Plan page 26 under the Concrete Barrier Rail summary, there is a note that reads "High visibility linear delineation will be adhered along the top of all concrete barrier rail." Please clarify if this is referencing the standard top mount reflector shown in the 605 Standard Drawings that is spaced at 30ft intervals or if the Department is requesting the product known as Lineal Barrier Delineation that mounts to the side of the barriers and usually is covered by a separate bid item. If it is the standard top mount reflectors, will they remain at 30ft spacing or is there to be a reflector at 10ft to meet the requirement of "all concrete barrier"? If the Department is requesting Linear Barrier Delineation, please clarify how many panels per barrier, one or both sides, and consider adding a bid item for the requested work. Additionally, if it is Lineal Barrier Delineation that the Department is asking for, does the contractor still mount the top mount reflectors at 30ft spacing as shown in the 605 Standard Drawings.
Answer
Submitted: Tuesday 19-AUG-2025 02:12 PM
Linear Barrier Delineation is required, two panels per barrier on the inside of curves.  Mount linear delineation for barrier at the normal barrier height on tall concreate barrier rail. 

Bid Item 619 011 205  DELINEATION-LINEAR-BARRIER-YELLOW, quantity of 2780 EA, will be added by amendment.

An amendment will be issued, updated bid files will be posted. UPDATED PLAN SHEET S1

Special provision 47 addresses the use of the existing crossover at the south end of the project including the requirement to provide & install NCHRP 350 cable rail. There is existing NCHRP 350 cable rail at that crossover that will need to be removed. Will the department consider removing only the cable rail items that interfer with traffic and resetting as opposed to completely removing and supplying/installing new cable rail? Is the cable rail to be in place between the 2026 and 2027 season or once all work on the project is complete?
Answer
Submitted: Monday 18-AUG-2025 07:18 AM
Yes, remove all the existing cable rail interfering with traffic or the work and reset to close the crossover after the work is complete  
Close the crossover with 36” hinged flexible guideposts spaced every 8’ on center when not in use in-between season. Include the cost of this work in the 618030300 CROSSOVER-MAINTAIN, CLOSE bid item.

1. Is MDT aware of any upcoming superload projects permitted to move through the project that would impact the Wide Load Marshalling bid item?
2. SP 53 & SP 54 reference a 12' width restriction only. On past projects in the area, length was a major limiting factor to escort abilities due to restricted turning movements, overhang, travel speed, etc.
A) Will a length restriction be imposed during construction?
B) If no length restriction is imposed, will MDT allow full closures of I-15 to accommodate superload escorts? On the previous project, moving a single round of superloads required up to two hours. If escorting takes longer than the allotted two hours, how will the contractor be compensated? What requirements will apply if full closures are permitted?
Answer
Submitted: Monday 25-AUG-2025 10:45 AM
1. MDT is not aware of any super load projects currently.
2. Length restriction will be 95’ excluding double and triple combinations.

Special provision 46 provides the requirements for work performed at the crossover on the north end of the job and applies to bid item Crossover-Median Barrier Rail. Plan page 31 provides additional details for this crossover. The bid item Ramp Crossover does not have a special provision or plan page specific to the work to be included but would be the same scope of work as covered in sprecial provision 46. Is the work covered under the bid item Ramp Crossover to be per special provision 46 and details specific to barrier removal and temporary impact attenuators on plan page 31?
Answer
Submitted: Monday 25-AUG-2025 11:20 AM

We continue to make every effort to meet the 10.1% SBE participation goal; however, despite significant outreach by phone and email, including multiple attempts to engage many of the firms listed in MDT’s directory, we have been unable to secure the necessary participation. Based on the size and scale of this project, we do not believe the current goal is attainable. We respectfully request that the Department consider reducing the SBE goal to a significantly more realistic level.

MDT is committed to setting project specific goals on projects over 10 million.  Project specific goals are weighted based on availability of DBE/SBEs who perform the specific work types the project requires.  Due to these factors, the Sieben Interchange – North goal is set at 10.1%.  If the SBE goal cannot be met, the bidder must provide documentation that they made a good faith effort to meet the goal by 5:00 pm on the day of the bid opening to mdtdbeprogram@mt.gov. The Bidder must follow the DBE Good Faith Efforts Procedure outlined in the Department’s DBE Program Plan.

1. We need to assume a deck condition after Bridge Deck Milling for Engineering Analysis. Previous Q/A instructed the contractor to assume no debonding of the top mat of rebar. The Department also stated that changes in the contractor’s operations resulting from reduced deck capacity would be considered extra work. Will this project follow the same guidelines?
2. Can the contractor use the live lane for hydra-platform access to Class B areas? We are asking for 3-4 hr. road closure in the middle of the night.

The three-sided box which we supply includes a haunch with multiple angles, which would be located under the infill.
Would this difference be acceptable? Do you need to see a cross section?
