The Trails at Crowfoot is a master residential development community encompassing 330 acres located in Parker Colorado along North Crowfoot Valley Road with over 5,000,000 cubic yards of overlot & over excavation, erosion control, wet utilities, dry utilities, concrete flatwork, asphalt paving, concrete paving for acceleration, deceleration, and turn lane additions, concrete sculpted drop structures, landscaping, irrigation, monumentation and park construction.

The project was located between US36 and Ward in Boulder County and included approximately 11 miles of roadway and stream rehabilitation and reconstruction.

The work included clearing and grubbing, roadway excavation, blasting, grouted riprap and boulder installation, production of aggregate base course from material excavated onsite, aggregate base placement, storm sewer systems, asphalt paving, guardrail, striping, traffic control and stream channel restoration and rehabilitation.

Wyoming Highway 257, also known as the West Belt Loop Road, links Wyoming Highway 220 to U.S. Highway 20/26.

The two-lane route is about 7.5 miles long and features two bridges. The road also offers a view of Casper Mountain. We constructed Phase 1 of the highway which included excavation and placement of approximately 3.0 million cubic yards of dirt, bridge construction over the North Platte River and Unnamed Draw, and realignment of Robertson and Poison Spider Roads.

The Airport project including hauling and placement of 1,750,000 CY of fill material for a future 1,000 foot runway extension.

Installation of approximately 1,300 feet of 114” culvert and 7,500 SQ. FT. of MSE wall. Eagle County Airport was a challenging project due to a tight schedule which required the project to be completed between April and November due to commercial flight operations. Additionally, FAA security measures had to be maintained throughout the project.

The project consisted of roadway construction realignment and new runway expansion preparation including 2,175,375 cubic yards of embankment, production blasting, trench blasting, water line, sanitary sewer, storm sewer, utility trench excavation and backfill, grouted boulder drop structures, asphalt paving, signage, striping and seeding.

We provided a value engineering construction concept eliminating soil cement construction and replacing it with mechanical stabilized earth panel wall construction saving the project significant cost and critical schedule duration.

Project consisted of building a new safety area for Runway 11L to come into compliance with FAA standards and a new Run Up Area for Taxiway “A”.

​

Major items of work on the project performed by KTI included embankment of 857,888CY, including 340,000CY of select fill from designated borrow sites. The majority of the embankment material was obtained from two borrow sources designated by the airport. A large portion of the borrow material was long haul (3/4 mile each way) and included crossing a major traffic thoroughfare of which KTI provided signalization.

A major component of the work was construction of a 26,250SF Reinforced Soil Slope which included 140,000CY of Select Fill and over 180,000SY of Geotextile Reinforcement and installation of topsoil filled Geocell on the face of the slope.

​

Placement of 6,700TN of Aggregate Base Course Class 6 was placed for construction of a new perimeter road and 2,300TN of P-209 Crushed Aggregate Base Course for the new Run Up Area.

​​

KTI also installed 1,666LF of RCP Storm Sewer and 700LF of underdrain.

Excavation of approximately 1.2 million cubic yards of site soils for landfill cell construction with cohesive soil and geosynthetic liner construction.

The project was designed and constructed by FAA guidelines and was necessary to widen taxiway safety areas from Aircraft Design Group (ADG) IV to a minimum of ADG V standards.

Construction included widening the taxiway area a minimum of 21.5’ on each side of the taxiway, including embankment of 250,000CY of earth, drainage infrastructure modifications and utility adjustments or relocations. Earth for the taxiways safety area widening project was obtained from the future RTD FasTracks Station and South Terminal Development location at the south end of the Jeppesen Terminal.

We have constructed multiple cells at North Weld Landfill including Phase 3a Module 1 & Phase 3b Module 1. The liner systems included over 1.0 million cubic yards of excavation, over 60,000 cubic yards of clay liner, leachate drainage, sand drainage layer and leachate sump construction.

Hodgson-Harris Reservoir Dam was an earthfill dam re-construction including removal and replacement of outlet works conduit and structures, upstream riprap, and blanket and toe drains.

The project included temporary cofferdam and stream diversion, dewatering, strip and stockpile Topsoil - 2,400 cubic yards, excavate and stockpile existing riprap - 400 cubic yards, unclassified excavation – 6,350 cubic yards, embankment Fill – 7,600 cubic yards, filter sand – 450 cubic yards, drain aggregate, place riprap – 1,050 cubic yards, reuse riprap – 400 cubic yards, dam foundation excavation and preparation, 6 inch PVC drain pipe – 290 lineal feet, cast-in-place outlet works, 18 inch precast concrete pipe and concrete cradle – 122 lineal feet, 18 inch sluice gate and operator, cast-in-place concrete spillway, cast-in-place concrete spillway grade control structure, Dam instrumentation, erosion control, site reclamation, project surveying including local control, layout, as-built verification

The rehabilitation of Woman Creek Dam and Reservoir consisted of constructing interior toe buttresses along the upstream dam slope and remaining south interior berm within the reservoir.

The new toe buttresses were constructed with approximately 5,000 tons of imported squeegee sand fill and 60,000 cubic yards of on-site soils, 3,650 cubic yards of riprap, and 2,200 cubic yards of riprap bed course borrowed from the existing North interior buttress that was removed in the construction process.

The work entailed stockpiling existing riprap and bed course for reuse, excavation and installation of sand drains, importing and installation of squeegee sand fill into existing buttress riprap, constructing the toe berms with on-site North Internal Berm soil excavation, construction of riprap buttress drain, and placement of riprap and bed course along the lower portion of the buttresses.
