ACEC/Maine DOT Bridge Design Subcommittee - 6/11/13

ACEC/Maine DOT Bridge Design Subcommittee

MEETING MINUTES

11 June 2013 ________________________________________________________________________ Attendees: Location: MaineDOT Room 317A/B Wayne Frankhauser MaineDOT Laura Krusinski MaineDOT Leanne Timberlake MaineDOT Time: 1:00PM – 2:15PM Marie Malloy MaineDOT Chris Snow GZA Jason Gallant CMA Engineers Craig Weaver Kleinfelder Steve Hodgdon VHB Steve Percassi Erdman Anthony Notes Taken By: Steve Hodgdon ________________________________________________________________________ This is the second quarter ACEC/MaineDOT Bridge Design Subcommittee meeting.

Information from MaineDOT

o The 2-year (2014/2015) work plan is now posted on line. Many of the

projects will be kicked-off this summer and fall.

o The 2013 bridge load ratings have been assigned. Leanne Timberlake is assembling another batch of ratings for assignment in 2014.

o The Department continues to see competitive construction bids. Nearly all

projects are coming in at or below the PS&E estimate. o The Department is short-handed with contract specialists and looking to hire

another. She also reiterated that consultant invoices need to be complete and include all the necessary backup including timecards, A-1 sheets (when there is a pay rate change or new person), and documentation of all receipts/expenses. Only approved wage rates may be billed.

o The MaineDOT Chief Engineer is retiring the end of June. Finding a

replacement is in progress. o The scheduled date for the new Standard Specifications Book is January 2014.

ACEC/MaineDOT Bridge Design Subcommittee of 3 Meeting Minutes 11 June 2013

o The Chief Engineer is working on the review of the Chapter 5 rewrite of the Bridge Design Guide (BDG). The Department hopes it will become part of the BDG once all comments are addressed and final revisions incorporated.

o Copies of the last three (3) Designer Meeting minutes (5/1, 5/15, and 5/29)

were distributed by the Department (see attached). Two of the meetings consisted of presentations. One by DS Brown on a spray applied deck membrane system (Deckguard) and the other by Lochner on their Route 1 Gateway bridges in New Brunswick, Canada.

The May 15 meeting included an assessment of elastomeric bearing

design inconsistencies in the Bridge Design Guide, Specifications, and AASHTO. The Department will work on drafting revisions to the BDG and Specifications for internal review.

The May 15 meeting also included “lessons learned” regarding a box culvert project on Mount Desert Island and splice locations for steel finger joint assemblies.

o MaineDOT is in final design of a NEXT beam bridge in Kittery that includes

carbon prestressing strands. The project includes techniques from the latest ABC Toolkit manual that was recently published and funds from a SHRP2 Grant. It is anticipated to be advertised in January 2014.

Strip Seal or Gland Seal Expansion Joints

o MaineDOT’s current gland seal detail is not performing well and the Department is considering revisions for improved durability. The consultant members presented the Department with an overview of expansion joint details and practices used in neighboring states including: New York, Pennsylvania, Connecticut, Massachusetts, Vermont, and New Hampshire.

o Connecticut – Craig Weaver provided a packet (see attached) to the

committee with a summary of the Connecticut DOT Expansion Joint Systems including a 2/25/2011 memorandum that includes revisions to their strip seal expansion joint for new construction and rehabilitation projects.

o New York and Pennsylvania – Steve Percassi provided standard detail sheets used by each of these states (see attached). Also, Steve noted that NYSDOT prefers/uses the modular joint compared to the finger-type joint.

o Massachusetts and Vermont – Steve Hodgdon provided information and details by each of these states (see attached). VTrans does not use a gland-seal as a standard. They have been using their “Vermont Joint” for many years. Massachusetts does use a strip seal.

ACEC/MaineDOT Bridge Design Subcommittee of 3 Meeting Minutes 11 June 2013

o New Hampshire – Jason provided NHDOT details and guidelines from their Bridge Design Manual (see attached). The New Hampshire joint details are robust in comparison to the other state details presented.

Subcommittee Rotation

o Steve Percassi has his last meeting at the Q3 meeting this year. Keith Donnington is taking his place starting at the Q4 meeting this year.

Future Meeting Topics

o Steve Percassi will prepare and summarize their recent experience rehabilitating and strengthening a concrete through girder bridge using FRP wrap.

o Laura Krusinski noted that some research projects are expected to be complete at the University of Maine. The projects included a compilation of pile load test data and potential refinements in the Nordlund method for capacity in/on rock. Once the projects are finalized, the information can be discussed at a future meeting.

Next Meeting Date

o Tentatively August 20, 2013 at 1:00 PM, MaineDOT Conference Room 317A/B. Wayne will send a confirmation email.

Attachments: Designer Meeting Minutes from May 2013 Expansion Joint Information from NY, PA, CT, MA, VT, and NH I have attempted to summarize discussions held during this meeting as accurately as possible. If there are any items discussed herein that are misrepresented in any way, please contact me within ten working days. In the absence of any corrections or clarifications, it will be understood that these minutes accurately summarize the discussions at the meeting. Respectfully Submitted, Steven Hodgdon

DETAILS PROVIDED ON THESE SHEETS ARE

DEVELOPED FOR CONVENTIONAL MONOLITHIC

VERIFY THE SUITABILITY OF THESE DETAILS

FOR OTHER DECK SYSTEMS AND MODIFY

THEM AS NECESSARY.

FOR LOCATION OF SECTION D-D, SEE BD-JM1E

AND BD-JM2E.

BRIDGES WITH A SKEW GREATER THAN 30 n

MUST USE COVER PLATES.

FOR COVER PLATE DETAILS, SEE BD-JM11E

NOTES:

IT IS DESIRABLE TO HAVE THE MODULAR JOINT WITH ITS

SEAL ASSEMBLED IN THE SHOP AND DELIVERED TO THE JOB

SITE ALL SET FOR INSTALLATION IN ITS PREFORMED RECESS

IN THE STRUCTURAL SLAB. IN CASES WHERE THE JOINT

CANNOT BE ASSEMBLED IN THE SHOP, DUE TO ITS EXCESSIVE

LENGTH CAUSING SHIPPING PROBLEMS, THE JOINT SHALL HAVE

THE SEAL IN PLACE BEFORE THE STRUCTURE IS OPENED TO

TRAFFIC, INCLUDING CONSTRUCTION TRAFFIC, AND BEFORE

DISCONTINUING OPERATION WHEN WORK IS SUSPENDED DURING

THE WINTER.

MODULAR JOINT SHOWN IS FOR ILLUSTRATIVE PURPOSES ONLY.

ACTUAL JOINT SUPPLIED MAY VARY SIGNIFICANTLY FROM THE

ONE SHOWN HERE. IT IS THE CONTRACTOR’S RESPONSIBILITY TO

ADJUST ALL REQUIRED DIMENSIONS IN THE FIELD, BASED ON FIELD

VERIFIED DIMENSIONS, TO ACCOMMODATE THE ACTUAL MODULAR

JOINT SUPPLIED.

STRIP SEAL OR BOX SEAL MAY BE USED AT THE CONTRACTOR’S

OPTION.

THE ASSUMED DIMENSIONS OF THE BLOCKOUT (DEPTH AND WIDTH)

ARE PLACED ON THE PLANS. IF THE JOINT SYSTEM SUPPLIED BY THE

FABRICATOR/CONTRACTOR REQUIRES A CHANGE TO THE BLOCKOUT

SIZE OR SUPPORT SYSTEM (I.E. END DIAPHRAGM, ETC.) DETAILED

IN THE PLANS, THAT CHANGE TO THE BLOCKOUT OR SUPPORT SYSTEM

SHALL BE THE CONTRACTOR’S RESPONSIBILITY. NO ADDITIONAL

PAYMENT WILL BE MADE FOR THE CHANGES TO THE BLOCKOUT OR

SUPPORT SYSTEM AS A RESULT OF THE SUPPLIED JOINT SYSTEM.
