KIIFB-Improvement of Venniyoor (Pookkiparambu) -Pathinarungal Bypass Road (Thirurangadi LAC)-Additional topo-survey and mandatory Investigations for Revised Alignment-Investigation Work

OD13222/2026-2027:Detailed topographic survey using Total station/mobile Lidar and preparation of site 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 mentioned in the scope of the in plain terrain work within the limit of survey). The survey shall be include establishing DGPS Control points at starting and ending of the project in pairs and at 4Km intervals (in pairs) in plain and rolling terrain and 2.5Km intervals ( in pairs) in hilly terrains. It shall also include establishing inter visible traverse control points note more than 250m apart with accuracy at least 1:10000 and desirable 1:20000 in distance measurement. Elevations on each of the control points connected to MSL of GTS Bench marks. Using precision levelling. Separate bench marks need not be established. Including Taking sufficient Color copy prints (5nos)
