Corporate Strategy in Construction



Cost Curves and Competencies


Every so often something reminds me of the fact that building and construction is different from other industries, and Walter Kiechel’s book The Lords of Strategy: The Secret History of the new Corporate World was one of those experiences.

The strategists of the title were the men who founded the firms and created the modern management consultant industry. These men (and with few exception the characters in the book are all men, many of them with engineering degrees) and their ideas have fundamentally changed the world we live and work in through their effect on the corporate world, and in particular their effect on the largest global corporations that dominate the modern industrial and post-industrial economic landscape.

So this book is interesting for several reasons. The first is the story it tells about how management consulting developed from the 1960s and the manner in which it became a central player in business development. The second is that it is really a history of ideas, or from another perspective the intellectual history of an idea. The third is the way the interaction over time between the consultants with their ideas and business facing challenges changed both.

On the face of it the story of how management consulting developed and how it became a central player in business development is not a promising topic. But this turns out to be wrong, mainly because Kiechel knows so much about his subject after a career spent observing managers of major US corporations for many years, as Managing Editor at Fortune magazine and as Editorial Director of Harvard Business Publishing. He gives an inside account of the birth and evolution of strategy as the dominant business paradigm of the second half of the twentieth century.

The founder of the Boston Consulting Group (BCG), Bruce Henderson, was the originator of business strategy as we know it today. His first insight was the importance of the experience curve, or the decline of unit costs as production volumes increase (also called the learning curve effect). No other idea has had such a large impact on corporate consciousness, despite its weak empirical support: "As the 1960s unfolded, fattish, complacent American companies found themselves confronted with competition from unexpected quarters foreign manufacturers, smaller upstart enterprises in their own backyard. What was going on? What to do? The BCG had the answer to both questions in the form of the experience curve”.

The large industrial companies that turned to BCG were of course doomed to decline from their peak in the early 1970s. However, BCG gave them the tools to fight back, mainly in the form of detailed data on their costs, capital structure, customers, competitors and market shares, data these firms had never had or needed before. This data was then integrated by BCG into a corporate strategy based on gaining market share, to drive down costs by increasing production, not maximising short-term profits. Radical stuff.

The best-known concept to come out of BCG is the growth-share matrix. This ubiquitous diagram of cash cows, dogs, stars and question marks pulled together all the elements of strategy BCG thought essential. As a single, conceptual device it was a thing of beauty that captured with brutal honesty a corporations situation and the decisions to be made. It also made BCG a load of money because analysing a companys product portfolio was a lot more lucrative than drawing experience curves.

In 1973 BCGs best salesman left to form his own company. Bill Bain wondered what happened for BCG clients after the consultants report was handed in, with all the insights and data it contained. Did the clients make more profits? Did anyone know? Bain and Company did not take on projects for clients, like BCG, but had an ongoing relationship, paid monthly, with only one client from an industry, or more exactly one client from a competitive set. With this approach Bain stole a march on its competitors by taking on implementation, the nuts and bolts of managing a strategy.

Bains slogan (its value proposition) could have been We dont sell advice by the hour; we sell profits at a discount.” The keys to profits were costs and processes, and Bain developed the ideas of best practice and benchmarking, and measuring the results by a company’s share price growth. If you have wondered where the modern obsession with measurable results originated, Bain and Companys work in the 1970s and 80s would be the place to look.

The third global consulting firm is McKinsey and Company. The oldest of the three it was founded by an accountant in 1926, and in the 1950s and 60s focused on helping large companies shift from the traditional functional form to the new divisional model of organisation. However, in the 1970s it was in the doldrums and falling behind its competitors. The book tells the story of how Fred Gluck went from being a rocket scientist for Bell Labs to the founder of McKinseys strategy practice, and in the process turned it into a firm of strategy buffs’. Indeed, by the mid-1980s McKinsey had arguably become the leading strategy firm, and had put the full weight of its prestige and reach behind the strategy revolution started by Bruce Henderson.

The next character introduced is Michael Porter who would eventually become the most famous business-school professor of all time. To get there, though, he would have to fight off academic elders who wanted to deny him a job, and then thoroughly disrupt both the curriculum and the pedagogy of the Harvard Business School.”

When Porter’s book Competitive Strategy came out in 1980 it may have built on the consultants previous work, but it also laid out the possible choices of strategy (three) more clearly than anything done before, and put strategy at the centre of both business management and business school teaching. The book is now in its sixtieth printing and business education has never been the same since. The story of Porters experience at Harvard is an engrossing example of overcoming entrenched conservatism in academia.

One of the criticisms of Porter’s ideas is the lack of a human element, his corporations do not appear to have people working in them. In 1982 Tom Peters and Robert Watermans book In Search of Excellence put that right, and went to the top of the best-seller lists. Peters had left McKinsey a few months earlier and Waterman left after the books success. They emphasised the centrality of people to a companys success, although this turned out to something of a short-term victory against the prevailing management view.

Excellence also turned out to be difficult, within five years half of the 43 companies on Peters and Watermans list were in trouble. The wave of similar books that followed, with their stories of success, all found the same problem. Success is transitory, performance is impermanent, but corporations, especially large corporations, go on. More precisely, the human factors like norms and behaviours that make up what we call corporate culture persist. This turned the focus of attention onto the implementation of strategy, which is neither as sexy nor as stimulating as solving problems for a new client. What it did do was build client relationships and make Porter’s value chain the closest thing we have to a universal concept in business strategy.

Over the final chapters Keichel surveys a number of the key features of the contemporary corporate landscape. These include financial engineering, leverage and buyouts, the arrival and departure of core competencies and capabilities, and the impact of technological development and the internet. This is all interesting stuff, although these chapters lack the focus of the earlier part of the book, and unlike the original ideas in the strategy revolution none of these ideas are secrets because they have been extensively promoted by their authors. What they do is highlight just how influential in forming the contemporary corporate landscape the ideas have been.

That is one of the genuinely important insights this book gives us. Many of the conventional wisdoms heard from chief executives these days are recycled and re- treaded ideas from the early days of the strategy revolution. For better or worse these ideas have been instrumental in developing modern management methods, and in doing so have directly affected the lives of millions.

It is striking how this book shows up differences between the building and construction industry and the manufacturing, banking and finance industries where the strategy consultants were most influential. The most significant difference is the limits to corporate strategy in an industry based on tendering and low-price bidding. For many, probably the great majority, of projects, price is the only strategy. While there are contractors that specialise in a particular type of work, Westfield in shopping malls for example, and the largest have become geographically diversified through takeovers, these are the exceptions that prove the rule. Strategy, in the way it is used in this book and in other industries, is not an obviously important factor for most contractors.

The second key difference is the lack of a meaningful experience curve effect. Costs are not closely related to volume or market share, so Bruce Hendersons idea would not have much impact on a typical construction firm. Closely allied to this is the lack of opportunity and/or unwillingness of most clients to invest in developing long-term relationships with contractors and other industry suppliers. Where this has been done there have been clear gains in efficiency and reliability.

That said, construction is a more diverse industry than most, in terms of types of projects and characteristics of firms. It may be that the technological or organisational conditions for a strategy revolution in construction have not yet been put in place, although there are signs that this is changing.

The type of frontier firms discussed here clearly have strategic intent behind their move from the process-based contracting and project management business model to a more product focused approach. The increasing degree of industrialization and automation across the industry, and the rollout in late 2016 of systems like Trimble Connect, may signal a tipping point is being reached. McKinsey has become deeply involved in the industry since 2010, focused on clients and infrastructure as discussed here and here, and the McKinsey Global Institute has produced some interesting reports over the last couple of years. Other consulting firms like Deloittes are also starting to pay more attention to the industry.

The Use of Drones in Construction

 The Cutting Edge No. 2


This is a collection of reports on the web from the last year or so on how and where drones have been used. There is probably a lot of other research and use going on that is not available and has not been reported, or is not on company or university websites, but I think this gives a fair idea of the state of play.

Drones are the big new thing in construction at the moment, but as always with new construction technology it is hard to get a good idea of how widespread their use, is or indeed how useful they are. Given the rapid uptake of BIM, tablets and apps in the US industry (see here and here) its not surprising that they also appear to be at the cutting edge with drones. That said, its hard to know how good the integrated systems from Skycatch and Droneview actually are, as there are no independent reports available so far. On the other hand, these companies have already got commercial products onto the market, and appear to be the first entrants.

It is worth noting that one effect of drones that monitor site progress against plans and schedules will be greatly increased transparency of project performance. I’ll discuss that topic in a later post, but there are some obvious implications of quality real-time information for clients, contractors and workers, though different in each case.



Drones are in regular use at Crossrail, a big project in London about to finish, although as far as I can tell they only have two in operation:
  • Site inspections - close examination of high-risk areas, and speedy overviews of large sites, freeing up time for other tasks.
  • Health and safety Induction – site plans can be quickly and efficiently updated to show where different works are taking place ensuring that operatives stay safe.
  • Crane, tower and scaffold inspection – a much easier method of doing inspections, providing real-time footage to spot anomalies. This reduces site downtime and mitigates risks of personnel having to work at height.
  • Site planning – overviews can be obtained quickly to inform planning sessions.
  • 360° panoramas – a more immersive experience to enhance appreciation of potential hazards and site orientation.


The French company claims to be a leader in the field, with four subsidiaries using drones:
  • Omexom, the subsidiary that handles electricity grids, is using helicopter-style drones to observe the condition of pylons and insulator chains.
  • At Eurovia drones are used in quarries to carry out topographic surveys and measure the likely reserves of the aggregate.
  • Nymphea uses underwater drones, known as remote survey vehicles, to assess the condition of structures such as bridge caissons, either with visual cameras or with acoustic devices that measure the extent of corrosion on metal structures.
  • Vinci Autoroutes uses drones that hover about 100m above the ground to build a 360 degree picture of the landscape along a particular road. The idea is to enable clients to see themselves from above, which they can do by linking to the drone’s cameras with their mobile phones or tablet computers.



The US contractor’s drone programme is the result of its decision in 2013 to team up with Skycatch a Californian start-up that attracted investment from Google, among others. The firm was founded to build drones for data collection on building sites. Christian Sanz, the founder and chief executive of Skycatch, said the aim was to have a fleet of drones continually flying over the works to capture real time information about their progress, prevent mistakes and detect unsafe situations.

Bechtel uses the technology to collect real-time environmental data such as air quality and temperature, monitor safety, survey difficult and inaccessible terrain and track real-time construction progress. The data collected can be stored in a cloud and viewed on site using handheld and desktop computers using the Skycatch dashboard. The technology was used at Bechtel’s three Curtis Island LNG projects in Australia, which are more or less complete and now in production.


 

Komatsu’s Smart Construction uses automated dozers and excavators. Komatsu partnered with Skycatch, and claim to have created the world’s first machine-to-machine automated construction equipment. The Smart Construction initiative uses Skycatch autonomous aerial robots for data collection, point cloud maps with 1 cm accuracy, visual intelligence and advanced data analysis. Skycatch UAVs scan job sites to capture imagery and automatically generate accurate 3D site data. This data is then compared with 3D drawings of the site to automatically calculate the area and volume of earth to be moved. The results are transmitted as instructions to Smart Construction machinery for fully autonomous work on the site.



The company provides aerial imaging including 2D and 3D models to assist project managers, general contractors, site superintendents and engineers in tracking construction progress, measuring material stockpile volumes, improving environmental compliance, providing timely site surveys and real time mapping, improving safety and maintaining project schedules and budgets. Integrates with CAD and BIM software to facilitate collaboration and enhance real time decision-making.

They have a very interesting page on industry resources here. This lists 2016 conferences (all except one in the US, which was on insurance in London), a large number of software products, and drone insurance providers.



Their website doesn’t have a lot of information, but on this page they have some good videos, including the Sacramento Kings' stadium in California in the next item. I assume this means they provided the imaging for the software system under development there.



In August 2015, MIT Technology Review reported that drones were being used on the construction of the Sacramento Kings' stadium in California. Drone footage of progress on site was converted into a 3D model that could be compared to digital drawings to identify where progress was behind programme. The system was developed at the University of Illinois, where Mani Golparvar-Fard and his research team are developing GPS enabled quadcopters that will be computer-controlled to fully automate data collection, analysis and reporting of progress on the construction site. They have also developed a way for these robots to install cameras on elements of the site automatically.

In order to test and develop their system, the researchers were granted access to several construction sites around the U.S. being operated by Zachry Construction and Turner Construction, including their Sacramento Kings project. The University granted access to a current residence hall construction site, there is a video that shows the project on their campus at Urbana-Champaign.

Their system works this way: the quadcopters take photos and videos of the construction site, guided by a cloud-based computer program that can direct them to the rights spots, resulting in automatic data collection. The activities of the aerial robots are fully autonomous, including take off, navigation, landing and charging. The captured images and videos are then used to create an actual 3D model of the site under construction. The system compares this automatically generated 3D model to the as-designed 4D (3D plus time) Building Information Model, resulting in more frequent and complete progress monitoring information. The system also autonomously mounts battery-operated and WiFi-enabled surveillance cameras on different elements of the site to automatically capture videos of ongoing construction operations. Once the data is captured and transferred to the cloud, the system automatically detects and tracks workers and equipment in real time from the video feeds and categorizes activities of the resources automatically. The progress and activity monitoring results are visualized in a web-based, 4D augmented reality (D4AR) environment—a representation of the construction site in 4D with additional performance information superimposed on it. These D4AR models can also be made available to construction professionals through smartphones and tablets



Christian Eschmann is a researcher at the Fraunhofer Institute for Non-Destructive Testing IZFP in Saarbrücken, Germany, where he develops and adapts micro-aircraft for building inspections: “For a 20 by 80 meter wide façade, a test engineer needs about two to three days. Our octocopter (eight motors) needs three to four hours for this.” Cracks and other flaws can be digitally photographed in high resolution. If necessary, the octocopter can also be equipped with a thermal imaging camera, to check things such as building insulation.

The image yield is high, a15-minute flight can result in up to 1,200 photos. On the computer, the individual images are combined to create an overall picture, and the resulting 2D and 3D data models illustrate the visually imageable condition of the building structure. In the future, there will be software to delete any superfluous images. A complete software suite is planned for the future, including damage recognition, image processing, a database and documentation, as well as the automation of all operations, including stitching of individual images and identification of crack patterns. The octocopter took to the air in 2011 for its first inspection. So far, it has needed to be controlled manually. Eschmann and his colleagues are currently (in 2014) working on navigation sensors which will control the flying robot in the future. Following a predetermined pattern, these sensors will steer the octocopter along the façades, floor by floor, from one side to the other.



The UK contractor used a drone for surveying to capture detailed images of the construction path. Apart from surveying, the drone came in useful following a 2014 road traffic accident when it was flown in to record the incident scene and examine how local traffic management was set up.


This is the second in an ongoing series of posts about technology trends in the building and construction industry. The first is here.
