Digitization in the construction industry

ready making good use of such electronic portals.
French company Saint Gobain is currently rolling out a
new digital logistics concept in Germany. Its aim is to
enable building sites to be supplied 24 hours a day,
which in turn gives industry players the chance to or-
der materials for very specific points in time.
4. DRONES AND ROBOTS MOVE OUT OF
SCIENCE FICTION BOOKS AND INTO THE
FUTURE OF CONSTRUCTION
Construction projects are becoming ever more
complex. Equally, cost and time pressures are rising
and quality expectations increasing. In response, the
industry must find ways to reduce complexity and
costs, raise productivity and guarantee quality. The
good news? The tools are already there!
Alongside advance planning, surveying the build-
ing land is one of the most important tasks in any
construction project. 3D laser technology opens up
new possibilities in this context. 3D lasers not only
survey the land, but also very quickly identify water
pipes, sewers, phone lines, fiber optic cables and pow-
er lines. They capture all this data and feed it into dig-
ital planning tools that are immediately available to
the project manager. Drones are likewise already in
operation in the construction industry. They survey
the land, monitor large building sites and track the
progress of construction projects. Where buildings
have been completed, they also measure energy dissi-
pation.
Mobile cloud solutions are growing increasingly
important in the building trade. Studies show that
communication occupies as much as 90% of construc-
tion project managers' time. When problems arise – if
different players don't have the same information or
can't access the data, for instance – the entire process
can quickly grind to a halt. As things stand, most build-
ing firms still use project management programs that
are installed on desktop PCs. Yet cloud-based and mo-
bile solutions have the tremendous advantage of being
available wherever you happen to be working. Here
again, it becomes apparent how much sense it makes
to work on site with mobile devices.
"Hadrian", the brainchild of Australian enterprise
Fastbrick Robotics, showcases what construction ro-
bots are already capable of doing. Buildings that would
have taken human brick layers several weeks to erect
can now be completed by Hadrian in 48 hours. The ro-
purchases and around 10% in the case of online auc-
tions, for example. Swedish construction outfit Skans-
ka does things differently, though, and already handles
about half of its material sourcing via a digital plat-
form. Tool manufacturer Hilti has outsourced all its
indirect procurement processes and now commissions
an external procurement management team to trawl
through catalogs, online shops and other electronic
platforms in search of the most attractive prices and
offerings.
3. SMART BUILDING SITE LOGISTICS
HOLDS OUT POTENTIAL FOR OPTIMIZATION
Construction workers devote only about 30% of their
working time to their principal activity. The remaining
70% is taken up by running errands, transporting ma-
terials, cleaning up, rearranging the building site and
looking for materials and equipment. It is therefore
perfectly understandable that many businesses see a
need for optimization.
This is where digital technology can help. Supply
soware, for example, can be used to ensure that mate-
rials are delivered to the site just in time, i.e. precisely
when they are needed. Storage and rearrangement
work can be minimized as a result. Similarly, smart,
connected construction machinery helps optimize ca-
pacity utilization for workers and construction vehicles
alike. Via the internet of things, excavators can call a
free truck whenever one is required. In return, the
truck can inquire when and where what material is
needed. Construction workers have fewer journeys to
make and less coordination work, so less time is spent
traveling and looking for things. Conversely this sce-
nario can only work if digital devices are standard issue
on the building site.
Apps are already on the market that use GPS or other
navigation technologies to locate products and materi-
als. RFID

technology in particular opens up all kinds of
possibilities. Products fitted with this technology can be
identified using electromagnetic fields. They can also be
registered and scanned, which simplifies the hiring of
equipment and creates transparency regarding the
whereabouts of machinery and materials on the build-
ing site. It is even possible to fit freshly laid concrete
surfaces with RFID technology in order to analyze them.
Soware solutions that help building firms with ev-
ery aspect of the logistical chain are also available.
Building material manufacturers in particular are al-
