Subcontractor of the Year - 2011  

 US Steel: Gas Line Repair
 Installation of Steel Sheet Piling and Bracing
 Gary, Indiana
 
As a subcontractor to The American Group of Contractors (TAG), Thatcher Foundations Inc. safely completed 586.5 manhours under the NMAPC on this sheet piling and bracing project. Thatcher's earth retention design provided stabilization for the adjacent railroad embankment. After Thatcher's employees from Local 578 Pile Drivers, Indiana Local 150 Operators and Indiana Local 142 Teamsters were mobilized to the jobsite, field conditions necessitated a change of plans. A previously unknown pipe crossing was discovered during excavation, requiring Thatcher's in-house engineers to alter their design. The drawings were revised, and the project continued, allowing for a successful repair.

Thatcher was able to mobilize quickly to this nitrogen leak repair project, because Thatcher maintains an "A" rating with US Steel through ISNetworld's safety evaluation system. The unusual working atmosphere required each employee to wear an individual air quality monitor, and welders and burners had supplied air. Each Thatcher crew member, including the supervisor, had 40 Hour HazMat training, and had previously completed confined space training.
