There is no alternative to digitisation. Even on the building site. Construction needs to catch up.
Digitisation is about businesses encountering connected systems at every link in the value chain. It is about working with tools and practices based on information and communication technology.
Digital technologies are no longer mere tools to help companies do the same things a bit better. Instead, they fundamentally change the way business is done. Digitization permeates every part of every company: multinationals and midcaps, all-rounders and specialists alike.
Companies face the challenge of deciding which approaches suit them best and how they can be implemented. Ignoring digitisation entirely is not one of the options. Recent developments in construction and other branches of industry show that there is no stopping the megatrend toward digitisation.
“Boom times, skilled labour shortages, higher job complexity and ever-increasing client expectations have meant the civil construction industry is increasingly looking toward technology to improve productivity, solve skills and resource issues and improve profitability.”
INTERNATIONAL STUDIES, such as the McKinsey Global Institute Industry Digitisation Index, show that the construction industry has one of the lowest rates of technology implementation and sits well behind industries like mining and manufacturing – ranking 15 out of 16.
The opportunity exists for significant gains in productivity and efficiency via the adoption of technology and through digitisation of construction processes.
Many of the issues that are regularly seen can be mitigated or eliminated through digitisation and empowering people onsite. The engineering and construction industries have made significant progress in the past 10 years with digital design, however we are only at the beginning of a journey which will, in our lifetimes, radically change the way our industry operates.
Globally the divide continues to widen between constructing using traditional techniques (2D plans) and constructing via technology using and machine control systems. Each year the technology advances further, becomes more powerful, generates higher levels of productivity and is easier to implement for business managers and staff, as well as being more affordable in terms of its return on investment.
The construction industry is following global trends with the rapid adoption of machine control technology.“
The tight tolerances on many of these projects necessitate the use of machine control as it’s simply not possible to meet the requirements without it.
On smaller projects, where the tolerances aren’t generally as tight, the productivity benefits, savings through minimising rework and ability to self-manage the construction process are the main drivers behind the rapid adoption of the technology.
Within the construction industry most business owners list a lack of skilled staff in their top three current business challenges. Increasingly contractors are looking toward technology to help solve some of those challenges. Younger people entering the industry have grown up in a digital world and easily embrace new technology and working in a digital environment.
Companies embracing a digital construction process are able to take lesser skilled operators and make them highly productive in a short period of time and therefore gain a competitive advantage. This is a way of not only coping with labour and skills shortages but can also assist with retention of key staff and providing career development and opportunity.
The construction industry has also become smarter in the use of GPS rovers, robotics and drones, which enable the contractor to easily quantify their work on measure and value contracts to ensure they get paid for the work completed. By moving to a digital process the contractor doesn’t have to rely on an often inaccurate schedule of quantities or load counts.
Tools are now readily available for contractors to manage all their set-out, as-builts, volumes and quantities on projects with full reporting in the field. This allows contractors to manage the entire project and make decisions without being reliant on external surveyors and engineers.
At the same time design software has evolved significantly over the past 15 years making the production of 3D models a relatively easy task. Whilst the use of 3D models and machine control technology is now commonplace in New Zealand there are benefits to all parties (clients, designers and contractors) through full digitisation which are not yet being fully realised.
The client and contractor stand to benefit the most in moving to a digital workflow as contractors are able to deliver projects more cost effectively, to higher construction tolerances and quality in a shorter timeframe.
The industry would benefit further if 3D models and designs became integral parts of the contract documentation for use by the contractor. This adds a higher level of accountability on the designers to ensure their design is correct which should be the ultimate goal of any efficient industry.
This digital construction process is well established internationally with machine control and construction survey technology a prerequisite on most major projects. Whilst it’s not mandated in New Zealand, it’s commonplace and those trends will continue.
For people working in the construction industry this shift in the way we construct brings with it exciting opportunities. Our industry is often not seen as the most exciting choice for younger people despite the excellent career and opportunities.
The trend toward digitisation allows people to put themselves at the cutting edge of the industry and keep up with the latest developments in technology. I truly believe it is something we, as an industry, should be actively promoting when trying to attract younger people into construction.
Looking Into The Future
In building construction, BIM (Building information Modelling) is re-shaping the way we construct and maintain buildings and facilities. Like building construction, the civil construction process is complex with decisions being made on a daily, if not hourly, basis which can affect the construction process.
The BIM process empowers people onsite by putting information and decision-making tools in their hands. Many of the learnings from the BIM process are transferable into civil construction and as the digitisation of the industry accelerates we can expect to see the way we construct and manage assets evolve with it.
Looking further ahead into the future, and on a larger scale, we are seeing the concept of digital cities evolve with CIM (City Information Modelling). CIM is a process whereby every asset above and below ground is precisely mapped and attributed including all the structures, material types, services etc and can then be used by a wide range of industries including construction, facilities management, emergency services, planning and design, etc.
In a challenging labour market, contractors are increasingly looking to use technology to increase productivity, resolve skills and resources issues and gain a competitive edge. In the digital world we now live in, there is significant scope for the industry to benefit and gain efficiencies through the digitisation of our construction processes.
We find ourselves in exciting times, on the brink of realising significant change in the way the industry constructs and delivers projects through digitisation.
