GREEN WALLS AND NOISE BARRIERS
1.1
Greening and Noise Barrier Experience
1.1.1
Urbis has extensive experience working in Hong Kong and for Highways
Department, particularly on noise barriers and on greening techniques. Most relevant to this project is Urbis’ experience in conducting the ‘Investigation Study for Greening and Aesthetic Design of Noise Barriers’ for HyD in 2006 (agreement
No. HMW 1/2005(EP)). Also of great significance is Urbis’ experience for ASD in conducting the Study on ‘Green Roof Application in Hong Kong’, which has become a public document.
1.1.2
In addition to these studies Urbis have been involved with a number of practical projects. In the past, Urbis was involved with the cut-and-covered greened noise barrier on Route 8 (in Sha Tin Heights) and with innovative design proposals for noise barriers in the West Kowloon Reclamation area. Currently, Urbis is involved with the Retrofitting of noise barriers on 13 Existing Road Sections throughout
Hong Kong (agreement No. HMW 1/2005(EP) and with noise barrier designs for
MTRC railway projects such as new The Express Rail, and Sha Tin to Central
Lines.
