To be a competent builder, one must have the ability to adapt quickly to manage unusual known or unknown circumstances as they arise throughout the design-build process. This reality is particularly palpable in the business of aquatic construction. Pool and spa builders face many of the same challenges as those who construct homes and commercial buildings, in addition to the various challenges that are specific to the aquatics industry. To provide the owner with quality assurance, pool/spa builders have to make decisive and often radical changes to the equipment on site, labour allotment, labour skill-sets, design components, and special provisions to manage site conditions effectively.
