New Plant
Hartford, IL

Dear Mike:

I would like to take this opportunity to congratulate you and your firm for your outstanding performance on the above referenced project.

As you know, the project was very complex. The scheduling of the pile driving, rebar installation, and structural concrete required superior planning efforts to maintain progress while never sacrificing the safety programs as established by both BOC Gases and RCS Construction, Inc.

The project’s schedule required a second shift for successful completion. Your firm exceeded in both the management and field personnel provided on the jobsite.

BOC is very pleased with your professional performance, your excellent safety record, and the quality of workmanship.

We look forward to an ongoing relationship on future projects.

Sincerely,

BOC GASES
Dick Cornelius
Project Manager
