OD16983/2026-2027:Providing and fixing RCC pillars at every 250 m interval along the road, of size 150mmx150mm, 450mm long, 250mm above ground level and 200mm below GL. casted in M20 Grade concrete reinforced with 4 nos of 8mm dia longitudinal bars and 6mm dia stirrups @ 150mm c/c, firmly fixed in position by means of foundation of size 0.3mx0.3mx0.15m in M15 grade concrete below ground level including painting 2 coats on exposed surface with synthetic enamel paint

OD16985/2026-2027:To carry out DGPS Survey to establish primary control points- it includes observation of road data by using dual constellation GNSS receiver, processing,network,adjustments and submission of data in WGS 84 datum and UTM/TM projection system including traverse report (one intervisible pair per 5km).

OD16987/2026-2027:To carry out Traverse to establish horizontal control stations on the proposed road stretch running through from one DGPS stations at every 2.5km using eletronic total station instrument at maximum of 250m intervel with an accuracy of 1 in 20000 which includes submission of hard and soft copies as per IRC standards.

OD16986/2026-2027:Fly levelling to shift levels from given bench mark value to next bench mark station to horizontal traverse stations and availablr permanent structures all along the road for the elevation purpose by closed circuit which includes submission of hard and soft copies as per IRC standards.

56.13:Providing access to the site clearing site and making good for surveying in order to provide clear line of site devoid of any hindrance due to vegetation etc. and clearing areas for station points (This item is applicable only for sites without access such as in case of new road formation, bridge and building sites at in accessible locations).

56.12.a:Total station surveying and preparation of site plan - Plain and open area without hindrance to line of sight with 1 m contour intervals , with 5m x 5m interval.
