The long-term benefit of these material selections will be less maintenance and longer replacement intervals, resulting in reduced costs and associated energy. Environmental considerations were carefully examined with regard to the use of concrete, and particularly fly ash additive. The team carefully reviewed the scientific literature about the health aspects of the latter concluding that fly ash is not an issue in either the short term or the very long term. Fly ash was incorporated primarily in the foundations where color was not an issue. In addition, all of the concrete wood formwork was recycled after use.
