Geotechnical Engineering

Our Geotechnical and Geological Engineering services provide expert solutions for complex subsurface conditions — from comprehensive subsurface investigations and lab testing to specialized designs for earthwork, foundations, pavements, drainage, and walls.

Reliable engineering from the ground down.

Vivid Engineering’s geotechnical and geological engineering practice provides solutions for complex subsurface conditions. From subsurface investigations and geotechnical lab testing to designs for earthwork, foundations, floor systems, and pavements, we deliver engineering matched to each project’s needs.

Our team specializes in slope and rock stability, landslide and rockfall mitigation, and forensic evaluations. Whether it’s a small development or major infrastructure like the Cheyenne Canyon bridges or the Garden of the Gods pedestrian bridge, Vivid brings the same care to the ground under every project.

    City of Cañon City Referendum 2A Program

    Citywide street program, Cañon City, CO 81212

    In November 2016, Cañon City voters approved Referendum 2A, a one-percent sales tax increase dedicated exclusively to contracting out street repair and replacement. The tax generates an average of $3.5 million a year across a 10-year program — $9 million of design-build work in the first year, 2017, followed by annual design-bid-build programs every year since.<br /> <br /> Vivid serves as the City's prime consultant and owner's representative for the program. Our team performs geotechnical investigations; prepares pavement designs for composite pavement, full-depth reclamation, and asphalt and concrete mill-and-overlay; and delivers civil plans and specifications covering roadway plan and profile, utility relocations, drainage, streetscape and ADA compliance, Safe Routes to School, stormwater management, quantities, and engineer's estimates, with Wilson & Company preparing civil plans as a subconsultant. Vivid supports bid document preparation, bid award, and pre-construction meetings, then serves as construction engineer through the build — providing construction inspection, quality management, and materials testing on every project. The result is a program that has steadily rebuilt the streets Cañon City residents voted to fix.

    Colorado's Power Pathway

    Approximately 550 miles of 345 kV transmission line across twelve eastern Colorado counties, Fort St. Vrain to Harvest Mile

    Colorado's Power Pathway is Xcel Energy's $1.7 billion expansion of the state's high-voltage grid: approximately 550 miles of new double-circuit 345 kV transmission line looping through twelve counties of eastern Colorado, along with new and expanded substations, built to deliver roughly 5,500 megawatts of new wind and solar generation planned through 2030. The line runs from the Fort St. Vrain generating station in Weld County south through Morgan, Kit Carson, Cheyenne, Kiowa, Crowley, and Pueblo Counties, then back north through El Paso, Elbert, and Arapahoe to the Harvest Mile substation — one of the largest transmission builds in the western United States. The first segments entered service in spring 2025, with full program completion expected in 2027.<br /> <br /> Vivid Engineering Group has served as owner's representative on all five segments of the program, providing quality assurance testing and inspection of transmission structure foundations and substation sites, along with geotechnical engineering. On site since 2023, our field teams and geotechnical engineers have verified the integrity of the drilled foundations that carry every steel structure along the route and supported construction at the program's new substations — Canal Crossing, Goose Creek, and May Valley — as well as expansions of existing facilities. Working across the open plains of eastern Colorado, often far from the nearest laboratory, Vivid's crews have kept sampling, testing, and inspection moving at the pace of the build, segment after segment, from the first foundation to the last.

    I-25/Cimarron Interchange Design Build

    I-25 and Cimarron Street (US 24) interchange, Colorado Springs, CO

    The I-25/Cimarron Street (US 24) interchange is the gateway to downtown Colorado Springs and one of the busiest junctions in the Pikes Peak region. Decades of poor roadway performance — settlement of embankments and walls on soft soils along Fountain Creek — had made it a persistent maintenance problem. CDOT's $77 million design-build reconstruction, delivered with Kraemer North America, completely rebuilt the interchange: new bridge foundations and bridges, new embankments, numerous MSE retaining walls, temporary and permanent pavements, improvements to the major drainages, and culvert and jack-and-bore utility installations.<br /> <br /> Vivid Engineering supported the project with quality oversight, construction inspection and materials testing, geotechnical design, and structural fill monitoring. Because of the corridor's history of settlement, significant analysis, design, and construction monitoring were performed to protect the new embankments and retaining walls — work grounded in our team's deep experience with DOT and FHWA design-build requirements, procedures, and specifications. The result is a modern interchange built to perform on ground that had troubled the corridor for decades.
