Expansion of Lucile Packard Children’s Hospital
Lucile Packard Children’s Hospital (LPCH) is one of the USA’s most prominent children’s hospitals. It is part of the Stanford University system, located adjacent to the university campus in Palo Alto, California. LPCH was founded in 1991 after a $40 million donation from David and Lucile Packard.
The $3 billion modernization project at Stanford University Medical Center includes a new hospital, the modernization of the original Palo Alto Hospital and new laboratories for the School of Medicine as well as an expansion of LPCH. Within the scope of the project, both new and existing facilities will be designed to comply with the seismic safety design requirements of the State of California. Groundbreaking for LPCH took place in 2012, and construction is scheduled to be completed in 2016.
282 temporary strand anchors and 230 temporary THREADBAR® Anchors were installed
The geotechnical subcontractor Malcolm Drilling built a temporary retaining wall around the existing hospital facilities and adjacent roads. To tie back the wall, DSI USA supplied 282 temporary strand anchors with four to seven strands in lengths of up to 22 m (72 ft). In addition, 230 temporary THREADBAR® Anchors in diameters of 32, 36, 46 and 66 mm were required to stabilize the retaining wall. The THREADBAR® Anchors with ultimate tensile strengths of 1,034 MPa (150 ksi) were 30 m long on average. In addition, DSI USA also supplied the stressing equipment needed for post-tensioning the tendons as well as the coiling equipment to be used on the jobsite. The retaining wall was successfully completed in 2013.
