Symphony Park – Aspen Heights Projects

Symphony Park – Aspen Heights Projects

Symphony Park is located on the historic Union Pacific Railroad Yard (UPRR). For approximately 90 years, the UPRR operated its maintenance and fueling at this location, causing contamination of the soil and groundwater to the UPRR site and downtown Las Vegas from a variety of contaminants. This Phase I ESA included an extensive file review of records through the Nevada Division of Environmental Protection (NDEP) and of the Soil and Groundwater Management documents created for the Symphony Park location. 

The Aspen Heights project area was determined to be historically located in the area of the former maintenance yard with a fuel pipeline shown in maps to travel through the project area, along the tracks. The current usage of the site was a parking lot for the Smith Center for the Performing Arts. A Recognized Environmental Condition (REC) was determined in the Phase I ESA for the known historic contamination of the site.

Putnam Edge High School

Putnam Edge High School

UES was contracted by Synergy Construction to perform limited asbestos sampling of materials scheduled to be disturbed by on-going renovations to the Putnam Edge High School building in Palatka, Florida. UES performed asbestos consulting services on a “Rush” basis to meet the contractor’s scheduling needs and to assist in the opening of the school for the fall session. UES mobilized an Asbestos Hazard Emergency Response Act (AHERA) certified asbestos inspector to the site, obtained the appropriate suspect samples for laboratory analysis, and delivered the samples to the laboratory the same day.

The laboratory completed the analysis of suspect samples by Polarized Light Microscopy (PLM) on a rush three-hour turnaround time frame. The laboratory results were provided to the general contractor on-site the same day and construction decisions were able to be made in order to complete the project and open the school as scheduled. UES’ quick response to our client’s needs made this project a success.

Spartan Electronics Waste Water Treatment Plant Monitoring Well Install

Spartan Electronics Waste Water Treatment Plant Monitoring Well Install

UES was retained by Engineering Solutions International to conduct a subsurface study at a manufacturing facility in eastern Florida. The services provided were in conjunction with the installation of a new wastewater treatment plant (WWTP) for the facility. The scope of the project was to determine a groundwater flow direction beneath the subject property and installation of a permanent groundwater monitoring system. UES approached the project in two phases.

The first phase of the project included the installation of three groundwater piezometers in a triangular fashion around the WWTP in order to collect groundwater elevation data. Once completed, the groundwater elevation data was used to calculate the groundwater flow direction beneath the subject property. Phase Two of the project included the installation of a permanent monitoring well in the downgradient groundwater flow direction of the WWTP.

The permanent monitoring well will be used for future groundwater sampling events to evaluate the operation of the WWTP. UES employed our internal Sonic drilling equipment for this project in order to obtain a complete understanding of the subsurface geology and groundwater table beneath the subject property and to accurately place the piezometer and permanent monitoring well locations based upon site-specific characteristics.

On May 3, 2017, UES issued a Phase I Environmental Site Assessment (ESA) in compliance with ASTM E1527-13 for the subject property. The Phase I ESA site reconnaissance indicated the presence of numerous abandoned drums and containers, as well as evidence of agricultural pesticide use.

UES Recommended a Phase II ESA. On May 30, 2017, UES conducted a Phase II ESA at the subject property based on the observations noted in the Phase I ESA. Based on the findings, arsenic was identified at a concentration exceeding the Soil Cleanup Target Level (SCTL) for residential use properties set forth in Chapter 62-777, Florida Administrative Code, at the location of a greenhouse and a shed present on the central portion of the subject property.

Based on the Phase II ESA results, UES recommended that the unsuitable soil be removed and properly disposed of in accordance with State mandates. In October 2017, UES provided turn-key source removal remediation services. UES personnel demolished buildings, removed trees, and cleared obstacles for the excavation. UES excavated, loaded, transported, and properly disposed of 800 tons of unsuitable soil detected in the Phase II process.

Gaylord Pacific Resort and Convention Center

Gaylord Pacific Resort and Convention Center

The luxury Gaylord Chula Vista Resort & Convention Center is the centerpiece of the Chula Vista Bayfront Master Plan, a decade-long joint planning effort by the Port of San Diego, the City of Chula Vista, and a coalition of stakeholders. The project will create a premier meeting, convention, and luxury resort with a 22-story hotel tower showcasing 1,600 hotel rooms, including 89 suites with views of San Diego Bay. Amenities will feature a spa, recreational facilities, a pool with a lazy river, and bike and boat rentals. The convention center is state-of-the-art and will contain flexible indoor and outdoor event space, restaurants and lounges, meeting rooms, an elevated ballroom, and the largest exhibit hall in California.

The construction of the 240-foot hotel tower is cast-in-place concrete. Concrete shear wall cores with coupled walls resist high seismic loads in the San Diego area. While the width of the building is only 70 feet, the length is over 700 feet long. The tower also articulates in plan with several 45-degree turns, posing a significant challenge for a post-tensioned slab design. The designs use a combination of shear wall blades and closure pours to ensure an efficient slab thickness. The Conference Center and Exhibit Hall will be steel structures and utilize Buckling Restraint Brace frames for seismic resistance. These braced frames consist of a steel core wrapped in concrete and then covered by another layer of steel.

UES recently performed the updated geotechnical investigation, the updated Phase 1 Environmental Report, the Environmental Soil Management Plan, and the Hazardous Materials Evaluation of the remaining buildings to be demolished. Our team currently provides all onsite geotechnical, environmental, and materials testing and special inspection services during construction. The project will consist of more than 50,000 cubic yards of grading, surcharged building pads, and 1,700 Auger Cast Pile foundations.
