This stage of the project built strong team dynamics and trust that positioned us to work through the challenges of a complex construction project. The construction schedule was particularly interesting because the elephants were to remain on view throughout, which required safe and secure areas while the other sections of the new yard were being built. Every day counted as we choreographed a ballet of large animals moving between enclosures. Shotcrete as a method of construction contributed to schedule enhancement in multiple ways. As an example, the conventional concrete construction of the deepest life support vault of the project’s pool would have required closing the main access road to the site. However, using temporary shotcrete walls constructed with top-down soil nail techniques kept this from occurring, saving weeks on the overall schedule. Animal management staff worked closely with the construction team to develop the phasing strategy and reported that the changes in location kept the elephants mentally and physically active while they were moved between spaces. Construction also kept us mentally and physically active while we deployed plans and methods that used the full range of shotcrete’s versatility. On this site, we built tall, architecturally finished walls that provided containment for the elephants (this required that the walls were at least 9 ft 3 m tall with an overhang). These were textured with embedded roots and real cobbles to simulate the aesthetic Fig. 3: Three-dimensional samples displaying the different textures were prepared for approval prior to production Fig. 4: Shotcrete finishing for bedrock textures of eroding embankments in Asia. To make them as authentic in appearance as possible we searched for images from Asia so we could replicate specific features of the land. We manipulated our textures to display the stratigraphy of the soil lens, replicating various soil types, including clays and sandy loam. We stained the surface of integrally colored shotcrete to replicate the rich colors of Asian soils. In some areas, we purposefully showed the dynamic process of www.shotcrete.org Winter 2017 | Shotcrete 19
