Lakeview Commerce Center – Building III
Owner: Panattoni Development Company
Client: Brinkmann Constructors
Location: Edwardsville, Illinois
Services: Construction materials testing, special inspections
Scope of services: The project consisted of a new single-story 400,000 square foot tilt-up concrete panel warehouse. The building was designed to be founded on shallow column and continuous foundations with a slab-on-grade. Site improvements consisted of an asphalt-surfaced and concrete-surfaced parking lot, drive lanes, and roadways. Geotechnology provided construction materials testing for soil, aggregate, concrete, hot-mix asphalt, floor flatness and levelness, shallow foundations, reinforcing steel, and structural steel.
Problem: The project site consisted of potentially expansive, high plasticity clay soils.
Solution: Instead of removing and replacing the unsuitable soil with a low plasticity soil, the owner elected to treat the existing soil with code-L, a by-product of the lime manufacturing process. Code-L is blended with the soil at predetermined percentages causing a change in the soil’s chemical and physical properties. This reaction changes the soil plasticity and subsequently reduces the swelling potential.
Benefit: By adding code-L to reduce the plasticity of the soil, there is a reduced risk of the soil swelling, which could lead to damaged foundations costing the owner money. Additional benefi ts include increased soil strength and reduced moisture content.
