Attached is a copy of the agenda for the subject meeting, which will be held on Monday, February 5, 2007, from 1-5 pm at the Tropicana Hotel in Atlantic City, New Jersey. This will precede the annual Mid-Atlantic States Quality Assurance (QA) Workshop, which will be held at the same hotel from February 6th to 8th. It is highly recommended that participants at the PCEF meeting also attend the QA Workshop. Please note that registration is not required for the PCEF meeting, however, it is required for the QA Workshop. Attendees are asked to check the website www.midatlanticqaw.com for details about the Tropicana Hotel and the QA Workshop. When registering with the hotel, please use the code “HNJDOT7” in order to receive the conference room rate.

Members with an Internet address will receive these materials electronically. Hard copies will not be mailed to these individuals. Members without an Internet address who have an ‘**’ next to their name will receive a fax of the materials. All recipients of these materials are requested to make the information available as soon as possible to other non-Internet members in their State or Company.

Attached are copies of brochures announcing two concrete-related conferences for 2007. The first is the “Concrete Technology Forum,” with additional information found at www.ConcreteTechnologyForum.org. Next is the “First International Conference on Recent Advances in Concrete Technology.” Members are encouraged to register for these very worthwhile conferences; and there is still time to submit an abstract for the second one.

An example of voided slab design using the Load and Resistance Factor Design method has been developed by the Virginia Department of Transportation. It has been posted on the Central Atlantic Bridge Associates website, located at: http://www.caba-bridges.org/PCEF/PCEF_D.aspx. The example may also be viewed at http://www.midatlanticqaw.com, under the PCEF section.

We look forward to another successful turnout and to the active participation of all members at the meeting. In particular, State DOT attendees are requested to come prepared to discuss follow-up actions taken in regard to agenda items 7, 8 and 9.
