3.3 INSTALLATION
A. Follow manufacturer’s detailed instructions for installation of modular base system and floor panels [including ramps as shown on Drawings].
1. Mark each floor panel on top surface with its alpha-numeric grid locator designation using a large indelible marker.
B. Install [concealed] [exposed] wood skirting at sides of exposed wells and ramps.
C. Sequence of Operations: Coordinate installation of modular base system and floor panels with Section [16125] [ ______ ] to provide for simultaneous installation of power and communication system wiring with access floor system.
D. Cut openings in floor panels as required for power/communication outlets.
