In petrochemical industry, the execution of construction involves three main issues, namely, design planning, construction, and job safety. Three-dimensional (3D) models are increasingly applied to design and construction. However, the improper concept of 3D design has bred potential unsatisfactory behaviors and the lack of vigilance among workers. Besides, many employees are not fully aware of the safety in 3D design and construction planning. Therefore, our goal is to improve the safety and health of construction workers through design practices in the upstream of the construction phase, and verify the applicability of the combination of 3D models and safety knowledge. Specifically, a questionnaire survey was carried out among 124 employees in the construction-related fields of the petrochemical industry. The collected data were processed, and statically analyzed on SPSS. The results show that safety knowledge was acceptable in 3D model design from the perspective of project executors, and the integration of safety knowledge into the design helps to improve the safety environment of the construction site.

With the development of urban subway system, intersection is sometimes inevitable during the construction of underground tunnels. When a tunnel to be excavated is underneath an existing subway station, the support wall of the station that lies on the way of the tunnel is often required to be partially dismantled to facilitate the construction of the tunnel. To ensure safety of the existing station and the tunnel, both metro jet system (MJS) using cement paste and artificial ground freezing (AGF) techniques can be applied and sometimes combined to stabilize the area under the influence of tunnel construction. However, when two techniques are combined, the hydration heat from the cement paste will bring an increase in the active freezing time. By taking advantage of an existing project, a preliminary numerical simulation is performed to evaluate the influence of hydration heat on a 100-day ground freezing process with considering the effect of ambient temperature, thermal insulation, and the timing of the initiation of the freezing after MJS treatment. Simulation results show that the active freezing time can be reduced by 53 and 3 days with thermal insulation at the end sections in summer and winter, respectively. Hydration heat leads to an increase of the active freezing time from 14 to 15 days, and the effect of timing for the initiation of artificial ground freezing is insignificant on the active freezing time. Subsequently, consistent with the construction plan and site condition, using the ambient temperature from the previous year, a numerical simulation is also performed to simulate the soil temperature variation during the releasing of hydration heat and the freezing followed. The simulation results show that 52-day active freezing time is required for the formation of a frozen soil wall which met the requirement for further tunneling.

We discuss the attempt to establish the Hospital Proletario in the capital of the state of Paraiba in the 1930s. To this end, we problematized the coverage in the newspaper A Uniao on this episode. The involvement of different actors - workers, associations and physicians - reveals the emergence of a new way of thinking and implementing healthcare policies. According to the Vargas government's national construction plan, actions like this were intended to ensure healthy workers - ready for the market and useful for the country. Despite its failure, the hospital project provided evidence of the different concepts of worker health during the Vargas Era. We identified the concepts of "health interdependence," "social medicine," "regulated citizenship" and the "labor movement."

The article is devoted to a policy document that defines the main directions and principles of creating a social credit system in China. It is shown that the reform plan and the ongoing changes are quite consistent with the Chinese bureaucratic traditions of coercion and paternalism, and are associated with the use of a social regulator that forms the appropriate behavioral incentives, such as reputation. Ultimately, the new model of social governance is aimed at ensuring social and political stability in China and proactively addressing the development problems of Chinese society.

Under the background of rapid urbanization, all kinds of urban water problems have gradually come into being: local flooding frequently happens, water environment is deteriorated, water-supply is in tension, etc. Meanwhile, with rapid development of higher education in China, campus area and scale are gradually expanding, but traditional campus construction has many drawbacks. In order to promote sponge campus planning and construction of universities in hilly areas and provide demonstration windows for sponge city construction, based on deficiencies of campus construction of Hunan City University in the aspect of water resource utilization, we used ArcGis spatial analysis method, simulation method and comparative analysis method on Storm Water Management Model (SWMM) to establish sponge campus construction indexes, content system and optimal design strategies with objectives of campus water safety, water environment and water resource utilization. Results indicate that: difference between sponge campus planning and traditional campus planning mainly lies in rainfall management. We combed the design process of sponge campus planning in hilly areas from the perspective of rainfall management, and simulated the process of sponge facilities controlling the rainfall in the campus via computer model to verify reasonability of sponge facility planning and select the optimal planning and construction plan. This study has defined design process of sponge campus planning in hilly areas to a certain degree and provided a research basis for sponge campus planning and construction of universities, setting up a typical example and driving effects on solving urban local flooding problem and rainfall resource utilization in hilly areas.

Energy demand in hospitals is of highly diverse nature: heat energy, cool energy and electricity. A guarantee of energy supply is required to ensure continuity of medical procedures. Taking care of the lowest possible costs of hospital operations, special attention should be paid to energy efficiency of the installations used in the hospital buildings. The paper presents an analysis of energy demand for heating, cooling, ventilation and lighting in an example hospital in Poland. The selected object was considered a reference as it was built according to a repetitive construction plan, according to which several dozen other hospitals were built in Poland. On the basis of data from 2013-2017, a summary of heat, cold and electricity demand for the hospital in its current technical condition was prepared. Concepts of technical and economic modernization of systems using energy in the analysed facility were proposed, assuming different ranges of changes for individual installations in the hospital. After the analysis of various modernization options, a project was proposed combining the use of heat pumps, photovoltaic installations and generation of heat and cooling in trigeneration, all of which allowed to reduce the costs of operation of the hospital energy systems by about 31%.

Many countries or regions, in recent years, show a rising interest in prefabrication as a “cleaner” production strategy to meet their enormous construction demand, e.g. for housing and infrastructure. Along with this trend is the observation that many governments tend to set forth a high level of prefabrication as a part of their ambitious construction plan. This paper argues that unnecessarily a higher level of prefabrication is better and develops an analytical framework for questing the optimal level of prefabrication adoption in a certain PEST (political, economic, social and technological) background. This framework contains thirteen PEST factors affecting the prefabrication adoption, including policy, supply, labor, social attitude, user acceptance, and so on. These factors in combination will determine the optimal prefabrication adoption level from 0 to 4, which was defined by Gibb 2001 to represent the range from entire cast-in-situ construction to complete prefabricated building, respectively. The framework was substantiated by using Hong Kong's prominent offshore prefabrication construction as a case. It was identified that Levels 2 and 3 are the optimal level of prefabrication adoption subject to the current PEST background in Hong Kong. This paper helps to clarify the prevailing misconception that “the higher the prefabrication level, the better”. The developed framework can be used by other economies to devise their proper prefabrication roadmaps.

The construction of industrial park in the current development model of circular economy has been widely regarded as one of the important modes of macroeconomic exploration all over the world. Therefore, the research on the application of multi-project management theory based on circular economy in the construction of industrial park was proposed in this paper. First, the circular economy and multi-project management theory were expounded in detail. Then, the geographical location of multi project management in Qingyuan recycled plastic industrial park in Guangdong Province and the distribution of each building community were explained. And on this basis, the construction of the park's production, plant areas, residential areas and the planning objectives after completion were analyzed in detail. On the basis of analysis, the multi project management model used in the park was explained. It is pointed out that the construction of the park should be based on its own planning and practical needs, and the appropriate multi project management model should be chosen.

An important decision for policy makers is selecting strategic petroleum reserve sites. However, policy makers may not choose the most suitable and efficient locations for strategic petroleum reserve (SPR) due to the complexity in the choice of sites. This paper proposes a multi-objective programming model to determine the optimal locations for China’s SPR storage sites. This model considers not only the minimum response time but also the minimum transportation cost based on a series of reasonable assumptions and constraint conditions. The factors influencing SPR sites are identified to determine potential demand points and candidate storage sites. Estimation and suggestions are made for the selection of China’s future SPR storage sites based on the results of this model. When the number of petroleum storage sites is less than or equals 25 and the maximum capacity of storage sites is restricted to 10 million tonnes, the model’s result best fit for the current layout scheme selected thirteen storage sites in four scenarios. Considering the current status of SPR in China, Tianjin, Qingdao, Dalian, Daqing and Zhanjiang, Chengdu, Xi’an, and Yueyang are suggested to be the candidate locations for the third phase of the construction plan. The locations of petroleum storage sites suggested in this work could be used as a reference for decision makers.

espanolAlgunas estructuras de contencion de acuerdo con su diseno geotecnico y plan de construccion predefinido. Por supuesto, esto no extrapolable a todos los sitios de analisis, sin embargo, en Brasilia, donde predominan los suelos residuales y lateralizados, se obtienen las mejores resistencias mecanicas en los estratos porosos durante la estacion seca. Esto significa que es controlada por la succion del suelo, es decir, el comportamiento del material presenta una dependencia de la respuesta no saturada del medio. En terminos numericos, para predecir el comportamiento suelo-estructura fue necesario incluir la interaccion atmosfera-suelo en una herramienta computacional, utilizando un modelo hipoplastico. El trabajo detalla de esta manera las simulaciones numericas de una estructura de retencion fundada en el suelo tropical de Brasilia. La estructura fue monitoreada en terminos de desplazamiento, a lo largo de las estaciones locales secas y humedas, y fue simulada por una ley constitutiva calibrada mediante pruebas de laboratorio no saturadas. EnglishSome retaining structures can be designed on a temporary basis, in accordance to the geotechnical design and a predefined construction plan. Off course this may not be valid elsewhere, but in Brasilia, where residual and laterized soils do prevail, best mechanical resistances are obtained in the porous clay setrata along the dry season. That means, it is controlled by soil s suction, i.e. soil behavior presents a dependency on the unsaturated response of the medium. In numerical terms, to predict the soil-structure behavior it is necessary to include the atmosphere-soil interaction in the computational tool, using a hypoplastic model. The paper thus details on this aspect and on the numerical simulations of an existing retaining structure founded in the tropical soil of Brasilia. The structure was monitored in terms of displacement, along local dry and wet seasons, and was simulated by a constitutive law calibrated by means of unsaturated laboratory tests.

Land development and construction activities influence adversely on the ecological environment, in most circumstances. However, the growing awareness of sustainable development and peoples’ willingness to pay for natural landscapes enable developers to gain rather than lose profit from land conservation activities. Therefore, confronting the conflict of land development and land conservation, it is important to understand the relationships between construction plan and its conservation implications as well as economic benefits. This study proposed a framework of conservation construction plan model (CCPM), and three parts of the model framework were represented. Literatures of landscape features and their relationship with housing prices were reviewed, as the basis of model design. This study contribution to the body of knowledge with a set of factors, related to land use structure, landscape environment, conservation value, residential development characteristics, construction density, housing price, etc. which were identified and considered in the model. It also contribute the CCPM to show construction plan scenarios with different land use structures and patterns and to compare the scenarios with changes in economic and environment values, etc. The model framework would contribute to creative construction plans, as a supporting tool for making scientific decisions, preserving land ecological value and maximizing the integrated utility of land resources.

In order to propose an optimised construction plan and prevent and control the possible occurrence of cracks in concrete structures during construction, a detailed simulation of construction stages is required. The temperature and thermal stresses during the construction of a double-hole, double-deck concrete tunnel structure were analysed in this study, in which the analysis of the early-aged behaviour of a structure was performed considering actual construction conditions, and the cracking conditions were predicted. It was found that the temperature trends obtained from the simulated results were in good agreement with actual data, which indicates the reliability of the simulation results. In addition, the distribution of thermal stresses in the structure indicated that the tunnel structure was at risk of cracking at a number of stress concentration areas under the construction conditions. A parameter analysis of different factors, including the initial concrete temperature (25°C, 30°C, and 35°C), formwork stripping time (48 h, 72 h, and 96 h), and the construction season ambient temperature (summer and winter), was conducted. The formwork stripping time did not have a significant influence. It is recommended that the initial concrete temperature should be controlled to below 30°C during construction.

The project team maintains workflow continuity as much as possible to deliver products on time. Nevertheless, poor construction management makes the workflow unstable during the construction process, which leads to the delayed delivery of the building. As different methods to improve production efficiency, Lean Construction and Building Information Modelling (BIM) have a positive impact on the industry. Although many researches have shown the unique advantages of the Last Planner System (LPS) and BIM Technology, the advantages of their integration have not been fully exploited. This paper explores the application of the LPS and BIM in the construction phase through a project that transforms from traditional construction process planning to the use of the LPS. The project results show the impact of the LPS and BIM as lean methods on the project, which can improve the workflow of the construction project by improving efficiency and coordination.

Based on numerical simulations, the heating load reduction effect of an attached sunspace in winter was determined, and the effective heat utilization method and sunspace design were explored. In this paper, we studied the heating load reduction effect using heat from the sunspace and temperature fluctuation of each room at the time of heat use from the sunspace (sending air from the sunspace to the heating, ventilation, and air conditioning (HVAC) machine room and taking the air to the adjacent rooms). In the case of the all-day HVAC system, it was confirmed that a larger capacity of sunspace and not sending air from the sunspace to the adjacent room demonstrated a better heating-load reduction effect. Compared with Model Iw (a house with a window on the exterior of the sunspace opened to external air), Model I (a house with an attached sunspace on the second floor) could save approximately 41% of the total energy. Model II (a house with the attached sunspace both on the first and second floors) could save approximately 84% of the total energy. Sending heat from the sunspace to the adjacent room led to temperature increases in the adjacent rooms. However, if the construction plan is to have the sunspace only on the second floor, the house should be carefully designed, for example, by placing a living room on the second floor.
