I wanted to take this opportunity to send you and your firm a letter of reference.
Thank you for your exceptional service and work over the past year. It is a real pleasure to
work with a company such as yours that is so professional, reliable and accommodating.

This letter confirms that Heninger Structural Engineering Ltd has completed numerous
projects for us in the past. All work to date has been of high quality and completed
expeditiously in a professional manner.

We have used Heninger to provide all of our Steel Stud Shop Drawing since 2005. I find
Jim and his staff very easy to deal with and would not hesitate to recommend them.

Just a brief note to thank you for your professionalism in the structural engineering
redesign of a couple of Facility Operation's projects for the City of Calgary (Alberta
Trade Centre and the Manchester Building R Fleet Services).
