Commodity or Service Required (commodity class and group, manufacturer, model, and description, as appropriate): 11111500, 22101900, 41113900

Requestor (division, bureau, office, individual, as appropriate): Brandi Bertram

Performance and/or Design Requirements (intended use, function or application, compatibility etc.

requirements; reference to policy, rule, statute or other act of the Legislature, etc., as appropriate):

The State Materials Office currently performs direct shear testing for materials used in the design of Mechanically Stabilized Earthen Walls (MSE Walls). The test is performed in accordance with the AASHTO and FM T-236 test methodology for soil materials. The test method requires the maximum size of the soil particles be such that the test chamber is no less than six times the maximum particle size. For the device the lab currently uses, the maximum size particle of soil able to be tested is 2.24mm. Construction allows for the use of larger particle sizes (up to 2 inches) for soil materials. In many areas of Florida, including South Florida, Limerock materials may have a significant portion (over 50%) over this particle size, requiring the test be performed on materials that do not fully constitute the full scope of material gradation used onsite and provide an ultra-conservative friction angle result. By purchasing this device, the laboratory will be able to test significantly larger particles which would be more representative of materials used in the construction of the MSE Walls. A study performed by FHWA found that testing larger particle sizes increased the friction angles by 5-6 degrees. Implementing this equipment would allow for the use of materials in MSE walls that would have failed testing at smaller particle sizes to pass with larger particle sizes (increasing the availability of backfill materials for construction). Further, if the design friction angle were increased, it would decrease the length of the geosynthetic straps used in the MSE wall construction therefore providing a cost-savings to the project.

Intended source (vendor, contractor): Gilson Company, Inc.

Price: $46,000

Justification for single source acquisition (what is necessary and unique about the product, service or source;

steps taken to confirm unavailability of competition, as appropriate): This device is manufactured and sold by the Gilson Company. There are no available alternatives to this device
