Got an interesting call the other day... A large inernational company approached us the other day to design/build a landscape for an existing courtyard/atrium that they have deep inside one of their lab/R+D buildings here locally. Its a pet-project of one of their design teams, and they requested a paver installation along with a half dozen shrubs or so and a few planters. They plan on holding informal meetings there from time to time with two tables and what not around to facilitate that. There is a 30' Japanese Maple that looks like it has held up pretty well through the years in a raised planter that will stay, and some glorious 4-5' Julianne Barberry they want removed (of course!) The initial kicker is going to be removing somewhere around 15 tons of gravel to prepare the area. We have never taken on a job with such limited access. There is a loading dock that one of our trucks will match up to that we can use about 50 yards away with no steps and only a small ramp going in. The one major snag I forsee is that just before we reach the area, there is a narrower 5' hallway. My main questions are: -What are some common pitfalls that any of you may have experienced while working "inside" of a building? -We will be asked to work either at nights and/or on weekends, obviously that raises our labor rates, what other issues such as supplyer availability could I overlook? -They requested sustainable materials be used whenever possible. Has anyone got any products or experiences here? I'm not so worried about this, but I figure if I do find something it would help make this an easier "sell" I am sure to think of more questions but what ideas do you guys have for now?
