Peggy Ganse Earns Tunnel Inspection Certification
January 25, 2016

Shannon & Wilson’s Senior Tunneling Services Project Manager, Peggy Ganse, P.E., P.G., recently obtained National Certified Tunnel Inspector (NCTI) certification to perform safety inspections of tunnels nationwide. Ganse attended training provided by the National Highway Institute (NHI) of the Federal Highway Administration (FHWA) and earned the certification under NHI’s new NCTI program.

In July 2015, FHWA established new National Tunnel Inspection Standards (NTIS) for highway tunnels. This NCTI certification is now required for inspection of all tunnels on public roads and on and off Federal-aid highways. All key elements of highway tunnels are covered under this program, including structural, civil, mechanical, fire/life safety/security, and electrical and lighting. 

Ganse is a geologist and geological engineer with 23 years of experience designing, managing, and performing geotechnical services for tunneling projects across North America. As nationally-recognized experts in tunneling and underground services, Shannon & Wilson has performed tunnel work for railroad, utility, and transportation clients for more than 60 years.

Senior Vice President and Denver Office Manager, Greg Fischer, stated, “We are excited to have NCTI certification as part of our condition assessment capabilities. It will allow us to better serve our clients by guiding them through the NTIS requirements and regulations. It also serves as another tool to help our clients with the important task of asset management.”
