Analysis of Management Methods and Construction Standards for Resettlement Housing Projects（安置房工程项目管理的办法及施工标准分析）

With the rapid development of science, technology and economic strength in China, the construction industry has developed vigorously. Construction safety and quality management is a systematic project. The quality of construction will directly affect the safety of people's lives and property and the stable development of society. Construction quality and safety is the key to the success of construction projects. It is the fundamental guarantee to maintain the corporate image and obtain long-term economic benefits. Safety-critical system design needs to be guided and evaluated by security analysis. Fault tree based on binary decision graph is one of the commonly used methods of safety analysis in engineering. The risk assessment is based on the risk factor and the simulation application environment design experiment is performed. Correctly handling the relationship between construction safety and quality management plays an important role in the smooth completion of engineering projects and the stable development of society.

Construction industry is one of the most hazardous industries to work in. This problem is further exacerbated by the fact that safety performance improvement is stagnating. Information technologies (ITs) are however identified as one of the most promising methods of improving the performance of construction safety. The goal of this paper was therefore to present previous research in the application of innovative ITs to the field of construction health and safety (H&S), classified by their underlying technology and application, to identify research gaps, as well as to evaluate and describe the potential of their implementation into construction safety practice. To achieve the set goals, the research consisted of identifying and studying the existing research published in the leading journals in the field of construction H&S. The review identified 72 papers dealing with development or application of innovative ITs. The research had also identified several research gaps, which have a significant impact on the construction safety practice. These gaps focus on the construction phase, while neglecting earlier project phases; industry and project levels, while neglecting construction activity and task levels; building projects, while neglecting infrastructure projects and specific hazard types, while neglecting a universal approach. Focussing research effort on these gaps would benefit all construction safety stakeholders but mostly the prominent contractors and H&S professionals. Furthermore, recommendations for directing research focus on solving the identified issues are given in this paper.

The reasonable implementation of mechanical and electrical manufacturing, installation and construction technology has an important impact on the orderliness and rationality of construction engineering construction. Due to the great complexity of mechanical and electrical manufacturing and installation, the installation and construction technology should be rationally selected in order to ensure the installation quality. In addition, construction cost, construction schedule, construction safety and construction quality should also be considered in the mechanical and electrical manufacturing and installation construction tasks, so as to improve the quality level of installation engineering. This article is mainly to analyze and study the basic work of mechanical and electrical manufacturing and installation construction technology.

With the continuous development of society and the improvement of people's living standard, the construction scale of construction project is increasing and the construction period also increases. In the construction process, the weather changes are often one of the key factors aff ecting the progress and quality of the project. Rainy season construction is the inevitable problem in the construction process, the rainy season construction facing rain, wind, high temperature and other adverse environmental factors, and can directly endanger the production safety, to the enterprise to bring immeasurable losses, so science reasonable organization of construction, to take security technical measures, and actively respond to the rainy season construction of various dangerous situations, to improve the ability to resist risks, to ensure the safety of production, is of great signifi cance. Based on the theory of construction safety management and the characteristics of rainy season, this paper analyzes and controls according the experience and technical characteristics of engineering construction. To ensure the progress and quality of construction and the safety of construction, the principle of minimizing the loss, put forward the corresponding maintenance measures to enhance the safety of the rainy season construction, to enhance the economic interests of enterprises.

This article deals with resettlement management in Indonesia, which involves a number of policy and implementation issues concerning land acquisition, compensation, and resettlement practices in development projects.1 The principal objective of this article is to identify a set of policy measures gleaned from past experiences in Indonesia and to present a comparative review of how other countries have addressed land acquisition and resettlement issues, including the latest donor policies concerning resettlement of people affected by the development processes. Several resettlement case studies in Indonesia are briefly presented to identify past mistakes and successes. The Indonesian experience is then assessed in the light of international “best practices” for retooling policy, including adoption of an appropriate resettlement policy in Indonesia. The role of local government bodies, non-government and community-based organizations in resettlement management and their beneficial involvements in resettlement planning and implementation is briefly discussed.

Earthfill dam construction requires effective strategies to ensure structural safety, construction quality, and efficient use of time and resources. This study examines the construction strategy and implementation method of the Main Dam of the Bagong Dam Project, Indonesia, which is designed as a vertically zoned earthfill embankment with a length of 620 m, a crest width of 12 m, a crest elevation of +330 m, and a height of 82 m. The research focuses on the application of a zoning-based construction approach to improve construction efficiency under complex field condition. The results indicate that dividing the embankment into six functional zones enables systematic layer-by-layer construction and parallel work execution, resulting in a planned construction duration of 937 working days. The integration of material zoning, quality control procedures, and optimized equipment management ensured that all embankment layers achieved more than 95% of maximum dry density. Coordinated equipment utilization further improved productivity, allowing approximately 304,653 m³ of embankment work to be completed within 53 working days during critical construction stages. In addition, the implementation of a structured safety management system supported the achievement of zero-accident construction performance. These findings demonstrate that the integration of zoning strategy, systematic construction sequencing, quality management, equipment planning, and safety control significantly enhances time and cost efficiency while maintaining construction quality. The proposed approach provides a practical framework for earthfill dam construction projects in Indonesia and other regions with similar geological and climatic conditions.

Large-scale land acquisition projects by foreign investors, also known as “land grabbing,” raise difficult questions about the processes of valuing land in Sub-Saharan Africa that the current literature does not sufficiently explore. Land acquisitions can help developing countries like Tanzania achieve their economic and development goals. Nonetheless, it can also threaten local livelihoods and well-being due to displacement, lack of access to natural capital, and conflicts between land users. Empirical evidence is limited on how local contexts affect the recognition and incorporation of multiple values that people hold about land into decisions on land acquisition projects in Tanzania. Plural valuation (PV) is needed to design more comprehensive and deliberative policy instruments that enhance nature’s contributions to people. This empirical study uses sociocultural valuation approaches to assess the diverse values of land in the Bagamoyo district of Tanzania, impacts of EcoEnergy land acquisition project on local livelihoods, and contextual factors that enable or hinder incorporating PV into decisions. The findings suggest that synergies and conflicting values of land exist, and PV can serve as a negotiation support tool to reconcile the differences and land conflicts. The success of PV relies on the (1) extent of partnership and participation, (2) design of asset valuation process, (3) stakeholder goals, and (4) sociopolitical context. Currently, the risks of land acquisition projects outweigh the benefits to people in rural Tanzania. However, to realize the sustainable and equitable flow of the contributions of land to Tanzanians, the government should consider improving the valuation processes by (i) fostering recognition of neglected voices and marginalized people, (ii) rectifying power imbalances and injustices that result from current land valuation processes, (iii) reinforcing customary land rights and compensation policies, and (iv) adhering to the principle of free, prior, and informed consent.

Understanding land-expropriated farmers’ welfare change and the determinants of their willingness to change is very important for sustainable urbanization and social stability in developing countries. However, this issue has been seldom explored in previous studies, especially in China. This paper aims to enrich this field by conducting an empirical study using a household survey in 2014 in Nanjing, a major city in the Yangtze River Delta. The impacts of land expropriation on the variation of land-expropriated farmers’ employment and inhabitance are explored, while the determinants of land-expropriated farmers’ willingness are estimated using ordered logistic regression. Results show that the land-expropriated farmers pay more attention to the changes of employment and inhabitance after land expropriation, rather than land expropriation itself. While employment aspects were key determinants of the farmers’ willingness in 1996, factors relating to inhabitance aspects have become more important nowadays. Moreover, it is necessary to grasp the changing rules of land-expropriated farmers’ interest appeals in order to adjust the compensation and resettlement policies according to local conditions. Thus, this will improve land-expropriated farmers’ willingness. Meanwhile, the government should create a better expectation of employment and inhabitance after land expropriation for farmers. Furthermore, the government should also build a land expropriation information sharing and feedback mechanism in addition to improve the employment and housing security system.

Design/Bid/Build (DBB) delivery is the traditional approach for establishing the least cost for building projects, but other alternative project delivery methods have become increasingly popular. Although multiple studies have compared delivery methods for vertical construction, there have not been any comprehensive studies quantifying how delivery methods compare specifically for repetitive commercial construction. This research utilized a mixed methods approach to compare the cost, schedule, and quality of Construction Manager/General Contractor (CM/GC) delivered projects with DBB projects for repetitive commercial construction, using 173 facilities built with the same base floorplan. A comprehensive quantitative comparison was conducted, excluding potential confounding variables and including short- and long-term direct and indirect costs, construction time, and quality assessment scores. Contractors and project managers were also surveyed regarding their perceptions of CM/GC process effectiveness in a repetitive construction environment. This research demonstrated that the CM/GC delivery method was more effective for repetitive commercial construction, uniquely quantifying the relative cost, schedule, and quality improvements of CM/GC delivery over DBB projects. Compared to DBB, CM/GC projects produced total construction cost savings of 5.4%, a 20% shorter construction cycle time, consistently higher quality assessment scores, and an overall reduction in repair costs of 34%.

This article discusses the reconstruction of land acquisition and compensation policies for the public interest from the perspective of the value of justice in the context of Indonesian land law. The research method used is qualitative, using literature study and document analysis as data sources. This approach allows for a deep understanding of the dynamics and challenges in land acquisition and compensation to affected land owners. In the context of policy reconstruction, this article analyzes the steps required, including identification of needs, evaluation of existing policies, and formulation of new policies or updating existing policies. Factors influencing the policy reconstruction process are also studied in depth, including political, economic, social, cultural and legal dynamics. In addition, this article highlights the mechanism for land acquisition for public purposes and the process of compensation to affected land owners. In this context, the perspective of justice values becomes the main focus, by evaluating ethical, moral aspects and principles of justice in providing compensation to land owners. This research is expected to provide an important contribution to understanding the importance of justice in the reconstruction of land acquisition and compensation policies for the public interest in Indonesia

Deep foundation pit excavation is a basic and key step involved in modern building construction. In order to ensure the construction quality and safety of deep foundation pits, this paper takes a project as an example to analyze deep foundation pit excavation technology, including the nature of this construction project, the main technical measures in the construction of deep foundation pit, and the analysis of the safety risk prevention and control measures. The purpose of this analysis is to provide scientific reference for the construction quality and safety of deep foundation pits.

Analyzing the organizational and legal concepts of state risk management in construction, during the decentralization reform in Ukraine, attention is focused on the overall impact of risks arising from the partial delegation of managerial powers to local authorities and those directly related to the state administration of risks in the field of construction and operation of structures. It is well-proven that every region has the priorities in the management of building risks and they can conflict with not only interests of other regions but also public policy. It can result even in bankruptcy of territories, when every region will defend the interests in relation to a management risks and inculcate the own system of self-regulation of town-planning activity in a region. Presently the process of scientific research and study of level of offensive of risks in building, depending on the regional features of territory, remains a white spot in planning of activity of organs of local-authority. The question is about forming of practice of state administration risks which test changes, in building as a result of decentralization of power, as a result of leadthrough of row of marketings researches, both into industry and at the oversea market. It is noted that the result of decentralization reform could be better if the necessary constitutional changes were voted for to develop the local level of government. The author substantiates the provision that the main tasks of public authorities in the sphere of construction and operation of facilities, with decentralization, are: the territorial organization of power to ensure the reliability and safety of construction and operation facilities; the establishment of requirements for regional policy reforms that must ensure proper conditions for the functioning of construction enterprises; ensuring the proper scientific and technical level and quality of construction and operation of facilities; state management of lands, natural resources, environmental protection, rational use of land and natural resources, saving material, energy and labor resources and others. An organizational and legal mechanism for the adoption of public-management decisions in the sphere of state construction policy has been developed and its advantages have been revealed.

The Tunnel Boring Machine (TBM) technology has significant advantages over conventional Drill & Blast method, and it has become one of the most common tunnel excavation methods in the world. However, weaknesses of TBM such as the poor adaptability to complex geological conditions create a bottleneck in its functionality, and restrict its further development. Therefore, factors such as engineering geological conditions, construction schedule, cost, environmental impact and other multi-disciplinary influences should be well considered in the TBM selection. This paper presents the capabilities, limitations and challenges of TBM method by a study of various case projects, and proposes effective countermeasures towards bad geological conditions. The results of this research are helpful for improving the TBM working efficiency and ensuring a smooth and safe construction.

Innovation is an imperative in all industry sectors. For those such as construction, which are not considered high-tech and which operate as one-off projects, the uptake and diffusion of new innovations into ongoing practice across projects pose particular problems. The nature of these problems faced at a project level needs to be better understood. This thesis is an exploration of innovation implementation in the context of Project-Based Engineering (PBE). It is an empirical investigation of how new planning technologies are implemented in major infrastructure construction projects and the barriers that prevent such implementations from being effective. The findings of this investigation are used to develop and evaluate a new model of innovation implementation in this context. The research design is centred on the immersion of a participant-observer in seven live construction projects over a period of 3.5 years. Each project studied was implementing the same innovation: 4D CAD modelling (3D design model + the construction schedule). A wide cross-section of data was gathered in the field including direct observations, documents and other work products from participation, email and other correspondence associated with the 4D CAD implementations, and formal and informal discussions with project-participants. These data were analysed using content analysis software to find patterns. The research was iterative and involved three phases. The initial phase was a pilot study of implementation in practice using the data from one project. It produced rich descriptions of what transpired and a critical comparison with accounts from the literature. This led to a series of propositions about the influence of project-participant perceptions that were synthesised into a new theoretical model: the initial Perception-Influence model (P-I1 model). The middle research phase then developed this model iteratively using a more-focused data collection and content analysis across four construction project organisations. This was done to provide supporting evidence for the theoretical constructs in the P-I1 model as well as to refine them and add new ones. The outcomes of the middle phase were the P-I2 and P-I3 models. The final research phase analysed the data from the last two project organisations in terms of the P-I model framework with a view to evaluating the model’s theoretical significance and practical applications. The P-I model shows that negative perceptions of value, benefit and usability can cause an innovation implementation to be ineffective as a result of discontinued use or neglect. It provides a map for the progression of an implementation using the perceptions and actions of project-participants as primary constructs. The model proposes that each perception is formed by a number of contributing factors or secondary constructs synthesised from implementation research and user acceptance literature, for example, an opinion or concern about how much an innovation costs (i.e. transaction costs). It also proposes that each perception has both a positive and negative associated action. The constructs that make up the P-I model are grounded in the empirical data. This is because the actions, opinions and concerns of project-participants observed in live projects are evident in project documentation such as emails. These two sources (i.e. observations and project documentation) provide data sets that were used to triangulate inferences about the perceptions of project-participants and the outcome of each 4D CAD implementation (i.e. effective or otherwise). This aspect of the research was not only important for the recommendation of potential applications for the P-I model but also during its conception, development and evaluation. The P-I model is a new and important perspective for both implementation research and PBE practitioners. It helps satisfy the calls for studies of innovation implementation that focus on factors at an individual level and those asking for a better understanding of innovative behaviour. This work shows PBE practitioners how the perceptions of project-participants can have a major impact on the effectiveness of an innovation implementation. The findings provide an evidential basis that can improve implementation effectiveness, especially in PBE organisations. The knowledge built into the P-I model can also assist the planning and execution of innovation implementation strategies, aid in the assessment and redirection of those in progress, and help document lessons learned for implementations within project organisations that have been previously completed. This research uses the P-I model to open the way for future empirical studies of innovation implementation in PBE contexts beyond construction. These would also provide data to further refine the constructs in the model.

Research in Establishment of Quality Control and Risk Management Systems Jacob Chen; Jieh-Haur Chen Pages 323-328 (2011 Proceedings of the 28th ISARC, Seoul, Korea, ISBN 978-89-954572-4-5, ISSN 2413-5844) Abstract: If all data, records, checklists and photographs accumulated during quality checks and labor safety inspections at construction sites are not systematically arranged, stored and tracked. The status of improvements is not confirmed and tracked in a timely manner, not only will engineering quality and construction safety be influenced but work load at construction sites will increase. In view of the above scenario, development of a quality control (QC) and risk management system is a matter of priority. The quality control and risk management system we developed focuses on streamlining time and human resources at construction sites to reduce costs, and improve the quality of construction and health and safety practices. In a plan-do- check-action (PDCA) cycle, the system passed efficiently the two procedures, check, and action, to improve the implementation capability in construction sites and competitiveness in the market.
