The decline in the construction industry has led to a decrease the profitability of small and medium-sized landscape contractors. To relieve this situation, small and medium-sized landscape contractors have continued to proactively find ways to enter global construction markets. However, many small and medium-sized landscape contractors face risks due to their lack of capacity and insufficient preparations to extend the business abroad. Thus, this study aims to analyze the current condition of the Vietnamese construction market and the related risk factors. It then suggests strategies to improve the small and medium-sized landscape contractors' competitiveness in that market. We investigated the business climate and analyzed risk factors. Finally, we developed expansion strategies and conducted in-depth interviews with six overseas construction professionals. The study results first showed that efforts to improve infrastructure and the increased demand for housing in Vietnam will lead to more opportunities for small and medium-sized landscape contractors entering the Vietnamese construction market. However, changes in the Vietnamese business climate may act as a variable. Second, we found that small and medium-sized landscape contractors' risk factors are mainly related to laws and regulations, government finance, market fluctuations, public administration system, minimum wage increases, financing and bonds, contracting, trees and materials, and design errors. Finally, small and medium-sized landscape contractors are required to consider the following when seeking to enter the Vietnamese construction market: short-term strategy and mid-to-long-term strategy. This study will be used as the basis for small and medium-sized landscape contractors to plan to enter the Vietnamese construction market and to contribute to the expansion of the global construction market in the landscape industry.

현재 국내 건설기계 부품의 대부분이 수명 시간이 도래한 중고 장비가 동남아시아 등지로 재제조 되지 않고 수출되거나 폐기되고 있다. 이를 재제조함으로써 자원순환이란 관점에서의 많은 경제적 환경적 이점들을 충족하고자 하며, 선진국들과 중국도 일찍이 건설기계 부품 재제조 사업을 장려하고 있다. 재제조 사업은 부가가치가 높아 여러 국가의 유명 완성차 업체가 직접 참여하여 재제조함으로써 많은 건설 시공사와 수요처들에게 판매하고 있고, 수익성도 높아 완성차 제조 기업 중 재제조 사업으로 총 매출 중 20%를 차지할 만큼 적극적이다. 그러나 국내는 이제 2016년 건설기계 부품 재제조 협회를 창립하면서 음성적으로 재제조하여 왔던 기업을 양성화함은 물론 기반 인프라 구축을 통하여 선진 기업과의 조속히 격차를 줄여 나가고 있다. 또한 재제조에 대한 공정 기술을 개발함과 동시에 전국 인프라 구축을 통하여 산업의 활성화를 꾀하고자 건설기계 부품 산업의 발전 전략을 수립하여 본 기고에 제시하여 보았다.

Koran Government introduced BTL(Build-Transfer-Lease) to provide convenience through early supplying infrastructure and plans to invest 8,315million dollar to 84 projects of 15 BTL type involving official residence and railroad. But some of construction company hates to invest BTL projects because of its low earning rate. In addition if we correctively apply project which partly has profitability to BTL, the earnning rate declines more seriously. So this paper presents BTL+BTO model which operates BTL in the non-profitable parts to improve convenience of users and BTO in the profitable parts to improve earning rate. BTL+BTO model based on operate period was presented and its suitability was confirmed by applting 00 region official residence project.

This study analyzed the efficiency by using the DEA model to evaluate the competitiveness of specialty construction firms. The target of the analysis is 300 firms with continuous data from 2010 to 2017 as listed and externally listed firms. Significant analysis results are as follows. First, the efficiency of specialty construction firms is lower than that of general construction industry. Second, efficiency by type was highest in facilities construction and dismantling work. This shows that the relevant industries such as reinforced concrete works and scaffolding and demolition work are relatively efficient in specialty construction industry. Third, the efficiency of specialty construction industry is affected by economic fluctuations. When the construction industry is in the expansion phase, the efficiency value is high and the efficiency value is low in the down phase. Finally, in the scale profitability analysis, specialty construction industry was most analyzed by DRS. This means that it is effective to scale down for the efficiency of the firm.

Based on Income-approach, this study develops the evaluation model which reflects construction industry's traits. Using Income approach, we derive future income's present value and evaluates the technological value by contribution to future income. As there exist more random variables in construction technology than in standardized manufactured products, we cannot help relying on not only quantitative estimation method but also qualitative evaluation by technology and market experts when we estimates construction technology value. Also, conservative estimation is needed for discount rate and cash-flow estimation, because of high uncertainty in sales and profits in construction industry. In empirical analysis, we applied economic periods of duration and cash-flow based on the standard guideline, and analyzed discount rate and technology factor based on characteristics of construction industry. The discount rate is estimated to 15% because of risk-premium increase by conservative evaluation. Technology factor is estimated to 46.7%, because technological intensity is estimated to 72% by technological superiority. Such implications can be inferred. Firstly, we need to build a database to diversify categories for division of sectors by activity or industrial classification which is now categorized only by two sectors in standard guideline. Secondly, the roles of experts who participate in technology evaluation are important because of volatility of construction technology.

The government wants to apply the construction cost estimating method based on historical data published in the first six months of 2004. Construction companies, however, require the proposed cost estimation model, to be improved which makes it difficult to predict a reasonable construction costs. This paper presents an improved historical data selection model after analyzing the problem of previous method throughout comparing contracted unit prices of reinforced concrete works selected by the previous model to market prices. The model which can select more feasible data would assist participates such as general contractors and sub-contractors to earn a proper profits.

Since the early 1990s, Korean construction companies have strived to evolve into global Engineering Construction (EC) companies. However, such efforts have been unsuccessful, partly due to a lack of clear objectives and a misunderstanding of the direction that needed to be taken for such a change. A better understanding is required with respect to the need to transform into an EC company in the context of the rapidly changing global construction environment. This research investigates major EC companies from around the world, and assesses the status of domestic companies' efforts for EC transition. The results of these investigations revealed that domestic firms need to better prioritize their strengths for different markets, i.e., decide whether to implement directly, outsource or limit to process management. In addition, the investigations showed that the global market is shifting from monolithic projects to more complex projects. Such projects require firms with the ability to develop and implement high front-end investment strategies, planning capabilities, and pre-design management skills. Accordingly, we recommend that firms differentiate themselves by developing such a skill set required for specific products.

This study undertakes a comparative analysis of the correlation between the condition of the domestic construction market and the expansion of overseas projects within construction companies, based on the vector error correction model. The analysis results verified that, in the post-IMF crisis period, domestic construction companies took on more overseas projects only when the residential construction market slowed down. Compared to the pre-crisis period, construction companies grew more responsive to the condition of the domestic market for residential construction, and they took on more overseas construction projects when the domestic market slumped. This is because the business portfolios of Korean construction companies' render them highly vulnerable to the condition of the residential construction market. When the domestic residential market slows down, the business condition of construction companies quickly takes a turn for the worse, and to cope with this, they turn to overseas projects to compensate for the slowing of the domestic market. As the analysis shows, expanding overseas construction projects as a way to turn around business condition amid a slow residential construction market actually undermines the management of the companies even further. In other words, shifting business focus toward an overseas market during a hard time might be useful for securing cash flow, but might not help to restore profitability. Thus, construction companies need to carefully manage their level of business diversification to ensure strategic flexibility.
