CJC&A's geotechnical pedigree is directed by our company's founder, Dr. Carl J. Costantino, Professor Emeritus of geotechnical engineering at the City College of New York.  Our geotechnical services include:

​

• Design of shallow and deep foundations,

• Support of excavation designs

• Soil dynamics,

• Liquefaction assessment,

• Settlement analysis, as well as

• Most geotechnical related issues.

​

The CJC&A team specializes in solving advanced engineering problems, including,

​

• Soil-structure interaction analysis

• Non-linear and linear structural analysis

• Seismic fragilities

• Seismic margins assessment

• Structural dynamics (impact, NPH, etc.)

• Seismic detailing and retrofitting

CJC&A has been providing analysis and consulting services to support of safety basis evaluations of nuclear facilities for many years.  We maintain a quality assurance program compliant with,

​

• ASME NQA-1a-2009, including subpart 2.7 for software development

• 10 CFR 21

• DOE Order 414.1D

At CJC&A, we develop and maintain high performance computing programs to solve large-scale engineering problems, including SDE-SASSI v2.1, our propriety version of SASSI capable of solving today's largest SSI problems.  SDE-SASSI was the code of record used in the U.S. DOE SASSI Validation and Verification Project, in which CJC&A was the Implementer Team for the multi-year effort fund by DOE and several national laboratories.
