QUESTION 9: Item X4023000 Temporary Access Road 1 EA- Can the length be clarified for how much temp roadway we are responsible for building with this item?

RESPONSE 9: This pay item is based on the contractor’s means and methods during the phasing of the construction and would only apply if conditions would prohibit the opening of the road within the pavement limits at the end of the working day.  As such, it is paid only under the circumstances where a temporary access road would be required for residents to get to their homes.
