Abstract： This paper introduces the construction accuracy management plan of the large-scale offshore trusstype aquaculture platform "Gesheng 1"， including the preliminary overal planning of construction accuracy design， accuracy control standards，shrinkage alowances，and margin schemes.The plan improved the fabrication accuracy of the platform's segments and the block assembly accuracy on the berth，reduced the re-cutting rate during block consolidation，and enhanced overallconstruction efciency.It summarizesand establishes a construction accuracy design standard for truss-type aquaculture platforms， providing areference for similar trusstel structures or ship/ offshore product constructions.

Key words： accuracy; margin; shrinkage allowance; truss-type; aquaculture platform
