On December 7, the second day of the workshop, a tour of two press-in construction site was held. The first site was the construction site of a highrise condominium, where press-in piling was conducted by Guan Chuan Engineering Construction Pte Ltd, one of the supporters of this IPA workshop. Sheet piles were pressed-in to build the temporary retaining wall for the construction of the underground car park. Due to the conditions that the site is in the city area and that the subway is running about 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 the church beside the site, through the courtesy of that church. The general information of the construction was provided by President 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.

Tour of press-in construction site (2) Construction site of drainage (December 7, 2012)

Tour of press-in construction site (2)-1
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 adjacent factory 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 the ground 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 the site. The participants were able to observe close up in detail the process of press-in piling from pre-augering to pressing-in of a sheet pile, thanks to a special tent. In both sites, being filled with lively atmosphere, the participants were impressed with the superiority 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.
