Attached 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 2511 Holman Avenue, Billings, MT 59102 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 Thus, some of the information contained in these documents may be out of date or not applicable with regard to the advertised project.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: GEOTECHNICAL REPORTS
One shear test was performed on Boring ST-7.

Is there a spec for the permanent casing embedment into the bedrock?
Who makes the determination of when to advance the bottom of casing beyond the design elevations?
Is casing installation method at the contractors discretion?
Are spin bottom buckets allowed for shaft cleanout if wet or loose soils are present?
Answer
Submitted: Monday 06-OCT-2025 02:35 PM
1. Not specifically.  The estimated tip elevations are shown on the drawings but may be subject to variation based on the conditions encountered.  Install the permanent casing to facilitate stable excavation, cleaning, inspection, and quality concrete placement.
2. The Contractor is ultimately responsible for satisfying the requirements set forth in the contract documents.  The decision of where to terminate the permanent casing is anticipated to be a collaborative effort between the Contractor, MDT’s Project Manager, and a Geotechnical engineer.  Address this important item in the required installation plan submitted for approval, as well as discussed in the shaft pre-construction meeting.
3. Yes, subject to the requirements of the contract documents and as approved in the required installation plan.
4. Yes, spin bottom buckets may be used to help with the cleanout, although per Special Provision #57, an airlift or other approved equal is required for the final cleanout.

Requiring traffic back on the bridge October 2026 means that there will be no demolition taking place in 2026 and just some deep foundation and access work. That leaves 150 working days to remove and replace a tall 800 foot bridge with difficult access and environmental concerns. That is not sufficient time. Just cure time alone will use almost 30 percent of these days. Please consider a more permanent detour that allows work through the 26-27 winter so demolition can start in 2026.

SP 42 says "Remove the entire existing structure including but not limited to the deck slabs, beams, bridge rails, curbs, end bents, intermediate piers, foundations, and all incidental items." Drawing B4 shows the in-water piers being removed 3' below grade. Does the 3' below grade removal apply to the other piers, as well as the abutments or are they to be removed in their entirety? If the latter, then it appears shoring would be needed on the west side as well as the east, even though B4 only shows it on the east. Please advise.

Per Standard Spec 558.03.7 (4) corrosion protection is required for all permanent casing. One of the requirements (c.) for painting the casing gives some limits to apply paint when in water channel or when the steel is exposed. There are no requirements listed for galvanizing. On this project the permanent casing is not in the water channel or appear to be exposed above finished grade. Can you confirm if there is a requirement for corrosion protection on the permanent casing, and what is it?
Answer
Submitted: Thursday 16-OCT-2025 12:52 PM
Refer to 558.03.7.c which states the portion of the casings that would require paint.  Corrosion protection is not required if the permanent casing is not in the water channel or exposed above ground elevation.  Any permanent casing installed that is exposed must be painted in accordance with 558.03.7.4.

Our team has invested a considerable amount of effort in developing viable access plans for this challenging project site. These plans still require further subcontractor vetting and engineering analysis to validate means and methods and confirm cost accuracy. Maintaining the current bid date of October 23rd would limit our ability to adequately price our self-performed work and hinder our trade partners from submitting competitive proposals of their own in advance of our bid submission.

We request the bid be postponed to provide additional time for the necessary access coordination with adjacent property owners. We have also heard from our engineers that the engineering analysis of the demolition and de-erection of the existing structure will take longer than anticipated, and additional bid time will allow us to reduce the risk contingency in our estimate. Additionally, the extensive design and analysis of the proposed temporary access and erection planning and stability requires much more engineering effort than a typical project. The state will benefit from reduced construction pricing by postponing the bid.

Would the Department consider changing this project to use crossovers so that workers have less exposure to the traveling public. It has been very evident on all of the active projects the last two seasons that the occurence of crashes in and around the Bozeman area are more frequent than other projects around Montana. The benefit that night construction offers to the public for congestion purposes is more than offset by the increased risk presented to workers at night. Traffic control devices, lights, and reflective clothing are not sufficient to protect workers from growing concerns of exposure to the traveling public in that corridor. Regardless of whether work is performed at day or night, there is a unusually higher risk to highway workers on this project.
Answer
Submitted Wednesday 15-OCT-2025 3:06 PM 
Due to the impact to interchange operations and larger global local road impacts, crossovers will not be allowed.

The details in the project include milling and paving full width of the roadway. In areas that include guardrail work, guardrail would need to be removed prior to milling and then replaced following paving operations. Special provision 5 states that all areas where guardrail is removed, it must be installed the same shift prior to opening to traffic and lane closures are not allowed to remain in place. Realistically in areas where guardrails exist, the work area will be limited to approx 100ft per shift to allow time to set up traffic control, remove guardrail, mill, place tack oil, place pavement, allow to cool, install guardrail, and remove traffic control. Accordingly, this contract will need a minimum of 69 days alone for the work that is performed in guardrail areas. The Department will need to add at least 75 working days to the contract or clarify that guardrail work is not affected in any way by other contract work and can be performed independent of all other operations.

In accordance with the special provision - Remove guardrail within 200 feet of bridge ends to pave full width. Remove guardrail, complete milling and paving, and replace all the removed guardrail at the end of each shift, prior to opening to traffic. Milling and paving through other guardrail sections can be completed with the rail in place.

Special provision 5 includes language specific to the bridge end work at RP 303.6. As stated in a previous Q&A, the amount of listed work of 200 lineal feet can not be performed in one shift. Removing and installing bridge approach guardrail requires more time than standard guardrail and further requires forming and pouring a concrete curb taper with form stripping occuring at a later time. Additional resources have no ability to increase production as only so much equipment and personnel can fit into a 200ft area and none of the listed work can be ongoing simultaneously. The request is unrealistic and can not be performed as stated which will lead to the contractor failing to comply with the requirements in special provision 6.

Special provision 30, Temporary Barrier Rail, describes payment for Reset Temporary Barrier to include any barrier previously used on the project. It has been understood for many years that Reset Temporary Barrier was the pay method used when temporary barrier was shifted in the work zone by use of lifts or cranes whereas temporary barrier that must be moved a greater distance than a shift was paid under Temporary Barrier. The distinction was accurate as the price for temporary barrier is significantly higher than reset temporary barrier as it includes loading, trucking, and unloading. The proposed method of payment in SP 30 will now intermix two distinctly different types of work into the same bid item, Reset Temporary Barrier. This will further cause problems if there are change orders or revisions to the project that include Reset Temporary Barrier. The temporray concrete barrier summary on page 9 indicates what quantities will be paid and how they will be paid. If one bridge is worked on first and the second bridge following completion of the first bridge, will the temporary barrier be paid as a reset to haul between the eastbound and westbound structure or does the payment method shown on sheet 9 apply?
Answer

Bid resets in accordance with Special Provision 30. It is an unknown if the successful bidder will work on the structures simultaneously, temporary barrier rail and reset temporary barrier rail quantities on page 9 accurately reflect the quantity in the event that the successful bidder chooses to do so.

The design files for the requested project are posted here: DESIGN FILES DESIGN FILES-ALL
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.

Attached 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.).

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?
