Linking environmental impact assessment and green procurement in the construction sector : opportunities and perspectives

Uttam, Kedar January 2011 (has links)
The construction sector has been greatly responsible for environmental pollution and problems related to sustainability. Hence, there is a crucial need to improve the sector’s environmental performance. In terms of assessing the environmental impacts of the construction sector at project and strategic level, policy instruments such as project-based environmental impact assessment (EIA) and strategic environmental assessment (SEA) play an important role. Another policy instrument, namely, green procurement has started to gain attention in the construction sector. Green procurement is a process that involves the incorporation of environmental requirements during the procurement of services and products. However, discussions on green procurement are rarely seen during the impact assessment (EIA and SEA) phase. Moreover, the construction process is usually multi-tiered, involving several stakeholders with varied objectives, which often leads to challenges concerning the translation of information produced in the impact assessment phase into action (during the construction phase). Therefore, this thesis aimed at analysing the way through which EIA as well as green procurement can improve the coordination between planning and construction phases. The thesis is based on literature review and interviews. This study envisaged an inter-connected process for EIA and green procurement, and reviewed the state of the art to motivate the postulation of such an inter-connected process. In addition, this study also reviewed recent development within procurement contracts, and focused on partnering in the construction industry. The results indicated that it would be appropriate to introduce green procurement during the pre-decision phase of an EIA. Further, the thesis chose renewable energy as a parameter for green procurement, and explored the perspectives of various categories of stakeholders in the Swedish construction on the inter-link between impact assessment and green procurement. The perspectives of the interviewed stakeholders indicate that the inter-link is required. However, the interview results show that there is a tendency in the Swedish construction sector to adopt various commercially available environmental assessment and certification tools. Furthermore, the thesis has mapped directions for future research. Future study should focus on the establishment of mechanisms for inter-connecting impact assessment and green procurement. It should investigate how the inter-link could be facilitated by certification tools being adopted. The future research should also examine how the inter-link can be developed together with concerned stakeholders through partnering. / QC 20111207 / Improving the environmental performance of the construction sector through linking environmental impact assessment and green procurement

Byggbranschens utveckling - ur ett hållbarhetsperspektiv / The development of the construction sector – from a sustainability perspective

Boquist, Tova, Andersson, Olle January 2024 (has links)
The construction sector must evolve to achieve environmental goals in Sweden. The development is slow and often entails significant risks for the actors in the sector, which requires incentives to drive progress forward. The study is based on 14 interviews and previous research, aiming to analyze and identify barriers and incentives for sustainable growth within the industry. The result shows that communication, economy and regulations are the main factors that affect the development in the construction sector. The factors were applied in a model, aimed to clarify and visualize the connections. The model shows that communication affects all factors, and in turn only impacted by requirements. Despite this, the connection between requirements and economy cannot be confirmed. Communication is considered to be the most crucial factor for the industry’s progress, as it according to the developed model, impacts all factors. Besides communication, clear regulations are needed to ensure sustainable development in the industry. The conclusions drawn indicates that there are numerous obstacles and a lack of incentives to develop the sector towards more sustainable construction. The most prominent barriers identified were, lack of knowledge, legal requirements and regulations, risk taking, insufficient customer demands and economics. As a result of these barriers, a number of incentives were identified as necessary: setting requirements, finances, collaboration and knowledge. The report is restricted to the Swedish construction sector, due to differences implementation of innovations compared to other countries. The analysis and conclusions are limited to what was brought up during the interviews.

Capital Accumulation, The State And The Production Of Built Environment: The Case Of Turkey

Balaban, Osman 01 February 2008 (has links) (PDF)
Under capitalist mode of production urban processes gain specific features and meanings. Fundamental is the relationship between processes of capital accumulation and the production of built environment. In this context, the capital switching theory claims that as profit levels are lowered, the probability that higher levels of capital tending to enter the property sector increases. In the first stage of a two-staged research, a macro-analysis on construction activities in Turkey limited to post-1980 period indicates that there no counter-cyclical relationship prevails between productive sectors of the economy and construction activities. It is observed that the state intervention and its supportive policies regarding the production of built environment are the dominant determinants in the Turkish case. Based on these findings, a second focus was on the relationships between the state and capital engaged in the production of urban built environment. Various forms of state intervention, mostly as examples of deregulation and liberalization of planning controls and urban development legislation are identified at this stage. The major findings lead to the conclusion that urban processes are open to the profit-oriented and speculative efforts of political actors as well as the economic actors. Hence the necessity of development of counter-strategies and policies as parts of planning and urban development system verified.

Contract Management Behavior Of Turkish Construction Companies In International Contracts

Yigit, Muhammet Alper 01 February 2009 (has links) (PDF)
Contract management starts with the contract negotiations and lasts until the end of the contract, and is the process that covers three fundamental functions required to compensate the goals of the project / Relationship Management, Project Delivery, and Administration of the contract. This thesis focused on investigating contract management behavior of Turkish construction companies in international projects. A survey was composed and interviewed with professionals for investigating the contract management behavior of contractors. The survey aimed to investigate / factors influencing contractors&rsquo / behaviors, key success factors for contract management, company contract management organizations, claim issues, and conflict and dispute resolution behavior of firms. 51 companies participated to the survey. The survey results revealed that Turkish contractors consider contract management to be significant for success at international markets. Contractors are aware of the need for a continuous contract management application although this rate cannot be achieved in practice. Considering awareness as a driving factor for improvement it can be estimated that in future Turkish contractors will be managing their contracts in more efficient, organized and systematic ways than today. Results revealed that / contract management behaviors are mostly affected by the risk and complexity of the project, regular contract process is the most impactful process on the success, and change order requests of the owners are the most frequent reasons of claims. According to respondents contract management can reduce number of conflicts and disputes.

Através da observação sobre as características da produção habitacional em cada cidade, o tipo de empresa atuante e os impactos no espaço urbano, conclui-se que o programa se comporta diferentemente entre as duas regiões. Enquanto em São Paulo a produção para os segmentos mais altos de renda esteve associada a uma estratégia de incorporação do capital internacional no portfólio das maiores empresas, em Recife a produção esteve direcionada à valorização das propriedades rurais recém-incorporadas à malha urbana. Estes resultados refletem os diferentes interesses do capital em cada região do país e demonstram que, apesar de defenderem grupos diferentes, seus interesses estes estarão sempre sobrepostos ao interesse social proposto pelo programa e como consequência as habitações para a população mais pobre são deixadas em segundo plano. Essa conclusão está em consonância com o que se pode esperar de um programa com referencial neoclássico baseado na liberalização do mercado. / Inspired by a marxist theoretical reference, this work aims to analyze the Brazilian housing program “Minha Casa, Minha Vida” in its historical context, stressing it differences in two regions of Brasil, which one with its own socioeconomics particularities: São Paulo and Recife. Supported by the observation of the housing production within the program, the type of company involved and its impacts on the urban transformation in each city, we intend to reveal how the program works on those realities. While in São Paulo the production seems to predominate on the highest extracts of income, strategy associated with the objective of incorporation of those companies on the worldwide capital markets, in Recife the production, seems to be oriented to increase the value of the land recent incorporated on the urban limit. Those results show the differences of capital interest in each region of the country and despite its dissemblance, they both seems to overlap the need for popular housing to valorize the gains of capital. This conclusion corroborates with similar results obtained by the mainstream paradigm, on which the base of the program relies on.
