Attached for your information is a copy of the attendance list and minutes from the subject meeting, held on August 29, 2006 at the Maryland State Highway Administration’s District Office in Buckeystown, Maryland. Also attached are copies of the full PCEF membership address list and subcommittee membership lists for your review.

We wish to thank Mr. Waseem Fazal of the Delaware Department of Transportation, for his outstanding job of taking notes at the meeting and completing the minutes in a very timely manner. Minutes, lists and all other attachments referenced in the minutes will be posted on the FHWA Resource Center’s High Performance Materials website at: www.fhwa.dot.gov/resourcecenter/teams/structures/hpm_pcef.cfm. The link is located in the Structures Team section of the Resource Center website, under “Solutions,” where there is a section on High Performance Materials. PCEF is listed under that section. The materials are also posted on the link referenced in the minutes for the Central Atlantic Bridges Associates.
Those members without an Internet address who have an “**” next to their name will receive either a fax or hard copy mailing of the materials. All recipients of these materials are requested to make the information available within your offices to other non-Internet members on the PCEF list. Problems with receiving copies by fax or mail may be addressed to Ms. Noni Brown of our office (410-962-7965) or firstname.lastname@example.org.
The attached minutes are supplemented as follows:
Agenda Item #6 – Materials & Construction QC/QA Subcommittee
Action Item: FHWA and State DOT representatives are encouraged to work together to implement the adopted Quality Control Requirements ballot item, as an appendix to the PCEF “Specification Guidelines for Precast/Prestressed Concrete Bridge Products.”
Agenda Item #10 – Other Issues: Delayed Ettringite Formation (DEF)
Action Item: State DOT representatives are encouraged to visit the website noted, and to discuss with appropriate personnel within their Departments the possibility of participating in the proposed pooled fund study.
Agenda Item #10 – Other Issues: Tall Pier and Elastomeric Bearing Design
Action Item: FHWA and/or State DOT representatives are asked to provide to us by January 15, 2007 responses to questions listed for this subject.
The August 2, 2006 FHWA Weekly Report highlighted the dedication and ribbon-cutting ceremony for the Lord Delaware Bridge, Route 33 over the Mattaponi River in Virginia. The $37.6 million bridge has the largest and longest prestressed concrete spliced haunch bulb tee girders used in the State, with two units of 200’-240’-240’-200’. All of the approach spans incorporated Virginia’s adoption and use of the PCEF bulb tees. All spans over 125’ were built using lightweight HPC in the girders and bridge deck. The State is to be congratulated on its progressive use of these new technologies.
A TS&L preliminary design publication is currently being prepared for the Portland Cement Association. It will include information on the PCEF bulb tee shapes adopted by the Mid-Atlantic States, as an example of the new generation of shapes that started with Nebraska’s NU I-girder about 15 years ago.
Attached are minutes from the June 2006 meeting between the northwestern State DOTs and the PCI northwestern region of producers. The minutes cover design, construction and research issues that we believe will be of interest to the PCEF subcommittees and general membership.
Attached is a copy of a brochure announcing the “First International Conference on Recent Advances in Concrete Technology.” Members are encouraged to submit an abstract for paper presentation, and to register for attending this very worthwhile conference.
We are scheduling the next PCEF meeting in conjunction with the annual Mid-Atlantic States Quality Assurance Workshop (QAW), which will be held at the Tropicana Casino and Resort in Atlantic City, New Jersey, February 6-8, 2007. Our full Committee meeting will be held on Monday afternoon, February 5th, from 1-5 pm at the hotel. Attendees for both meetings are asked to check the website for details about the Tropicana and the QAW.
We highly recommend that attendees for the PCEF meeting also make plans to attend the QAW. This is an excellent annual venue with a breakout session devoted to concrete issues. Please note also that vendors will be allowed this year at the QAW.
Once again, we thank the membership and their management for the support of this Committee’s activities. Please feel free to submit agenda items for the next meeting by December 15, 2006.
