ABSTRACT: Geo-environmental intrusive investigations are often challenged by limited or restricted access to some portions of the study area. Existing infrastructure must be identified and protected and isolated before work can proceed. Depending on the scope of the study and the complexity of the existing infrastructure, it may be necessary to seek permits, access agreements or negotiate licenses of occupation to gain access; these activities can add significant time and costs to an investigation. Additional safety measures needed to protect the infrastructure, the workers and the public. It may not be possible to obtain access from the property owner. This paper will discuss the value of completing an historical review that includes the existing infrastructure design and construction details, in advance of undertaking an intrusive investigation. Two case studies are discussed, both demonstrating the value added by the historical review, and challenges encountered searching for and interpreting historical records.

RÉSUMÉ: Les études géo-environnementales sur le terrain se compliquent souvent par un accès limité ou restreint à certaines parties de la zone d'étude. L'infrastructure existante doit être identifiée et protégée ou isolée avant que le travail puisse commencer. Selon la portée de l'étude et la complexité de l'infrastructure existantajouter beaucoup de temps et de coûts à une étude. Des mesures de sécurité supplémentaires sont nécessaires pour protéger l'infrastructure, les travailleurs et le public. Il peut ne pas être possible d'obtenir l'accès au site de la part du propriétaire. onception et construction démontrant à la fois la valeur ajoutée de l'analyse historique et les défis rencontrés lors de la recherche et de l'interprétation de documents historiques.
