There are a number of due diligence items that should be considered. AEI can help you with two of those items, Environmental and Geotechnical. AEI performs Environmental Site Assessments, sometimes called an ESA or a Phase I, on properties to identify environmental concerns. AEI also performs geotechnical explorations and provides subsurface information for use in estimating site development costs.
The fees will vary depending upon factors such as:
The energy used to compact the soil using a Modified Proctor ASTM D-1557 is approximately 4 ½ times the energy used to compact the soil using a Standard Proctor ASTM D-698.
The result is a material that is 5% to 10% denser or more compact.
The most common type of moisture test is the Rate of Vapor Emission Test, ASTM D-429. A test specimen is adhered to the floor for a minimum of 60 hours. After the test period, final measurements are made and the rate of vapor emission is calculated.
For example, a test started on Friday evening would be completed by Monday morning. You should be aware that prior to testing, the building should be enclosed with the HVAC operating for a minimum of 2 weeks.
Floor Flatness (FF) A dimensionless number that describes the flatness or bumpiness of a random traffic floor.Floor Levelness (FL) A dimensionless number that describes the levelness or tilt of a random traffic floor.ASTM E 1155-96 is the “Standard Test Method for Determining FF Floor Flatness and FL Floor Levelness Numbers”. AEI is equipped with a “Dip Stick” which measures these values and provides instantaneous output in the field.
