Join us for our next online webinar, The symbiosis between Safety and Requirements Management on the City Rail Link project.

The design team started Safety in Design workshops during definition design, with regular updates all through concept design and detailed design. Hazards were identified, mitigations were proposed and evaluated according to the hierarchy of controls, with elimination being the primary goal. Accepted mitigations were captured in the SiD register and implemented in the design. The requirements team sat in the other side of the office, furiously wrote thick documents containing weirdly-worded requirements and made untimely requests for design compliance. The beautiful design was handed over to construction, who implemented most of it. A few minor changes were made, mainly value engineering plus one or two field change requests that enhanced constructability. When it got to handover, an Independent Safety Assessor asked for evidence that the identified mitigations – all of them – had actually been implemented. The designers by then had moved on to other projects so there was a furious flurry of activity followed by the realisation that one of the value engineering changes had undone a hazard mitigation.  Could this be done better? Could we manage mitigations from identification through to implementation using a known and proven technique.

Presenter: Steve Dennehy

Steve Dennehy worked in South Africa on radar systems and self-protection systems for military platforms, mainly aircraft, for around 20 years, firstly as a digital designer but gradually moved up through product design to systems engineering. The opportunity arose to work on the Square Kilometer Array (SKA) telescope, initially as systems engineer on the signal processor and later on the SKA infrastructure in South Africa.  Steve moved to Auckland, New Zealand in 2017 to work on the City Rail Link project as requirements manager. He joined Aurecon in mid-2019 as a systems engineer working in the rail sector. Steve’s particular areas of interest is requirements management, within the context of systems engineering.
