STC25 Manhole Chamber Surveys Sheets provide a very useful summary report of specific manhole inspection chambers for designers and engineers alike. When conducted conventionally, the accuracy of reports will always rely upon the competence of the surveyor and Infotec have always prided themselves upon producing high quality, reliable information upon which their clients can rely. However, the application of new technology and remote survey techniques has enhanced the way in which manhole sheets can now be produced, whilst ensuring consistency, comprehensive data capture and most importantly improved health & safety by removing or significantly reducing the need for confined space entry.
