The ‘Error on Closure’ for measurements on vertical distance to establish bench marks shall not be more than V24K millimetres (where 'K' is the linear distance in Km.). The observations for measurement of vertical distances on bench marks shall be read to accuracy to the nearest 5 mm and for Intersections Points and other points along the pipeline route and at crossings to the nearest 10 mm. The error of disclosure in vertical distance shall be distributed linearly. Azimuth checks shall be made by observations of the sun or Polaris at intervals of 15 - 20 km. These observations of bearings together with deflection angles shall be recorded in survey notes. Azimuth disclosure based on bearings with observed angles at Turning Points shall be equally distributed over the number of stations observed in between. Accuracy of azimuth observations shall be acceptable if the three deductions agree within one minute. The Azimuth carried out should be checked by the BPCL Engineer / Engineer deputed by BPCL.

Chainage Distance should be measured with the help of Total Station / Distomate. However, in case of abrupt slope change the tape / chain may be used. Distance between Intersection Points staked along the pipeline route shall be measured and recorded. In addition, distance between level points shall also be measured and recorded.

Chaining will be continuous in the direction of survey (Flow of the pipeline).The true bearing of all straight portions shall be observed and recorded.

Data on nature of terrain, viz. sandy, stony, vegetation, etc. and type of ground will also be recorded along with changes of change points. Check on distance measurements will be by stadia method at the time of levelling. Standard chain survey format will be used for record keeping.



Measurement of Horizontal Angles

Horizontal angles are measured to indicate the change in direction of alignment and specify the horizontal bend at the Turning Points. The odolite, reading direct to 10 seconds or better, shall preferably be used. Angles shall be measured clockwise from back station to fore-station. Mean of two readings-one on face left and other on face right shall be taken as the horizontal angle. The line at both ends shall be tied to the grid control system being used for end facilities. True bearing at the beginning, end and every 15 - 20 km. shall be observed to keep a check on errors in angular measurements.

Profiles

The continuous profile of the proposed pipeline route shall be established from the reduced levels taken: 1. At the starting point 2. At the Turning Points (TPs) 3. At all intermediate points staked on the ground 4. At all points on the pipeline route where there is a change in slope.

When the terrain is flat, reduced level shall be additionally recorded along the pipeline route which is not to be more than 100 m interval along the center line of the pipeline route and 10 meters across the center line.

When the terrain is undulating observation of reduced level shall be made at a sufficient number of points so as to give an accurate plotting of the ground profile along the route. For road and railway crossings, the reduced levels shall be recorded at all points along the pipeline alignment wherever there is a change in slope within the entire width of the Right-of-way of the road / railway. CONTRACTOR shall prepare a detailed drawing for the crossing in scale 1:100 (in both horizontal and vertical directions) which shall be truly representative of the crossing profile. For river / stream / nalla / crossings, levels shall be taken at intervals of 5m upto 30m beyond the highest banks on both sides. Levels shall be taken at closer intervals, if there is a change in slope. CONTRACTOR shall prepare a detailed drawing for the crossing in scale 1:100 (in both Horizontal and Vertical directions) for the rivers / stream / nalla / crossings of smaller width and 1:1000 for the rivers of bigger width which shall be truly representative of the crossing profile.

For congested areas, closer distance may be adopted, however, location shall be approved by the BPCL Engineer / Agency deputed by BPCL. Parallel Alignment

The pipeline alignment wherever runs parallel to an existing or planned under / over ground facility will be treated as parallel alignment. For underground facilities,



surveyor shall identify and locate them with suitable special ground laths. The following clearances shall be observed in case of parallel alignment defined above.

Between existing / planned electrical power cables / lines and the proposed line – 50.0 Meters. (LT lines), 150 – 200 m for HT lines

Between existing / planned communication cables / line and the proposed line – 7.0 Meters.

Parallel Encroachment

Unless otherwise stated, when the pipeline alignment runs generally parallel to a road or railway it shall be kept sufficiently clear of the Right of Way limits of the facility and any other requirement of the concerned authority may be clearly mentioned.

Azimuth Observations

Azimuth control shall be maintained by observation of azimuth at every twenty kilo meters by closing the traverse on existing control points. Azimuth may be obtained by making observations to sun or star depending upon the location of the area and direction control. In case of azimuth from sun, the computed values must be within one minute. In case of stars the computed values should agree within 10 to 15 sec. Horizontal disclosure between two azimuth stations shall be equally distributed among TPs in between. Survey Notes, Observations & Computations The procedures followed both for field and office calculations shall be such that the results obtained shall be readily understood and retraceable. All up-to-date notes and observations related to the basis for determination of boundary lines and corners shall be maintained by surveyor.

Survey records must contain schematic diagrams of all horizontal controls pertinent to the project showing all existing and established control points, bench marks, any triangulation station and boundary lines.

4. Unconfined Compressive Strength These tests shall be done as per IS-2720 (Part- X) on selected soil sample.

5. Triaxial Tests These tests shall be done on specimens saturated by the applicable of back pressure. Only if the water table is at sufficient depth so that chances of it’s rising to the base of the footing are meager or nil, the tri axial tests shall be performed on specimens at natural moisture content. The magnitude of the back pressure applied shall be indicated in the report. All the stress strain diagrams as well as Mohr circle envelopes shall be included in the report. Density and water content of the sample tested and modulus of elasticity along with shear strength parameters shall be reported.



In case the soils are predominantly sandy in nature and sampling is not possible for tri-axial shear tests, box shear tests shall be carried out as per the relevant IS code.

6. Modulus of Elasticity E-value shall be determined from the tri axial tests. Relative corrections applied to the computed 'E' shall be clearly illustrated in the report.

7. Chemical Tests Chemical tests shall be conducted on soil and water samples as per relevant BIS (latest revision) to report the following: d) pH e) Chlorides in ppm & percentage f) Sulphates in ppm, percentage & expressed as SO3 & SO4.

8. Free Swell Index & Swelling Pressure Test

Wherever applicable, these tests shall be conducted on the selected soil samples collected from boreholes / trial pits from different depths, as per relevant IS codes (latest edition).

9. CBR Test Laboratory CBR tests shall be carried out under both soaked and unsoaked conditions on soil samples (to be collected by the contractor from borrow pit area or as per instruction of Engineer-in-charge) compacted to OMC (Optimum moisture Content). This test shall be carried out as per IS 2720 Part XIV. The Soil samples for the test shall be compacted to the maximum density at optimum moisture content determined in accordance with 2720 Part VIII. Report Detailed report(s) shall be prepared and submitted to BPCL as soon as the field and laboratory works are completed. The report shall include but not limited to following: A location plan showing all the test locations with respect to reference chainage

and spot levels / contour details of the proposed area. General geological information of the site. Character and genesis of soil. Procedure of investigation and method of various testing adopted.



Detailed bore logs indicating co-ordinates, reduced level, ground water table etc., subsoil section along various profiles indicating boreholes nos. depth wise in situ tests like SPT.

All field and laboratory test results shall be plotted against depth and also in tabular form.

Summary of results obtained from various tests and their interpretation to evaluate various soil parameters.

Ultimate and safe bearing capacity from shear as well as from settlement criteria

(i.e. for 25 mm & 40 mm) for the shallow footings of size ranging from 1 m to 4 m and for rafts of size greater 6.0 m placed at different depths from 1 to 3 meters. The recommendation shall also contain provision of basement raft and its construction aspects. The recommended bearing capacities shall be worked out based on various field and laboratory tests.

Recommendations of CBR value etc regarding design and construction of roads

and other paved structures and also suitability of soil for back filling in foundations.

All recommendations shall be supported by back up calculations.
