Queensland Report on Construction Productivity

 More recommendations and reform directions focused on regulation and planning

 


 

The Queensland Productivity Commission (QPC) released their interim report on Opportunities to Improve Productivity of the Construction Industry on 31st July. Construction productivity has recently been the subject of two other reports, with this one following the NSW Productivity and Equality Commission report Housing Supply Challenges and Policy Options in August 2024 and the Productivity Commission report Housing Construction Productivity: Can We Fix It? in February 2025. 

 

The motivating force behind the three reports is a political requirement to be seen to be doing something to address the housing crisis, which is fundamentally due to a mismatch between a long-term lack of supply of new dwellings and the high level of demand, driven by a combination of increased immigration and decreased household size. The result has been rising house prices, falling affordability, particularly for first home buyers, increased rents and very low vacancy rates. Another factor is the high level of engineering construction, due to the size and number of transport and energy projects, many of which are for the public sector. Queensland also has the effects of additional demand from the 2032 Olympic Games projects, currently estimated at $7 billion (which based on other Olympic Games will be much more).

 

The QPC report says ‘While many problems were identified, stakeholders were generally confident that better outcomes are possible. There is broad agreement amongst stakeholders, for many of the solutions identified, on how to address the problems facing the industry.’ Unfortunately, some 342 pages later, most of the problems discussed are about regulation and planning, onsite construction productivity barely gets a mention, there is no evidence stakeholders are in agreement on solutions and more information is requested for the recommendations, and how the problems will be addressed is not included because ‘Implementation issues, including prioritisation and sequencing, are not considered in this interim report but will be considered in the final report.’

 

This post starts with the QPC interim report’s terms of reference and Queensland construction productivity, then looks at the recommendations and reform directions in the report. Some of the report’s  key points on planning and approvals and regulation are covered, and other important industry issues and opportunities not addressed in the report are discussed. 

 

The Terms of Reference Were Extremely Broad

 

To understand how complex the issues surrounding  construction productivity are and why this report (and the others) are so unsatisfactory it is necessary to start with the terms of reference given to the QPC (heavily edited to key points) :

 

        Conditions in Queensland’s housing market, residential development, and non-residential construction, including housing supply and affordability;

        Key trends including input costs, prices, competition, and supply chain developments;

        Factors shaping Queensland’s productivity including legislation and regulation, industrial relations, procurement policies and labour force needs;

        Opportunities for improvement including regulatory and non-regulatory mechanisms;

        Priority areas for reform in the short, medium and long term (including labour, skills and competition, suitability and availability of qualified head contractors and sub-contractors etc.);

        Impact on small and medium scale subcontractors in regional areas and their ability to compete for government tenders due to regulatory requirements;

        Availability of labour, skills development, and matching supply with demand;

        How government procurement and contracting arrangements affect construction productivity, including Best Practice Industry Conditions (BPICs are wages and conditions on public projects introduced to encourage enlistment of workers);

        Barriers to entry, investment and innovation in the sector.

 

Including issues around government procurement and contracting allowed the QPC to address some important productivity determinants that were not in the other recent reports. However, the problem is the breadth of these terms of reference, and the loose or long-term relationship many of the others have with onsite construction productivity, which is what is being measured by the statistics. 

 

The QPC report, and the NSW and Productivity Commission reports that preceded it, are not really about construction productivity, which is being used as a stalking horse for the long-term lack of supply of new housing. These reports are more concerned with the complex, cumbersome and sclerotic planning and approvals process that deters, delays and prevents residential construction, and the effects of regulation and the building code.

 

Queensland Construction Productivity

 

The QPC found Queensland construction productivity is only 5 per cent higher than it was in 1994-95, compared to a 65 per cent increase in labour productivity in the market economy. As Figure 1 shows, the variation in aggregate productivity is explained by compositional changes due to the rapid growth and subsequent decline in heavy and civil engineering activity in the LNG investment boom.

 

Figure 1. Queensland productivity


 

This is also what a previous post on construction productivity in the states and territories found. In 2014 the Australian mining boom peaked with the value of work done reaching $80 billion in Queensland, mainly due to construction of three LNG plants. The pro-cyclical nature of construction productivity is clearly seen in Figure 2 as gross value added (GVA) per hour worked followed the fall in the volume of work, which declined by around 30 percent in Queensland [1].

The quotes below on the causes of slow productivity growth have been taken from the QPC report.

 

‘Although empirical evidence on the causes of slow productivity growth is incomplete, it suggests that regulation is likely to have played a key role’:

·      Evidence from the United States and New Zealand suggests restrictive land use regulation may have made it more difficult and expensive to construct housing and other buildings [2].

·      Research suggests there have been significant increases in the complexity of building regulation, which has increased overheads and construction costs.

·      Regulatory design, including regional variations, have created incentives that keep the industry fragmented and dominated by smaller firms, who are less likely to innovate and have lower productivity.

·      Where regulators have poor incentives or are underfunded, results in unnecessary delays, high administrative costs and poor oversight, which can undermine productivity.

 

‘Recent changes to the National Construction Code (NCC) have been adopted without a case being established that they would provide a net benefit to the community. Similarly, Queensland introduced its trust accounts framework without undertaking a regulatory impact assessment.’

 

‘While regulatory issues seem to be a key driver of poor performance over longer time periods, more recent productivity declines seem to have been materially impacted by policy choices relating to Queensland Government procurement.’ 

 

‘Insufficient attention has been given to how procurement practices or new projects are impacting the market. This has been exacerbated by poor project selection.’

 

‘Government procurement practices, particularly BPICs, have created unnecessary inefficiencies’

 

The Report’s Recommendations and Reform Directions

 

The preliminary recommendations are ‘specific reforms that the Commission is seeking feedback on.’ There are 21 recommendations, of which six are on planning and approvals, and four on the NCC and regulation. The recommendations are:  

 

·     Government procurement - recommendations 1, 2 and 3;

·     BPICs removal –  recommendation 4;

·     Planning and approvals – recommendations 5, 6 (infrastructure charges), 7, 8, 9, and 10;

·     Regulation –  recommendations 11 (NCC), 12 (building codes), 13 (minimum financial requirements), and 14 (trust accounts);

·     Modern methods of construction (MMC) – recommendation 15;

·     Worker health and safety – recommendations 16 and 17;

·     Workforce – recommendations 18 and 19 (occupational licensing), and 20 (mobility);

·     Utility connections - recommendation 21.

 

The reform directions are ‘areas where there is a clear case for action, but the Commission is seeking further information to support the development of specific recommendations.’ There are 12 reform directions, of which

 

·    Government selection and staging of infrastructure – reform direction 1;

·    The pre-qualification system – reform direction 2;

·    Re-setting industry practices and increasing competition – reform direction 3;

·    Tendering and contracting, including building information modelling (BIM) and collaborative contracts - reform direction 4;

·    Planning and zoning reform – reform direction5, 6 (community support);

·    Review of regulations – reform direction7 and 8 (QBCC);

·    Worker health and safety - reform direction 9;

·    Workforce - reform directions 10 (training), 11 (migration), 12 (labour hire).

 

There are also two requests for information, on the 2024 Energy Queensland Union Collective Agreement, and on foreign investor taxes and housing construction. 

 

If the aim really is to improve construction productivity, recommendations would be focused on improving project management, logistics and supply chain efficiency, increasing investment in machinery, equipment and software, contractual relations and the structure of the industry. While the recommendations on procurement are important, and with those on workforce development and industrial relations relevant to productivity, the majority of the QPC’s recommendations are on legislation, regulation, and the planning and approvals process. 

 

A comparison with the 2024 NSW Productivity and Equality Commission report Review of Housing Supply Challenges and Policy Options for NSW is useful. That report found barriers to housing supply included high construction and borrowing costs, capacity constraints in the construction sector, and bottlenecks in the development process, with over half of the 32 recommendations on planning. It recommended reforming planning to streamline the development process and reduce approval times, and reviewing planning policy because ‘prescriptive rules’ on land block innovation. Other recommendations included education and skills, business regulations and tax, improving infrastructure and transport, replacing stamp duty with a land tax, establishing an Urban Development Program to report on the housing market and a housing supply council to advise on housing targets, and incentives for local government to meet targets. It argued for non-regulatory approaches wherever possible, and avoiding excessive regulation. While there are many overlapping recommendations, this is a more ambitious agenda than the one envisaged by the QPC. 

 

The structure of the QPC Interim  Report echoes the Productivity Commission’s February report, which had five issues and seven reform directions. The PC’s issues were: the complex and slow approvals process; fragmentation due to regulation; the lack of innovation; the regulatory burden; and workforce issues. The reform directions were: coordinated and transparent planning approvals and appropriately funded regulators; review building regulations and the NCC’s objectives; implement ratings systems on new and existing building quality; increase diffusion of technology; public research and development funding; reduce regulatory impediments to MCC; and improve workforce mobility and flexibility. The PC suggested states should consider establishing coordination bodies to speed up the process and address delays such as the Queensland State Assessment and Referral Agency, which got two mentions but no discussion in the QPC report [3]. 

 

The Planner Productivity Problem

 

Over 45 pages the QPC details regulation of land use that ‘can be complex, restrictive, inconsistent across local governments, inconsistent between regulatory instruments and impose costly and unnecessary requirements’, a planning system that ‘is complex, difficult to navigate, inefficient and lacks transparency and accountability’, and approvals processes that ‘create uncertainty, have high transaction costs, require expensive or unnecessary modifications to building design or cause excessive delays.’ 

 

The QPC recommends an alternative development pathway for significant developments [4], amending the Planning Regulation, and reviewing the Building and Planning Acts. The Government should ‘investigate digital planning and permitting technologies to improve the efficiency, accuracy and transparency of the approval process.’ To ‘build community support for housing development’ the QPC suggests improved consultation, citizen panels, independent hearing panels, and negotiable conditions. To improve zoning financial incentives for local government might be used. 

 

It is universally recognised that the time and cost of development approvals is a problem, but that is an issue of planner productivity not construction productivity. Research from YIMBY Melbourne found ‘In 1986, for every practicing planner, Australia built around 54 homes. Now, we build fewer than nine homes per planner. A planner 40 years ago was on average responsible for the development of six times the number of homes per year than a planner working today.’

Source: There is no planner supply shortage, YIMBY Melbourne Research Note. 

 

The Research Note concluded ‘The demand for planners has mainly increased not through an increase in construction output and project delivery, but through an increase in regulatory process and complexity.’ This is QPC’s reform direction 4, and addresses 

the problem that development projects such as new housing estates and apartment complexes can take ten years or more to complete, with most of the time spent getting approvals. 

 

Regulation and the NCC

 

The QPC says ‘evidence suggests that several regulations affecting the construction industry are not effective or efficient, and are likely to be reducing productivity. Building regulations are becoming more complex with increased risk they are impeding productivity. Reduced levels of attention are being paid to the costs of new regulation, with regulatory best practice not being followed.’

 

Figure 4. The Queensland building regulation system

 


 

The outcome is the QPC’s view that recent changes to NCC 2022 for liveable housing and energy efficiency have increased construction costs, and ‘regulatory impact analysis undertaken showed these benefits were unlikely to justify the costs they impose.’ The recommendation is for Queensland to opt out of NCC 2022 and ‘only adopt future NCC changes in Queensland codes where these have been through robust regulatory impact analysis to demonstrate they provide net benefits to the community.’ 

Under Reform direction 8 ‘consideration should be given to whether the regulatory framework underpinning the QBCC provides the right incentives for ongoing

improvements to regulatory performance.’

 

Modern Methods of Construction and BIM

 

There is a short chapter in the interim report on MMC, included in the section on regulation. The QPC argues there is no market failure and no reason for government intervention to promote MMC. The report makes some general observations about regulatory barriers to MMC, none of which are new, and did not endorse MMC as an alternative to conventional building. There is no discussion on the cyclical boom-bust nature of residential building, which makes industrialisation of modular and prefabricated housing difficult, the reluctance of most banks to finance modular and prefabricated houses, and the lack of standards or an industry quality assurance accreditation system for modular and prefabricated buildings. 

 

The QPC acknowledges the existence of the MMC program that QBuild and the Office of the Queensland Government Architect have, which is a partnership with 12 industry suppliers to supply housing in regional and remote areas. In 2023 QBuild established a training and production facility at Eagle Farm in Brisbane, and two more production facilities have since opened in Zillmere in north Brisbane, and Cairns in Far North Queensland. 

 

Although QBuild has the best developed MMC program in Australia that has produced over 500 houses, the QPC does not discuss or make any recommendation on the program. The QPC did not use the opportunity to report data from QBuild on MMC productivity, costs and time performance, or provide feedback from occupants on the build quality and  liveability of their houses, or from users of modular or prefabricated public buildings like schools and hospitals. 

 

Another oversight is the lack of discussion on the use of Building Information Modelling (BIM) or other digital tools like design for manufacture and assembly (DfMA). These are making offsite manufacturing of building modules and components more efficient and have been used for over a decade. At the end of the section on Contracting for Efficiency the QPC asks for information on ‘the key barriers to increased adoption of digital technologies, such as BIM, and the policies or practices that would allow the opportunities for digital technologies to be fully leveraged.’

 

Queensland has had a BIM mandate for public projects over $50 million since 2019, however the QPC does not think this worth mentioning or, worse, investigating. This was another missed opportunity to assess the costs and benefits of their BIM mandate, and the failure to recommend its retention and/or extension a mystery. Also, the BIM mandate is under the Queensland Department of State Development and Infrastructure, which has a 2024 Infrastructure and Workforce Productivity Plan with details on current and planned initiatives, The QPC does not refer to this plan or its effectiveness [5]. 

 

Industry Issues

 

There are other important industry issues not discussed, starting with construction costs and the volatility of the building cycle. Improving productivity through better project management and reform of the VET system are also overlooked. There is no discussion of digitisation and automation, digital tools and platforms, AI enhanced systems, and automated planning and code compliance checks. Also, industry contractual relationships and risk allocation are not considered. Subcontracting is flexible and a method to manage costs and risk, but direct employment has a smaller span of control and is more efficient. 

 

Although there is extensive coverage of building regulation and the NCC, the QPC does not discuss building defects and the lack of implementation of the 2018 report Building Confidence: Improving the Effectiveness of Compliance and Enforcement Systems for the Building and Construction Industry Across Australia recommendations on mandatory inspections and fire safety. Nor is the problem of flammable cladding in Queensland in the report, where from 2019 to 2023 there was a Safer Buildings Taskforce to advise the government on policies and actions and how to rectify combustible cladding. In August 2025 three public buildings still needed rectification and some unknown number have been rectified and removed from the online list on The Department of Housing and Public Works page, which says: ‘As of 31 May 2024:

·       976 private buildings require a solution to address cladding risk;

·       308 are potentially at risk and need to complete the checklist process;

·       345 have notified of removal or rectification.

 

Although the terms of reference were to look at other jurisdictions, there is no discussion of the NSW iCIRTsystem, developed by ratings agency Equifax, for assessing contractor and consultant capability and performance, despite clear evidence of the effectiveness of the system in NSW in improving building quality and addressing the problems of building defects and phoenixing by developers and contractors. Discussion of the 10 year latent defects insurance scheme that has started in NSW is also missing. 

 

Conclusion

 

The QPC has focused on regulation and planning as the main issues, but these are just two of the factors that affect onsite productivity, and arguably skills, technology and project management are more important. Also, while no-one disputes the importance of issues like costs, prices, competition, the supply chain, labour, skills, occupational licensing, procurement and contracting, these have been discussed and dissected over and over again. The QPC makes no new contribution to these issues.

 

The QPC’s 21 recommendations and seven reform directions are in four key areas. The first is improving government procurement policies, where well-known ideas on collaborative contracting, and selecting, sequencing, and sizing of public projects are recycled. These would all make the Queensland Government a better client and would probably increase productivity on public projects, but that can only have a small effect on the overall level of construction productivity in the state because most of the work done is for the private sector. The Queensland Government (and the other Australian Governments) have received these recommendations many times over the years. 

 

The second key area is improving land use regulations, including approvals and zoning, which are a third of the recommendations. The QPC does not directly address the reality that local government opposes new housing, although it does recommend an alternative development pathway for significant developments and reviewing the Building and Planning Acts. The issue here is planner productivity, which has fallen as regulatory complexity has increased, not construction productivity. Planning and zoning decisions have no effect on supply side issues such as the cost of construction materials and mortgage finance for new housing, providing the infrastructure needed for new developments, and the rate of conversion of approvals into commencements by developers.

 

The third key area is the regulation of building activity. The QPC recommends opting out of the 2022 NCC updates on building accessibility and thermal performance because of their cost effects, reviewing the regulatory framework and performance of the QBCC, and pausing rollout of trust accounts while investigating their costs and benefits. The QPC argues no government support for MMC is required, but regulatory barriers should be addressed. 

 

The fourth key area is improving labour market operation, mainly through reform of apprenticeship and training pathways, occupational licencing, skilled overseas migration, labour hire licensing, and allowing recognition of qualifications from interstate. These issues were recognised and had similar recommendations in the NSW and Productivity Commission reports. 

 

What the QPC report shows is that construction productivity in general, and residential productivity in particular, is being used as a stalking horse for the lack of supply of new housing. As in the previous reports from the NSW Productivity and Equality Commission and the Productivity Commission, the main focus is on a sclerotic planning and approvals process that delays and often prevents new housing. The real issue there is local government opposition to new housing and planner productivity, not construction productivity. 

 

Houses are larger and apartments smaller than a few decades ago, but how they are procured and built, and what they are made of, has not substantially changed in decades. Fundamentally, that is also why the level of productivity has not changed. While there are more electrical appliances and offsite manufacturing of trusses, windows, doors and cabinetry, the building structure and services like electricity, water and plumbing in a 1960s dwelling are those found in a new build today.

 

Construction in general and housing in particular has a well-established system of production that is efficient and flexible. It will only change if and when there is a clearly superior method of delivery that is also profitable. Tinkering with regulations, the NCC, planning and approvals processes, and occupational licensing might make a difference at the margin, but will not deliver the big improvement in productivity that is required. For that a commitment to increased digitisation and automation is necessary, with government policies, procurement and finance aligned. 

 

There are some glaring omissions in the report. The QBuild MMC has produced over 500 houses, but the QPC does not discuss or make any recommendation on the program. Queensland has had a BIM mandate for public projects over $50 million since 2019, however the QPC does not think this worth mentioning or, worse, investigating. There is almost no discussion on the use of BIM or other digital tools like design for manufacture and assembly. Construction costs and the volatility of the building cycle, improving productivity through better project management and reform of the VET system are also overlooked. Although there is extensive coverage of building regulation and the NCC, the QPC does not discuss building defects and the lack of implementation of the 2018 Building Confidence report. 

 

The productivity issues in the QPC report are not new and can be found in many other reports on the industry, although there are some that are specific to Queensland. The interim report’s recommendations are limited and most would be little more than modifications to the current system. While those may be worthwhile, because the current system can clearly be improved, there is no suggestion that a more radical approach might be needed or taken.

Australian Construction Productivity

Is the industry’s productivity as bad as claimed?






 

The Australian Bureau of Statistics publishes productivity measures for the whole economy, the Market Sector, and for the 16 industries that make up the Market Sector. Productivity is the ratio of output and inputs and is affected by innovation, research and development, education and training, the quality and age of the capital stock (of machinery, plant and equipment, buildings and structures), the rate of technological change and adoption of new technologies.  The effects of all these factors takes time, so productivity is a long-run measure that changes gradually. 

 

The post compares Construction productivity to the performance of the Market Sector. The data used is from the annual ABS Productivity Statistics release, which has data from 1994-95 to 2023-24 (the most recent release was February 2025). The ABS productivity indexes are based on 100 in 2022-23, however for this analysis they have been first rebased to 100 in 1994-95 to compare the long-run growth of Construction and Market Sector productivity, and then rebased at 100 in 2015-16 for comparing productivity in the short-run. 

 

Comparisons are made for labour productivity and multi-factor productivity (MFP) using both the hours worked and quality adjusted labour input measures. The quality adjusted labour input indexes take into account characteristics of the workforce like years of education, levels of training, industry of employment, age and sex. These quality adjusted measures reflect changes in the composition and skills of the workforce, and typically have a lower rate of growth than the hours worked measure. Capital productivity is also shown. 

 

As well as comparing the different measures of productivity for Construction and the Market Sector, there is data for the individual industries that shows Construction is in no way the worst performing industry, although it is far from the level of growth seen in the best performing industries.

 

 

Productivity Since 1995

 

The long-run performance of Construction includes a sharp rise during the mining boom between 2012 and 2015, followed by a gradual decline over the next few years as these major resource projects completed [1]. At the end of the mining boom productivity had fallen to around the level it was before the boom. This pattern was due to the large increase in Construction output during the mining boom because output included plant and equipment like the offshore drilling platforms and gas liquefaction plants, none of which involved much construction work and most of which was imported. Productivity increased because this statistical quirk increased output much more than employment and hours worked [1]. 

 

Labour Productivity

 

Starting with labour productivity over the long run since 1994-95, the difference between growth in the Market Sector and the lower productivity growth of the Construction industry is apparent in Figure 1. However, despite claims made that there has been no growth in Construction labour productivity, there has been an increase. Construction labour productivity has increased by 17% on an hours worked basis and 24% on the quality adjusted labour input basis which, although less than the Market Sector’s 64% and 41% respectively, is not nothing. 

 

Figure 1. Market Sector industries labour productivity

 


Source: ABS 5260. Gross value added per hour worked. Quali is the quality adjusted labour input measure. 

 

As Table 1 shows, since 1995 the three leading industries for hours worked labour productivity growth have been Agriculture, forestry and fishing 210%, Information media and telecommunications 228%, and Financial and insurance services 123%. The two industries with lower growth than Construction were Mining 6%, Electricity, gas, water 2%, and Administrative and support services had negative growth of -13%. 

 

For quality adjusted labour productivity, Construction had better growth than Rental, hiring and real estate services 4%, and there were three industries with negative growth: Mining -2%, Electricity, gas, water and waste -9%, and Administrative and support services -23%.

 

Table 1. Market Sector industries labour productivity change



 

Multi-factor Productivity 

 

The ratio of output to input of combined labour and capital is multi-factor productivity (MFP). For MFP the story is not as good as for labour productivity, because there has been only 1% growth in Construction hours worked MFP and a 3% fall in the quality adjusted measure.  Market Sector growth on the hours worked basis was 23% and on the quality adjusted labour input basis was 13%. After MFP rose and fell during the mining boom, instead of returning to the preboom level there was collapse in Construction MFP after 2015-16.

 

Figure 2. Market Sector industries multi-factor productivity

 


Source: ABS 5260. Gross value added per hour worked. Quali is the quality adjusted labour input measure. 

 

The 1% increase in Construction hours worked MFP is very small, but not the decline often claimed for the industry. Table 2 shows four industries had a fall in hours worked MFP since 1995:  Mining -28%, Electricity, gas, water -30%, Rental, hiring and real estate services -32%, and Administrative and support services -16%. The three high growth industries were: Agriculture, forestry and fishing 182%, Information media and telecommunications 64%, and Financial and insurance services 63%. 

 

Construction, however, was one of five industries with negative quality adjusted labour input MFP growth, although at -3% it had a much smaller decline than the other industries of Mining -31%, Electricity, gas, water and waste -33%, Rental, hiring and real estate services -36%, and Administrative and support services -25%. This raises the question of why Construction is singled out as the problem industry. 

 

Table 2. Market Sector industries multi-factor productivity change




 

Capital Productivity

 

Capital productivity has been falling for both the Market Sector and Construction since the early 2000s.  This is a complex measure, because estimating the stock of capital requires an estimate of annual capital investment and a depreciation rate to account for declining efficiency of the existing stock due to use and age. Although Construction capital productivity peaked in the mid 2000s and declined during the mining boom, the post-boom fall in MFP was due to the sharp decline in capital productivity, because since then labour productivity was more or less flat but capital productivity was falling. As Figure 3 shows the Market Sector also had declining capital productivity, but after 2015-16 the decline in Construction capital productivity was much worse. 

 

Figure 3. Market Sector industries capital productivity 

 


Source: ABS 5260. 

 

What these long run graphs show is that there was a downward shift in Construction productivity around 2015, when both MFP and capital productivity went into significant decline. Up until then Construction productivity had been similar to Market Sector productivity for MFP, but after 2015 the Market Sector and Construction industry measures diverged. The next section looks at productivity over the short run since that divergence.

 


Productivity Since 2015-16

 

Labour Productivity

 

Labour productivity in the short run since 2015-16 has a distinctive and interesting pattern. The hours worked measure has fallen 4% from 100 to 96 but the quality adjusted labour input measure has increased by 6% from 100 to 106, and was in fact higher then both Market Sector measures in 2023-24. The increase in the Quali index occurred in the 2019-20 year with a big jump from 95 to 104, and there has been a gradual increase in the years since. 

 

Figure 4. Market Sector industries labour productivity 

 


Source: ABS 5260. Gross value added per hour worked. Quali is the quality adjusted labour input measure. 

 

The increase in the Construction quality adjusted labour input measure index will be the result of changes in the composition of employment, with the combined share of Professionals and managers increasing from 15% to 18% between 2019 and 2020, and peaking at 19% in 2022. Figure 5 shows the share of Professionals increased from 4% to 6% in 2020, and for Managers the share rose rom 10% to 12% in 2020 and was 13% from 2021 to 2023. In 2024 Technicians and trades workers were 50% of Construction employment, and Machinery operators another 6%, and their combined shares in total Construction employment have decreased by 3% since 2016. The share of Clerical and administrative workers has also declined, by 0.6%. Therefore, since 2016 the overall makeup of Construction workforce has become more skilled and qualified, raising the quality adjusted labour input measures [2]. 

 

Figure 5. Share of total Construction employment

 


Source: ABS 6291

 

Between 2016 and 2024 there were large differences in the productivity performance of the 16 Market Sector industries. As Table 3 shows, on the labour productivity hours worked basis there were two industries with high growth: Agriculture, forestry and fishing 44%, and Information media and telecommunications 40%. Four industries had growth between 10 and 20%, and five had growth less than 10%. Construction -4% was one of five industries with negative growth, the others were Mining -15%, Manufacturing -4%, Electricity, gas, water and waste -15%, and Financial and insurance services -4%.

 

On a quality adjusted basis Construction was the only industry to improve on the hours worked measure, all other industries had slightly lower quality adjusted labour input growth than hours worked. The other four industries with negative hours worked labour productivity again had negative quality adjusted labour input labour productivity growth. There were only six industries with better quality adjusted labour productivity growth than Construction’s 6%: Agriculture, forestry and fishing 41%, Wholesale trade 7%, Accommodation and food services 8%, Information media and telecommunications 33%, Professional, technical and scientific services 14% and Administrative and support services 12%.

 

Table 3. Market Sector industries labour productivity change



 

Multi-factor Productivity 

 

The MFP indexes for Construction do not show the same pattern as labour productivity. Both the hours worked and the quality adjusted indexes have fallen since 2016 and have closely followed each other down, ending at 92 and 91 respectively in 2024. However, the Market Sector has not performed particularly well, with the quality index only increasing to 101 and the hours worked index increasing to 104.

MFP growth since 2016 is similar to labour productivity with a couple of exceptions. Table 4 shows on the hours worked measure only Agriculture, forestry and fishing 44% had high growth, and there were three industries above 10%. Five industries had negative growth: Construction -8%, Mining -3%, Manufacturing -1%, Electricity, gas, water and waste -15%, and Arts and recreation services -1%. Again, the growth in the quality adjusted labour input measure was lower than for hours worked, with Construction -9% one of eight industries with declining productivity, including Mining -3%, Manufacturing -3%, Electricity, gas, water and waste -16%. Transport, postal and warehousing -3%, Rental, hiring and real estate services -1%, and Arts and recreation services -3%.

Capital Productivity

 

The performance of capital productivity has been particularly poor for construction, falling from 100 to 85 between 2016 and 2024, while the market sector index barely increased and ended at 103.

Misunderstanding Productivity

 

There are two common misunderstandings about Construction productivity. One is that increasing offsite manufacturing and use of modern methods of construction like prefabrication and modular buildings will increase measured Construction productivity. It will not, because that work will be included by the ABS in the Manufacturing industry subdivisions of Prefabricated steel and timber buildings, Concrete products, and Structural steel. In fact, one reason for the lack of growth in measured Construction productivity has been the gradual but continual shift to more prefabrication and offsite manufacture. 

 

A second misconception is that improving Construction productivity will somehow decrease the cost and increase the number of dwellings being built. This mistakes new construction for the market for housing, where in the short-run price is determined by the interplay of demand and an inelastic supply of new dwellings due to limited industry capacity to build and lengthy approval times. Increasing onsite productivity might decrease the time to complete a build but will have a marginal effect on the total cost of delivery, and the number of dwellings built is determined by project feasibility (i.e. the profitability of development) at any one time. Improving Construction productivity might help, but on its own cannot and will not solve the housing crisis. 

 

Conclusion

 

That the Construction industry has had no or negative productivity growth for the last few decades has been repeated so many times by so many commentators it has become an accepted fact about the industry. There are, however, four different measures of productivity, and commentators can focus on those that support their claims, and productivity growth rates vary considerably over different time periods, allowing selective choosing of comparisons. 

 

The four productivity measures are labour productivity on an hours worked basis or quality adjusted labour input basis, and multi-factor productivity (MFP includes the capital stock) also on an hours worked basis or quality adjusted labour input basis. The ABS productivity statistics for the Market sector go back to 1994-95, and this analysis has been for two periods, the long-run from1994-95 to 2023-24 (the latest data) and the short-run period of 2015-16 to 2023-24, chosen because 2015-16 was the end of the rapid rise and fall in Construction productivity during the mining boom. 

 

When the productivity of Construction is compared to the Market sector, despite claims that there has been no growth in Construction labour productivity, there has been an increase. Since 1994-95 Construction labour productivity has increased by 17% on an hours worked basis and 24% on the quality adjusted labour input basis which, although less than the Market Sector’s 64% and 41% respectively, is not nothing. Construction is in no way the worst performing industry, although it is far from the level of growth seen in the best performing industries.

 

In Australia there is a wide difference between a group of high productivity growth industries and a group of low or negative productivity growth industries. On the hours worked measure for labour productivity, since 1994-95 there were three high growth industries, and ehree industries with lower growth than Construction. For quality adjusted labour productivity, Construction had better growth than Rental, hiring and real estate services’ 4%, and there were three industries with negative growth. 

 

For MFP the story is not as good, because since 1994-95 there was only 1% growth in Construction hours worked MFP. That 1% increase in Construction hours worked MFP is very small, but not a decline. Market Sector growth on the hours worked basis was 23%, and on the quality adjusted measure Market Sector growth was 13%. On the hours worked basis there were three high growth industries, and four industries had a decline. Construction was one of five industries with negative quality adjusted labour MFP growth, although at -3% it had a much smaller decline than Mining -31%, Electricity, gas, water and waste -33%, Rental, hiring and real estate services -36%, and Administrative and support services -25%. This raises the question of why Construction is singled out as the problem industry. 

 

Construction capital productivity peaked in the mid 2000s and falling MFP was due to this decline in capital productivity. The Market Sector also had declining capital productivity, but there was a downward shift in Construction productivity around 2015, when both MFP and capital productivity went into significant decline and the Market Sector and Construction industry measures diverged.

 

There is a notable difference between the quality adjusted labour input measures and the hours worked measures for Construction labour productivity since 2015-16, because the hours worked measure has fallen 4% but the quality adjusted labour input measure has increased by 6%. The increase in the Construction quality adjusted labour input measure index will mainly be the result of changes in the composition of employment, with the combined share of Professionals and Managers increasing from 15% to 19% in 2022. The Construction workforce has become more skilled and qualified, raising the quality adjusted labour input measures.

 

Between 2016 and 2024 on the labour productivity hours worked basis there were two high growth industries, four industries had growth between 10 and 20%, and five with growth less than 10%. Construction -4% was one of five industries with negative growth, the others were Mining -15%, Manufacturing -4%, Electricity, gas, water and waste -15%, and Financial and insurance services -4%. On a quality adjusted basis Construction was the only industry to improve on the hours worked measure, and there were only six industries with better quality adjusted labour productivity growth than Construction’s 6%.

 

For MFP growth since 2016 on the hours worked measure only Agriculture, forestry and fishing had high growth, and there were three industries above 10%. Five industries had negative growth: Construction -8%, Mining -3%, Manufacturing -1%, and Electricity, gas, water and waste -15%. Again, the growth in the quality adjusted labour input measure was lower than for hours worked, with Construction -9% one of eight industries with declining productivity, including Mining -3%, Manufacturing -3%, and Electricity, gas, water and waste -16%.

 

Clearly, Construction is far from the worst performing industry, which raises the question of why it is so often singled out for low productivity growth. There were only six industries with better quality adjusted labour productivity growth than Construction. And are industries that have had declining productivity like Mining or Electricity, gas, water and waste not important? Should their productivity performance not be scrutinised? 

 

Maybe Construction could do better, but there have only been a few high growth industries in Australia over recent decades. Construction is one of a group of low growth industries, and compared to those industries its performance has been much better in both the long and the short-run. Instead of complaining about low productivity growth, attention should be focused on addressing the issues that have negatively affected Construction productivity, such as the number of micro and small firms, lack of standardisation of structural elements, the low level of investment in software and capital stock, state based occupational licensing and building codes, procurement methods, financing and project management, and education and training systems [3].
