Genoa Bridge Tragedy: Who’s responsibility is it?

The Genoa Bridge Tragedy. The question of responsibility.

 

The Genoa Bridge Tragedy: On 14 August 2018, a viaduct – a major motorway, constructed in the 1960s in the north of Italy, collapsed, killing 43 people. Cars, trucks and people dropped suddenly, crashing to the ground 150 metres below. Sounds surreal in this day and age. But it did happen.

Once the initial shock subsided and emergency efforts completed, the attention turned to questioning – just how did this happen?

A “cable-stayed bridge”, the design featured two pretensioned concrete cables used on both sides of the pillar.  According to an article on Archinect.com, the design, “subject to corrosion, it may have made the bridge, which required constant maintenance as an essential traffic hub, vulnerable to collapse.”

An engineer who worked for the company that constructed the bridge claims that the bridge’s supporting piles weren’t built with anti-seismic materials and did not have the capacity to support the weight of heavy traffic.

As reported on News.com, the engineer that designed the bridge “warned four decades ago that it would require constant maintenance to remove rust given the effects of corrosion from sea air and pollution.”

The power of hindsight

Again, hindsight rears its ugly head with a raft of finger-pointing and mismanagement claims. Ultimately a formal investigation into the Genoa Bridge Collapse will look at a range of possible causes including materials used, wear and tear, heavy traffic, structural flaws, poor maintenance budgets and other problems. It raises an important topic for conversation and action.

The considerations for design components of structures spans well beyond the initial construction and ready for use stage. It shows the importance of understanding lifetime usage, maintenance and ease of access, the sustainability and resilience of materials to the elements, and long-term maintenance budgets.

And, ultimately asks the question. “Who’s responsibility is safe design?”

Responsibility for Safe Design

Responsibility for Safe Design

Whose responsibility is it to ensure design safety?

 

Responsibility for safe design.

The biggest mistake many building design and architectural practices make is assuming they do not need to do anything in relation to their duties under work health and safety (WHS) legislation.

The reality is that designers in most states and territories throughout Australia have a legal duty to design structures, so far as is ‘reasonably practicable’, that are without risk to health and safety when they are used as, or at, a workplace.

Designers need to make sure that they are protecting themselves and their practices and the people who are going to use the buildings or structures they design. Designers need to understand their duties under legislation and what they need to do to comply with these duties.

The good news is that it is easy to comply with legislation once you have processes in place.

How can designers meet their legislative requirements?

Designers can meet their legislative requirements for work health and safety by:

  1. Reading the Code of Practice: Safe Design of Structures and other WHS codes of practice.
  2. Training staff in safe design and legislative requirements.
  3. Researching WHS Injury statistics and specific data relating to the structure being designed.
  4. Consulting with the client, workers, engineers, plant designers, specialist operators (e.g. crane operators) and the principal contractor.
  5. Implementing a safe design procedure for their company and a systematic process for identifying hazards.
  6. Designing structures to be without risk to health and safety.
  7. Facilitating safe design workshops with key stakeholders.
  8. Preparing safe design reports and other supporting documentation.
  9. Engaging a safe design specialist like Safe Design Australia, to assist them with the above where required.
  10. Having an internal WHS procedure for staff.

 

Flexible and convenient online training for safe design

We know safe design ‘sounds’ boring. But it doesn’t have to be. We’ve developed a flexible and convenient online training course specifically focussed on Safety in Design (SiD) for design professionals – architects, building designers, engineers and other building professionals.

The online course has been designed by international safe design expert and WHS professional, John Daly, and is endorsed by the Safety Institute of Australia (SIA). It provides the latest information, advice and tools relating to safe design practices in Australia, New Zealand and around the world.

SDA - Safe Maintenance Affinity Water UK Safe Design

Case Study: Affinity Water, United Kingdom

Case Study: Safe Maintenance for Affinity Water, United Kingdom


Innovative office design for safe maintenance

This building was designed for Affinity Water in Hatfield Business Park in the United Kingdom. Safe maintenance was a key component in the design considerations.

The client wanted a statement building that would:

  • reflect their corporate ethos,
  • promote collaborative working, and
  • energise their staff.

The building was designed using an innovative combination of environmental design and safe design. As a result, it has created a positive environment for the employees using the building every day, as well as a safe environment for maintenance workers.

Considering safe maintenance during the design phase

The designer of this building, Scott Brownrigg Architects, considered safe maintenance of the structure by integrating edge protection and platforms into the facade for cleaning of windows. These platforms are accessed by the external fire stairs, so there’s no disruption to the office workers’ daily roles.

A full height statement winter garden was incorporated into the design, with the garden surrounded by glass to to add extra visibility and improve the internal environment for workers. To aid in cleaning, a special scissor lift was developed, enabling workers to access the large areas of glass. At ground level, a path was also incorporated around the perimeter of the building to facilitate safe maintenance using the proposed mobile plant.

Accessibility and safety at height

To allow for safe access to the plant, which was located on the roof of the structure, the designer incorporated an integrated parapet to provide permanent edge protection. This feature has eliminated the need for temporary edge protection and fall protection equipment during maintenance of the roof plant. The parapet was concealed behind the awning so it didn’t affect the visual or sun shading effect of the feature awning around the roof.

Safe Design Workshop with project stakeholders

Safe Design Australia acted as the safe design consultant for this project, providing support in consultation and workshops. Safe design workshops are important, particularly for more complex projects as they can assist the designer in identifying hazards and consulting with other duty holders on ways to eliminate or minimise risks.

Participants can include the designer, the client, engineers, consultants, principal contractor, maintenance manager, employer (or workers representative) at the workplace being designed and other consultants.

Duties of designers under safe design legislation

Duties of Designers – Safe Design

Duties of Designers under Safe Design legislation

 

‘Safe design’ of structures involves designers preventing potential injuries by
considering safety throughout the design process.

Analysis of fatal accidents on building sites show that many are due to shortcomings in design as well as organisational problems. So what are the duties of designers during the design process to ensure they meet safety in design requirements?

In the early stages of a project, there is greater scope to remove foreseeable hazards through design. Prevention is the most effective and affordable way to improve the safety of workers and requires the least effort compared with making changes at later stages.

Duties of designers as ‘upstream duty holders’

Designers of structures are known as ‘upstream duty holders’ and make decisions every day, as part of their expertise, which affect the safety of the people who work on, or in, these structures further ‘downstream’ in the structure’s lifecycle.

These include people who construct the structure, who use the structure for the purpose for which it is designed, who maintain the structure, or who demolish the structure at the end of its life. It also includes the safety of people in the vicinity of the structure. That’s a lot to think about!

Concerns about safe design legislation

So, just what are designers concerns about safe design legislation, and are they justified?

An online poll conducted by Safe Design Australia^ showed, alarmingly, up to 44.5% of those surveyed had a lack of knowledge about the legislation, with a further 31.5% having a fear of prosecution under the legislation. 19% of those polled felt that it restricted their creativity, and only 5% had no concerns.

Understanding WHS obligations and legislation

Knowledge of safe design is relatively low industry-wide. The majority of designers have no formal education in this area. And, research has shown that while designers of structures may be aware of safe design legislation, very few can nominate their specific obligations under the legislation.

It is important that designers understand safe design legislation and how to incorporate safe design into their standard design process.

Learning and understanding the current legislative requirements is the best way to overcome any concerns about safety in design.

Why is safe design important?

It is important to remember that the intent of the legislation is to improve the safety of workplaces, not to prosecute designers. Designers can protect themselves by discharging their legislative duties and by designing structures to eliminate or minimise risks to health and safety.

Designers have the opportunity to make a difference to the health and safety of workers and end users of structures through safe design. By approaching safe design with innovation and creativity, designers can create safer workplaces without compromising the integrity of their designs.

Benefits of safe design*

There are a number of benefits to safe design including:

  • preventing injury and illness,
  • improving usability of structures,
  • improving productivity,
  • reducing production and operational costs, and
  • encouraging innovation.

And, most importantly, saving people’s lives!

How can designers learn about their safe design obligations?

Let’s be honest – no one gets excited about safety. But what if it wasn’t boring? The team from Safe Design Australia have developed a flexible and convenient online training course specifically focussed on Safety in Design (SiD) for design professionals

The online course has been designed by international safe design expert and WHS professional, John Daly, and provides the latest information, advice and tools relating to safe design practices in Australia, New Zealand and around the world. It’s easy to access and can support your Continuing Professional Development.

Case Study - Safe Design Considerations for Childcare centres

Case Study: Childcare Centre Safe Design Considerations

Case Study: Childcare Centre Safe Design

This case study is a compilation of issues from several different childcare projects. 

 

Identifying hazards during the design phase

Every project has its own unique considerations, and in this particular project, the design brief required the conversion of an existing structure – a three storey building – into a large multilevel childcare centre.

The existing building had been built in the 1960s and as such had historical construction aspects to consider. The designer undertook a visual inspection and identified asbestos and lead based paints had been used in the original construction. As a result, project managers organised a hazardous materials survey, which confirmed the presence and the location of the hazardous substances.

It was determined that the hazardous materials would be removed during the construction of the childcare centre.

Across the road from the site, was a power generation plant which posed issues around the health effects of electro-magnetic radiation (EMR). The designer subsequently took this potential health issue into consideration and researched various claddings and glazing which would reduce exposure of EMR to occupants of the new building.

Including outdoor areas into design

There is strong evidence that shows the importance of outdoor play in childcare environments and the client wanted to ensure that this was included as a key component in the design of the childcare centre. The designer incorporated this into the framework of the existing structure and achieved the inclusion of outdoor spaces by creating large balconies on each level. This did, however, create potential significant hazards including the possibility of children moving and climbing on outdoor furniture and falling.

The designer used ‘safe design’ principles to address this hazard, increasing the balustrading above the standard required height to 1.6 metres and also specifying glass balustrading without footholds. Other safe design measures included the specification of soft fall and shading for the outdoor playground equipment and large windows to provide greater visibility from internal staff areas.

Garden beds were located in these outdoor areas, taking into consideration the location of the plants and types of plants, to ensure they were out of reach of children, and most importantly, non-toxic if ingested.

The designer also undertook research into the types of treatments possible for the feature timber balcony posts to eliminate the chance of splinters and ensure materials used were non-toxic to children.

Greater visibility and sightlines for interiors

The reception area was located in a position that provided clear visibility and surveillance of people entering the childcare centre, with access controlled by secure glass doors to prevent unauthorised people from entering the centre. A sign-in area for parents was also considered in the design process.

The layout design included separation and soundproofing of the baby area from the toddler area, clear sightlines from baby nappy change stations and food preparation areas to play areas to allow staff to supervise others while undertaking these tasks.

A central staff control area was provided to allow for supervision of each group.

Additional hazard identification and minimisation

Heat sources such as the hot water system and oven were isolated from children to avoid potential harm. A lockable cleaners’ storeroom was provided to store cleaning chemicals and equipment. The designer specified no volatile organic compounds paints and low emissions joinery and carpets to prevent the potential health effects from the off gassing of these products, particularly for those children with Asthma. This also had the added benefit of providing safer products for construction workers during the construction stage.

Greater accessibility for maintenance and site users

Plant was relocated from the roof to ground level to allow for easy access for maintenance purposes. Some air conditioning units were located on the balcony area, but these were located away from the edges and in a screened area. The openings in these screens were resized during the design process to eliminate the potential hazard for hand and finger entrapment. Windows were openable from the inside to allow for easy cleaning, but were secured to prevent access by children.

The original basement car park design did not incorporate pedestrian paths and research indicated this was a significant hazard in childcare centres. The design was revised to include pathways with wheel stops in front of the car spaces, and one-way traffic to allow for better traffic flow.

Managing potential emergencies

To facilitate the evacuation of babies during a potential fire emergency, fire safety cots were specified and a room provided for their storage in an appropriate location. The babies would be placed in these cots to be evacuated by staff. To prevent children from exiting through the fire safety door, it was programmed to only unlock when the alarm was activated. The designer also consulted with the workers’ WHS representative on the proposed safe lock down procedure for the centre to ensure that areas could be safely secured in the event of a lock down in an emergency situation.
