Preventative Maintenance Project

Preventative Maintenance Project, Washoe County, RTC

Project Description

Since 2003, Lumos has 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 years of 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 projects schedules, special events etc. within our surface treatment area. Daily coordination occurs between 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.
