MID-ATLANTIC STATES STRUCTURAL COMMITTEE FOR ECONOMIC FABICATION MEETING (SCEF)
MID-ATLANTIC STATES STRUCTURAL COMMITTEE FOR ECONOMIC FABICATION MEETING
FEBRUARY 11, 2003
HOLIDAY INN CHARLESTON HOUSE
CHARLESTON, WEST VIRGINIA
1. Introductions and Opening Remarks
Mr. Lou Triandafilou of the
FHWA convened the meeting at 8:00 AM. The participants were welcomed and
asked to give a self-introduction. A copy of the current mailing list
was circulated among the attendees and they were asked to verify the information
and make necessary corrections. Copies of the current Subcommittee lists
were also distributed, with a request that attendees volunteer to serve
on appropriate ones.
An announcement of the untimely passing of Mr. John Brunell was made and
followed by a moment of silence. John was employed by the West Virginia
DOT in the Structures Division and was a very active member of the group.
Mr. Triandafilou noted that
this year we were meeting in conjunction with the 36th Annual Mid-Atlantic
States’ Quality Assurance Workshop. Discussion that followed indicated
that this was a good idea and should be repeated on an annual basis.
2. Approval of Minutes from April 3,2002 Meeting in West Atlantic City,
Mr. Triandafilou asked if there were any additions or deletions to the
minutes from the April 3,2002 meeting held in West Atlantic City , NJ.
A motion was made, seconded
and carried to accept the minutes as written.
3A. AISC Task Force on Minor Bridge Component Certification
Ms. Anna Petroski from Quality
Management Company, LLC gave an update on the status of the Minor Bridge
Component Certification Program she is developing for AISC. The certification
has been changed from a line-by-line checklist to a standard format. The
program will include QC/QA provisions and a core quality management system.
Some of the components covered in the certification were bridge railings/barriers,
bearings, drainage assemblies, grid decks, walkways, expansion joints,
overhead sign supports and piles.
Two suppliers have volunteered as beta test sites for the new program,
with audits to begin this June. Overall, the program is anticipated to
be more economical for suppliers of the above items, rather than going
through the Simple Bridge Program.
(Note: As follow-up to this
discussion, Anna has scheduled a meeting of the Component Task Group,
to be held the afternoon of May 13th in Portland, ME. This will precede
the meeting of the National Steel Bridge Collaboration, where the draft
document is scheduled to be presented.)
3B. Standardization of Design/Fabrication of Overhead Sign Supports
Mr. Tom Macioce with PADOT
gave an update on the results of the survey that the SCEF Sign Task Force
conducted. Items addressed on the survey were welding code; CVN requirements
for pipe chords, gusset plates and base plates; electronic shop drawings,
and general discussion. The states that responded to the survey were PADOT,
NJDOT, MDSHA, DELDOT and VADOT. (Note: A copy of the completed survey
The following items are to
be discussed at the next task force meeting: column base plates, bolted
truss connections, welded pipe-to-pipe connections, sign attachment to
chords, and design Issues.
As an additional point of information,
it was noted that Valmont Industries recently held a meeting with the
Oklahoma DOT to discuss implementation of the AASHTO 2001 Design Specifications
for Sign Supports, etc. Issues included the following: size and cost of
members designed using this code will nearly double, due to fatigue considerations;
most states have not implemented the 2001 code; the ConnDOT had an overhead
sign failure, and as a result, reversed their position to adopt the Specification.
The Chairman asked for volunteers
from MDSHA, NYSDOT, VADOT or WVDOT to assist OK DOT in a review of their
state program. The intent would be to try to convince current commissioners
that an inspection program of these structures would be cost-effective
in ensuring the safety of the traveling public.
4. Status of Mid-Atlantic
Regional Technician Certification Program (MARTCP) and Transportation
Curriculum Coordination Council (TCCC)
Mr. Woody Hood with MDSHA made
a presentation updating the Certification program. (Note: A copy of the
presentation is attached). Woody passed around a copy of the Pavement
Marking Manual. This manual was the first training program to be promoted
by the FHWA under TCCC and has been distributed nationwide. VDOT’s
Pavement Marking program was used as a guide for development under MARTCP.
Mr. Triandafilou surveyed the
states present at the meeting and all states agreed that SCEF should take
the lead in supporting TCCC development of training for high strength
bolt installers for overhead sign structures. Also discussed was SCEF’s
preference for including field welding inspection training as part of
the current program for concrete and steel bridge construction inspectors.
Inherent in this issue is the need to resolve whether a formal agreement
among the states is necessary to suspend a card-carrying worker from the
entire region, if suspended from only 1 state.
Woody passed around the June
2002 Activity Plan which listed current Work Plan Activities of the TCCC
with descriptions and product delivery dates. (Note: A copy of the Activity
Plan is attached).
(Note: as follow-up to this item, Woody has noted that the TCCC has agreed
to have SCEF take the lead on developing the bolt installer training.
By copy of these minutes, we are soliciting volunteers to participate
in a task group for this effort. It is intended that this group meet after
the next SCEF meeting to discuss the extent of this effort).
6A. Subcommittee Status Report on Large Movement Expansion Joints
The states were asked for their
votes on whether or not to adopt proposed SCEF 109. This is a written
text portion of the specification, with standard detail drawings to follow
at a later date. VDOT voted to accept; PADOT voted not to approve because
of the water absorption value for trough composite properties, and because
of immersion test requirements; MDSHA also voted not to approve because
of the following issues: a) they use a closed-cell foam sealer under their
tooth joints, which is not included in SCEF 109, b) they do not require
joint manufacturers to be certified to AISC major bridge category, and
c) they require trough material to conform to AASHTO M220, with exceptions
that do not match those in section 22.214.171.124. They do have an alternate
material and may consider others in the future.
Mr. Triandafilou asked for
comments from the other states represented at the meeting, and received
none. Based on today’s discussion, he set an action item for the
subcommittee to reconvene before the next SCEF meeting, attempt to resolve
differences in the first balloting, and to craft a consensus document.
The intent would be for a revised ballot to be distributed to the States
with the notice for the next meeting.
Mr. Triandafilou has received
a request for information on how to design a tooth joint on a curved,
skewed alignment where the movement from one unit is much larger than
the movement from the other unit. Anyone with experience with a similar
situation is requested to contact Lou.
6B. Subcommittee Status report on Bearings
Ms. Patti Kiehl with PADOT
made a presentation on the PADOT Pot Bearing Standard. This is a pool
fund study with PADOT as the lead state. PADOT will be requesting other
states to participate in the study in the near future. At present time,
the dimensions on the standard are furnished by PADOT. The Contractor
does not have the option to re-design the bearing but he can submit a
change through the VE process. Patti can furnish copies of the PADOT Pot
Bearing Standard on request. (Note: a copy of the presentation is attached)
With Barrie Atkinson stepping
down as Chairman of this subcommittee, an appeal was made for a new person
to step as chair.
(Note: Since this meeting,
Patti has volunteered to be the new chairperson).
6C. Subcommittee Status Report on Structural Coatings
Mr. Paul Perkins with MDSHA
gave an update on their October subcommittee meeting, which was attended
by about 40 people. Ms. Sandy Compton with Industrial Galvanizers of Virginia
gave a presentation on VDOT’s galvanizing program (approximately
230 bridges completed). Craig Ballinger gave a presentation on Terma-Rust
technology. Joe Bracken and Dave Kuniega gave a talk on PennDOT’s
experiences with metalizing. Paul has been in contact with the Midwest
Paint Group concerning collaborative efforts and possible joint meetings.
Other topics of discussion included use of organic zinc for shop prime
coating; NEPCOAT and NEPOVERCOAT requirements; and availability of the
AASHTO/NSBA document 8.1 on inorganic zinc prime coat in the shop.
Action items for the subcommittee
to discuss at their next meeting include: field cleaning and painting
galvanized fasteners; soluble salts and how critical they are to control,
measure and remove; to overcoat or not overcoat; washing bridges before
painting, and containing the washwater; and states’ coatings practices.
7. Update of AASHTO/NSBA
Steel Bridge Collaboration Activities
Mr. Triandafilou gave a presentation
on Achieving Quality and Value in Steel Bridges. (Copy of the presentation
is attached). Lou requested that each state review and update the AASHTO/NSBA
Document Implementation Survey and return to him. The last update was
October 18, 2002. A list of success stories involving Owner/Fabricator
Resolution of Problems was passed out by Lou. Each State and Fabricator
was also asked to review and submit new success stories from their projects.
8. FHWA/State DOT/Industry Comments on AASHTO/NSBA Collaboration Documents
Mr. Triandafilou asked each
State to go to the web site www.steelbridge.org and review and comment
on the ballot G12.1 - 2002, Guidelines for Design for Constructability
and the ballot G9.1 - 2002, Guide Specification for Steel Bridge
Bearing Design and Detailing.
9. Standard Format for WPS’s and PQR’s - PADOT
Mr. Joe Bracken, PADOT, reviewed
the Welding Procedure Specification form that PADOT is using. Joe covered
a number of enhancements that had been incorporated into the form to ensure
that all pertinent information is included. Mr. Triandafilou received
approval from the States to process this as a SCEF Document. Lou asked
the States to review and provide comments back to Joe within one month.
A recommendation was made that, after SCEF approval, the document would
be sent to the AASHTO/NSBA Steel Bridge Collaboration and AWS for adoption.
10. Curved I-girder Bridge Detailing Practices - A Case Study
Dr. Christopher Earls with
University of Pittsburgh made a presentation on the construction of the
Ford City Veterans Bridge. Erection issues in the form of displacements,
stresses and instabilities were investigated using Finite Element Model
analysis. (A copy of the presentation is attached).
11. Other Issues
PADOT has contracted with Lehigh
University for a Fatigue Fracture Training class. The training is free
and available on March 3&4, 17&18, and April 14&15.
The recent issue of AISI Steel
Bridge News highlighted the ongoing construction of 33 HPS bridges as
part of the Route 3 design/build project in MA.
The next Steel Bridge Forum
will be held in Pittsburgh on June 11th, as part of the International
Bridge Conference. Future forums are tentatively set for Albany in September
and Raleigh in October.
The next full SCEF meeting
will be convened either during the week of Aug. 25th or Sept. 2nd. The
location will be determined later.
