Now is the time for Mobile IT in Construction

It had a slow start, but recent advances mean the time is now right for an explosion in the use of mobile technology in construction.



The construction industry is often characterised as being slow to adopt modern technology – but to anyone familiar with the industry this is clearly not the case. If anything construction is better characterised as creative, innovative and quick to adopt any technology that reduces cost – including information technology and new forms of communication.  Construction was an early adopter of the Computer Bureaux services that appeared in the 1960’s, of telex and then fax machines, of two-way radios, computer aided design, mobile telephones and email.

Early problems with using IT on construction sites

There is one area of technology that made great inroads into other industries such as manufacturing, logistics and retail, but until recently has failed to gain a foothold in construction – which probably accounts for the industry’s unfair reputation – and that is the use of information technology for process control.

By “process control” I mean everything that is used to manage and control a production process. That includes things like measuring progress and the conformance of products to the specification as well as giving instructions to workers and managing the supply and storage of raw materials. Those functions apply just as much to a construction process as they do to a manufacturing one. However, while manufacturing rapidly moved away from paper-based process control from the 1970’s onwards, construction did not. Process control takes place on the shop floor and the shop floor for construction is the construction site. Therein lies the problem.

Early forms of IT used for process control required a fixed infrastructure (i.e. cables) which in turn required a structured environment. Most construction sites are constantly in flux with what structure there is developing slowly during the lifetime of the project. For most of the hundreds of companies that come together to work on a construction project the nature of the physical environment they are working in constantly changes. Few other industries have the problem of spoil heaps suddenly appearing in the middle of the shop floor.  Consequently IT in construction used to stop at the site gates and even years later it was confined to the site office.


Then came mobile IT - first in the form of wireless local area networks and then increasingly in the form of mobile data services like GPRS and 3G (prior to GPRS the data services were too slow to have much of an impact). These technologies promised to solve the infrastructure problem by removing the need for wired networks. However, they required an investment in hardware which in the early days was very expensive. It was also difficult to maintain adequate coverage. At the time most useful applications that ran on mobile devices required constant connectivity – partly because off-line storage on the devices was very limited. Mobile phone bandwidth was low and maintaining coverage on site using wireless LAN’s was notoriously difficult (remember the moving spoil heaps).

However, there was, and is, a much bigger problem - one that is due to a fundamental characteristic of the construction industry itself. Its significance is often overlooked by those from other disciplines (particularly IT ones) and it remains a major barrier to the widespread and effective use of mobile IT in construction today.  The problem is that construction is a project-centric industry.

The problem with "projects"

Being project-centric on its own would not be a problem – however construction is also prone to the dramatic variations in demand caused by economic cycles. During lean times construction work dries up and is slow to recover as an economy comes out of recession – “first in, last out” as those in construction put it. What this means is that successful construction companies keep their overheads to an absolute minimum. As far as possible everything is financed on a project-by-project basis. That way when the order book starts to dwindle they do fewer projects, but stay in business. Those construction companies that let their overheads grow during the good times go to the wall during the bad.


Occasionally even some established names make this mistake. Periods of prolonged economic growth like the one before the most recent recession can lead to complacency. When recession does hit there is then a desperate scramble to reduce overheads by shedding salaried staff, disposing of injudiciously acquired assets (typically the offices that came along with small mergers or acquisitions) and “restructuring” to streamline those overheads which are essential – mainly accounting, office IT and human resources.  The pain for those construction companies that survive this process (many do not) only serves to reinforce their need to take a project-centric approach.

The result is a kind of Darwinian selection. The successful construction companies that stay around are companies that are structured in a way that avoids overhead. What this means is that the adoption of site-based IT happens piece-meal. There is a preference for off-the-shelf or hired solutions and any investment has to be justified on a project-by-project basis. The first time that PC’s started to appear in construction site offices was when their cost fell to the point that they were no longer classed as a capital item. This gave project managers the freedom to buy them directly out of their individual project budgets.

This situation is frustrating for technology vendors. Instead of being able to sell their product or service once to a single construction company they effectively have to sell it again and again to individual projects. Construction companies often have no mechanism or budget for investing in a solution that would need to be recouped across multiple projects. Even when there is a desire to do so they will often face internal opposition from their own project managers.

This is because most construction companies charge projects for the provision of any internally managed resource, such as plant and equipment or IT. If a project manager is not convinced about the value of an IT solution – or if the benefit is to the company as a whole rather than to his individual project – then he will see it as an unnecessary cost.  This can prevent companies benefiting from economies of scale or volume licensing without a great deal of internal wrangling.

The irony is that this project-centric structure leads to problems that IT based process control could actually help to alleviate. Because projects are treated as self-contained ventures construction companies often have trouble spreading best practice and learning from past mistakes. It is widely recognised that projects often end up “re-inventing the wheel” because of a failure to recognise and communicate innovations from one project to another. In the past construction has often claimed that all projects are “one off” – and to a large extent they are. Not due to any inherent characteristic but because of the way that they are managed.

There is, however, light at the end of the tunnel. Two technological advances now make it possible to bypass the inherent problems of getting process control IT onto construction sites. The first is the consumerization of mobile IT and the second is the advent of Cloud Computing.

Falling mobile device costs

Consumerization has dramatically reduced the cost of mobile devices. For construction this has a really important effect – it puts them in the hands of site engineers. Once a device is seen as a standard site engineer’s tool then the problem of purchasing it for a specific project disappears. This has already happened with the use of mobile phones and laptop computers.
 

Site engineers play a vital role in developing the use of mobile IT in construction. They are well trained enough to understand the commercial realities of the industry, but are close enough to the site process to recognise the potential value of new technology.  They also tend to be young enough and perhaps inexperienced enough, to assume that things can be changed.
 
I remember a time when site engineers were pushing for laptops in the company I worked for because of the time saving they offered and the ability to do more work away from the office.  The chairman of the company described this as “laptopitis” and dismissed it as a desire for gadgets – insisting that he personally approve all laptop purchases. He was wrong to dismiss their value – but probably right at the time about the cost-benefit. Today, in most parts of the industry, a laptop is seen as an essential tool for a site engineer.

The same thing is now happening with smartphones and tablet computers. The first place that Apple iPads appeared in construction was at board meetings in the hands of directors as a status symbol. The second place they appeared was on site in the hands of site engineers as a tool.  The difference this time around is that the price has dropped so far that engineers are circumventing company purchase restrictions by bringing their own devices (BYOD) to work. They are also buying and even writing their own apps.

However, getting mobile IT hardware onto site is one thing, integrating its use into the construction process in a way that enhances productivity and performance across the company is quite another.  Most consumer applications are not specific to construction and do not provide for back-office integration. Truly useful applications need to be tailored to the construction process and able to exchange data with other company systems – such as document management, cost and design.

Developing these kinds of mobile applications is traditionally expensive –both in terms of up-front cost and with subsequent licensing. This is where Cloud Computing comes in and in particular two trends that are emerging from it – application platforms and “as-a-service” cost models. 

Cloud application development platforms

Application platforms simplify the development of new applications (and thus greatly reduce the cost) by providing pre-baked functionality – common building blocks that can be re-used to create new solutions.  They vary from simplistic drag-and-drop form builders to sophisticated platforms that are fully-fledged development environments that can support back-office integration and bespoke code. Typically they also provide a way to deploy and update applications onto mobile devices – in essence allowing the creation of a corporate app store with little IT or administrative overhead.  The MobiCloud platform developed as part of the EU project that COMIT is a partner of is an example of just such a platform – but there are others.


Some platforms, such as AppearIQ which is used as the basis for MobiCloud, use a “container” approach. This is particularly useful in a BYOD scenario. The platform creates a container on the mobile device within which multiple applications can be installed and run. Those applications all share the capability provided by the container. This can include access to device specific resources (such as a camera) or to solution specific functionality such as back-office integration.

The container isolates the applications from the specifics of the device, including the operating system, which means that exactly the same applications can run on any device for which a container has been developed. This is a major benefit with the current fragmentation of the mobile device market, with iOS, Android, Windows and now even Firefox all potentially competing in the same space.  The container also provides a degree of isolation for corporate applications if they are running on a personal device – again essential for BYOD.

Flexible Cost Models

The final piece of the puzzle is the increasing prevalence of “as-a-service” cost models. Platform as a Service (PaaS) and Software as a Service (SaaS) essentially come down to paying for what you use. Instead of paying a one-off licence fee to give a user access to a piece of software for ever as you might do for a CAD package or an operating system (and in the case of CAD software that might be thousands of pounds), you pay a monthly fee.

This form of charging is increasingly being used by software vendors, such as Microsoft or Adobe, to attract “casual” users – those people who only have an occasional or short-term need for their products and who do not want to buy a permanent licence. However, it is also ideally suited to the situation in construction where solutions may be deployed on a project-by-project basis. It potentially allows project managers to dynamically scale up or scale down the number of people using a mobile solution on a monthly basis, without having to commit to a large up-front cost. This will encourage those project managers that are not entirely convinced of the benefits to try it out. As one manager put it “Knowing that you will only pay for what you use suddenly makes the business case a whole lot more compelling”.

At the moment most Software-as-a-Service (SaaS) solutions are not quite as simple as that. Most have a minimum monthly subscription period which is typically 6 or 12 months. However, this is still a big improvement on large one-off per-user licence fees and it is likely that flexibility will grow as the market matures and volumes increase. 



Site Safety

There is one final issue that the construction industry needs to come to terms with in order to maximise the benefit of site-based mobile technology – safety. At the moment the fear of mobile devices leading to user distraction and an increased risk of accidents is limiting their use in many parts of the industry. This is a real and justified concern but one that can be tackled in a rational, evidence-based way. 

Mobile devices are a tool like any other and carry risks as well as providing benefit. The industry needs to develop a set of standards for how they can be used on site in a safe manner. COMIT is actively helping to work towards this and it will be the subject of future posts.
