2. REQUIREMENTS

2.1 All survey works shall be performed under the supervision of a experienced persons deputedby the CONTRACTOR.

2.2 All measurements shall be in metric units.

2.3 The reading and noting shall be neat, legible and scorings and over-writing shall be dulyinitialled by the Contractor.

2.4 All surveys shall be carried out using approved methodology and equipment e.g. GPS,DGPS, Total Stations, Auto levels,High Precision Theodolite, EDM.

2.5 Contractor should check for the presence of underground services prior to commencing ofany drilling or trial excavation and will validate and confirm that no underground services areat risk to be damaged or disturbed in any way.

3. PRELIMINARY AND LOCATION SURVEYS

The Contractor is expected to make himself aware of the general conditions of the terrainbefore starting detailed survey.

3.1 Alignment and location surveys

A preliminary survey for locating the centre-line of pipeline alignment on the ground shall becarried out as follows:

3.1.1 Contractor shall make a preliminary survey along the route of the Proposed Pipe line toestablish flag control point. Based on the preliminary survey drawings, a geocoded mappingbe developed as preliminary plan, particularly the start and end point and other majorTP’s/IP’s. Contractor shall study and suggest better alignment based on site visit and shallmake suitable alteration in the proposed route after consultaton with OWNER/OWNER’SREPRESENTATIVE.

3.1.2 Where it becomes apparent that a better route could be followed, the Contractor shallconsult the OWNER/OWNER’S REPRESENTATIVE for authorisation to make a change. Inselecting the pipeline route, the contractor shall take into account the requirement for safeconstruction, operation and maintenance of pipeline.

3.1.3 Alternate routes ( partly )at different places has to be surveyed considering the requirementfor safe construction, operation and maintenance etc. Routing should take into account anyplanned facilities / utilities not only at the time of survey but also facilities which may comeup in future. This needs to be accomplished by collection of approved Master Plans of thearea along the route.

033


3.1.4 Turning Points (TPs) shall be located by Contractor considering the following:

· Detailed survey would be carried out using Differential Geographical Positoning systemand/or Geographical Positioning system and Total Stations. Use of high precisionTheodolite and/ or Total Station shall be made in suitable conjunction with GPS toestablish the markers.

· To avoid obstruction along the line, by ranging on ground and shifting the TurningPoints, wherever needed.

· Check for terrain gradient by using hand Clinometer/ Total Stations.

· Ensure proper angle of crossing by keeping as nearly right angle (to road/rail/riversetc.) as possible. Unless mentioned otherwise all minor/ major crossings shall besurveyed by total stations.

3.2 Staking of pipeline route

3.2.1 The pipeline defining trench centre line shall be staked by placing suitably painted markerstakes at Turning Points (TPs) and at Intermediate Points (IPs) between consecutive TPs.All Turning Points (TPs) and intermediate points are referred as Intersection Points.

The pipeline centre line shall be staked on the ground as follows:

First, the Turning Points (TPs) shall be staked on the ground. After locating and marking theTPs, the intermediate points shall be staked while measuring stack distance. The stakingshall normally be done at intervals of 500 M along the centre line of the pipeline.

3.2.2 The Intersection Points shall be serially numbered from the starting point. The serial numberof each Intersection Point shall be boldly inscribed on the marker stake. In addition, theTurning Point (TP) marker stake shall identify the Turning Point reference number from thestarting point.

3.2.3 For Intermediate Points (IPs) letter “P” shall precede the serial number of the instersectionpoint marker. For Turning Points, the “TP” shall precede the Turning Point referencenumber.

Example : P52; TP16

3.2.4 The marker stakes at Turning Points (TPs) shall be referred with three reference stakesaround the TP. The reference stakes shall carry the Turning Point reference number andtheir respective distance from the TP marker stake.

Example : TP32 – 3.5L; TP6 – 4.8R, TP18-3.6W etc.

3.2.5 Change in direction of line shall be marked on the TP marker stakes. In addition, directionmarkers near TPs and other locations shall be placed wherever necessary.

3.3 Stakes and Markers
