Question List
Subject: Pavement Operations Type: Specifications
Question Date: 9/21/2018 4:20:47 PM
Will VDOT allow the contractor to perform the type II joint repair patches in the existing surface and pay for all material necessary? As the bid proposal currently reads, the contractor must mill off 2.5” of existing asphalt, perform any type II patching and joint repairs, and overlay with 1” of SM-9.0E (HP) in the same work shift in order to meet the requirements of 31.5.05(c) (No variation greater than 2” between adjacent lanes). Furthermore, has the Department considered that anywhere that the roadway is sloped toward the Express Lanes will need to be a “mill & fill” (two lifts) to mitigate ponding concerns between paving shifts and the impact that this will have on the rideability of the final product?  
Answer   Date: 9/24/2018 3:42:05 PM
All Type II and Type III patches are to be performed on the existing surface before milling and paving for surface mixes. Schedule and sequence of paving is left for the contractor to determine.  
 
Subject: 2018 Temporary Pavement Markings Type: Specifications
Question Date: 9/20/2018 9:13:16 AM
The 2018 patching tables indicate significant areas being repaired that will require temporary Type A pavement markings. Will Vdot assume responsibility for the maintenance of these markings during the winter months?  
Answer   Date: 9/21/2018 11:08:50 AM
Yes, VDOT will assume the responsibility for maintenance of the temporary markings during the winter months.

Question Date: 9/20/2018 9:05:31 AM
Will Vdot issue partial acceptance for the 2018 work? Some of which will result in a coarse aggregate riding surface that will be exposed to winter weather and traffic for several months prior to completion of this project?  
Answer   Date: 9/20/2018 4:04:21 PM
VDOT accepts coarse aggregate riding surface that will be exposed to winter weather and traffic for several months prior to completion of this project.  
 
Subject: Milling Type: Proposal
Question Date: 9/19/2018 2:59:28 PM
Is there data available to show locations of existing joint fabric that may be encountered during milling operations? If those locations have fabric that span multiple lanes, the milling machine could pull the entire length of fabric and compromise the pavement in the adjacent lanes. How would Vdot compensate for this contingency?  
Answer   2 previous answer(s) Date: 9/20/2018 4:04:00 PM
Fabric could be encountered along some of the transverse joints (not all), but we do not have record of the exact locations. Most of the bad transverse joints will get deep patching (Type III) which includes full depth saw cut through asphalt and PCC, so any fabric extending to express lanes will be saw cut. We anticipate any remaining fabric will be milled out without compromising the adjacent lanes.  
 
Subject: Sequence & drainage Type: Specifications
Question Date: 9/14/2018 1:12:25 PM
In cn515-000100-02 Section III.A.1 on page 6 of the spec book it states “Performance pavement planning may be performed in multiple lanes across the entire widths of the lanes up 4 miles of travel lane unless otherwise stated in the Contract. Performance travel lanes surfaces must be paved back within 96 hours from the end of the performance planning operation.” On pages 193 & 195 in the sequence #2 it states “mill 2.0” full lane length and replace with 1.5” SMA-9.5E(HP) and 1.0” SM9.0E(HP). From the statement in the sequence can we assume that you want the entire lane milled from start to finish before the adjacent lanes are milled & paved? In SP515-000100-00 section III.A.1 2nd paragraph it states “the extent to which the interior lanes shall be planed will be such that the planed portions can be repaved within the work-zone time limits unless provisions are made to mitigate the ponding of water (i.e., milling adjacent lane(s) and shoulder or cutting drainage outlets through the shoulder).” With both of these scenario’s there will be an issue with the hot lanes and adjacent lanes. If the contractor chooses to mitigate the water by cutting outlets then when the hot lanes or the newly paved lanes are on the low side of the supers, the cuts will have to go thru the hot lanes or the newly paved lanes. Is this the intention & will this be allowed? If the hot lanes or the newly paved lanes are on the high side of the supers then water will still pond because the new paving raises the elevation of the roadway by 0.5”. Will the Contractor be responsible for the ponding water in the case of the hot lanes or newly paved lanes being at the top of the super?  
Answer   Date: 9/21/2018 11:07:19 AM
We intended to say "Mill the entire pavement surface including the patched transverse joints to 2.5 inches and replace with surface mixes". We did not intend to ask the contractor to mill and pave one entire lane from start to finish before the adjacent lanes are milled and paved. We leave it up to the contractor on how to schedule and sequence the mill and pave operations. We do not anticipate the contractor to cut through the HOT lanes. Revision has been issued to update accordingly.  
 
Question Date: 9/20/2018 8:38:38 AM
Could Vdot please provide a detail in the special provisions to address how the new proposed profile will tie in to existing pavement.  
Answer   Date: 9/21/2018 11:08:09 AM
By answering this CABB question, we revise the proposed milling depth to 2.5 inch so that there is no change in the profile. Addendum will be issued to address.  
 
Subject: Award of Contract Type: Specifications
Question Date: 9/4/2018 2:47:09 PM
With the need for part of the Type II & Type III Surface restoration to be completed by 12/7/2018. When will the Award Recommendation Letter be issued by the Chief Engineer per Accelerated Award (section 103.02) (SPCN on page 9 of Contract Book)? What date will VDOT guarantee to have the Contract Execution assuming the Contractor submits the required bonds & insurance certificates within the 7 days (per SPCN on pages 9 & 10 of Contract Book) and Contractor executes & returns the Contract within 7 days of receiving it from VDOT? A set timeframe for the answer to these questions is critical to know the amount of time available, therefore the amount of resources needed to complete the Type II & Type III Surface Restoration required by 12/7/18.  
Answer   1 previous answer(s) Date: 9/5/2018 2:06:12 PM
Due to the apparent contract value and required action by the CTB the earliest possible date for contract award and execution would October 31st.  
 
Question Date: 9/6/2018 8:46:13 AM
With October 31st being the earliest possible date for Contract Award, how will liquidated damages be handled/assessed for the Type II & Type III patching that is to be done by 12/7/18? How will delays in award be handled since the 10/31/18 earliest award only gives the contractors 36 calendar days and really there are only 31 because we will loose 5 days for Thanksgiving & that weekend unless the contractors will be allowed to work? Will weather/environment (rain, snow, temperatures below 40 degrees) be taken into account in assessing liquidated damages?  
Answer   Date: 9/20/2018 4:15:29 PM
Addressed via addendum dated 9-14-2018  
 
Subject: PROPOSAL Type: Proposal

Answer   Date: 8/28/2018 4:19:58 PM
The proposal has been corrected.
