After our initial review, there is a discrepancy between the cross sections and the dirt run provided. The excavation quantity appears to be short by roughly 23,000 CY. Please review the two documents and verify which one is correct.
Answer
Submitted: Thursday 30-JAN-2025 09:39 AM
The grading quantities shown on the cross sections were tabulated independent of any additional grading quantities for approaches, topsoil replacement, ditch grading, etc. The quantities for grading included in the summary frames, earthwork log file and mass diagram include the additional grading quantities and are correct.

Looking for clarification on the answer to question 3. We included additional grading in our initial review. From station 1799+50 to station 2134+00 there are 219 areas that have greater than 5 CY difference between the dirt run and cross sections. With a total difference of 23,179 CY more excavation and 17,464 CY more embankment in the cross sections than the dirt run. I also noticed in the dirt run it stated skip station range twice between 1934+50-1936+00 and 1890+50-1892+00 leaving out 256 CY of excavation and 7,674 CY of embankment that is called out in the cross sections. Those quantities are included in the total difference stated above. The design files MDT provided also match with the cross sections making the dirt run the odd document out. MDT also stated in the answer to question 3 the earthwork log file and mass diagram are correct; however, the mass diagram shows 3,409 CY of more excavation 3,248 CY less embankment and 6,657 CY more excess material than earthwork log file. Please review the grading plan quantities.
Answer
Submitted: Monday 03-FEB-2025 10:57 AM
The quantities shown on the cross sections are in error and should not be used. The process that was used to generate these quantities for the cross-section sheets is an additional process that is picking up additional components, especially in the areas where PESC features are shown on the cross sections. That same additional process is not leaving out the skip areas for the bridges, which translates into additional fill volumes presented on the cross sections. Whereas the process used to generate the log file and volumes presented in the summary frames omits those skip areas properly. The mass diagram does not quite match the log file and summary totals as stated in the question and has been corrected. Updated earthworks log file, grading summary total and mass diagram which reconcile with one another are linked below.

The Excavation – Unclassified (203020100) quantity has been updated to 738,625. An amendment will be issued, updated bid files will be posted. UPDATED SHEET 11

For the construction of the 2 bridge sites on this project, would the use of the Clearcast transparent decking system be allowed for use by contractors vs form/strip? This system would function as stay in place decking but allow visibility for MDT to inspect the bridge deck from the underside. It would also allow for concrete consolidation inspection during deck pours.

There are 524 Single metal panels listed in the proposal for this project. Is this correct?
Answer
Submitted: Friday 07-FEB-2025 06:50 AM
Yes, this is correct. The quantity can be attributed to the number of right-of-way breaks, approaches, cross fences, straight runs, etc., which all require additional single panels per the Detailed Drawings.

Looking for clarification on the answer for Question #7: The state has indicated that the large number of Single Panels can be partially attributed to the number of R/W breaks…”which all require additional single panels per the Detailed Drawings”. There are no detailed drawings for metal R/W breaks and to consider R/W breaks the equivalent to two single panels is misleading and creates confusion for MDT inspectors on payout for these items.
1. Will the state include a detailed drawing for metal R/W breaks as well as create a new bid item for both wood and metal Right-of-Way Breaks? Wood R/W breaks are built with two single braces with treated 2x6s bolted to the posts spanning the gap between the braces [MDT 607-20] so as to not disturb property monuments. For metal R/W breaks we recommend filling the gap with something like woven wire to avoid drilling holes in the metal posts.
2. Will the state identify the planned quantities of R/W breaks for this project?
Answer 
Submitted: Thursday 13-FEB-2025 02:20 PM
1. No, a separate drawing will not be provided.  For the bid items Farm Fence-Panel/Single (Double) FM, the FM indicates metals panels.  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.

2. There are approximately 200 R/W breaks on this project.

1. The individual structures are identified by a hatched pattern shown in the plan on Sheet B2.  The CONSTRUCTION EQUIPMENT ON STRUCTURES Special Provision applies ramp structures (01754 & 01755) and overpass structure (04771).  Per the Special Provision, structural analysis for this project is required for equipment using outriggers, equipment beyond legal load limits and equipment not listed or operated according to MDT’s Approved Construction Equipment List (ACEL.) 
2. Yes, the median curb will be tied to the existing structure per Detail Drawing  609-10 as modified in the attached drawing: DETAIL DRAWING

The intent is to dowel the curb into the deck 3.75”.  The Contractor will be responsible for locating rebar prior to drilling into the existing bridge deck.

Please reference questions and answers #2. It is important to note that there is a difference between sign mounting hardware and sign mounting brackets. Hardware is not available that will adjust the clearnace of the sign from the overhead structure. New sign mounting brackets or revisions to existing sign mounting brackets could provide that function. What requirements will be enforced in doing so? Special provision 50 is the standard provision used when a overhead sign bridge is installed on a MDT project. It requires, as part of the design by a registered professional engineer, the information related to the sign mounting bracket system used. Will the contractor be responsible for hiring a professional engineer to design the new mounting system and to verify it complies with the original design of the this structure when it was installed? Can the Department provide the initial design information submitted when this structure was installed?

This response replaces answers #3 and 4 in the response to Q&A #2.

The single sign on the WB offramp will be divided into 2 signs.  Plan to mount the signs using the existing brackets and hardware.  Sign design calculations will follow project award.

Please reference plan sheet 43 and the guardrail summary on sheet 22. The first two lines of the guardrail summary appear to represent the guardrail run on the SE corner of the Zoo Dr bridge, south to the EB on ramp. The end station of the first line matches the beginning station of the second line equating to a continuous run which matches what is shown on sheet 43. However, there are 3 end sections between both summary lines. There can only be two unless the run is spit into two in which 4 ends would be required.

If the One Way Dept Term is eliminated, please confirm that the rail extending east on the EB on ramp only extends 25ft beyond the radius rail. If that is not correct, the Intersecting Roadway Terminal will not work at that location. Please provide more information for the full layout of the guardrail run including the length between the bridge and the radius rail as well as the length of rail after the radius rail on the EB on ramp.

The MGS one-way departure terminal section should not be shown after the IRT.  The IRT section has an anchor section that extends only 25 feet beyond the radius rail.

The sign design and signing plans for the overhead sign on the WB offramp have been revised (divided the overhead sign into two separate signs). The new sign dimensions are very similar to the existing sign dimensions, as shown below:
Existing signs: 14.5'x 6’ and 10.5'x6’
New signs: 14'x 6’ and 10'x6’”
The updated sign design files can be viewed here: SIGN CALC SHEETS
The updated signing plans can be found in the link in Clarification #4.
The requested files 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, change ordered work, or changes that are made during construction to fit field conditions.
UPDATED: Tuesday 11-FEB-2025 10:38 AM
In addition, the Department will not make any revisions to the electronic files prior to award; changes needed via change ordered work, or changes that are made during construction to fit field conditions will be provided at that time per the requirements of Subsection 619.03.2.

Phases and contract time.
Agree, not enough time and also phases issues (through signal work). Other work/materials supplies are not available (at best) until mid to late September. 40 days additional is requested.
As far as signal work, would MDT be open to supplying salvaged signal standards, arms, and signal indicators to facilitate new lanes until new materials are available? Paid under misc work?
Answer
Submitted: Friday 14-FEB-2025 09:10 AM
1. See the answer for Q&A #11, additional time has been granted.
2. The Contractor may temporarily use electrical equipment that is removed and salvaged from the project.  The equipment must then be removed and salvaged in accordance with the electrical plans and the revised Special Provision for REMOVE AND SALVAGE MISC ELECTRICAL.  The Contractor is responsible for repairing or replacing damaged equipment.  This work is not eligible for separate payment.

Overhead structure procurement processes include investigative drilling, preparing logs of boring, structure design, foundation design, review, approval, fabrication, and delivery. The sum and sequence of these processes has taken over a year in the past. In the event all other work is finished by 11-15-25, and the Contractor demonstrates timely facilitation of all procurement processes, but overhead structure delivery does not permit installation by 11-15-25, how will the Department address additional time necessary for their erection and installation of associated appurtenances? Will the Department allow use of boring longs provided in the proposal for overhead sign structure foundation design? Will any necessary investigative drilling be allowed to commence prior to the June 9 NTP and how will the Department address the time needed.
Answer

1. The Special Provision LARGE LEAD ITEMS is hereby incorporated into the contract.
2. Boring logs provided in the proposal cannot be used for overhead sign structure foundation design.  Location specific boring logs for each foundation of the overhead sign structures is required.
3. Upon award of the contract, a Change Order will be issued to adjust the Notice to Proceed date to allow for required investigative drilling for foundation design and associated traffic control (if necessary).  No other contract work may begin prior to the original Notice to Proceed date of June 9, 2025, without the written approval of MDT’s Engineering Project Manager.

Is the intent to extend the 12x8 culvert prior to the ditches being turned on? When can we anticipate the ditches being turned on?
Answer
Submitted: Friday 14-FEB-2025 02:25 PM
1. The NTP for this project does not allow for the 12x8 culvert extension to be completed prior to ditches being turned on.  If the contractor has a way to get the extension in prior to the NTP, bring it the Project Manager for discussion.  Otherwise, plan to work around the extension until it can be completed.
2. The irrigation date is April 1^st; after that date, the contractor needs permission be in the ditch.  April 1^st is generally conservative; if written permission is granted by Canyon Creek Ditch Company, the contractor could work beyond April 1^st.

Casing used to construct the sign bridge drilled shafts can be left in place if approved by the design engineer.  If casing is left in place, it is required to meet specifications for Permanent Casing (558.03.07).
UPDATED: Tuesday 18-FEB-2025 11:30 AM
Casing used to construct the sign bridge drilled shafts can be left in place if the contractor’s foundation design engineer specifies this.  If casing is left in place, it is required to meet all requirements associated with Permanent Casing.
