UPMC East – Hospital Complex Site Development

UPMC East – Hospital Complex Site Development Overview

Monroeville, PA

GAI participated in the design of  a new University of Pittsburgh Medical Center (UPMC) hospital, built on approximately 19 acres of land that was the site of a former hotel and is situated at the southwest corner of State Routes 48 and 22—the second-busiest intersection in the state of Pennsylvania. The hospital complex consists of a 300,000-sf hospital building, comprising inpatient services, medical offices, emergency care, and surgery facilities, along with a 500-car parking garage. GAI prepared a stormwater management system that utilized infiltration, bioremediation swales, and a detention pond to alleviate existing flooding conditions and to satisfy LEED® certification requirements. Other services included conceptual/preliminary engineering; geotechnical boring survey; utility survey and plans; property and topographic surveys; site, grading, and storm drainage plans;  National Pollution Discharge Elimination System (NPDES) permitting; demolition plan and specifications;  Pennsylvania Department of Environmental Protection (PADEP) Sewage Facilities Planning Module; final construction plans and specifications; construction engineering and  monitoring.

The project alleviated existing flooding that occurred on State Route 48 due to uncontrolled site runoff, and the stormwater detention pond was designed to reduce postconstruction stormwater runoff by approximately 50% in the Dirty Camp Run Drainage area. This helped to reduce downstream flooding events along Dirty Camp Run in Monroeville and Pitcairn. The project also included bio-retentions swales, rain gardens, vegetated swales, site infiltration, and a reduction in impervious service area to reduce stormwater runoff and to provide water quality improvements.
