Conflict with CFRP Wrap Installation Due to Fiber Optic Cable
An AT&T fiber optic cable, now managed by Siyeh Communications, runs through a conduit inside the bridge and conflicts with the proposed CFRP wrap installation. The conduit and associated pull boxes must be removed before CFRP work begins and reinstalled afterward. The current plans and specifications do not include special provisions for this work, except that utility removal and reinstallation will be performed by others. Coordinate with Brian DeMarco at Siyeh Communications at least 48 hours before starting work in this area.

The provided table for crack injection has quantities per span but little detail. Should contractors expect crack injection quantities to fall outside of the FRP scope areas on the exterior of the bridge? If so, can you please quantify approximate locations on the outside of the box girder that are outside of the FRP scope? Is the intention of crack injection to supplement the FRP scope or is it intended to be a separate scope entirely?
Answer
Submitted: Monday 10-NOV-2025 01:30 PM
The Two Medicine River Bridge: Main Span Superstructure Inspection Final Report dated December 30, 2022 (See Q&A response #6) provides information on where the cracks are located and the maximum measured width of the cracks. Although the crack injection is required for the CFRP wrap, it is a separate repair. There are likely cracks requiring injection that are located outside the CFRP repair zones.

Special Provision #35 B.2.c states "A single ply of CFRP composite with 0.08'' nominal thickness may be used in place of two plies of CFRP composite with 0.04'' nominal thickness, provided that the composite gross laminate properties are equivalent. Special Provision #35 E.2 states "The square foot measurement presented in the surface area to be treated multiplied by the required number of CFRP layers as required in the Plans. (e.g. A 10 foot by 10-foot surface area, where the plans require three layers of CFRP, is presented in the table as 300 S.F.). If a single ply of CFRP composite with 0.08" is used will double the SF payment be made to account for the thicker material used or will only a single measurement be paid?
Answer
Submitted: Monday 10-NOV-2025 02:08 PM
The quantities shown are based on the number of plies required for the specified CFRP thickness. If the contractor provides thicker plies resulting in fewer layers, payment is still based on the installed quantity, which is measured on a per ply basis.

For Special Provision 31, REMOVE ASPHALT FROM DECK, it states that use of rotomilling to remove plant mix from deck is not permitted. However, under Special Provision 30, the specification allows us to use mechanical milling to reach a shallower depth prior to hydrodemolition. With that in mind, why are prohibiting rotomilling the plant mix? Wouldn't you achieve both outcomes, both removing the asphalt and achieving the shallower depth prior to hydrodemolition, at the same time?

1. Per special provision 3.B(1), all work must be complete on structures 01549 and 01550 prior to any traffic impacts elsewhere on the project. With this being said, will MDT give the contractor a contract time shutdown during the required 28 day concrete curing period prior to applying bridge deck crack seal? This would also apply to structures 01541 and 01568 from once the concrete overlay is poured to the end of the 28 day curing period as traffic will not be able to be put back on the structure until this work is completed as per special provision 3.2(b) and 3.4(d).

Bid this work under the assumption that the rebar remains bonded. If significant debonding is encountered during construction and requires changes to the contractor’s operations, it will be considered extra work and considered for time extension under 108.07.5. The STRUCTURE ANALYSIS bid item is included to pay for the engineering analysis and report.

Can MDT post the design files, mass diagram, dirt runs, and any additional geotechnical information.
Answer
Submitted: Wednesday 12-NOV-2025 09:15 AM
The design files for the requested project are posted here:  DESIGN FILES

The requested files do not represent the staked project, but are only design files.  The Department cannot guarantee the accuracy of the electronic data, particularly as it may be called up by your computer, nor does any data in these files supersede the data in the contract documents.

In addition, the Department will not make any revisions to the electronic files pertaining to the staked project, change ordered work, or changes that are made during construction to fit field conditions.

Linked are PDF Files of the available project alignment and/or structures geotechnical report(s), geotechnical report supplements, and geotechnical laboratory summaries.  There is remaining geotechnical information that is voluminous and very difficult to compile in a concise manner.  Contractors are welcome to come to MDT Headquarters to inspect rock samples taken for the project that are stored here or to look through the complete set of Geotechnical field investigation notes, laboratory testing, analytical, or other data in our project files.  It should be noted that the project may have undergone significant changes during the design process after the original geotechnical report and supplements were issued.  Thus, some of the information contained in these documents may be out of date or not applicable with regard to the advertised project. Some of the changes include, but are not limited to: Project splits (for funding, ROW issues, etc.) alignment and grade changes; and changes due to environmental factors (sensitive areas, etc.).  The documents can be found at the following link: GEOTECH FILES

It appears that you are using 2 single panels to make a right of way break. With Metal Fence Posts there is not a fastening detail for attaching the 2x6 material- Would the state consider stretching the corresponding fence style across the gap as opposed to using treated lumber? Or on recent jobs, the department has used a corner brace offset one side or the other from the right of way monument. If this is acceptable, an adjustment to the single vs double panels would need to be calculated.

Install steel double panels at R/W breaks offsetting the center post one foot to either side so that the property monument will not be disturbed. There are approximately 129 R/W breaks on this project.

On bid item #603012777 RCP 78 IN, would you accept 84 IN RCP in place of the 78IN RCP?
On bid item #603012793 RCP 90 IN, would you accept a 7X7 RCB in place of the RCP?
Answer
Submitted: Thursday 13-NOV-2025 08:12 AM
An 84 IN RCP is an acceptable alternate for the 78 IN RCP at Sta 2396+99. Bid the 90 IN RCP as-is at Sta 2327+87.  Pay quantities will be based off the basic bid items and sizes and will not reflect quantities required for alternate sized culverts.

Will you accept 96" RCP in place of the 90" RCP?
Answer
Submitted: Thursday 20-NOV-2025 01:20 PM
A 96 IN RCP is an acceptable alternate for the 90 IN RCP specified in the contract.  Pay quantities will be based off the basic bid items and sizes and will not reflect quantities required for alternate sized culverts.  The detailed drawings only show FETS for culverts up to 90 IN RCP so the contractor will need to submit drawings/designs for review and approval by MDT for the larger pipe.

Being that the thick topping slab will have entrained air, has that eliminated the need for air entrainment in the bridge girders?
Answer
Submitted: Thursday 20-NOV-2025 10:29 AM
Due to air entrained concrete being specified for the structural concrete overlay, the use of air entraining in the flat slab concrete beams is not required.  Non-air entrained concrete meeting the requirements Concrete – Class Pre is allowed to be used for the Prestressed Girder-Slab beams.

On plan Sheet No. RD-56, a pipe dissipator detail is provided. Note 4 states to install dissipator rings for culvert liners at Stations 139+15, 180+54, and 428+71. However, plan Sheet No. RD-55 shows CIPP liners being installed at Stations 180+54 and 428+71. Are you intending that the 48" CIPP liner be installed first, and that the 44" steel pipe with dissipator rings then be installed through the finished CIPP liner? How do you propose that this work could be completed without damaging the newly installed CIPP liners? Please provide further clarification.
Answer
Submitted: Friday 21-NOV-2025 10:31 AM
The contractor has the option to install steel pipe with internal dissipation rings or to use a CIPP method with appropriate internal dissipation rings that must be installed accordingly to CIPP manufacturer recommendations and standards. Only one rehabilitation method may be used at each crossing location, a CIPP liner should not be installed in addition to a steel liner.

Can you provide clarification on the Cured-In-Place Pipe (CIPP) bid quantities? In the file "9487001ADV_PLANS”, Sheet No. RD-55 on PDF pg. 55, CIPP lining is described at Stations 180+54 and 428+71 (total 534 LF of 48"). However, in the file "“9487001ADV_PROPOSAL”, the bid Schedule of Items does not include any CIPP bid items.
Furthermore, in the file "“9487001ADV_PROPOSAL”, Cured-In-Place Pipe (CIPP) Drainage Structures, Article 42.E.2.c (PDF pg. 39) states to remove the existing baffle before installing the CIPP liner in the 108" pipe at Station 267+82, which contradicts Sheet No. RD-55 which calls out a new steel pipe being inserted not CIPP lining. In the next paragraph, Article 42.E.2.d (PDF pg. 39) it states to install internal energy dissipation rings at Stations 139+15, 180+54 and 428+71 as part of CIPP lining. Again, this contradicts Sheet No. RD-55 for the pipe at Station 139+15 which calls out a new steel pipe being inserted.
If we go by the culvert lining detail on Sheet No. RD-55, we’re only CIPP lining at Stations 180+54 and 428+71. If we go by the CIPP lining specification in “9487001ADV_PROPOSAL”, PDF pg. 39, we should be CIPP lining at Stations 139+15, 180+54, 267+82 and 428+71. If we go by the bid schedule, there’s no CIPP lining at all.

In the bid Schedule of Items, Prop Line No. 0420, Item Number 603016054, Steel Casing 48", a bid quantity of 178 LF is provided. In the bid document "9487001ADV_PROPOSAL", in Article 41.A (PDF pg. 29), a table is provided that gives a bid quantity of 178 LF of 48" at Station 139+15, which seems to correspond to the bid item referenced above. However, on plan Sheet No. RD-55, the culvert lining detail gives a quantity of 166 LF of 48" at Station 139+15. Please clarify.

We previously asked a question about internal dissipation rings and CIPP. The response provided was that the "appropriate internal dissipation rings must be installed according to CIPP manufacturer recommendations and standards". When a steel pipe liner is used, the detail on plan Sheet No. RD-55 shows the dissipation rings being welded to the steel pipe. By contrast, no detail is provided how to install and secure the internal dissipation rings when CIPP is used, since dissipation rings cannot be welded to the CIPP liner. There are also no CIPP manufacturer recommendations and standards for this work. Please provide additional details on how this work is supposed to be completed so all contractors can provide pricing on equal grounds.
