Question

I need help finding a cost range for the following ground improvement techniques

1 Dynamic Compaction

2 Vibro Compaction

3 Low Mobility Grouting

4 Vertical Drains

5 Vibro Replacement Stone Columns (top feed and bottom feed method)

6 Vibro concrete columns

7 Soil nailing

8 Micropiles

9 Soil fracture grouting

10 Permeation grouting

11 Jet Grouting (single fluid, double fluid and triple fluid)

12 Deep soil mixing (wet and dry deep soil mixing)

13 Vacuum consolidation

14 Ground freezing (brine and liquid nitrogen)

I just need a range for example low 300K to mid 700K per square foot or something similar for each item listed. Thanks   

Explanation / Answer

1.dyanamic compaction

low unit price upto 200k dollars

high unit price upto 400k dollars

these are the cost prices for mobilisation , deep dyananmic compaction, materials for back filling and levelling craters

vibro compaction

vibro compaction does niot need any high range equipment is used in dyanamic compaction

but contionous electric power supply is needed and there is a need vibrating machinery

hence cost is lower when compared to dyanamic compaction

cost range is around 300k dollars per square foot for high range

3. low mobility grouting

Low mobility grouting is defined as material that is injected as a fluid, but does not permeate or travel far from the point of injection. This method is used to compact low density soil (Compaction Grouting), fill voids, seal openings, and to create structural shapes .

this is method requires grouting machines to injection

this may depend upon number of void . hence it has low range of cost for low voids

high range of cost for higher voids

4.vertical drains

Vertical drainage. Prefabricated vertical drains, also known as wick drains, are one of the most commonly used techniques to make soft compressible subsoil with a low bearing capacity constructible. Vertical drainage together with a surcharge reduces the time of settlement substantially.

this method is of very costly , and needs so much of experience and machine

hence it has an cost range around 700k dollars
