Rochester Buttress Construction

Coeur Mining

Lovelock, NV

Q&D built this 700,000-cubicyard, keyed-in and anchored buttress for a leach pad expansion. Existing pregnant solution lines were extended beyond the proposed fill, requiring bypassing of cyanide solution during construction to maintain mining operations. The live lines were encased with reinforced concrete to protect them from the weight of the buttress fill. Because this project was part of an ongoing mine operation, space was limited for staging. The team coordinated with mine operators daily.

Q&D managed and completed all sonic drilling, bulk sample collection and logistics for Elim Mining’s 75-million-ton Stockpile Project at their Cactus Mine near Casa Grande, AZ. With nearly 450 holes, 45,000 lineal feet of drilling and sampling, and over 30 tons of bulk sample material delivered to laboratories for assay and metallurgical testing, this work and time schedule were crucial for the project’s feasibility study. Q&D’s Mining Group provided the equipment, logistics support and project management to get the project done safely and on schedule.

Pumpkin Hollow Copper Mine

Nevada Copper / Sedgman USA

Yerington, NV

Q&D was the earthwork and grading subcontractor to Sedgman USA on this 60-acre mining project to develop Nevada Copper’s Pumpkin Hollow Copper Mine and begin production. Q&D worked closely with Sedgman to evaluate the existing site to ensure accuracy and precision. Our firm provided precise grading and subcontracted liner installation for several ditches, pads and ponds. Work also included clearing and grubbing, earthen platform construction, and HDPE pipe trenching and installation.

Tailings Storage Facility

No. 2 - Stage 1

Great Basin Gold - Aurora, NV

Located at over 7,000 feet in elevation and 25 miles up a dirt and gravel road in the hills above Hawthorne, Nevada sits the remains of Aurora, a briefly bustling mining town. Q&D was the general contractor for Great Basin Gold on this 30.5-acre tailings storage facility which required over 150,000 cubicyards of earth-moving and nearly 750,000 square-feet of 60-mil LLDPE liner.

Q&D completed earthwork – load, haul, dump, fill and dozer sloping – to build this pit wall. This wall was built from material from the south end of the pit, during active de-watering of the Paiute Pit, and during active mining operations. The work was completed on time and budget with no incidents.

CanAm Minerals

Churchill County, NV

Q&D completed reclamation of the Ivory Mine by filling and contouring multiple pits and placing a top layer of growth media over the project are for seeding - without disturbing adjacent BLM property.

Mining Projects

Taylor Mine Exploration

White Pine Metals

White Pine County, NV

Q&D completed earthwork to facilitate channel surface sampling at the historic Taylor Mine which has been mining silver since the 1870s. This exploration work resulted in new gold discoveries over an eight (8) mile zone, extending near existing surface mining pits and along previously undrilled, under-explored regions of the mine.

Beyond Mining

Tracy Pond and Inlet NV Energy McCarran, NV

For NV Energy’s Frank A. Tracy Generating Station, a natural gas facility which serves half a million households, Q&D built a new settlement filtration pond with a concrete weir and sump to serve as an inlet. It required 100,000 cubic yards of cut-to-fill material and three layers of geosynthetic liner totaling 560,000 square feet.

Gigafactory Infrastructure and Concrete Tesla

Sparks, NV

For this 250-acre campus, which houses Tesla’s 2,100,000-squarefoot Gigafactory, Q&D provided heavy/civil and structural concrete services. Q&D’s utility work at the factory included water, sewer, storm drain, fire water, industrial water, chilled water, and underground electrical and telecom conduit for the main building and the fire pump house, new well house, central utility building, hazardous waste treatment facility, and several storage yards.

Tesla also hired Q&D to construct footings and foundations for multiple phases as well as slab-on-grade and roof construction; a total of 60,000 cubic yards of concrete was placed. Q&D crews excavated 100,000 cubic yards of earth and paved approximately 2,500,000 square feet of parking for employees and storage areas.

The project began in 2015 and continues today as the plant expands and the innovative company makes changes to respond to new markets for their technology.

I-80 Carlin Tunnels Project NDOT Carlin, NV

Balancing the scope and spec requirements against the budget on this CM-at-Risk project to reconstruct roadway and improve tunnels along a major east-west, transcontinental thoroughfare took teamwork, innovation, and participation from all project stakeholders.

The innovative solution with the most impact was an alternative method to reconstruct the white paving (concrete pavement) and the resulting raising of the bridge deck structure elevation to compensate. The reconstruction was a considerable portion of the overall scope, and the difficult task of “digging out” white (concrete) pavement was expected to occupy much of the critical path. In lieu of breaking up and removing all of the white paving, placing base and then repaving, the team reviewed the option to rubbilize the white pavement (break up concrete in situ to create new road base) and repave with a modified structural section that would allow

the alignment to be completed at the correct grade.

Rubbilizing and repaving added 8 inches to the roadway elevation and would not match grade with the bridges. Since the bridge repair included installation of new seismic isolators, the team strategized to raise the superstructure elevation 8 inches and redesigned the isolators to include the additional 8 inches. Between these two innovative processes, the rubbilization of existing pavement and the raising of multiple bridge deck structures, the

ENVIRONMENTAL STEWARDSHIP

It takes a lot of trust in your reputation and skill before public agencies will let you drive a backhoe into one of the most regulated bodies of water in the United States. Or install a temporary diversion in a river that supplies 85% of the drinking water to over 800,000 people. Or revise an erosion control channel at the largest alpine lake in the United States. The results of our skill meeting our clients’ and authorities’ environmental specifications is that when we are finished, it looks as though we were never there.

Truckee River Restoration

Reversing well-intentioned changes to a precious environment and natural resource

The Truckee River serves many communities along its 121-mile route from Lake Tahoe on the Nevada-California border to Nevada’s Pyramid Lake. From recreation to farming to drinking water, it is a thriving part of the ecosystem and economy.

Over the years, the Truckee has been modified with dams and diversion structures which, along with efforts to reduce flooding in the nearby Truckee Meadows basin, have negatively impacted the riparian environment.

As part of a joint effort across municipalities and local, state and federal agencies, the restoration of the Truckee River to its natural course in several key areas is just one of numerous projects that together comprise a comprehensive flood mitigation

strategy for nearby towns and cities at risk.

For the stretch of river pictured here, Q&D’s grading and trucking crews moved approximately 250,000 cubic yards of earth to realign the Truckee River with its natural path.

Working in the waterway using backhoes, skilled equipment operators carefully placed 80,000 tons of rock for slope stabilization and built a bench for a major gas line relocation - all with minimal disturbance to river water quality and habitat. This is one of several restoration projects Q&D has undertaken for this client and one of many projects Q&D has completed that are connected to the region’s overall flood mitigation plan like the North Truckee Drain and The Virginia Street Bridge.
