Is there really a purpose to specifying how my architectural woodwork project is installed?
You bet. The best way to insure a good job is to insist that the shop that built the furniture, fixtures or materials is the shop that installs it. Less-qualified contractors will give you reason upon reason why any of their guys can do the installation, but if theres a problem with the finished job, who gets to fix it? The fabricator will say its the installers fault and vice versa. Just remember: its less expensive to have it done right to begin with than it is to have to re-do it because the first guy screwed it up. Thats the virtue of single source accountability and responsibility, and the best way to insure this is to write it into your specs.
