Witness testimony varies, some stating that construction commenced in early 1976,1337 others that it commenced between late 1976 and early 1977,1338 whilst other witnesses state that the dam was constructed entirely in 1977.1339 Nevertheless, almost all evidence supports that the completion of the dam had largely taken place by the end of 1977,1340 or at the latest by May 1978.1341 It was officially described by the CPK in October 1977 as the result of a nation-wide labour offensive to fulfill the CPK’s 1977 economic plan, pursuant to a policy according to which the workers had “sacrificed everything for maximum rice production”.1342 325. An inauguration ceremony was held at the dam in December 1977 which was attended by various senior level CPK cadres. It was presided over by Pol Pot accompanied by a Chinese delegation as reported in the Chinese press.1343 Heng Rin alias Mei alias Neou Rin, Sector Secretary, and Cheal from the Sector Committee,1344 were the other CPK cadres from the Sector 5 Committee attending this ceremony. 326. Upon completion, the size of the dam was approximately 10 metres wide at the top, 18 metres wide at the base and between three to five metres high.1345 The water contained by the dam extended approximately 10km in length by seven km in width.1346 Functioning Structure and Personnel 327. The construction of Trapeang Thma was organised and controlled by CPK cadres who divided and supervised the workers into working units, assigned unit tasks and individual tasks, issued working plans, appointed unit leaders,1347 and collected biographies of people working at the site.1348 There were unit chairmen, company chairmen and platoon chairmen within the reporting structure.1349 328.
