최근 건설 산업은 BIM 도입을 의무화 하는 정책과 클라우딩 시스템, 각종 센서기술, 3D 스캐닝 및 프린팅 기술 등의 ICT기술들과 융합으로 BIM이 더욱 활성화 되고 있다. 하지만 그에 따른 표현 수준이 다양해지면서 하나의 BIM 프로젝트 내에서 계획, 설계, 엔지니어링, 시공 등 각 분야마다 서로 다르게 적용되어 일관성을 갖기 어렵다. 따라서 BIM 적용에 대한 효율성이 떨어지고 발주처의 입장에서 사업초기 단계에 적절한 BIM의 수준을 결정하기 힘들다. 본 연구에서는 이를 해결하기 위해 IT 분야에서 사용하는 SLA을 활용하여 발주단계에서 사업에 적합한 BIM의 목표수준을 정하고 평가할 수 있는 방안을 모색하고자 한다.

The market of building construction has been competitive in Hong Kong, perhaps as anywhere else in the world. The barrier to entry is low because there are relatively low requirements on the three factors of production - technology, manpower and finance. The prevailing building technology is traditional and labour-intensive. There is also not much need of capital because clients' periodic payments have been the main source of project finance. Further, capitalizing on trade sub-contracting, contractors have been able to keep their direct labour-force small and to transfer much of their business risk to the sub-contractors. Based on interviews to solicit the perception of a sample of building contractors on the particular issues of construction finance, we present the findings in this paper and discuss the various implications. We believe that the current practice of construction financing is both the cause and effect of the competition within, and the competitiveness of, the building construction sector in Hong Kong. We conclude that the building construction sector is "locked or stuck" in this "equilibrium" of traditional technology, reliance on clients' finance and exploitation of sub-contracting. In this "equilibrium" state, there is hardly any motivation for contractors to engage themselves in product or process innovation. Consequently, any talk of industry reform or innovation could only remain just that. We believe that this problem is not unique in Hong Kong. The building construction sector in many other developed and developing economies is posed with similar if not the same problems and constraints. We conclude that there has to be some "external forces" to bring this "equilibrium" state to a higher level "equilibrium" one where higher value-added building construction services are supplied and demanded. This is a state where building contractors possessing innovative technology, better financial and manpower resources could thrive to build better buildings with innovative building methods and processes.

국가적으로 전체 터널의 수는 대폭 증가하는 추세이며, 시공 및 유지관리 단계에서 체계적이고 장기적인 계측을 통한 관리가 필수적이다. 그러나 제한적인 계측만을 수행하고 있으며, 계측된 데이터가 체계적으로 관리되지 않아 유지관리 등 시공 이후의 단계에서 기초 정보로 활용하지 못하고 있는 실정이다. 이러한 상태의 주요한 원인 중 한 가지는 기존의 유선 계측기가 터널현장의 복잡하고, 다양한 장비들이 운용되는 상황에서 설치 및 유지관리에 어려움이 있기 때문이다. 또한 고가의 로거의 필요성은 경제성 면에서도 장애가 된다. 따라서 터널의 효율적인 계측 및 관리를 위해서는 경제성이 확보된 무선의 효율적인 계측기의 개발이 선결되어야 하며, 본 연구에서는 지그비(Zigbee) 기술을 활용하여 기존 터널 계측기의 70% 이상을 차지하는 진동현 계측기를 무선화 할 수 있는 모듈의 프로토타입을 개발하였다. 본 고에서는 이와 관련된 다음의 내용을 기술하고자 한다. - 지그비 기술을 활용한 진동현 계측기 무선화 모듈 프로토타입 개발 내용 - 현장 실험 방법 및 결과

Recently, by applying the 4th industrial revolution technologies such as A.I., IoT, and big data to general residential infrastructure, various application services of residential-based are provided to residents through linkage and utilization between technologies. Accordingly, smart housing system is increasing as advanced living spaces that can improve the quality of life and convenience of residents. Such a smart housing is expected to be an item that can create new demands and markets in the construction industry since it provides a new paradigm that combines construction technology and IT by combining IT technology with existing construction industry. Based on this, it is expected that it will be possible to gradually develop large-scale markets such as smart buildings and smart cities. In this paper, therefore, we propose an artificial intelligence multiplex smart housing system as an intelligent platform that can autonomously manage and control the size of places and spaces, used for various purposes based on smart housing technology by using artificial intelligence systems.

Sensors collect information for Internet of Things (IoT)-based services. However, indoor construction sites have a poor communication environment and many interfering elements that make it difficult to collect sensor information. In this study, a network was constructed between a Bluetooth Low Energy (BLE)-based IoT device based on a serverless IoT framework and a router. This experimental environment was applied to large- and small-scale indoor construction sites. Experiments were performed to test the communication performance of BLE-based IoT devices and routers at indoor construction sites. An analysis of the received signal strength indication (RSSI) graph patterns collected from the communication between the BLE-based IoT devices and routers for different testbed site situation revealed areas with good communication performance and poor communication performance due to interfering factors. The results confirmed that structural components of the building as well as the materials, equipment, and temporary facilities used in indoor construction interfere with the communication performance. Construction project managers will require improved technical knowledge of IoT, such as optimizing the router placement and matching communication between the router and workers, to improve the communication performance for large-scale indoor construction.

It is necessary to systematically explore the reform plans of the Software Industrial Promotion Law to systematically a representative high-added value future knowledge-based industry, software industry. The current Software Industrial Promotion Law provides only one provision on software business contract procedures, and the Civil Code, the National Contract law or Subcontract Fairness Law regulate other things, so the features of software industry are not properly reflected. To the contrary, the Information Communication Construction Law or the Construction Basic Law effectively prevent disputes by providing material and detailed provisions. Therefore the current software industry needs to be shifted from promotion to fundamental one. That is, as the software industry takes up a large portion at present, so the law should have basic procedural provisions. Also the National Contract Law governs only the contract procedures of public sector, so there should be business performance procedural provisions to regulate the software business formalities of civil sector. And the National Contract Law controls the sale, construction and service of articles at separate contract procedures, but software business contains construction and service characters simultaneously, so there should be business performance procedures fit for software business. Thus this study presented the legislative need and bill on the performance procedures of software business.

Demand for stone products used as building materials is increasing. The construction industry, the value of the stone industry is sufficient, but the domestic stone industry is very lag regarding IT utilization. However, the overseas stone industry produces high-quality products using IT. In this study, we want to offer an IT application technology priority fit for the stone industries. We identify the current status and production process of the stone industries, then set the priority of various IT, so that obtain competitiveness in the domestic stone industries, and minimize the gap between the overseas stone industries. Therefore, we used AHP method; stone industry production processes were selected as the Enterprise Operation Management, Quarrying, Manufacturing, Construction and Maintenance of first-tier. The second-tier ones are consisted of 30 factors out of IT elements. Focus group interviews were conducted to confirm the validity of each factor. As a result, most important factors of first-tier was selected as the order of Manufacturing, Quarrying, Enterprise Operation Management, and Construction & Maintenance. The top 5 of 30 factors in the second-tier were selected Smart Sensor, Mobile Device, Robot of manufacturing, GIS of quarrying, and SCM of enterprise operation management. And the factor that relatively less important was GPS of construction and maintenance. If properly applied an IT application technology for stone industry, we expect to provide efficient production lines and increase customer satisfaction, which will ultimately expand the promotion for the industry and thus act as positive factor in promoting the stone industry.
