A: The AutoCAD files will be provided to the prime contractor upon award of the contract.
Q (No subject): There is conflicting information regarding the topsoil in Specification T-905. Please confirm which bid item will be used to Strip, Disc and stockpile and /or dispose of the onsite topsoil.
A: Topsoil obtained on site is intended to be obtained as a part of the unclassified excavation pay item; stripping, disc, and stockpiling and/or disposal of on-site topsoil shall be incidental to unclassified excavation.
Q (No subject): The typical sections on the Plans (C16-C18), Key Note 6 requires the placement of “4” Topsoil Salvaged from Excavation and Seeding (T-901)” No bid item or the T-901 Specification has been provided. How is the Contractor paid for the work required by Key Note 6?
A: The intention of Key Note 6 is for the contractor to place suitable unclassified excavation material prior to seeding. Addendum Number 1 will provide the following revisions: Specification P-152 will be updated to clarify the top 4-inches of unclassified excavation shall be reused as salvaged topsoil. Specification T-905 will be updated to reference Specification P-152 for topsoil obtained on site. Key Note 6 will be updated to reduce the salvaged topsoil depth from 4" to 2". Specifications P-152 and T-905 will be updated to clarify that no separate measurement or payment will be made for placing salvaged topsoil, salvaged topsoil shall be considered incidental to P-152 Unclassified Excavation.
Q (No subject): • Specification 905-4.1 Method of Measurement states “Topsoil obtained off the site shall be measured by the number of square yards of topsoil measured in its original position and stripped or excavated. Topsoil shall be measured by volume in cubic yards computed by the method of end areas.” Specification 905-5.1 Basis of Payment states “Payment will be made at the contract unit price per square yard for topsoil (obtained off the site) placed at a minimum 2-inch depth. This price shall be full compensation for furnishing all materials and for all preparation, placing, and spreading of the materials, and for all labor, equipment, tools and incidentals necessary to complete the item.” The bid form has a bid item for Topsoil (Obtained Off Site) by the square yard. Key Notes 5 in the plans calls for 6” Topsoil T-905, and Key Note 6 in the plans calls for 4” Topsoil Salvaged from Excavation and Seeding. Please confirm the intent of the Bid Item Topsoil (Obtained Off Site).
A: Topsoil obtained off site is intended to be used as the grass filter strip off the edges of the new runway and taxiways. The intention of Key Note 6 is for the contractor to place suitable unclassified excavation material prior to seeding. Addendum Number 1 will provide the following revisions: Specification P-152 will be updated to clarify the top 4-inches of unclassified excavation shall be reused as salvaged topsoil. Specification T-905 will be updated to reference Specification P-152 for topsoil obtained on site, and will revise the minimum depth of topsoil placement to 6 inches to match Key Note 5. Key Note 6 will be updated to reduce the salvaged topsoil depth from 4" to 2". Specifications P-152 and T-905 will be updated to clarify that no separate measurement or payment will be made for placing salvaged topsoil, salvaged topsoil shall be considered incidental to P-152 Unclassified Excavation.

Q (No subject): Specification 101-4.1 Method of Measurement for Pavement Pulverization states “The unit of measurement for pavement removal shall be the number of square yards removed from Airport property by the Contractor at the depth specified in the plans.” It appears the intent of the plans is to pulverize the existing runway, then place approximately 1/5th of the material in the South Access Road disposal area, and not removed from the Airport property. How is the Contractor paid for the embankment of the grindings on the South Access Road? Is the intent to pay the Contractor to pulverize the asphalt and leave it in place with Bid Item A-26 then to pay the Contractor Unclassified Excavation A-36 to either embank the grindings or export and dispose of them?
A: The intention for the pulverization bid item is for the contractor to pulverize the existing asphalt and base, use the pulverized material to construct the access road, and dispose of excess pulverized material off site. The P-101 specification will be updated as a part of Addendum Number 1 to clarify the intention of the bid item.
Q (No subject): Reference “Taxiway B1 Typical Section” on plan sheet C17. Key Note 7 directs the Contractor to “Pulverize Existing Asphalt Base 6” Depth. Place as Borrow (P-101) per Access Road Disposal Site Plan or Dispose at Approved Offsite Location.” Performing Key Note 7 will result in a void. Please confirm the Contractor will be paid per Key Note 10 to Place “Suitable Excavated Material (P-152) or Subbase Course (P-154) as needed for Subgrade Elevation” to fill that resulting void.
A: The intention for the pulverization bid item is for the contractor to pulverize the existing asphalt and base, use the pulverized material to construct the access road, and dispose excess pulverized material off site. The Contractor shall place suitable excavated material in all areas with a void, imported P-154 is not anticipated to be needed to be needed to construct fill areas. Key Note 7, Key Note 10, Taxiway B1 Typical Section, and the P-101 specification will be updated as a part of Addendum Number 1 to clarify the intention.
Q (Wetland Mitigation): Can a plan sheet or Specification be provided to define the extent of the Wetland Mitigation scope?
A: Addendum Number 1 will remove the Wetland Mitigation bid item.
Q (Engineer/RPR Field Office): Spec section 60-05 indicates no Engineer/RPR field office is required. Spec section 105-4 indicates the field office is required. Please clarify if an Engineer/RPR field office is required.

Q (South Access Road Keynote): Per the "South Access Road Disposal Area Typical Section" on sheet C18, callout 19 is used. There is no detail given in the keynotes for callout 19. Please confirm if this should be callout 18.
