Item #104030070 Miscellaneous Items-Removal LS relates to Special Provisions #46 Timber Decking for Private Landowners. This calls for clear and deck all timber specified from designated areas. Could you provided clarification if the work for this includes felling trees or if it only includes decking timber that has previously been felled? There is currently felled and de-limbed timber that can be seen adjacent to the job in many of the specified parcels. This felled timber looks to have been part of tree clearing that took place beneath the power lines. Does this item account for decking the timber felled for the power line in addition to timber that hasn’t been felled yet? If this item is to account for the cost of felling timber on the specified parcels, what about the felling of timber on parcels that are not specifically designated? Lastly, it states efforts are to be made to preserve live timber. Will MDT mark the trees that MDT wants to be removed? Has there been an approximate tree count that MDT expects to be taken for removal?
Answer
Submitted: Friday 18-SEP-2026 09:42AM
Work required in special provision #46 Timber Decking For Private Landowners only includes decking of trees for the specific parcels as outlined in special #46. All remaining tree clearing that wasn’t already performed by utility companies is included in the cost of clearing & grubbing, paid via LS. Some trees were already felled and de-limbed for utility relocations.  If these felled and de-limbed trees are within the limits of the decked trees as outlined in special #46, then perform the decking for these trees.  Decking does include previously felled trees and trees that still need to be felled.
Only trees within clear zone and within construction limits need to be cleared.  If the trees are located outside construction limits and outside clear zone, then the trees can be preserved.  Refer to the do not disturb note on the notes sheet of the plans for additional trees that are not to be disturbed.  MDT will stake construction limits, but the trees that are required to be removed will not be staked.  There is not an estimated number of trees for removal.

Follow up question to the SP#46 Timber Decking. When will MDT stake construction limits? - prior to bid or after award? What method or station distance do you intend to stake construction limits?
Answer
Submitted: Wednesday 23-SEP-2026 04:10 PM
MDT plans to begin slope staking the week of September 28^th.  It is not guaranteed that all slope staking will be completed prior to bid.  Slope stakes will generally be set at 100’ intervals on tangents and 50' intervals through curves. Clear and Grub limits will extend 10’ beyond the catch point, or to R/W line, whichever occurs first.

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:

Reference: Special Provision #35 (Clean Water Act Section 404 Permit and Section 401 Certification), Section C.1.c Question 1: Does the Biological Resources Report, Aquatic Resources Form, ESA/Section 7 documentation, and Section 106 cultural resources documentation prepared during design already cover the temporary construction footprint (work bridges, cofferdams, diversions) at the affected crossings, or is the Contractor required to commission new studies to support the NWP 33 application? Reference: Special Provision #35, Section C.1.d-e Question 2: If USACE's review of a complete RRS submittal extends beyond the standard 45-calendar-day period through no fault of the Contractor, is additional contract time granted, or is this schedule risk borne entirely by the Contractor?
Answer
Submitted: Tuesday 06-OCT-2026 08:57am
Question 1:
The Department’s Biological Resources Report, Aquatic Resources Form, ESA/Section 7 documentation, and Section 106 cultural resources documentation are available for the Contractor’s review and use in determining whether a pre-construction notification is required. These documents address the areas and effects evaluated for the project. Temporary facilities or associated effects not addressed by the existing documentation are the Contractor’s responsibility and may require additional environmental review, documentation, or consultation.
Question 2:
As stated in the 404 special provision, preconstruction notification is not automatically required for NWP 33. The Contractor must determine whether a PCN is required based on its proposed temporary facilities and the applicable NWP general and regional conditions. If a PCN is required, allow a minimum of 45 calendar days following USACE’s receipt of a complete PCN for review. Requests for extensions of contract time will be evaluated in accordance with Standard Specification 108.07. The Department is not responsible for delays caused by incomplete or inaccurate Contractor submittals.

Special Provisions #58 Abandon Well. This calls for abandoning three wells that will be in conflict with roadway embankment. Could MDT identify the well IDs for these wells so contractors can better plan for their abandonment? The GIS map lists the following wells near these locations: Well ID # 706716 near STA 239+25, I cannot locate this well in the field. It claims to be a 42” well, if this is true, filling it with bentonite would not be advised due to its diameter and proximity under the new highway. Can the contractor use excavatable CLSM as the plug? Can MDT locate and flag this well? Next; Well ID # 223420 is the nearest well on GIS to STA 321+66 but I believe this ID # is referring to a private well at a nearby home which will not be in conflict with the project. Additionally, Well ID # 334895 is the nearest well on GIS to STA 349+67. This Well ID # also appears to be a private well at another nearby home not in conflict. The two wells that need to be abandoned at STA 321+66 & STA 349+67 are easily found in the field adjacent to the highway. Can MDT provide the well information for these wells that are to be abandoned?

The project requires addition of approach guardrail terminal sections that would be necessary for two-way traffic in the crossover secetions. The guardrail summary also requires bridge approaches that would be necessary for two-way traffic, but they can not be installed permanently until after the bridge and approach roadway work is complete. Temporary guardrail, terminals, and bridge approaches need to be added to the project in areas that will have two-way traffic prior to the new roadway work getting completed.

For Call 204, Contract 02926, please clarify these remaining drawing and contract interfaces:
1. The October 5 answer changes 460.70 SQYD to Decorative Concrete 3 IN and supplies the color/pattern provision. Revised sheet 25 still labels the sloped-nose transition as UNCOLORED CONC. TRANSITION. Please confirm whether that transition remains uncolored/untextured, identify its limits, and confirm its payment allocation between the decorative-cap and median-curb items. We understand the new Desert Tan/Westwood Brown/Canyon Stone requirements for the decorative cap; this question concerns only the separately labeled transition.
2. The PSA on Section II page 18 of 29 incorporates an MOU dated May 2, 2025, while the attached MOU has 2020 signatures. Please provide the governing MOU or confirm which attached edition controls. The PSA header also shows September 27, 2026 and HSIP 5-2(183)51, rather than the current October 22 letting and HSIP 5-2(184)51; please confirm the applicable construction PSA.
3. PSA item 5 describes the 3% IPC fee against a consultant contract, and item 6(b) refers to a preconstruction project, although this PSA is expressly for construction.

1. The Median Island Sloped Nose transition is not to be colored or textured. The limits are shown in the detail on sheet # 25. Payment for this area for the curb will be made under Curb-Conc Median Type A, and the sloped cap, although uncolored, will be made under the Decorative Concrete – 3 IN bid item.

2. a) The MOU is hereby updated: MOU
    b) HSIP 5-2(183)51 was the preliminary engineering project number; HSIP 5-2(184)51 is the construction project number.

3. a). PSA item 5: The section is intended to define the contractors’ obligation on the project. The wording with the consultant was an error and should be considered the contractor.
    b). PSA Item 6(B): Similarly, the term preconstruction project was an oversight which should be considered construction project.

The signing plans for the Black Eagle NHS Routes-GF include symbols in the column labeled Breakaway Type that do not correspond with the symbols shown on S1. Can a reference key be provided to determine the type of breakaways needed? At least one location does not have any breakaway marking for the listed post.

Referring to question 2 can MDT provide more information about the wind dampener? Is there a detail available? What material is to be used, are vertical spacers required, is this a commercially available product?

We are reviewing the concrete scope for Call 206, Contract 26R26. Please clarify the following coordinated drawing and proposal items before pricing:
1. Proposal item 608010018 carries 1,471.00 SQYD of Sidewalk-Special Design. Plan sheet 39's thickened-edge location table is labeled in linear feet; its 13 rows sum to the printed 1,434.9 subtotal, but the table then prints a 1,471.0 total. The adjacent thickened-edge detail also says it is included in the unit price for 4-inch concrete sidewalk. Please identify the governing unit, quantity and payment item for those locations, explain the total adjustment, and confirm whether any area overlaps the ordinary 4-inch sidewalk quantity. Please provide a corrected schedule/detail if needed.
2. Proposal Section I page 5 says to limit sidewalk preparation to a minimum of 1,000 linear feet at any one time, then prohibits additional preparation until the new sidewalk is constructed and open. Please confirm the intended active-work limit and whether minimum is intended rather than maximum.
3. The Project Specific Agreement, Section II page 18 of 21, incorporates an MOU dated May 2, 2025. The attached MOU signature page, Section II page 17 of 21, shows May/June 2020 signatures. Please provide the governing May 2025 MOU or confirm the intended incorporated agreement, including the current Indian Preference compliance contact. We are not assuming a waiver of any reservation requirement.
4. For this contract, please identify whether the A or B measurement/payment provisions of June 2026 specifications 608.04/608.05 and 609.04/609.05 apply. The schedule separately carries street excavation and crushed aggregate course; please clarify which sidewalk/curb excavation and base quantities are included in those items versus the concrete unit prices so the same work is not priced twice.

For the fish screen, would it be acceptable if the screen can use a perforated plate with 1/8" holes. Perforated plate with 3/32" holes has become difficult to get and is twice the cost of 1/8" material. Most screens now use 1/8" with 40% open area.
