DESCRIPTION OF STRUCTURAL SYSTEM
This project consists of a reinforced concrete below-grade swimming pool. This package includes
structural calculations providing the required reinforcing steel for the radius walls of the pool for varying
radii. These structural c• •. . - .-• • •_ -. • compliment drawings provided by others.
This design is done with 2,500 psi concrete to avoid the need for concrete special inspection, though
oncrete to be used is specified at 3,000 psi. This design is done based on 60 ksi reinforcin•
Due to the specified hydrostatic relief valve, no provisions or •uoyancy ave been incorporated.
This design is based on a flat site, assumed geotechnical design criteria, code prescribed minimum
properties, and without the use of a geotechnical investigation. The client and owner have declined to
obtain a geotechnical investigation and by doing so, have accepted all liability for soil related design
issues. It is the responsibility of the pool contractor to notify VLMK Engineering + Design if the pool is not
being constructed on a flat site.
***LIMITATIONS***
VLMK Engineering + Design was retained in a limited capacity for this project. The design is based upon
information provided by the client, who is solely responsible for the accuracy of the information. No
responsibility and/or liability is assumed by, nor is any to be assigned to, VLMK Engineering + Design
for items beyond that shown in this Structural Calculation Package.
