Impact of construction projects on sustainable landscape: a systematic review

Human activities related to land use, such as the transformation of natural landscapes into urban areas and agricultural fields, as well as changes in land management practices, have caused substantial modifications to the Earth's surface. These alterations have had significant consequences for climate, soil, hydrology, biodiversity, and ecosystem processes. The research presented in this study provides a comprehensive summary of previous investigations in the field of landscape research. The main aim of this paper is to make a comprehensive review about the effect of the construction projects on the sustainable landscape , the results found that the projects effect adversely on the landscape and the free re should be increased.

Research on CLUFS and Its Application in Rapid Prediction of the Impact of Regulating Services Value in Construction Projects

With the development of human society and the acceleration of urbanization, the impact of construction projects on the ecological environment is increasingly attracting attention. Conducting an ecological environmental impact assessment of construction projects is crucial to protect the ecological environment and achieve sustainable development. To estimate how construction projects would affect the value of ecosystem services, this paper develops the China Land Use Feature Data Sets (CLUFS) and uses the Beijing “One Line Four Mines” project as an example. Research found that the project’s conservation and restoration zone and the landscape construction zone will significantly enhance the ecosystem regulation services value. The conservation and restoration zone will increase by 30% from the current 1.413 billion yuan per year to 1.836 billion yuan per year, and the landscape construction zone will increase by 69% from the current 400 million yuan per year to 676 million yuan per year. The tourism development zone, dominated by urban construction, will result in a decrease in ecosystem regulation services, from 19.26 million yuan per year to 17.60 million yuan per year by 9%. Overall, the “One Line Four Mines” project achieved a balance of ecological value and surplus. The method proposed in this paper for predicting the impact of ecosystem regulation services value on construction projects can be used to quickly evaluate the effects of different planning schemes on the ecosystem services value of land parcels to help urban planning decision-makers control the condition of land use. It can provide new indicators for the ecological environment department to incorporate ecological benefits into the evaluation system of planning schemes and new methods for evaluating the ecological protection effectiveness of projects.

Amphibian habitat network planning based on the graph theory: A case study of Pelophylax nigromaculata.

Both biodiversity conservation and the construction of biological habitat networks are key components of territorial spatial planning in China. Improving the landscape functional connectivity of biological habitat networks plays a vital role in biodiversity conservation. Although biological habitat network planning is a hot topic in literature, there is still lack of operable technological and methodological support in practical planning. According to the graph theory, the following three different aspects of biodiversity conservation and ecological network construction should be addressed in territorial spatial planning. First, the importance of biological habitat patches should be evaluated to determine the priority of patch protection. Second, the best locations for adding new elements should be identified to increase landscape functional connectivity of biological habitat network. Third, the impacts of construction projects should be judged and the potential impact of new construction projects according to the reduction of landscape function connectivity should be evaluated. We applied such framework to the network planning of amphibian (Pelophylax nigromaculata) habitat in Xiong'an New Area. The results showed that graph theory approach effectively met the requirements of those three aspects. The identification of the five optimal locations of new habitats of P. nigromaculata improved the overall landscape functional connectivity of habitat network by 19%. Four optimal locations of cross passage were identified to reduce the impacts of G45 expressway by assessing its impacts on functional connectivity of the amphibian habitat network.

Assessing Architecture-and-Landscape Integration as a Basis for Evaluating the Impact of Construction Projects on the Cultural Landscape of Tourist Seaside Resorts

The coastline of Western Pomerania has natural and cultural assets that have promoted the development of tourism, but also require additional measures to ensure the traditional features and characteristics are protected. This is to ensure that new developments conform to a more uniform set of spatial structures which are in line with the original culture. Today, seaside resorts are characterized by a rapid increase in development with a clear trend towards non-physiognomic architectural forms which continually expand and encroach on land closer to the coastline. This results in a blurring of the original concepts that characterized the founding seaside resort. This study evaluates 11 development projects (including a range of hotels, luxury residential buildings and hotel suites) built in 2009–2020 in the coastal area of Western Pomerania. An assessment of architecture-and-landscape integration for each development project was made, using four groups of evaluation criteria: aesthetic, socio-cultural, functional and locational factors. The study methodology included a historical and interpretative study (iconology, iconography, historiography) and an examination of architecture-and-landscape integration using a pre-prepared evaluation form. Each criterion was first assessed using both field surveys and desk research (including the analysis of construction plans and developer materials), and then compared with the original, traditional qualities of the town. This study demonstrates that it is possible to clearly identify the potential negative impact of tourism development on the cultural landscape of seaside resorts, and provides recommendations for future shaping, management and conservation of the landscape.

Evaluate the UK Construction Project Impact and Response Strategies during the Epidemic through Malaysia and China

2020 is a special year, this year the world’s economy has become extremely unstable because of the arrival of COVID-19. Idiosyncratic shocks have hit the global economy. The stock market has suspended, companies have closed, unemployment has soared, every industry has faced the biggest crisis since the Second World War. The British construction industry is certainly no exception. This time it will be the victim of this epidemic and the financial crisis. Compared with the European and American countries, the impact of the epidemic in Asia (Malaysia and China) is relatively light. The development of the epidemic situation in these countries has been controlled relatively effectively and strictly controlled. They are inextricably linked. However, the impact of construction projects in any area under the epidemic, the countermeasures adopted by the government, the epidemic prevention measures adopted by the company and the risk prevention strategy are very different. Therefore, under different circumstances, whether it is from the construction industry managers themselves or government policymakers, it is essential to apply correct and valid management measures to face the projects under construction under the epidemic actively. Simultaneously, collect statistics from questionnaire surveys of three countries in the region, then get an experimental result. Besides, different countries have different policies and forms of epidemic development. So, this research will summarize the corresponding policies and coping strategies of the project. It based on statistics of Malaysia and Chinese construction Projects, surveys for five projects to make comparisons than do statistics to the survey result.

Lack of maintenance of motorway fences works against their intended purpose with potential negative impacts on protected species

Linear infrastructure intrusions into natural ecosystems, such as motorways and high-speed railways, causes direct loss of habitat but also impacts fauna through collisions. Wildlife road mortality is well documented and extensive conservation legislation exists in many countries to minimise the negative impact of these infrastructures. However, although these measures are implemented because of legislation, these structures are often not adequately maintained. Here we present data on the functionality of perimeter fences along two motorways in Malaga province (southern Spain) erected to prevent collisions with the common chameleon (Chamaeleo chamaeleon). We sampled the fences along the 14 km of the two motorways included in the 17 1 × 1 km squares of the study area. Our results show that the reptile fence is permeable throughout at those points where the metal sheeting was absent and where the vegetation had overgrown around the fence, hence allowing chameleons to cross. Given our results, we conclude that this situation is likely to be similar in other regions of Spain and in other countries. This is because construction/concessionary companies do not consider the environmental impact of construction projects in the medium and long term, and environmental authorities do not ensure that companies comply with the legislation.

Energy consumption of bridge construction: conventional vs precast girders

One of the ways to reduce the negative impact of construction projects on the environment is reducing energy consumption. This study aims to calculate the energy consumption of a bridge construction project on the conventional beam girder and the precast girder. Data collection was carried out on the Salatiga-Surakarta toll road bridge project package 4.1 through field observations and interviews with project stakeholders. The results showed that the estimate of conventional girder energy consumption during the raw material transporting stage is 2.857 MJ/km.m3 (4.87%), during the production is 19.989 MJ/km.m3 (34.11%), during the transporting to the location is 3.56 MJ/km.m3(6.07%), and lastly, during the construction stage is 32.201 MJ/km.m3 (54.94%). While the estimate of energy consumption of precast girder at the raw material transporting stage is 2,897 MJ/km.m3 (5.27%), during the production is 49.627 MJ/km.m3 (90.29%), the transporting to the location is 0.957 MJ/km.m3 (1.74%), and during the construction stage is 1.485 MJ/km.m3 (2.70%). The total energy consumption of conventional girders is 58.606 MJ/km.m3 (51.60%), while for precast girder is 54.965 MJ/km.m3 (48.40%). The conventional girder energy consumption is 3.20% greater than the precast girder, thus, in this case, the precast girder is the best alternative to reduce the energy consumption during bridge construction activities. This study provides an understanding of environmental impacts based on the amount of energy consumption of conventional and precast girders, which is useful in the selection of girder beam types that are more environmentally friendly.

Can Traffic Impact Analysis Help with China's Green Transportation?

To manage the traffic impact of construction projects, the Chinese government requires the project approval procedure that should include a Traffic Impact Analysis (TIA). Using a case study, we illustrate how the TIA tool being applied in the procedure, and evaluate its effectiveness in terms of public transportation’s land area, trip generation ratio, subsidies and hub location. We employed Czaika and Hein’s (2013) evaluation framework of policy effectiveness, and found the TIA tool produced positive results, especially in allocating land areas and building terminals for public transportation. We also found that the key to increasing effectiveness lies in the processes of translating national guidelines to local ones and producing the TIA proposal.

Value Theory of Lean Construction in China

The purpose of this paper is to investigate the common perspective of value for lean construction (LC) researchers and practitioners. Thus, this paper aims to generate a future discussion in the construction sector about the huge impact of construction projects over the entire society and, consequently, to underline the need of an expansion of current value perspectives moving from a local context (project level) to a global context (society). LC value perspectives lack in a common idea to be applied in the construction industry as a whole. Customer-focused construction practices, where satisfaction of customer requirements predominates over societal welfare. Practical implications – Construction industry should reformulate current practices and governments, as representative of the society, should promote construction regulation policies based on delivery of value including environmental and social issues.

Comprehensive Fuzzy Assessment on the Life-Cycle Environment Impact of Bridges

A life cycle assessment (LCA) framework using fuzzy mathematics was developed to evaluate the environmental impact of bridges. The bridge life was divided into 5 stages: bridge design, raw materials processing, construction, operation, and demolition. An evaluation index system was established by analyzing the environmental impact of a bridge. Bridge life-cycle environmental impact was categorized into 5 grades: great negative influence, little negative influence, no influence, little positive influence, and great positive influence. Based on the improved AHP method, a fuzzy method was introduced to evaluate comprehensive environmental impact of bridges. The Highway Yangtze River Bridge in TaiZhou City in JiangSu Province was analyzed as a representative case study. Results show that major environmental impact appears during raw materials processing and construction. The method can be used to assess the life-cycle environmental impact of construction projects and help the stakeholders make decisions.

Sustainable Development &amp; Construction Industry

One of the key policies of many governments the world over is sustainable development in construction. This is due to the fact that the construction industry alone has a tremendous impact in the way the natural environment is affected by human activities whenever construction takes place, the surrounding environment will get affected. Due to this, the emphasis has been placed on sustainable development and both the need and responsibility of citizens and companies alike to do their utmost to reduce or minimize the impact human activities can have on the surrounding environment . The idea of sustainable development grew from numerous environmental movements in earlier decades and was defined in 1987 by the world Commission on Environment movements in earlier decades and was defined in 1987 by the World Commission on Environment and Development (BrundtlandCommsission1987) as: This contributed to the understanding that sustainable development encompasses a number of areas and highlights sustainability as the idea of environmental, economic and social progress and equity, all within the limits of the world’s natural resources . In short sustainability means meeting the needs of today without compromising the ability of future generations to meet their needs. Objective of the research are: 1. To critically analyze impact of construction projects 2. To study the doctrine of sustainable development in the light of judicial perspective 3. To frame construction environmental policy

A Composite Bridge is Favoured by Quantifying Ecological Impact

Carrying traffic loads is not the only objective of bridge designers nowadays. Other demands include constructing a bridge in a sustainable way, which reduces pollution and other harm to the environment. In The Netherlands, the government responds to such demands by promoting technologies and materials that decrease the environmental impact of construction projects. An assessment of that impact is, however, quite complex for bridge projects. The existing analytical methods, such as life-cycle analysis (LCA), require an extensive data input. Moreover, their results are more reliable for relatively simple products of short life cycles, for example, door or window frames, than for complex construction projects. In construction projects, the life cycles cannot be determined with the same precision and the materials are usually chosen in the very early stage of design. As a result, the data required by the LCA are often incomplete or even disputable. Therefore, there is a demand for ecological analysis methods that enable quick scanning of several material options, require less-extensive data input and are hardly, or not, vulnerable to arbitrariness.

Design of sustainable buildings through Value Engineering

Sustainability of current and new developments has become a major issue facing policymakers, developers, city and urban planners, and designers worldwide. Each new construction project entails, among others, the use of natural materials and the consumption of energy, which have a tremendous impact on the built environment over decades, and their environmental consequences only become fully apparent to future generations. The impact of construction projects on environment is especially significant in developing countries. The deterioration of building systems – including building materials – attributes to the economic, cultural and environmental problem, which is related to and affects the sustainable development of any society. In addition, developing countries have suffered for a long time from overlooking or underestimating the basic requirements that must be considered for designing sustainable developments. This article attempts to propose a practical solution for designing sustainable developments by focusing on the building as the primary unit. First, this article presents the requirements for designing a sustainable building, as well as the current process for selecting sustainable building systems and materials. Second, this article describes the Value Engineering program, including the different phases of the job plan. Finally, this article proposes a method for improving building sustainability. The proposed method utilizes the job plan of the Value Engineering program – together with a database that contains up-to-date information on construction systems and materials – as a gear for studying and analyzing the sustainability requirements.

The Local Economic Impact of Construction Projects in a Small and Relatively Self-contained Economy

Whilst the local multiplier impacts of the annual operation of universities has been the subject of intensive research, the economic impacts of capital construction projects have been almost completely ignored. This paper presents the results of detailed analysis of capital projects at Lancaster University in 1993- The reasons for the radically different annual operation and construction multipliers estimated in the Lancaster study are examined. Despite the smaller size of construction multipliers it is argued that it is a serious mistake to estimate local construction multipliers by making simplifying assumptions on the size of the key parameters in the multiplier equations.
