Also we service to meet the needs of tunnel-construction related mechanical facilities of ventilation,
water supply, water drainage, dirty/gray water treatment, and etc. Since we service for civil engineering related mechanical facilities, we are referred as division of civil mechanical engineering and design of our company.

We have reinforced our sales activity in 2001. We have improved to turn out in 2004 100 services
and achieved accumulated road length of 302.8 Km. Our division is consisted of design team and technical support team (TST).

TST of our company is fully able and capable internally to conduct computer simulation or CFD (Computation Fluid Dynamics) without buying 3rd party’s consulting.

On-hand project service.

Our on-hand jobs in 2005 is summarized as follows:

Our two teams with three or four engineers in each team under top class engineers as team manager
with over 10 year design experience will continue developing wider range and various kinds of new
business. Our teams will keep expanding current scope of business items to test, adjustment,
balancing, and supervision as well as design of ventilation and fire protection system in tunnels and
underground spaces.

Our team will continue advancing into future possibilities based on never giving in pioneer spirit and
unyielding integrity instead of entertaining ourselves by today's output.
