Sounds like your study of the NOTAMs wasn't as thorough as it might have been. Sorry if that sounds unduly harsh.
In particular the reason for the 737 landing long:
E)DURING DISPLACED THR RWY 05/23 OPR, BEGINNING OF LDA FOR DISPLACED
THR SHOWN BY BLACK AND WHITE MARKER BOARDS AT EDGE OF RWY.
BEGINNING OF TORA/TODA/ASDA FOR DISPLACED THR SHOWN BY ORANGE AND WHITE MARKER BOARDS AT EDGE OF RWY.
and the reason for your delay that had "something to do with boards"
E)DURING RWY WIP THE RWY WILL BE CLOSED 10 MINUTES PRIOR TO
IMPLIMENTATION OF REDUCED DISTANCES AND 10 MINUTES PRIOR TO REMOVAL OF REDUCED DISTANCES
