While the tunneling industry has done a good job of embracing the concept of the geotechnical baseline report (GBR), this positive development is undermined to a certain extent by a general misunderstanding of what constitutes a challenging vs. easy dewatering condition.  Written by Chief Dewatering Engineer Greg Landry, P.E., this informative article describes how a deeper understanding of the interaction between the dewatering system and the site geology can lead to improved geotechnical baseline parameters relating to dewatering.

Moretrench’s Six Bridges Micropile Project Featured on the Cover of Foundation Drilling Magazine

By | News | No Comments

Shortcourse

Micropile foundation systems were installed to replace existing abutments and piers for roadbed upgrade at three bridges along the Saw Mill Parkway in Westchester County, NY. The project was completed under the $40M Region 8 Bundles Bridges Design-Build Contract, part of an overall New York State  Scour Critical/Flood Prone Bridge Program. Where the Parkway runs beneath two low overhead historic stone arch river bridges supporting local traffic routes, a 2-lane span of the 4-lane roadbed sits atop columns founded in the water, effectively creating a bridge beneath a bridge scenario. The complexities involved in installing the micropiles under the restrictive site conditions and within a limited timeframe is discussed by Frank DiSalvo, Project Manager for specialty geotechnical contractor Moretrench, and Stephen Mascia of General Contractor ECCO III Enterprises.
