DICKSON Construction has been awarded an $86 million government contract to improve group check-in facilities and build a bus dock and arrival escalators at Kai Tak airport. The company has also won two port work contracts worth about $130 million at Nim Wan and site formation for Tuen Mun Area 38 last month. And on Friday, the group will link with Sino Group to bid for a job building a $200 million toll station in Tung Chung. Dickson will hold a 70 per cent stake in the venture. But the firm sees bigger windfalls from the Government's infrastructure projects, to be awarded in the next three years. ''As more infrastructure projects will be launched in the next few years in Hong Kong, more government contracts will be awarded. The construction industry is therefore getting more prosperous,'' said Henry Sun, general manager of Dickson Construction's investment division. Mr Sun attributed the surge in the number of listings of construction companies to the start of large government building projects, such as the recently announced Central and Wan Chai reclamation work. Next month, Dickson will bid for an environmental project in Yuen Long. The group said it would invest in a commercial and residential project in Zhongshan, Guangdong. Dickson Construction has expanded its fleet by spending $50 million on a grab dredger and four barges, ready for the substantial port projects coming up. ''Other than carrying out construction work generated from bids won by Dickson, the fleet can be leased to third parties, which ensures a good return of between 20 and 30 per cent,'' said Mr Sun.
