What will be the procedure for concrete and asphalt trucks to gain access to the airfield work sites?

An airfield free work zone will be created for the contractor to freely work within the construction boundaries at the site. Any need to leave the free work zone must require an escort.

4. Where will Contractor employees be permitted to park?

a. See attached map with permitted parking areas. When conducting work at Ramp 1 near spot 4 we will have spots 4 and 5 blocked off as a Free Zone and the contractors could park inside the free Zone area or next to the 41st APS facility on the north side of the building depending on how many vehicles are involved.

8. Please confirm that once the cause of the erosion underneath the existing asphalt is determined that any additional required work will be sufficient justification for a Contract Modification.

12. Can we soil-cement the dirt under the concrete instead of digging out the dirt and hauling in limestone?

a. Contractor must install aggregate subbase.

16. Please specify joint filler? Will cork or rubber expansion be acceptable or is this a liquid product only?

a. Joint filler shall be hot applied fuel-resistant rubberized asphalt joint filler.

18. Could you please clarify the deformed dowels you wish to install? Our experience is that the dowels will be smooth to allow expansion contraction but not up and down movement

a. Contractor should use regular, non-deformed dowels.

a. Existing concrete is 9 inches thick +/- 1 inch in some areas.

27. Drawing page 9 of 9 shows mooring eye shaft (copper rod) driven into the ground 8', however, at the bottom, there is no auger or any other device attached.

a. Auger shall be attached to mooring shaft for plane stability.

28. Are there any Geo tech reports available?

a. No, there are no geotechnical reports. There is a brief evaluation of the subbase from the last pavement condition survey which states: "The subgrade soils around the airfield mostly categorize as Eustis loamy sand according to the United States Department of Agriculture (USDA) Web Soil Survey. These soil types are composed of varying degrees of silts, clays, and sands at varying depths, with sands typically comprising over 80 percent of the mix."
