In the course of my watershaping career, I've come to divide remodeling projects into two distinct categories. The first is what I call cosmetic refurbishing. Here, all a homeowner usually wants is a superficial updating of a pool's or spa's appearance or performance through application of a new interior finish, some fresh waterline tile, maybe new coping and decking and, often, new equipment or perhaps a poolside waterfeature. I avoid these projects as energetically as possible because, typically, the challenges are thin and there's little room for creativity. The second category encompasses what I call

There's no room for guesswork when it comes to structural engineering, says Ron Lacher of Pool Engineering, Inc., and that's especially true when it comes to concrete structures designed to contain water. Here, he opens a series on structural fundamentals related to watershapes by defining the need for precise structural planning and careful attention to workmanship - the keys, he says, to achieving a project's aesthetic and functional goals. Despite the apparent intricacy of any good set of engineering drawings and contrary to what many people think, structural plans for concrete watershapes are pretty cut and dried. At the most basic level, the art and science of structural engineering deals with predictable forces placed upon structures and with the construction techniques and materials required to counteract those forces. The basic mathematic calculations are straightforward stuff, and everything runs in accordance with building codes that
Now comes the fun part. The final stage of building a stream is where all of the planning and close attention to the stream's earthen substructure, transitions in elevation, liner alignment and hydraulics come into play as you move to build in details that effectively mimic nature. In the first two installments of this series (click here for part 1, here for part 2), I discussed in detail how you excavate and grade the site, place the major transition stones, lay in the liner and install
