To accommodate the construction of the new facility, the site required a series of SRWs (segmental retaining walls) to be installed, creating some level terraced areas to accommodate parking and traffic flow. The wall also needed to be constructed quickly to avoid possible collapse of the excavation before completion of the wall. Budget was also a key consideration. The Siena Stone Segmental Retaining Wall System was deemed to be the best system to accomplish these objectives because
