Millcreek City Hall

Millcreek City Hall

UES is providing construction materials testing and inspections on the new Millcreek City Hall. This six-story concrete and glass structure will feature a basement, ground-floor market and exposition place, four city and police operations floors, a sixth-floor community center reception hall, and an outdoor climbing wall. UES’ testing and inspection services include soil inspections; concrete inspections, including strand placement; steel bolting inspections; steel welding inspections; miscellaneous steel inspections, including roof and floor deck welding; mass timber inspections; post-installed anchor inspections; non-structural component inspections, including exterior cladding and mechanical/electrical components; and review of deferred submittals.

The most significant benefit that UES provides for this project is proactive preliminary inspections. During a pre-construction meeting for post-tension, our team identified design irregularities that were addressed before the work began, saving substantial time and the potential costs associated with revised construction. Being a proactive and involved member of the project team is something we value at UES because those characteristics exemplify our core values. This standard of excellence is why our clients continue to trust UES to help complete projects.

The new facility was a Design/Build project consisting of approximately 478,000 SF facility allowing for 1,216 beds. This $270 million project was designed in two phases.

UES served as the Geotechnical Engineer of Record for the project and provided construction control services including grading control, utilities, pad certification, foundation inspection and certification, and soil and asphalt compaction testing and inspection. We also provided air monitoring during rough grading in accordance with the County Department of Environmental Health approved work plan and performed special inspection and engineering support services, including re-enforced concrete and masonry, field and shop welding inspection, Non-destructive Examination of Welds (NOE), fireproofing inspection, and all soils and materials testing services required for the project. The total contract value for was $398k.

Plans to develop a new detention facility on historically agricultural land required a team approach. The new facility included Levels I-VI housing units, protective custody, an intake facility/transfer/release facility, maintenance and energy facility, food service building, Facility Administration, Security Administration, Laundry, Medical Services, parking for staff and visitors, and security perimeter structures. The project commenced with UES’ Environmental Evaluation; the work included close interface with the County of San Diego Department of Environmental Health’s Voluntary Assistance Program. Based upon results of testing for organochlorine pesticides (OCP), a Soil Management Plan and a Community Health and Safety Plan were created to include soil and air monitoring during mass grading of the site. Upon completion of grading and continuous air monitoring a site closure letter was obtained, which documented completion of project environmental goals. Geotechnical engineering and testing/inspection services followed.

NASA Headquarters Building Central Campus

NASA Headquarters Building Central Campus

UES is proud to be a part of this two-year, $64.8 million contract to demolish and build a seven-story new headquarters structure. The new building will be the centerpiece of what KSC calls the Central Campus, an initiative to replace aging Industrial Area facilities with more energy-efficient structures while occupying a smaller footprint. It will replace the center’s existing headquarters, a roughly 50-year-old building.

The new building will be an ultra-modern Headquarters Building; a seven-story, 200,000-SF structure. The building is being designed to house about 500 people. The new Headquarters Building will include numerous features to enhance its environmental efficiency and affordability. The total area of the construction site is 5.5 acres, including the building, parking, roadways and walkways. The building is a concrete frame with a steel frame roof and canopy. The building foundation consists of 390 driven piles on pile caps. Ancillary construction includes on-site and off-site sitework with paved parking/roadways. The on-site sitework includes the removal and replacement of nine feet of soil beneath the building pad. The off-site sitework includes drainage improvements in the central campus area.

UES provided a Certified Welding Inspector and Senior Engineering Technicians for Pile Driving Inspections, CAPWAP and WEAP Analysis, Static Load Test (Quick Load method), Moisture/Density Relationship (Proctor) Tests, Limerock Bearing Ratio Tests, Asphalt Extraction Gradations, Asphalt Core Thickness, and Density Tests, Concrete Test Cylinders, Concrete Monitoring, In-place density tests, and Floor Flatness Tests (using F-Meter)

Naval Facilities Engineering Command Southwest Berth Lima Conversion

Naval Facilities Engineering Command Southwest Berth Lima Conversion

Upgrades to Berth Lima at Naval Base Coronado accommodated planned industrial maintenance activities and cold-iron berthing for the Nimitz-class nuclear aircraft carriers home-ported in San Diego. Construction included a security building, pump house building, restroom/payphone building, two masonry and steel watch towers, two guard houses, security fencing, high-mast security lighting, upgrades to underground water and electric utilities, and surveillance infrastructure. Waterfront upgrades included the replacement of asphalt with new quayside concrete pavement capable of supporting 40-ton forklifts. The project also involved widening the existing quay wall by two feet and installing 80 new primary fender piles, fender panels, and armor rock.

UES performed an update of preliminary geotechnical investigation, detailed analyses, and evaluation of the proposed concrete pavements, as well as soil/cement treatment of the existing subgrade materials in order to eliminate export of soils and import of aggregate base. Building pad preparation involved mitigation of shallow beach sand materials. Due to the shallow groundwater conditions at the site, high-strength, biaxial, geotextile reinforcement was designed for use in stabilizing local subgrade areas. Upon completion of proper geotechnical mitigation at the site, cost-effective, shallow, reinforced concrete spread foundations and slabs-on-grade were suitable for support of structure improvements. UES provided all requisite onsite inspection of reinforced concrete; masonry; radiographic inspection; inspections of welding roofing and fireproofing; and laboratory testing of soils, concrete, masonry, and steel.

Herbert Hoover Dike Rehabilitation

Herbert hoover dike rehabilitation

The Herbert Hoover Dike Rehabilitation Structure Replacements project is a critical initiative aimed at addressing the urgent repair needs of the nation’s dams, with a particular focus on the Herbert Hoover Dike (HHD). Recognized as a top priority by the U.S. Army Corps of Engineers since 2007, the HHD has received substantial funding for repair, making it the most funded dam construction project in the country.

To date, the project has achieved significant milestones, including the construction of over 21 miles of cutoff walls in Reach 1. These cutoff walls serve as an internal solution, eliminating existing piping and preventing additional erosion throughout the dike, foundation, and limestone layers. Each contractor involved in the project is required to demonstrate their process through a 500-foot test section, ensuring compliance with Corps specifications.

The construction of the giant wall reaches depths of up to 80 feet below the crest, extending into the foundation and reaching 5 to 10 feet below the limestone layer. Rigorous quality assurance testing occurs before, during, and after cutoff wall construction to ensure adherence to specifications.

UES, through its involvement in Task Orders #3, #7, and #8, has played a crucial role in providing quality control testing and inspections. This includes overseeing cutoff wall construction totaling 16,900 feet, 16,795 feet, and 3,340 feet in Task Orders #3, #7, and #8, respectively.

The broader project involves the demolition and removal of existing structures, such as Herbert Hoover Dike Culverts 12A, 2, 8, and 13. New water control structures, including S-274, S-278, S-268, S-272, and S-271, are being constructed at their respective locations. The reconstruction efforts involve the installation of cofferdams, cast-in-place reinforced concrete foundations, headwalls, culvert barrels with steel liners, and sheetpile scour cutoff walls.

Additionally, the project includes the installation of combination flap/slide gates, cutoff walls in the embankment centerline, reconstruction of embankments to match existing crest elevations, riprap installation, control buildings, and other essential components. UES’s involvement extends to quality control testing and inspections, ensuring the successful execution of these reconstruction efforts.

Furthermore, UES has actively participated in the construction of approximately 2200 linear feet of cutoff wall in Reach 1 of the Herbert Hoover Dike embankment. This specific effort addressed gaps around water control structures and involved both conventional cutoff wall and jet grout cutoff wall construction methods. The project encompasses comprehensive measures to enhance the dike’s structural integrity and protect against erosion, contributing significantly to national dam safety programs.
