Group Delta Consultants has provided geotechnical recommendations for the design and construction of numerous parking structures throughout Southern California. Our clients have included City/County/State agencies, Academic/Medical institutions, and private developers. We are experienced with design issues of multilevel parking structures as well as subterranean structures.
Two parking structures at the Garfield Entertainment Center in Alhambra
Each parking structure is a 5-story building without a basement
Footprint of the structures range from 22,000 to 80,000 square feet, with maximum column loads ranging between 600 and 1200 kips
Group Delta's Role:
Design Level Geotechnical Investigation
Laboratory sampling and testing to characterize the soils and evaluate engineering properties
Provided economical spread footing recommendations with some removal and recompaction of near-surface loose soils, thus avoiding piles foundations
Structures are supported on shallow spread footings
Completed both projects on time and within budget
USC Exposition Park Parking Structure
Project Description:
The four-level parking structure is adjacent to the USC campus located in Los Angeles and the property is owned by the State of California.
The structure sits in an excavation that extends about 34 feet below the existing grade.
The slopes of the excavation are landscaped, so that it exposes most of the perimeter of the open parking structure.
One side of the structure required a permanent tied-back wall or a soil nail wall.
Group Delta's Role:
Design level Geotechnical Investigation
Laboratory sampling and testing to characterize the soils and evaluate engineering properties
The structure, which imposes column loads of up to 1 million pounds, was designed for support on conventional spread footings established in a dense sand and gravel
Accomplished the excavation required with the use of shoring and tie-back anchors
West Los Angeles Community College
Parking Structure
Project Description:
Four level reinforced parking structure on the campus of the college. The structure is 400 feet by 188 feet in plan and has column loads up to 650 kips.
Group Delta's Role:
Design Level Geotechnical Investigation
Geologic Seismic Hazard Evaluation
Geologic Seismic Hazard Evaluation
DSA Level Construction Services
Harbor College Parking Structures
Project Description:
New concrete parking structures ares planned at the north and south parking lots
Preliminary concepts are to construct two to three level concrete parking structures with or without one level of subterranean parking
