Six Degrees of Exploration REUSE Find reusable item Explore evolution history : UP : Concepts DOWN : Detailed designs SIDEWAYS : Alternatives Explore project context : UP : Bigger chunks DOWN : Smaller details SIDEWAYS : Related items KNOWLEDGE

Proposed Process (Corporate Memory) REUSE Find reusable item Explore evolution history : UP : Concepts DOWN : Detailed designs SIDEWAYS : Alternatives Explore project context : UP : Bigger chunks DOWN : Smaller details SIDEWAYS : Related items KNOWLEDGE

Evolution History Explorer Metaphor : Storytelling ,[object Object],[object Object],[object Object],I called MCC and got information for items 1&2. For item 3, MCC requires top of the supporting steel frame/bottom of cooling tower unit to be 3 to 4 feet above the roof. Using this as guideline, we will put T/Stl for our supporting From phone conversation with Erich Swett on July 25, 2000 Cooling tower weight is 30,000 lbs per unit. there may be one or two units. A screen will occur all around the tower. To support this screen, the four columns at the North west of the central plant will be extended. the dimensions of the cooling tower is, 14' wide (NW to SE) by 22' I have a follow up comment. You said that you the top of steel elevation at the cooling towers will be 22'-2 1/2". It second glance it looks like this dimension should be the bottom of steel elevation.
