Construction companies can easily understand present noise condition of their construction site via C-Noise. C-Noise is noise simulation software that simple to use. Construction companies spend time and cost for public complaints about construction noise. Construction site noise management using noise simulation software like C-Noise can reduce public complaint. achieve cost reduction to treat it.

This paper describes the use of a highly interactive and inter-operative application for complex simulation environments, or Synthetic Environments (SE), as deployed for construction as Construction Synthetic Environments (CSE). Based on the High Level Architecture (HLA), this research focuses on implementing simulation technology in a software environment, COSYE, that will be the foundation for building CSE applications. This framework is discussed in the context of tunneling and industrial construction applications, including steel fabrication and pipe-spool manufacture. The framework is demonstrated using the NEST sanitary tunnel project in Edmonton, Canada, in which COSYE was used for scenario-based analysis and planning.

Excavation for construction is implemented in natural geographical terrain using a variety of construction equipment. Therefore, 3D excavation simulation requires integration of geographical and equipment modeling. This paper proposes a technique that integrates geographical and equipment modeling for 3D simulations of construction excavation. The geographical model uses a digital map to show ground surface changes during excavation and the equipment model shows equipment movement and placement. This combination produced a state of the art 3D simulation environment that can be used for machine guidance. An equipment operator can use the 3D excavation simulation to help construction equipment operators with decisions during excavation work and consequently improve productivity.

Visualization of construction process simulation and physical modeling were considered to overcome the limitations of current graphical simulation. The output of discrete-event simulation programs which are the most common mathematical statistical simulation tool for construction processes were analyzed for the visualization of earthmoving process that dealing with objects without fixed. Object-oriented models for equipment, material and work environments were devised to effectively visualize the numerical simulation results of the working time, the queuing time as well as the amount resources etc. The oscillation of the crane's cable and the lifted material that should be considered to rationally modeled and simulated by construction graphical simulation. The derived equation of motion was solved by numerical analysis procedure. Then obtained results was used for physical modeling.

Study from Yogyakarta earthquake reconstruction program, cast-in-place wall using fix-size formwork system (Old-CIP) has offered a good alternative for house construction. A simulation has also confirmed that this system using mortar as the main material can provide cheapest cost and lowest total man power compared to conventional wall construction technique: brick or mortar-block wall. This paper presents the new wall construction technique: full size cast-in-place wall (New-CIP). The detail of how this new technique implemented is described. In addition, considering that material and labor cost in one area is different to others, cost analysis for different resources prices and wages of three cities are taken into a simulation. The analysis is aimed to distinguish the implementation feasibility of New-CIP system compared to the four common wall systems. Finally, its implementation resistance is also discussed.

Because that construction project is usually uncertain and the plan of it changes frequently, it is difficult to make a reliable and feasible plan for it. As the BIM technology is developed, we can simulate the future of the construction project visually and make more reliable plan. However, data production efficiency is not so high, it is used just for animation and presentation usage. Although, a lot of construction simulation systems are developed, it is difficult to measure performance of them. In this study, we defined the construction simulation work process and the scenarios to measure performance of them. The performance measurement method using simulation process scenario can make possible benchmark test of them.

BIM(building information modeling) has been actively applied to construction industries and to maximize its application through the life cycle of structure, various relevant technologies have been proposed. In particular, 4D sequencing management and 5D cost-related management were introduced as an improved version of the design review and interface control by 3D information design. On the other hand, the virtual construction using virtual construction equipment can sophisticatedly handle capacity, dynamic movement, collision boundaries of actual construction machines but it still stays at a low level in a technical sense. In this study, simulation systems based on BIM involving virtual construction equipment have been developed; then it is applied to the actual construction project to evaluate the safety and efficiency of construction equipments. It was confirmed that the simulation systems can be utilized to construct virtual construction site by using an effective 3D library of construction equipment and can plays a key role to secure construction safety and economic feasibility. Specifically, the simulation system are very useful for decision making by construction managers to select the optimum equipment and construction method with a better understanding for safety and cost-saving.

Recently, high-rise building projects have been in the spotlight in South Korea. Curtain wall construction, as one of important operations in the high-rise building projects is composed of various, entangled and complex unit processes that require a systematic planning to prevent unexpected delays. A schedule simulation technique has been used for deriving more efficient planning and accurate performance measurement. However, the simulation technique has difficulty in collecting actual data and in applying data fluctuations during construction. Thus, this paper suggests a concept model of Modular Simulation Model(MSM) that overcomes such limitations of traditional simulation technique based on curtain wall operations.

The current virtual reality(VR) simulation functions in construction project are focused on the construction phase. This study attempts to extend the application of VR functions to the design phase. This study suggests various VR functions such as earthwork simulation by road alignment, alternative route selection simulation, structure type selection simulation and underground structure visualization simulation. These functions can visualize road route and earthwork condition and select an optimal design route by simulating virtual placement of alternative route. This study configures systematic methodology for suggested VR simulation functions and develops VR system by the functions. Finally this study suggests an improved design process of road construction project by using the developed VR functions
