Case Study: Safety in Design for Residential Structures

Case Study: Safety in Design for Residential Structures

Safety in Design for Residential structures

This case study for safety in design for residential structures is a compilation of design planning and structure issues from several different residential building and renovation projects.

The designer was commissioned to renovate a coastal house, including the addition of a second storey, an upper storey balcony, an entry void and stair, and some internal upgrades.

Site factors considered were the presence of overhead power lines and underground gas, the instability of the slope (geotechnical report required), and the potential for acid sulphate soils (acid sulphate soils study required).
The designer identified the potential presence of asbestos, lead based paints and polychlorinated biphenyl (PCBs) in the existing structure, and organised a competent person to confirm the location of these hazardous substances. The designer and client discussed the asbestos and decided that it should all be removed as part of the new works.

As the additions included a new upper storey on top of the existing structure, the designer consulted with a structural engineer to verify the capacity of the structure to take the load of the new level and any additional support that would be required to ensure the stability of the structure. As the site was in a coastal area, the engineer investigated the existing structure to ensure that prior damage from corrosion would not affect the integrity of the structure.

During the documentation stage, the spacing of the roof trusses for the upper level was revised to 600mm centres with battens at 450mm centres to reduce the risk of falls during construction. The roof pitch was kept below the critical angle of 26 degrees at 22 degrees (see Code of Practice: Preventing Falls in Housing Construction) to improve worker safety.

To reduce exposure of the construction workers to hazardous substances, the designer specified paints and adhesives that had no volatile organic compounds (VOCs) and no emissions materials for internal joinery.

New materials were selected for durability and to reduce the need to maintain the building at heights including the use of stainless steel roof sheeting and fixings. Air conditioning units and fans were selected that were more durable for the environment. Air conditioning units were located to the rear of the residence for protection from salt spray and at ground level for easy maintenance. To increase durability and reduce the need for ongoing maintenance, the designer selected a tiled concrete slab for the rear veranda, durable composite decking made from recycled plastic for the entry deck, and stainless steel balustrading. To eliminate confined spaces, rainwater tanks were selected that did not have to be entered to be maintained.

High level windows were originally proposed over the staircase and were considered a potential hazard for maintenance. These windows were relocated over a hallway where they could be accessed for cleaning. Louvres were specified on the upper storey to allow cleaning from the inside. Wall mounted LED lighting in the void area was proposed to reduce the risk of work at height for lighting maintenance.

The designer eliminated or minimised risks—so far as was reasonably practicable—and communicated residual risks to others further down the lifecycle including the principal contractor, maintenance contractors and demolition contractor in the safety report. The designer provided the safety report to the client, who was advised to provide this to the principal contractor. This report was also issued by the designer with tender documentation and submitted with the plans to the local council.

Safe Design Workshop with project stakeholders

Safe Design Australia acted as the safe design consultant for these residential projects, providing support through 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 (sometimes the building owner), engineers, consultants, principal contractor, maintenance manager and other consultants.

Genoa Bridge Tragedy

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.

Safe design. Marshall Hotel, Taiwan earthquake.

Safe design. The benefit of hindsight.

The benefit of hindsight. Changing outcomes for the future.

Safe design. The benefit of hindsight…

In February this year, a 6.4 magnitude earthquake hit regions of Taiwan. The image of a propped up Marshall Hotel in Huelin did the rounds on social media.

Many thought this image was comical (particularly without background of what happened) and sadly, many people lost their lives that day.

Earthquakes can’t be avoided. Every environment, region or structure, however, has its own unique circumstances or considerations, and regardless of whether it’s manmade or natural, risks can be minimised or in many cases, eliminated.

How could the application of safe design practice changed this outcome?

Consultation and collaboration with specialists to consider Safe Design throughout all phases of the design, construction and usage stages of a structure are important to ensure we continually innovate and improve, while also preventing and minimising injury through the design of safe structures and workplaces.

Emergency workers went to alarming lengths in this instance. And, we don’t have the complete view of the design, development and construction lifecycle for this project. But, do you think the outcome could have been any different in this situation?

Precast concrete panel collapse

Structure and Process Design. Why are we getting it wrong?

Construction incident causes death of two workers

What can we learn about structure design and the safe design process?

In October 2016, two workers employed in a $25 million development at Eagle Farm Racetrack in Brisbane, were killed when an 11 tonne concrete panel fell over and crushed them.

The large concrete drainage structure, consisting of four individual concrete panels (the walls), were progressively being lifted into place with a crane when two panels fell forward, one after the other.

The men narrowly avoided the first panel falling, however they were subsequently crushed by the second panel, causing their deaths.

Structure Design and the Safe Design process. Why are we getting it wrong?

When we see incidents like this one in Queensland which resulted in the two workers being crushed to death, it makes you wonder. How, in this day and age, does this happen?

We can not help thinking about all the possible design solutions that could have been adopted to prevent the two workers being exposed to the precast panels collapsing. It raises the question – did the designer have time to think about this, to consult, to plan and to talk to people with experience? What control measures could have been put in place to mitigate the construction risks?

WorkCover Qld* proposes the following control measures

WorkCover Qld proposed the following in their Safety Alert – Concrete Wall Panels:

“Control measures to prevent such collapse are to be applied before workers enter the pit.

Concrete wall panels should not be erected unless the following has been carried out:    

  • Each wall panel is provided with a minimum of two braces that are attached to the face [1of the panel and anchored to the ground with engineer designed footings.
  • Each panel is provided with an effective way to restrain the bottom of the panel when it is installed.
  • The panel restraint system, including brace footing details, is to be designed and certified by a suitably qualified professional engineer (in Queensland the engineer is required to be a Registered Professional Engineer of Queensland). The engineering certification must be on site.
  • Workers involved hold the appropriate high risk work licence:
  • A comprehensive safe work procedure (i.e. safe work method statement) is to be developed by the panel erector and verified by the principal contractor. Responsibilities of every worker (including the rigger) should be specified in the procedure. 
  • The procedure should include detailed diagrams that include the relative position of the mobile crane to the panels, the sequence of panel installation, and details on the panel restraint system. 
  • Prior to work commencing a pre-start meeting should take place to ensure all workers are familiar with the procedure.”

Safety in Design

This very sad, but serious incident is what Safety in Design (SiD) is all about. Eliminating hazards through good design. We all need to learn from these tragic events.

Case Study Prince Alfred Park Pool Sydney

Case Study: Prince Alfred Park Pool, Sydney

Case Study: Prince Alfred Park Pool, Sydney

“The overriding principle was to premiate landscape over built form, based on a conviction that in these inner urban areas, green space is sacred.”

Source: 2014 Sydney Design Awards submission.

Based on this concept, a main feature of the design of the Prince Alfred Park Pool complex in Sydney was the landscaped grass roof that sits over the pool building facilities. The safe design of this roof required consideration of safety in relation to potential falls as it could be accessed from street level and also consideration of how this roof would be safely maintained.

Designing for safety without compromising design intent

Potential unauthorised access to the roof was addressed by a 2.4 metre high fence that is set back from the edge so it doesn’t impact on the intended visual effect. This fence is angled back and has no footholds, preventing climbing. The architect incorporated security lighting, CCTV and an alarm back to City of Sydney Security. The landscape designer reduced the need for maintenance by proposing an irrigation system and the specification of native grasses so that no mowing was required. An integrated cable access system was incorporated into the design to enable maintenance of the plants for weeding. In addition, a wide coping provides edge delineation and is illuminated by lighting from the pool deck below.

To ensure safe maintenance of the structure and associated plant, the designer consulted extensively with the plant designers and design engineers. The project incorporated a concrete plant hatch above the plant rooms, fitted with lifting points hidden in the grass mound roof, should the need arise for future replacement of plant with a designated crane operation area. Large skylights and tri-generation chimneys, projecting above the grass mound, are not only safe and functional, but are also a great sculptural element – fitting in with the original design intentions of the architect.

Pivoting outdoor light poles allow maintenance access without the need to work at height.

Designated access ways for emergency access were engineered to take the loads of vehicles that may need to access the site. Research and testing was undertaken to select durable materials and surfaces, and also to ensure that surfaces met slip resistance ratings for its proposed use.

The importance of Consultation and Collaboration

Consultation involved a number of safe design workshops led by the safe design consultant with key stakeholders including the client, architect, maintenance personnel and the operator. Outcomes were documented during each stage and the risk register was updated throughout the design process, and also at the end of construction.

An operations and maintenance plan was created at the completion of the project incorporating residual risks and safety controls so that people further along in the lifecycle of the complex could be made aware of safety issues.

Case Study: AIR Apartments, Sydney

Case Study: AIR Apartments, Sydney

Case Study: AIR Apartments, Sydney

This Case Study for AIR Apartments, Sydney shows the importance that a Safe Design Workshop and consultation early in the design development phase can contribute to positive design outcomes and deliverables for a large scale design and construction project.

Located in St Leonard’s CBD in Sydney, the AIR Apartments construction was situated on the site of an existing building that had been demolished. A safe design workshop took place early in the design development phase of the project so that the designer could consider safe design and eliminate any potential hazards early in the project.

Hazard Identification early in the design development phase

The proposed design of the structure incorporated a basement that was to be built to the site boundaries. Hazards associated with potential vibration and effects on the structural stability of the neighbouring structures were discussed and the designer and structural engineer determined an appropriate system of construction to ensure that the basement works wouldn’t adversely impact the neighbouring structures. In consultation with the principal contractor, vibration monitoring was proposed to be used on adjacent structures during construction.

The facade design included the unique feature of large horizontal blades that project from the building. There was the potential for maintenance loads on these blades and an accessibility issue for facade maintenance. Consultation with a facade consultant was recommended and the possibility of an integrated building maintenance unit was discussed. Pre-fabricated facade elements were proposed to reduce the need to work at height and minimise onsite welding during construction.

The challenge of separating public and private use

Another challenge for the project team was the requirement for separation between public and private uses to ensure the security of residents. To address this separation, retail, restaurant and fitness centre areas were proposed at ground level to be accessed directly from the public domain with restricted access via the lifts to the service apartments and private residential levels. Secure access to the car park by the public and tenants was addressed through the provision of a designated area on the first basement level for public parking with CCTV surveillance. Secure residential parking was provided on the lower levels with access via a mechanical boom gate controlled by a swipe card with a security intercom system. CCTV surveillance and security lighting was also provided.

The potential for objects to fall from balconies on to people below was considered and the team determined that this would be further considered through the design development stage with the location and screening of balcony spaces and the use of landscaping below these areas. Safe balustrade heights were also discussed.

Plant and Services considerations

Plant and services considerations included the provision of a plant platform on the roof with keypad entry for security, stair access to allow workers to carry small plant and equipment, and a parapet to reduce falls and protect maintenance personnel from high winds at altitude. Additional secure plant rooms were proposed in the basement area. Bollards were proposed outside lift and plan doors to prevent vehicles blocking access/egress to and from these areas. The waste management system involved the separation of commercial and residential waste. The residential garbage chute system was integrated into the building infrastructure and was designed to reduce the risk of manual handling with inlets provided at each level and with an angled chute and exclusion zones to reduce the risk of objects falling on garbage workers below.

The pool and spa deck is a unique design feature with large circular vision panels between the base of the pool and the foyer below. Further research and testing was proposed to determine safe materials and construction methods as well as safe maintenance. Discussions occurred at the safe design workshop between the designer and engineer on the anticipated plant loads (e.g. scissor lift) required on the suspended slab for maintaining the pool windows above the foyer. A plant room and lockable store for pool chemicals was proposed below the pool deck which led to discussions at the workshop on how the location might be reviewed during the design development stage to reduce the need for manual tasks including carrying of pool chemicals up and down stairs or whether alternative mechanical methods were practicable. The pool area was designed for safe use with a proposed non-climbable 2.1 metre balustrading to prevent falls and falling objects.

The Safe Design Workshop – Design Development Phase

A Safe Design Workshop was undertaken early in the Design Development Phase of the project to ensure that the designer could consider safe design whilst also identifying and eliminating any potential hazards early in the project.

Safe Design Australia led this workshop which influenced the collaboration and consultation between the designer, engineer, facade consultant and other building design and construction professionals throughout the design and development of AIR Apartments.
