Howe had worked in the
Civil Service for almost 30 years. He began his career as a teacher, then was a broadcaster for a period before taking the post of an administrative officer in the
British Colonial Secretariat. Howe was subsequently appointed as a
police magistrate and later secretary to
Public Service Commission (PSC). In 1960, Howe became the inaugural CEO of the
Housing and Development Board (HDB). He was Chairman and
President of the
DBS Bank between 1970 and 1979, inaugural Chairman of the
PSA International,
Permanent Secretary in the
Prime Minister's Office (PMO), and the head of the
Singapore Civil Service. During his tenure as a senior civil servant, Howe played a leading role in several of Singapore's iconic infrastructural projects like the
Mass Rapid Transit (MRT),
Singapore Changi Airport and
public housing. Known by his colleagues from the civil service as a fierce, tough-talking man, Howe debated vehemently with former
Deputy Prime Minister Goh Keng Swee over whether to build the MRT system in Singapore. Howe was strongly in favour of the MRT as the backbone of
Singapore's public transport system, while Goh proposed a more economical all-bus alternative. Howe fought strongly against the extension plans for a second runway at
Paya Lebar Airport, and advocated the building of a new
international airport in Changi. This was despite the Cabinet's decision for the go-ahead in 1972, based on a British expert's report that it would cost less to expand Paya Lebar Airport and that there was not enough time to get Changi built up to meet increasing traffic needs. Howe gathered a team to
reclaim land, widened and extended the old
Royal Air Force airstrip to take
Boeing 747s and build the terminal. In August 1981, operations stopped overnight at Paya Lebar Airport and restarted the next morning at Changi Airport. Howe's role in setting up Changi Airport won him credit in Lee Kuan Yew's memoirs. Howe also fast-tracked the public housing programme while serving as the CEO of HDB under Chairman
Lim Kim San in the early years, solving the chronic housing shortage in the 1960s. As Chairman of PSA, Howe went against the advice of professionals to build Singapore's first
container terminal in the early 1970s. In 1991, Howe helped to set up a managed fund, the Mendaki Growth Fund, for the
Malay self-help group Mendaki, the Council for the Development of Singapore Muslim Community. ==Political career==
