Pre-fabrication and robotics: Given the challenges of the Martian environment and the limitations of human presence, pre-fabrication and robotic construction techniques will play a crucial role. On Earth, pre-fabrication involves constructing components off-site and assembling them at the final location. Similarly, on Mars, pre-fabricated modules could be transported from Earth or manufactured using local resources, reducing the complexity and cost of on-site construction. Robotics and autonomous systems will be instrumental in assembling and integrating these pre-fabricated components efficiently.

3D Printing: Additive manufacturing, or 3D printing, holds immense promise for Martian construction. Using regolith as a raw material, 3D printers can create structures layer by layer, eliminating the need to transport bulky construction materials from Earth. The European Space Agency’s MELT project and NASA’s Mars Ice House concept are examples of utilizing 3D printing technology to construct habitable structures on Mars. 3D printing offers the advantage of flexibility, enabling the construction of customized designs and adapting to the specific needs of Mars’ environment.

In-Situ Resource Utilization (ISRU): Leveraging the resources available on Mars through ISRU will be crucial for sustainable construction. Martian regolith can be processed to extract minerals and use them as building materials. Ice deposits found in the Martian poles can be harvested and utilized for water supply, life support systems, and as a raw material for manufacturing construction materials. ISRU will minimize the need for transporting materials from Earth, reducing costs and increasing self-sufficiency.

Habitat Design: Martian habitats must be designed to provide a safe and comfortable environment for humans. They need to withstand the harsh Martian conditions while supporting the physical and psychological well-being of the inhabitants. Design considerations include radiation shielding, thermal insulation, airtight seals, and the integration of life support systems. Habitats may employ underground or partially buried structures to provide additional protection from radiation and temperature extremes. Innovative architectural designs, such as inflatable structures or modular expandable habitats, can maximize habitable space while minimizing launch mass.

Potential benefits and impacts

Human expansion and exploration: Construction on Mars will be a significant milestone in human space exploration. Establishing habitable structures will allow for longer-duration missions, enabling astronauts to conduct in-depth scientific research and explore the planet’s surface more extensively. It sets the stage for eventual human colonization and opens doors to further space exploration, potentially paving the way for future missions to other celestial bodies.

Technological advancements: The challenges of Martian construction will drive technological advancements with practical applications on Earth. The development of autonomous robots, 3D printing technologies, advanced materials, and resource utilization techniques will have broader implications for terrestrial industries such as construction, mining, and robotics. The knowledge and experience gained from Mars construction projects will contribute to innovation and push the boundaries of engineering and space exploration.

Scientific discoveries: Construction activities on Mars can also provide valuable scientific insights. The excavation of Martian regolith and the analysis of local minerals can deepen our understanding of the planet’s geology and the potential for supporting life. Construction sites may serve as testbeds for conducting experiments and studying the effects of the Martian environment on materials, equipment, and human physiology.

In conclusion

The construction of habitats and infrastructure on Mars is a monumental endeavour that requires innovative engineering, adaptation to extreme conditions, and the utilization of local resources. Pre-fabrication, 3D printing and ISRU will play vital roles in achieving sustainable and cost-effective construction on the Red Planet. The challenges and solutions associated with Martian construction will contribute to technological advancements, human exploration, and scientific discoveries. As we continue to push the boundaries of space exploration, construction on Mars represents a crucial step towards the expansion of humanity beyond Earth’s boundaries and the realization of long-held dreams of interplanetary exploration.

The long and winding journey of HS2, still without end

,

Despite having very little public support, HS2 continues to tear its way through our countryside and villages, destroying countless habitats and displacing people from their homes. Those in favour estimate it to create 22,000 jobs over the next few years, while opponents claim it will destroy almost that many jobs. Is the rationale for what has eventually been labelled “a vanity endeavour” still applicable in a post-Covid world? Buildingspecifier.com’s Joe Bradbury discusses:

High Speed 2 (HS2) is currently being funded unwillingly by taxpayers throughout the United Kingdom. The proposals for it were made public in 2010, near the end of the previous Labour administration, and the first phase is scheduled to open in 2026. Yet, it is both over budget and behind schedule. Toxic mix… Nevertheless, opposition to the project is growing, owing to its poor economic case, negative environmental consequences, and better suggestions as to how to spend the money set up for HS2.

A study conducted by the ITV Tonight programme back in 2016 discovered that:

  • Only 15% felt that HS2 is worth £56bn
  • 58% didn’t think it’s a price worth paying
  • 77% of people would prefer that the money was spent in other areas, like the NHS
  • Nearly three-quarters of people thought HS2 would lead to price rises for train tickets
  • 60% said they would not pay more to ride on HS2
  • Only 7% would be prepared to pay increased prices for the high speed line
  • 80% said they felt sympathy for people who may lose their homes to HS2, even though they may be compensated
  • A mere 11% of people thought the high speed rail link would actually benefit the majority of commuters

 

That was 7 years ago. Since then, it has even harder to build a case for HS2.

For many years, politicians insisted that HS2 was on time and within budget. Skeptics referred to the Elizabeth Line (previously Crossrail), which appeared to be “on time and on budget” until a few months before it was scheduled to begin. This all changed in a matter of months, with billions added to the Crossrail budget. Worse, the launch date was pushed out from December 2018 to possibly 2021 in the summer of 2018.

Now, according to the HS2 website, Phase One will open sometime between 2029 and 2033… so place your bets!

Spiralling costs

Transport Secretary Grant Shapps published the Stocktake document by incoming HS2 Ltd Chair Allen Cook at the start of the Parliamentary term. This confirmed what opponents Stop HS2 had long predicted: HS2’s expenses and schedule were woefully behind schedule.

Parliament had been told by ministers that the budget for HS2 was £55bn. However the cost for HS2 officially went from £55bn in 2015 prices to £81-£88bn in 2019 prices (£72-78bn in 2015 prices).

When a new high speed railway was first presented as an alternative to expanding Heathrow airport, the suggestions were that this would cost about £18billion. However when the HS2 proposal was firmed up and made public, Phases 1 and 2 were expected to cost £33billion in total, with Phase 1 opening in 2026 and Phase 2 in 2033. By 2013, this had risen to £42 billion, excluding the cost of the trains. A further review set the funding envelope for delivery of the full HS2 scheme of £55.7bn at 2015 prices.

The overall cost of completing HS2 has now ballooned from £33bn a decade ago to an estimated £100bn in 2023. That’s almost double the original quote, and significantly more than the £18bn posited at its first suggestion.

Bad for the environment

Despite their best efforts to dress HS2 up as an ecologically sound project, the environmental case for HS2 fails to hold water; the operation of HS2 will cause increasing carbon emissions, well into the 22nd century, in addition to any embedded carbon from construction. There will be negligible modal shift from cars and planes, there will be massive damage to the natural environment, including sensitive wildlife sites and HS2 Ltd’s mitigation efforts are failing.

Even when HS2 was first suggested, the carbon case was at most neutral, with the operation of HS2 potentially balancing the carbon cost of construction over decades. Yet, things have deteriorated substantially since then.

Building HS2 will result in embedded carbon emissions, which HS2 Ltd predicted in 2019 to be roughly 1,451,000 tCO2e tonnes.

However, as of February 2019, the carbon case massively worsened, with the latest figures from HS2 Ltd showing that after 120 years of operations, HS2 would be increasing carbon emissions rather than reducing them.

Habitat destruction

HS2 Ltd has not given a comprehensive list of wildlife locations that will be directly or indirectly impacted by HS2, however it is known to number in the hundreds.

An examination by the Independent on Sunday way back in 2013 discovered that Phases 1 and 2 had already affected over 350 sites: they reported: “Among the sites that could be directly damaged or indirectly affected are a national nature reserve, 10 county wildlife trust reserves, about 50 ancient woods, 30 river corridors, 24 Sites of Special Scientific Interest (SSSIs, the highest level of protection) and hundreds of other wildlife habitats. Among the rare or scarce species at risk are the small blue butterfly, long-eared owl, stag beetle, great crested newt, purple hairstreak butterfly and Bechstein’s bat.”

More recently than the IoS report, the Wildlife Trusts condemned the HS2 Phase 2b draft Environmental Statement saying: “HS2 Ltd’s own figures for the latest phase of the Phase 2b route show it will have a devastating impact on important places for wild plants and animals. 12 highly protected areas for nature conservation known as Sites of Special Scientific Interest, 111 Local Wildlife Sites and 19 ancient woodlands will be seriously damaged.

“HS2 Ltd’s work on this latest phase of the HS2 route is derisory in its assessment of the environmental impact. It is incomplete, there isn’t enough detail, there are significant omissions, it lacks sufficient proposals to compensate for nature’s loss, and to make matters even worse, there’s very little information about the impact on species. On the evidence, we have been given, this phase will result in an unacceptable level of damage to wildlife along the route.”

The Independent also reported on effects from the operation of HS2, saying “The toll on individual animals will be great. A Spanish study found that high-speed trains kill about 36 animals per kilometre. If that was applied to both phases of HS2, this would result in some 20,000 mammals, reptiles and amphibians being killed on the line every year.”

Even their best efforts are a blunder

Even where HS2 Ltd has attempted to prevent animal loss, it has failed to do so. Here are a few examples:

  • Trees planted in 2018 to replace destroyed woods were allowed to die, according to HS2, because watering them was too expensive.
  • To build a “biodiversity zone,” HS2 Ltd destroyed an existing County Wildlife Park.
  • Berkshire, Buckinghamshire, and Oxfordshire Wildlife Trust (BBOWT) barred HS2 contractors from entering Calvert Jubilee Nature Reserve because HS2 planned to destroy wildlife habitat before replacing it, leaving wildlife with nowhere to go in the meanwhile. Luckily BBOWT were there…

In summary

I always try to keep an open mind, but it’s impossible to remain neutral on a topic as divisive as HS2. It appears that in 2023 (13 years after HS2 was conceived), it is significantly easier to argue against HS2 than for it. How alarming then, that this fact doesn’t seem to make a jot of difference to the outcome. We’re getting it… whether we like it or not.

…Are we truly that powerless? In spite of widespread objection from the British public and multiple members of parliament, the project ploughs ahead; through fields, pastures, homes, gardens, habitats and nature reserves. Will it all be worth it? Or are we tearing our country and its economy to shreds?

EARTHQUAKES – A CONSTRUCTION PERSPECTIVE

On 6 February 2023, a Mw 7.8 earthquake struck Turkey and Syria. It was followed by a Mw 7.7 earthquake nine hours later, centred 95 km (59 mi) to the north–northeast from the first, in Kahramanmaraş Province. There was widespread damage and tens of thousands of fatalities.

It was the deadliest earthquake worldwide since the 2010 Haiti earthquake and fifth-deadliest earthquake of the 21st century. As of 21 February 2023, over 48,900 deaths have been confirmed; over 42,300 in Turkey, and over 6,600 in Syria… and building regulations aren’t being adhered to?? Buildingspecifier.com’s Joe Bradbury investigates:

Earthquakes cost lives. They also cost money. LOT’S of it. Collectively, the latest earthquakes across Turkey and Syria are estimated to have caused US$84.1 billion worth of damage, making them the fourth-costliest earthquakes on record. Coupled with that, it is also the deadliest natural disaster in Turkey’s modern history.

Whilst people are still being pulled from the rubble, the rest of the world watches, reeling – how did this happen and what could we have done to lessen the fatal outcome?

The sight of newly built apartments toppling during the carnage has stirred much heartbreak and outrage, especially within the global construction community. The fact that even some of the newest residential buildings in Turkey and Syria have crumbled to dust has raised serious concerns about current building safety regulations in those countries.

Afterall, buildings should be able to resist quakes of this magnitude thanks to modern construction techniques. And regulations enacted in the aftermath of prior tragedies in the country were supposed to ensure that these safeguards were in place.

Although the quakes were strong, experts within the field are now saying that well-built buildings should have been able to withstand them. So why did so many topple, taking thousands of people with them?

Speaking on the subject, Prof David Alexander, an expert in emergency planning and management at University College London recently told the BBC “In most places the level of shaking was less than the maximum, so we can conclude out of the thousands of buildings that collapsed, almost all of them don’t stand up to any reasonably expected earthquake construction code.”

Why aren’t building regulations being enforced?

Following earlier disasters, such as the 1999 earthquake that devastated the city of Izmit in Turkey’s northwestern region, construction restrictions have actually been strengthened. Yet, it is now coming to light that the legislation,(including the most recent requirements established in 2018) have thus far been poorly enforced.

In Turkey, for example, the government has offered periodic “building amnesties,” which are effectively legal exemptions from paying a charge for structures built without the necessary safety certificates. They have been in effect since the 1960s (with the latest in 2018).

Opponents have long cautioned that such amnesties increase the likelihood of disaster in the case of a severe earthquake. According to Pelin Pnar Giritliolu, Istanbul chairman of the Union of Chambers of Turkish Engineers and Architects’ Chamber of City Planners, up to 75,000 buildings in the devastated earthquake zone in southern Turkey have been granted construction amnesties.

We can do better

Thankfully, other countries take their responsibilities more seriously and stand as a shining example for the benefits of adhering to code. Japan is one such example; where millions of people live in densely populated high-rise buildings despite the country’s history of severe earthquakes. Japan alone demonstrates how construction codes can assist in keeping people safe during just such catastrophes.

Building safety criteria vary depending on a building’s usage and proximity to earthquake-prone areas: from simple reinforcing to motion dampers throughout the structure to installing the entire structure on top of a massive shock absorber to isolate it from ground movement.

The relationship between a building and an earthquake

We’ve built magnificent structures and cities throughout history, only for them to be destroyed by natural forces. Earthquakes are one of the most devastating forces on Earth; seismic waves travelling through the ground can demolish structures, kill people, and cost enormous sums of money in loss and repair.

According to the National Earthquake Information Centre, 20,000 earthquakes occur each year, with 16 of them being catastrophic disasters.

Engineers have introduced new designs and building materials over the last few decades to better equip structures to resist earthquakes.

Before delving into the characteristics of earthquake-proof buildings, it’s critical to understand how earthquakes affect man-made structures. When an earthquake happens, shockwaves are sent throughout the ground in brief, quick intervals that stretch in all directions. While structures are normally designed to withstand vertical forces caused by their weight and gravity, they are not designed to withstand side-to-side pressures caused by earthquakes.

This horizontal movement causes vibrations in the walls, floors, columns, beams, and connectors that keep them all together. The movement disparity between the bottom and top of structures causes enormous stress, causing the supporting frame to break and the entire structure to collapse.

How to construct earthquake-safe buildings

Engineers labour to reinforce the structure and counteract the forces of a probable earthquake when designing an earthquake-proof building. Because earthquakes generate energy that pulls buildings in one direction, the technique entails having the building push in the other direction. Here are several strategies for making structures more earthquake resistant.

  1. Lay moving foundations

The structure is built on flexible pads that insulate the foundation from the earth. When an earthquake strikes, just the foundation shifts, while the building retains its structural integrity.

  1. Use shock absorbers

Tuned dampers mounted to beams transform motion into heat and absorb stress by using pistons and oil. This is accomplished through the use of two methods – vibrational control devices and pendulum power.

  1. Strengthen the structure of the building

Buildings must disperse forces that go through them during a seismic event in order to withstand collapse. Shear walls, cross braces, diaphragms, and moment-resisting frames are essential for building reinforcement.

  1. Use earthquake-resistant materials

The different forms of structural steel allow it to bend without breaking. Wood is a lightweight and bendable material with a high weight-to-strength ratio. Contemporary materials have the ability to be more flexible and shape-retaining.

In summary

Earthquakes are a powerful, destructive, and unexpected force that may demolish buildings, destroy towns, and put construction companies’ labour to the test. Certain areas of the world are more vulnerable to earthquakes than others, and these cities, towns, communities, and urban centres must safeguard themselves and their citizens from these natural disasters.

Governments must follow and enforce building codes; failing to do so results in blood on their hands.

The most difficult aspect of preparing for earthquakes is that no one knows when one will occur or how large it will be. Current measurement and detection technology can assist us in being better prepared for them. Building-resistant material advancements have also improved the construction industry’s ability to build for earthquakes.

The construction industry is perfectly positioned to take use of current technology that has the potential to save both lives and cities.

10 construction innovations that have transformed the industry

It’s been around 2.5 million years since the Stone Age, when people lived in caves and used tools made of various sorts of stone. We have witnessed tremendous exploits in the realm of building innovation throughout the evolution of humanity – and possibly the highlights of the construction revolution have occurred within the last 40 years. Joe Bradbury of Buildingspecifier.com examines the top ten construction inventions of our time to reveal our outstanding technological heritage:

1. Mechanisation

To truly comprehend the revolutionary impact of mechanisation, we must go back a great deal further than 40 years.

The introduction of hydraulic and pneumatic devices in the mid to late nineteenth century was a truly astonishing innovation for our species, leading to the development of earth-moving equipment and other gear that are today standard in our business. These nineteenth-century technologies have greatly reduced the time and effort required for large-scale undertakings.

Fast forward to the early twentieth century, when mechanisation began to exhibit more advanced functioning and capacities. We introduced cherry pickers, concrete mixers, cranes, and power tools around this time. During this period, the internal-combustion engine appeared, replacing hand shovels, wheelbarrows, and working animals with forklifts, tractors, and bulldozers.

2. Prefabrication and Construction Industrialization

It can be challenging to assemble huge sophisticated components on-site, exposed to the elements, piece by piece. Off-site fabrication has significantly boosted the efficiency of this process.

A huge heat exchanger built in a vendor’s shop, for example, will not only arrive on site ready to plug in, but will also benefit from better management of components and material inventories, as well as increased efficiency and production. The return on investment rises, while waste and inefficiency decrease.

When components such as concrete insulated panels, timber frame panels, pump units, compressors, and instrument panels are manufactured in a factory rather than on-site, significant time savings are realised.

3. Computer-Aided Design (CAD) (CAD)

During the height of the Middle Ages, architects, draughtsmen, master stonemasons, and builders produced some of the world’s most stunning buildings employing ground-breaking design and construction technologies.

These approaches remained mostly unaltered for several centuries. However, in the latter half of the twentieth century, computer-aided design (CAD) appeared, permanently altering construction – for the first time, disagreements during the design process were rendered evident.

Previously, issues such as separate systems, electrical conduits and high-voltage alternating current ducting for example, competing for the same physical space bedevilled architects and builders, with their two-dimensional plans and section drawings.

4. Building Information Modelling (BIM)

While computer-aided design (CAD) revolutionised the role of designers, Building Information Modelling (BIM) has proven to be astonishingly versatile, allowing architects, engineers, contractors, and subcontractors to collaborate on the fine details of design and construction by using the same database and computer model.

All project stakeholders collaborate on a detailed 3D model that incorporates all of a structure’s functional systems – such as pavement or curbs, beams and girders, HVAC and electrical installations, as well as the aesthetics of walls, arches, roofs, and railings.

Because BIM is a collaborative process from start to finish, it enables all preconstruction partners to visualise and analyse design decisions, as well as identify interferences and other problems, before work begins on site.

Working cooperatively saves contractors countless resources because building does not begin until all parties have submitted their plans, guaranteeing disputes are found and corrected quickly, easily, and ahead of the ground being broken on site.

5. Mobile Devices

In various different ways, mobile technology has drastically altered the construction sector. One of the most significant for contractors is the improvement in project management. All parties involved can collaborate utilising the same consolidated information sources via smartphones and tablets, ensuring that no one is left out of the loop, no matter where they are.

Real-time analytics in construction have also been made possible by mobile devices. Instead of needing to write a report at the end of the day, foremen may now keep track of performance, conditions, and costs throughout the day utilising reporting tools. Project managers can use mobile business information to predict necessary modifications, allowing them to respond immediately to keep things on track and within budget. Plus, reporting apps ensure that all stakeholders have access.

6. Robotic Total Stations

Traditionally, a team uses building drawings plus a tape measure, spirit level, and theodolite – a precision equipment for calculating angles – to find attachment sites for things like cable trays and pipework.

This approach, however, does not function well with more complex structures. It is time-consuming and labour-intensive, with a large margin for error that can result in major implications such as confrontations with other construction services and prefabricated systems that do not fit, wasting time, money, and materials.

Enter the Robotic Total Station (RTS), an electronic theodolite with an electronic distance measurement that can be controlled remotely from a distance. The layout can be accomplished by a single person using a tablet equipped with the necessary software, with RTS ensuring higher efficiency, improved accuracy, fewer mistakes, and less paperwork, as well as lower labour expenses.

7. Eco-Friendly Building Materials

As the construction sector seeks ways to cut carbon emissions, it is turning to more sustainable building methods. This includes the use of environmentally friendly building materials such as Cross-Laminated Timber, salvaged wood, bamboo, recycled rubber, and a variety of other novel materials. Consider a construction made of straw bales, rammed earth, Hempcrete (a concrete-like substance manufactured from hemp), or ferrock (concrete-like material made from steel dust); some of these materials absorb and trap carbon dioxide, indicating that they are carbon-neutral.

Using sustainable building materials benefits the environment while also lowering construction costs, improving structural energy efficiency, and increasing property value. The reduction in operational costs reduces overall building costs by 5 to 15%, depending on the green material utilised. In some locations, there are also regulatory incentives that make sustainable building more appealing.

Buildings that are created in a sustainable manner are in high demand. They frequently have higher occupancy rates and rental prices than traditional-built structures. Green construction materials may also benefit occupant health. Green construction is a win-win-win situation for the industry, the residents, and the earth.

8. Personal Protective Equipment (PPE)

While personal protective equipment (PPE) is significantly less technologically advanced than the other items on this list, there is no doubt that it has helped to revolutionise the construction industry in terms of health and safety during the previous 40 years.

Protective apparel has gradually evolved as the hazards encountered by construction workers have increased.

For decades, the high-vis jacket and hard hat have been the cornerstones of construction site safety apparel. This will remain the case, but new technologies are on the horizon that will expand the capabilities of protective garments to provide better safety and extra services to their users going forward.

9. Cloud Computing

Cloud computing is at the heart of the digital construction revolution. Prior to cloud computing, project data was constrained by hardware constraints. You may now outsource data processing and storage to powerful devices that are available from anywhere. As a result, there is nearly limitless storage and a totally connected workplace.

Real-time data is made available to all stakeholders by leveraging the power of cloud computing, allowing for easy sharing and collaboration. The team is no longer dependent on time-consuming in-person status checks and device storage capabilities.

For contractors, storing project data in the cloud is a no-brainer. According to a survey conducted by the Associated General Contractors of America in partnership with Sage Construction and Real Estate, 85% of contractors have implemented or planned to implement cloud solutions. Cloud computing not only simplifies data storage and access, but it also safeguards you against data loss, damage, or theft. Secure cloud storage protects data while increasing team accessibility.

10. Digital Twins and As-Builts

Despite the fact that the phrase “digital twins” was coined in 2002, the notion of digital twins and digital as-builts has been in use for decades. NASA was among the first to employ a variant of the technique in the 1960s. To avert additional calamity, engineers tried solutions on a digital duplicate of Apollo 13.

As project teams move away from manual, time-consuming paperwork, the usage of digital twins is expanding in the construction sector. A digital twin, also known as a digital as-built, is a virtual counterpart of a physical object that provides real-time data throughout the development and maintenance processes. These computer representations can be used to anticipate carbon footprints, simulate situations, and collect real-time data via sensors installed in the environment.

Attention! The construction industry needs you

It’s no secret that the construction industry is experiencing a severe skills shortage. The business has long been plagued by a scarcity of experienced labour, making meeting deadlines more challenging than ever. Now, according to a new study, more than a third of students have ruled out a future in construction. What’s happening and how can we overcome it? Buildingspecifier.com’s Joe Bradbury discusses:

I’d like to start by stating that I do not intent for this piece to exude negativity, for I have faith in the hardworking professionals and unsung heroes of construction; they have already achieved so much in changing things for the better throughout the course of the last decade, and I remain hopeful that things are moving in the right direction…

…however, there’s no easy way to put this – alarmingly, according to a poll of nearly 4,000 adults over the age of 16 who are currently enrolled in high school, college, or university, 37% would never consider working in the construction sector.

In fact, students were also revealed to more critical of construction when asked their opinions on 17 different industries. Almost half of female respondents claimed they would not work in construction.

Only 5% of the students asked were actively contemplating professions in the industry, compared to 38% of those seeking careers in professional, scientific, and technical activities.

This saddens me after years of keeping my eyes professionally on the wide sprawling and richly varied construction industry. I have seen such vision, such innovation and enthusiasm. I have felt an express desire to deliver the built environment that is deserved and to be proud of. For me, the sector is teaming with inspiration, and if this is failing to be picked up by the next generation, I feel this must be due to a failure to present and communicate ourselves as an industry. We have the goods, we just need to get it across.

Only then, can we attract the type of budding talent that can evoke change.

Nevertheless, the results of the study, conducted by data specialist Savanta ComRes and published by consultancy WSP, should not be ignored.

How can we improve our situation?

Discussing the results of the study, WSP executive director Rachel Skinner stated, “We can’t keep doing things the same way we always have if we want to successfully address the various elements of the critical climate crisis.”

“Having the necessary skills in sufficient strength, breadth, and depth is critical if the UK is to capitalise on the chance to improve economic growth and build new knowledge through the climate transition.”

The research showed that this could be an “uphill struggle”, she said, adding: “While today’s students have grasped the crucial importance of the engineering and infrastructure sectors in securing a lower-carbon future, many of them do not view these sectors as prime targets for their own future employment.

“This leads to key questions: how can we change this perspective? What more can we do to accelerate the development of a workforce with the right skills to deliver against the UK’s net-zero commitments?”

Only half of the students polled believed their generation could have a significant impact on environmental and climate change challenges, and fewer than two in five were confident in their comprehension of the term “green jobs.” And therein lies the rub.

According to two recent surveys, the industry’s skills shortfall has reached “alarming proportions,” with 75% of civil engineering firms finding it difficult to attract experienced employees and 96% of supply chain companies grappling with net-zero capabilities.

The Office for National Statistics revealed also that there were 49,000 unfilled construction job vacancies in September alone.

Coupled with this, the average age of the construction workforce is presently 50-56, with an increase in early retirement seen since the beginning of 2020. This adds a sense of urgency to the problem, gradually increasing the skills shortage into a pending crisis.

We need more people, people!

According to a report by the Construction Skills Network (CSN), the construction industry would require almost a quarter-million additional workers by 2026 to meet the expanding demands in the UK building sector. Many employees have departed the UK as a result of Brexit, and some businesses have been downsizing throughout the pandemic. As a result, many construction firms are now experiencing a skilled labour shortage, which will disproportionately effect private housing, infrastructure, repair, and maintenance.

What can we do about it?

If we want to grow our businesses and bridge the skills gap, there are several things we can do to increase our chances of attracting and retaining high-quality employees going forward.

Provide opportunities for advancement in jobs

Young people want a future. So it’s critical to provide advancement opportunities in the roles we advertise, and to clearly express to prospective applicants how they may push themselves and climb the ladder within the industry. When you have great employees, it is critical to allow them to go into other positions and make your company the place where they want to advance their careers. This can mean the difference between employees leaving after a short amount of time and employees staying with the company for many years.

This is not only good for employee morale, but it also means that we will be able to keep personnel long enough to reap the benefits of their experience indefinitely. This will result in a workforce that is knowledgeable, experienced, and talented, allowing the industry to flourish into the future and contribute to its reputation. By promoting talented employees, we will be able to reduce the number of employees we have to hire from outside sources, lowering expenses and time spent.

Look after the workforce

While we obviously want to prioritise projects, deadlines, and profits, it’s equally critical to keep employees happy and satisfied at work. Once you’ve recruited exceptional people to your firm, it’s critical to assist them enjoy their roles while also allowing them to advance, so they may thrive and produce the best results for your organisation. Workers want to feel respected and heard at work, therefore establishing a strong line of command in management is critical. It also serves as a welcoming and warm face for new employees, allowing them to get up and running right away.

When things get hectic and deadlines approach, remember to take the time to listen to your employees’ suggestions and recognise their accomplishments. Employee of the Month programmes and mentions in company newsletters are excellent ways to reward employees and make them feel valued and appreciated for their efforts. Smaller things like company socials and celebrating staff birthdays or work anniversaries are also great extra touches to make every worker feel appreciated and welcome.

Widen the search

Try broadening your recruitment process by speaking at schools and colleges about available placements and programs. Some students might not think about taking on a career in construction due to the lack of representation, so some encouragement and information can be all they need to get interested. Sending a diverse representation from your company into these establishments can immediately make a difference too, and this might encourage applications to your company from young people of a variety of backgrounds.

In summary

If the building sector is to provide three million new social homes over the next 20 years to address the housing crisis and address the 11,000+ homes throughout the UK that have been empty for 10 years or more, it must have a dedicated and capable workforce.

Ultimately, the best way to attract new talent so sorely needed by the industry today is to make sure the construction industry is a positive place to be. Ergo: If you build it, they will come!
