NR NR/L3/CIV/0063 ISSUE 2 PDF

This standard applies to all piling, drilling, crane, MEWP, SPMT and similar temporary works operations to be undertaken on, or adjacent to, Network Rail Managed Infrastructure, including that which has been designated a High Street Environment, where applicable. 

The standard applies to piling, drilling, crane, MEWP, SPMT and similar temporary works operations where the safety of the operational railway might be affected as a consequence of:

a) Plant operator or workforce error;

b) The failure of the ground/working platform/mats supporting the piling rig, crane or other supported equipment;

c) Equipment or accessory failure;

d) Inadequate interaction with the existing ground (including vibration, displacement and loosening affects);

e) Failure within compound collapse radius of the attendant crane(s) and load(s). 

f) Failure when in service or out of service, 

g) Failure during erection or deconstruction or during movement, 

h) Failure during inclement weather. 

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 e.g. use of On Track Plant (OTP). 

This standard is complementary to, and should be read with, the following standards: 

a) NR/L2/RMVP/0200 Infrastructure plant manual, including (but not limited to) Module P513 - Mobile plant (non-rail mounted) and road vehicles, Module P503 lifting operations and Module P508 MEWPs; 

b) M&EE standard COP0011 code of practice for planning and executing lifting operations; 

c) M&EE standard COP0032 code of practice for plant any line open (ALO) working. 

This standard is applicable to all projects where, in the event of mishandling or failure, any part of the equipment in use, and not in use (i.e. out of service), or its load, might collapse within a line drawn 4 metres (4m) to the outside 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. See Figure 1 on page 12. 

It applies to designers and executers of works, of both Network Rail and Outside Party / Third Party constructors/developers. 

NOTE 1: The intention is for these parties 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 On Track Plant, Jack-Up-Barges, pontoons or cranes on waterways. In such cases specialist advice will need to be sought. 

NOTE 2: NR/L3/OHS/005, Work Instruction; Design and Construction Management in a High Street Environment, is for projects where there is no effect on NRMI. Standard NR/L3/CIV/0063 will apply, unless those persons determining whether a project comes within the scope of NR/L3/OHS/005 confirm in writing that there are no risks to NRMI.

Purpose 

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

NOTE 1: *Similar temporary works operations might include, amongst other things, construction hoists, transport platforms, mast climbing work platforms, telehandlers, rotating telehandlers , excavators undertaking suspended load lifting operations, lorry loaders, and mobile concrete pumps with placing booms. 

NOTE 2; **See definition for “adjacent to” in clause 4. 

This standard supports a safe system of work, relating to the piling, drilling, crane, MEWP, SPMT and similar temporary works 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 operations on, or adjacent to, NRMI 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 requirements to be applied whenever piling, drilling, crane, MEWP, SPMT or similar temporary works operations are to be carried out on, or adjacent to, NRMI where, in the event of mishandling or failure, any part of the equipment in use or its load might collapse within 4m of the boundary to NRMI. 

Measures include, but are not limited to, accounting for: 

a) hierarchy of risk, 

b) appropriate design check category, 

c) appropriate under-utilisation of capacity, 

d) appropriate measures for uprating loads, 

e) appropriate measures to prevent slewing, 

f) provision of tagging or similar measures, 

g) appropriate measures for the provision of adequate working platforms, to support all plant and equipment covered by this standard.
