From its very first issue, this magazine has made one key point over and over again: Soil conditions determine the way a watershape’s shell is constructed; to achieve success in construction, the approach must be established by a competent engineer and followed on site. Through the years, numerous contributors to the magazine have described the process of placing watershapes on hillsides or dealing with soil conditions that lead to differential settlement. So far, however, relatively little attention has been paid to the challenges of working in locations where
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
