Consulting engineers have greater freedom with wider areas of responsible decision making compared to salaried engineers.

This creates special difficulties for consulting engineers.

In ‘design-only’ projects,  consultants  do  not  have  any role  in the  construction  or implementation as per the design specs.

Ideally,  only  the  designer  would  really  know  the  areas  of  difficulty  in execution.

Even when changes in design are required during execution,  the consultant may not be around to effect the changes Client may not have capable people for inspection of the work based on the consultant’s design.

Does the consultant have a moral responsibility to follow through the design in execution?

In any case, job safety is one prime responsibility of the consultant engineer
