For the former, qualified technical personnel must either select and/or tailor an existing specification for the
items required or create a new one if an appropriate one does not exist. The specification must reflect two
types of safety data:
· Performance parameters (e.g., acceptable risk levels, specific safety criteria such as
electrical interlocks)
· Test & Evaluation Requirements (e.g., specific safety tests to be performed and/or specific
program tests to be monitored for safety.

Traditionally, administrative requirements have been specified in the request for proposal. MIL-STD-882D
has taken a position that given the technical requirements, defining the administrative requirements can be
left to the bidding contractor to define as part of the bidding process. The proposal evaluation team will
judge the adequacy of the proposed safety program. Inadequate proposed safety programs can either be
judged not-responsive or amended during negotiation.
The following administrative requirements must be defined and included in the negotiated contract and/or
Statement of Work (SOW):
· Delivery Schedule (e.g., Schedule of safety reviews, analyses, and deliverables. It is suggested
that delivery be tied to specific program milestones rather than calendar dates e.g., 45 days
before Critical Design Review).
· Data Requirements (e.g. Number of safety analysis reports to be prepared, required format,
content, approval requirements, distribution.)
Another valuable element of acquisition planning is estimating contractor costs of safety program elements
to assist in:
· Determining how much safety effort is affordable; and is it enough?
· Optimize the return on safety engineering investment.
· Perform a sanity check of contractor's bids.
6.2.2 Development and Distribution of a Solicitation
To transmit the requirements to potential bidders, an Invitation for Bids, (if the Sealed Bidding method is
used), or a Screening Information Request (SIR) Request for Proposals (RFP), if a competitive proposals
process is used. These documents contain the specification (or other description of the requirement), data
requirements, criteria for award, and other applicable information. For some programs with complex
safety interfaces (e.g. multiple subcontractors), or high safety risk the IPT may require the submission of a
draft System Safety Program Plan (SSPP) or Integrated System Safety Program Plan (ISSPP) with the
contractor's proposal. The purpose is to provide evidence to the FAA that the contractor understands the
complexity of the safety requirement and demonstrates the planning capability to control such risks. In
those cases, where the responsibility for defining the SSP's administrative elements has been assigned to the
contractors, the inclusion of a draft SSPP or ISSPP with the proposal is essential.
Each solicitation contains at least three sections that impact the final negotiated SSP:
· Equipment Specification
· Statement of Work (SOW)
· Instructions for preparation of proposals/bids and evaluation criteria. (Sections L and
M respectively)
6.2.3 Equipment Specification
Specifications are the instructions dictating to the designer the way the system will perform. A system
specification is prepared for all equipment procured by FAA. The system specification and more detailed
requirements that flow down to lower level specifications define design requirements. The careful selective

use of FAA and Military Standards can simplify the specification of design criteria. For example, FAA-G-
2100F provides physical safety design criteria. MIL-STD-1522 contains specific instruction for pressure
vessels, placement of relief valves, gauges, and high-pressure flex hose containment. MIL-STD-454,
Requirement 1 specifies design controls for electrical hazards and MIL-STD-1472 for ergonomic issues.
Whether these specifications are contractor prepared or supplied by the managing activity, it is important
that proper instructions are given directly to the designer who controls the final safety configuration of the
system.
MIL-STD-490 gives a format for preparing universally standard types of specifications. Appendix I of
MIL-STD-490 identifies the title and contents of each paragraph of the system specification. Other
appendices describe other types of specifications, such as prime item development, product, and so on.
