I think Mike Young has a decent point.
Of course, design-bid and design-build and in house construction have all been around forever. Design-bid was prevalent for many years but the trend now in golf is design-build or in house (owner or contractor). The design-build guys have done a better job of convincing the owner that they are the ones getting it done. Of course, that presumes that design isn't that important, that artistry isn't that important, etc.
And, for that low budget public course in Omaha (which almost certainly is a Landscapes Unlimited Design-Build-Own project) it probably isn't. If the $30 customers come out to play, having spent another $200-400K on a gca would not have provided any value. (I do think LU used a cheap, unknow gca for some of the work, but it was probably a limited services contract, btw)
Right now, some (not all) cities are still riding the 90's wave of trying to act more like private enterprize, and not using a low bid process but selecting on qualifications. And there are some advantages to that. At the same time, if the age of more regulation and watchdogging on at least Wall Street by the Feds filters down to lower levels, the design-bid-gca as watchdog process may again become a greater force.
The basics are still in place. If you are building a $7-10Mil public project, do you know you got the lowest possible price if you go design-build? How do you know if the funds are accounted for properly if the spender is also the reporter of spending?
I believe gca's have kind of shot themselves in the foot. For years, we offloaded many services we used to do - irrigation design, greens mix, full time on site reps, etc. in favor of other consultants and full time independent project managers (which some also reasonably favor to keep the reporting separate from the design) We have left control of the projects to others in the name of reducing liability and are now just responsible for the artwork, as it were. As per above, there are many projects where the cost of artwork is deemed too expensive, and we SHOULD be thinking in terms of reduced fees for reduced responsibility and as being part of a team rather than the leader of the team.
And, its hard to be too innovative if you aren't the leader of the pack on a team. Having a builder being the head guy automatically means that construction expediency, budget, etc. are the prime drivers over "pure design" whatever that is. Now, for the top end projects that think they need a signature, the architect led design build also works fine, because those projects have a budget, but if you choose the gca to lead, then design nearly automatically (perhaps within limits) leads the process. At the mid range, I have seen more resistance to architect led design-build. But where its accepted, its a factor of seemingly reducing design fees as part of the process.
Sorry to go a little OT on this one.
