scope:

This Standard addresses and supports spatial planning issues of

Normal operations

Degraded operations during temporary works and special events

Controlled evacuation

Evacuation in the event of a fire

This applies to the spatial aspects of station planning in the following areas

Passenger flow

Ticket hall

Access and Interchange facilities

Secondary income facilities

Operational staff accommodation

Station Operations Rooms and Control Facilities

Ticket issuing facilities

Platforms

Lifts and Escalators

Evacuation

Public facilities

insofar as they relate to Station planning

Purpose

The purpose of this Standard is to define the space requirements for public areas and staff accommodation in stations

This Standard applies to

New stations

New assets within existing stations

Altered assets within existing stations

When work is proposed that

does not involve alterations to the primary structure of the station, and

is defined as clause 1.2 b) or c) (new or altered assets within existing stations) and

where it is impossible to comply with the headroom, platform width and room size requirements of this Standard without major re-building/alteration to the existing structure of the station, then the following conditions apply

Risks that are introduced by the proposal shall be identified, assessed and evidenced ALARP by the proposer

Proposals shall be demonstrably optimal in relation to the compliant state for new stations

Proposals shall always comply with the minimum dimensions set out in sections 3.5.2, 3.9.5.3, 3.10.2.4, 3.10.7.2, and 3.12.9.1 of this Standard, each of which should be read in full to achieve an acceptable condition

The reason for these sections is to recognise that the structure of an existing station may not be able to accommodate some of the constraints of this Standard in terms of linear dimensions, available floor area or volume. If this is the case the onus is on the Supplier (as proposer) or other proposer to identify all risks associated with their proposal and to prove and evidence that these are ALARP in accordance with other relevant category 1 Standards

The Supplier (as proposer) or other proposer must also be able to demonstrate that their proposal is the best that can be achieved under the circumstances, offering optimal compliance to the Standard whilst meeting the requirements of LU category 1 Standard S1538 'Assurance'. This will typically mean an analysis of available options. If these conditions are satisfied and if the minimum dimensions listed in the relevant sections of this Standard can also be met then a concession application is not required

All dimensional requirements for passageways, stairways, and run-offs are not affected by the clauses in this section, which shall always be fully compliant. Proposers shall seek additional support from the technical content manager of this Standard (see Responsibilities section clause 4.3) if compliance cannot be achieved and a concession is likely to be required

For temporary works in place for not more than six months and where it is impossible to comply with the spatial requirements in this Standard as a consequence of installing the Temporary Works e.g. Headroom, platform width, room size, run-offs, then the following conditions apply

Risks that are introduced by the proposal shall be identified, assessed and evidenced ALARP by the proposer to LU, and

Proposals shall be demonstrably optimal in relation to the compliant state
