Hi! I have conducted a traverse in two parts; pre-construction and post-construction. The pre-construction survey reduces well with no issues. The post-construction survey, however, commenced on marks with unknown heights, but did observe marks that were common with the pre-construction survey in which the RL's for these common marks was established. When I combine the 2 sets of data, the RLs are not reduced for the post-construction traverse. How can I successfully adjust the 2 jobs together? I have uploaded the raw .job files, but these contain a lot of junk so have also uploaded cleaned up csv's.
