건설 신기술은 현장적용에 대한 불확실성, 기술적 우위의 확신결여 등으로 활성화가 어렵고 신기술 활용실적은 미흡하다. 따라서 건설신기술 현장 적용에 따른 문제를 해결하기 위해 신기술 예측자료가 필요하며, 성능평가 모델이 요구된다. 본 연구의 목적은 의사결정도구로서 건설시뮬레이션을 활용한 신기술의 현장 적용시 예측되는 생산성과 비용을 평가할 수 있는 방안을 도출하는 것이다. 이를 위하여 시스템 철골계단 공법을 선정하였다. 본 공법이 실제 적용 중인 현장에서의 데이터 수집을 기반으로 건설시뮬레이션을 적용하였으며, 이에 본 계단 공법의 1개층 1개소 설치에서부터 6개소 설치 시의 다양한 사례에 대한 시간당 생산성 및 단위비용을 예측하였다. 위의 과정을 통하여 건설시뮬레이션 기법은 현장데이터가 부족한 건설신기술의 현장적용성 평가를 위한 적용의 가능성을 제시하고 있음을 알 수 있다.

The object of this research is to develop a simulation system for earthmoving operations in consideration of the impact of congestion in-between equipment and existing traffic flow around the site. The congestion in-between equipment and traffic flow affect work productivity. The conventional discrete event simulation, however, has limitations in simulating the flow of construction equipment. To consider the impact of congestion in-between equipment and existing traffic flow, in this paper, a multi-agent based simulation model that can realize characteristics of truck behavior more accurately to consider the impact of congestion was proposed. In this simulation model, multiple agents can identify environmental changes and adapt themselves to the new environment. This modeling approach is a better choice for this problem since it describes behavioral characteristics of each agent by sensing changes in dynamic surroundings. This study suggests a detailed system design of the multi-agent based simulation system.

Recently, with the increasing of construction works, large construction equipment are used to reduce the term of work and labor cost in construction field. Therefore, construction equipment noise has caused much annoyance for a number of dweller in nearby construction field and it has become a very serious problem in our living environment. Nevertheless, in our country, adequite guidelines for the construction equipment noise are very deficiency because of the lack of basic data and insufficient research works. From this point of view, this study attempts to survey the characteristics and prediction of SIP piling noise. On the basis of measurement value, we analysed about prediction possibility of SIP piling noise by computer simulation.

In order to shorten construction duration in high-rise project, construction company tried to make various system method toward simplifying construction method and shortening construction duration. Though high-rise tower-type residential project are growing, there are few case study. Then, the data for preliminary schedule planning in high-rise tower-type residential project are rare. This purpose of research shows construction method in structural work in high-rise tower-type residential project, suggests schedule planning in structural work through case studies. The structural work in high-rise tower-type residential project was divided 1) completion of form in lower part and 2) the typical floor under penthouse. The statistical analysis were done in two parts, the data from analysis were used in simulation. Finally, researcher confirmed the difference between real construction duration and the figure from simulation. The results shows that the more construction duration is long, the less ACS's cost is low. It means the effectiveness is increasing in ACS, if the floor number is high.

It is an important issue in cost management to contract with the standard of cost estimate by the reasonable way in public construction projects. For the standard of cost estimate based on the Standard Estimating System, there is a difference of labor inputs between Standard Estimating System and actual quantities in construction projects. The duration of form work in multi-family housing depends on the manpower compared with other work, which is the critical path on the schedule management to be decided quality, and is the important to the cost management of construction projects. This study presented a simulation model of the productivity analysis for selecting the standard work type of form work in Multi-family housing construction projects.

Simulation is becoming increasingly popular in construction for training, planning and for assessment of projects. There are, however, significant problems inherent in simulating construction which are not common to other simulations. This paper describes the development and use of computer-based game for teaching and learning of some aspects of construction project management. It is concerned with the development of a model used to simulate the construction of a rock- and clay-fill dam. It includes detailed physical modelling of the performance of individual pieces of equipment and their interaction with the ground, the geography of the project and the weather in which the equipment operates. The behaviour of all of the individual pieces of equipment when acting as fleets is also discussed. The paper also describes the modelling issues of non-technical aspects of earthmoving operations. These include environmental impact, safety, quality and risks. The problems of integrating these with the physics-based models of the equipment performance are discussed. The paper also draws on real experience of using the game in classes in three universities in different countries.

건설공사의 시공공정을 관리자의 경험적 판단에 의하여 작업팀을 구성하여 운영하면, 시공공정의 진행이 비효율적으로 될 가능성이 많다. 그러나 시공계획단계에서 모의조작을 통하여 자원할당, 공사비, 공사기간의 최적 안을 산출하면 시공공정을 정량화하여 효율적인 운영을 할 수 있다. 본 연구에서는 시공공정을 계획할 때 작업팀 운영의 변화에 따른 자원할당 변동치, 자원 손실비, 총공사비, 공사기간의 최적 안을 모의조작 할 수 있는 수식모형의 시안 식을 제안하였다. 제안된 수식모형을 검증하기 위하여 시공공정의 수평작업역과 수직작업 역이 각각 상이하게 구성된 공동주택 골조공사에 적용하여 시현하였다. 본 연구에서 제시된 수식모형을 적용하여 모의 조작을 실시한 결과가 실제 사례공사에서 적용된 작업팀의 운영실적보다 효율화를 달성하였다.

This study investigates the virtual reality (VR) simulation to train construction workers for modular construction. Recently, the construction industry has been experiencing a growing demand for modular construction due to a shortage of labors and an increasing social need for safety. While the demand for modular construction has been increasing, construction labors suffer a basic knowledge regarding modular construction. The users of the simulation, developed by Unity program and Oculus Quest 2, experience the removal of hazardous elements at the location whether the modular unit suspended by a crane is lowered, the lowering and assembly of units through crane operation, and the fall from the roof which is the most frequent accidents in modular construction. The simulation was tested by 15 subjects. The effectiveness of the education was measured through a survey on self-efficacy, perceived usefulness, usability, and presence. It was found that the VR training is suitable for educating on the modular construction activities and safety issues related to them. This study also found that perceived usefulness is the factor that has the greatest impact on self-efficacy. This study can contribute to resolving the labor education issues for the deployment of modular construction.
