Commercial projects are typically more intricate than residential projects, and rightly so. Most commercial projects are intended for "unattended operation." They will use components and construction methods appropriate for long-term service.
For your fountain and water feature to "make a statement," you will want to locate it where it can be seen. But, for it to be enjoyed by the public, you must consider their interaction and attention with your project.
Design and installation planning runs the range from private corporate parks at one end to shopping malls at the other. We have had a lot of exposure to different needs and can make consulting with us time well spent.
A commercial project generally will have a fill line, drain line, and at least one electrical conduit. These must be brought in from existing utilities and sized appropriately. The cost of laying a few spare wires now is a fraction of the cost of retrofitting a project later on. Be sure that equipment is properly sized and selected. We regularly save our customers thousands of dollars each year in operating costs through modern and conscientious design.
This typically require only a level compacted sub-grade. Interlocking landscape blocks may then be used as shown without special consideration. Concrete pools or masonry walls, however, will likely require the expense of concrete footings below frost line for uniform support.
The ability of fiberglass pools to remain filled in winter is an important benefit to year-round beauty.
Most water features do not require special water treatment. There are however several classes of fountains (curtain fountains, water walls, laminar nozzles) where water conditioning and filtering is critical.
Finally, Make sure that the end product you are getting comes properly documented. Just because it looks official, a stack of component cut sheets now will not later warm the heart of a new facilities manager five years from now.
