A sales manager of an architect firm and two others have denied bribing office staff of the management of two residential buildings and a property management company employee of another building for securing consultancy contracts.

Century Architects sales manager Yeung Wai-wah, 33, construction company sales manager Cheung Man-tak, 40, and former senior property manager Chow Siu-hung, 50, pleaded not guilty to five corruption charges at Kowloon City Magistracy today.

Magistrate Ernest Lin adjourned the case to January 6 for a pre-trial review. The defendants were granted $30,000 bail each.

Yeung alone faces three charges of offering an advantage. One alleges Yeung offered a bribe, equivalent to the share of costs towards the maintenance fee contributed by each resident of Woosung House in Jordan, to the vice-chairman of the incorporated owners for assisting Century to procure a consultancy contract of the building.

The second charge alleges Yeung offered $2,000 to a part-time clerk employed by the incorporated owners of Wing Shing House in Tsz Wan Shan for securing a canopy maintenance consultancy contract.

Yeung also allegedly offered a large sum of money to the property management employee for helping Century in boosting the extent of a renovation project at On Hong Mansion in Tsz Wan Shan.

Yeung and Cheung together face a count of conspiracy to offer a sum between $20,000 and $50,000 to the part-time clerk of Wing Shing House, as reward for assisting Century in securing a canopy maintenance consultancy contract.

Chow was charged with one count of offering $4,000 to the part-time clerk for a similar reason.

The alleged offences took place between March 2002 and September 2004.
