C O N T E N T S The 21st century already has seen significant changes in the global construction

industry. The traditional demographics and differentiators are no longer. The

Middle East, China and India are the new centers of the global construction

market. Consolidation has created fewer and larger global construction

companies. Currency fluctuations and shortages of labor and material are

putting added pressure on contractors.

Dong Ah Construction, since its establishment in 1945, has demonstrated great

ability in the domestic and international construction market. The company

began with major civil engineering projects in constructing dams, harbors,

highways, land reclamation projects and landfills. Later activities expanded to

include projects such as thermal and nuclear power plants. Dong Ah was a

significant force in the expansion of the Korean economy and did much to

improve the lives of the Korean people through social and urban projects.

Water/waste projects and other environmental construction helped to broaden

Dong Ah’s market. The success of its domestic operations provided the impetus

for expansion overseas and led to execution of major overseas civil construction

projects in the Middle East and Africa, particularly in Saudi Arabia and Libya.

Dong Ah also did major projects in S.E. Asia. The company looks with renewed

confidence to the 21st century with strong corporate core values and a clear

vision of our mission.

synergies with Prime. Dong Ah will launch a new initiative to regain our positon as a global construction company.

We will be leaders in creativity

Dong Ah will continue to rely on our core staff. Turnover is low and retention is high because respect and in-house

training are stressed. Communication is essential to a global company. Information is open and consistent. We

embrace the need for cultural diversity and we have foreign employees and consultants. Relationships with other

global companies and specialty groups add further competencies. We create and nurture a creative and lively

business culture.
