Symphony Park B & L

GES provided QAA services for the City of Las Vegas for two new parking garages located at parcels B and L within Symphony Park. The combined scope of these two projects includes 450,000 square feet of parking spaces, and over 50,000 square feet of retail, office, storage, and mechanical rooms. The project consisted of the construction of two 520-space concrete parking garage structures each with an at-grade level with 4 raised levels. The garages are supported on isolated footings and slab-on-grade. Each of the raised levels are comprised of precast concrete structural members and were topped by a cast-in-place concrete slab. Masonry walls enclose the elevators, storage rooms, and mechanical and electrical rooms. The at-grade levels include both concrete and asphalt concrete pavements in the driveway and parking areas and associated site improvements.

GES’ scope of services included providing qualified personnel performing a long list of tasks including:

•    General construction observation during the earthwork for structural areas to evaluate the suitability of soil materials and perform density and moisture testing
•   Laboratory testing of native and imported soils to evaluate the soil materials conformance to the requirements of the geotechnical reports
• Observations of reinforcing steel placement prior to concrete placement along with the sampling, testing and continuous observation during placement of structural cast-in-place concrete
• Observations of reinforcing steel placement prior to grout placement, and to perform periodic testing of samples and observation during placement of grout for masonry walls
• Recurring observations of spray applied fire-resistive materials
• Regular observation during installation of post installed anchors or dowels in concrete
• Provide qualified field personnel to perform periodic observation of structural steel placement, high strength bolting, and welding, and NDT
• Observation and testing during non-structural site improvements, such as on-site utilities installation, curb and gutters, valley gutters, sidewalks, and asphalt paved areas
• Density and moisture testing for the utility trench backfill within the garage envelopes and during the aggregate base material placement for the slabs-on-grade. 
• Creation of a final report for each garage summarizing our observations and material testing findings for the approval of both the client and building department
