Preconstruction honored with regional quality award

UDOT Region Four’s Preconstruction Team has developed GIS tools that support and enable communication and better decisions, and charts a path for other work groups at UDOT to exploit GIS capabilities more fully.

The team won a WASHTO award recently for developing and employing GIS tools. Here’s an overview of some of the team’s efforts. Click here to read the full WASHTO award nomination.

GEO-referencing design files

A Design-to-UPlan app displays the design files on a UPLAN map. Multiple design options can be displayed to facilitate discussion among UDOT and stakeholder groups. All three phases of a project, concept, plan-in-hand and PS and E, can be viewed simultaneously on one screen with multiple windows.

Mapping right-of-way survey files

The team has also built tools to convert Right-of-Way (ROW) survey data from CAD to GIS, and graphically display the UDOT ROW lines on a UPLAN map. Certified section corners, complete with tie sheets, are also linked to the map and accessible to the public. A ROW Type Map app displays property in one of three categories, ROW, Limited Access or No Access.

A pilot project, when fully implemented, will pull information from ePM each evening, and display individual parcels within a project area on a UPLAN map. The parcels will be color-coded to show the acquisition status of each parcel. Hosting the maps on UPLAN allows public access with security controls to insure the integrity of the data and to regulate sensitive information.

Mapping utility conflicts

By displaying utility data and infrastructure via UPLAN, project teams can work to quickly resolve potential conflicts with utility companies. Ultimately, Region Four’s vision is to create a database of all utilities within the region and statewide.

Mapping sensitive environmental areas

Region Four Preconstruction has been working with the State Historic Preservation Office to develop protocol to ensure the secure use of sensitive environmental data.  The team also standardized a GPS data dictionary for use in managing mitigation for Utah Prairie Dog surveys.

GIS tool benefits

GIS tools provide value to project teams and stakeholders. Maps help solve communication gaps among disparate groups, including the general public, commercial land surveyors, land owners, policy makers, and contractors. For example, UDOT Project Managers can help local leaders and the general public visualize project options and outcomes, and help facilitate a better decision-making process. And sharing an online map can allow productive work sessions with participants in various remote locations.

GIS maps and apps can support complex environmental processes. Region Four is home to most of Utah’s cultural sites and threatened and endangered species, and GIS tools help UDOT staff reduce or mitigate protected areas and avoid animal habitats.

While GIS has a sophisticated infrastructure, Region Four’s Preconstruction department has embraced the new technology to understand and develop its capabilities and has pioneered GIS tools for the benefit of all of UDOT.

Congratulations to Region 4 Preconstruction!

GIS tools at work in UDOT Region Four

UDOT Region Four takes in half of the state. While other regions face heavy snow or urban traffic, Region Four’s challenge is to coordinate work over a large area. Geographic Information System (GIS) tools have helped that coordination process.

The following post is the first of a two-part series about how GIS tools help employees expedite work and refine the quality of information needed to improve the transportation system.

Data Portal screenshotGIS data can be accessed at the UDOT Data Portal.  Much of the information on the site is geo-referenced – that is, given an exact spatial location. The UDOT Data Portal also has tools to view and analyze the data sets. Tools include maps and the Linear Bench, a straight line diagram generator. Both tools can be populated with multiple data sets, like the location of culverts or bridges. Data sets can also be downloaded.

Maps and apps improve work coordination

The Utah Prairie Dog, which occupies habitat within the right-of-way of many highways in Region Four, is afforded protection under the Endangered Species Act. UDOT recently completed a formal consultation with the US Fish and Wildlife Service that defined measures to minimize impacts to this species.

As part of implementing these measures, UDOT uses GIS and GPS tools to identify and quantify the acreage of habitat of temporary and permanent impacts. The tools expedite surveying and monitoring efforts so UDOT can quickly complete necessary road work.

Material pits are the sources of rock, sand and gravel used on construction and maintenance projects. Pits located on BLM or US Forrest Service land require permits.

An app that geographically displays the pits along with their permitting information is helping UDOT employees stay on top of the permitting process. The app generates an automatic email six months before expiration of the permit so UDOT won’t risk losing access to pits.
