About this file
This is a geotechnical core boring report prepared by Tierra South Florida, Inc., for the Broward County Highway Construction and Engineering Division in West Palm Beach, Florida, in support of the Royal Palm Boulevard safety improvements project. The report documents standard penetration testing (SPT) data from two boring locations (MA-1 and MA-2) conducted on June 5, 2024, along Royal Palm Boulevard near the intersection with Blvd near Station 54+69.35 and 54+53.43. The borings were advanced to approximately 16 feet in elevation, revealing soil strata consisting of topsoil, light brown sand with limerock fill, silty sand (SM), limestone (SP) with shell components, light gray shelly sand (SP), and brown sand (SP). SPT N-values ranged from 10 to 40 blows per foot, indicating soil density variations from loose to dense conditions across the two boring locations.
The geotechnical investigation identified soil conditions that require special consideration for construction activities. The report notes that the contractor should anticipate difficult excavation and stabilization conditions, including potential cave-in of loose to very loose sand, compacted fill, and cemented limestone that may offer high resistance to excavation. Bentonite or polymer slurry retention may be necessary in sandy soils at depths below the groundwater table. Environmental classification indicates slightly aggressive conditions for both the substructure and superstructure. Laboratory testing on soil samples collected at depths of 8 to 10 feet and 13.5 to 15 feet provided natural moisture content, fines passing the #200 sieve, and organic content data to support design and construction recommendations for the roadway widening and safety improvements project.
