Conducting Slope Stability analysis along with aerial survey of deep cuttings and slopes of major bridge locations, land slide areas, Design/Suggestion for stable slopes and submission of scheme for remedial measures to protect deep cutting, Design of RCC retaining wall on open and deep foundation, subsurface drainage, covered drains etc. on vulnerable locations under the jurisdiction of ADEN/RAIR of Sambalpur Division.

A-Execution of Non-SOR Items for Conducting Slope Stability

Carrying out slope stability analysis by finite element method & numerical analysis at deep cutting & high embankment showing creep, slip and design of instability The report of analysis 1 should be submitted in three copies in soft & hard copy. The rate shall include cost of labour, equipment etc. Note-1: Each location will be of up to 100m stretch. Note-2: Transportation of men and material to the site will be arranged by Railway on train or Trolly on production of the indemnity bond for location where there is no road approaches, for the purpose of execution of work, at the convenience of Railway. Contractor will have no claim in case transportation to site could not be arrange at particular time by the Railway. Note-3 : The unit 'each' means 'each location' Above/

Working out a detailed scheme for Slope protection, Slope stabilisation and recommending for providing remedial measure i.e. slope correction/retaining wall/ geogrid/ turf, subsurface drainage,covered drains etc., Drain and River training and other protection works required based on field and laboratory investigation report and backed by design calculation, drawing, technical write up including providing BOQ ,Budgetory costing and technical specification of proposed stabilisation measures/Scheme and submission to Engineer in charge in the form of draft report for acceptance, followed by submission of final report in requisite copies after incorporation of any observations given by Railway. Note: Each location will be of up to 100m stretch. Above/

Geological Investigation: Geological mapping at deep cutting,deep filling location as 3 per requirement of Railways for a corridor width upto 200 m (100 m on either side) in scale 1:5000 of critical area and submission of geological Map of relevant areas and cross section (1:5000H & 1:500V) across the valley/nullah/streams/cut slope and across other important geological features including survey work required (by total Station and DGPS) for geological mapping. The report should be submitted in 3 copies. Above/

Geological Mapping Carrying out detailed aerial survey and aerial photography using UAV for the area as shown by Railways. Processing of the data and production 3-D image, generation of point cloud data and submission in the form of 3-D image and point data x,y,z co-ordinates for use in cad software generation of cross sections at every 30 m and contour plan of the surveyed area. Above/
