경영성과에 영향을 주는 경영환경은 플랜트의 호황에 의한 해외 수주 증가와 국내 주택시장의 침체 등 전략사업부(SBU: strategic business unit)별 명암이 뚜렷하다. 이러한 환경변화는 경영성과 측정 시 전략사업부의 전략적 중요도를 변화시킨다. 그러나 대형건설기업의 경영성과는 전략사업부별 경영성과를 BSC(Balanced Score Card)를 적용하여 일괄 합산하기 때문에 이러한 전략적 중요도의 반영이 어렵다. 이러한 방식은 환경변화를 반영하지 못한 왜곡된 경영성과를 도출할 수 있기 때문에 개선이 필요하다. 그러나 환경변화를 반영한 전략사업부별 비중에 대한 연구가 전무한 실정이다. 따라서 본 연구는 대형건설기업의 전사적 경영성과 측정을 위한 전략사업본부 비중분석을 목적으로 한다. 또한 전략사업본부 비중분석 모델을 제시하여 끊임없는 환경변화에 대응하여 비중을 수정 적용하는 방법을 제시하였다. 비중 분석을 위해 23명의 경영전문가와 실무자에게 설문을 실시하였으며 FD-AHP기법을 적용하여 결과를 정량화하였다. 본 연구의 결과는 전사적 경영성과 측정 시 전략적 왜곡을 최소화하며 환경변화를 반영한 분야별 비중산출을 위한 모델이 될 수 있을 것으로 기대한다.

건설산업의 높은 재해율을 줄이고자, VR 기반 건설안전교육의 도입이 장려되고 있다. 그러나 학습자의 특성을 고려하지 않은 교육방식으로 인해, 학습자의 개인특성에 맞는 효과적인 교육을 수행하지 못하는 한계가 있다. 본 연구에서는, VR 기반 건설안전교육에서 학습성과에 영향을 미치는 개인특성을 분석하는 것으로 목표로 하였고, 이를 위해 머신러닝과 SHAP 기법을 활용하였다. SHAP 분석 결과, 연령이 학습성과에 가장 많은 영향을 미치는 것으로 나타났고, 경력이 가장 작은 영향을 미치는 것으로 나타났다. 또한, 연령은 학습성과와 음(-)의 상관관계를 보이고 있어, VR 기반 건설안전교육의 도입은 낮은 연령에게 더 효과적일 수 있는 것으로 나타났다. 반면, 학력, 자격, 경력은 양(+)의 상관관계를 보였다. 학력이 낮은 학습자에게 더욱 이해하기 쉬운 컨텐츠를 제공함으로써, 학습성과를 향상시킬 필요가 있다. 또한, 자격과 경력이 낮은 학습자의 특성은 학습성과에 영향을 거의 미치지 않으므로, 그 이외의 학습자 특성에 집중함으로써, 학습자 맞춤형 교육 컨텐츠를 제공할 수 있을 것으로 기대된다. 본 연구를 통해, 여러 개인특성이 학습성과에 서로 다른 영향을 미칠 수 있음을 확인했고, 이러한 결과를 활용함으로써, 건설근로자의 개인특성을 고려한 효과적인 안전교육의 기회를 제공할 수 있을 것으로 기대된다.

Through the case study, we surveyed the performance of a CNC-T BAR system on irregular-shaped building construction project. By CNC T-BAR system, we mean a surface curvature control system has been used in aircraft and ship manufacturing by controlling entire surface points on shape. For the past 10 year, the number of irregularly-shaped building design and construction project has been increased, and also the studies on irregular-shaped construction methods have been conducted. However, the previous studies did not review on the performance of the CNC T-BAR system. We collected construction-completed cases in Korea, which applied the CNC T-BAR system, and we studied its performance by comparing with a segment system in terms of construction duration and its quality. The result shows that the CNC T-BAR system can shorten the construction duration comparing with segment-assembly system while maintaining high quality. The CNC T-BAR system is expected to apply on the more number of irregularly-shape building construction project.

Due to unique characteristics of small construction companies, safety management is comprised of complex problems (e.g., resources constraints, a lack of formalized management structures, low level of management safety commitment etc.). In order to understand causal interdependencies between safety factors at different system levels (regulation, organization, technical and individual), this paper aims to develop a system dynamics (SD) model of safety management in small construction companies. The purpose of the SD model is to better understand why small construction companies have low level of safety performance. A causal loop diagram (CLD) was developed based on literature, with an attempt to map causal relationships between variables. The CLD was then converted into stock and flow diagram for simulation. Various tests were conducted to build confidence in the model's ability to represent the reality. A number of policies were analyzed by changing the value of parameters. The value of a system dynamics approach to safety management in small construction companies is its ability to address joint effects of multiple safety risk factors on safety performance with a systems thinking perspective. By taking into account feedback loops and non-linear relationships, such a system dynamics model provides insights into the complex causes of relatively poor safety performance of small construction companies and improvement strategies.

The following conclusions were reached through the research on the development of the required performance extraction tools for the application and utilization of various construction methods of lightweght dry wall. 1) Performance required for walls of apartment buildings can be divided into safety, habitation, durability and productivity. Among these, horizontal load resistance, shock resistance, anti-seismic performance, insulation, and acoustic characteristics are the main performance that correspond to dry walls. In addition, safety related to toxic gases and contaminants are required according to recent eco-friendly requirements. 2) To select a wall according to the required performance of an inner wall applied to an apartment, a map tool in the form of 2D matrices was constructed to enable the required performance to be applied, indicating that the wall location and wall material and its differentiating according to the old method.

Best value in value engineering has relation to cost and performance. But a severe problem in VE study of a project is to reduce value due to loss of performance, caused by focusing on cost reduction. Also a lack of understanding performance concept, no trial VE workshop as well as cost saving-based policy have not satisfied customer needs. A efficient and practical methodology for accomplishing best value in construction projects is proposed. This study developed a more objective approach for performance measurement approach of mega projects and suggested a systematic process of performance quantitative analysis verifying value improvement. The proposed performance measurement method would be very useful for better communication and consensus between stakeholders and VE team especially through value engineering.

For the target goal of Zero-energy House construction in 2025, the government announced that the insulation regulations will be continuously enhanced. It has been predicted that high-performance insulation materials, such as vacuum insulation panel (VIP), should be used to decrease the thickness of outer walls. The aim of this study was to evaluate the performance of adhesively fixed external insulation and finish system (EIFS) with VIP. The energy performance of a base model with conventional internal insulation system and three alternatives of EIFS with VIP were analyzed by three-dimensional heat transfer simulation. Construction cost and convenience of each alternative were also evaluated and compared. As results, effective alternatives in terms of each performance as well as overall performance considering the weighting factors of each performance were suggested.

The attention in construction Automation is getting higher since it could be the answer to the lack of skilled labor by decrease in construction population and aging which adversely affects productivity and quality in the construction site. We are on the way to develop a construction automation system adequate for domestic circumstances in Korea; it is called RCA(Robotic-crane based Construction Automation)system. Climbing hydraulic robots system is a part of RCA system and makes Construction factory(CF) climb through the guide rail on the core wall. The safety of climbing hydraulic robots system is at issue due to the overloaded weight of CF. Preventing this issue, present study did the design verification through the structural analysis and the simulation. Mock-up test also was done to analyze the drive performance of climbing hydraulic robots system.

Using the CSI(Construction Safety Management Integrated Information) data, a comparative analysis was conducted by work type and construction cost according to whether the construction sites were subject to making a safety management plan or not. As a result, by type of work, the ratio of deaths in non-plan sites was high in mechanical facilities and earthworks, and the operation performance of the system was much higher in sites that were less than 5 billion won of construction cost.

본 연구는 중소(지방)건설업체의 효율적인 공정관리와 국내 건설 산업의 성과관리를 위한 시스템 구축을 목적으로 한다. 린 건설의 공정관리 프로세스를 탑재한 시스템은 Web 2.0 플랫폼을 기반으로 프로젝트에 참여한 수많은 원도급업체와 협력업체의 클러스터를 생성하여 상호 유기적인 공정관리를 가능하게 할 것이다. 또한 프로젝트 진행 중 발생되는 수많은 데이터를 수집/축적하여 프로젝트가 진행 중이거나 종료 된 후 이를 분석하여 프로젝트의 성과관리에 대한 비교가 가능 할 것이다. 이러한 성과관리 사례들은 차후 실행되는 유사한 프로젝트의 공정계획에도 도움이 될 것이다. 본 연구의 기대효과는 Web을 통한 공정관리로 인해 국내 중소(지방)건설업체가 느끼는 복잡한 공정관리 및 시스템 구축에 따른 부담감을 조금이나마 덜어 줄 것이며, 데이터베이스에 축적되는 방대한 양의 신뢰도 높은 데이터로 보다 정확한 성과관리를 할 것으로 기대된다. 그리고 더 나아가 공정관리뿐만 아니라 설계, 감리, CM 등 폭 넓은 데이터베이스 구축을 통해 건설산업의 경쟁력 향상에도 기여 할 것이다.
