SWIFT Contract Number 3000039522/3000076040

Project Name Development of a Weigh-Pad Based Portable WIM Syst

Project Number (if applicable) 89261 W114

Summarize purpose of the contract, including why it was necessary: Monitoring truck weights on local roads has become more important in recent years as the number of trucks supplying materials for bio-fuels increase. Since local roads are not designed to carry heavy trucks like the interstate roads are, even a small increase in truck volume can drastically shorted the pavement life span. On the other hand, monitoring truck weights using permanent weigh stations is very expensive and not justifiable for local roads. The proposed weigh-pad based portable WIM approach provides a solution for monitoring truck weights on local roads.

Evaluate the contractor's timeliness The system was delivered in a timely manner. Prof. Kwon adjusted his schedule when the state shut down and provided a demonstration of the product after we came back to work in July of 2011.

Evaluate the contractor's quality The system is very user-friendly and he quickly incorporates our comments. We evaluated a large pad with two sensors in it but it would be too heavy to be practical in the field. He consulted with the TAP and we came to a quick decision to go with two separate sensor pads.

Evaluate the contractor's cost His costs are very reasonable. He is the definition of “Best Value.”

Evaluate the contractor's overall performance Prof. Kwon always delivers a very good product. He reacts quickly to any requests we have for changes. He produced a field-ready, user-friendly, durable device.

Would you engage the contractor's services again? Yes

Describe any negative action taken during the duration of this contract (i.e., termination, pursuit of suspension, etc.): {Empty}

Please rate the overall experience with the contractor 5 - very satisfied
