Archive context
“yo survey, design and construction suru gareko 30 barsa bhanda paila ho, tesaile section wise coordinate chainna jaha samma lagchha hai ani head office storema paani pasera dherai documentharu dubayera/ vijera bigreako pani thiyo”

English translation “The survey, design, and construction began more than 30 years ago. As far as I know, section-wise coordinates may not be available, and many documents in the head-office store were submerged or damaged when water entered.”

This explains why local geometry survives without enough coordinates for precise map placement.

Additional access-tunnel note At 120 m from the access-tunnel face: bottom 1390.67 m and top 1396.25 m. The source presents this as a distance from the face, not as a surveyed chainage such as Ch. 0+120.

These values do not provide Easting, Northing, bearing, a datum statement, or a longitudinal slope at each chainage. View the supplied handwritten note.
