I'm looking at plans prepared by a landscape architect for a commercial property about to be built. A good friend will be the builder and he wants me to do the installation. I've done some pretty big residential installs but nothing commercial with drawn out plans. First question: How precise does the installation have to be compared to the plans? Example: Where they've drawn 80 hollys two wide, do they expect all 80 spaced exactly like the drawing or 80 hollys proportionately spaced and planted? In other words: very similar to the drawing but not precisely. Second question: Simliar to the first question, they have some of these hollys directly under some trees to be planted. In the drawing, they go right up to the trunk. Do they really want this? The plans call for 80 hollys and that's what they have drawn, but that seems like poor placement. Third question: In the areas of grass seeding, do I really need to plant (and prove) the type of seed it calls for? Not very wise choices in my experience, but then again: that's what the plans say. I guess if I had to sum all this up; if this install looks just like it's drawn (to the naked eye), is that what they expect? Or will they come out with rulers and protractors making sure I didn't go "off plan"? Would love to hear from those of you who've done this and your experiences. As always, thanks for everyone's help.
