Helicon Project: Vibro Replacement Stone Columns at Blue Heron Health and Rehabilitation, Wesley Chapel, FL
Client: The Douglas Company
Engineer: Mortensen Engineering, Inc.
Market: Institutional

Project Details:
12 production days
Installation of 394 vibro replacement stone columns, 5,300 linear feet

Technical Details:
The vibro process strengthens soils to allow a variety of structures to be supported on shallow spread footings.

Advantages of Vibro Systems:
Substantial Cost Savings
Fast Installationaggregate piers
Decreases the Risks of Future Soil Issues

The Project: Blue Heron Health & Rehab (The Douglas Company)

The project is a new Health & Rehabilitation facility in the Seven Oaks Community, located in Wesley
Chapel, Pasco County. The structure is approximately 57,600 square‐foot building with associated
roadway, pavement & parking areas. Due to the presence of loose to medium‐dense fine sands to
slightly clayey fine sands in the upper 25 feet, the Geotechnical Engineer of Record recommended a
ground improvement program for Vibro‐Replacement Stone Columns (VSC). In addition, because of the presence of overburden soil erosion/raveling evidence related to possible “sinkhole conditions”, the Geotechnical EOR recommended a Compaction Grouting (CG) program to mitigate the concerns.

Challenges:
The challenges encountered during VSC installation were minimal:
 Limited movement around the site, due to ongoing site conditions
 Weather conditions were unfavorable and slowed production

The Solution:
Helicon followed the Compaction Grout (CG) parameters, provided by the Geotechnical Engineer of
Record, during the installation. Our crew installed (21) grout injection points to approximately 30‐50
feet. Helicon also worked alongside the general contractor & the geotechnical/structural design teams, to develop a cost‐conscious Vibro‐Replacement design submittal. The VSC Program was designed to meet the design load criteria of 6,000 psf allowable. Helicon’s VSC crew worked approx. 10‐hour shifts for up to six days a week, in order to meet the client’s critical path schedule. Efficient planning & coordination was key to overcoming the challenges & limitations. (394) Vibro‐Replacement Stone Columns (VSC) were installed from site grade to depths ranging from 10‐ft to 25‐ft. Helicon collaborated with the Geotechnical Engineer of Record throughout the work and confirm all recommended criteria were followed. The CG & VSC work was successfully completed in just (12) days and finished on‐time and within budget.
