The government is under pressure to do a U-turn and increase commercial space along the new Central waterfront.
Consortiums seeking to develop the waterfront say the limited commercial space, and conditions attached to the project, make it financially unviable.
The government and the Harbourfront Commission recently began negotiating with potential bidders to develop the waterfront.
People familiar with the situation said that, because of the concerns these consortiums have raised, the Development Bureau is considering ways to make the project more attractive.
The options include injecting public money, increasing the amount of commercial space and extending the period of waterfront land leases to give the winning bidders more time to recover their costs and make a profit.
The waterfront project comprises two sites. The successful bidders will be asked to design, build and operate facilities there.
