Since 2003,Lumoshas provided project scoping including roadway condition analysis which includes existing surface evaluations, determination of asphalt cracks for width and depth; asphalt patching requirements; videoing using GoPro cameras for use during design of existing striping and patch lay-out along with treatment recommendations as part of the Washoe County RTC’s Annual Maintenance Program. Our team’s approach to this project is a coordinated effort with all parties involved including the Washoe County RTC, City of Reno, City of Sparks, Washoe County and the Nevada Department of Transportation.Upon completion of the project scoping, Lumos identifies roads that need to be completed within that year and ones that could be delayed. Those lists are forwarded to their respective agencies for review, comment and acceptance. Many times, a field meeting will be required to meet face to face to achieve everyone’s goals. Once the final list is approved by all parties, a determination of patching limits in the field is completed and once again coordinated with all agencies involved to verify Lumos’ patching limits.Once approved, Lumos maps the areas for patching, crack seal and slurry quantities and utility valves by utilizing GPS/GIS technology. Prior to advertising for bid, the proposed final maps and specs are sent out to all parties for a final review and a final request for changes including adding/deleting striping, the addition of bike lanes, dropping lanes, etc. Once the final comments have been received, Lumos prepares digital plan maps that are incorporated into the contract documents along with technical specifications. The digital plan maps depict patch location and size; utilities; slurry limits and quantities; and striping details.
The project deliverables have improved over the years from a simple set of specifications with a spreadsheet of the proposed slurry streets and quantities to what it is today - maps depicting patch sizes and slurry limits. In the early yearsof the project, the use of traditional slurry seals was used exclusively throughout the region, however after discussions with the local agencies, the decision was made to move to micro-surfacing which cuts the impacts to residences, businesses and the general public due to quicker set-up times. A few years ago, Lumos began to implement a “Cape” seal program to prolong the wearing surface for roads located in the Lake Tahoe Region, namely Incline Village. This allowed for heavily plowed roads to still last 5-7 years before having to re-surface treat.
Lumos has also provided construction inspection, materials testing, contract administration, public relations and interagency coordination for this project since its inception in 2003involving over 200 million square feet of roadway surface treatments, including Type 2 and 3 microsurfacing, Cape Seals, asphalt patching, crack sealing, pavement striping and markings, and traffic control. Public relations and project coordination with multiple agencies has been and will continue to be key for the success of this project. Coordination with the local owning agencies saves time when it comes to other construction projectsschedules, special events etc within our surface treatment area. Daily coordination occursbetween the Washoe County RTC, City of Reno, City of Sparks, Washoe County Public Works, NDOT, RTC Ride. Coordination with all parties is key to keeping projects like these moving forward while minimizing impacts to the general public, adjacent owners, schools and hospitals
The Roop Street Annex Building Project consists of the demolition of an existing salt barn and the site work for the construction of a new office building that is approximately 18,900 square feet. NDOT contracted with Lumos &Associates to provide the quality control and testing of the earthwork, concrete, masonry and special inspections. The building is a masonry split face block construction with a concrete slab on grade which includes a data room, fire sprinkler room, utility room, break room and restrooms. The front of the buildingconsists of store front glass windows.
Lumos provided a geotechnical investigation, site utility location, materials testing, special inspection and survey services for the construction of a new 27,107 square foot fitness center at NAS Fallon. The fitness center replaced 3 older buildings that were currently utilized at the NAS Fallon’s fitness center andwill contribute to the retention, readiness and mental, physical, and emotional well-being of the active duty, reserve and retired personnel by providing a varied program of recreational, social and community support actives. It is pending LEED Silver certification and the final cost was approximately $9 million. The facility includes indoor basketball, volleyball, and racquetball courts; fitness areas, multipurpose activity rooms, locker rooms, storage rooms, reception counter, administrative offices, and a laundry room. As part of Lumos’ services, the following were provided: construction staking for the building and site, site utility location, monitoring of settlement monuments installed within the structure, materials testing, special inspection and as built surveys of final drainage improvements.
Utilizing a grant from the FAA, Lumos provided design and construction management for the reconstruction of Runway 18/36, connecting taxiways, and 73,500 square foot of apron at the Eureka County Airport. The project totaled $3.17 million and was built within 21 days to meet closure requirements set forth by the County. Construction specifications included pulverization of existing improvements, followed by 3" of FAA specification asphalt on 7% cement treated base. 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. The contractor 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.
The I-580 freeway extension between Reno and Carson City has been “on the books” in one form or another since 1957. This new segment extends the freeway from the Mt. Rose Highway (State Route 431) to the Bowers Mansion cutoff, completing the freeway in southern Washoe County. The new roadway includes nine bridges and 8½ miles of freeway, winds through remote canyons in Pleasant Valley, and involves numerous unique features, including the longest, highest arch supported bridge in Nevada. NDOT Contract 3292 also includes sculpting of the rock cuts, revegetating slopes, and construction of retaining walls on the downhill slopes. Due to the high winds and safety concerns voiced by the prior contractor, Fisher Industries decided to use a different approach to build the arch at the Galena Creek Bridge. The decision was made to temporarily fill Galena Creek Canyon to a maximum height of 140 feet and build the arch on top of the temporary fill. The fill was approximately 210 feet wide at the top and 385 feet wide at the base of the creek. In order to construct the fill, Fisher had to move 380,000 cubic yards of material. Once the fill was in place, falsework was built on top of the fill to support the arch during construction. A temporary culvert was constructed to allow Galena Creek to pass under the temporary fill. Lumos served as a subcontractor to primary contractor Fisher Industries on this contract. Lumos provided ageotechnical investigation, expert analysis, materials testing, construction inspection, and concrete mix design testing on this $393 million dollar contract. Our Geotechnical Engineer, Mitch Burns performed the geotechnical site investigation and recommendations for foundation of the arch structure and earth fill. He also provided QA/QC during the construction of the temporary fill to assure settlement would be maintained within allowable limits.Construction Services Engineer, Mike Brown assisted Fisher Industries by providing the High Performance Concrete mix design for the bridge decks for this project including the Galena Creek Arch Bridge.
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.
