Q25: Plan Sheet 144 detail 2 shows the Art Installation Foundation. There is a note that states “Concrete is a temporary installation to be removed for art installation.” The detail shows a twin 20 ground mounted pole concrete foundation with a movable planter. Are we to install the pole foundation under a lighting line item, or does it get measured and paid under Art Installation Foundation (600011). What concrete are we demolishing for the art?

Q25 Response: The line item to be used is Art Installation Foundation (600011). The foundation includes anchor bolts which would typically receive the light pole. The anchor bolts will serve as the connection between the future artwork and the foundation. These anchor bolts should not be visible and therefore the contractor shall pour a layer of concrete on top of the foundation to encase the anchor bolts and therefor provide a concrete pad for the planter to sit on. Once the artwork is ready for installation, the concrete pad is demolished, and the anchor bolts are exposed for the art installation. Protect anchor bolts prior to pouring concrete. Unless the art installation is performed as part of this project, there is no demolition to be done.
