The required pH for furnished topsoil is between 6.0 and 8.0 per Subsection 713.01.

Since the pH for the existing topsoil on the project is between 5.5 and 5.8; can the specified pH for furnished topsoil be modified to match the existing topsoil pH, and reduce the cost of imported topsoil to be furnished?

This will be addressed under a forthcoming amendment.

The physical data for the Akupini and Windy Creek bridges show a legal load of 36 tons for a Type 3S2 Truck. Is that the payload or the payload and the weight of the truck together?

A typical loaded Type 3S2 truck would be closer to 46 tons gross weight. If the gross weight of 36 tons is the max allowed it would increase the amount of truck loads by as much as 50%.

Please clarify the max load allowed over the bridges.

Yes, regarding the 3S2 truck, the structure load rating details shown in the bridge inspection reports is the truck with total weight and axle loads including truck and payload. This is standard legal load rating vehicle from the AASHTO Manual for Bridge Evaluation for load rating purposes. The bridge is not posted for restricted load, and is open to legal hauling. Any overload or permit vehicles will need to be evaluated for capacity.

Section 108.01 paragraph f limits the work at Many Glacier Hotel look road, parking lot, and horse pedestrian/bridge: and Entrance Station construction work to September 21st , 2020 to May 28th 2021. Paragraph g limits all culvert replacement work from the third Monday in September to the third Monday in May of any year.

The temperature specification for beginning asphalt paving must be at least 55 degrees F. In looking at historical temperatures it appears that the temperature may not be within asphalt paving ranges during the times specified, and if it is the allowable paving temperature window will be extremely short during the day. Can the paving low temperature specification be reduced for paving within those timeframes?

This has been an issue on other FHWA projects.

We’re not sure where you’re seeing the 55 degree F temperature specification for paving. Weather limitations for paving are shown in Subsection 401.07, and will not be changed.
