CONSTRUCTION OF CONTAINER TERMINAL NO. 9 KWAI CHUNG, HONG KONG
This presentation describes the Design and Construction of Container Terminal No. 9, the latest extension to Hong Kong’s container port facilities.
This extension is the largest extension, adding 6 No. berths for Panamax container ships and 68 hectares of Back-up area for container handling. In addition, the reclamation works have reclaimed land for container storage, access roads and main drainage and land for the Stonecutter Bridge.
ABOUT THE SPEAKER
John Kenneth Mundy is a C Eng., FICE., MIStructE., MIES. He was awarded the ICE Thomas Telford Gold Medal in 1989.
Following a substantial career engaged on infrastructure projects in the UK, Mr. Mundy moved to Hong Kong in the early 1980’s and was the Project Manager on various infrastructure projects including the construction of a 5 level station concourse structure for the Mass Transit Railway Corporation, 2 new pumping stations and intake tower structure with shafts and tunnels at Plover Cove Reservoir for the Water Supplies Department of the Hong Kong Government, a 4 km long twin bore dual lane road tunnel for the Highways Department, a 5.5 km long rail tunnel for Kowloon Canton Railway Corporation. Both tunnels connecting the Kowloon area to the New Territories.
In addition he was the Project Manager for the construction of Western Harbour Crossing, a dual three lane immersed tube road tunnel connecting Kowloon to Hong Kong Island, a BOT project part of the Hong Kong Airport Core Programme.
Additionally, during his career in Hong Kong, he was the Project Manager for the construction of the last two extensions to the Kwai Chung Container Port Facility: Terminal 8, a four berth Panamax container ship berthing facility with 55 hectares of backup area, and Terminal 9, a six berth Panamax container ship berthing facility with 65 hectares of backup area.
More recently he was an Advisor to the Contractor involved in the construction of a 30km elevated railway viaduct project with 21 No. stations from Noida to Greater Noida in Uttar Pradesh, India.
GROUND IMPROVEMENT USING VIBRO TECHNIQUES
When weak soil is encountered, pile foundations are often considered first. However, some soil and loading conditions may require ground improvement which utilizes in-situ soil as a source of environmental friendly solution at a faster construction speed. It may be more cost-effective.
Vibro techniques which are widely used in Singapore and this region are considered part of the family of ground improvement techniques. While reclaimed or in-situ sand is normally loose, it cannot support the targeted structures. However, with the utilization of vibro compaction which will hasten the densification, it is quickly densified, allowing it to structures support that are of medium level of loading.
Clays that are soft or firm can be supported by stone columns. During this talk, fundamental vibro techniques will be explained, followed by actual case studies for chemical plants and oil storage tanks.
ABOUT THE SPEKAER
Dr He Zhi Wei graduated with a bachelor’s degree in engineering from Tsinghua University, Beijing (1991) and PhD in Geotechnical Engineering from the National University of Singapore (2009). He is currently Design Manager of Keller Foundations (S E Asia) Pte Ltd.
He has been involved in many large projects for ground improvement, such as Punggol Waterway, LanXess rubber plant, Keppel Merlimau power plant, Evonik chemical plant, Vale Malaysia mega storage yard, Jurong Shipyard hull shop at Tuas, Nghi Son refinery Plant in Vietnam, Changi Airport expansion, Neste Biodiesel plant expansion and ExxonMobil CRISP project.
The ground improvement techniques used are vibro compaction, vibro stone column, vibro concrete column, deep soil mixing, mass soil mixing, jet grouting and PVD for these projects
SEVERAL SUGGESTIONS ON FOUNDATIONS, RETAINING WALLS AND SHORE PROTECTION FOR SINGAPORE SOUTHERN WATERFRONT DEVELOPMENT AT EXISTING SINGAPORE PORT LANDS
URA has published the future Southern Waterfront Development Master Plan. Most of the areas involved are located at existing port lands of Tanjong Pagar, Keppel and Brani.
In this webinar , the speaker will discuss and suggest the following on the future development:
(i)The wharf apron areas supported by piles or concrete blockwork quaywalls thus existing wharf decks have to be removed due to corrosion and design life
(ii)Obstructions below the existing wharf decks, i.e. Toe Bunds, etc., should be removed for installation of new piles in future
(iii)Instead of reclaiming, the use of piles and basements of the buildings and structures may be seated directly onto the existing seabed
(iv)New basement walls and concrete infilled cofferdams may be used as new shore protection structures.
The objective is to achieve the Optimum Schemes.
