Re: Piles – Cristelle Cay, St. Lucie County, Florida
Dear David,
Pursuant to our correspondence and discussions this letter is to confirm my opinions in regard to the as
built pile capacities at the above referenced project.
My opinions are based upon the following documents:
• Pile inspection report from KSM Engineering and Testing dated November 1, 2021.
• Pile integrity testing report by Applied Foundation Testing dated October 6, 2021
• Thom-Katt grout pump information from Putzmeister
• Letter dated November 10, 2021, from Atlas Piles
• Site photographs showing excess grout (concrete) at pile tops
Based upon my review of the documents listed it is my opinion the pile capacities shown on sheets 9S1.1
and 12S1.1 (50 ton vertical, 2 ton lateral, 20 ton uplift) have been achieved by the pile installation.
Please contact me at your convenience should you have any questions or if I may be of further assistance.
Sincerely,
Brian Stirling, PE
