The purpose of this standard is to contemplate the different levels of layout of the works, that is, the primary network on the site, the implementation of layout bases, their transfer to other levels, the location of position points and leveling procedures for these operations. This standard gives values for permissible deviations when measuring and restating and recommends the use of certain methods and instruments. Likewise, guidance is given on how to control lack of precision in the staking process.
