Stich is 2m wide.
Initially we used 4m but replace the 4m by 2m+extension 1m.
To be sure 100%, can you find the pier drawing with the position of the stich starter bars.
Also , can you send me the PT drawings and the xls PT table before submission.
There were some problem in frame 20, there might be some problems on frame 16 too.
Best Regards
