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.

Earthwork for construction of maintenance hangar at DIA for Southwest Airlines including demolition of taxiway shoulder and snow road, import of 100,000 CY of selection embankment material, import of 100,000 CY of general fill, 150,000 CY of onsite cut to fill and aggregate production, including sizing and crushing, of 50,000 TN of Class 6 ABC and selection embankment material.

The Crossroads project consisted of 1.6 miles of complete highway reconstruction, two bridges spanning 176 feet for I-25 North & South Bound highway, and reconstruction of Crossroads Boulevard beneath the bridges.

The scope of work included removal of asphalt, concrete pavement and rubblized pavement, detour construction and removal, excavation, export, subgrade stabilization, road base, storm sewer, bridge construction, asphalt paving, concrete paving, striping, signage, traffic control, public safety and landscaping.

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.

This was a high profile highway interchange improvement project lowering US-6 approximately 26 feet and constructing a bridge over 19th street connecting City of Golden and Lookout Mountain.

The project had multiple stake holders including, CDOT, City of Golden, Colorado School of Mines, students, citizens, bicycling community and local small business. The project scope of work included extensive tree removal, clearing, surface and utility removals, excavation of 183,000 cubic yards, complicated traffic detours, several soil nail walls with precast panel facing, bridge construction with a small amphitheater, asphalt paving, striping, signage, traffic control, public safety and landscaping.

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.
