Mr. John Langer,

This is to commend your firm for the quality performance provided to us over the past few years. On numerous of our Capitol Campus projects, we have benefited from your check estimates, constructibility reviews and cost estimating services.

Your ‘check estimates’ on some of our projects of the A/E cost estimates has alerted us to potential cost overruns prior to bid-release and we were able to negotiate appropriately and ultimately bid out these projects within budget.

Your constructability reviews and plan reviews have been extremely beneficial for some of our projects because of the potential errors, omissions, and value recommended changes you were able to find and offer in the document development stage prior to release which we are confident has saved us much by eliminating potential change-orders.

Your responsiveness and toughness to assist with the emergency earthquake analysis and costing effort is very much appreciated.

The diverse professionalism, responsiveness, and technical accuracy of you and your firm will assure that we  continue to do business with you well into the future.

With Appreciation,

– Gary Larson

This is a letter of recommendation for John Langer Consulting. They have provided us with cost estimating, construction document quality control and constructability reviews. We have worked with them consistently for the past five years and are very pleased with their services. Our main contact has been with John Langer, Principle.

The projects they have assisted us on range from the 1600 square foot Watershed Education Center at the Issaquah Hatchery, Conceptual Design for Camp Muir above Paradise in Mt. Rainier Park and the new Jaguar Exhibit at the Woodland Park Zoo. Regardless of the size or complexity of the project we have always received concise and intelligent information regarding quality control and constructability. The cost estimates have been accurate and tuned to the current market conditions and unique project configurations or locations. Services have always been delivered in a timely manner for the agreed upon fee. I highly recommend John Langer Consulting.
