Construction in the UK is the second most dangerous industry in terms of fatal and minor injuries according to the 2014 report of HSE. The use of mobile devices such as iPad, Tablets and Smart phones on the live construction projects is also on the increase in the UK due to the 2016 - Level 2 BIM (Building Information Modelling) implementation target, set by the UK Government. Hence, the use of such devices may become a distraction from work activities on the construction sites and will cause a major risk to the end users. The subject of improving safety of BIM use is widely researched, but there is a gap in knowledge about the actual use of the mobile devices and perception of 'Site BIM', on the construction site activities. The main gap identified in the 'Site BIM' is the health and safety aspect of using such devices on the construction sites. A safer way of working with such devices needs to be identified to avoid any potential site hazards and fatalities before the widespread use of the devices are found on the construction projects. In that context, the paper is aimed to highlight the safety issues that are required to address for the successful implementation of the mobile devices for safer use of the 'Site BIM'. Questionnaire survey was used to collect the site information among construction professionals in the UK. The survey findings suggested that a proactive approach may be helpful to stop potential hazards and risks causing by the use of mobile devices and potential measures need to be identified before any injuries and incidents occur. The paper concludes that training, changing size of mobile devices and ensuring a separate induction training for 'Site BIM' tools will improve the health and safety of the end users of the mobile devices at the live construction sites.

모듈러 건축은 공장 생산 과정을 토해서 품질과 정확도를 향상 시킬 수 있고 같은 유닛을 반복적으로 만들어내기 때문에 대규모 생산과 비용 절감이 가능하다. 특히, 현장 작업과 공장 생산을 동시에 진행 할 수 있기 때문에 공기 단축이 가능하다. 그러나 실제 모듈러 건축 프로젝트 조사 보고서에 따르면 모듈러 건축과 기존 건축의 평균 공사 기간에서는 큰 차이를 보이고 있지 못하다. 이는 모듈러 건축 프로젝트의 실제 시공 시 발생하는 공기 지연 문제 때문이다. 따라서 실제 시공 시 공기 지연 방지를 위한 대안 선택이 필요하며, 특히 대규모 모듈러 건축 프로젝트 현장 시공의 경우 현장에서의 모듈 양중 및 조립 과정이 공장 생산과 동시에 진행되기 때문에 대안 파악이 공장과 현장을 동시에 고려하여 수행되어야 한다. 본 연구에서는 규모에 따른 모듈러 건축의 실제 시공 시 프로세스의 차이를 토대로 IDEF0 모델링을 통하여 대규모 모듈러 건축의 관리 요소를 파악하였고 이를 이용하여 공기 지연을 판단할 수 있는 공장 생산량과 현장 시공량 관리 모델을 개발하였다. 이를 이용하여 대규모 모듈러 건축 실제 시공 시 발생하는 공기 지연 문제를 감소시킬 수 있을 것이다.

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. 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.

Larger and more sophisticated building construction requires more input resources such as worker, materials and devices. Growing resource volume brings risks at a construction site. The industry makes an effort to protect probable incidents at the site by organizing a safety management team. conducting a safety instruction and etc, but losses especially in the construction are higher than other industries. Major reason is that the safety management program is conducted only at the step of construction work and a root cause is not eliminated. Conventionally a concerned party shifts the blame to other parties such as constructor and site workers who are direct participants in the construction site. However, the whole causes of incidents go to the all subject of the construction not only the constructor but the client, designer and others related in the construction, and especially the clients are heavily involved in general concerns of the project. Therefore, this study is defined the role of the clients in nations and domestic condition of construction safety management is investigated. And it is analyzed surveys to prevent incidents at construction sites, and suggested the role of the clients which is classified pre and post construction, and in the middle of construction, and also categorized planning and design & construction schedule especially for the pre-construction level.

There are many accident causes related to even an accident. As well four(4) stepped causes of one accident at construction sites are analyzed in the study. First, eleven(11) cause factors are set up at each step such as policy level, management, indirect, direct level which are discussed and determined by field experts with 15year experience or more. Therefore, one direct cause occurred in construction site can be connected to the previous cause than in direct and management, and policy problem of previous management. These questionnaires results are analyzed with three different methods such as weighing level by Delphi technique, correlation analysis, critical pass method. Three different methods show their characteristic to see which subcontract work is more dangerous or not. Subcontract or at a construction site can be use the above three different cases as they need at their site in order to make more effective countermeasures.

Determining the layout of temporary facilities that support construction activities at a site is an important planning activity, as layout can significantly affect cost, quality of work, safety, and other aspects of the project. The construction site layout problem involves difficult combinatorial optimization. Recently, various artificial intelligence(AI)-based algorithms have been applied to solving many complex optimization problems, including neural networks(NN), genetic algorithms(GA), and swarm intelligence(SI) which relates to the collective behavior of social systems such as honey bees and birds. This study proposes a site facility layout optimization algorithm based on self-organizing maps(SOM). Computational experiments are carried out to justify the efficiency of the proposed method and compare it with particle swarm optimization(PSO). The results show that the proposed algorithm can be efficiently employed to solve the problem of site layout.
