I think that the engineer should explain to the tract developer that his requirement is absolutely senseless as, I think, most design engineers would agree. Asking not to "overdesign" is however a reasonable think to ask for, so maybe he could just rephrase it. I personally think of Code Minimums & Maximums as legal thresholds below and above wich an engineer might go to jail, and not as standards of good practice. When I was employed in a design firm, I used to always get into arguments with my boss (who had more than 20 years of design experience) because he almost always exceeded the Code minimum requirements. He would say that experience justifies his values, and I would reply that the Code was followed by millions of engineers throughout the world so there was no way that its minimum values were not conservative and amply adequate. So when I started my own work, I experimented with those Code minimums for, for example, shrinkage & temperature steel for walls and slabs (of course I didn't mess with columns and stirrups since we're in a seismic zone.) So I designed a basement wall with minimum horizontal steel (actually slightly above Code minimum) and maximum allowable spacing (actually slightly below max.) So the result was one significant vertical crack at midspan which showed as soon as the forms were striped, and a few months later, when the winter and cold came in, vertical cracks at about 3m spacing started appearing. Of course, I already forgot the $200 dollars I saved in steel reinforcement but I think these cracks will bug me forever. Try for example to specify the maximum allowable vertical steel reinforcement in columns and the contractor will probably send you a hit man :) I could give many examples like that, but I guess the moral of the story is that code minimums & max should be viewed with some skepticism and design experience along with local rules of good practice should always be taken into account.
