Topic: Overview of Subsurface Utility Engineering and ASCE 38 Standard Update

Speakers: Buck Wright & Aidan Deegan, T2 Utility Engineers

Subsurface Utility Engineering (SUE) is a non-destructive engineering process that combines civil engineering, geophysics, surveying, mapping, and asset management technologies to collect and manage existing utility information. The goal is to minimize risks associated with underground utilities during construction projects. The quality level used in SUE services determines the level of risk assumed by the project owner or engineer. The original ASCE 38 standard was published in 2002 and the updated version aims to provide guidance based on 20 years of experience and technological advancements to inform risk-based decision making by licensed professionals.

Topic: NDOT Tactical Urbanism Guide

Speakers: Lauren Gaines Barge Design Solutions & Justin Cole, Nashville MTA

In a world of quick fixes and temporary installments, cities around the world are looking for a means to development and implement goals related to public space, street safety, community enrichment, and more. Within the recent years, a name has been developed for this effort, Tactical Urbanism.

In 2022, the Nashville Department of Transportation (NDOT) decided to develop a Tactical Urbanism Guide. The city has a rich history with parklets, grass roots transportation efforts, OpenStreets events, and much more. The department contracted with Barge Design Solutions, and a team was formed to review peer cities, develop a Best Practices Review, and host stakeholder meetings for key organizations (such as Metro Arts, Metro Parks, the Civic Design Center, NDOT Vision Zero, etc.).

After the stakeholder meetings are held, a Tactical Urbanism Guide will be produced from the Best Practices Review and the key stakeholder feedback. A formal Tactical Urbanism Guide will encourage more safety and community transportation improvements by locals and community organizations. It will also provide project standards and a rough outline for participants interested in implementing these projects, including who they should contact to begin the process.

To date, the best practices review is underway. It is anticipated to be completed in February of 2023.
