In the previous comparative studies of international competitiveness conducted before 2003, Korean construction productivity had been estimated to be lower (or poor) than that of developed countries such as US, UK, and Japan. However, the amount of international contracts Korean has won increased substantially, and Korean construction has progressed with creating two skyscrapers such as Petronas Tower and Burj Dubai. At this point we need to reevaluate what we are capable of. In this paper, we evaluated international competitiveness of our construction industry comparing to advanced countries by analyzing labor productivity. For evaluating construction competitiveness we measured labor productivity using the value of construction work in US dollar per hour based on domestic and foreign statistical data and analyzing completion days per a story and the ratio of underground floors to ground floors of buildings in Korea and Japan. As a result, although our construction productivity is not yet competitive with the US and Japan yet, we excel the UK.

국내 주거의 주종인 아파트의 구조형식은 벽식 철근콘크리트조로 경제성 때문에 대부분 고층으로 지어지고 있다. 철근 콘크리트구조 건물을 구체공사비중 상당부분이 거푸집공사에 투입되고 있다. 구체공사의 공기(工期)는 층당 소요일수로 산정할 수 있는데 공사비 절감 및 공기단축을 통한 시공효율상의 향상을 위해서는 지주시스템의 효율적인 전용(轉用)이 필수적이라 할 수 있다. 본 연구에서는 벽식구조 아파트의 현장조사를 토대로, 현재 사용되고 있는 지주시스템 및 바닥슬래브에 대한 응력해석을 수행하고, 이를 분석하여 공기단축의 가능성을 검토하였다.

To improve productivity in the architecture, construction and engineering industry, it is critical to understand both current and historic trends in construction productivity. This study analyzes and compares construction productivity trends of South Korea, the U.S., the U.K., and Japan 1995 to 2015 using the following three measures: construction labor productivity, construction duration per floor, and construction duration per 1,000 m2 floor area. As the results, the international competitiveness of each country varied according to which measures were used to analyze them. Among the four countries, the construction labor productivity of the U.S. was the highest, followed by that of South Korea. South Korea also had the second highest productivity growth rate, following that of Japan. On the other hand, when analyzed from the perspective of construction duration, the construction productivity in South Korea appeared relatively lower than those of other countries. There were differences in the location of construction competitiveness of each country analyzed by various measures. Therefore, to accurately diagnose and improve the construction competitiveness in South Korea, strategies based on various measures are need to established simultaneously.
