NOTE: If a specific style of Digger Specialties’ (DSI) decorative metal column has been selected, the Editor’s Notes include DSI Style Designations to facilitate editing. Simply use word search to find the style designation required; retain the ones required; and delete the others. If a specific style of DSI deco-rative metal column has not been selected but the basic column configuration is known, the specification text and Editor’s Notes will help the Editor select the DSI Style that is appropriate for the project. Be sure that the products selected are all available within a single style. If the Editor wishes to “mix and match” elements from different column types to create a “hybrid” column, verify with DSI the technical feasibility of the desired combination and whether the desired configuration will increase construction costs.
