As contemporary building construction type is getting higher and deeper,construction equipment usage is getting more, and related fatal accidents are on an increasing trend. In these days, due to the deteriorating construction business circumstance, job finding problem of equipment operator, and dumping contract, equipment lease suppliers are putin jeopardy. In high-rise building construction, especially tower crane, mobile elevated work platform and other High place operation cars among construction equipment cause many critical accidents because of drop supply of construction biding bringing out dumping contract could cause unsafe and poor construction management. Because of this, a method was drawn which could grasp the present state of construction equipment management and manage safety of the equipment more easily for accident prevention by choosing 2 kinds of Construction equipment which cause safety accident frequently among the equipment mainly used in construction site. This study suggested a method about construction equipment safety management using "smart phone" base which could be used in safety management for construction equipment by whomever in construction site. After attachment of QR code included safety checklist, It became possible that site managers could check more efficiently by scanning with their smart phone when they inspect equipment. Moreover, by the construction interested who didn't know what and how they have to inspect could point out unsafe condition in the early stage of equipment entering or take unsafe one out of the site by using new smart phone safety checking system is installed, it became possible that critical accident caused by construction equipment was prevented in advance.

As construction works have become larger and more complex, improving productivity by introducing Information Technology (IT) is pursued and more effective construction management is needed in construction industry. In this circumstance, many different kinds of project management system is being introduced, and various IT technologies are applied such as Personal Digital Assistant (PDA), Bar Code, Radio Frequency Identification (RFID), Web Camera, and so on. However, these kinds of technologies might cause re-processing of information and ineffectiveness of project because of lack of real time information processing technology or separation between construction sites and management offices. Meanwhile, these technologies rather decrease the construction productivity except for the data saving and database function. Therefore, this research aims to develop Application that can be applied efficiently for construction material management, by understanding problems of former management system with questionnaires and extracting functions with analysis of requirements. In virtue of the construction material management Application which will be developed in this study, it will be possible to input information automatically, to process and check material information in real time, and to identify the location of necessary material. Then, the problem of separation between construction sites and management offices are solved, and as a result, more efficient management of materials in construction sites will become possible. At the same time, this study will investigate the possibility and applicability of new IT device, Smart Phone to construction sites.

Because irregular shaped buildings are designed with various three-dimensional curves, the difficulty of design and construction is very high, and more construction drawings are needed to reduce construction errors. General 2D drawings may have limitations in conveying the information necessary for construction. By utilizing BIM, it is possible to three-dimensionally design parts that are not expressed on 2D drawings and additional structurall components required for the construction of the curved exterior finishing materials. This study examines the necessity of BIM at the construction stage, its performance through it, and how it can be linked to smart construction technology through construction BIM being applied to the new construction site of Sejong-Pocheon Line Cheoin Rest Area.

The major objective of this research is to evaluate performance of improved intersections for response time to emergency vehicle preemption. Smart technologies have been introduced to civil infrastructure systems for resilient communities. The technologies need to evaluate their effectiveness and feasibility to confirm their introduction. This research focuses on the performance of emergency vehicle preemption, represented by response time, when smart intersections are introduced in a community. The response time is determined by not only intersections but also a number of factors such as traffic, distance, road conditions, and incident types. However, the evaluation of emergency response has often ignored factors related to emergency vehicle routes. In this respect, this research synthetically analyzes geospatial and incident data using each route of emergency vehicle and conducts before-and-after evaluations. The changes in performance are analyzed by the impact of smart intersections on response time through Bayesian regression models. The result provides measures of the project's performance. This study will contribute to the body of knowledge on modeling the impacts of technology application and integrating heterogeneous data sets. It will provide a way to confirm and prove the effectiveness of introducing smart technologies to our communities.

본 연구는 국내 최초 스마트시티로 지정된 건설 현장에 적용된 스마트건설장비의 효과를 분석하여 향후 스마트건설장비의 발전 및 활성화 방안을 도출하는데 목적이 있다. 이를 위해 토목공사 현장에 적용되는 대표적 스마트건설장비인 머신가이던스(Machine Guidance; MG)기술에 의한 안전시스템과 시공시스템의 실제적 활용 효과와 문제점을 분석한 후에 개선방안을 제시하였다. MG안전시스템과 MG시공시스템 모두 결과적으로 시공성 개선에 충분히 활용성이 있음을 파악하였고, MG시스템에 의한 작업결과의 승인문제와 잦은 현장 장비교체에 의한 시스템 변경문제, 고령의 현장 근로자의 사용성 개선문제 등이 속히 해소해야 할 과제로 분석되었으며, 연구에서는 이러한 문제에 대해 현장에서 해결한 일부 방안을 제시하였다. 연구에서 제시한 활용효과와 문제점 등은 머신가이던스기술을 현장에 상당기간 실제로 적용한 후에 직접 활용한 근로자와 관리자 등을 통하여 분석하였으므로, 장비자동화를 위한 실증적 분석 자료가 많지 않은 점에서 향후 유사 현장에 적용하기 위한 선행자료로 활용성을 갖을 수 있다.

인터넷 상거래가 증가함에 따라 전세계적으로 대형 물류 건물의 건설이 증가하고 있다. 이들 건축물은 대부분 장경간중재하의 특성을 가지고 있으며 빠른 시공을 위해 핀조인트 구조인 PC 공법을 적용한다. 그러나 핀조인트 구조는 시공 안전성 및 구조적 안정성으로 인해 PC 부재의 설치에 많은 제약이 있어 시간과 비용이 많이 소요된다. 이러한 제약과 문제점을 해결하기 위해 PC 부재 사이의 철골 조인트로 연결된 구조 프레임인 SMART frame이 개발되었다. SMART frame에 대한 많은 연구가 진행되었으나 공기 측면에 대한 영향은 분석되지 않았다. 본 연구의 목적은 장경간 중재하 물류창고시설에 대한 SMART frame의 공기단축 효과를 분석하는 것이다. 본 연구를 위해 기존 PC 공법에 의해 건설된 사례현장을 선정하여 SMART frame 설치 시뮬레이션과 시간 단축을 비교하였다. 그 결과, 기존 PC설치공기의 약48%의 수준으로 약 4개월이 단축 되었다. 추후 대형물류센터 프로젝트 진행 시 SMART frame을 적용한다면 기존 PC공법 대비 획기적인 공기단축의 효과를 가질 것으로 기대된다.

The structural work is the main process of building construction which influence on the time, cost, safety and quality. The form work is one of the main process which has from 20 to 30 percentage of structural work. Especially the form work for beams is complex and need more manpower compared with form work for column or slab. When the existing forms such as plywood form, steel framed wooden form and aluminum form, is used for form work of beam, it would result in the cost overrun caused by needs of lots of manpower and resources. Therefore, the aim of this study is analysis of the requirement for development of SMART beam form. The result of this study shall be used for the development of SMART form work system.
