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.   $90.00 ea.
Class 5 Mostly common used Low rise commercial Building. Length 30’-0" to 45’-0" 8 tons $150.00 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 $300.00 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 $425.00 ea.
Precast Concrete Utilized on high rise construction When attempting to reach sand strata Between 80’ to 100’ below surface.   $1,800.00 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
