SUBJECT: 2001 PAVEMENT DEFLECTION TESTING
CAO RECOMMENDATION
Authorize the CAO to award a contract via purchase order to Chec Engineering Consultants for
2001 Pavement Deflection Testing in the amount of$17,880.
DISCUSSION
Staff is currently working on the Plans and Specifications for the Street Reconstruction and
Resurfacing - Summer 2001 paving project. In order to complete the plans staff needs pavement
deflection testing to be completed. Pavement deflection testing measures the strength of the
existing pavement, and is an important component of the design process. Testing is preformed to
ensure that the thickness of the new asphalt overlay will last for the entire design life of 20 years.
Proposals were solicited for this years' pavement deflection testing project from three well-known
consulting firms that perform this service: Chec Engineering Consultants, Pavement Engineering,
Inc., and Nichols Consulting Engineers. Each of these consulting firms responded with similar
proposals to do this work. The proposal by Chec Engineering Consultants was for the lowest dollar
amount($17,880), and is the consultant that staff wishes to perform this work.
The City's purchasing guidelines require that if consultant work is between $5000 and $15,000,
proposals be solicited in a practical manner. If the consultant work is.expected to be between
$15,000 and $50,000, then a formal Request for Proposals (RFP) is required. Based on past years'
experience, staff had expected this consultant work to cost between $5000 and $15,000. With the
lowest proposal showing a cost slightly higher than the $15,000 limit, staff cannot simply award the
contract with a purchase order. In this case, action by the City Council is required.
CONCURRENCES
A Notice of Exemption has been filed with the Community Development Department for the
construction of the Street Reconstruction and Resurfacing - Summer 2001 paving project.

Nichols Consulting Engineers $25,508
Amount Available in Budget $829,000
ALTERNATIVES
The Council could require that staff proceed with a new formal RFP to do this Pavement Deflection
Testing. This process would be much more time consuming and could delay the start of the paving
project. This is not recommended due to the fact that paving projects tend to be more successful
when done during the warmer time of year prior to the rainy season.
