Pitt Rec Center – Repurposing Existing Features for New Support of Excavation System
Andrew
Moran, P.E.
Nicholson Construction Company
University of Pittsburgh is creating a new Recreation and Wellness Center (Rec Center) on their main campus in Pittsburgh, Pennsylvania. The new construction required the demolition and removal of two existing university structures: the O’Hara Parking Plaza and the Learning Research and Development Center (LRDC). Temporary and permanent support of excavation systems were designed and constructed to reach the foundation level for the new building. Nicholson Construction Company and Mascaro...
Optimization of Pile Foundations Improving Soil Exploration Using CPT
Paulo Oróstegui
OITEC Ltda.
This study examines the impact of advanced geotechnical investigations on foundation design optimization. A case study involving 20-meter-long, 1.5-meter-diameter piles for an overpass foundation above a railway line initially indicated a need for deep foundations due to potential soil liquefaction, as suggested by Standard Penetration Test (SPT) data and a high water table. However, a detailed assessment using Cone Penetration Tests with Pore Pressure Measurement (CPTu)...
Piles and Micropiles with Expander Bodies (EB): Quality, Economy and Time Optimization
Expander Body Technology applied to piles and micro piles significantly increases resistance compared to shafts of the same geometry. This reduces the number of elements, shortens them, or makes them slenderer. In addition, the technology requires continuous pressure and volume recording of each EB, which means that quality control is very high. This presentation will show the results of the Manzana 40 towers, in Santa Cruz, Bolivia. The project was executed with this technology, replacing the...
