Item Breakup - A-NS Items for Pre & Post Tamping Track Measurement Survey using Gedo Vorsys Trolley system

Pre Tamping Measurements (a)EstabIishments of main GNSS ( DGPS Kilometre Base) Point & refrence point establishment at 150 Pleter maximum interval along the track."

"(b)Pre measurement for tamping with total station & prism Gedo Kilometre trolley measure and store Gauge. Cross elevation, Chainage , shift and lift value at every 3m i.e Every 5th sleeper interval along the track centre line and coordinates of track centre line at every 3m to be submitted with track geometry (per/km/Round)"

"(c )Construct Target/ Designs alignment with the good points of Kilometre existing pre measurment profile in desing software. To export data in ALC format with design alignment of measured reading in M/C and to provide track adjustment file with Ver. extension and also to provide Geo Geometry file to provide text file with slew, uplift and gauge at every 3m i.e every 5th sleeper interval for tamping machine operator during reference."

"Post Tamping Measurements (a)Post Tamping Measurements with Kilometre total station & prism Gedo trolley measure and store Gauge. Cross elevation, Chainage , shift and lift value at every 3m i.e Every 5th sleeper interval along the track centre line and coordinates of track centre line at every 3m to be submitted with track geometry (per/km/Round)"""

Reporting (a)Report & plotting soft and hard copies of slew & uplift Kilometre report at every 3m/ 5m i.e every 5th sleeper interval compared with design Vs pre profile report of offset distance from track entre to OHE, neighbouring track centre & platfrom point." Total 8207725.54
