Tunneling is a critical component of any transportation system. With MAA’s substantial knowledge and experience in geotechnical, structural and construction engineering, MAA has been providing full service in tunneling design (including the use of seismic, FEM, geological and structural analyses) under many different soil and rock conditions. One of the most notable project is the Fushing North Road Underpass through Taipei’s Song Shan International Airport. The project is the first of its kind in the world where a tunnel will cross under an operating runway with a very strict settlement control of less than 2.5 cm. The project utilized the Endless Self Advancing method, which is the first of its kind in Taiwan. Other participated projects include Taiwan High Speed Rail (19 contracts with a total 13 km long) and Hsinyi Bypass of the Second National Freeway (8 km long trunk line and two side cable boxes with a total length of 7.5 km).
