A park will developed beneath the bridge

Details of the mega-bridge - June 9, 2004
During the June 17, 2004 monthly meeting of the Society of Professional Engineers Thailand (SPET), John Teggart, Project Quantity Surveyor TNNS Joint Venture (Taisei Corporation), gave a presentation about the Bangkok Industrial Ring Road Project. The photos on this page were taken of the slide show illustrating the project.

From the Society of Professional Engineers, Thailand: In order to relieve the commercial traffic congestion around the industrial areas of Bangkok Port , Poochao Saming Phrai Road and Suksawat Road the King initiated the idea of a ring road system. Part of the system is the subject of the presentation. The logistics and summary detail of carrying out this large project in a city will be laid out including the purchase of land and property, demolition of 881 houses and factories, the re-routing of industrial traffic and river ferry services and constructing high quality bridges and roads through swampy and river flooded areas. The project involves two cable stayed bridges with dimensions, 702m long and 582m long on concrete pylons 172 and 162 m high respectively, there are 3.5 km of approach bridges 0.5km of high level road connecting the bridges and 9.1 km of at-grade road. The world’s largest Movable Scaffolding System (MSS) has been commissioned for the project.

Name of project: Bangkok Industrial Ring Road Project

Earlier plans included a double decker plan and a light rail, but these were dropped.

The idea was to relive the intense traffic that circles the area as well are the non-stop ferry traffic that crosses the Prapradaeng. The south span is higher than the north since ships have to pass under to go to the port.

Also: A map of the route is here (91kb - rescued from the defunct Public Works website).

The project is divided between three contractor groups (represented here as the Northern, Western, and Southern area).

On May 29, 2000 the project was inaugurated by HM The King. Construction started February 18, 2003.

Most workers are Filipinos who worked with the contractor Tonsai on projects in Taiwan.

One of the most difficult problems was clearing the land for construction. Most of the land handed to the contractor by the government still had houses or businesses on it along with people who had no intention of leaving. The government gives 75% of the compensation to the owners holds the remaining 25% until the property is cleared, but many people take the 75% and then refuses to leave, holding out for a better deal. The diagram above shows how the land the handed over as it was expropriated. Each color represents a different period of time when land was handed over.

There was also a 300 year old Muslim cemetery due to be removed. After a resident complained to the Prime Minister in an email, the contractors were forced to change the design for back span supports.

Simulation of what the park under the bridge will look like.

Section detail of one of the four pillars. The piles are 70 meters deep and the structure is designed to take three times the maximum load. The foundations for the main pillars took a continuous 30-hour pour.

The steel for the bridge is imported as steel for this type of construction is not made in Thailand. The first batch had an unexpected 40% tax applied, but subsequent shipments had no tax.

The photo above is blurry, but is useful to contrast with a construction photo taken June 16, 2004. Note the flood relief channel that cuts across Prapradaeng. There is no name for the bridge as yet.
