Construction Industry Policy and Industry Culture

 



In a time of rapid urbanisation and great social and environmental challenges, the built environment and associated housing, infrastructure and urban policies havebecome central issues in public policy. The quality of the built environment is a major determinant of the quality of life. Further, cities are at the centre of themodern economy and, in a fundamental sense, how well cities function depends on how well the many and diverse industries, firms and organizations across thebuilt environment sector can design, deliver and operate the projects required. The resilience of cities to climate change is being tested as temperatures increaseand fires and floods become more intense. However, because of the range and complexity of these issues it is difficult for governments to develop and implementcoordinated built environment industry policies that address these issues satisfactorily.

Industry policy was out of favour for a couple of decades before the financial crisis in 2007-08 in the US, UK and Australia, although the European Union (EU)and many Asian countries followed well developed national strategic plans. This was partly ideological, a view that policy is another government economicintervention that requires picking winners, and partly because some issues traditionally addressed by industry policy like tariffs and market access moved intonegotiations around trade policy, at both the global level and in the increasing number of regional and bilateral trade agreements.

Following the financial crisis governments looking for sources of economic growth and employment creation began focusing on specific sectors in manufacturingand services where they saw opportunity in global value chains. Environmental standards and policies supporting renewable energy were developed. Industrieslike pharmaceuticals and biotechnology, semiconductors, aerospace, IT, AI, cars and steel have featured in industry policies in many countries. Any policyintervention intended to strengthen the economy is an industry policy, and governments regularly establish priorities and target industries. Countries protect orfavour industries with legislation for many reasons but some of them are strategic and long term, like innovation programs with their associated challenges,roadmaps and milestones, and many of these programs currently involve digitization and automation in some form.

These is little practical difference between a country’s industry policy and national industrial strategy. They are both typically framed around competitiveness andproductivity, focus on innovation and R&D, and follow pathways and roadmaps through scenarios and scoping studies. Some industries like agriculture, steel andautomobiles are regarded as strategic and have always been surrounded by rules and regulations and subject to government intervention. Governments’ havescience and technology policies that influence industrial structure and macroeconomic policies that affect economic development. For many countries theemphasis in industry policy has shifted to industry 4.0 technologies and AI, as governments and industry respond to these technologies.

Government policies like these that target supply side issues are not as high profile as others, they don’t get regular updates like monthly unemployment orquarterly GDP statistics and capture attention like announcements of interest rate changes. Because productivity has become the measure used for industryperformance, despite the statistical questions that raises, it has often been the target for government policy. However, many of these policy measures will onlyaffect productivity in the long run, examples are education, training, infrastructure, innovation, R&D, capital expenditure subsidies, and pilot or demonstrationprojects. Therefore, results take time and thus take longer than the electoral cycle to develop, so there is often little benefit to the government of the day even if apolicy is working well.

When the intention of such policies is to influence a country’s economic structure and industry development they can be described as industrial strategy or industrypolicy. What history generally does show is that it is hard to get an industry strategy right and implementation is difficult. Traditionally manufacturing was thefocus for industry policy, but after 2007 the approach became more about coordinating a wide range of policies to achieve both economic and social objectives.[i]Climate change and environmental issues have become a focus for a range of industry policies aimed at reducing emissions.[ii] The rollout of protectiveequipment and vaccines during the Covid pandemic in 2020-21 both tested and accelerated this new approach.


Construction Industry Policy

As well as common industry policies targeting innovation, training or business investment, construction of the built environment is also subject to many othergovernment regulations, legislation and policies. On the demand side interest rates, taxes, public infrastructure spending, urban development and housing policiesare all important, but are also external to the built environment sector itself and are determined by a wide range of factors beyond the sector. Then there are theeffects of planning and environmental regulations and restrictions limiting the supply of new housing or infrastructure, an issue that has featured in recent debatesin many countries and spills over into other issues around the affordability of housing and the location and cost of major projects. The number of differentgovernment departments and agencies involved in regulating the built environment is often a major barrier to innovation because coordination is difficult and thereare many opportunities for incumbents to delay or derail progress when reforms are proposed.

The public sector in many countries is collectively the largest client for construction, but the expenditure is spread over departments like health, education,transport and defence, and there is unrelenting pressure from public sector clients for the lowest possible cost of work. In practice, there are significant institutionalconstraints on government buying power. Although reports in many countries have recommended leveraging public procurement of buildings and structures topush industry reform this is not widely used, despite being common practice in Asian countries like Singapore and Japan.

While it is a fact that governments can have major impacts through regulation, tax, training,  innovation and R&D policies, their effect is uneven and can be hardto discern. For example, large firms in capital intensive industries like cement respond to industry policies differently to large contractors, as do professionalservice SMEs compared to construction trade SMEs. Two areas where governments have had some success in promoting industry development are discussed inprevious posts: BIM mandates and building standards and codes.

Industry Policy and Industry Culture

Contractual relationships were the focus of much of the reform agenda of the 1990s and 2000s. In the UK the Simon Committee report in 1944 on buildingcontracts called for cultural change, as did the Latham Report 50 years later. Egan in 1998 introduced benchmarking against best practice to improve productivityand Constructing Excellence documented demonstration projects. In their book on UK Construction Reports Murray and Langford thought the ‘demands on theindustry cannot be met and so lead to an industry that cannot attract staff to deliver buildings on time, with increased costs and questionable quality.’[iii] Othercritics attacked the reform movement for its technocratic and managerial approach[iv]and the language used. By 2011, when the new UK industry strategy waslaunched, there had been little change in the industry, clients awarded projects to the lowest bidder while contractors offloaded risks and maximised profits.

That a series of UK reports were required, averaging over two a decade for 50 years (many others were not included in Murray and Langford), shows howineffective they were in developing policies to address the issues raised. The explanation for this policy ineffectiveness offered by Latham and Egan in theirreports was industry culture, broadly seen as the custom and practices underlying the business model in UK construction. Latham focused on procurement andcontractual relations with recommendations to change an adversarial culture, calling for more collaboration between clients, contractors, subcontractors andconsultants, and more cooperative practices. He recommended ‘Partnering’ between clients and contractors to realise this.

Culture is clearly important, but it is also clear that culture is not malleable and does not change easily or quickly. A better explanation for the lack of impact ofthese reports and their recommendations, and the ineffectiveness of public policy in reforming construction is required. Is the problem the policy making process,resistant to evidence and subject to ministerial whims and churn, with issues becoming politicised once they enter public debate? In a technocratic system ofproduction like construction regulatory proposals often lack a convincing evidence base, and can be poorly integrated with impact assessment and policydevelopment processes. The generic ‘problem-inspired’ industrial strategies developed by central policymakers also have to be interpreted by the ‘problem-solving’ implementers responding to nuances of local context and capability.

Construction is better viewed as three industries when the differences between residential building, non-residential building and engineering construction are takeninto account. Within the broad culture of construction they have their own permeable but distinct subcultures, based on differences in processes, products andmarkets. If the culture in each of the three industries is different, recommendations and policy directed at construction as a single industry are unlikely to berelevant across them and will thus be disregarded by many firms and clients. Clients are also different and can be generalised as households, businesses and thepublic sector, and their relationships with contractors varies accordingly. Another example is design, where house builders have pattern books, commercialbuilding uses architects, and infrastructure is designed by engineers.

These structural differences between the three industries affects the way clients, contractors, designers and suppliers will interact, thus each industry has developedindividual characteristics over time within the broader culture of construction that become that particular industry’s subculture. The specific nature of theseindustry subcultures often makes recommendations and policy directed at construction as a single industry ineffective. With separate industries and separatesubcultures, separate policies are required. A broad industry policy of the sort that targets construction as a single industry will be challenged by three deeplyentrenched subcultures with limited, though important, similarities. Research and reports that treat construction as a single industry share this problem.

The UK government mandate on use of BIM on public projects has been much more effective in the last 10 years than the previous six decades of exhortations andrecommendations to change industry culture. Recognising this, the provision of clauses covering contentious issues in construction contracts (such as intellectualproperty and data ownership) worked with rather than against industry practice and culture. The BIM Framework provided a roadmap for the firms and clients andthe development of standards provided a toolkit. Also, local governments, universities, regulators and industry bodies were all given significant but looselyspecified roles in these policies to support industry engagement.

The UK construction strategy applied to all firms involved in public projects, and thus included designers, consultants and suppliers as well as contractors andsubcontractors. The strategy targeted technology adoption not the ‘construction industry’, which is really three separate industries of residential building, non-residential building and engineering construction each with distinctive characteristics.[v] The differences in the subcultures of these separate industries accountsfor the differing rates of uptake of BIM found across firms in the UK since the launch of the strategy.

Industry culture is a complex outcome of social, institutional and economic factors. Because of the range and dynamic interplay of those factors it is not anappropriate target for industry policy, as the history of construction reform efforts that argued cultural change was necessary for industry improvement in the UK,documented over decades in a series of reports, clearly shows. When a new construction strategy was launched in 2011 the focus shifted from using publicprocurement to foster cultural change to requiring BIM on public projects, and over the next decade succeeded in increasing the use of BIM to around half of firmsand the majority of public projects. Despite all the claims made for BIM changing industry culture and increasing collaboration, if it were to come about it wouldbe as a consequence not a cause of industry improvement from the new construction strategy. Recognising this, the provision of clauses covering contentiousissues in construction contracts (such as intellectual property and data ownership) worked with rather than against industry practice and culture.

Another aspect of construction industry culture is that the nature of the work attracts many people with technical skills who use ‘technological thinking’ to findsolutions to the various problems a project will encounter between inception and delivery. Technological thinking is essentially problem-solving through trial anderror. 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. Basing policies to improve industry performance and the quality of buildings ontechnocratic measures like ISO accreditation and BIM use levels works with industry culture.

Building Standards, Energy Codes and Decarbonisation

Building Standards and Codes

 

The regular revision and upgrading of building codes and product standards is a policy area where governments, usually through regulatory agencies, have influenced and directed industry development. The use of building codes to influence industry development has a long history with some notable successes, because buildings are designed and delivered in conformance with those regulations. The building code of 1676 for the rebuilding of London after the Great Fire of 1666 classified buildings into types with specified materials and levied fees that paid for inspections. A new building code in 1844 included regulations for height, area, and occupancy of buildings.

 

Standards and codes establish allowable tolerances and how much variation is allowed for products and processes. They underpin quality control and are the basis of inspections to verify work being done, so a standard is a document structured around requirements for conformity and measures that certify meeting those requirements. During the late nineteenth century governments and insurers began raising the standards they set in building codes for access, light, safety, amenity and appearance, significantly improving the design and construction of buildings.[i]

 

The first standard was agreed in Paris for the International System of Electrical and Magnetic Units in 1881, and the International Electrotechnical Commission was established in 1906 to develop and distribute standards for the units of measurement used today. The British Standards Institution was founded in 1901, as were French and German institutes. In the US the Underwriters Laboratory was founded in 1894 by William Merrill, an electrical engineer, to provide testing of building materials for insurers, and the 1897 National Electrical Code on electrical wiring and equipment installation was the first US modern code. Insurers led the way in developing standards and methods for fireproofing the steel framed buildings that were becoming common, issuing a model building code in 1905 to reduce fire risk. Also in the US, the American Society for Testing Materials goes back to 1898 with their standard for the steel used to fabricate railway tracks. In 1902 it became the American Section of the International Association for Testing Materials, which eventually became the International Organization for Standards (ISO) in 1947. The American National Standards Institute was formed in 1918. 

 

The ISO now has more than 22,000 different standards covering every aspect of organization management and production control. National testing and standards institutes are members of the ISO, they meet annually to review programs, and countries fund it in proportion to their trade and GDP. There is a six stage process for getting a standard published, typically based on research from the member institutes, and each standard has a guide for developing and maintaining it. Multiple standards are being combined to make them easier to manage.[ii] Although agreeing new standards is a lengthy process, they are universally accepted and applied because of the rigorous scientific and engineering research they are based on. Therefore, an important element in a strategy to increase innovation in construction of the built environment is to increase funding for testing laboratories. 

 

Building characteristics like materials, access, ventilation and fire safety are regulated by standards and codes. The International Code Council produces a series of model International Building Codes that are widely used.[iii]Accreditation for standards like quality control, project management and digital twins for contractors are often required by clients. The performance of the built environment is to a large degree measured against the baselines set by standards for health and safety, energy and environmental management, and process control. When natural disasters like earthquakes, floods and hurricanes reveal shortcomings in existing standards, they lead to new standards and building code revisions.[iv] The higher standards improve resilience and drive improvements in the performance of buildings and structures. This is seen when rebuilding after fires with more fire resistant buildings due to code changes, or after earthquakes with updated standards and more durable designs. Seismic code provisions first appeared in Italy and Japan in the early twentieth century, and in the US in 1927.

 

Building codes establish a baseline for quality and performance. They protect buildings and people from collapse, fire, wind and other extreme events. They regulate structural integrity, electrical, plumbing and mechanical systems and safety, accessibility and energy efficiency. Codes thus underpin the work of architects, engineers, contractors and developers. Architects and engineers must ensure their building designs meet or exceed minimum code requirements Local authorities review plans before construction and issue permits. Inspectors verify the project is compliant. 

 

Through revisions to building standards and codes innovations and new products are introduced in an incremental but typically slow process. While that reduces risk for designers and contractors, it also affects the rate of built environment product innovation and improved building performance. Revisions can be opposed or delayed, for example by residential builders worried about increased costs in a price sensitive market or by product manufacturers protecting market share. Nevertheless, a regular review and update process like the US three year cycle for building codes keeps them relevant and focused on the key issues of building quality, energy use and embodied carbon emissions from construction of the built environment.[v]

 

 

Built Environment Decarbonization

 

The role of building standards and codes in decarbonization,[vi] reducing energy use and cutting greenhouse gas (GHG) emissions is well known.[vii] A carbon budget for both the construction[viii] and operation[ix] of the built environment is required. The UN produces an annual Global Status Report for Buildings and Construction that says: ‘Cutting building-related emissions by improving energy efficiency is a crucial aspect of meeting net zero by 2050 climate change goals. Building energy codes provide a tool for governments to mandate the construction and maintenance of low-energy buildings.’[x]

 

To do this, the energy use of buildings must be monitored and managed, and buildings must be built and retrofitted to use less energy, and a global standard for determining greenhouse gas emissions for cities is under development.[xi] There are many startups in building energy management. Although many countries, particularly in Africa, have not yet got compulsory energy codes, countries with codes have been moving toward electrification of building operations, particularly for heating and cooking. This is a necessary requirement to reach net zero by 2050 because residential energy use accounts for around 40 precent of total emissions.

 

The EU is committed to net-zero carbon emissions by 2050.[xii] EU countries’ national climate plans outline how a country intends to address energy efficiency, renewables and GHG emission reduction and meet EU targets. The Energy Efficiency Directive (EED), the framework for energy-efficiency policy in the EU, was established in 2012 with a 20 precent energy-efficiency target by 2020 and revised in 2018 with a 32.5 percent non-binding energy-efficiency target for 2030, with an increase to 39 percent proposed. The EED also targets government buildings, requiring renovation of 3 percent of the floor buildings owned and occupied in line to minimum energy-performance requirements. 

 

Legislation is based on the Energy Performance of Buildings Directive (EPBD). The 2018 amendments aim for full decarbonization of Europe’s building stock by 2050 while focusing on how to modernize the existing stock. The EPBD requires Member States to develop national long-term renovation strategies, outlining how a country aims to decarbonize the building stock by 2050. To reach the ‘2030 climate target of reducing GHG emissions by at least 55% compared to 1990, and climate neutrality by 2050, the EU must significantly increase its rate and depth of renovation, reduce GHG emissions from buildings by 60% compared to 2015, and by 2030 increase the deep renovation rate to 3% annually, up from the current 0.2%’.[xiii]

 

There is no national energy code in the US, where state, county and city authorities all play a role in setting standards and codes. Model energy codes are developed through the International Code Council and the American Society for Heating, Refrigeration and Air-Conditioning Engineers (ASHRAE). Residential and commercial buildings typically reference a version of the International Energy Conservation Code, but California and Washington have their own codes. Codes are typically decided at local or municipal level, then adopted by the state. New York City will phase-out fossil fuel combustion in new buildings from 2024, as will San Francisco and more than 40 other cities in the Bay Area. 

 

More than three-dozen US cities have benchmarking policies where owners report energy data annually to local government. Some also have building labelling, which requires owners to display an energy score or ranking based on benchmarked data.[xiv] Building performance standards set energy or emissions targets using a range of metrics, including energy intensity, GHG emissions intensity, or third-party scoring (like an Energy Star rating) for existing buildings. They get stricter over time, and as well as metrics and a target they include a plan of steps to be taken to reach the target. In 2022 eight US jurisdictions have implemented them. The graph below shows how improvements to the ASHRAE energy code are expected to close the gap to the 2030 target.

In many other countries sub-national local or regional authorities have been leading on climate change, for example in Australia the Federal Government’s reduction 26 percent target for 2030 greenhouse gas emissions is significantly lower than the State Governments’ 50 percent target. California is another example. It was the first US state to introduce an energy code in 1978, with the three year review and update cycle used in the US. Major updates included electric vehicle charging measures in 2015 and a rooftop solar mandate in 2020. California’s 2022 building code update is considering all-electric construction, meaning buildings must use electric heating and cooking appliances, with no option to use gas.[xvi]New York City in 2016 required benchmarking of energy and water use and from 2020 buildings had to display their grades (from A to F) in their entrance, based on the US Energy Star system.[xvii]

[xii] In Europe national building codes set energy requirements to induce innovation. One study found positive effects from policies to improve energy efficiency in new residential buildings, such as energy-efficient boilers and improved insulation, lighting and materials. Prices were found to have an effect on innovation for visible technologies such as boilers and lighting, but not for less-visible technologies such as insulation that are installed by builder.
