The standard specifies all surveying activities for which a co-ordinated (in relation to a survey grid) Topographic, Engineering, Land, or Measured Building survey is required. This standard is applicable to individual project scopes during the life-cycle of a renewal or project.

It specifically excludes ground investigation, geotechnical, building condition, dilapidation surveys and surveys associated with Network Rail owned and operated measurement trains.

It is for the use of Project Managers, Designated Project Engineers (DPE) or project teams, in consultation with a geospatial engineer (Client’s Survey Manager)...

The standard also explains how an appropriate topographic survey forms the basis of BIM by reference to the Survey4BIM Digital plan of works and the various parts of PAS 1192 Parts 2 to 5.

This is the main document that provides a strategy and general introduction, establishing some basic principles to be applied across all disciplines. Other documents covering the main disciplines, in the previous suite of standards, are now included as modules.

This standard is intended to be used with the Module documents associated with the discipline and related to the type of survey required.

NOTE For example, where a track survey and then a design for S&C renewal is needed, this standard and Module 1 would be consulted to understand what is required. A project survey strategy would be defined as specified in this standard and the detailed specification would be derived from Module 1.

Purpose

The standard sets out requirements for the project manager and engineer to specify topographic survey work, by identifying key stages to deliver good quality work for current and future needs. This lowers the risks associated with poor survey work for projects. “Survey once and use many times” also provides better value for the money spent.
