Glenn,

Subject: PROJECT SCHEDULING EXPERTISE

I am writing to express my appreciation for your services to dsi over the past year.

As a small organization, we find it necessary to supplement our staff in providing scheduling support

to our clients from time-to-time. Your schedule review and analysis, delay claim review, and

schedule development has proven invaluable to dsi in these instances. Your expertise and

experience in a number of areas within our industry represents the thoughtful, informative, and

quality client experience for which dsi has become known in our industry.

In addition, your willingness to respond quickly and with little direction or oversight provides

significant value sometimes lacking in consultant services.

Again, thank you for your support. I look forward to continuing to work with you in the future.

Please feel free to use this letter or my name as a reference in the future for Primavera scheduling

services.

Best,

President
