Hilton Garden Inn, Tustin

This 5-story hotel includes a basement level, indoor pool, outdoor patio seating areas, a covered front lobby entryway and multi-level floor post-tension and framing. GMU performed geotechnical observation and testing during site grading and special inspection and material testing services for all above and below grade construction. Unique challenges to this project included soft, saturated and highly expansive near surface soils and high groundwater. An innovative soil-cement mat was utilized to stabilize the soft subgrade soils under the building footprint and eliminate the need for deep foundations. The hotel foundation system consists of mat-slabs and podium decks.
