This study is to suggest strategies of specialty contractors that provide labors oriented engineering service by interaction analysis between construction business indicators and business performance indicators. For specialty contractors that mainly provides labor oriented engineering service, the amount of construction orders imposes lasting impact to the turnover ratio of current assets supposedly because they are operating current assets to secure labor. In other words, this type of specialty contractors are focused on mobilization of labor not materials or equipment. So, it is determined that they will be able to increase revenue by operating current assets to address current liabilities and labor mobilization.

Recent trends in construction towards larger scale and taller buildings are causing problems by ineffective existing management approach in construction industry have emerged. Delivering necessary materials and mobilizing the human resources and equipment In a timely manner to keep labor on schedule have become a critical issue to be addressed. In particular, many specialty contractors carrying out multiple projects have been experiencing difficulties mobilizing the manpower on time and in right places due to poor communication at each stage of labor supply, resulting in waste of valuable resources. Hence, it's imperative for the specialty contractors to obtain specific information on labor demand so as to set up a communication and labor management system to ensure the right human resources will be mobilized in the right place at the right time. The study therefore is aimed at developing an optimal human resources management system for specialty contractors performing multiple projects. To that end, the study is focused on rebar and concrete work. The outcome of the study is expected to help allocate the right human resources to the right place in a timely fashion, thereby achieving an effective workflow at construction sites.

Business boundaries of firms in the construction industry are strictly regulated in Korea. Under the current law, firms involved in construction processes are classified into five categories; general contractors, specialty contractors, architects' offices, engineering firms, and specialized in inspection. Among these types of firms, general contractors are prohibited to enter into specialty contractor's market and vice versa by the basic law in the construction industry. Also general contractors are not allowed to provide architectural services. The purpose of the law is to prohibit unlicensed companies from entering the construction market and to protect customers. However, the law causes critical problems e.g. low efficiency of production and rent creation. Therefore, we identify problems concerning business boundaries of firms in the construction industry and predict structural changes in the them when they are liberalized. So we surveyed general contractors and specialty contractors in Korea to estimate the effects of the liberalization on the construction industry. Most of contractors point to the enhancement of production efficiency as the motivation to integrate other construction process. If current regulations, which limit firms' decisions on business boundaries, are eliminated, firms will choose optimal business scopes taking into account types of contracts adopted by the Government for public works. Based on the cost/benifit analyses, they will decide whether to intergrate other production processes or not.

The regulation of business area was abolished to improve the competitiveness of the construction industry and the ability of general and specialty contractors to enter the mutual market. As the next step, the government is preparing for a reorganization of business type. If the impact of the abolishing of business area on the construction industry is analyzed, the result can contribute to determining the step by step application scope of the reorganization of business type. This study derived the business types having a high probability of the mutual market entry of general and specialty contractors. Then, the size of mutual market entry is analyzed. First, the connection between the general and specialty construction, and the similarities between the registration standards of general and specialty construction are analyzed. Based on the result, a general contractor can enter 15 business types of specialty construction, and the market size is about 78.8 trillion KRW. This is about 82% of the total contract cost of specialty construction during the year 2017 (about 96 trillion KRW). Next, based on the relevance of business contents, the market size when general contractors enter the specialty construction market is analyzed. As a result, the market size is about 24.7 trillion KRW, and this is about 13% of total contract cost of general construction during the year 2017 (about 190 trillion KRW). Based on the result of this study, there is a higher probability of the mutual market entry of general contractors into specialty construction than vice versa. However, the result of this study is based on the current contents of business types, registration standards, and construction data of before abolishing the regulation of business area. This is a research limitation. If the business contents and registration standards are changed in the future, the result could differ from the current result.

This study suggests business strategies by interaction analysis of indicators related construction business and business performance for specialty contractors that provide labor, materials and small sized equipments. To do this research, the data was analyzed for construction orders and business performance indicators of specialty contractors with KRW 7 bil. or more of assets during 1997 through 2010. For specialty contractors that provide labor, materials and smaller sized equipments, the amount of construction orders affects profitability the most and therefore some sort of strategy needs to be established to respond to decrease in operating margin due to dwindling construction orders. In other words, it is determined that increase in the amount of construction orders enhances operation of gross assets as well as the operating margin, ultimately increasing the profitability.

The Construction Standard Production Unit(CSPU) has been used for the standard cost estimate in public and private construction projects. However, It is questionable if the reliability and/or authenticity of the system is acceptable due to the lack of consistent enactment and/or revision procedures. This study identifies informational conditions and issues relative to using daily work report as a data collection method for enacting and/or revising CSPU system, and establishes the measures for improving the daily work report. This study aims on the information constitution of daily job-site report, daily manpower report, wages register for specialty contractors. According to the research results, most of necessary data were included in a daily job-site report. In conclusion, it is investigated that data of daily manpower report and wage register need to be included in a daily job-site report for understanding the current state of worker 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.

Recently, there have been increasing studies on the application of digital technology, which has its focus of the irregular building. However, most of these studies have not clarified the objective of the technology and the effectiveness of professional manpower on its performance. This study analyzes actual used technology and the role of specialty contractor. It presents a framework to quantify the performance of the specialty contractor. For these purposes, this paper presents a proposed method to evaluate the activities of specialty contractors using a queueing model. As an attempt to verify the model, an actual irregular building project, in which digital fabrication is applied, is investigated during the construction phase. In order to collect the digital fabrication data, digital fabrication reports and specialty contractor's work log of project are reviewed. In addition, Digital Fabrication input personnel, productivity data are collected through interviews with experts involving in the case project. Analysis of specialty contractor's performance in digital fabrication reveals that the wait status of project participants varies probabilistically depending on the digital technology application level. The results of this study are expected to contribute toward the improvement of the production level in the construction industry.

In recent years, the number of construction projects carried out to repair and reinforce newly built structures and facilities has been on the rise compared to the number of new construction projects, accounting for more than 90 percents of all construction projects carried out by specialty construction companies. However, as some of the ordering parties fill out the required tasks incorrectly, the wrong information on construction bids is announced, and the specialty construction companies that hold a license and technology are unable to get the job at the right time. As such, it is critical to prevent unnecessary time and expense related to the correction of incorrect bid announcements by providing accurate information and definitions, because the tasks of each specialty construction work stipulated in the framework act of construction industry are vague. Therefore, the causes and problems were analyzed based on the correction cases of bid information, and a plan that can address the problem will be proposed. The result of this study can be utilized as fundamental data to achieve an institutional improvement in the bidding service for the specialty construction companies.
