This paper presents the core technology of Construction Business Process Automation to model and automate construction business processes. Business Process Reengineering (BPR) and Automation (BPA) have been recognized as one of the important aspects in construction business management. However, BPR requires a lot of efforts to identify, document, implement, execute, maintain, and keep track thousands of business processes to deliver a project. Moreover, existing BPA technologies used in existing Enterprise Resource Planning (ERP) systems do not lend themselves to effective scalability for construction business process management. Application of Workflow and Object Technologies would be quite effective in implementing a scalable enterprise application for construction business processes by addressing how: 1) Automated construction management tasks are developed as software components, 2) The process modeling is facilitated by dragging-and dropping task components in a network, 3) Raising business requests and instantiating corresponding process instances are delivered, and 4) Business process instances are executed by using workflow technology based on real-time simulation engine. This paper presents how the construction business process automation is achieved by using equipment reservation and cancellation processes simplified intentionally.

Coarse aggregate is produced in various ways depending on the location and production method. Currently, the construction industry is in need of a stable supply of coarse aggregate and a way to secure standard quality. The purpose of this study is to examine whether the use of coarse aggregate in 3D printing can help solve this problem. ABS filament was selected for use in 3D printing. CATIA was used for the design of the coarse aggregate, and CUBICON Single Plus was used for the production. Six specimens were produced and cured in water for 28 days. Three of them were made with AE agent, and three were made without it. A compressive strength test confirmed that when the AE agent was used, the compressive strength was greater than the lightweight concrete design criterion specified in the concrete standard specification. This suggests that coarse aggregate produced by a 3D printer may be used for lightweight concrete. A mass production system using this method could help to solve the problems facing the construction industry, such as stable supply and demand for coarse aggregate and securing standard quality.

The government is promoting the reorganization of the construction indusrty under the theme of reorganizing the production system. However, it has been pointed out that this is contrary to the increasingly specialized and technical skills of the landscaping field. Therefore, it is urgent to respond to the construction industry integration policy and improve an appropriate work system and the content of the landscape field. Therefore, this study investigated the intention of the industry to reorganize the production system and the production structure of the landscape field, so that it can be used as a reference for future changes. As a result of the survey, 1) the perception of the reorganization policy is a highly requesting step-by-step promotion that reflects the industry's will, 2) the system is divided into generalization and specialization and is highly opposed to integration, 3) appropriate design and construction costs are the most important directions for improving landscape construction projects, and 4) reestablishing the relationship with related civil engineering works is important for improving detailed construction types. Overall, it was pointed out that the current specialized landscape construction does not sufficiently reflect the changing landscape business and is only appropriate for subcontractors in other industries. Therefore, it is necessary to promote policies that reflect this. In the long run, it is urgent to establish the status of landscape construction as an independent object, and it is necessary to supplement the legal system and change the industry accordingly.

The proportion of elderly people over 50 years old in the total population of Korea increased from 29.2% in 2010 to 34.8% in 2015. As a result, the proportion of construction workers over 50 years old compared to the total construction workers increased from 20.1% in 2010 to 27.0% in 2015. In this aging society, the construction industry has faithfully carried out the business objectives and budget execution of measures to prevent disasters against elderly workers, but there was a limit to the fundamental prevention of disasters. Because the countermeasures for the prevention of construction disaster are considered on all ages rather than elderly workers. This study investigates the safety and health status of elderly workers at construction sites and suggests the plans to reduce disaster. In particular, to reduce disasters of rapidly growing elderly workers, the authors reviewed the related literature and safety regulations, statistics on the causes of industrial accidents, statistics on the status of industrial accidents, and applied to 3,549 workers who participated directly in the construction activities. The authors surveyed the actual situation of safety and health, presented the comprehensive disaster reduction measures by analyzing the current status and problems of disaster prevention projects. If the countermeasures proposed in this paper can be reflected in the actual policy, it is expected that the countermeasures will be possible to reduce the disaster of the elderly workers at the construction site, which is gradually increasing.

The government wants to apply the construction cost estimating method based on historical data published in the first six months of 2004. Construction companies, however, require the proposed cost estimation model, to be improved which makes it difficult to predict a reasonable construction costs. This paper presents an improved historical data selection model after analyzing the problem of previous method throughout comparing contracted unit prices of reinforced concrete works selected by the previous model to market prices. The model which can select more feasible data would assist participates such as general contractors and sub-contractors to earn a proper profits.

In domestic construction industry, now demand for airport facilities, gymnastic facilities, mass meeting facilities, sales facilities is increasing. Because of this, demand for huge space is also increasing. In making huge space, existing PEB(Pre-Engineered Building) and Pipe Truss, As span is lager and larger, steel weight is increasing and hard to apply for large span. For solving this problem, Many program was proposed, and in that Space Frame was rising. But in domestic construction there are very rare practical use for Space Frame. In this study, we wish to introduce Space Frame that has several advantages in construction expense, construction time, constructibility and also with analyzing example for applying Space Frame, wish to investigate characteristic of Space Frame. Go forward better, through comparison of other different old method and basic character of Space Frame, confirm advantage of Space Frame that have infinite development possibility and revitalize the Space Frame in domestic study and further more wish to raise practical use for Space Frame.

예상은 하고 있었던 일이지만, 준비없이 갑작스럽게 다가온 1993년 중국과의 국교정상화는 우리에게 무의미한 대가를 적지않게 하였다. 그리고 이후 이미 8년이란 세월이 흘러갔어도 잘못 끼운 첫 단추의 부담은 여전히 해결하지 못한, 아니 어쩌면 영원히 해결할 수 없을 것만 같은 숙제로서 남겨져 있다. 특히 손상된 민족의 자존심은 경제적인 실리를 떠나서 제2의 조공시대를 방불케 하는 신사대주의의 한중관계를 만들어 버리고 말았다. 최근 들어 IMF이후 주춤했던 중국을 향한 건축계의 막연한 기대가 2010년 북경의 올림픽 유치확정을 계기로 서서히 달아오르는 느낌을 받는다. 게다가 일부 언론매체의 보도는 벌써부터 앞으로 발주될 100억 달러 이상의 건설시장경기를 들먹이며 우리의 떡이 어느 정도인지 저울질하는 웃지 못할 모습을 보이고 있다. 물론 의욕과 열정을 무조건 탓하는 것도 잘못이지만 일에는 순서가 있는 법이며 지나친 무리수는 결과적으로 과역과 과열이라는 쓰라린 경험을 남기기 십상이다. 지금 이 시점에서 우리가 할 일은 분명하다. 우리의 현실을 직시하고 저들의 현실을 정확히 파악하며 국제적인 추세를 냉철하게 읽어내는 것이다. 중국의 건설시장에 관해서는 이미 1995년 12월호 '건축'잡지에서 '중국의 건축'이라는 특집을 통해 부분적으로 소개된 바 있고, 2001년 9월호 '건축인'에서도 '중국건축:건설시장, 아직도 기회는 있는가'라는 주제를 다룬바 있다. 뿐만 아니라 일부 설계사무소가 자신의 실제 작업경험을 다양한 지면을 통해 간헐적으로 소개하는 한편, 지금 이순간에도 자신들 나름대로 중국건축업계와 협력관계를 구축하여 진행하는 일이 적지 않다. 이 글은 우리나라의 대표적인 건축설계사무소 가운데 하나인 (주)무영종합건축사사무소가 중국시장에 진출하는 과정(즉, 이 과정은 비교적 총체적인 것임)에서 얻은 경험을 진솔하게 밝혀 한국건축계의 동료들과 자료를 공유하여 동일한 오류를 범하지 않도록 하고자 하는데 그 근본적인 목적이 있으며, 참고로 최근 중국 건설시장의 동향을 가능한 한 상세하게 소개하고자 한다.
