In order to comply with the Disability Discrimination Ordinance,the Govern-ment of the Hong Kong Special Administrative Region (HKSAR) has been retrofitting lifts and/or standard ramps to existing public footbridges,elevated walkways and subways for years if they are not equipped with standard barrier-free access (BFA) facilities and are technically feasible for accommodating such works.In addition,another condition needs to be fulfill is that there are no proper barrier-free pedestrian crossing facilities,either an at-grade crossing or a barrier-free grade-separated walkway,available within about 100 metres from these public walkways.In response to public request in recent years,the HKSAR Government has,since August 2012,launched a policy to retrofit BFA facilities at public walkways,striving to create a "universally accessible" environment for the public under the programme of Universal Access Facilities (UAF).Under the policy,rather than giving the provision of ramps a priority over lifts,lifts and ramps will be treated on an equal basis.In other words,as long as site conditions permit,the Government will consider retrofitting lifts at walkways even they are already equippedwith standard ramps.The implementation of UAF in Hong Kong has to face a lot of challenges including means to tackle heavy utilities congested areas,approach to minimize public nuisances,methods to achieve the construction works within reasonable time,innovative lifts design to in-tegrate with the surroundings and the strategy to win public support.This paper aims to introduce the effort that the consultants have made in Hong Kong to overcome such chal-lenges to complete the UAF projects.On completion of the UAF,we could enable the disabled and the elderly to cross the road easily,safely and comfortably by using the foot-bridges and subways.
