NAT 2020

The North American Tunneling Conference

June 7-10, 2020
Gaylord Opryland Resort & Convention Center
Nashville, Tennessee, United States

Hatch is pleased to announce that we will be presenting and exhibiting at the North American Tunneling Conference (NAT) from June 7-10, 2020, at the Gaylord Opryland Resort & Convention Center in Nashville, Tennessee, USA. Hatch will be exhibiting at booth #1104.

NAT is the premier biennial tunneling event for North America, bringing together the brightest, most resourceful, and innovative minds in the tunneling and underground construction industry. This four-day conference focuses on the information, advances, and projects in North America along with the victories and challenges of working in diverse environments. It’s the place to be this June if you’re in the tunneling and underground construction industry!

Hatch will be represented by:

  • Dan Ifrim - Tunnel Cost Estimating – Sharing our Experience   
    Tunneling is a high-risk and challenging industry, with construction methodology decisions based on cost, technical considerations, and social impacts. This presentation will discuss the use of construction cost estimating tools and their applicability and accuracy for estimating tunneling works, specific estimating tools strictly used for tunneling and underground cost estimates, the importance of estimating tool customization, and the importance of understanding local market conditions.
  • Dan Ifrim - Nose Hill Water Supply Tunnel Design                                    
    The City of Calgary is constructing the Nose Hill Water Supply Tunnel using tunneling technology, open-cut methods, and trench-less crossings of major roadways. This presentation will discuss the aspects and challenges of tunnel design in variable ground conditions.
  • Don Del Nero - TBM Hardening & Anti-Wear Implements Against Ground Abrasion                                                                                            
    The impacts of abrasion must be considered holistically for all TBM types and their individual components including, but not limited to, shield design, spoke type, panel/plate type, other cutterhead-facing elements, cutter mounts, structural joints, muck scoops, muck shoots, conveyor belts, conveyor rollers, plenum chamber design, screws, screw conveyor casing, slurry pumps, slurry pipelines, and overall muck flow path. This presentation will highlight relevant metallurgical principles as applied to TBMs, common TBM wear patterns, customized anti-wear mechanisms used, custom steel alloys in the market and where they have been implemented, and various configurations of anti-wear hardening.
