JACUSTOMER-o82q54y9- :

sorry under water

walkereng :

A Land Surveyor will establish control points near the project site and he will survey the entire project site to develop topography that the design engineers can use in their design process. He would also establish the line and grade of the actual tunnel construction once it is designed. The control point set by the surveyor will be used by the contractor to build the tunnel in the exact location it was designed to be built.

walkereng :

The civil engineer will design the tunnel to meet it's general purpose and keep the construction cost as low as possible while meeting accepted engineering practice and codes.

JACUSTOMER-o82q54y9- :

And , please if you can , compare three methods of tunneliling and choose the best to be use on this project and explain why you choose this method and reject the others . thanks

walkereng :

The construction manager will usually be on the construction site and keep track of the day to day operations of the project. Make sure the equipment is there to do the job, make sure the sub-contractors are performing well, make sure the project stays on schedule, make sure he monitors the materials and equipment used to the contractors can get paid, etc.

walkereng :

Is that enough information for you?

JACUSTOMER-o82q54y9- :

yes it is .

walkereng :

Tunneling methods are determined based on the type of soil you will be building your tunnel through. Do you know what the soil is like?

walkereng :

Tunnels are dug in types of materials varying from soft clay to hard rock. The method of tunnel construction depends on such factors as the ground conditions, the ground water conditions, the length and diameter of the tunnel drive, the depth of the tunnel, the logistics of supporting the tunnel excavation, the final use and shape of the tunnel and appropriate risk management.

There are three basic types of tunnel construction in common use:

  • Cut and cover tunnels, constructed in a shallow trench and then covered over.
  • Bored tunnels, constructed in situ, without removing the ground above. They are usually of circular or horseshoe cross-section.
  • Immersed tube tunnels, sunk into a body of water and sit on, or are buried just under, its bed.
JACUSTOMER-o82q54y9- :

i dont know yet but it to cross thames river at london , and is a comtaninated soil with infestation of japanise knotweed and same fly-tipping which may contain asbestros.

JACUSTOMER-o82q54y9- :

what the best method that can less enviroment inpact

walkereng :

Can't really pick a tunneling method without knowing exactly what material you will be tunneling through. Contamination of soil would most likely rule out any type of cut and cover.

walkereng :

The immersed tube would probably be the best environmentally

JACUSTOMER-o82q54y9- :

ok , i will do more investigation gyological at the expecific site .

JACUSTOMER-o82q54y9- :

thank and my regads
