6.1 General Survey co-ordinates and maps shall use standard UK horizontal and vertical datums as origin with survey observations tied into Government survey control stations and benchmarks as necessary.

The scale of capture of survey data shall be suitable to support mapping at 1:2500 scale or better

where larger scale mapping is used for crossings and other specialist areas.

6.2 Co-Ordinate System Parameters Contractor shall perform the topographic surveys using the following co-ordinate system parameters:

Spheroid Airy 1830

Semi-Major axis (a) 6377563.396m

6.3 Survey Control Accuracy Survey of control monuments shall be conducted to achieve accuracy as follows:

Primary 1/10,000 Secondary 1/5,000

Surveying of the pipeline alignment from secondary control, using RTK GPS or Total Station techniques shall be conducted to achieve:

Horizontal accuracy ± 0.05m

Vertical accuracy ± 0.05m Surveying of stations and valve sites shall be conducted to achieve an accuracy of ± 0.01m

relative to the site survey monuments.

To ensure these accuracies are maintained, the CONTRACTOR shall make regular (not longer than manufacturer’s recommended frequency) verifications to demonstrate that the initial bench calibration by the manufacturer is still valid and within specified requirements.

6.4 Geodetic Horizontal and Vertical Datums All survey work shall be based on OSGB36 datum, Airy 1830 Ellipsoid and Transverse Mercator co -

ordinates or otherwise as directed by the COMPANY.

Topographical heights shall be in metres and based on Ordnance Datum Newlyn mean sea level (MSL) as defined by UK maps.

6.5 Survey Control Horizontal and vertical control of the work shall be undertaken utilising dual frequency geodetic receivers or Total Station equipment with levels derived using precise automatic survey levels.






The control shall be referenced to a minimum of 3 geodetic reference stations co-ordinated with

respect to the Ordnance Survey national grid at 1st or 2nd order level. Levels shall be derived from bench marks of a similar accuracy.

Markers, reference points and monuments for the survey may vary in composition from Hilti or road

nails in concrete, to steel pins to concrete monuments. Material for monumentation shall be chosen in regard to the terrain and situation that exists at the site of the survey and be approved by COMPANY. The primary network of survey monuments shall be constructed using markers that will

remain in serviceable condition for up to 3 years.

The location of the monuments shall be chosen to offer both convenience to the project and protection for the monument. Base line monuments will be used to establish the location of the

centre-line of the entire project. Benchmarks for elevation control shall be located on the most permanent and stable base convenient to the site. Horizontal and vertical control monuments shall be placed at intervals of not more than 500m or as directed by the COMPANY.

6.6 Survey Control Measurements The CONTRACTOR shall carry out the WORK using modern GPS systems combined, where necessary (e.g. where GPS signal masking occurs), with Total Station and precise level technology.

GPS control survey shall be carried out using a minimum of two dual frequency receivers. Final

locations shall be computed using post-processed static techniques with a minimum of two vectors being used to co-ordinate any new survey station. Equipment, data collection process, compilation and reporting format shall be subject to the approval of COMPANY prior to implementation. Each

surveyor shall be responsible for locating the designated data and collecting data for subsequent RTK post-processing.

6.7 Primary Control A primary control network of survey stations is required that extends to the geographic limits of this project.

The CONTRACTOR shall tie-in to a sufficient number of primary geodetic control points required to meet positioning tolerances and ensure consistency within the geodetic network. The CONTRACTOR shall devise the appropriate network plan, and shall utilise existing national survey

stations. Values for existing national control stations shall be obtained by the CONTRACTOR. At least three horizontal and three vertical geodetic control point ties shall be made to first or second order national survey stations from primary control stations.

Sufficient baselines shall be independently measured to ensure that all new control stations are established as an over-determined solution.

The CONTRACTOR shall liaise with COMPANY as to existing monuments that may be available.

All existing local horizontal and vertical control station descriptions shall be included in the final report. Station markers shall be made clearly visible and able to be located by any third party using the station description sheet.

6.8 Secondary Control Secondary network stations shall be established as required to complete the field survey work.

Such stations shall be tied into the primary network and full station descriptions (including witness marks) provided to the COMPANY.






6.9 Calibration and Check Survey The accuracy of primary and secondary control shall be determined by the CONTRACTOR to meet

the requirements of the topographic survey.

The CONTRACTOR shall:

Keep GPS, electronic and optical surveying instruments in close adjustment according to

manufacturer’s specifications or in compliance to textbook standards. Ensure that electronic distance measuring devices are compared to a base line, measured by

static GPS or a standardized or calibrated tape, at least every six months. Field

measurements of angles and distance shall be done in such fashion as to satisfy the closures and tolerances expressed above.

6.10 Level Control Local vertical control shall be undertaken using double measurement techniques (forward and reverse) using control data obtained from the national mapping authority. A minimum of 2 vertical

control points shall be used at the terminations of the routes and two further points along the route section.
