3D printing technology in the construction field is currently being developed and commercialized actively in foreign countries, but the development of material and equipment is underway as an initial research stage in Korea. It is necessary to implement commercialization through the introduction of 3D printing technology in the construction field as soon as possible in Korea, but there is no guideline for suitable equipment and materials in Korea at present. Therefore, in order to help prepare for commercialization, it is necessary to provide data such as equipment size and materials suitable for commercialization at the initial stage. This study investigates the types, specifications, and applications of equipment that are being used overseas to provide the equipment type and material cost required in the initial stage of commercialization in Korea. Using the surveyed data, it was possible to calculate the advantages and disadvantages of the equipment type and specification, and the cost of materials used. As a result of the analysis, Gantry type is suitable for the domestic commercialization, and the standard of the output area is $100m^2$ and the extrusion amount of $250m^3/sec$ is proposed, and the material cost of the commercial product is 20thousand won. The suggestions in this study will help to plan the construction of products and equipments to commercialize 3D printing technology in construction field in the future.

In this paper, the present condition for localization of process pumps and the enhancement method of the localization ratio of process pumps for refinery and chemical plant market were studied. The market of plant industry in the world has grown rapidly since 2000. However, the profit of domestic plant EPC compaies cound not have been increased as much as the market scale because they procured most of equipment from overseas. To make remarkable profit of plant EPC companies in the petrochemical industry, localization of equipments is required. Suitable equipment for localization is process pump applied API 610 standard. An purchased amount of pumps from overseas by domestic plant EPC companies in the last two years were 230 billion won. If process pumps are localized then an profit of plant EPC project will increase.

Hydrogen is considered a key energy source to achieve carbon neutrality through the global goal of 'Net Zero'. Due to limitations in domestic green hydrogen production, Korean companies are interested in importing green hydrogen produced overseas. Because Australia and the Middle East possess high-quality renewable energy resources, they are attracting attention as suitable regions for producing green hydrogen using renewable energy. The cost of constructing and operating a green ammonia plant varies depending on the region. In this study, an economic feasibility comparison of green ammonia plant construction in Australia and the Middle East is conducted. Through this, it is expected to contribute to the economic analysis and feasibility analysis of the project to import hydrogen in the form of green ammonia into Korea.

The concept of construction information systems (IS) is very comprehensive and subjective. Acronyms in relation to the construction IS may include BIM, CIC, IT, nD-CAD, ERP, CALS, KM and so on. These terminologies are used in a somewhat mixed way causing possible misunderstandings in research and practice of construction information systems. Moreover, ever-changing construction business environment has widely affected the roles and methods of utilizing construction IS. Examples of these changes are dissemination of alternative project delivery systems, global standardization under highly competitive overseas market, and advancement of information and communication technologies. In this context, the purpose of this paper is to propose a high-level framework for information systems in the construction industry. Several different concepts in the area of construction IS were investigated first in order to identify the major variables of the framework. Trends of research and real-world implementations were then analyzed to support the rationale of the variables. Finally, a framework was proposed by re-arranging the relevant issues. Findings of this paper indicate that different acronyms commonly share many similar concepts in their definitions, however, in each acronym, the motivations and approaches to implementing construction IS are very different. Different approach can provide maximum effectiveness, while overlaps may happen causing practical inefficiency.
