Turnover at two SAR-listed construction companies - Wai Kee Holdings and Hsin Chong Construction Group - plunged 60.9 per cent and 23 per cent respectively in the half to September 30. However, Wai Kee managed to post a net profit gain, while Hsin Chong saw its losses widen. During the six-month period, revenues at Wai Kee were down to HK$700.44 million from HK$1.78 billion. The large drop was due partly to the substantial completion of major civil construction contracts, and as a result profit from its construction division was cut by about half to HK$16 million from HK$31 million a year ago. Despite the drop in sales, Wai Kee recorded a 61.5 per cent rise in net profit to HK$63.38 million, bolstered by the contribution from Road King Infrastructure, a 49.08 per cent-owned subsidiary. Road King, which operates toll roads in the mainland, recorded an unaudited profit after tax of about HK$237 million in the nine months to September 30. It contributed about HK$58 million to the parent during the period. Wai Kee's profit growth was also due to a decision not to make another provision for a claim in relation to a public-housing piling project revealed as sub-standard in 1999. At Hsin Chong, turnover fell 23 per cent to HK$940.96 million in the half to September 30, from HK$1.22 billion in the same period last year. Associates' share of losses rocketed to HK$5.3 million from HK$251,000 previously. Thus its net loss widened six fold to HK$32.53 million from HK$6.4 million a year ago.
