Core Tech International Corp.

Core Tech maintains a high level of work by fostering strong communication. For Core Tech International Corp., the key to success is its combination of “care, passion, dedication, hard work and cooperation among all our workers, from top management to our construction labor,” President Ho S. Eun says. “We work for a common goal, and we do our best to get there.”

Based in Tiyan, Guam, the general contractor specializes in single and multifamily residential, government infrastructure and facility improvement projects. Core Tech was originally known as Sun Woo Corp., which was formed in 1991. The family owned and operated general contractor completed commercial, office, retail and residential projects.

Over the years, Sun Woo gained a reputation for its high quality work. Meanwhile, in March 1998, Eun created Core Tech International Corp., which specializes in civil works, infrastructure and facilities improvement projects.

Sun Woo Corp. and Core Tech International, which were both owned by Eun, officially merged in 1999 as one entity to simplify its operation, which is now known as Core Tech International.

To date, the company has completed 164 Department of Defense projects, as well as numerous projects for Guam’s local government and private sector. Last year, the company enjoyed $41 million in sales, Eun adds.

He notes that Core Tech excels in planning, estimating, engineering and construction by hiring the right workers, selecting quality subcontractors and vendors, and maintaining close communication through project meetings and strategic planning sessions.

Fascinating Work

A graduate of Seoul National University, Eun holds a bachelor’s degree in political science. He started in the construction business at the age of 26. When he created Core Tech, Eun studied construction heavily because he had interest in the industry but lacked experience. However, the company has enabled him to pursue an industry that has interested him since childhood.

“When I was [5], I only played with wooden blocks where you can pile and create buildings,” he recalls. “I was always fascinated with buildings and structures.”

Complete Cooperation

Eun notes that Core Tech is proud of all of the projects in its portfolio, no matter their size. The company’s previous work includes $21.6 million worth of repairs and improvements for 99 housing units for NAVFACMAR in South Finegayan, Guam, which were completed in March 2006.

According to Core Tech, the improvements to the units included the installation of concrete roof slabs over front and rear patios, mirrored closet doors, ceramic tiles and vinyl composition floor tiles. The repairs included the replacement of worn-out architectural finishes, exterior and interior doors, windows, closet doors and shelves, and hot- and cold-water piping.

“We faced many challenges in renovating and improving the enlisted and officer housing units from demolition to finishing work,” Core Tech says, adding that its main challenge was maintaining a safe work environment on an occupied job site.

To accomplish this, Core Tech gave special consideration to work areas surrounded by occupied units. “Core Tech also had to make sure that there was minimal [disruption] to the residents while the construction was ongoing,” the company says.

“Although there was a set schedule of work for each cluster, actual construction was done based on the availability of units that were not occupied,” the company explains.

“Core Tech [also] faced the difficult challenge of maintaining and meeting the turnover schedules of finished houses based on schedule, while dealing with switching of units that were still occupied.”

Another challenge, the company notes, was a cement shortage on the island. However, in spite of all the obstacles, “There was perseverance, coordination and cooperation among all involved, allowing us to successfully complete the project within the contract period,” Core Tech says.

The company is now at work on the second phase of a similar $42 million project at a Guam naval base, which includes the demolition of 72 military family housing units and the construction of 59 new homes. The project is scheduled for completion in September.

Core Tech’s responsibilities on the naval project have included the abatement of asbestos, lead-based paint and the removal of chlordane contaminated soil under the building pad and the ground around the homes. ”The new housing units are located in a sloped part of the area, so protection of the environment was considered an important factor during the demolition and removal of contaminated soil,” Core Tech says.

Core Tech notes that its challenges on the project also include maintaining environmental safety. The company must address the possibility of soil erosion and the flow of contaminated water into an existing stream in any area where contaminated soil will be stored, the company explains.

The firm also is working on a $26.8 million project in Inarajan, Guam, that will see the construction of an access road sewer system for a municipal sanitary landfill. The project is scheduled for completion in April 2011.

At the onset of the construction project, Core Tech says it had to be careful in order not to encounter any resistance from the neighboring residents at the job site because constructing the landfill at Inarajan was not a very favored project by the residents in the area. However, “We maintained [a] good relationship with the people by hiring a lot of local workers to work at the site and supporting the community activities, such as fiesta and other festivities,” the company says.

Ready to Build

In the next few years, Core Tech expects its business to see a boom as the island prepares for a population increase. According to Public Radio International, the U.S. military will deploy thousands of Marines from Okinawa, Japan, to Guam.

With the move, the island is expected to see a rise in construction projects, which Core Tech expects to play “a major role in,” Eun says. He notes that the company and its affiliates have purchased several pieces of heavy equipment and service vehicles to support the projects, in addition to the purchase of a total of 75 acres of property that contains its work force housing facilities, which can accommodate more than 8,700 laborers.

The facilities are located strategically between the military work site at Apra Harbor, as well as Andersen Air Force Base and Finegayan in Guam. In addition, the company says, the structures are energy-efficient concrete structures that are designed to be a safe shelter from heavy winds and weather caused by typhoons and tropical storms common to the island.

According to the company, its acquisition of these facilities will ensure that no conflicts from perceived pay inequities, inconsistent management and safety standards, and other quality of life issues may arise from a mixed camp setting. This will facilitate a consistent culture of safety for all the workers.

Post-build-up plans for these properties would address affordable housing and public facility needs of the local population. “We are ready now,” Eun says. purchase of a total of 75 acres of property that contains its work force housing facilities, which can accommodate more than 8,700 laborers.
