Charlie,
Since the contest should reflect real life, I don't see any need for the contestants' entries to be kept confidential.. I assume a thought to reduce judging bias.. in fact I'd expect that 8 proposals for a gca job would not be uncommon and that a short list would be established for further debate, study, and questioning/defense of submitter proposals before a final selection is made, for whatever reasons the developer can or must live with..
so here's some of my recollection of time spent for this effort..
time spent on the computer, downloading files, using Charlie's tutorials, playing with Sketchup.. ~4 hrs
time to decide to not use Sketchup until a full design was crafted on topo, .. about two double JD's on the rocks.. and a quick nap after a morning 18 one fine winter's day in SE TX..
time spent printing out copies of the topo.. minutes
time drawing readable numbers/tags and coloring on topo elevations.. ~30 minutes
time spent in armchair studying topo, looking for green sites, at land slopes, and distances with a compass and ruler, ~ 2-3 hrs one night watching tv
time for making first routing, 27 holes ~ 2-3 hours on another night, could a play be made over the clubhouse?
time to decide on 2nd routing, 18 holes ~ 1 hour or so at work, hmmm, only a strong bold shot from the range..
time saving topo jpg to pdf format, minutes
time placing routing on topo and double checking using Adobe Acrobat drawing and measuring tools, 1-2 hrs
time to draft narrative descriptions, ~ 3 hrs to play in mind
edits/tweeks to make 3rd routing, ~ < hr, but several times
time to think about and make layer with bunker location marks ~ 2 hrs
time to think about & draft green shapes and slopes ~ 3 hrs
time to integrate bunkers onto routing, ~ hr (details would be field fit with test shots from pro..)
time to sketch greens, ~ hr (details would be field fit to the archi-supt-shaper's eye)
time to create card data and format, ~2 hrs
time to package e-files, decide to hit send button ~ hr
So FBD.. the others are not pathetic, just not quite energetic or obsessive or creatively driven enough to get to the finish line.. and submit something.
for better or worse i did not use sketchup.. a tag team approach like Sean thought of would be nice.. like at work.. "I have people for that task " . and then there'd be a couple of more hours for kickin the tires some more with new views..
