What Were the Causes/Costs/Explanations for each of the Bellview Library Change Orders?

Ahead of yesterday's BCC meeting, there were some voices online and other places that were questioning the size and number of change orders necessitating approval by the board to keep the Bellview Library project on track.  This build out has been costly due to a number of factors--some unforeseen--some self-inflicted.  Nevertheless, the board did approve the change orders by a unanimous vote as the consent agenda was approved.  I had a one-on-one meeting with the Facilities Department and the project manager--and we went through each change order--why they were needed and why the costs shook out the way they did.  Below is a summary of each of the change orders approved and a short explanation of the "why."  I provided this information to each of my peers yesterday before the meeting so they would have awareness prior to the vote.
