The Greater Bangkok Plan 2533 produced by the Litchfield team in
1960 was never implemented. In 1963 Cyrus Nims, the USOM (United
States Overseas Mission) city planning adviser to the Thai government,
noted that effective implementation of the plan required adequate enforcement
powers and an effective planning authority for a capital district
encompassing Bangkok, Thonburi and surrounding provinces. Above all,
the task required coordination between numerous agencies in national
government. Nim’s evaluation was pessimistic – coordination among agencies was not evident, a new city planning office languished as a minor
section of the Ministry of the Interior, and the national government was
choosing to ignore the plan’s recommendations (Nims 1963: 104).
