Submitted Questions for Job 22616 - NH-3-001(031)201 & NH-3-001(033)200

In the special provisions Asphalt Stabilized Base Course, basis of payment, it states to included the cost of Portland Cement in the contract unit price for "Asphalt Emulsified Base Course". There is no way quantitfy the amount of cement needed in that item with no design done prior to bid opening. Can a pay item for cement be included in the bid form?

DOT Response

Response from M&R:  During the mix design process for the Asphalt Emulsified Base Course, cement may be added to the material if the representative specimens are not meeting the requirements set by the parameters of the special provision. Due to the mix design potentially not requiring the addition of cement, or if so, could vary on dosage, there is no pay item set for this and is incidental to pay item for Asphalt Emulsified Base Course.

The supplemental data files provided for the projects are the same for both job numbers (23109 & 22616), the data for both folders is 22616 data and we are missing 23109.

DOT Response

Supplemental Design Date for 23109 was moved and available now in the Job 22616 folder with the file name 23109_Supplemental Design Data.zip

Job #22616 has Approach Foreslope Reconstruction - LI #16 - 203 0215 has a quantity of 36 EA. Plan Sheet 20-4 provides a table with a quantity of 25 EA. Which is correct or is it assumed that 11 EA will be done as decided in the field? This is tough to quantify quantities needed to do this not knowing the measurements at the locations. Please provide clarity on the quantities for this item.

In the phasing plan, you are prescribing that 1 lane of the road has to be complete up to asphalt pavement before work on the other lane begins. This will result in 2 mobilizations for all crews on the project including the asphalt plant likely affecting your project cost. Traffic will have to run on the work surface at night even in this scenario. Is there a reason the contractor can't incrementally work the road full width with a pilot car operation? This is how most reclamation jobs are completed.

DOT Response

The intent of the phasing plan is to show what has to happen on each half of the road. If desired, both halves could be worked on using the pilot car prescribed for the operation. The primary limitation will be to finish paving locations based on the timelines outlined in Special Provision 542(22). 

Traffic will be driving on the working surface as is noted. Incremental construction should work out as noted and would be coordinated and detailed during the preconstruction meeting.

Project NH-3-001(031)201 (Section 6 Sheet 3) - Plan note 754-P02 shows the Light Emitting Diode Stop Signs to be costed under Bid Item #68- Flat Sheet for Signs Type XI Sheeting. Should these have there own bid item as they will distort the SF pricing of the XI Sheeting? Usually the Solar Powered Blinker signs have there own bid item to cover the actual costs.

For the variable Aggregate Base Course, Cl 5 shown on Plan Sheet 10-1, Full Depth Reclamation Table labeled (A) = 21,318 ton discretionary if depth increase of less than 2 inches, does the Department intend to survey and blue top the finished Asphalt Emulsion Base Course (with fog coat) in order to determine the depth of ABC, Cl 5 necessary throughout the entire project length prior to paving? The ABC, Cl 5 depth could vary from 0" to 2" on top of the finished Asphalt Emulsion Base Course (with fog coat). What is the tolerance for this? What will prevent the thinner sections from sliding around and not staying in place, while also having the strength to pave over? Should a prime coat be considered on top of the ABC, Cl 5?

DOT Response

The discretionary aggregate is intended to be added following the reclamation (before asphalt stabilization). "Construction Requirements" A. General, 1. Order of Operations, of SP 542(22) calls out order of operations. Addition of discretionary aggregate per Paving Table Subnote "A" on plan sheet 10-1 would occur during the "initial grading the reclaimed material to profile" as needed to get to the proposed profile surface. Surface tolerance is identified in "Construction Requirements" B. Reclamation, 3. Surface Tolerance, of the same SP. 

 

Grading and finish surfaces are included in the supplemental design data and would facilitate grading operations. Bluetops could be set pending survey requests for the data or check shots could occur following machine control as needed to verify grade.

For the variable Aggr Base on shoulders per Plan Sheet 11-8 thru 11-18 = 2595.21 ton, does the Department intend to survey and blue top the shoulder in order to determine the final grade and actual quantities necessary after milling?

DOT Response

Grading and finish surfaces are included in the supplemental design data and would facilitate grading operations. I would assume bluetops could be set pending survey requests for the data or check shots could occur following machine control as needed to verify grade.

Addition of aggregate to facilitate establishing grade would likely be easiest following all reclamation activities (prior to asphalt stabilization).
