Michael,
Pretty much the same. We get 80% of our fee for plans, 5% for bidding and 20% for site inspections and CA, which seems a bit back loaded compared to engineers, but then, we spend more field time in golf design and construction. We also get paid monthly in proportion to work done, with 10% up front, 10% for concepts, 20% for Design Development (70% completed CD) and 40% for Construction Dox.
There are other consultants required for the EIA, wetlands survey, etc. as well as surveyors to stake property and golf centerlines for the contractor. Engineers are usually on the team for flood studies, comp storage calcs, soil testing, bridge and footing designs, etc.
Most of us now hire out irrigation design and staking and require some supplier design - notably pump stations and bridges.
I personally do all my own drainage plans, except when they tie into housing and flood control projects, and an engineer has to handle those, usually by law.
where possible, most gca's try to stay out of those other contracts, but sometimes, some or all are lumped into our agreement with the owner and we then "manage" the design team. Whether we get paid to manage it is another story.....
The contractor is usually under a separate contract to the owner, and not under the gca. However, many gca's require their own shapers to be "nominated" or required personell of sub contractors to the general golf course contractor. And, some projects do get built on a design build basis, where the large general, like Landscapes Unlimited hires the gca. More common now, but still not standard.
