Metallurgical Design Project concerns interactions, integrations and significant relationships in socio-economic systems [1] . By doing reference to the metallurgical business, it contributes more through supplying the capital goods and materials needed for construction [2] . Sustainable development requires the basic infrastructure implementation which most materials are at the metals origin. The increase in demand for goods derived from metals at market directly causes the existence of the additional demand [3] . Faced with an imbalance between supply and demand, the firm’s behavior is often to revise the prices upwards. The increase in production volume by competitors, enable to balance supply and demand in the market [2] [3] . Additional production has enabled to satisfy the additional demand; thus, the market price is the equilibrium price. Indeed, all stakeholders in the market draw from profits. This is a schema which the result leads of win-win outcome. The company withdrawn more profit when there is an imbalance between supply and demand; the price subsequently soared [4] . On the consumer side, they receive gains occasioned by the difference between the price at which the consumer is willing to buy and the equilibrium price [4] [5] . Other studies address the importance of Corporate Social Responsibility (CSR) especially in the process of promoting sustainable development [6] . Indeed, CSR is rather focused on ethical behavior related to three components: environment, society and economy [7] . When the heavy or processing companies are going to proceed in production, they often set up a CSR policy before all the operations, in order to deal with negative externalities caused by the production. CSR is known as a means enabling to repair the damage from the exploitation and/or production towards the environment and increase in value the social dimension that is often overlooked [6] [7] .

Promoting metallurgical project encourages sustainable construction activities. Products quality improvement is at the origin of design research in the production units [8] . This means that the products quality determination destined for selling is the result of the design study undertaken. Upstream research considers products design and this design that has been designed beforehand will be defined by the quality of materials or capital goods after having followed the production process [9] . A product differs from another by its quality. This one is considered as an indicator choice for the client. Before embarking on the purchase, the customer first examines the product quality which he intends to buy. This amounts to saying that the buyers’ choice focus on the quality preference and it will then be lead to take the decision to purchase [8] . Sales improvement of the company is resulting from increasing units’ number of products sold at market. Given that the cut-throat competition, it is difficult to increase the volume of products sold from one year to another. Indeed, in order to reach this challenges, the company must remain competitive in front its competitors [10] . Products quality improvement is an effective tool to ensure the pace of competition in the international market [8] [10] . Turnover improvement implies that the company has increased profits. This situation gives rise to a positive externality in the context of the sustainable development process. Promoting sustainable construction practice is the result of increase in new values created after increasing profit. The total of added value determines the Gross Domestic Product (GDP) which ends in economic performance [11] . The latter provides the necessary means within the framework to pursue a balance in the social and environmental fields. Various methods likely to reduce the pollution generated by the factory production have been made; the prevention of waste production constitutes a way that involves less damage to the environment [12] .

Always in order to reduce the damage risk caused by the economic growth to the environment level, the current trend of large company producing capital goods and equipment materials converges towards recycling waste in the production of materials and equipment [11] [12] . Waste reusing processed into raw materials and then used again in the component of the production factors combination is very beneficial not only to society but also very profitable to the company [13] . Metallurgical project design is a vector for innovation in all sectors including sustainable construction. One cannot imagine the innovation without to pass by the design study. Technical progress and technological development enable to promote an upward evolution within the framework of the products design [14] . The companies offer materials and equipment goods with high technology responding innovation policy required by the sustainable development without compromising the environment. However, it is clear that the concept of sustainability is oriented generally in the construction sector; the sustainability research can cause a conflict between environmental benefits in long term and operational economic objectives in short-term [15] . The sustainable development philosophy consists generally to meet the basic needs of the population and to respond the aspirations of the well-being of everyone without compromising nevertheless to expand the possibility to guarantee a better life for future generations [16] . Promote future generations requires the

control of the tripartite balance, balance of environmental protection, economic development and social development. The three components that make up sustainable development: environmental protection, economic development and social development necessitate the money to engage investment projects in these three respective fields [15] [16] . In this sense, some studies have suggested that the adoption of sustainability principles in the process of implementation of construction projects can contribute to profit making [17] . It is particularly very important to adopt the principle of conducting a project design study. The purpose of this study is to design directly consumable products that exactly meet to the trend of customers at market level [18] . On the other side, it also enables to assess the likely estimate on the quality of metallurgical products which the markets have needed but also especially to calculate approximately the damage cost generated during production, properly speaking. Indeed, strategies such as CSR are proposed to implement sustainable practices [19] . Therefore, design studies projects are often conducted in advance for having a better understanding on the one part and then to facilitate reaching the expected objectives: acquiring durability in the process of sustainable development including the implementation of construction project is a major part [20] . Project design implementation is often preceded by a feasibility study. The project success will be conditioned by a perfect conclusion of design and construction. However, it is difficult to pretend to land at a good realization when the feasibility study which was undertaken is not effective. Traditionally, the project feasibility study is focused on financial issues. It is a question of calculating the output investment rate, of estimating the imbalance between supply and demand quantity available in order to deduct the additional demand quantity, and finally of assessing the competition weight in the traditional market and the integration cost in the new markets [19] . It is clear that the feasibility study is a pet hate for the designing success indeed of the developing project [20] . It indicates the purely technical aspects which understanding is complicated by a simple lecture. Nevertheless, it is the most important stage; having committed mistakes at this stage might be permanently handicapping the project’s performance even fatally. A feasibility study upstream considered adequate and effective is just a set of financial projections that may have repercussions downstream on the market-driven strategic plan and a roadmap for all subsequent decisions.

Given that sustainable development is the result of the improvement of sustainable economic growth, indeed, the promotion of sustainability has become increasingly important in various sectors of activity. One is particularly in levels of production units operating within companies. As most production at factories give off toxic waste that will harm the atmosphere, rivers, sea etc. finally, human life is threatened [21] . Ultimately, the aim of promoting the social and economic issues has become the vector potential threatening environmental issues in the current practice of the project construction [22] . This fact leads us directly to introduce the assessment of the environmental impact in the study design project whose objective is to recommend the repair of damage caused during production [23] . Undoubtedly, economic agents especially those working in heavy industries and processing industries such as the case of CCTEC Co. Ltd. are polluters, and it has widely reported and heavily criticized by environmentalists [21] [24] . The tasks division is clear and sharp. The government sets the environmental protection policy and ensures the implementation of the related activities with Non-Governmental Organizations concerned. Companies are a part of the mechanism propulsion economic development. The government encourages them to increase investment so that there is an annual increase of newly created wealth [25] . Given that the primary objective of the company is to maximize profit, thus they have the tradition of focusing on controlling fixed costs such as salaries, production costs and the production cycle duration along with the quality of products [26] . Despite certain studies, propose solutions to minimize distortion of the environment, environmental and social performances remain still precarious in China [16] [21] [23] . The increase in the allocation for CSR is difficult to imagine, therefore it is still limited. This limitation is the origin of industry culture centered on profit where cost, quality and schedule were key factors to ensure super profit [27] . Actually, China is the country of destination of American and European industrialists to set up annex industries. The industry transfer is doing so in order to making profit owing to cheapest labor in the country [28] . It also reduces the risk of environmental degradation in the United States and Europe in order to escape the climatic problem generated by climate change. Indeed, the industry activities in China have resulted in economic boom; the economy experienced a marked improvement after the increase in job creation [25] . This one contributes in improving endogenous income redistribution; each household could increase its consumption level through his salary [29] . A significant improvement was also noted at the public treasury due to an increase in tax revenue and especially the increase in foreign currencies reserves at the central bank due to the overwhelming influence of international trade [30] . This ensures the stability of the Chinese money Yuan or appreciation of its value [31] [32] . The preponderance of export is the origin the development of Foreign Domestic Investment (FDI) [28] . However, secondary effects were registered during industrial activities such as environmental pollution, resource waste, security issues and the public interest [21] [23] [24] . These problems mentioned have major incidence in the context of implementing the principles of sustainable development in China [16] [21] . In fact, there is a contrast which manifests itself between better environmental protection and current practice of the investment project. Therefore, this paper aims to examine the current practice of conducting research on the design of the project by taking the case of CCTEC Co. Ltd.

To provide heated discussions and in-depth understanding of this research, a case study approach has been chosen to illustrate the study. From September to December 2013 period of my internship in CCTEC Co. Ltd, I had an opportunity to conduct an inventory of sales register during four commercial years 2008 to 2011. Indeed, 158 machinery units (such as Billet CCM, Bloom & Round CCM and Slab CCM) were purchased by Iron & Steel and Equipment & Engineering companies, which selling classification is as follows: 52 units in residential projects (PI), 50 units in the public sector projects (PII), 37 units in the industrial projects (PIII) and 19 units in the commercial projects (PIV). Both type of companies whose economic function is to provide construction materials and equipment goods, stimulate a snowball effect on various projects enumerated above. The interview with Financial Manager enables to obtain first-hand information on the practice of conducting study regarding the impact on socio-economic and environmental issues. The examination of these cases in Hubei and Guangdong provinces leads to understanding on what and how CCTEC Co. Ltd. was attributed through Iron & Steel and Equipment & Engineering companies within the current framework of promoting sustainable development. Therefore, the analysis cannot be given whether these attributes are correct or sufficient for the sustainable development principle implementation. Challenges can reveal for the practical implementing of sustainable construction in China. The protection of local processing companies should be strengthened in order to accelerate the mutation process towards the sustainable development principle while highlighting areas that have not been given attention. Measures should be taken to improve the weak points.

The production of capital goods by metallurgical company contributes largely to the achievement of various projects. The contribution degree can be measured by examining the factors or attributes provided by these capital goods supplied in relation to the expected result. These attributes can be viewed in three main areas: namely economic performance attributes, social performance attributes and environmental performance attributes. This paper was shown the attributes importance in each domain with the reference to the Chinese context.

Promoting sustainable development requires stimulate economic growth which it has an induced effect on new expansion of social and environmental issues. Indeed, first of all, the study of socio-economic and environmental impact is irrefutable about industrial or construction projects. This study will discern the economics’ advantages on one hand, and environmental disadvantages induced on the other hand [33] . Research focused on the project implementation such as CCTEC Co. Ltd. should emphasize more on methods that enables for improving the quality of economic performance, social and environmental for the future of the industry practice. This comes down to say that it is time to replace the traditional approach by a new approach which embraces the principles of sustainable development.

The mutation process towards sustainable development is a long and exacting task; indeed, the government cannot assume to itself the sustainable development principle implementation [34] . Subsequently, everyone’s contribution including population and the private sector is undeniable.

This paper decrypted economic interest provided by the existence of processing industries. The economic development resurgence is reflected partially in the social field. Indeed, the supply of capital goods and construction materials promotes the basic infrastructure development including the public sector, residential projects, industrial and commercial. However, the implementation of these four projects will not let the environment state remains intact. Analysis on production process practice and especially the followed of the use of products has enabled to set four types of attributes. Seventeen economical, nine social and seven environmental performance attributes were explored from 158 sold machinery. The result attained in the projects has made considerable impulsion on the economic aspect. The economic situation improvement has not significantly impact on everyone life, in contrast, the natural environment state has deteriorated further, which indicates that the distribution of wealth newly created is not fair. Individual factors derive considerable profits at the expense of the population victim of environmental pollution. The traditional approach is lapsed; indeed, it is no longer question to take into account the traditional approach in studies of project design. The use of the new approach is strongly recommended from design in passing by operation until the project is to its terms. In this sense, work together between all stakeholders is indispensable including government, clients, NGOs and contractors and suppliers [39] [40] .
