Reading through the specifications for the Cold Recycled Plant Mix, we noticed that a closed loop circuit crusher is required to meet the 100% gradation under the 1.25" sieve. Would the state allow a Single Unit, Wirtgen 380 CRi recycler to perform the milling/crushing/mixing to meet the specification? Numerous states that do CIR each year, such as SD, ND, MN, IA, WI, all allow single unit trains to perform this work. The specification that is currently written will only allow one contractor to perform the CIR. Montana DOT would be pleased with the Wirtgen 380 CRi and the overall final product. Please feel free to contact Dave Johnson, PE a senior Regional Engineer at the Asphalt Institute for questions regarding the use of a Single Unit Train.

This road is out of section and the cold-in-place will not noticeably change that. Then the overlay is only 0.1' thick which does not allow for any shaping of the roadway. Would MDT add a leveling course to the entire project (1,000 ton/mile) in order to improve the ride and strengthen the section?
Answer

1.) The last four projects in the Glendive District that have specified 3/8" Plant Mix have failed the Hamburg Rut Test. The specified depth of the 3/8" Plant Mix on this project is 0.10'. It is more of a wearing course than a structural component of the surfacing section. Would MDT be willing to waive the requirement of having a passing Hamburg Rut Test in order to mitigate that risk?
2.) The last overlay that we placed over a cold recycled section required great effort in order to get compaction. It ended up breaking up the cold recycled section under it in order to achieve density. This resulted in a rough end product. Would MDT be willing to go with a compaction standard established by test strip in order to avoid breaking up the section and potentially ending up with a rough end product?
Answer

Would the Department consider making their pit off of Timber Creek Rd near the Haugan scale site available for aggregate production and hot plant site and production.
Answer:

After careful consideration, the pit near Haugan scale site will not be available for aggregate production and a hot plant.  MDT maintenance uses the site for salt sand production, and it is also occupied by MCS for their shooting range.  Material is also limited in the pit.

Sheet 11 shows a detail with the guardrail post installed in the slope of the asphalt. Does this installation require the asphalt removal, gravel backfill and fog seal? If so, does this apply to all of the Reset Guardrail or can MDT give the contractor an approximate length of guardrail that will require this type of installation?
Answer
Submitted: Wednesday 24-SEP-2025 08:35 AM
Guardrail posts may be placed directly through this thin layer of asphalt with no material needing to be removed behind the posts.  Please refer to the third note on plan sheet 11.  The only location anticipating any asphalt removal, millings backfill, and fog seal is the embankment aprons, and the plans have details and lengths of those aprons.

The project is specifying remove and reset of the guardrail at the idnetified areas. Would the MDOT consider revising to new installation for the following reasons: 1) Some of the existing wbeam is damaged and would need to be replaced, 2) The means and methods of installing wood posts would likely have a negative impact on the steep eroded shoulders causing more damage, 3) Hardware likely not reusable from the affects of magchloride, 4) May need to cut rail to get apart due to magchloride on hardware, 5) The new construction detail and steep shoulders will not leave any backfill gravel for wood post installation resulting in additional costs to import and place.
If the MDOT continues forward with resetting of guardrail, what are the requirements and expectations of cleaning the guardrail as mentioned in special provision 23? Notes on plan page 11 apply to guardrail posts installed through asphalt and state that installations that are too thick will require cutting out the asphalt when directed by the PM. Is it paid extra when directed by the MDT? Do the notes on sheet 11 only apply to guardrails that are not in aprons vs special provision 23.C.4 where it directs the contractor to peform cut outs in asphalt aprons at guardrail posts?

Special Provision 52, Traffic Control and Sequence of Operations, states that all work on Shields Ave must be completed before any other area of the project is worked on. What is the reason for this? The scope of work on Shields Avenue is minimal, in the overall scope of the project, and is largely temperature dependent. So doing this work in April, at the start of the construction season, when the weather in Butte is not as favorable, will cause a longer closure due to weather limitations and have a greater impact on the traveling public. Please consider allowing work on other aspects of the project prior to, or concurrently, with the work on Shields Ave, with the understanding that work at Shields Ave will be completed as swiftly as possible once the closure is in place.

The notes applicable to High Tension Cable Rail on sheet 7 and information shown on sheet 11 do not make sense. The notes indicate that only the anchor block is considered for the price of the High-Tension Cable Rail Terminal Section and that Anchor Posts are paid under the High-Tension Cable Rail. Crossover #2 would have equal removal and installation which works out. Crossover #1 shows the installation of the new run to overlap the existing which should result in increased quantity of new vs removal in addition to the Terminal Posts necessary for the exiting runs.

Sprecial provision 24 references both bridge and road guardrail but there is no work on this contract that would affect the guardrail systems on either of the two bridges. Does this provision apply to the guardrails off the bridge? The provision also mentions salvage to the Bridger Maint Yard but there is no other information in the contract with specific requirements for that salvage. The white painted guardrail is identified on site and not of concern per the provision. Is there grey painted guardrail off the bridge (as referenced to contain lead) and is it different from the galvanized guardrail which is also grey? Part C. 2) apears to apply only to "bridge guardrail". Is there guardrail off the bridges that contains lead that must be addressed?
Answer

Both bridge and road guardrail information are provided as the special provision applies to both guardrail types. Work only includes road guardrail which is both white and gray. Road guardrail including the bridge approach sections are either grey or connect to the grey lead painted guardrail. Grey painted guardrail is different from galvanized guardrail. Properly dispose of all grey lead painted guardrail per the special provision.

I have questions regarding Special provisions 24.C.4 and 24.C.4.a. Grooving. Furnish a self-propelled grooving machine equipped with stacked diamond cutting blades to perform the work. Furnish a machine capable of providing uniform depth and alignment. Do not use grinder type heads. Are PCD heads approved?
a) Provide a groove depth of 120 mils ± 10mils. This looks like a spec for tape application. I think it is in the best interest of the department to require a groove depth of 30 to 40 mils. Anything deeper than that collects water and residue which creates a loss of reflectivity.
Answer
Submitted: Friday 03-OCT-2025 02:15 PM
Submit the grinding system to the Project Manager for approval, the intent is to leave a uniform stripe groove for pavement marking application meeting the requirements of the special provision.  Alternative grinding methods will be required to demonstrate this ability of uniform groove, a 2000-foot test section will be required to prove the performance of the grinding equipment.  Unacceptable groove appearance includes but is not limited to undulations in the groove in the direction of travel, perpendicular to the direction of travel, as well as grooves that detrimentally affect the final pavement marking application.  Do not grind ahead of the test section until approval is granted from the Project Manager. 

The groove depth of 120 mills will not be changed.

In regard to the 8 foot tall wildlife fencing. Would the M.D.O.T. Consider a design change to a metal panel and steel line post-game fence system? The reasons are 1. Steel save the M.D.O.T. Costs long term in maintenance and replacement. Wood posts decay overtime and the fence will need to be replaced. 2. Steel fences will not burn in a fire. 3. The area where this fence is being installed in a river bottom corridor which has very rocky gravelly soil. Metal fence posts drive and remain stable in rocky soils more efficiently than would and are less apt to be compromised in the installation. Question 2. Has the department factored in the line of fence footage twice through the single panels on the 8-foot wildlife fence? The wire is stretch twice through the panels going both directions and is paid twice. In the past the department has not had this footage in the line of fence quantities and has had cost overruns of 15’x the # of panels on the projects. Please recalculate footage. This would apply to both wood and steel fence systems.
Answer
Submitted: Friday 26-SEP-2025 08:55 AM
1. Wood posts will be required for this project.
2. The fencing will be paid once through the single panel. New fence is measured by the foot. The measurements are made on the fence line along the top wire or rail or along a line parallel thereto, from end post to end post including wing fences to structures.

Regarding bid items 607100149, 607100360 and 607100380. The M.D.O.T. Has designated wood line posts and brace panel systems. It is our professional opinion the there is greater benefits to switch from wood posts to steel line posts and steel panels (M.D.O.T. Drawing 607-5). We ask the M.D.O.T. To consider a change. Here are our reasons. 1. The project site is in a dry fire prone area. We have been replacing fire-burned wood fence around the state of Montana with steel fences and panels and believe it would be wise to do so on this project. 2. Steel post do not rot and decay. Saving maintenance and replacement costs. Steel post tend to pound in, through and around the rocks that will be encountered on this job. While wood posts are more apt to explode while pounding. They are also not as able to get to depth in rock. 3. Steel fence is easier for maintenance to maintain and the Department has called out the 607-5 detail on the majority of jobs in recent years. Will the state consider a change to these bid items?

In analyzing the brace panel quantities for 607100360 and 607100380 as well as looking at where they are called out on the plans, would the M.D.O.T. Recalculate the quantities as they appear to be inaccurate. Per drawing 607-10, Single panels are used for cross fences as well as at starting points and ending points. Double panels are installed at max spacing of 660 feet on woven wire fences as well as at angle changes and at the top and bottom of hills. In all recent projects double panels far exceed single panels in total quantity.
Answer
Submitted: Monday 29-SEP-2025 10:00 AM
The original plans were based on as-built data and existing conditions. Modifications to panel layout may be required based on the existing terrain. Final layout to be approved by the project manager.

The following revised plan sheets 4 and 10-18 have been revised reflecting modifications to the single and double panels and the associated quantity revisions. PLAN SHEETS 4, 10-18

The quantity for item FARM FENCE-PANEL/DOUBLE FW 607 100 380 has been updated to 224 EACH.

Would the state consider reevaluating the gradation requirements on the foundation material for the Wildlife Jumpouts? These requirements are not achievable. The last two jobs completed in the Missoula and Butte districts have requested the same gradation, however, 100% passsing the 1/2 inch and 5% passing the #200 has not been achievable. The department, on both projects prior, did accept a less stringent, yet very clean material as a substitute. Could the gradation requirements be changed, or would an approved substitute be accepted?

On the Right side of the job at station number 185 + 09.60 there is a concrete canal right next to the fence-line. Currently there are gaps in the existing fence where the canal has a concrete wall that is currently as tall as a jump out. Then there is a section of fence installed rock backfill behind the concrete wall where it is shorter. Would attaching a chainlink fence to the top of this concrete wall to achieve the height requirement for this short stretch be an acceptable alternative to installing wildlife fence in loose rock behind the concrete wall?
Answer

In the special provisions variable message boards have been called out. On past projects, traffic control has been handled with two road work ahead signs facing traffic at both ends of the job. All fencing and jump out activity is generally handled with a shoulder closure and reduced speed signage as well as an occasional lane closure while fencing on underpasses and frontage roads. As currently proposed this project will not require road closures or detours as the majority of the work is in the right of way. Would the M.D.O.T. Consider not using variable message boards to save project costs?
Secondly. If the M.D.O.T. Ads cattle guards to the project, variable message boards would be needed for a short time while the cattle guards are being installed on the on ramp and off ramp as there would be a brief road closures.

In response to the answer for question 6, the soil condition behind the concrete ditch is currently large boulders loosely stacked as backfill. The ditch has high sides and is 4-5' wide. Does the state have a plan for how to install those posts so that they remain in place. Keep in mind it is virtually impossible to get any piece of equipment to this location, and it will need to be installed completely by hand. It could benefit the state significantly to have a clear plan for this location; this would limit a change order in field if a clear plan was put in place. One solution would be to attach the fence to the top of the concrete ditch bank.

Are spin bottom buckets allowed for shaft cleanout if wet or loose soils are present?
Answer

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.

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.
