For decades, the productivity issue has been a primary concern for the all stake-holders who participate in domestic construction industry. Especially, between a whole life cycle of building, the construction phase's productivity problem makes or break the entire project. In this respect, the general construction company, who accept the order and construct the building(so called General Contractor), should consider various strategies, such as schedule management, cost management, quality management, inner-crew management, etc., for the productivity improvement., and almost of these management methods have been studied for a long time. But, the researches and studies about the specialty contractor, who construct the building directly in construction site were not sufficiently complete yet. This research begins as an idea which tries to apply the BIM(Building Information Modeling) into the tasks of Specialty contractors for their productivity improvement. And for the effective application of construction BIM to specialty contractors, establish of the BIM project execution plan for them, not the fragmentary adoption of BIM. Therefore, in this paper, we develop the BIM project execution plan for the reinforced concrete companies who conduct the framework construction which located on CP(Critical Path) Especially, we model the "Construction BIM Use List for the RC Work", "BIM Application Master Process" and "BIM Application Detailed Process", and general contractor who use these BIM uses list and process models can manage various specialty contractors about schedule, cost, earned value, quality, safety and environment management systematically.

Despite the acknowledged benefits by incorporating daylighting in the lighting system of office buildings to enhance energy efficiency and ensure occupants' well-being, a significant gap in understanding the integration of daylighting control system (DCS) with Building Information Modeling (BIM) exists, which can lead to improved energy efficiency and enhanced building design, specifically regarding the impact of daylight on occupant comfort. Previous studies have highlighted the potential of BIM to revolutionize both architectural design and building performance. However, an untapped potential of BIM in facilitating daylighting control in office areas is yet to be explored. The significance of this study lies in prioritizing occupants' well-being and enhancing building performance. This research identifies the feasibility of BIM-enabled DCS through a literature review from three perspectives: BIM-enabled DCS and daylight strategies, BIM-assisted façade system improvement, and user-centric daylight utilization within BIM platforms. As for results, a sensor network diagram illustrating network structure, data flow, and connections between devices of BIM enabled daylight control system for office buildings are established. Additionally, a BIM assisted daylight control strategy diagram is presented to outline user-centric control facilitated by BIM platform. In terms of contribution to the body of knowledge, this research will provide a comprehensive synthesis of existing literature in this domain. Additionally, this research could provide architects, DCS designers, and sustainable building professionals with potential advancements and inspirations to promote energy-efficient and user-centric building design in the future.

Various types of building information should be linked to 3D model objects for their effective use by stakeholders. Because Building Information Modeling (BIM) based on 3D is used by different stakeholders, the created BIM need standard guidelines for each purpose, as, for example, for quantity take-off. Thus, this study was conducted to propose guidelines for BIM modeling for quantity take-off in the framework, especially, in the concrete and form. The proposed guidelines adopted each element of the BIM model based on an analysis of the problem of the general BIM model. Moreover, the usability and accuracy of the reinforced structure modeling guidelines were verified by comparing the quantity of the commercial estimation software and the modeling quantity using the proposed modeling guidelines.

Visualized information platforms through building information modeling (BIM) such as virtual reality (VR) and augmented reality (AR) improves the efficiency of architectural information exchange. Despite that, less effort has been directed to evaluate the effectiveness of different BIM visualization platforms for architectural design review. This study fills these gaps and compares three BIM visualization tools for reviewing diverse architectural review factors and technology acceptance degree. Three main BIM visualization tools, which are desktop-based, virtual reality-based and augmented reality-based, were employed and different architectural review factors and user's technology acceptance degree was measured. As a result, VR and AR environment showed better visual presentation than desktop environment during design review. In terms of the technology acceptance level, VR and AR environments have received higher ratings compared to desktop environments. The detailed findings provide guidelines for participants and researchers involved in design review process to selectively adopt VR and AR system to various architectural design review components.

Lately, Building Information Modeling (BIM) emerges as the most promising technology, now is expected to bring a great deal of improvement of productivity in every aspect of the construction industry. One of the BIM based scheduling is to use BIM model as a base for applying to schedule analysis and simulation tools. This type of tools may incorporate a various types of information such as the building model, construction method information, resource information, productivity information, rules and constraints to optimize activity sequencing. This paper proposes a framework of BIM based simulating system which can be used to optimize construction processes, especially for the floor construction cycle. For the purpose, all of the necessary components of the system will be defined and represented, and next an algorithm will be introduced to demonstrate the principle of simulating operation. The benefits of this technique are basically two : to test and optimize construction methods in respect of the construction duration and to reduce the floor construction cycle.

Building Information Modeling, which was applied mainly in the construction sector, is expanding to the road sector, and the government recently recommends preparing individual application guidelines considering the characteristics of detailed fields such as railways, ports, and complexes through BIM implementation guidelines. Compared to general construction projects, a lot of the works such as signals, electricity, and power, and the railway BIM 2030 roadmap has been presented to apply BIM to railway construction projects that require business consultation and work environment review with various local governments, and pilot projects are in operation. Unlike a general building, in which the construction begins after the detailed design is completed, in the railway project, the detailed design of other works proceeds along with the roadbed construction. Because construction and design work together, railways need to coordinate detailed engineering interfaces such as trajectories, signals, and power, and the application of BIM in design interface coordination has the advantage of maximizing the effectiveness of pre-review. Overseas railway construction projects actively used BIM to adjust design interfaces and had a collaboration process to modify BIM models and create construction details from the revised models through regular meetings with suppliers. Therefore, this study aims to derive the factors necessary for establishing a BIM collaboration environment based on a survey of practitioners as a preliminary step for establishing the BIM collaboration process of the railway construction project.

This paper recognized a need in the architecture, engineering, and construction industry for new programs and methods of producing reliable energy simulations using BIM (Building Information Modeling) technology. Current methods and programs for running energy simulations are not very timely, difficult to understand, and lack high interoperability between the BIM software and energy simulation software. It is necessary to improve on these drawbacks as design decision are often made without the aid of energy modeling leading to the design and construction of non-optimized buildings with respect to energy efficiency. The goal of this research project is to develop a new methodology to produce energy estimates from a BIM model in a more timely fashion and to improve interoperability between the simulation engine and BIM software. In the proposed methodology, the extracted information from a BIM model is compiled into an INP file and run in a popular energy simulation program, DOE-2, on an hourly basis for a desired time period. Case study showed that the application of this methodology could be used to expediently provide energy simulations while at the same time reproducing the BIM in a more readably three dimensional modeling program. With the aid of an easy to run and easily understood energy simulation methodology, designers will be able to make more energy conscious decisions during the design phase and as changes in design requirements arise.
