The 4th IPA International Workshop was held at a hotel in Singapore, Mandarin Orchard Singapore, on December 6 and 7.
About 240 researchers and engineers from 6 nations participated. With great supports from National University of Singapore,Geotechnical Society of Singapore, major construction engineering companies, general contractors, subcontractors, trading
companies and manufacturers of the steel products, the conference was completed with substantial content and size.
In the workshop, a variety of presentations were made from different point of views; fundamental researches on press-inengineering theories, press-in construction examples and so on. On the final day, a tour of two press-in construction sites - a
private construction site of a highrise condominium and a public construction site of a drainage - was hosted by two local
enterprises, where all the participants felt in their bodies the superiority of the Press-in Method that obeys Five Principles ofConstruction. The research grant award ceremony and research presentations by the previously granted three investigators
were held as well, in accordance with custom. The participants enjoyed these programs of uniting the theory and the practice,which is the essence of IPA.

Singapore has been rapidly developing as a core country of Asia and is an international city that is playing an important role in
information transmission as well as in economical activities. It can be expected that this opportunity of transmitting the latest
information on press-in engineering should promote the recognition of press-in engineering and the speedy progress of theresearches.

Updated: 18 Jan 2013

Tour of press-in construction site (1) Construction site of highrise condominium (December 7, 2012)
Name of construction:
Construction of Highrise Condominium with 27 Stories
Main contractor:
V3 CONSTRUCTION PTE LTD
Piling contractor:
Guan Chuan Engineering Construction Pte Ltd
Objectives of construction:
Temporary retaining wall for constructing underground carpark(B1)
Press-in machine:
Silent Piler SCU-ECO400S, SA150
Press-in material:
Sheet pile type IIIA, L=9.0-12.0m, N=600

On December 7, the second day of the workshop, a tour of two press-in construction site was held. The first site was theconstruction site of a highrise condominium, where press-in piling was conducted by Guan Chuan Engineering Construction PteLtd, one of the supporters of this IPA workshop. Sheet piles were pressed-in to build the temporary retaining wall for theconstruction of the underground car park. Due to the conditions that the site is in the city area and that the subway is runningabout 18m below the adjacent street, the environmentally friendly Press-in Method had been adopted.
Although it was not possible to get into the site, the participants were able to observe the whole site from the fourth story of thechurch beside the site, through the courtesy of that church. The general information of the construction was provided byPresident David Liaw Wie Sein, and lively questions and answers followed. Two press-in machines (a machine for standard
press-in and a machine for Hard Ground Press-in Method) were placed together, so that the difference of the two penetration
systems could be easily understood.

4Tour of press-in construction site (2) Construction site of drainage (December 7, 2012)
Name of construction:
Drainage Construction at Tuas
Main contractor:
SHANGHAI TUNNEL ENGINEERING CO LTD
Piling contractor:
Eng Lee Engineering Pte Ltd
Objectives of construction:
Temporary retaining wall for constructing drainage
Press-in machine:
Silent Piler SCU-400M
Press-in material:
Sheet pile type IV, L=9.0-12.0m, N=6,000

The second site was the public construction site of a drainage, where the press-in piling was conducted by Eng Lee Engineering
Pte Ltd, one of the supporters of this IPA workshop. A temporary retaining wall to replace the existing channel with a larger box
culvert is under construction as a countermeasure against flood. The construction area had been restricted due to the adjacentfactory and trunk road. The Press-in Method was adopted because it is environmentally friendly, requires no temporary works
and assures safety. The Crushpiler, the press-in machine for Hard Ground Press-in Method, was being in operation, as theground condition was hard with the layer of sandy silt with N value over 50.
The site was faced with a trunk road with a lot of traffic, and any passersby could see the piling work through fences around thesite. The participants were able to observe close up in detail the process of press-in piling from pre-augering to pressing-in of asheet pile, thanks to a special tent. In both sites, being filled with lively atmosphere, the participants were impressed with thesuperiority of the press-in machines, with its safe and silent motion, with its ability to save space and with its swift operation.
It was a rainy season in Singapore. The tour event had a narrow escape from a rain, but the staffs at sites had experienced
squalls with thunders during preparation until the previous day. Their dedication is really appreciated.
