Amount

Detailed topographic survey using Total station/mobile Lider and preperation of site plan with Strip Plan of minimum of 15m on either side of the centre line and taking cross section details at 25m intervals on straight roads and 10m interval on curves ( survey includes details of all features as mention in the scope of the in plane terrain work within the limit of the survery). The survey shall be include establishing DGPS control points at starting and ending of the project in pairs and at 4 KM intervels (in pairs) in plane and rolling terrain and 2.5 Km intervels (in pairs) in hilly terrains.IT shall also include establishing inter visible traverse control points not more than 250m apart with accuracy of at least 1:10000 and desirable 1:20000 in distancemeasurement. Elevation of each other control points connected to MSL of GPS Bench Mark using precision levelling with 1meter contour intervals. Seperate bench marks need not be established. Including taking sufficient colour copy prints.(5 Nos)

Establishing DGPS control points onTOR steel bar of 10 mm dia fixed in RCC pillar of size 20X20X70cm embeddded in concrete M15 up to a depth of 40 cm and the balancce 30 cm above the ground shall be painted yellow

Establishing traverse control points with elevations on pillar of size 5cmX15cmX60cm M20 grade RCC pillar with a nail fixed on the top surface. The pillars shall be embedded in the concrete.Spacing 250 M apart as a bench mark - control pillar. The spacing shall be maximum 250 m apart and intervisible. No seperate bench mark need to be established
