Since the start of operations in 1965, the Singapore Office has distinguished itself with numerous successful diverse projects. The East Coast Reclamation project began in 1965 and was Obayashi’s first major overseas civil engineering project in Singapore. Upon completion of the 20 year project in 1985, a total of 1,114 hectares (1.8% of Singapore’s land mass) had been reclaimed. Obayashi Singapore Office has also contributed to Singapore’s landmark skyline with the construction of skyscrapers such as the Treasury Building (1986), SIA Building (1997), One Raffles Quay (2006), Ocean Financial Centre (2011) and Straits Trading Building (2009).
