SYSTEM SAFETY ENGINEERING (RAIL WORKS)
5.1
General
This Clause 5 applies to the design of Railway Infrastructure.
The Contractor must:
(a)
ensure that safety principles are considered throughout the design process so that hazards are identified,
analysed and treated to eliminate or minimise risks SFAIRP;
(b)
ensure its design procedures have due regard for the requirements of the documents listed in Clause 1
“General” and, where appropriate, comply with any guideline established by the Rail Commissioner;
(c)
adopt a suitable model for safety engineering that is proven and accepted in the Rail industry, such as the
guidance provided by Engineering Safety Management - UK Yellow Book Edition 3 (Yellow Book) or EN
50126, EN 50128 and EN 50129;
(d)
ensure the Risk Management Plan includes the identification, analysis, evaluation and treatment of safety
risks, that relate to the construction, operation and maintenance of the Works;
(e)
prepare all records and other documentation required to enable the Commissioner to obtain accreditation
from the National Rail Safety Regulator for the Works; and
(f)
have a documented Safety in Design procedure which outlines the Contractor’s process for managing
design implications in demolition, construction, operations and maintenance of the Works through each
design stage.
(g)
have a clearly defined process to accept residual Hazards (including supporting documentation) from works
undertaken by the Principal including Third Party Services relocation and include those items in their
approach to System Integration and Rail Safety Justification.

Contractor’s System Safety Engineering Activities
5.2
The process to identify, analyse, evaluate and treat hazards must be documented in the Contractor’s Risk
Management Plan and / or Contractor’s Engineering and Design Management Plan (CEDMP). These must:
(a)
document hazards associated with the delivery of the Works and establish a hazard registers;
(b)
include the analysis of hazards and determine how hazards are to be mitigated SFAIRP;
(c)
include reviews of designs and hazard registers to determine the suitability of mitigation strategies
implemented through design;
(d)
generate records of all safety engineering activities, including a safety engineering report for each design
stage demonstrating the implementation of safety engineering activities; and
(e)
include reviews of safety engineering planning, implementation and records by a competent reviewer at key
milestones during the project.
(f)
outline approach to the use of:
i)
Preliminary Hazard Analysis;
ii) HAZOPs;
iii) FMEA; and
iv) Human Factors Analysis.
5.3
Accreditation with the National Rail Safety Regulator
The Contractor must prepare a Rail Safety Justification (Safety Assurance Argument) which demonstrates that the
hazards introduced by the work under the Contract have been mitigated SFAIRP and is suitable for submission to the
National Rail Safety Regulator to obtain accreditation for the Works.
The Contractor must provide reasonable assistance and cooperation with the Commissioner’s personnel regarding
the preparation of a submission for accreditation from the National Rail Safety Regulator.
The Rail Safety Justification must include relevant information necessary to satisfy the National Rail Safety
Regulator in regard to:
(a)
definition of the systems delivered or modified as part of the Works;
(b)
change impact assessment;
(c)
safety;
(d)
quality;
(e)
commissioning;
(f)
validation;
(g)
interfaces; and
(h)
any other information reasonably requested by the Principal, or as required by the Rail Commissioner’s
guideline.
5.4
Independent Safety Assessor
The Contractor must engage an ISA to:
(a)
provide an independent professional review of the Contractor’s safety systems and activities;
(b)
independently verify the Contractor’s Systems & Safety Assurance Plan;
(c)
independently verify the safety deliverables for technical quality and suitability; and
(d)
independently verify the Safety Argument ahead of each milestone submission as the basis of providing a
suitable and robust demonstration/defence of the safety being achieved.
The ISA is subject the prior approval of the Principal prior approval, which must not be unreasonably withheld.

CSTR: Part D16 Safety in Design
Within the Safety Management Plan, the Contractor must include the ISA arrangements, the ISA assessment
activities, the ISA's proposed interactions with the Contractor and the ISA's deliverables to the Principal.
The ISA must:
(a)
at all times, be independent of any commercial, financial or other conflicts with any party to this contract;
(b)
ensure that there is a balance of direct evidence (for instance, from assessment of evidence obtained from
analysis, test or review) and indirect evidence (for instance, from checking the definition and compliance to
processes for risk assessment, development; and
(c)
ensure that all parties are informed of any safety issues arising.
5.5
Safety Assurance Argument
The Contractor must prepare a Safety Argument in a Goal Structuring Notation (GSN) format approved by the
Principal that demonstrates the safety of each Operable Stage, Section and of the final System.
The primary purpose of the goal structure is to show how goals (claims about the system) are successively broken
down into sub-goals until a point is reached where claims can be supported by direct reference to available evidence
(solutions). As part of this decomposition, using the GSN, the Contractor must make clear the argument strategies
adopted (e.g. adopting a quantitative or qualitative approach), the rationale for the approach and the context in which
goals are stated (e.g. the system scope or the assumed operational).
5.6
Safety in Design
The Contractor must have a documented Safety in Design procedure outlining their process towards managing
design implications in construction, operational and demolition phases of the project.
A Safety in Design risk assessment must be developed for the project and proposed safety controls must be
forwarded to the Principal at the Notional 30%, 70% and 100% design review stages in the process.
In undertaking the Safety in Design process, the Contractor must:
(a)
establish the context for the design;
(b)
identify the foreseeable uses of the design;
(c)
identify hazards relevant to the phase of the project;
(d)
undertake an assessment of risk;
(e)
develop the Safety in Design risk assessment;
(f)
identifies potential control measures and determine residual risk based on the So Far As Is Reasonably
Practical (SFAIRP) legal principle;
(g)
monitor and review the design process at critical stages (30%, 60% and 95%); and
(h)
communicate and consult with the Commissioner regarding Safety in Design.
The Design Risk Register is a Controlled Document and submission to the Principal shall constitute a HOLD
POINT.
