from activities related to construction, encompassing thus minimizing the impacts to the environment and human health. Thus, this picture of neglect with the waste situation began to change. Intending to contribute to this area of knowledge, the present study was aimed to study the situation of the CCW management system for large works, after the implementation of Resolution CONAMA 307/2002 and Decree regulating 7.404/2010 Law 12,305, on the National Policy on Solid Waste. To that end, a study of the CCW management situation was conducted in the demolition and construction of the Arena Fonte Nova in Salvador - Bahia, and in the construction of the Arena Pernambuco in São Lourenço da Mata - PE, performed for the FIFA World Cup 2014, through three stages of study: analysis of variables and local indicators, qualitative characterization of the waste and, finally, comparing the CCW management as recommended in both laws. This research used the qualitative methodology of the CCW, through field observations and interviews, in order to identify and analyze the management of these same works and its main importance to help manufacturers of major works to make a self- evaluation of its management and solid waste management. Therefore,it was concluded that the works researched met the requirements of laws and that to have an effective management system of civil construction waste, must influence cultural change in the people, in order to enhance comprehension and compliance of environmental needs.

An investigation of the document bias between the GCC 2004 and the GCC 2010

Klingenberg, Wolfram Georg 04 1900 (has links)
Thesis (MEng)--Stellenbosch University, 2014. / Construction projects have developed over several decades through the advancement of technology, increased scarcity of resources and the ever increasing pressure of time and cost constraints. Because of new technology and modern construction methods, construction projects have become increasingly complex. These complexities inherently bring new risks that must be dealt with accordingly. A contract is the primary method through which risks are allocated between the Employer and the Contractor. The conditions allocating the risks legally bind both parties to accept responsibility of those risks, therefore it is important to understand the aspects of law that has bearing on contracts. In this thesis the scope is restricted to construction contracts. Because of the role that a contract plays, especially in the construction industry context, it is important to know the requirements of a modern contract to ensure the successful completion of projects and the continued sustainability of Employer-Contractor relationships. In South Africa, the Construction Industry Development Board (CIDB) is a body that monitors developments in the construction industry. The CIDB has the authority to enforce legislation to ensure that contracts conform to a standard that protects the interests of both the Employer and the Contractor. One of the procurement documents endorsed by the CIDB is the General Conditions of Contract for Construction Works published by the South African Institution of Civil Engineering (SAICE). The first edition of the GCC was published in 2004 (GCC 2004) and a revised second edition was published in 2010 (GCC 2010). In this study the GCC 2010 and the GCC 2004 are compared first through a content analysis, to establish the effect the revisions on the bias of the document (or favouring a particular party) and then by means of a survey. The objectives are: a. To test whether revisions to the GCC from the 2004 edition to the 2010 edition resulted in a change in bias (assuming it exists) and compliance with the requirements of the modern contract; b. To determine the extent and effect of alterations to standard clauses of the GCC 2010 on the way in which the contract favours a particular party; c. Providing recommendations for future revisions that would potentially improve project success, relationship building and reduce the need for significant alterations to the standard clauses. Although a construction contract is undertaken between the Employer and the Contractor, the Consultant (who is not party to the contract) commonly drafts the contract on behalf of the Employer. The findings of the study show that the revision had a significant impact on improving the clarity of the roles of the Employer and the Contractor. A marginal improvement was found in the area of payment operating mechanisms. The perceived fairness of the document neither increased nor decreased. Clauses on claims and disputes and risk and related matters were the two areas that respondents identified as having the most bias that may be detrimental to the success of a construction project. Despite survey respondents finding the GCC 2010 procurement document to be fair, clauses are still altered by Employers (probably through Consultants) resulting in a biased contract favouring the Employer. Employers and Consultants should thus be educated more on bias and fairness in contracts and on the implications of shifting more risk to Contractors by altering clauses. Ultimately, the success of any construction project is dependent on the attitudes of the participants. Even the most fair procurement document is not a substitute for a relationship built on honesty and trust.

Kommunala särkrav : En studie om i vilken utsträckning kommuner bryter mot förbudet i PBL 8 kap. 4 a § / Municipal special demands : A study of in which extend municipalities goes against the prohibition in PBL 8 kap. 4 a §

Svensson, David, Torbäck, Nils January 2016 (has links)
Den första januari 2015 trädde en ny regel i kraft, PBL 8 kap. 4 a §. Regeln innebär att kommuner inte får ställa egna krav på ett byggnadsverks tekniska egenskaper, även kallat särkrav. Med egna krav anses sådana krav som är mer ambitiösa än vad regelverket tillåter. Krav på byggnadsverks tekniska egenskaper finns angivna i plan- och bygglagen (PBL), plan- och byggförordningen (PBF), Europeiska konstruktionsstandarder (EKS) och i Boverkets byggregler (BBR). En anledning till förbudet är att särkrav anses påverka byggkostnaderna, vilket i sin tur påverkar förutsättningarna för att tillgodose behovet av bostäder. I utredningar som utfördes åt regeringen hävdades att särkrav medför merkostnader på mellan 10 och 15 procent vid bostadsbyggandet. Regeringen ansåg även att samma krav ska gälla över hela landet för att underlätta den industriella produktionen av byggnadsverk. När lagförslaget lades fram bemöttes det negativt av många kommuner och myndigheter, vilket gör det intressant att undersöka om kommunerna väljer att följa den nya regeln. Syftet med studien är att undersöka i vilken utsträckning kommuner, i bygglovsprocessen och vid upprättade av exploateringsavtal, bryter mot särkravsförbudet i PBL 8 kap. 4 a §. Studien utgår från exploateringsavtal och bygglovsärenden vars handlingar är upprättade efter 2015-01-01 då särkravsförbudet trädde i kraft. I studien ingår bygglovshandlingar från åtta kommuner i Västra Götalands län och exploateringsavtal från 34 av Sveriges kommuner. I studien används en kombination av en kvalitativ och kvantitativ metod samt en juridisk metod. Särkrav som förekommer i studien är klassificerade som tydliga eller vaga särkrav. Bedömning av särkravens klassificering är författarnas egna och utgår från grundsatsen att byggherren är fri att välja metod så länge föreskrifterna i BBR uppfylls. Studiens resultat visar att 24 av de 42 kommunerna som ingår i studien ställer särkrav, vilket motsvarar 57 procent av de granskade kommunerna. Tolv kommuner ställer tydliga särkrav, fyra ställer vaga särkrav och åtta ställer både tydliga och vaga särkrav. Var fjärde kommun hänvisar även till olika program, strategier eller policys där särkrav förekommer. I exploateringsavtalen är särkrav vanligast inom områdena hygien, hälsa och miljö samt energihushållning. I byggloven är särkrav vanligast inom områdena brandskydd, hygien, hälsa och miljö samt säkerhet vid användning. Studiens slutsats är att kommuner fortfarande ställer särkrav i stor utsträckning trots förbudet i PBL 8 kap. 4 a §. / On January 1, 2015, a new law came into force, PBL 8 kap. 4 a §. The law implies that municipalities may not impose their own demands on construction works technical properties, also known as special demands. Own demands are considered as demands that are more ambitious than the law allow. Demands on construction works technical properties are specified in the Planning and Building Act (PBL), the Planning and Building Regulation (PBF), the European Construction Standard (EKS) and in Boverket's Building Regulations (BBR). One reason why the prohibition came into force is that special demands affect construction costs, which affect the conditions to meet the need of housing. The government's investigations revealed that specials demands resulted in additional costs of between 10 and 15 percent in the residential construction. The government wanted as well that the same requirements would apply across the whole country to facilitate the industrial production of construction works. When the new law was presented it faced negatively by many municipalities and public authorities, which makes it interesting to examine if the municipalities choose to follow the new law. The purpose of the study is to investigate in which extend the special demand prohibition in PBL 8 kap. 4 a § are broken by the municipalities in the building permit process and in the establishment of land development agreement. The study is based on land development agreements and building permits documents that are signed after 2015-01-01. Building permit documents from eight municipalities in Västra Götaland and land development agreements from 34 of Sweden's municipalities are included in the study. The study use a combination of qualitative and quantitative methods as well as a jurisprudence method. Special demands which been presented in the study have been classified into clearly or vaguely special demands. The special demands classification are the authors own assessment and are based on the principle that the developer is free to choose the method as long as the regulations in BBR is met. The study's result points out that 24 of 42 municipalities that is included in the study, use special demands, which is equivalent to 57 percent of the audited municipalities. Twelve municipalities have clearly special demands, four have vaguely special demands and eight have both clearly and vaguely special demands. Every fourth municipality also refers to various programs, strategies or policies with special demands. Special demands are most common within the area of hygiene, health and environment and energy in the land development agreements. In the building permits are special demands frequently used within the area of fire protection, hygiene, health and environment and safety in use. The conclusion of the study is that municipalities still use special demands widely despite the prohibition in PBL 8 kap. 4 a §.

論台灣地區已完工公共工程的保險機制 / A study on the insurance mechanism for the civil engineering completed works in Taiwan

陳俊豪, Chen, C.H. Unknown Date (has links)
公共工程是國家重要施政項目之ㄧ,所提供的服務品質關係著國家經濟發展甚鉅。台灣地處亞熱帶及環太平洋地震帶,颱風、洪水、地震發生頻繁,公共工程的服務品質受天然災害的威脅甚大。近年來天災頻仍,面對天然災害所帶來的經濟損失,有許多國家已經開始透過保險方式,處理已完工公共工程遭受天然災害威脅時的財務風險,以減輕國家財政負擔,進而更合理的分配國家資源。 本研究將透過台灣地區天然災害發生的情形及我國目前在公共工程遭遇天然災害而毀損時的因應方式探討天然災害損失對我國財政的負擔;並介紹國際上主要再保險公司:瑞士再保險公司、慕尼黑再保險公司有關完工土木工程保險的承保範圍、核保方式,與東亞日本、南亞印度兩個國家經營完工土木工程保險的現況。 本研究並整理歸納透過商業保險來進行已完工公共工程的天災風險規劃雖較現行單以國庫承擔損失方式經濟,但可能面臨政府機關態度消極及產險業者承保能量不足兩個關鍵議題。惟以澳洲昆士蘭水患為例,慮及不可知的天災風險,仍建議政府機關能率同商業保險業者共同建立完整的已完工公共工程風險管理機制,攜手降低天災風險發生時可能帶來的傷害。 關鍵字:公共工程、天然災害、完工土木工程保險。 / Public Construction Works are always considered as one of the important national economic developing strategy. In view of Taiwan is located in the region which is highly exposed to natural disasters such as typhoon, flood and earthquake, the quality of the after service related to the Civil Engineering Completed Works is greatly threatened by the natural disasters. In recent years, there were many natural disasters occurred, in order to minimize the economic loss brought by such disasters, many countries have begun to arrange insurance placement for the Civil Engineering Completed Works to share the financial risks. This study introduces the loss circumstances of the public engineering works brought by the natural disaster and the impact of the economic growth in Taiwan. The major international re-insurers: Swiss Re and Munich Re both provide the Civil Engineering Completed Risks (CECR) Insurance to against the loss or damage after the construction work has been completed. This study introduces the difference coverage and underwriting as compared in between Swiss Re Form and Munich Re Form. This study also illustrates the current status in respect of CECR in Japan and India markets. This research induces a more economic method by arranging the Catastrophe Risks Plan through the placement by commercial insurance for the Civil Engineering Completed Works rather than the existing regulations that all these disasters bond by the government. Moreover, it also facing two problems are that the government is too conservative and the negative attitude as well as the in-sufficient capacity of the local insurance industry. For example, the serious flooding occurred in Queensland- Australia, the government should take into consideration how to prevent from the incredible natural disaster risks. We do suggest the government should corporate with local insurance industry to establish an completed risks management for Civil Engineering Completed Works to minimize the loss that brought by the natural disasters which may occur. Key Words: Public Construction Works, Natural Disaster, Civil Engineering Completed Risks Insurance (CECR)

Gestão dos resíduos de construção civil (RCC) integrada com a resolução 307 do CONAMA : uma aplicação de caso no município de Taubaté

Romária Pinheiro da Silva 31 March 2010 (has links)
Na indústria da construção civil não havia, até então, preocupação quanto ao esgotamento dos recursos não renováveis utilizados ao longo de toda sua cadeia produtiva, e muito menos com os custos ou prejuízos causados pelo desperdício de materiais, ou destino dado aos rejeitos produzidos nessa atividade. Partindo dessa premissa, este trabalho teve por objetivo estudar a gestão dos resíduos de construção civil (RCC) existentes no município de Taubaté, utilizando a Resolução 307 do CONAMA, buscando diagnosticar e apresentar uma proposta de destino para esses resíduos. Nesse contexto, realizou pesquisa bibliográfica e exploratória para tratar os dados existentes, juntamente com o método de estudo de caso, fundamentado pelo relatório de atividades que as empresas transportadoras dos RCC apresentaram ao aterro público municipal da cidade de Taubaté no ano de 2007. Verificou-se que o município possui eficientes empresas transportadoras dos RCC, porém ainda não possui um local adequado para a destinação final dos resíduos, e muitos dos geradores desconhecem a legislação. Dessa forma, evidenciou-se a necessidade de adoção de um modelo de gerenciamento para os resíduos da construção civil, dada a sua significativa presença em áreas urbanas e as conseqüências na qualidade de vida da população. Essa nova gestão deve ser caracterizada por ações integradas e de caráter preventivo, procurando sempre reduzir o grande volume de resíduos gerados pela indústria da construção civil. Além disso, torna-se também necessário o estabelecimento de diretrizes que venham reduzir o volume e também uma gestão eficiente para a correta destinação dos resíduos, objetivando a redução ou até mesmo a mitigação dos impactos causados pelos resíduos da construção civil, descartados sem reciclagem, reutilização ou sem reintegração do produto novamente na cadeia produtiva. / Based on the premises that the civil construction works havent properly dealt with the depletion of nonrenewable resources used in its productive chain, or with the costs and losses caused by material loss and much less with the disposal of resulting wastes, the present work is aimed at studying the civil construction wastes management processes performed in the city of Taubate. It makes use of the Resolução 307* by CONAMA in order to diagnose them and suggest possible final handlings to those residues. A bibliographical and exploratory study was carried out to check the existing data, along with a case study method based on the report presented to Taubates city garbage dump by the companies transporting civil construction wastes on their activities in 2007. Although there are efficient transportation companies, there is also a lack of adequate sites for the disposal of construction wastes, and many residue generators are unaware of the legislation. Therefore, a new management model for civil construction wastes has to be adopted and deal with the large amount of waste present in urban areas and the consequent damage to the populations quality of life. This new process must be preventive and characterized by joint-actions aimed at reducing the amount of civil construction waste, together with the establishment of policies that guarantee the reduction of its volume and its correct destination, having in mind the reduction or even elimination of the impact caused by civil construction wastes that nowadays are discarded with no recycling, reutilization or reintegration of the product to the productive chain.
