Question # Question Answer

During the site visit on 8/3/23 the existing patrol road to be relocated appeared to be a mixture of gravel and organic material/grasses rendering it an unsuitable material based on Plan Sheet CD101 (Note 2) which states that the contractor may reuse existing patrol road aggregate to construct the proposed patrol road as long as proper precautions are taken to keep aggregate clean from underlying organic material. Should we assume all new aggregates for the relocated section of the patrol road?

It is the intent that the Contractor can reuse the existing material as much as possible. If the material is contaminated with existing organic material or it occurs as a result of the Contractor’s operation, new crushed aggregate base course will need to be provided by the Contractor. The area of the patrol road that will be relocated has minimal reusable gravel.

Plan sheet GC141 States Work Areas 1 & 2 can be completed concurrently. It also states that Work Area 1 shall be completed in 80 Days and Work Area 2 shall be completed in 21 Days. Please confirm that Work Areas 1 & 2 when performed together shall be completed in 101 Days with the work in area 2 to be limited to no more than 21 Days within the overall 101 Day duration

Work Areas 1 and 2 will have 106 Calendar Days to complete the work. Work Area 1 has 80 days, Work Area 2 has 21 Calendar Days + 5 nights. All work within Work Area 2 disturbing the existing runway shoulder which includes grading, excavation, and backfill and paving with appropriate materials shall be completed within that original 21 days. Once the concrete pavement and asphalt has fully cured out, 5 additional nights will be allowed to finish the electrical installation, pavement markings, joint sealing, etc. that would have affected the regular runway operations.

If Phase 1 (Submittal Phase – 180 Calendar Days) is completed earlier, will bidding contractors be allowed to use the extra time saved in Phase 1 and apply to the Phase 2 construction phase?

365 days is for both phases; and if phase 1 is completed earlier than projected that would allow more time for phase 2

4 Will an option for electronic bid submission be allowed? All bids should be either mailed or dropped off in person prior to bid opening.

Since the HCP & Access Road intersect, what are the limits of grading that should be included in Item 0001 – Construct Hazardous Cargo Pad (in the event that Item 0004 – Construct Paved Access Road is not awarded)?

If Item 4 is not awarded, the grading will be updated appropriately to tie into the existing ground to remain approximate near STA 56+00. If the access roadway is not constructed, the roadway “berm” and culvert pipe will not be needed. The underdrain outlet pipe will need to have an endwall installed in the bank similar to the other underdrain outlet pipe and endwall at STA 19+61.68 OFF 360’.

Detail 2 on CP302 and Detail 2 on CU521 do not match. CP302 shows the shoulder CABC bottom extending below the bottom of the stabilized drainage layer edge and CU521 shows the bottom of the CABC matching the top of the stabilized drainage layer. Please clarify.

Shoulder pavement section shall be constructed as shown on Details #1 and #2 on CP302. The depth of the CABC will be determined by the width of the shoulder awarded.

The callout indicating “15” to 22.5” ABC does not match the detail, as the ABC is shown at the top of the drainage layer. 15” also does not match details 1 & 2 on CP302 (7”). Please clarify.

Shoulder pavement section shall be constructed as shown on Details #1 and #2 on

CP302.

The shoulder CABC thicknesses do not match the 5% slopes shown for the shoulder subgrade. Should 7” (or 15”) be used as the outside edge thickness or should the 5% grade be held?

The Crushed Aggregate Base Course shown in Details #1 and #2 shall be offset from

HMA Surface by 2 FEET not 2 INCHES as stated on the details.

The intent is that the CABC material is graded to drain back to the underdrain trench at .5% not the 5% as stated on the details. The depth of CABC computes correctly if using the .5% instead of the 5% slope.

33 What is the depth of the existing aggregate on the patrol road?

Portion of patrol road that will be relocated has minimal gravel that is suited for reuse.

34 Is there a disposal area for excess soils and 1500 cy of unsuitable soils?

The base will (at the discretion of the contracting officer) accept suitable soil stockpiled for future use and will allow spreading of soil with appropriate erosion control in designated areas.
