As the title suggests, I am currently working on a project that involves land leveling with high-volume fill soil. A qualified surveying company was hired for an initial survey, and the conclusion was that the foundation category is grade 2 (moderately complex foundation). Based on the engineering importance level, site complexity level, and foundation complexity level, the grade of this geotechnical investigation is comprehensively determined as Grade B. I would like to ask those who are knowledgeable: is it absolutely necessary to hire a company with Class A qualifications in geotechnical engineering design to carry out foundation design? (Note: The design institute has currently indicated that their qualifications are not sufficient; however, I have also consulted with other design institutes with Class A qualifications in chemical engineering fields, and they are able to carry out foundation design based on the preliminary investigation reports and recommendations (such as using pile foundations, dynamic compaction, or composite foundations, etc.).)
The types of projects that a design institute can undertake are determined by the industry (specialty) scope and project scale specified in its design qualification certificate. Class A design institutes specializing in chemical engineering are capable of undertaking large-scale projects in the petrochemical, pharmaceutical, and chemical engineering sectors, including engineering design across various fields such as foundation design, structure, architecture, process engineering, piping, automation control, and electrical systems.
So you think that having our professional Class A qualification from a design institute is sufficient, and there’s no need for a separate geotechnical engineering design qualification, right?
Yes, in theory, design institutes with Class A qualifications in chemical engineering are capable of carrying out geotechnical engineering design for chemical engineering projects.
