With the increased dependence on subcontracting in the construction industry, the operational relationship between main contractors and subcontractor plays an imperative role in successful project delivery. Consequently, improving this relationship increases the probability of project success and enhancing project performance. A wide range of research has confirmed that partnering improves the main contractor-subcontractor relationship. Though the positive impact of partnering on project performance is supported by a plethora of evidence, the guiding theory on practical partnering process steps is limited. The study aimed at improving subcontracting in the construction industry through a partnering process relevant to Zambia guided by factors obtained from industry expects. Questionnaire surveys and Semi-structured interview were adopted to investigate the perception of construction industry professionals and academics towards the main contractor-subcontractor relationship along with improvement factors. The findings showed that the relationship between main contractors and subcontractors on most projects in Zambia is unsatisfactory therefore justifying attention. Top factors that can enhance the main contractor-subcontractor relationship were identified. From the factors deduced and guidelines on partnering best practices, a project partnering model was developed.

A contractor or a main contractor is a company with full capacity to construct all project's works for the owner. A subcontractor is an organization that works with the main contractor to execute and complete work packages for the project. Selecting an effective subcontractor will help the efficiency and success of any projects in the construction industry. Therefore, this study identified subcontractor evaluation factors in Vietnam by collecting questionnaire survey data from engineers and staffs in the construction industry project environment. An exploratory factor analysis (EFA) was then performed to identify the critical factors when evaluating and selecting the subcontractor in construction projects. Moreover, when considering the impact level in terms of the average value, the research results showed that the most critical concern was the subcontractor's reputation. Furthermore, the top five factors affecting the sub-contractor evaluation and selection are (i) reputation, (ii) price, (iii) construction techniques, (iv) ability to implement projects according to commitments, and (v) subcontractor competence (the team of workers, technician staff, engineers with full capacity according to regulations). These research results provide an overall perspective that will help main contractors develop suitable subcontractors' evaluation and selection factors in their projects in the construction industry.

건설시장의 구조를 보면 발주자로부터를 낙찰 받은 하도급자는 이를 3차 하도까지 주고 있다. 이렇듯 원도급자가에게 하도를 줌으로써 결과물 생성을 하도급자가 맡게 된다. 현장 생산성에 직접 관계를 맺고 있는 하도급에 대한 연구가 부족한 것으로 보인다. 건설업의 특성상 한 프로젝트에 각 분야의 하도급업자가 참가한다. 프로젝트에 참여하는 하도급자의 품질 및 작업을 향상 시킨다면 작게는 한 업체의 생산성이 향상되는 것이지만, 이것이 점차 넓어지면서 프로젝트 전체의 생산성을 향상 시킬수 있는 것이다. 이런 점에서 하도급 생산성에 대한 이해를 하고 분석함으로써 하도급생산성 향상 방안을 제시하고자 한다.

The DQMS (Defence Quality Management System) is a certification system that manages participating companies to improve the quality of munitions. Since Korean Defense Specification (KDS) for DQMS certification that was established by adding military requirements based on the ISO quality standard, many companies complain that they should pay too much effort into the preparation process. However, it is hard to find helpful information on the preparation process because we have been only interested in the effect of DQMS acquisition. The purpose of this paper is to provide helpful information to companies preparing for DQMS certification. We surveyed the degree of difficulty and importance of the DQMS requirements from the companies with certification experience, and performed IDA (Importance-Difficulty analysis) by dividing the companies into the main contractor and the subcontractor. The result of IDA shows that there is a different recognition to the DQMS certification between main-contracting and sub-contracting companies. Subcontractor has more difficulties than main contractor in preparing the DQMS certification. In addition, we are able to identify the difficult and important requirements in the preparation process to the DQMS certification. Both main contractor and subcontractor have difficulty to the requirements related to configuration or validation such as 'customer controls configuration', 'configuration review shall be implemented' and 'design and development validation documentation.' The requirements related to customers are important to main contractor but the subcontractor regards difficult requirements as important ones. The result of this paper would be helpful to both the company preparing for DQMS and the munitions quality assurance agency.

Accident prevention plan it a construction site should be analyzed and made with risk evaluation and management, from recent year, in Korea. Accidents occurred in construction site are related to all parties such as owner, main and subcontractor, labour. But analyzing some relationship between main and subcontractor is very important to estimate what risk between then are existed in a site. There are some different aspects concerning with risk management between them. Everywork has its own risk in there, This is the reason why everywork which are made by subcontractor himself should be evaluated for risk level. And main contractor should provide for subcontractor to prevent each risk at the work, all the time.

Most of the construction works in domestic are not direct undertaking work, but by a contract method including subcontracting. Therefore, a general contractor for each project jointly carry out construction work with a specialty contractor for each engineering type. However, in terms of contract, this method is not a joint venture contract, but a subcontract. Accordingly, this system can cause various problems between the prime contractor and the subcontractor. Therefore, this study aims to extract and present the actual obstacle factors in terms of specialty contract company performing specialty construction work for construction project. The presented contents are expected to present the standard for the cooperation system that the prime contractor and the subcontractor can win-win.

The general contractor business in South Korea settled in the railway construction during the Daehan Empire, but depending on the construction intention and circumstances of the railroad, relationship among employer-contractor-subcontractor and their roles under the system of the construction process had changed. At the time of laying the Gyeongin and Gyeongbu-rail, the Empire, which had no capital and technology, passed all the power and responsibility of the rail laying to the contractor, who was involved in most of the process. After this, the empire tried to lay Gyeongui-railroad without the help of other countries. Japan prepared for the Russo-Japanese War and decided to construct the railway rapidly, and completed the railway in parallel with direct management work and contract work. From that time on, the general contractor would only do the work. During the construction of railroad in Daehan empire, the general contract business system was established. The ambiguous process was sorted out and divided. At this time, subjects in charge of design and construction has been divided. The internal organization of the project owner and the contractor were organaized and specialized.

It compared subcontractor with contractor that are wages, the labor hour and labor condition of the work environment back are inferior relative. The subcontractor which basically the contract workers evade the dangerous process or the difficult work, the dirty work back what is called 3D the case which does to keep a business is many. so With life it will be threatened consequent health directly. The possibility where the subcontractor will be exposed to danger work came to be high. Together the reason of subcontract at managing the big business the case which becomes accomplished in objective, about lower the immediacy safety&health problem, subcontractor assigned workers is the actual condition only it could not be deteriorated more in public finance of the supply and enterprise and technical ability insufficiency. Consequently it prevents the subcontract which danger work is insensitive from this research and immediacy of the subcontract workers who is weak hygiene circumstance complement the plan it will be able to secure the immediacy safety&health subcontract workers, substantially to prepare in the hazard subcontract proprietor.
