Insights from New Data on Australian Construction

Construction Industry Survey 2024

 

The ABS has published detailed data on the Construction industry for 2023-24. Although released as part of the Australian Industry data, this is the seventh of a series of irregular and infrequent Construction Industry Surveys done by the ABS [1]. The ABS collected employment, wages and salaries, income, expenses, operating profit, earnings before interest tax depreciation and amortisation (EBITDA), and industry value added (IVA) for private sector construction businesses. 

 

Construction is an industry division, divided into three subdivisions: 

·      Subdivision 30 Building construction, with the two groups of Residential and Non-residential building;

·      Subdivision 31 Heavy and civil engineering construction; and

·      Subdivision 32 Construction services with five groups of Land development and site preparation services, Building structure services, Building installation services, Building completion services, and Other construction services.

 

The survey divides income by: 

·      Type of client;

·      Nature of contract (contracting, subcontracting or speculative);

·      Type of asset (houses, other residential building, non-residential building, road and bridge construction, and other non-building construction); and

·      Type of work (new construction work, alterations, additions, renovations and improvements, and repairs and maintenance).

 

This post first looks at industry totals and the Construction subdivisions and groups, and details income and expenses. It then compares the amount per employee for income, wages and salaries, EBITDA and IVA across the subdivisions and groups to show their relative performance. The data on capital expenditure, work done by type of asset and type of work is presented. 

 

Australia is in the fortunate position of having one of the world’s best statistical agencies with the ABS, at a time when other countries are having issues with their data collections [2].

 

 

 Industry Totals

 

Total employment was 1,291,000 people, of which Construction services were 883,000 or 68%. Within Construction services, the largest groups were Building installation services (329,000 people) and Building completion services (223,000 people). Building construction employed 254,000 with 173,00 in Residential building, and Heavy and civil engineering construction employed 154,000. 

 

Total income includes income from non-construction services and sales of land and goods, but the survey also has income from contracting and subcontracting. Construction total income was $633.6 billion with $438.6bn from contracting and subcontracting (69%), with $77bn of contracting income from the public sector (17.5%). For the three subdivisions:

·      Building construction’s total income was $235.2bn, with $130.8bn from contracting and $21.5bn from subcontracting, contributing $152.3bn. 

·      Heavy and civil engineering construction’s total income was $122.4bn with $85bn from contracting, of which $47.2bn (55.5%) was for the public sector, and $13.2 from subcontracting, contributing $98.2bn. 

·      Construction services’ total income was $276.1bn, with $116.6bn from subcontracting and $71.4bn from contracting, contributing $188bn. 

·      Within Construction services, Building installation services was the largest group by income ($94.2bn), followed by Building completion services ($53.2bn), which together were 53% of Construction services income.

Figure 1. Contracting income by client type

 

 

Non-construction income was 31% of total income, with $113.2bn from the sale of goods and $61.2bn from services. Income from sales of land and goods was a high proportion of contracting and subcontracting income for Residential building (67%) and Land development and site preparation services (53%). Income from Non-construction services (including professional, scientific and technical services) was a high proportion of contracting and subcontracting income for Heavy and civil engineering (14%), for Land development and site preparation services (43%), and for Building installation services (18%). 

 

Figure 2. Non-construction income by source

 

 

Expenses were $570.7bn in 2023-24. The largest were purchases of goods and materials ($255.4b) and selected labour costs ($105.7b). Payments to other businesses for construction services, building and industrial cleaning services was $91.6b, and this will have included Professional services like architectural, engineering and surveying services, and rental and hire of machinery and equipment .

 

Purchases of land for property development was $12.2 bn, with Residential building accounting for $7bn and Land development and site preparation $3bn of the total. Those purchases incurred $2.1bn and $1.3bn in interest costs for the groups, which also had $762mn and $1.4bn in depreciation and amortisation expenses. 

 

Performance Per Employee

 

Comparing the amount per employee for income, wages and salaries, EBITDA and IVA highlights the differences between the industry subdivisions and groups. The Non-residential building and Heavy and civil engineering construction subdivisions had much higher average wages and salaries and income than the rest of the industry, and the highest IVA per employee. The highest operating profit per employee and EBITDA was in Land development and site preparation, which was also the group with the highest income from non-construction services, and Building installation services had the lowest operating profit per employee and EBITDA.

Note: W & S is Wages and salaries, Total income includes income from non-construction services and sale of land and goods, Profit is Operating profit before tax, EBITDA is Earnings before interest tax depreciation and amortisation, IVA is Industry value added. 

 

The figures below show the differences between the groups for wages, profits, EBITDA and IVA per employee. The general pattern is that Construction services have lower values than Building and Engineering, often around half as much, particularly for wages and contracting income. Average wages are notably low for Residential building and Building completion services. Contracting income per employee is highest in Non-residential building, by a considerable margin over Residential building and Engineering, and the three groups of Building installation, Building completion and Other construction services have almost the same contracting income per employee.

 

Figure 3. Wages and salaries per employee

 

 

Figure 4. Income per employee

 

Note: Includes contracting and subcontracting income, excludes non-construction income from sales of land and goods.

 

For EBITDA and IVA where non-construction services income is included, Land development and site preparation had the highest EBITDA and third highest IVA per employee. Residential building had lower IVA per employee but higher EBITDA than both Non-residential building and Engineering, which were the two groups with the highest IVA per employee. Interestingly, there is only a weak relationship between EBITDA and IVA per employee across the industry groups. 

 

Figure 5. EBITDA per employee

 

Note: EBITDA is Earnings before interest tax depreciation and amortisation.

 

The four Construction services groups of Building structure services, Building installation services, Building completion services and Other construction services have IVA per employee values around half that of Engineering, and around two thirds of Building.

Note: IVA is Industry value added.

 

Capital Formation

 

There is a well-established relationship between the amount of capital (both physical and intellectual) available for each worker and their level of productivity. All else equal, the more capital the higher the productivity. The survey has capital expenditure (capex) and gross fixed capital formation (GFCF) for the eight industry groups, and Figure 5 shows  the relationship between IVA per employee, capex and GFCF per employee.

 

Land development and site preparation had the highest level for both capex and GFCF per employee indicators, due to including purchases of land and equipment. Similarly, Engineering has a high capex that includes purchases of machinery and equipment, and also the highest IVA per employee. Capex is low for Residential and Non-residential building  because of the low level of ownership of heavy equipment and machinery due to extensive use of hiring and leasing, however that equipment and machinery lifts the level of IVA per employee. The other four trades in Construction services have capex and GFCF tracking IVA per employee, and are the best example of the relationship between capital and productivity.

Work Done by Type of Asset and Type of Work

 

Building Construction and Construction Services Income

 

There is a new set of data in this year’s survey that has the income from different types of asset built, divided into houses, other residential building and non-residential building, and the type of work done, divided into new construction work, alterations, additions, renovations and improvements, and repairs and maintenance. This is given for the three Building groups of Residential and Non-residential building and Construction services. 

 

Table 3. Income from construction services by type of work

 

 

Residential projects provided the largest source of income for Construction services, with $55.6bn from House construction and $17bn from Other residential building, a total of $72.6bn, compared to Construction services’ Non-residential building income of $66.2bn and Non-building construction’s $49.3bn. For the Non-residential building group, Alterations etc. income of $18bn was 58% of income from New work of $31bn.

 

Table 4. Type of work done by Building construction and Construction services

 

 

The distribution of income across type of work and type of asset can be found from this data. This has not previously been available and it allows a comparison of the relative importance of type of building work done. New work is 72% of the total, but of particular interest is that 9% is repair and maintenance, which is generally inefficient and labour intensive compared to new work. Around three quarters of R&M is (unsurprisingly) done by trades in Construction services and, except for Non-residential building, most of the alterations and additions.

 

Engineering Construction Income

 

Heavy and civil engineering construction total income was $98.2bn, of which $85.1bn was from contracting. Income was broken down by project type and into New work and Improvements and Repairs and maintenance (R&M): 

·       Road and bridge construction ($37.5bn; New work $34.5bn, R&M $2.6bn );

·       Railways, tramways and harbour construction ($17.3bn; New work $17bn);

·       Water storage and supply, sewerage and drainage construction ($7.2bn; New work $6.1bn, R&M $1.1bn);

·       Electricity generation, transmission and distribution construction ($11.5bn; New work $11.1bn);

·       Telecommunications construction ($1.2bn; New work $$567mn, R&M $595mn);

·       Oil, gas, coal, pipelines (not water) and other heavy industry construction ($9.4bn; New work $7.2bn, R&M $2.2bn);

·       Other non-building construction ($8.2bn; New work $7.6bn);

·       Building construction ($5.1bn; New work $5.5bn, Alterations & additions plus R&M $593mn). 

 

Roads and railways are by far the largest categories of new engineering work ($37.5bn and $17.3bn respectively), and it should be noted that 2023-24 was a year with exceptionally high public expenditure on infrastructure, with major projects underway in NSW, Victoria and Queensland. The third highest category was Electricity generation, transmission and distribution construction, reflecting expenditure on the energy transition with $11.1bn of new work. Repair and maintenance was 8.3% of total Engineering income. 

 

 

Key Points

 

Total income included income from non-construction services and sales of land and goods as well as income from contracting and subcontracting. Construction total income was $633.6 billion with$438.6bn or 69% from contracting and subcontracting. Contracting income from the public sector was $77bn. Sales of land and goods was a high proportion of contracting and subcontracting income for Residential building (67%) and Land development and site preparation services (53%).

 

Construction services have lower wages, profits, earnings before interest, tax, depreciation and amortisation (EBITDA) and industry value added (IVA) per employee values than the Building and Engineering groups, particularly for wages and contracting income. Contracting income per employee is highest in Non-residential building, much more than Residential building and Engineering, and the three groups of Building installation, Building completion and Other construction services have almost the same contracting income per employee. 

 

When non-construction services income is included, Land development and site preparation had the highest EBITDA and third highest IVA per employee. Residential building had lower IVA per employee but higher EBITDA than both Non-residential building and Engineering, which were the two groups with the highest IVA per employee. There is only a weak relationship between EBITDA and IVA per employee across the industry groups. The four Construction services groups of Building structure services, Building installation services, Building completion services and Other construction services have IVA per employee values around half that of Engineering, and around two thirds of Building. 

 

The survey has capital expenditure and gross fixed capital formation (GFCF). Land development and site preparation had the highest and Engineering the second highest for capex and GFCF per employee, due to purchases of land and equipment. Capex is low for Residential and Non-residential building  because of hiring and leasing of heavy equipment and machinery. The other four trades in Construction services have capex and GFCF closely tracking IVA per employee, a good example of the relationship between physical capital and productivity.

 

Data on the distribution of income across type of work and type of asset has not previously been available. For Building construction New work is 72% of the total, alteration, additions and improvements 19%, and repair and maintenance is 9%, with around three quarters of R&M done by trades in Construction services. However, the data does not include the number of people employed in R&M. 

 

For Heavy and civil engineering, total income was $98.2bn, of which $85.1bn was from contracting. Roads and railways are by far the largest categories of new work ($37.5bn and $17.3bn respectively). 2023-24 was a year with high public expenditure on infrastructure and 55.5% of income came from the public sector. Repair and maintenance was 8.3% of total Engineering income. 

 

The 2023-24 Construction Industry Survey has provided a level of detail previously unavailable. Key insights are that 69% of total income is from contracting and subcontracting, with the rest from provision of services and sale of land and goods, and 9% of income is from repair and maintenance. Although only 18% of total contracting income is from the public sector, for Engineering it is 56%. Purchases of land by Residential building was $7bn and by Land development and site preparation $3bn, with $2.1bn and $1.3bn in interest costs respectively. In Non-residential building work, Alterations, additions, renovations and improvements income of $21.2bn was 41.2% of the income from New work of $51.3bn. For House construction by Construction services, income from New work was $30.6bn, and for Alterations etc. was $17.6bn, 57% of New work income. 

 

Non-residential building and Engineering had the highest IVA per employee, followed by Land development and site preparation and Residential building. There is a wide productivity differential across the industry groups, as measured by IVA per employee. That may be an imprecise measure, but it is indicative of the labour intensity of the trades, and the higher capital intensity of the Building and Engineering subdivisions. One way to improve overall industry productivity would be through lifting the capital intensity of Construction services by providing incentives for them to increase capex. 

 

Conclusion

 

The ABS 2023-24 Australian Industry data included a survey of the Construction industry, with previously unavailable data on income from work done and type of work, clients and other variables at the level of eight industry groups. Therefore, this data has much more detail compared to the three industry subdivisions of Building, Engineering and Construction services used in regular ABS publications, because subdivisions are made up of industry groups.  

 

The first three groups are Residential building, Non-residential building and Heavy and civil engineering, and there are five groups of Construction services: Land development and site preparation services, Building structure services, Building installation services, Building completion services, and Other construction services.

 

In terms of policy and industry development, this detailed data is important because it clearly shows the differences in the characteristics of the industry groups, their clients and sources of income. It will also allow recalculation of construction labour productivity for the different types of work done. 

 

Construction is better viewed as three sub-industries when the differences between Residential building, Non-residential building and Engineering construction are taken into account. These structural differences affect the way clients, contractors, subcontractors, designers and suppliers work and interact, and these ABS subdivisions have their own characteristics and ways of working. For example, house builders have pattern books, commercial building uses architects, and infrastructure is designed by engineers.

 

Industry policies that target Construction will be challenged by sub-industries with limited, though important, similarities, and are unlikely to be relevant across them. The specific nature of the individual subdivisions often makes recommendations and policy directed at Construction as a single industry hard to implement or ineffective, separate policies are required.

The UK Office of National Statistics published a wrong CPI figure in April 2025 and 

a Systemic Review of ONS Economic Statistics noted  ‘there are widely recognised problems with the Labour Force Survey’ and  ‘resource pressures on economic statistics and on the ONS as a whole have intensified in the last two years.’ In 2014 issues with UK construction data were so serious they led to Construction Output being de-designated as a National Statistic. 

 

 

 

The Changing Composition of Construction Employment

 Data from Australia and the United States

 

 

One of the curious things about the construction industry is the perception of it as inefficient and technologically backward, yet it has been at the forefront of many scientific and technical advance for centuries. From Gothic cathedrals to railways and airport terminals, building and construction projects have bought together the best available resources to create increasingly complex structures using the best available technology. Demand for new types of structures with greatly improved capabilities in strength and span drove the development of the modern industry during the first industrial revolution in the nineteenth century. To buildiron-framed and steel-reinforced concrete buildings the industry had to not only master the use of these new materials but also develop the processes and project management skills the new technology required, with the roles of engineers, architects, quantity surveyors, contractors, subcontractors and suppliers becoming defined by the beginning of the twentieth century. The issue then, like today, was not the availability of jobs but the quality of skills during the adoption of new technologies by the industry. 

 

The industry has an undeserved reputation as a technological laggard and for low skilled workers. In reality, the nature of the work attracts people with technical skills who use ‘technological thinking’ to find solutions to the problems a project will encounter between inception and delivery. Technological thinking is essentially problem-solving through trial and error. Regardless of which part of construction they work in, for the vast majority of these people there is a great deal of satisfaction in doing this work well, following relevant codes of practice and meeting the required standards.

 

This post looks at data on construction employment, qualifications and occupations in the Australian and United States industries. It is not a comparison, because the data is not the same, but an attempt to relate changes in the composition of the workforce to changes in the industry, such as the volume and nature of work and the types of projects. Given the data, this analysis can only be indicative and the conclusions tentative. However, there is good evidence that the industry is neither a technological laggard nor an industry with an unqualified and low skilled workforce, and that these are common misperceptions and misrepresentations of construction. 

 

 

Australian Construction Employment Trends

 

Employment in the Australian industry has grown strongly over the last couple of decades, from 664,993 people in November 2000 to 994,283 in November 2010 to 1,363,057 in November 2024 [1], and over that period there has been both stability and change in the composition of the workforce. The percentage share of Technicians and trades has been and is around 50% of the workforce, similarly Labourers have accounted for 16-17% since 2000. During the mining boom the share of Machinery operators and drivers rose to 9% in 2012, but had fallen to 6% by 2024, the lowest share since 2000. As Figure 1 shows, the combined share of these onsite workers rose from 75% in 2000 to 77% in 2012, and was 73% in 2024. 

 

Figure 1. Australian construction workforce composition

 

Source: ABS 6291 Employed persons by Industry division and Occupation.

 

 

It is in the other occupations that the major changes have been happening, and here the trends have been long-running and gradual. The share of Clerical and administrative workers has steadily declined from 12.5% in 2000 to 8.5% in 2024, falling by a third over that time. The share of professionals was 2% in 2000, 4% in 2012 and 6% in 2024. And the share of Managers has increased from 9% in 2000 to 12% in 2016, where it has been since. As Figure 2 shows, the increase in the share of professionals has been the most significant change in workforce composition.

 

Figure 2. Australian construction workforce composition

Putting the numbers of people employed in different occupations adds some perspective. This data does not go back past 2023 because of the introduction of a revised classification system for occupations, however over the relatively short period between August 2023 and November 2024 there were some significant changes. In particular, the number of Professionals increased from 61,900 to 81,100, a dramatic change, and the number of Community and personal service workers went from 1,100 to 3,200. The number of Managers and labourers also increased, but Clerical and Sales worker numbers both fell, as did the number of Machinery operators.

Finally, another Australian Bureau of Statistics publication has qualifications and work by industry, and table 2 shows that two thirds of construction workers have gained a qualification after leaving school, and 14% have a bachelor degree or higher. 

 

Table 2. Construction workers by level of qualification

Source: ABS Education and Work, May 2024. 

 

The Australian Computer Society’s 2024 Digital Pulse report found Construction employed 12,512 technology workers (in information technology and telecommunications jobs), with 4,983 in management and operations, 2,970 in technical and professional, and 4,559 in ICT trades. That does not include the technology workers employed by the architecture, engineering and project management firms in the Professional, Scientific and technical services industry (possibly 10% of a total of 138,058 outside Computer system design and services).

 

United States Construction Employment Trends

 

In the U.S. the data is organised differently, and there are no qualifications by industry data available. There have been significant changes in the composition of the construction workforce, particularly in the last few years. For most years from 2000 to 2009 the Nonproduction employees share of total employment was between 22 and 23%, then from 2009 to mid-2017 it was 24% before rising to 25% at the end of 2017. In 2020 the share rose again to 26% and by 2024 was up to 27.5%. The number of Nonproduction employees in December 2000 was 1,503,000 and almost the same in 2014 at 1,553,000. From 2015 the number began increasing, to 1,903,000 in 2020 and 2,069,000 in 2022, and reached 2,284,000 in 2024 [2].

Another series from the U.S. has a similar pattern, for the number of Managers employed in Construction in January. Employment of Managers was 335,000 in 2000 and 414,000 in 2013, before it started increasing and almost doubled, going from 428,000 in 2014 to 785,000 in 2024. Because this was a much larger increase than the increase in Nonproduction employees over that period, the share of Managers in Nonproduction employees went from 22% in 2020 to 26% in 2013 to 32% in 2022, and was 34% in2024 [3].

 

Figure 4. Number of managers employed in U.S. construction

 

Source: U.S. Bureau of Labor Statistics, Employed full time: Wage and salary workers: Construction managers occupations: 16 years and over, retrieved from FRED, Federal Reserve Bank of St. Louis.

 

These trends in U.S. construction employment suggest a change in the industry around 2014-15. Total construction spending was recovering from the downturn after the recession in 2008-09, when monthly spending fell below $800 million, and was back to $1 billion in 2014. By 2020 the monthly spend was up to $1.5 billion. By historical standards this was a solid recovery but not exceptional. However, between 2020 and 2024 the total spend went up to $2.15 billion, driven by a doubling of manufacturing construction to $236 million a month as a result of the Biden Administration’s industrial policies that provided subsidies to build semiconductor fabs, data centres, grid infrastructure and renewable energy sites. 

 

With that increase in manufacturing construction, the number of Nonproduction employees and construction Managers also increased. The timing of this cannot be a coincidence, and could be attributed to the complexity and scale of the chip fabs, data centres and other computer and energy projects underway due the subsidies provided by the Biden Administration. Further, the change in employment was a break in the existing trend of gradually increasing employment of Nonproduction employees and construction Managers. The inflection point was 2021.

The U.S. Bureau Of labour Statistics has detailed occupational data for 2023, but unfortunately this is not available for earlier surveys so a comparison cannot be made. However, the 2023 data is useful because it has the number employed in construction in managerial, supervisory or technical support occupations across the industry divisions of trades, non-residential and residential building, and engineering. These total 1,030,370 people, or 13% of total construction employment in 2023 of 8,120,000, which would the other half of Nonproduction employees that are not cost estimators or doing other clerical and administrative work. Many of these employees can be assumed to have a bachelor degree, for example it is a requirement for construction and architectural managers. 

 

As Table 3 shows, the great majority are employed as trades supervisors (609,580) and construction managers (266,140). The third largest category is architecture and engineering (103,940). The fourth is computer occupations (22,080), and fifth OH&S (19,600). The others are compliance officers (5,660) and architectural managers (3,370).

Trades requiring qualifications like equipment operators (321,730), electricians (558,750), plumbers (384,870) and building inspectors (13,550) employed another 1,278,900 people. Adding these trade workers to the 1,030,370 managers and professionals above gives 2,309,270 and 28% of total construction employment in 2023 of 8,120,000. There were another 2,475,690 people employed in construction trades in 2023 as bricklayers, plasterers, painters etc., and many but not all of these workers would also have a certificate or diploma qualification. When the three groups are combined, this is over half the total number of employees. The BLS number of unqualified and unskilled workers was small, there were 858,900 laborers and 174,200 construction trades helpers.

 

Change Drivers

 

What can account for these changes in the composition construction employment in Australia and the U.S.? There are three reasons that are widely agreed on. The first is increased regulation, compliance and planning leading to more people spending more time to meet those requirements. In the U.S. there is the National Environmental Policy Act (NEPA), federal environmental legislation requires agencies to produce an environmental impact statement (EIS) before the project can start. These statements can be thousands of pages long and take years to prepare, and NEPA is a frequent target of criticism and reform efforts [4]. Some stats from a Thomas Hochman post on NEPA in December:

• Average environmental impact statement preparation time is 4.2 years as of 2022 
• Average review time grew from 3.4 years in 2008 to 4+ years by 2015, increasing by an average of 37 days per year
• Average delay from environmental review publication to resolution of legal challenge: 4.2 years
• Even a "finding of no significant impact" can take extensive time and documentation (1,200+ pages in one case)
• Up to $400 million spent just on regulatory/environmental review process for major projects
• Solar projects: 64% litigation rate
• 72% of NEPA litigation initiated by NGOs

 

In Australia planning rules are highly prescriptive and complex, with zoning, other regulations, and lengthy development approval processes reducing the ability of housing markets to respond to demand. Research on apartment prices in 2020 and house prices in 2018 by the Reserve bank found planning and zoning restrictions raised prices by up to 70%. A 2021 survey by Infrastructure Australia found: ‘Contractors and investors viewed planning and environmental approval processes as an unpredictable risk to project timelines and a driver of delay. The need to coordinate across multiple layers of government to obtain approvals, and the requirement to meet increasingly onerous conditions attached to many approvals, (e.g. in relation environmental approvals) prompted concern over delivery times’ (p.44). 

 

A second reason is the digitisation of construction and use of BIM leading to increasing offsite employment and project planning. A 2023 Brookings Institute report found only 23% of U.S. jobs were ‘low digitalisation’ in 2020 compared to 52% in 2003. From 2002 to 2010 the share of occupations with a high digitalization level doubled, from 9% to 18%, and in 2020 rose to 26%. A 2021 report by RMIT University found that 87% of jobs in Australia require digital literacy skills, and the 2024 submission by Industry Skills Australia to the Commonwealth Government’s Inquiry into the Digital Transformation of Workplaces (available here with all the other submissions) predicted only 45% of construction jobs would not be impacted by digital technology by 2030.

 

And a similar argument has increasing offsite manufacturing reducing the number of workers onsite and raising the proportion of offsite workers. The actual extent of the effect is unknown, but is likely to be marginal as the point is not replacing workers but moving them offsite, and there is still substantial site preparation and assembly work involved. Offsite manufacturing also requires detailed digital design and production planning work. 

 

Conclusion

 

The construction industry is neither a technological laggard nor an industry with an unqualified and low skilled workforce. These are common misperceptions that probably are often the result of people seeing poorly organised and managed sites, which could be addressed through better site facilities and maintenance. In fact, the industry employs a wide range of skills and requires technical competence from the majority of its workers. In Australia, two thirds of the workforce have a post-school qualification, and in the U.S. it is over half. In both countries the share of unskilled labourers is small, at around 10% of the workforce [5]. 

 

There are other interesting parallels between Australia and the U.S. In Australia, the share of professionals rose from 2% in 2000 to 6% in 2024, and the share of Managers increased from 9% in 2000 to 12%. Adding the 2024 8% share of Clerical and administrative workers makes 26% in these occupations. In the U.S. between 2014 and 2020 the share of Nonproduction employees rose from 24% to 26%. In both countries the number of Managers has increased by 50%. The share of workers with a bachelors degree or higher is also the same, around 14%.

 

Why, despite the differences in scale and output mix in the two countries, is the composition of the workforce so similar? To some extent it must be because the methods and processes followed in design, development, construction and project management are similar, as is the use of machinery and equipment. There is not a lot of difference in some types of projects, such as commercial and institutional buildings and road and rail infrastructure. Another factor would be the geographical dispersion of activity, both are large countries and work is spread out across regions. 

 

The trend in both countries is toward fewer low skilled jobs, and this applies to both onsite labourers and offsite clerical and administrative workers. An increasing share of jobs requires qualifications, and more of these workers have university qualifications. This is not to suggest there will be no unskilled workers in future construction, but there is no reason to believe these trends have run their course.

[2] Production employees include working supervisors and all nonsupervisory employees engaged in production operations. Nonsupervisory employees includes office and clerical workers, repairers, salespersons, operators, drivers, laborers and other employees at similar occupational levels. 
[3] Construction Managers: Plan, direct, or coordinate, usually through subordinate supervisory personnel, activities concerned with the construction and maintenance of structures, facilities, and systems. Participate in the conceptual development of a construction project and oversee its organization, scheduling, budgeting, and implementation. Includes managers in specialized construction fields, such as carpentry or plumbing. From the Bureau Of labour Statistics Standard Occupational Classification.

[5]  The review of the UK's ITBs by Mark Farmer has just been released. It was done in 2023 and the data is for 2020, but it says on page 41:

"In terms of the job role make up of the construction industry, 57% are elementary level, plant or trade craft operatives. Professional, management and technical roles constitute 33% of the workforce with 10% of the workforce are in support or administrative roles.

In terms of attainment, 73% of the workforce are at level 3 and below, including 5% who are unqualified. 21% are degree level or above qualified."

Interesting because similar to Australia and the US.
