Typically, an “Independent Design Check” involves the following activities:
Complete review of bridge planning and assessments. Re-analysis using other methodologies is warranted for critical design components.
Complete re-analysis of all aspects of the original structural design, preferably (but not essentially) by a methodology other than that used in the original design.
Ensuring that the engineering drawings accurately convey the design philosophies of the original design and the checkers design.
Ensuring the completeness, integrity, and accuracy of all aspects of the engineering drawings.
To resolve issues of concern, an independent check of a specific component of the structure may be requested by the client at any time throughout the design process.
