21. Referring to existing site layout plan page, KEY NOTES 1 states that the contractor has to move the new rolling gate 5 (five) feet from the original location TOWARDS the facility to increase entry delivery truck turning radius.

21a. We are interpreting this as to move/install new gate 5 feet back / behinds original position. If this is the case, there are existing Cement Bollards on both sides of the entryway 3-5 Feet behind the gate. In this case do you want the contractor to remove the ballasts that are in the way of installing the new fence? Or do you want to leave existing Bollards and install new gate behind it (if that is the case then it will be approximately 6-8 feet behind original gate location and not 5)?

This is a minor item that can be field adjusted, for the moment, assume you will demolish the bollard out of the way.
