02200 Sitework: Southern
Louisiana soil conditions are unique to other areas of the country
and even to other parts of Louisiana. This lower portion of the
Mississippi Delta consists of Alluvial soil technical description.
These soils are unsuitable to maintaining any bearing capability
from a design stand point.
Sites are filled with "pumped river sand" to the desired
elevation to achieve building slab elevations to meet federal mandated
floor elevations. Pump sand – Unit cost delivered $4.50 to
$6.00 per cubic yard.
Pile Foundations: The sub soil conditions described in sitework
section demands that 95% of all building construction require pile
supported structures. The following is a table of pile types and
unit cost.
| Pile Type |
Description |
Max Capacity |
Allowable
Unit Cost |
| Class 9 |
Treated pile
varying in Length 25’-0" to 40’-0".
Normally utilized in Residential construction Mainly driveways
and sidewalks. |
|
$90 ea. |
| Class 5 |
Mostly common used Low rise
commercial Building. Length 30’-0" to 45’-0"
|
8 tons |
$150 ea. |
| Class B |
Another more commonly Used
for commercial Buildings. When the Vertical elements become
Greater(multi-levels above 2 story) or when subsoil conditions
are extremely poor.
Length 40’-0" to 55’-0" |
25 tons |
$300 ea |
| Composite Pile |
Consist of a lower untreated
Approx. 45’- 50’ and an upper Steel can filled
with concrete of approx. 8’-0" to 25’-0 |
30 tons |
$425 ea. |
| Precast Concrete |
Utilized on high rise construction
When attempting to reach sand strata Between 80’ to 100’
below surface. |
|
$1,800 ea. |
All of these piles, with the exception of concrete, develop their
resistance capacity from friction. Therefore, all building regulatory
agencies require a "pile load test" to substantiate the
assumed design capacity. These agencies will waiver this load test
if another test data report produced within a 300 yard perimeter
can be obtained.
Load Test Class 5 / Class 5 / Composite $8,000
Load Test Precast Pile $20,000 |
