Chun Wo Construction & Engineering Company Limited

SCA 2018 Contractor in New Works - Gold Award

Happy Valley Underground Stormwater Storage Scheme is designed to alleviate flood risk in the Happy Valley and Wan Chai area, the scheme involves construction of a 60,000m³ underground stormwater storage tank, a pump house, a fan room, a 650m long twin-cell box culvert and associated works including reinstatement of sports pitches and landscaping.

By applying the alternative foundation design, 2,000 tons of steel and 6,000m³ of grouting material has successfully abridged, it massively allows the project to shorten the construction period by 3 months and saved HKD$72M for the construction cost.

In addition, the treated harvested water would be reused on the sports pitches and public toilets, resulting a maximum of 220,000m³ potable water saved annually.

About the Model

The HKSAR Chief Executive had announced in the 2017 Policy Address to position Hong Kong as an Asia’s green finance hub for raising green capital. In view of the substantial GDP contributed by the construction sector annually, the construction industry has a high potential to meet the trend of green finance. Thus, there is a need to well define the green standard and system to facilitate the application of green finance in construction industry.

The Model aims to act as an interactive guide on environmental practices and advanced technologies for construction projects which is compatible with international green bond/loan principle. Green finance can mobilise capital for green and low carbon investments in the construction industry. Public owners, developers, contractors and suppliers could issue green financial instruments for funding their projects with reference to the guideline of this model.
