The same client complaint- the architect cannot deliver his designs at the construction cost he said he could. The old canard that good design pays, is simply that 'good' design is what the Developer's Equation leaves on the table for the architect to use after all other variable are accounted for- 'good' (cheap) external cladding or finish systems, 'good' (cheap) variable volume airconditioning, 'good' (cheap) efficiency ratios squeezing public spaces and creating dark office space...
Developer's Equation- huh? What's that?
Any architect practicing in the United States has to be registered with a local or State Board that certifies his competency. Together with structural engineers, they are defined as 'design professionals' who are the only persons (not firms) certified to make application for building permits and thus to be responsible for the design of buildings subject to the permit.
Fire resistance (both active and passive) are tightly regulated under US buildings codes, and are rigorously applied and monitored. The UK can do worse than to adopt the International Building Code and its various sub-codes, and including the requirement that only properly-certified competent architects act as 'design professionals' defined in Code.
Right now it is statistically way safer to be a high-rise apartment resident in the US than the UK... go figure!
