NR NR/L3/CIV/0063 ISSUE 1 PDF

This standard applies to all piling, drilling, crane, MEWP and SPMT works to be undertaken adjacent to the Network Rail

Managed Infrastructure, including those which have been designated a High Street Environment, where applicable.

The standard applies to piling, drilling, crane. MEWPs and SPMT operations where the safety of the operational railway may be affected as a consequence of:

•    Plant operator or workforce error;

•    The failure of the ground/working platform supporting the piling, crane or other support equipment;

•    Equipment or accessory failure;

•    The piling, drilling, crane, MEWP or SPMT system and its interaction with the existing ground (including vibration, displacement and loosening affects);

•    Compound collapse radius of the attendant crane(s) and load(s).

This standard covers the safe installation and removal of piles and working platforms but not the effect of piles and working platforms on the infrastructure.

This standard does not cover on or near the line operations.

NOTE 1:  Refer to standard NR/L2/RMVP/0200 Infrastructure plant manual including Module P513 - Mobile plant (non-rail mounted) and road vehicles.

This standard is applicable to all projects where, in the event of mishandling or failure, any part of the equipment in use, or its load, may fall within 4m of the boundary to Network Rail Managed Infrastructure, notwithstanding whether the works are for the railway infrastructure itself or for structures / developments adjacent to the railway.

It applies to designers and operational teams, of both Network Rail and outside party constructors/developers.

NOTE 2: to understand at an early stage the constraints imposed on the design solution selected.

This standard does not cover signal sighting, radio signals and Overhead Line Equipment (OLE) implications, nor specialist equipment such as Jack-Up-Barges, pontoons or cranes on waterways. In such cases specialist advise will be sought.

NOTE 3: NR/L3/OHS/005, Work Instruction; Design and Construction Management in a High Street Environment, is for projects where there is no effect on Network Rail Managed Infrastructure (NRMI). Standard NR/L3/CIV/0063 shall apply unless those persons determining whether a project comes within the scope of NR/L3/OHS/005 confirm that there are no risks to NRMI.

Purpose

This standard addresses risks where piling, drilling, crane, mobile elevated working platform (MEWP) and self-propelled modular transport (SPMT) operations are taking place on or adjacent to Network Rail Managed Infrastructure.

This standard supports a safe system of work, relating to the piling, drilling, crane, MEWP and SPMT operations, that maintains the safety of the railway so far as is reasonably  practicable, in conjunction with other standards.

This standard outlines modern methods and procedures in order that the risk of undertaking piling operations adjacent to an operational railway can be minimised to the extent that works may be progressed as far as practicable without resorting to possessions and electrical isolation.

This standard sets the minimum standards and processes to be applied whenever piling, drilling, MEWP, SPMT or crane operations are to be carried out on or adjacent to Network Rail Managed Infrastructure where, in the event of mishandling or failure, any part of the equipment in use or its load may fall within 4m of the boundary to Network Rail Managed Infrastructure.

NOTE: The distance of 4m has been chosen to align with CPA guidance previously agreed with NR in current guidance and offers an agreed margin of safety.

Measures include accounting for the appropriate design check category, appropriate de-rating, appropriate measures to prevent slewing, provision of tagging and appropriate measures for the provision of adequate working platforms, to support all plant and equipment covered by this standard.
