These Special Conditions are needed to make sure that all works by Outside Parties on or near the railway are done in a way which has been agreed with LU. This shall ensure that, as far as is possible, the risks of damage to the railway and injury to those using or operating it, the general public or those undertaking the works are understood and mitigated.

The term LU Engineer is used in the context of these Special Conditions to define the member of staff appointed by LU to manage the interface between LU and the Outside Party on a particular Outside Party project. The LU Engineer may require support and assistance from site inspectors or other specialists within LU (collectively referred to as the LU Representative in this document).

These Special Conditions are complimentary to, but do not supersede, the specific requirements in any development agreement, lease, covenant or other legal agreement that contains protective provisions in favour of LU or their predecessors. The LU Engineer noted in 2.2 above may not be the Engineer as defined in any legal agreement (and specifically appointed as Engineer under LU company standing orders) and should not be construed as such. To minimise confusion, the Engineer defined in any agreement will notify the Outside Party of the contact details of the LU Engineer together with their roles and responsibilities. The Outside Party must refer any required clarification on the split of engineering responsibilities to the Engineer.

These Special Conditions shall be:

ADVISORY for Outside Parties working on their own land (leased or freehold) and not entering LU Land (defined as 'any land, including airspace, subsoil, property, building or structure in the freehold or leasehold ownership or in the occupation of LU, excluding land owned by LU or Transport for London leased to an Outside Party'). However, if these Special Conditions are not followed, the Outside Party may have difficulty demonstrating adoption of "best practice" in the event of an incident.

MANDATORY for works requiring temporary use of LU Land or airspace for Outside Party maintenance or new works that do not modify, remove or add to LU assets (known as New or Altered Assets).

COMPLEMENTARY but subservient to LU assurance procedures and design standards for any Outside Party works including LU New or Altered Assets. It shall be at the sole discretion of the LU Engineer (in consultation with the Head of Infrastructure Protection, LU Strategy or other interested LU parties) whether a project includes New or Altered Assets. In any case works including New or Altered Assets will be subject to some form of licence or other legal agreement with LU. Where an Outside Party wishes to undertake work on property owned by LU then that work shall be done to the same standards and methods of work undertaken by LU and by staff qualified to the same degree of competency. In addition the Outside Party shall have to give an indemnity to LU and shall require a licence or other agreement with LU to undertake the work.

Some or all of the provisions in these Special Conditions will be relevant to the particular works being proposed by the Outside Party and the associated sections of this document should be used accordingly.


Infrastructure Protection - Special Conditions for Outside Parties working on or near the railway, supports London Underground (LU) Standard S1023 “Infrastructure Protection”.

This document assists Outside Parties (defined as 'any person, firm, or body; other than LU or a person, firm or body employed by LU') in identifying the risks associated with working on or near the railway and identifies ways of mitigating those risks. They shall be issued by LU to any Outside Party working on or near the railway.
