LAI Kwok-hung, Sammy - Gammon Construction Limited

SCA 2018 Construction Manager - Excellent Award

One Taikoo Place has been designed and constructed with sustainability at the centre throughout the whole project lifecycle. Sammy LAI led a buildability study to promote sustainable construction at project pre-tendering stages. His adoption of total system formwork approach and tailor-made self-climbing formwork hoist significantly increase the productivity to achieve 4-day construction cycle, while reducing the consumption of timber materials and carbon emission from materials transportation and lifting. He actively promotes innovation technologies in the project site, the application of Artificial Intelligence, Virtual Reality and Robotics are shaping the future sustainable development of construction industry.

Modular design and construction has been adopted for this project. The structural steelwork for the walkway including the cleats for the façade elements and MEP components (approx. 400 tons) was prefabricated into segment and pre-assemble in PRC. The above can ensure the quality and tolerance are within the design requirement prior to deliver to site and minimize the on site installation work and FRP touch up works.

The project team has integrated cutting-edge technologies (3D Scanning, Virtual Reality, and Artificial Intelligence) with BIM System throughout whole building lifecycle, which virtualizes design development, increases overall productivity, and facilitates future buiding operation.

Innovative mechanical device - Zero Gravity (ZeroG) Arm is being applied to reduce stress and improve the productivity of our workers during prolonged drilling and fixing works at wall and ceiling. Total system formwork was applied for concrete casting to achieve 4 days cycle of concreting. We adopted the tableorm to reduce the amount of timber formwork erection on site.

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.

Why the Industry Needs Green Finance?

  • Green finance providing benefits for assisting the transition from the ‘brown’ to the ‘green’ construction.
  • Green finance can mobilise capital for green and low carbon investments in the construction industry
  • Stakeholders can seek opportunities for long pay back initiatives and low interest rates when adopting advanced and innovative measures.
  • To encourage investors from the Mainland along the Belt and Road as well as international investors to arrange green financing through Hong Kong construction capital markets.

Components of Green Bond/Loan Principles

images/Principles1.png

Green bond/ loan proceeds are to be applied for environmental (or “green”) projects with an indicative list of eligible project categories. See the figure below for the 10 eligible Green Project Categories.

images/Principles2.png

Recommends issuers/ borrowers to disclose their overall green objectives, the process used to determine eligibility of green projects, and the process to manage environmental and social risks of these projects.

images/Principles3.png

The net proceeds of the Green Bond/ Loan, or an amount equal to these net proceeds, should be credited to a sub-account, moved to a sub-portfolio or otherwise tracked by the issuer/ borrower in an appropriate manner, and attested to by the issuer/ borrower in a formal internal process linked to the issuer’s/ borrower’s lending and investment operations for green projects.

Recommends annual reporting of the amounts allocated and results of the eligible green projects.
