2C Road Improvement
Citywide road program, Colorado Springs, CO
In 2015, Colorado Springs voters approved the 2C sales tax to tackle a backlog of failing streets, and they renewed it in 2019 and again in 2024. Since the program began in 2016 it has repaved more than 1,900 lane miles, rebuilt roughly 400 miles of curb and gutter, and installed thousands of new and retrofitted pedestrian ramps across the city — one of the largest sustained paving efforts in Colorado, with about half of every dollar going to the concrete beside the road. Vivid Engineering serves as one of the lead quality assurance testing firms for the program's concrete and asphalt work. Our technicians test and document paving, sidewalks, curbs, gutters, and pedestrian ramps across each year's project list, verifying that every placement meets City specifications. That oversight protects the long-term durability of the investment and helps the City deliver smoother streets and better accessibility, year after year.

30th Street Corridor
30th Street, Fontanero Street to Garden of the Gods Road, Colorado Springs, CO
30th Street is the main route into Garden of the Gods Park, carrying park visitors, neighborhood traffic, and cyclists on a narrow, winding two-lane road with little margin for error. The City of Colorado Springs' 30th Street Corridor Improvement Project rebuilt roughly three miles between Mesa Road and Fontanero Street: widening the roadway with paved multi-use shoulders, adding a roundabout at Gateway Road, upgrading intersections, building a pedestrian underpass, and installing a new storm sewer system with a water quality pond. More than 2,000 feet of retaining walls and 6,300 feet of soldier pile were needed to hold the widened road on the hillside. Vivid Engineering led quality assurance testing and served on the construction inspection team for the project, verifying soils, concrete, and asphalt — including some 14,000 tons of asphalt and 21,000 feet of curb and gutter — against project specifications. The improvements strengthened emergency access and evacuation routes and created safer travel for motorists, cyclists, and pedestrians on the way into one of the region's most visited parks.

Academy Boulevard Improvements
South Academy Boulevard, Bijou Street to Airport Road, Colorado Springs, CO
South Academy Boulevard is one of Colorado Springs' hardest-working arterials, and decades of heavy traffic had left its pavement, concrete, and drainage in poor condition. The City's $62.5 million South Academy Boulevard Improvements Project, funded through the voter-approved Pikes Peak Rural Transportation Authority, is rebuilding 18 lane miles in two segments — Bijou Street to Airport Road, and East Fountain Boulevard to Jet Wing Drive. The work replaces worn pavement and base, rebuilds curb and gutter, adds a multi-use path, relocates Colorado Springs Utilities water and wastewater lines, and installs new inlets, manholes, and storm pipe to end chronic standing water. Vivid Engineering leads quality assurance testing and is part of the inspection team for the project. Our technicians sample and test soils, aggregate base, concrete, and asphalt as each phase goes in, keeping results in the contractor's hands so work can keep moving through a corridor that stays open to traffic throughout construction. Segment 1 wrapped up in 2024, with the southern segment scheduled for completion in 2026.

Cañon City's 2A Street Repair
1st Street and Main Street, Cañon City, CO 81212
In November 2016, Cañon City voters approved Referendum 2A, a one-percent sales tax dedicated entirely to repairing and replacing the city's streets. The 2024 program year was one of the largest to date: a $6.55 million slate that included full reconstruction of 1st and Main Street from US 50 to 4th Street and Pear Avenue from 19th Street to Field Avenue, along with resurfacing of 5th Street between Fairview Avenue and High Street and Harrison Avenue between 9th and 15th Streets. Year by year, the 2A program has worked through the roughly two-thirds of city streets once rated in poor condition. Vivid Engineering served as project manager and the inspection and testing lead for the 2024 work — managing construction on the City's behalf, inspecting reconstruction and paving operations, and testing soils, aggregates, concrete, and asphalt against project specifications. The result is a set of rebuilt downtown streets that meet national standards and will serve Cañon City for decades.

Central 70 Project
I-70, Brighton Boulevard to Chambers Road, Denver, CO
Central 70 was the largest project in CDOT's history: a $1.2 billion reconstruction of 10 miles of Interstate 70 between Brighton Boulevard and Chambers Road, a corridor that carries more than 200,000 vehicles a day and supports some 1,200 businesses. The project added a new express lane in each direction, removed a 56-year-old viaduct, lowered the interstate between Brighton and Colorado Boulevards, and built a four-acre park over the highway to reconnect the Elyria-Swansea neighborhood to the rest of the city. Working alongside Kiewit Infrastructure Co., Vivid Engineering provided process control and field and laboratory materials testing for the project. Our technicians tested soils, concrete, asphalt, masonry, shotcrete, and aggregates throughout construction, verifying that every material placed met CDOT's quality standards on one of the most complex urban highway builds in the country.

Church Ranch Corporate Center Environmental Assessment
Church Ranch Corporate Center, Church Ranch Boulevard, Westminster, CO 80021
The Church Ranch Corporate Center sits on a property with more than 120 years of history — barns, silos, farmhouses, and office buildings that Dominium Development & Acquisition purchased with the goal of preserving the site's character while redeveloping it for new businesses. Before that could happen, the environmental condition of both the land and the buildings had to be understood and cleared. Vivid Engineering supported Braun Intertec over three years of work on the site, beginning with a Phase I Environmental Site Assessment. A subsequent Phase II ESA identified soil and groundwater contamination from a previously removed underground storage tank; Vivid's follow-on subsurface investigations defined the groundwater plume, with approval from the Colorado Division of Oil and Public Safety, allowing Braun Intertec to secure a "No Further Action" determination from the State. Vivid also performed hazardous building materials assessments on multiple structures, including the historic barn and silo — sampling for asbestos, lead-based paint, PCBs, and mercury and delivering reports with abatement recommendations — so the redevelopment could proceed safely.

Circle Drive Bridges Replacement Project
Circle Drive, Janitell Road to Monterey Road, Colorado Springs, CO
Four bridges built in 1963 carry South Circle Drive more than 60 feet above Fountain Creek, the BNSF Railway, Las Vegas Street, Hancock Expressway, and the Pikes Peak Greenway Trail — a critical link between I-25 and southeast Colorado Springs. After a life-cycle cost analysis, the City chose full replacement over rehabilitation. The PPRTA-funded Circle Drive Bridges Replacement Project, built by SEMA Construction, began in fall 2023 and is replacing all four 800-foot structures in phases: new eastbound bridges first, alongside the originals, then new westbound bridges once traffic shifts — all while keeping two lanes open in each direction. The project also adds a sidewalk connection to the Greenway Trail and bike and pedestrian improvements on Hancock Expressway. Vivid Engineering leads quality assurance testing and supports the inspection team for the project, testing structural concrete, soils and backfill, and asphalt through each construction phase so that the new bridges meet City and CDOT standards for the next 60 years.

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. 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.

CO 119 Safety, Mobility & Bikeway Project
CO 119 (Diagonal Highway), Foothills Parkway in Boulder to Hover Street in Longmont
CO 119 — the Diagonal Highway — is Boulder County's busiest commuter corridor, linking Boulder and Longmont across 10 miles of open farmland and a growing string of intersections. CDOT's $165 million CO 119 Safety, Mobility & Bikeway Project, delivered in two construction packages with Kraemer North America and funded by CDOT, RTD, Boulder County, and a 2023 federal RAISE grant, is reshaping the corridor from Foothills Parkway to Hover Street. The project adds a separated commuter bikeway running the length of the highway, with four underpasses at CO 119, Niwot Road, CO 52, and Jay Road and an overpass at 63rd Street; new Bus Rapid Transit infrastructure and Park-n-Ride facilities; a reconfigured CO 52 intersection; and safety improvements at intersections along the route. Construction began in September 2024, with completion expected in spring 2027 — all while the highway stays open to the tens of thousands of commuters who depend on it every day. Vivid Engineering Group provides field and laboratory materials testing across both construction packages, working alongside Kraemer and CDOT Region 4. Our technicians sample and test soils, aggregate base course, concrete paving (PCCP), structural concrete for bridge decks, caissons, and drainage structures, and asphalt, performing CDOT owner acceptance sampling and testing to verify that every material placed meets specification, with samples run through Vivid's AASHTO-accredited Colorado laboratories. On site since 2024, the team has supported early-morning fast-track paving pours, bridge deck placements, caisson pours, and embankment work — keeping acceptance testing and documentation moving at the pace of one of the fastest-moving corridor projects in the state.

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. 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.

DENVer On-Call Environmental Testing
Denver International Airport, 8500 Peña Boulevard, Denver, CO 80249
Denver International Airport is in the middle of a sustained building program — terminal and concourse renovations, new ground transportation facilities, and upgrades to utility vaults and operations buildings — nearly all of it inside secured, high-traffic areas that never close. Before any of that work can begin, the City and County of Denver needs to know what is in the walls, ceilings, and soils that construction will disturb. Vivid Engineering provides ongoing environmental testing and assessment at DEN under an on-call contract with the City and County of Denver. Our work has included asbestos and mold testing, Phase I Environmental Site Assessments, lead-based paint inspections, industrial hygiene consulting, and personal exposure air monitoring for projects such as the former toll plaza on Peña Boulevard, the Ground Transportation Facility, terminal stairwells, Xcel vaults in several concourses, and the entire Airport Operations Building. We sample and test for asbestos in buildings and soils, analyze lead-based paint, and design abatement or containment methods when needed — coordinating every entry through secured areas so airport operations are never disrupted.

Downtown Estes Loop Project
Elkhorn Avenue, Moraine Avenue, and Riverside Drive, Estes Park, CO 80517
Every year, millions of visitors funnel through downtown Estes Park on their way to Rocky Mountain National Park — and for decades, its two-way downtown streets could not keep up. The $42 million Downtown Estes Loop, administered by FHWA's Central Federal Lands Highway Division in partnership with CDOT and the Town of Estes Park, converted Elkhorn Avenue (US 36), Moraine Avenue, and Riverside Drive into a one-way couplet. The project built a new roundabout at Moraine and West Riverside, replaced the bridge over the Big Thompson River connecting East and West Riverside Drives, and delivered expanded stormwater infrastructure, floodplain mitigation, and new sidewalks and trails through the heart of downtown. Working for Flatiron, Vivid Engineering Group provided construction inspection plus field and laboratory materials testing of soils, aggregates, concrete, and asphalt across 21 months of construction, from January 2023 to October 2024. Building a federal-aid project through an operating tourist downtown meant compressed winter work windows and some of the toughest environmental restrictions on any Colorado project — with the Big Thompson River flowing directly through the work zone. Vivid's inspectors and technicians kept quality verification moving on the contractor's schedule, with samples run through our AASHTO-accredited Colorado laboratories, so that the Loop opened to traffic ahead of the next summer season.

Garden Of The Gods Flood Mitigation Facility
Garden of the Gods Road at Camp Creek, Colorado Springs, CO 80904
After the 2012 Waldo Canyon Fire burned much of the Camp Creek watershed, storm runoff into the neighborhoods below Garden of the Gods became a serious flood risk. The City of Colorado Springs' answer was a stormwater detention and sediment collection facility in the park's northeast corner, funded through FEMA's Hazard Mitigation Program with state and city dollars. Built by Mortenson Construction, the $7.8 million facility includes a 27-foot earthen embankment, roughly 170 acre-feet of storage, a 365-foot roller-compacted concrete spillway, an 8-by-6-foot reinforced concrete outlet box, and a realigned grouted-boulder channel to carry Camp Creek — about 185,000 cubic yards of earthwork in all. Completed in December 2020, the facility helps protect more than 100 properties along the 31st Street corridor. Vivid Engineering provided construction engineering, inspection, and materials testing for the project, working with Mortenson and the City to verify the quality of earthwork, compacted embankment, concrete, and grouted boulder construction — the elements the facility's long-term flood resilience depends on.

I-25 South Gap Project: Monument To Castle Rock
I-25, Monument to Castle Rock, CO (18 miles)
For years, the 18-mile stretch of I-25 between Monument and Castle Rock was the only four-lane section left between Denver and Colorado Springs — a congested, crash-prone bottleneck known simply as "the Gap." CDOT's $350 million I-25 South Gap Project, delivered through the CM/GC method with Kraemer North America, widened the interstate to three lanes in each direction with a new express lane, reconstructed five bridges, extended ramps, built five wildlife crossings to reduce animal-vehicle collisions, and placed a new pavement overlay along the full length of the corridor. Construction ran from 2018 through 2022. Partnering with Rocksol Consulting Group, Vivid Engineering provided owner's acceptance inspection and materials testing for CDOT on the project. Vivid inspectors and technicians covered drainage features, retaining walls, bridge structures — including caisson and bedrock observations at the new bridge foundations — and pavements, along with test pits and DCP testing to confirm subgrade conditions, verifying that the work met CDOT's standards on one of the most heavily traveled corridors in the state.

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. 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.

I-70 Floyd Hill to Chief Hosa Resurfacing
I-70, Chief Hosa to Floyd Hill (MP 246.5 to 252.9), Jefferson and Clear Creek counties, CO
Between Floyd Hill and Chief Hosa, I-70 climbs through the Front Range foothills carrying ski traffic, freight, and daily commuters in and out of the mountains — and its pavement had reached the end of its life. CDOT's $12.8 million resurfacing project rehabilitated 6.4 miles of the interstate (MP 246.5–252.9) through Jefferson and Clear Creek Counties, milling off deteriorated pavement and repaving both directions in stone matrix asphalt (SMA) — the durable, rut-resistant surfacing CDOT reserves for its hardest-working corridors. With no practical detour around this stretch of the mountains, contractor APC Construction completed all paving in a single season, almost entirely under nighttime lane closures, then returned the following season for guardrail replacement, culvert cleaning, signage, and striping. Working directly for CDOT, Vivid Engineering Group provided construction inspection, QA/QC administration, and field and laboratory owner acceptance materials testing across the project. SMA is one of the most demanding mixes to test — gap-graded, fiber-stabilized, and unforgiving on volumetrics — so Vivid ran the entire laboratory acceptance program from its on-site field lab, turning results while the mat was still going down. Vivid inspectors and certified technicians worked the night closures alongside the paving crews, verifying mix temperatures, compaction, and placement in real time; high-altitude paving windows, mountain weather, and live interstate traffic made every shift count, and Vivid's team kept acceptance testing and documentation moving on the contractor's schedule so the corridor reopened to full capacity every morning.

Military Access, Mobility & Safety Improvement Project
South Academy Boulevard widening and Pikes Peak region corridors, El Paso County, CO
The Military Access, Mobility & Safety Improvement Project (MAMSIP) is a $161 million, five-year program to improve the corridors connecting Fort Carson, Peterson Space Force Base, Schriever Space Force Base, and Cheyenne Mountain Space Force Station — funded by CDOT, El Paso County, the Pikes Peak Rural Transportation Authority, and an $18.35 million federal BUILD grant. Built by SEMA Construction from June 2021 to July 2026, the program delivered safety improvements and a jug-handle intersection on CO 94; a full rebuild of Charter Oak Ranch Road with a new roundabout at Santa Fe Avenue; 7.5 miles of I-25 work between South Academy Boulevard and Fountain, including two replacement bridges, a concrete overlay, and a full-length median barrier; and finally the widening of South Academy Boulevard from two to three lanes in each direction, with bridge widening over Fountain Creek, US 85/87, and Bradley Road. Vivid Engineering served as the lead materials quality assurance testing firm for the program, overseeing all materials documentation, field testing, and inspection — including the South Academy Boulevard widening in El Paso County — to verify that every element met CDOT and FHWA standards for safety and durability.

Ridgegate Parkway Widening
RidgeGate Parkway, I-25 to Meridian Village Parkway, Lone Tree, CO 80124
RidgeGate Parkway is the spine of Lone Tree's fast-growing RidgeGate development, linking I-25 and the Lone Tree City Center to the neighborhoods east of the interstate. To keep pace with that growth, the RidgeGate Parkway Widening Project expanded the corridor between I-25 and Meridian Village Parkway to add two through-lanes in each direction, including a split-alignment section, new bridges over Badger Gulch and Happy Canyon Creek, 8-foot pedestrian sidewalks, and a 12-foot cycle track running the length of the project. Partnering with Hamilton, Vivid Engineering provided construction field and laboratory materials testing for soils, concrete, and asphalt throughout the project. Our technicians tested embankment and backfill compaction, structural concrete for the new bridges, and asphalt paving as the corridor was built out, verifying that every element met the project's quality standards and giving the contractor results on the schedule the work demanded.

SH 7 Permanent Repairs Project
CO 7, South St. Vrain Canyon, Lyons to Raymond (MP 19 to 33), Boulder County, CO
The September 2013 flood devastated Colorado Highway 7 through the South St. Vrain Canyon, severely damaging or completely washing away nine miles of roadway and cutting off canyon access for two and a half months. Temporary repairs reopened the road, but a permanent fix had to wait. The SH 7 Permanent Repairs Project — the final permanent infrastructure project of Colorado's $750 million 2013 Flood Recovery Program, funded through FHWA Emergency Relief — permanently rebuilt 14 miles of the canyon between Lyons and Raymond. The $60 million project replaced temporary post-flood asphalt with a fully reconstructed roadway, restored 11,500 linear feet of St. Vrain Creek to a resilient natural channel, rebuilt embankments and drainage, added rockfall ditches and a four-foot uphill bicycle shoulder, and revegetated 28 acres of disturbed canyon — all while meeting a net-zero construction waste goal. Vivid Engineering Group worked alongside Kiewit Infrastructure Co. and CDOT Region 4 from September 2021 through November 2022, providing field and laboratory materials testing of soils, aggregates, concrete, and asphalt to verify that every material placed met CDOT standards — including the 38,500 tons of asphalt that make up the new canyon roadway. In a narrow canyon with a single access road and an active creek restoration underway, Vivid's technicians kept sampling and testing on the contractor's schedule so the corridor could reopen as planned.
