360-degree Point Cloud photography and reconnaissance drones to ID and resolve facilities problems

Office of Maintenance Building Services Section is proposing to test the use of a 360-degree Point Cloud camera for internal and external facility use as well as a reconnaissance drone for external facility inspection at several key locations. These two technologies would be used in tandem to evaluate the condition and performance of our facilities building systems, from exterior envelope (roofs, siding, doors, walls ...more »

Why is this a priority and what are the benefits for the State/County/City? :

This is an opportunity to determine if the use of this technology would be beneficial for a statewide application. There are 137 truck stations and 18 district headquarter sites where this technology could eventually be used. Benefits to users, and hence the State, would include time and travel cost savings from not having to visit sites to resolve issues. This is especially important when responding to immediate building concerns requiring interaction between district or special service personnel and Building Services staff, as well as contractors.

Unmanned Aircraft Systems (UAS) - Pond and Stormsewer Inspection and Data Collection

MnDOT Metro District has over 600 stormwater ponds to manage. Unmanned Aircraft Systems (UAS) have proven beneficial for the inspection and maintenance of bridges. Could the same technology be used to assist Metro District in the management of these ponds? The ponds tend to be very difficult to survey. Most are overgrown with vegetation and to survey pond bottom a boat is required. We would like to develop a ...more »

Why is this a priority and what are the benefits for the State/County/City? :

The costs for sending a survey crew to a pond site, the costs associated with launching a boat and doing soundings of the 60 ponds would cost roughly $250,000. However, many of our ponds are adjacent to freeways and safe access is a concern. Traffic control may be necessary to safely survey the ponds. To be able to collect this information in a safe fashion with the minimum impact to the traveling public is a very big benefit.

Idea Champion - Who at MnDOT/LRRB? : Joe Huneke

Why is this a priority and what are the benefits for the State/County/City? :

Current passive road sensors are imbedded in the road surface. Whenever there is a construction or maintenance project that impacts the road surface (mill and overlay, sealcoating, patching, etc.), the imbedded sensor must be replaced. This, and periodic RWIS site and sensor maintenance, requires lane closures and cutting the road surface to install the sensor and cables. The non-invasive sensors are attached to the RWIS tower or a pole near the roadway and uses laser technology to read the road surface temperature and condition; subsequently, future road projects do not impact the sensor and periodic maintenance does not require lane closures.

Implementation of Wet or Soft Soil Crossing Technology

Maintenance and construction operations need to cross and stage over wetlands or low bearing capacity soils to perform necessary state work. Various permits require wetland avoidance or minimization of impacts. Additional environmental commitments include minimizing or preventing soil compaction, preservation of soil function and structure, preservation of the native plant community, preservation of soil habitat for ground ...more »

Why is this a priority and what are the benefits for the State/County/City? :

Priority to allow maintenance to perform all-season work operations and construction to stage within restricted footprint, regardless of equipment type. The benefits are temporary work in wetlands and other soft soils that prevent compaction, allow winter tree removal for endangered bat avoidance, repairs to noise walls and other infrastructure in wet areas. This has statewide benefits for all road authorities for construction and maintenance of the infrastructure, regardless of season and soil type and will enhance financial effectiveness by allowing both work and meeting environmental commitments..
