Multistrand Anchors secure new building area

San Juan Capistrano is one of the oldest settlements in California. Despite its central position between the modern cities of San Diego and Los Angeles, San Juan Capistrano has kept its historic charm. In addition, the 35,000 inhabitants appreciate the high quality of life in the city, which is enhanced by a diversity of cultural events and many opportunities for various sport and leisure-time activities. Furthermore, the metropolitan cities to the north and to the south can be quickly reached via interstate highway 5 located nearby.

A 1.4 mio. m2 site was designated in the urban area of San Juan Capistrano west of La Pata for the development of a new residential area designed to include 175 housing units and various leisure-time facilities as well as a new high school. The many green areas with hiking paths, playing and sporting grounds which are to be created will provide substantial opportunities for recreation.

The new development area called Whispering Hills received its name from the scenic coast section of Orange County with its gently sloping hills. To permit construction on the site, an existing slope had to be elaborately stabilized.

Stabilization of the slope required the construction of a comprehensive grade beam system in the designated area. The grade beams were tied back with a total of 492 DYWIDAG Double-Corrosion Protected Multistrand Anchors that had to be installed within a very tight schedule. To this end, DSI Long Beach fabricated a total of 305,000 m into 11 and 12 strand anchors with individual anchor lengths of up to 87.5 m.

For the installation work, DSI also supplied prestressing jacks and the "EZ Chair", a new development by DSI America. The "Easy (EZ) Chair" optimizes the fast and safe installation of DYWIDAG Multistrand Anchors.
