Hammer, I was reviewing the load data on the new bridge beams, and I think we can cut the number of test lifts by rebalancing the support points. Got a minute to run through the numbers?

Sure, bring the numbers and let's see what we can do.

Here’s the quick rundown. The 25‑meter span currently has a live load of 45 kN per beam, with the supports spaced at 10 m and 15 m. The mid‑span is taking a 30 kN dead‑weight from the truss, so the total is 75 kN over that section. If we shift the 10‑m support slightly aft by 1.2 m and add a secondary tie‑rod at 12.5 m, the bending moment at the mid‑span drops from 560 kNm to about 410 kNm—roughly a 27 % reduction. That gives us a full test lift margin of 60 kN, meaning we can cut the lift count from five to three without compromising safety. All the calculations are on the board, so we can run a quick finite‑element check if you want.

Looks solid. Let's run the FE check and lock it in.Got it. Let's run the FE check and lock it in.

Running the FE simulation now—will push the updated report to the shared drive and lock the plan in as soon as it passes.
