Can anyone offer advice on this new layout?

Hi everyone.. This layout is something I have never had to do before, most places around here are square, or the odd curved parking here and there, but I have never had the opportunity to do curved tandem on a new layout. The far back row I will assume using the "swing arc" method for concave parking, but can anyone offer any advice for the concave tandem stalls in the middle? I haven't seen this place yet, and the drawing looks a little screwy to me (directional arrows over parking stalls beside an island? what the (expletive) is that? I assume the flow of traffic arrows shouldn't be there). My idea is to measure the wide end and divide for stalls, then measure the narrower side and divide for stalls, using the far back curb to mark out an arc line for the tops, centre lines, and bottoms? This seems like it would work, however anyone with advice on this would be appreciated

It may be the same just different wording but I would measure the narrow side of the stall and divide for stalls then measure the wide end of the stalls and divde by the number of stalls at the narrow end to determine the width of the wide ends.

Can you make the drawing larger hard to see

All those numbers mean something, you'll have to look through the plans or punch list to find out, this may be a plan for what is there now and notes for changes. The arrows for the two way may not get painted, I would ask first, but the one way should be painted or some idiot will go the wrong way. Lay out is simple, measure the small end and triangulate the big end, the lines in the central area on the big end will get farther apart. Just find out what those numbers mean before you start, could be the location for patches and other work and it looks like they intend to make a drive way in that double row so the lazy people don't have to drive so far to the exit.

You have it right. Here in the mountains most every lot has a concave or convex area. If you happen to have a auto layout machine that is where they really shine. Looking at the drawing it appears the left end transitions to less or no concave than the right end. Hard to really see as drawing is so small. If that is so I would lay it out in several sections so that the line widths transitioned more smoothly with the curb arc. A construction calculator also works well using the run- rise and diagonal buttons and marking arcs.

Sorry guys, the forum auto resizes the link to the pic i posted. If you click on it, the larger version will show. Thx for the advice so far.

My guess on those arrows on top of the parking stalls is that is a temporary road as the stalls on the left are marked future parking. The stalls the arrows are over would probally not be put in at this time and would be a road until after the future parking is completed with the road is extended. Your plan to measure both ends and divide out for the stall widths should work well. The hardest part to make look good will be the center banks with head in parking.

Talk to your Grading/Paving Contractor and his surveyor or layout man. Many times for a very small fee they will hit all the control points for a precise paint job. Those points for the parking lot are already in place for this drawing of the school, should be simple. Keeps them involved and the GC happy with final product. Also shares responsibility.
