Accurate construction progress measurement is an important issue for successful project delivery. This paper presents a method that keeps track of the progress measurement involved in construction operations and facilities visualization of the data using BIM and IOT. To verify the method, a residential house project was used for the case study. Test case verifies the usability and validity of the method implemented in the system.

The important consideration in laboratory designing and construction of the artificial pollution testing facilities including 300kV, 1800kVA AC test system, which enable to test and evaluate the UHV dielectric performance of power insulators up to transmission class, has been dealt in this paper. To evaluate the performance characteristics against contamination for various power installation, especially for the insulators and kinds of bushings, brief investigation and an analysis of test objects and related international codes and standards have been conducted. With the special consideration concerning other matters in designing of these testing facilities have been described with the fixed ratings and references.

This paper aims to identify patterns in users' requests for facility management (FM) services in higher education facilities. We analyzed data collected from 309 service request forms, made available via a department office and an enterprise resource planning system, at a private university in Seoul between May 2009 and February 2015. We found that the number of user requests were the highest in September and October. Requests for electronic and communication (E/C) services outnumbered those for architectural services and mechanical and plumbing (M/P) services. Repair requests for doors and windows were the most common under architectural services; repairs for air-conditioners and radiators were the most commonly under M/P services; and installation of electrical outlets, telephone wires, and internet services were the most sought-after E/C services. Maintenance requests were received every three months, while repair requests were received every six or seven months.

Korea Gas Corporation(KOGAS) have constructed a gas flowmeters' calibration facilities at Jungdong Bucheon. The facilities consisting of 6 reference turbine meters can perform calibrations of large capacity natural gas flowmeters up to $9,600 m^3/h$ at 95 kPa. This large capacity and high pressure natural gas facilities is traceable to the national standard of gas flow rate (KRISS). In this article the motive of construction and description of design are summarized.

This study analyzes remaining repair rate and applied repair rate with the presentation of profit model for the purpose of pursuing maximization of added value through remodeling of apartment house. Objects of remodeling and item applying the whole replacement of functionality evaluation items include exterior of building (3 items maintaining the current conditions, 8 items requiring the whole replacement), water supply/sanitary/gas/ventilation facilities (6 items maintaining the current conditions, 6 items requiring the whole replacement, electric/fire fighting/elevator facilities (8 items maintaining the current conditions, 20 items requiring the whole replacement) and heating/water heater facilities (2 items requiring the whole replacement).

Recently, South Korea is reaching aged society through ageing society. Accordingly, facility related to aged is increased consistently because of effort to improve the welfare of the elderly through elderly long term care insurance in 2008. however, the number of fires in the elderly facilities is increasing rapidly too. It is becoming bigger and higher and the characteristics of person who is unable to afford are mostly having difficult evacuation. so fire safety guildelines are urgently needed but korea research is insufficient. In this study, we propose a fire scenario through investigation of fire causes for fire safety guideline development of elderly facility, and describe to the fire safety countermeasure.

Recently, the premature corrosion for reinforced concrete structure exposed to chloride bring about a serious problem in concrete structures. Specially, the concrete structures of sea coast are exposed much to chloride which make rapid corrosion. Thus, construction activities and maintenances for marine facilities are more demanded than those for land structures. The results of this study have been analysed to identify the extent of chloride content and incidence of carbonation for construction age. After measuring chloride content in concrete, it was conclued that about 90% of all tests on concrete samples exceed the acceptable maximum limit to risk of chloride-induced carbonation. The carbonation rate coffnient by age of train structures in the east eatimated 6. 55, 4.76 grater than 3. 727. In the basis of this result, it is necessary to maintenance for the important train facilities with the regular tests of chloride and carbonation.

Recently the renewable energy has been used widely and the importance of renewable sources is bigger than before. So the government enforced a law to the public buildings to install the renewable energy facilities. The capacity of facilities is 5% of total construction cost until April 13, 2011. Since then, the government changed the law from 5% of total construction cost to 10% of predicted energy usage because of the practical use of the renewable energy facilities. So, in this study, the comparative analysis is conducted according to the law to the building installed PV system through the EnergyPlus simulation.

In this research, we determine the proper number of entrances in the evacuation facilities for civil and military personnel. The current standards on the emergency evacuation facility only sets the number of possible evacuees and the according architectural floor area since the evacuation have been completed. However, other than static standards such as the floor area, there is needs to consider the dynamic standards along with allowable evacuation time such as the number of entrance, staircases and so on. Therefore, we need to consider the number of entrances and their location in order to account for the allowed evacuation time of particular number of people in a set area. The outcome could be contributed to the standards which should contain the dynamic conditions associated with evacuation.

Interior space of large scale composition facilities influences in walk population of distance according to trade and space rescue and walk population of distance is armed business activity. First, chose representative COEX mall of domestic representative multiplex utilization facilities on greate upper limbs for progress of research. Because executing space analysis of COEX mall interior, can analyzed the walk amount and location and also confirm result that floating population according to accessibility increases. Produced time, day of the week, the passageway passing amount through CCTV on actuality COEX mol interior to compare this. Was proved that it is quantity in the passageway passing amount and analysis incidental of the passing amount that get executing space difference.
