There are several ways to influence the content of ACI standards, such as code requirements and specifications, and other ACI documents. The first opportunity is by becoming a voting member of document-producing committees. Others include participating in the Technical Activities Committee review process, making a public comment on a standard, or reporting errors and omissions. ACI members also have a chance to change documents by using the appeals process

Deflection data from 56 large bridge spans are presented. The plots show that deflections plotted against time in the logarithmic scale evolve systematically as a straight line. Also, the deflections of 33 of the 56 spans become excessive in less than 40 years, and the deflections of 20 of the 56 spans become excessive in only 25 years. The authors call for an improved creep model to allow for sustainable design of structures of high creep sensitivity

We placed some No. 6 vertical bars at a slight incline in the first lift of a wall placement. The protruding dowels are now too close to the wall forms for the next lift. When the horizontal bars are placed, we have little allowance for movement of the forms and we can’t meet the clear cover tolerance. The contract documents permit cold bending of No. 6 bars, and we have approval from the Structural Engineer. We planned to bend the verticals with a hickey bar, but the Inspector told us we couldn’t create a bar slope greater than 1 in 6 when doing this. I’ve never heard of this rule and can’t find it in any ACI documents
