002/19-09-2007-ECCC-OCIJ ЮŲŠ / No: D427 335. The people working at Trapeang Thma came from the villages of the districts of Sector 5 of the Northwest Zone, including Thma Puok District, Phnom Srok District, Serei Saophan District and Preah Net Preah District.1378 The workers also included “new people” who had been moved from Phnom Penh1379 and from Siem Reap.1380 336. Workers comprised men, women and children;1381 and were organised into work units. The working units each comprised approximately 10 people forming part of larger platoons, companies and battalions, comprising 30, 100 and 300 people respectively.1382 The “mobile units” contained “middle aged people”.1383 Certain units were of mixed sex; in others, the workers were organised by sex but there were no differences in the assigned tasks.1384 Workers in the mobile units were required to build the dam, dig canals, build irrigation systems, grow and transplant rice.1385 The “children’s units” comprised 13 to 17 year olds.1386 The children in the children’s units were separated from their families and made to live together with their unit members.1387 Furthermore, there were “Special Case Units” where those considered to be avoiding work or of having an “ideological disease” were placed for observation and reeducation.1388 The “Special Case Unit” had the highest work quotas1389 and those whom it was considered could not be reeducated in the Unit would disappear and never be seen again.1390 337. The dam was built almost exclusively by manual labour,1391 with quotas from 1 cubic metre up to 3.5 cubic metres of earth to dig per day per worker.1392 Some machinery appears to have been used, but only for secondary tasks, such as tractors to assist in leveling the ground.1393 338. Although it may have varied in different working units, working hours at Trapeang Thma were approximately 7am to 11am and then from 1pm until 5pm.1394 Some witnesses also refer to working hours during the nightime, from about 7pm until 10pm or later especially when quotas had not been met.1395 Some units started work earlier in the morning with one witness stating that they started at dawn.1396 No rest or breaks were allowed before the assigned task was completed.1397 Workers who completed their quotas would then be given extra quotas to complete.1398 Although some witnesses state that there was no punishment inflicted for those who could not meet their quotas,1399 it is more likely that workers were punished,1400 either physically1401 or with the reduction of food rations.1402 Other workers who did not meet their quotas would be sent to reeducation or refashioning meetings1403 or to the “Special Case Unit”.1404 339. Workers were not allowed to stop and rest during working hours.1405 Most of the witnesses say they were forbidden to talk with each other.1406 Short breaks to drink or urinate were Extraordinary Chambers in the Courts of Cambodia, National Road 4, Choam Chao, Dangkao Phnom Penh Mailing address: P.O.
