Lumos provided base mapping, potholing, geotechnical investigation, hydraulic modeling, improvement plans, specifications, permitting, construction management, construction inspection, materials testing, and construction staking for this $7.1 million sewer interceptor improvement project. Major work items included the construction of a 5 MGD sanitary sewer lift station, the installation of approximately 4,500 lineal feet of 20-inch HDPE force main, installation of approximately 1,900 lineal feet of gravity sewer main ranging from8-inch to 36-inch, 48-inch and 42-inch steel conductor casing jack and bores under UPRR main lines, rehabilitation, replacement and new construction of manhole structures, installation of a custom splitter box structure, abandonment of existing sanitary sewer interceptor pipelines and structures, and traffic control.The project required a maximum bypass pumping flow rate of 9.75 MGD during tie-ins and replacement of existing pipelines.
Farr West was utilized as a sub-consultant to design the associated sanitary sewer lift station site. Work included design of the interconnecting piping, wet well, submersible pumps, emergency storage, backup generator and other pertinent facilities and equipment.Lumos’ design and construction staff worked cohesively as a team to identify and resolve matters beforethey became problematic. Additionally, Lumos provided coordination between numerous entities,consultants and contractors; enabling a seamless project with multiple stages and complexities.
Challenges included working 24-hour shifts on Wells Avenue to accelerate the project schedule and minimize lost revenues to adjacent businesses. Timing of the completion of the gravity lines and force main was critical with the commissioning of the new lift station as flows were rerouted during design and had to be “temporarily” diverted until the lift station was operational.
Tony Angelopoulos, NDOT, “Wanted to thank Lumos and the City of Reno for their coordination efforts and the high quality workmanship on Wells Avenue. The project turned out great and the accelerated schedule and construction practices provided for minimal impact to the businesses and traveling public”

The awards are adding up for this groundbreaking project. In August 2013 we received the American Public Works Association (APWA) Transportation Project of the Year Award. In November 2013 we received the Engineering News-Record (ENR) award. What is next? We say more great projects like this one!
Eureka County’s short construction season forces some aggressive schedules on their engineers and contractors. The County’s demand for quality and accuracy requires everyone involved to be operating at the highest level. However, last summer brought a project whose schedule was so aggressive that it demanded an extraordinary effort from all involved.
Utilizing a grant from the FAA, the County set forth on a project, designed and bid by Lumos, to re-construct/re-profile the full runway, apron, and approach taxiways of the County Airport. All work activities had to be started after Memorial Day weekend and completed before the start of the wildfire season. In other words, the County gave Lumos 21 days to construct the $3.23 million project
Eureka County owns and operates the county airport located in Diamond Valley, about 7 miles north of the Town of Eureka, Nevada. The airport serves as a transportation link for the remote county by regularly receiving mining executives, refueling stops by aircraft passing through, and support for air operations for the local ranches. However, its most important function is serving MedFLIGHT and supporting air attack crews battling local wildfires. It is these last two that drove the requirement for minimizing the airport closure. Even with the closure, the airport construction operations were on constant alert for the potential of incoming aircraft. The readiness paid off because through the team’s preparation and constant communication, the closed airport was fully operable is less than five minutes of an incoming emergency call. In addition to two medical emergencies, the town of Eureka was also threatened by a nearby wildfire. The 2,800 acre Pinto Fire required multiple air attack operations with two type II helicopter crews and one fixed wing air command; all of which required multiple fuel cycles, staging of aircraft, and housing of crews at the airport during active construction operations.
This project included reconstruction of Runway 18/36, a 7,300 foot long by 60 foot wide ribbon of asphalt, connecting taxiways, and 73,500 square foot of apron. Construction specifications included pulverization of existing improvements, 7% cement treatment, and all covered with 3″ of FAA specification asphalt. The project progressed with pre-demolition and demolition operations taking place on one end of the runway, as the continuation of Cement Treated Base (CTB) and paving operations took place on the other. Pulverization and CTB operations of the runway allowed for nearly 100,000 square feet of demolition and prepared runway sub structure per day. Such vast quantities were accomplished by the utilization of three pulverization/CTB crews, two grade setting and grading crews.
In addition to providing the project design and bidding services, Lumos was also contracted by Eureka County Public Works, headed by Ronald Damele, to manage the construction phase of the project. The Lumos team consisted of Thomas Young, P.E. (Project Manager), Michael Bennett, P.E. (Construction Manager), Mitch Burns, P.E. (Geotechnical Engineer);Greg Phillips, PLS (Survey Manager). The construction contractor was Road and Highway Builders (RHB) and their key project leaders were Steve Blakely (Vice President) and Clint Madsen (Superintendent).
With constant oversight by key Lumos and RHB staff, construction operations ran like clockwork. With an average daily cost of approximately $150,000 and nearly 70 personnel working at the peak of the project, the final striping was applied and dry twelve hours prior to the required opening. In the end, RHB moved nearly 20,000 cubic yards of earth, mixed 1,400 tons of cement, placed 11,000 tons of asphalt, and hauled half a million gallons of construction water. As planned, the Eureka County Airport was opened on time, with zero safety incidents, zero change orders, and within budget!
Lumos provided design services that include geotechnical investigation, mapping and final plans and specifications for Units G & H of the City’s Neighborhood Street Rehabilitation Program. The contract involved the rehabilitation and/or reconstruction of 14 Neighborhood Streets, including but not limited to the replacement of the pavement sections, necessary removal of curbs and gutters, sidewalks, driveways, pedestrian ramps, catch basins, new storm drain improvements, pipe placement and other incidentals necessary to successfully complete the project. This project included extensive pedestrian connectivity issues and safety concerns along a section of Comstock Drive. Lumos worked with the City of Reno to evaluate feasible alternatives and associated costs. A retaining wall and guardrail were designed to provide a safe route for pedestrians, as well as a guardrail for vehicular safety.
This project won the California Transportation Foundation 2011 Pedestrian/Bicycle Project of the Year Award and the 2011 APWA Sacramento Chapter Best Transportation Project, $500k to $2 million category.
Lumos provided basemapping, alternatives analysis, preliminary and final design, and construction documents for 4,000 feet of recreational trail on the south side of the Truckee River east of the Town of Truckee. The trail traverses varied terrain including steep side slopes and dense trees, and is the latest phase of a proposed three-mile segment of trail. Several alignment alternatives were considered to minimize disturbance to wildlife habitat and extensive cultural resources. The project was complex due to the extensive cultural resources in the corridor and involvement from multiple agencies, including the Town of Truckee, the Truckee-Tahoe Sanitation Agency, the Truckee Sanitation District, Caltrans, the U.S. Forest Service, and the Lahontan Regional Water Quality Control Board.
Lumos provided design, plans, specifications, bidding assistance, consultant coordination, inspection and materials testing for this project. The project replaced a World War II-era facility and included a newly designed and constructed 160’x80’ metal building with two mezzanines, a brick façade, training room/kitchen, restrooms, storage areas, and six fire apparatus bays, along with concrete retaining walls, site utility upgrades (water/sewer), a parking lot, street improvements, and minor landscaping. Working with the County and other consulting engineers, Lumos had primary responsibility for ensuring preparation of complete sets of construction drawings. Lumos provided construction management, including special inspection, review of contractor submittals, change order proposals, and pay requests, and responses to Requests for Information.
The 800-student Silverland Middle School is located on an approximately 31-acre site. The design and construction schedules on this $22 million project were very ambitious, as the scope of work included the building site, athletic fields, parking areas, several public streets, and all utilities; a 600-student elementary school will be added in the future. Lumos provided planning, surveying, geotechnical investigation, hydro-logic and hydraulic analysis, site development, landscape architecture, materials testing, inspection, and construction assistance. The design team implemented many sustainable features: landscaping that utilizes drought-tolerant plantings and large shade trees over walkway and parking areas; grading with low-impact-development design elements; an array of small wind turbines to meet part of the electrical demand; and solar panels, utilized to heat the building. Coordination among team members has been crucial due to the complexity of all the systems involved.
