The calculations contained in this document were developed by the ''Mining Group of the Design & Engineering Organization'' and are intended solely for the use of the ''Design & Engineering Organization'' in its work regarding the subsurface repository. Yucca Mountain Project personnel from the ''Mining Group'' should be consulted before use of the calculations for purposes other than those stated herein or use by individuals other than authorized personnel in the ''Design & Engineering Organization''. The purpose of this calculation is to provide design inputs that can be used to develop an as-built drawing of the Exploratory Studies Facility (ESF) for the planning and development of the subsurface repository. This document includes subsurface as-built surveys, recommendation to complete as-built surveys, and Management and Operating Contractor (M&O) Subsurface Design Drawings as inputs. This calculation is used to provide data and information for an as-built ESF subsurface drawing and is not used in the development of results or conclusions, therefore all inputs are considered as indirect.
