The card also lists phone numbers for Bridge Engineering Section experts to consult with questions. Operations Managing Engineer Bob Thompson suggested producing such a guide. Bob Fuquay in Records Management helped Bridge Engineering Section staff develop the item through a private contractor. Since the cards will be carried around in pockets, developers made sure they will survive a trip through the clothes washer and dryer. Fuquay tested the scratch-resistant lexan card in boiling water and a microwave.
Some bridges now get checked every day, so staff members expect the cards to get heavy use.
