PopStroke

PopStroke

PopStroke is a mini golf entertainment venue that typically features two 18-hole putting courses. UES provided geotechnical engineering and pavement design recommendations for the new PopStroke facility located on a 3.4-acre site in San Antonio, Texas. The new facility includes a wood framed single story restaurant building totaling 10,900 square feet, golf putting spaces, and associated driveway areas. 

UES’ team drilled seven borings in the building, paving, and putting areas and provided recommendations for paving and better drainage for the project.

Mohave Sunrise Solar Phase II

Mohave sunrise solar phase II

The Mohave Sunrise Solar Phase II project sits on the northern third, about 80 acres of a single parcel totaling approximately 220 acres developed with a photovoltaic electric generation facility. 

UES provided information and geotechnical engineering recommendations relative to subsurface soil conditions, general geology of the area, foundation design and construction, retaining wall design and construction, floor slab design and construction, pavement design and construction, and earthwork. 

The scope of UES’s services for this project included a subsurface exploration program. The subsurface exploration program consisted of drilling twelve borings to approximately 20 feet below existing site grades.

CityArchRiver – St. Louis Arch Grounds

CityArchRiver - St. Louis Arch Grounds

In 2011, Geotechnology, a UES Company, was enlisted to conduct a comprehensive geotechnical desk study and Phase I Environmental Site Assessment (ESA) for the JNEM (Jefferson National Expansion Memorial) grounds redesign project. Originally tasked with foundational assessments, Geotechnology’s role swiftly evolved to encompass a wide array of critical tasks crucial to the project’s success.

The scope of Geotechnology’s involvement expanded to include:

  1. Initial Geotechnical Exploration: Conducted extensive explorations, including operations within national park service grounds, soil nutrient sampling, and air vacuum extraction to locate utilities.
  2. Detailed Design and Specifications: Developed meticulous design plans and specifications for reinforced soil slopes, elevated walkways, and the new museum entrance.
  3. Water Infiltration Testing: Executed thorough water infiltration testing to assess the site’s hydrological characteristics.
  4. Construction Monitoring and Assistance: Provided crucial assistance in construction administration services, including precondition surveys, baseline vibration monitoring, and construction vibration monitoring for the historical Eads Bridge.
  5. Collaboration with Design Teams: Collaborated closely with three architect-led design teams, offering expertise and guidance for the main project, museum expansion, and ranger station development.
  6. Field and Laboratory Testing Services: Conducted rigorous field and laboratory testing services to ensure quality control and compliance with MoDOT specifications for construction materials, including crushed stone base course, reinforcing steel, and concrete foundations.

Additionally, Geotechnology facilitated a Phase I ESA, geotechnical desk study, and archaeological desk study to identify potential ground hazards and primary risks early in the project timeline. This proactive approach aimed to effectively manage risks associated with Recognized Environmental Conditions (RECs), hazardous substances, and archaeological sites within the project area.

In collaboration with Mound City Archaeological, a WBE (Women’s Business Enterprise) firm, Geotechnology conducted an archaeological study to assess historic, archaeological, and cultural properties that could be impacted by the JNEM grounds redesign.

The proposed project area, spanning both sides of the Mississippi River connected by the iconic Eads Bridge, necessitated meticulous attention to geotechnical, environmental, and cultural considerations. Through its multifaceted expertise and comprehensive services, Geotechnology played a pivotal role in laying the groundwork for the successful redevelopment of the JNEM grounds, ensuring both the preservation of historical heritage and the creation of a sustainable, safe, and resilient environment for future generations.

Graves Road Interchange Design-Build

Graves Road Interchange Design-Build

This project included the drilling of 148 borings to support the design-build project for the relocation of 2.3 miles of Graves Road, the widening of 2.2 miles of I-275, and the construction of a number of new structures including an interchange and bridge for Graves Road and I-275. 

The project included an expedited drill schedule and the utilization of multiple drill rigs. Borings were completed on I-275; on Graves Road; and on residential, farm, and commercial properties. Geotechnology coordinated utility locating with multiple agencies, obtained all property access permissions, provided drill rig access in wooded and sloping terrain with our own equipment and operators, and completed all restoration. The drilling included disturbed and undisturbed soil sampling as well as rock coring. All borings were completed in less than 2 months (October and November 2019), which allowed the project to remain on schedule. Geotechnology also quickly mobilized a drill rig to the site complete additional borings after a significant design change. All drilling was completed in general accordance with the KYTC
Geotechnical Guidance Manual.

Columbia Parkway Landslide Stabilization

Columbia Parkway Landslide Stabilization

Seasonal hillside instability has been a recurring problem along Columbia Parkway for decades in the form of abrupt landslides and gradual downslope movement of colluvium (soil creep). Following a series of significant landslides in multiple locations along the uphill side of the parkway, the City of Cincinnati in 2019 sought a long-term stabilization plan for 9 areas along Columbia Parkway.

Geotechnology, a UES Company, completed explorations involving borings and/or test pits on the steep terrain for evaluating the subsurface conditions for the slope stabilization designs. After evaluating the geologic conditions of the areas, Geotechnology recommended two types of stabilization mechanisms for the project: soldier pile and lagging (SPL) walls, and soil nails with steel mesh. The selection of the stabilization mechanism was based on the geometry of the ground surface and the subsurface conditions.

  • The SPL walls were used along approximately 1,500 feet of hillside parallel to Columbia Parkway near the toe of the slope.
  • The soil nail stabilization mechanism was applied to approximately 4,000 feet of slope paralleling the highway and generally extended 50 feet upslope of the lower row of soil nails.

Geotechnology prepared design plans for both the SPL walls and soil nail stabilization mechanisms. Catchments areas were included in the designs to allow material that overtops the SPL walls or soil nail stabilization areas to accumulate in the catchment areas, allowing the City to remove the materials at more opportune times when traffic demands on the parkway are less.

Geotechnology’s services included: drilling services, geotechnical laboratory testing services, and engineering design services for slope stabilization measures (soldier pile and lagging walls and soil nail stabilizations).

West Henderson Hospital

West Henderson Hospital

The Valley Health System and UHS of Delaware is constructing a new hospital on a 40-acre campus. Phase I of this project involves the construction of the North tower, which will be seven stories, and the East tower, which will be five stories; both towers involve steel-frame construction, SidePlate beam to column connections, and full-pen welded column splice connections. The $385 million hospital project will include 150 beds across both towers, which will be approximately 400,000 SF. UES is currently working on Phase 1, which is tentatively scheduled to finish in mid-2024. In future phases, the hospital will grow to include 450 beds and other improvements.

UES’ scope of work includes Quality Assurance testing and inspections on grading, utility backfill, concrete, structural steel/welding, ultrasonic testing (NDT), masonry, spray-applied fireproofing, firestopping, EIFS, post-installed anchors, floor flatness, and levelness testing.
