  Too much time to switch numbers when you can auto number the next available point number . I don't separate the numbers and use coding on big projects to do line work or to control contours.

  For small projects, we don't keep track of number ranges much. But for larger construction projects, we group our numbers so we can keep consistency when we have several people calculating points.

  Typically it will be points 1-499 for control and check shots, 500-999 for building structures and then we break out (usually anyway) each utility with different number groups.

    I guess for the sake of clarity, we keep track of number ranges on our construction projects for pre-calculated points only.

    For data collection of non-construction work, we try to keep 1-500 open for control and check shots. The rest is open season on numbering.

   In our company we use

   

  The real numer for the  Active or Passive national geodetic network' points

  under 100 for control points

  above 1000 for everything esle but we id  by  codes

  In the past, when using the old 48's, I would leave control under 100. This was so that you can open a daily file and use the main file for control as a control file that couldn't be messed with by accidentally changing or deleting something. You could use that as long as the points never got over 100. Nowadays, I don't think too many people are using 48's for data collection anymore so its not an issue.
  
  For construction, I had a surveyor use point groups for sanitary, water, drainage, roads, etc. Each category would get a range of about 100 depending on the size of the project.
  
  The surveyor I work for right now uses the 500-599 range for state plane coordinates he has due to his filing method with AutoCAD. He has folders on an external hard drive for jobs and categorizes them in what Section-Township-Range they are and each will use the same database for all work done in that section. This saves him from having to break down a section multiple times if he has done work in there previously. All you have to do is run out and "tag" 2 points he has coordinates on and he can then calculate the entire section from there, rotating your new points in.
