The comprehensive Topic of Total Quality Management (TQM) has been put forward since the 6^th decade in industrial countries. The serious attention to it in developing countries goes back to recent years. Unfortunately serious attention is not paid to quality issues in building industry. Therefore, the construction of buildings is highly vulnerable against natural events while having low effective lifetime. Wide-range destruction of the residential buildings in the earthquake of Bam ( in IRAN ) is a clear proof for this claim. In this paper we tried to present the corresponding effects between quality issues and other aspects of a building project (such as costs) and proposed general solutions to improve quality indices in construction industry.

Construction designs are often produced with insufficient considerations on the constructability aspects. Poor constructability has resulted in delay, cost increase, disputes, safety hazards and inconvenience to the public. Increasingly, there has been a call for more systematic input of construction knowledge in the planning and design processes of modern day's infrastructure development. In some countries, notably the US, the practice of constructability reviews is on the rise, with concomitant benefits. It is advocated that construction plans and designs be subject to constructability reviews as early as possible. It should be made part of the project management strategy driven by the client. This paper outlines the constructability review process and benefits, whilst drawing lessons from a number of case studies.

Before a contractor embarks on exporting its services, it needs to know if it is likely to succeed. This research developed two prediction models to help contractors in Singapore predict the number of projects (Y1) and the contract values (Y2) that they are likely to secure from overseas. Detailed characteristics of 60 contractors who export their services (exporters) were obtained from the database of registered contractors in Singapore. Multiple linear regression models were developed and tests showed that Y1 is a robust model. A contractor's chance of winning more overseas projects may be predicted by the number of projects it acted as a subcontractor; the variety of projects it undertakes; the total contract value in the domestic market; and the number of countries it exported its services to. It is recommended that contractors who are planning to export their services be flexible instead of adopt a focused policy of undertaking only one or two project types in a few selected countries.

Recently, the scale of construction project is getting bigger compared to previous projects. Therefore, the job stress of the field manager responsible for the construction project is getting more and more intense. Therefore, construction companies should establish a job stress management plan for stable human resource management of the field managers. From this perspective, in this study was developed a job stress measurement system in connection with MBTI personality types. The developed system allows the job stress of the field manager to be judged on a scale from 1 to 9 points. Accordingly, it is expected that construction companies will contribute to the effective management of field managers in the future.

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.

In order to maintain the existence of a university in the era of infinite competition, it is actively promoting the establishment of a school dormitory, one of the welfare facilities, as a way to attract students who want to enter the university. In the past, university dormitories were built by the university and managed and operated on themselves, but recently, due to the poor financial situation of the university, university dormitories promoted BTL method that private construction company built dormitories and rented them for a certain period of time to manage and operate. J University has dormitories managed and operated by itself and dormitories managed and operated by entrusting the private sector. User satisfaction surveys are conducted on two dormitory facilities with different management and operation organizations, and the contents of the survey are compared and analyzed. This study is expected to be used as basic data when planning a dormitory remodeling project or a new dormitory establishment project in the future.

KPI, an indicator that measures the performance of factors that contribute to achieving strategies of individuals or organizations, is used a lot to analyze the performance of construction work. Construction work consists of individual construction types with different characteristics such as progress method, scale, and input resources, but currently, KPIs for performance analysis of individual construction types are lacking. Therefore, this study aims to obtain and analyze data for establishing construction performance analysis KPIs during construction work to prepare the basis for the creation of future construction KPIs. Preliminary KPIs for earthwork performance analysis selected through this study are expected to be the basis for deriving preliminary KPIs for other individual construction types.

Precise construction cost estimation is paramount to determining the total construction expense of a project prior to the initiation of the construction phase. Despite this, manual quantification and cost estimation methods, which continue to be widely used, may result in imprecise estimation and subsequent financial loss. Given the fast-paced and efficiency-demanding nature of the construction industry, trustworthy quantity and cost estimation is essential. To mitigate these obstacles, this research is focused on establishing an automated quantity estimation algorithm, particularly designed for the main rebar of beams which are recognized for their complicated reinforcement configurations. The exact quantity derived from the proposed algorithm is compared to the manually approximated quantity, reflecting a variance of 10.27%. As a result, significant errors and impending financial loss can be averted. The implementation of the findings from this research holds the potential to significantly assist construction firms in quickly and accurately estimating rebar quantities while adhering strictly to applicable specifications and regulatory requirements.

For the sustainable development of the domestic construction project management field, each CM company should try to diversify in terms of service contract types and scope of work while having internationally competitive technical and service capabilities as follows. First, from the initiation of the service to the completion, the CMr should be able to establish and execute a plan to create specific outcomes. Second, CMr must have the capability to produce weekly or monthly cost, schedule, risk, and scope management reports. In addition, it should be possible to apply the cost plus sliding fee method or to systematically and continuously accumulate and process data generated during the construction process.

A subcontract work order is the basis of the construction process and consists of the root and trunk of the construction industry. The construction process through a subcontract work order is an important element of project success, and it is the basic unit of creating profit in the construction industry. Therefore, correct analysis and forecasting of subcontract work orders allow correct estimation of construction cost and profit which is the foundation of corporate decision making. This study has started to provide predictions of subcontractor's bidding-ratio for decision-making. Since the actual project data has been used in this study, the contribution level of the model is highly expected in actual field. The statistical confidential level of adjusted decision coefficient is concluded low because of limited sample numbers. However, its accuracy and confidence level can be increased through increasing sample numbers, considering more variables, and studying of reducing error.
