Access control and how it is changing construction

Biometric authentication, AI integration, cloud-based access systems and automation are shaping the construction industry by improving safety, streamlining processes and aligning with the increasing push for sustainability. These systems, which include fingerprint scanners, facial recognition and retina scans, are particularly transforming access control on construction sites, but unlike traditional keys or swipe cards that can be misplaced or duplicated, they provide instead a personalised and foolproof method of identifying individuals – and it is changing the face of construction - writes John Ridgeway.

They are bringing enhanced security, ensuring that only authorised personnel can access restricted areas and are helping to reduce theft and trespass incidents. Biometric systems that can log workers' entry and exit times, are providing accurate records for payroll and compliance and because they ensure workers can only be granted access to specific areas based on their role, they are also delivering better safety protocols.

Artificial intelligence (AI) and machine learning in particular have become powerful tools in access control. These technologies provide real-time data analysis, helping construction sites identify potential threats and inefficiencies. Machine learning algorithms monitor entry patterns to flag suspicious activity and AI-powered cameras detect unauthorised personnel or unusual movements, alerting security teams instantly. These systems can also predict when equipment, such as gates or locks, might fail, preventing costly delays. Click link to read more:

The impact of organised crime on South Africa’s construction industry

In recent years, South Africa’s construction industry has faced a growing crisis from organised crime groups. The so-called "construction mafia" have created an environment of fear and uncertainty, using extortion, violence and intimidation to force building companies and workers into submission. It’s a problem that has led to financial losses and stalled infrastructure development as well as endangering the lives of those who work on construction sites across the country, writes John Ridgeway.

The "construction mafia" in South Africa began to gain attention around 2014. Organised crime groups, largely gang-affiliated, began to infiltrate the construction industry, particularly in government-funded infrastructure projects. These gangs use tactics commonly associated with traditional mafia activities, including demands for "protection fees" or a share of project budgets, especially on public works and housing projects. If construction companies do not comply, these groups often resort to violent methods, which can include assault, threats to workers and management, or property damage.

In many cases, gangs demand up to 30% of a project's value as a fee. While they justify these demands under the guise of community involvement or job creation for locals, their true aim is control over lucrative contracts and revenue streams. Often, these gangs insist that contractors employ their affiliates or members from local communities, thereby ensuring a portion of wages and influence within the project. The most notorious cases have been reported in regions such as Gauteng, KwaZulu-Natal, and the Western Cape, where these gangs operate with near impunity, undermining efforts to complete vital projects​

The presence of the construction mafia has a twofold effect on the industry. First, workers, engineers, and managers on-site are exposed to frequent intimidation and life-threatening situations, which detracts from productivity and morale. Companies operating in regions heavily affected by these gangs must make difficult choices - either comply with the gangs’ demands or face the risk of shutting down projects. In Cape Town, contractors on several housing developments abandoned projects entirely due to sustained harassment and violence from local gangs, some of which have close ties with influential criminal networks​.

Exploring the global market for glass fibre reinforced concrete

The global glass fibre reinforced concrete (GFRC) market is booming, driven by rising demand from both commercial and residential sectors and bolstered by trends toward sustainable construction. GFRC, a composite material composed of fine sand, cement, water and alkali-resistant glass fibres, is highly valued for its lightweight, durable and sustainable characteristics and is a proven winner for the construction industry, writes John Ridgeway.

In 2023, the GFRC market was valued at approximately $3.51 billion, with projections estimating it will grow to $3.97 billion by 2024, reflecting a compound annual growth rate (CAGR) of 13.2%. With estimates pointing to the market reaching $6.65 billion by 2028, GFRC is quickly becoming the must have material in the global construction industry.

The surge in demand for GFRC is supported by a range of factors, primarily urbanisation, the demand for more renovation projects and an increasing focus on sustainable building solutions. GFRC is particularly beneficial in green building initiatives because of its composition. The material is not only lightweight and durable, but it also requires fewer resources for transportation and handling. These characteristics make it a perfect fit for green buildings, which aim to reduce the environmental footprint of construction projects. Given that GFRC also offers improved energy efficiency, it has become increasingly popular in eco-friendly buildings and developments globally. Click link to see more:

Empowering women in construction to overcome microaggression

Despite massive progress in diversity and inclusion, a new study in Australia shows that it is still tough for women looking to make a career in construction. The findings reveal that many still experience persistent microaggressions and encounter significant hurdles in advancing their careers – situations that are so difficult - that some are even considering leaving the industry altogether, writes John Ridgeway.

The study, by the National Association of Women in Construction (NAWIC), launched in collaboration with the DEI consultancy TDC Global, highlights the daily challenges that women encounter in the field – and it does not make for good reading. Even worse, there is strong evidence to suggest that their findings highlight a global problem for the construction industry

One of the study's most troubling findings is that 88% of respondents reported experiencing microaggressions, with women in managerial or administrative roles encountering even higher rates. Beyond the emotional toll, these subtle but harmful behaviours can create a pervasive sense of exclusion, undermine confidence and over time, contribute to mental health issues. For many women, fear of retaliation and a lack of institutional support prevent them from reporting these incidents, claims the report, leaving them feeling isolated and undervalued.

NAWIC, founded in Australia in 1995, has become a powerful advocate for women in construction, offering support, resources, and networks that help women thrive in this field. NAWIC is part of a global network that includes the United States, New Zealand, and Canada, and serves as a forum for women to share ideas, expand their skills and create networks that foster personal and professional growth. NAWIC’s vision is to empower women in construction, build confidence and strengthen the industry as a whole through inclusivity and equity. Click link to see more:

The Line and its potential impact on global construction

Saudi Arabia’s NEOM project is reshaping the conversation around urban planning, sustainability and global resource demands. This futuristic city aims to redefine the urban landscape, presenting an ambitious vision of a zero-emission, hyper-connected world. However, alongside its forward-thinking design comes an immense demand for construction materials—particularly steel. Recent reports suggest that this new mega city could require up to 20% of the world’s steel production, a staggering claim that raises questions about its impact on global material markets, prices and availability.

The new mega city – or The Line as it is known - is part of the $500 billion NEOM project, a vast new city that will stretch for 170 kilometres across Saudi Arabia’s northwest region. Designed as a zero-carbon, sustainable urban environment, it is intended to house nine million people in two parallel buildings rising 500 metres above sea level. Each building is expected to be lined with mirrors and will rely on renewable energy sources, such as wind and solar, to power its infrastructure.

The project’s vision is ambitious, but the scale is almost unfathomable. Building a city of this magnitude requires massive amounts of materials. Recent reports suggest that The Line alone could require a significant portion of the global supply of steel—up to 20% of annual production. This revelation was made by NEOM's chief investment officer during an interview with Arabian Gulf Business Insight, stating that NEOM is set to become the largest consumer of construction materials globally for possibly decades to come.

Steel is a core component in construction, offering strength and durability. Globally, around 1.9 billion metric tons of steel are produced annually. For NEOM's The Line to require 20% of that production means it could consume approximately 380 million metric tons of steel over the project's lifespan—a quantity almost equal to the annual production of major steel-producing countries like India and the United States.

The sheer scale of this demand is bound to have ripple effects across global markets. Increased demand often leads to higher prices. NEOM's consumption of vast quantities of steel could drive up prices globally, especially as the project gains momentum. Steel prices are already volatile due to several factors, including post-pandemic recovery, supply chain disruptions and fluctuating raw material costs. Adding a project of NEOM’s scale to the mix could push prices higher, impacting global construction projects. Click link to read more:

A boost for clean construction and sustainability in the U.S.

With growing awareness about climate change and the need to shift toward more sustainable practices, the U.S. government has taken bold steps to spearhead environmentally friendly construction efforts. Among these is the Federal Buy Clean Initiative, launched three years ago and recently updated by the White House. It is an initiative, which is part of a broader strategy to decarbonise federal procurement practices and promote sustainable building materials and methods across the United States – and it appears to be working-.

The Federal Buy Clean Initiative was initially launched in 2021 with the objective of reducing greenhouse gas emissions across federally funded construction projects. The initiative was aimed to prioritise the procurement of materials, especially carbon-intensive ones like steel, concrete and asphalt, that have lower embodied carbon. Such "embodied carbon" applies to the total emissions generated from the production, transportation, installation, maintenance and disposal of building materials.

Through this initiative, the U.S. federal government, which is one of the largest buyers of construction materials in the world, is using its purchasing power to create demand for low-carbon materials and in turn, it is hoped that this will drive significant reductions in greenhouse gas emissions from the construction sector.

In September 2023, the White House released an update on the progress of the Buy Clean Initiative, announcing a major expansion in both public and private sector participation. This was a significant update as it highlighted several companies and state entities that have committed to the goals of the initiative, including major corporations and key states.

Why the construction additives market is booming

One critical aspect shaping modern construction is the growing use of construction additives - chemical and mineral compounds that enhance the properties of materials like cement and mortar. These additives improve the strength, durability and performance of building materials, making them essential in the development of high-quality infrastructure. It’s a sector that continues to grow, boosted by several factors - ranging from urbanisation to technological advancements – which are all helping to drive this trend - and the only way is up with a market predicted to be worth $120.23 Billion by 2033.

Construction additives refer to chemicals or minerals added to building materials, particularly concrete, mortar and cement, to improve their physical and chemical properties. These additives play a critical role in construction by enhancing the workability, strength, durability and water resistance of materials. By adjusting key characteristics, additives help to ensure the long-term performance of structures, even in harsh environmental conditions.

Some of the most common types of construction additives include plasticisers, which are designed to improve the workability of concrete without adding more water. Then there are superplasticisers, which enhance fluidity and are often used in high-performance concrete. Click link to read more:

How construction noise affects worker efficiency and safety

Noise is an inevitable byproduct of construction and it can have a profound impact on worker efficiency, cognitive function and safety. A construction site is rarely quiet, with sounds that range from low-frequency hums to high-pitched screeches, often combining to create a virtual chaos of noise, but what exactly makes up this soundscape – and more importantly, what should we be doing to quieten things down.

Research has shown that exposure to constant loud noise can have adverse effects on cognitive performance and well-being. On a construction site, the constant bombardment of sound can reduce a worker's ability to focus, leading to diminished productivity and a higher likelihood of mistakes.

Sustained exposure to noise pollution increases stress levels, leading to what experts call "mental fatigue." This occurs when the brain, constantly working to filter and manage noise, becomes tired. This state of tiredness impairs cognitive function, making it difficult for workers to focus on tasks or absorb critical information. For workers operating heavy machinery or following complex procedures, this lack of focus can result in errors, delays and even accidents.

A recent study published in the Journal of Occupational and Environmental Hygiene showed that individuals exposed to high noise levels over an extended period demonstrated reduced cognitive function, including memory recall and decision-making capabilities. On construction sites, where precision and clear thinking are paramount, this cognitive decline can significantly affect productivity. Click link to read more:

The inspiration behind a different kind of future for construction waste recycling

One person's trash is another person's treasure – is an age-old adage that has taken on a new, sustainable form with the launch of an innovative recycling initiative for the construction industry on Vancouver Island, British Columbia, Canada. It is called the Building Material Exchange (BMEx) programme, a forward-thinking solution that allows construction companies to sell or swap leftover materials from job sites instead of sending them to landfills – a move so revolutionary, it could transform the construction industry if it was adopted worldwide.

Launched by Light House, a Vancouver-based non-profit company, dedicated to enhancing sustainability in the construction sector, BMEx represents a major shift in how the industry manages its waste. It ensures that the benefits of construction waste recycling extend beyond the immediate environmental impact, offering cost savings and community benefits - and could be the model that revolutionises construction and waste management practices across the globe.

Construction waste is one of the largest contributors to landfills worldwide. In Canada alone, the construction industry generates approximately 3.4 million tonnes of waste annually, much of which ends up in landfills. The construction industry generates an estimated 1.3 billion tonnes of construction waste annually worldwide, according to data from multiple sources. This number is anticipated to increase significantly in the coming years. For example, the World Bank projects that by 2025, global construction waste could reach 2.2 billion tonnes annually, driven by rapid urbanisation, population growth and increased infrastructure development, particularly in developing countries.

Understanding construction site monitoring systems

The construction industry is experiencing a digital revolution and at the heart of this transformation is the fast-expanding monitoring system market. In recent years, it has experienced significant growth, expanding from $1.82 billion in 2023 to $2.11 billion in 2024, delivering a compound annual growth rate (CAGR) of 16.0%. This remarkable expansion reflects the increasing demand for improved safety, efficiency and real-time monitoring of construction projects – and it will play a critical role in shaping the future of the construction industry.

A construction site monitoring system is a combination of hardware and software tools used to manage and supervise activities at construction sites. These systems typically involve cameras, drones, sensors, artificial intelligence (AI), machine learning (ML) algorithms and cloud-based platforms, which is discussed later, in more detail. The primary purpose is to ensure operational efficiency, improve safety, minimise project delays and reduce risks on-site by enabling real-time data collection and communication.

The demand for these systems has surged in recent years due to various factors, most particularly, the need for real-time monitoring. Construction sites often face dynamic challenges and having a system in place that provides real-time data ensures that project managers can respond quickly to any issues.

With heightened emphasis on worker safety and stringent regulatory requirements, construction monitoring systems also help mitigate risks and ensure compliance with health and safety standards. By offering greater oversight and predictive analytics, these systems further help construction companies reduce project delays and cost overruns. Click link to read more:

The rising demand for modular bamboo in construction

Bamboo continues to emerge as a game-changing material for the construction industry - one that combines sustainability, strength and versatility, according to a recent report by Allied Market Research. The sector is set for explosive growth, projected to rise from $1.2 billion in 2022 to an impressive $1.8 billion by 2032. With a steady CAGR of 4.6%, this surge is driven by increasing investments in eco-friendly infrastructure and the growing recognition of bamboo's environmental and structural advantages.

As both emerging and developed economies invest more heavily in construction, there is a growing demand for sustainable building materials that are both cost-effective and environmentally friendly. Bamboo, with its rapid growth rate, durability and sustainability, offers a viable alternative to traditional construction materials like timber and steel. As a result, it is becoming an increasingly popular choice in residential, commercial and industrial applications.

Unlike timber, bamboo grows rapidly, reaching maturity within three to five years. This makes it a highly renewable resource, as it can be harvested frequently without deforestation concerns. Bamboo also plays a crucial role in carbon sequestration, capturing more carbon dioxide than many other plants, contributing to lower greenhouse gas emissions. The environmental advantages of bamboo are driving its demand as part of the global shift towards green building practices and sustainable construction. Click the link to read more:

The importance of regular flat roof maintenance

Regular maintenance has always been essential to ensure the longevity and performance of every flat roof installation and it seems that there is now a growing awareness of its importance. Building owners and property managers are becoming more proactive in scheduling regular inspections and maintenance – possibly because building regulations may require the need for such action, particularly for commercial properties – so why then are so many clients still reluctant to embrace a maintenance programme?

The short answer is probably cost, even though many flat roof warranties require and insist on regular maintenance clauses, if they are to remain valid. However, in spite of potential cost issues, homeowners and businesses are increasingly recognising the long-term benefits of flat roof maintenance, which can help to prevent expensive repairs in the future and extend the lifespan of the roof.

Specific statistics on the percentage of clients choosing or ignoring flat roof maintenance packages are not available. What we do know, however, is that neglecting flat roof maintenance can lead to a range of problems, including leaks, water and structural damage, increased energy costs and even safety hazards.

Why has the EU delayed its asbestos screening programme?

Asbestos, a naturally occurring mineral fibre with known carcinogenic properties, continues to pose a significant threat to public health. Despite its ban in the UK and many other countries, asbestos-containing materials (ACMs) remain prevalent in older buildings and exposure to asbestos fibres can lead to serious health consequences – so why then has the EU delayed the launch of its screening programme?

Mesothelioma, a particularly rare and aggressive form of cancer caused by asbestos exposure, has seen a concerning increase in recent years. The UK Health Security Agency (UKHSA) has recently reported a significant rise in mesothelioma cases, highlighting the ongoing dangers of asbestos. EU sources report cases up 10% year on year.

To put this into perspective UKHSA reported in 2017, that twelve thousand lung disease deaths annually were estimated to be linked to past occupational exposures and 18,000 new cases of breathing or lung problems are self-reported as being caused or made worse by work. The legacy of asbestos use continues to dominate mortality statistics, accounting for approximately 40% of annual deaths from respiratory disease. Click link to read more:

Zombie construction sites and their impact across the world

The German housing market is the latest to be plagued by a disturbing phenomenon - abandoned construction sites, or so called "zombie projects" – and the country is not alone. Such unfinished developments, often left in a state of disrepair, are a stark reminder of the many challenges facing not only Germany, but other areas across the world.

Zombie projects have been observed in dozens of different countries over the last 16 years, often driven by a similar range of economic and market conditions. It was noted as early as 2008 in Spain, which experienced a significant number of abandoned construction projects following the housing market crash. Many unfinished developments were left vacant, creating "ghost towns" in some areas.

In the same year, the Irish housing market also faced challenges, with numerous abandoned construction sites becoming a common sight. The government even established a "bad bank" to deal with these unfinished projects. The Irish housing market, had actually experienced a significant boom in the early 2000s, fuelled by low interest rates and easy access to credit. However, this boom was unsustainable, and the market eventually collapsed in 2008. The collapse led to a wave of abandoned construction projects, as developers were unable to complete projects due to a lack of financing and declining demand.

In response, the Irish government established the National Asset Management Agency (NAMA) to deal with the growing number of abandoned construction projects. NAMA purchased a significant portfolio of distressed assets from banks, including unfinished developments and later worked to complete or sell these projects, helping to stabilise the housing market.

Wall collapse incidents in construction – could more be done?

The Australian construction industry has witnessed a disturbing trend in recent years - an increase in wall collapse incidents. These accidents have resulted in serious injuries and in some cases, fatalities. There are very few statistics available in other part of the world to support this problem, but we know it exists – and you have to ask the question – what are we doing about it.

Over a five-year period, there were 30 notified incidents involving injuries by wall collapses in the construction industry, according to WorkSafe, Australia. This is not a huge number compared to other causes such as falls from height, falling objects and tripping hazards, which is probably why such incidences are largely unreported or registered as something else, but there is plenty of anecdotal evidence from brick layers that new walls can be dangerous and need to be supported.

Several factors can contribute to wall collapse, particularly high winds, which is why most brick layers will brace a wall using timber, until the mortar is properly cured. There are alternatives such as the Brick Bud System from Harris Brick. It’s inventor Carl Harris was inspired to create the system after being injured himself by a wall collapse.

The growing challenge of substance abuse in construction

The construction industry continues to face the challenge of substance abuse. We have been talking about it since 2016 when the Considerate Constructors Scheme first highlighted the problem in a UK survey, stating that some 35% of workers had noticed colleagues under the influence of substances or alcohol. More recently the Substance Abuse and Mental Health Services Administration (SAMHSA) in the USA were telling us that that substance abuse is more prevalent in the construction industry than in other sectors. All the experts continue to tell us that this is a growing problem – so what are we going to do about it – writes John Ridgeway?

Substance abuse among construction workers has now become a pressing issue, with serious consequences for individuals, families and businesses. The most commonly used include alcohol and prescription painkillers, such as oxycodone and hydrocodone. Stimulants like cocaine and methamphetamine can also be a problem in the construction industry. Marijuana is another substance that is commonly used by construction workers.

Here are some of the shocking answers given to the CCS all those years ago and things have not improved –

• 35% have noticed their colleagues under the influence of substances and alcohol

• 25% agreed drugs or alcohol affected them at work through tiredness

• 23% agreed it affected them through decreased attention during work

• 19% agreed the affects made them less productive at work

The construction industry and indigenous communities

History has shown that the construction industry has had a significant impact on Indigenous communities, both positive and negative. When done responsibly, construction has helped preserve and celebrate Indigenous cultures and traditions, however, when done poorly, it has damaged sacred sites, disrupted traditional ways of life and has contributed to environmental degradation.

Indigenous communities have a deep connection to the land, often rooted in spiritual beliefs and cultural traditions. Sacred sites, places of spiritual significance or cultural importance, are an integral part of this connection. Construction projects, if not carefully planned and executed, can have devastating impacts on these areas, causing irreparable harm to cultural heritage and spiritual well-being.

This can be a problem for modern builders as sacred sites can vary widely in their physical characteristics and cultural significance. Some examples include cemeteries and burial grounds, often considered sacred places of rest for ancestors.

Mountains, rivers, forests and other natural features can also hold spiritual or cultural significance for Indigenous communities. Likewise, places associated with major events or figures in Indigenous history may also be considered sacred. Such sites may serve as gathering places, centres of learning, or are used for spiritual practices. Click the link to read more:
