1. Samut Prakan Wastewater Management Project
Client: Nippon Comsys
Consultant: Atkins
Suppliers: Nippon Hume, CP&P
Project Description:
This was an approx. US$750million project funded by the Thai Government with assistance from the ADB and JBIC. Euro Iseki worked on a number of sub-contracts on this project as a specialist sub-contractor for pipejacking and manhole construction. Our major contract, SC27 & 28, involved almost 200 shafts and almost 20km of pipejacking from 300mm to 1800mm diamater, in marine clay. The shafts, consisting of HDPE-lined precast units, were then converted into permanent manholes.

Scope of Works:
- Land & marine-based shaft construction using precast-caisson sinking method
- Slurry-system pipejacking
- EPB pipejacking with muck-pump
- Manual-excavation pipejacking
- Grouting
- Manhole & Interceptor chamber construction
A typical shaft location in the centre of a busy Bangkok road.
A cutting edge unit ready for the guide collar to be cast.
1200mm pipejacking from a 3.5m sq. HDPE-lined precast shaft located in a canal in Bangkok.
Benching formwork being placed in a shaft similar to above.I was also involved with Contracts SC24, 25, 26 and 47 for clients Nawarat and Pipejack International.
Client: Skanska
Project Description:
This project involved the construction of interceptor chambers over existing combined drains and sewer pipes. The flow was then diverted into a new sewer system located within the canals and channeled toa new pump station and treatment plant. Our contract involved the construction of numerous shafts upwards from 2m dia. inside the canals. These shafts were constructed from within over-sized steel tubes and some were accessed from temporary steel platforms resting on H-piles driven into the canal bed. Pipelines consisted of HDPE pipes laid using the very effective Bohrtec pilot-tube system.

Due to a downturn in work volume, and expats being a relatively high-cost, I was made redundant in April 2003. I intended to move to Malaysia to work on a project for Shimizu Corporation, but had to return to the UK temporarily due to a delay to the start of that project.Dates: April 1999 - April 2000
