1. The consultant should specify the sulfate exposure category (ACI 318) based on
soluble sulfate testing and provide recommendations for sulfate resistant concrete if
necessary.
The structural engineer should design all concrete flatwork and structural concrete to
default to the severe sulfate exposure category (ACI 318) unless corrosion testing is
provided.
2. The consultant should provide the site seismic design category.
The Seismic Design Category is D based on the OSHPD Seismic Design Maps
consistent with Section 1613.3.5 of the 2016 CBC and Section 11.6 of ASCR 7. 10.
If we can be of any further assistance, please do not hesitate to contact our office. This
opportunity to be of service is sincerely appreciated.
Respectfully submitted,
