The performance of projects has always been an area of interest in the construction industry. Roles of all construction supply chain partners are necessary; however the role of a contractor firm in the construction project is pivotal. So, this research intended to explore a Construction Firm's performance criteria which could measure the level of performance of that firm in an ongoing project. Data was collected from construction professionals working in three principal project participant organizations, namely Owner, Consultant and Contractor. A total of 113 nos. of performance measuring items were sorted from literature review and used to collect data. Statistical tools processed by SPSS program was employed to analyze the data. Out of total 113 items, only 65 nos. of variables were found to be acceptable to every population group of this study. Factor analysis revealed 12 key performance predicting factors (KPPF) with 53 predictive indicators. 12 KPPFS with index weight are: work progress and smoothening (9.3%), change order management and work accuracy (9.1%), business relationship building (8.1%), adequacy of construction work procedure (8.6%), quality performance (8.0%), health and site safety adequacy (8.8%), Innovative contractor (8.0%), adequacy of construction site information (6.8%), compliance with contract plan/specification requirements (8.9%), creditworthiness and financial capability (8.3%), intra-agency relationship and responsiveness (7.0%) and resource management (9.2%). These results could be useful to project management body to evaluate performance of its contractor firm on site as well as the contractor itself to assess own performance and its subcontractors on-site.

Lack of client involvement in construction of public projects has been identified as the main cause of many operational problems. Clients need to perform their roles and responsibilities effectively and efficiently at the right time and through the use of correct methods in order to have the optimum involvement required during all the construction project phases, namely, the planning, design, construction, handover, and operation and maintenance phase. This paper investigates the influence of clients' individual factors on their involvement in construction project delivery. A questionnaire survey was distributed to various government agencies of the Kingdom of Saudi Arabia (KSA). Explanatory Factory Analysis was performed to group nineteen individual factors. The factor analysis result suggests that the individual factors that can involve clients' involvement in construction projects can be grouped into five, which are: adequacy of knowledge and experience for decision making in the early stage of design; ability to communicate clearly; job satisfaction; personal skills; and expertise in design and construction.

A construction site survey is carried out for the Construction Standard Unit Price(CSUP) in order to establish a standard for the appropriate estimated price. This paper proposed the revised plan by surveying the 56 sites under construction from March to October 2022 for interior finishing work and Carpentry work. It is expected that the revision of the CSUP for interior finishing work and Carpentry work will more accurately reflect the actual construction situation and contribute to improving the adequacy of the CSUP.

It has regarded an attempt to design and construct more safe structures as challenges such as fate. In order to operate public facilities safely, It can be taken how to improve the resistance to applied load by increasing the cross-section of structural members or by installing reinforcement. But inevitably such a way is accompanied by an increase of construction cost or maintenance cost. To make a cost-effective construction, Reliability-based decision analysis which can judge the adequacy of investment is suggested using statistical data of the load, resistance and the maintenance cost.

Korean government has developed and implemented a five-year master plan in order to enhance construction technology competitiveness and its level of development. However, without detailed assessment of past plans it is not likely to retain feasibility and sustainability of a new five-year plan, This study analyses adequacy of the 4th five-year master plan in terms of evaluation strategies such as indicators, methods, targeted performance through benchmarking various construction policies utilized by developed countries. In addition, this manuscript provides the basis structure and critical factors for establishing future construction policies or plans.

This study was conducted to determine the elements that are required and that need improvement in the contents of dietary life education and the educational environment by analyzing the importance-satisfaction of a dietary life education program for dietary life education trainees. The results of the rank test for the satisfactory elements of dietary life education were in the order of competence of instructors, educational contents, time of education, educational environment and affordability of tuition. The importance-satisfaction analysis of the contents and construction of the dietary life education program showed that "suitable contents for the theme of the class", "contents and construction of practice class", "diversity of practice menu" and "diversity of educational contents" had high importance and satisfaction scores and therefore, could be maintained at their current levels. Meanwhile, "adequacy of class time" and "contents and construction of theory class" showed low importance and satisfaction scores, requiring a little effort. Whereas, "time and construction of group practice", "structure of textbook for class" and "duration of course and number of classes" showed relatively low satisfaction compared to importance, requiring major efforts for improvement. Similarly, analysis of the lecture element from dietary life education showed that "professional lecture by instructors", "lectures suitable for themes" and "lecture applicable in real life" had relatively low satisfaction compared to importance, requiring major efforts for improvement. In addition, analysis of the educational environment from dietary life education showed that "adequacy of lecture room space", "cooking equipment", "diversity of cooking utensils" and "sanitary condition of cooking utensils" also require major efforts for improvement. Therefore, dietary life education should not be executed with a simple delivery of knowledge but with both theory and practice classes to increase its application in real life, and active and specific efforts are required to nurture professional instructors and establish educational strategies.

건설산업에서 안전사고를 줄이기 위한 노력을 다양한 방법으로 꾸준히 하고 있지만 줄지 않고 있다. 따라서 설계단계에 설계의 안전성 검토를 도입하여 안전사고발생의 근본적 원인을 제거하고자 2016년부터 설계 안전성 검토를 도입하여 시행하고 있다. 본 연구에서 설계 안전성 검토 시행의 적정성과 문제점을 도출하여 제도가 올바르게 정착하여 안전사고를 줄이는데 기여하고자 하였다. 따라서 관련 기술자들에게 설문조사를 하고 설계 안전성 검토 보고서를 분석한 결과 관련 기술자들의 설계의 안전성 검토에 대한 인식률이 낮고, 설계의 안전성 검토에서 도출된 위험요인도 설계 사항이 아닌 항목이 다수인 것으로 나타났다. 따라서 실질적인 설계단계 설계상 위험요인을 줄이는 노력을 하여 안전사고 감소에 좀 더 기여할 수 있도록 하여야 할 것이다.
