Hi, David
While you do not give any information regarding the nature and age of the private school building(s), or the porpose of the survey, we deal with usch reports on a bespoke basis.
Most houses and flats are regular grists to the mill and it is arguable that survey reports could be somewhat generic, hence various attempts to produce templates. Other buildings, such as schools (privare or otherwise) are often unique and need the surveyor to rely on his/her training and experience.
