Technology is something we tend to take for granted, yet every industry
is moving at the speed of technology. This is particularly true of the
construction industry, which itself has undergone a metamorphosis driven
by technology. Today, construction companies are measured by the speed
and accuracy they employ in completing their various contracts. On many
job sites, you may likely see a construction foreman using a laptop
computer to review job progress, communicate with the client and the
home office, keep work-related notes including any changes to the
project, monitor inventories, review payroll, and control costs.
It has been said that "time is money," and technology is helping
construction companies conserve time by increasing accuracy and adding
to bottom line profit margins through the implementation of cost and
quality controls.
Job site safety is also impacted by technology. Recently, there has been
a move to implement safety technology to protect workers. More
significant is the effort to protect the job site itself using the
latest in sensor technology, utilizing a point cloud, a set of data
points in a three-dimensional coordinate system.
In a three-dimensional coordinate system, these points are usually
defined by X, Y, and Z coordinates, and often are intended to represent
the external surface of an object. Point clouds may be created by 3D
scanners to monitor the construction site for fire, water, and mold
damage. These sensor systems offer both alerts and detailed analysis to
help reduce long-term risk. The end result of this use of technology has
been cost savings through reductions in construction site mishaps and
building damage from natural causes.
Consider some of the latest in technology applications for the
construction industry. The first is Building Information Modeling (BIM),
a 3D model-based technology process for creating and managing project
information. This technology has been most associated with the design
process. However, BIM can be used before, during, and after
construction.
A 3D BIM model is a digital description of every aspect of the build,
and objects embedded in the model can be linked to related information
such as photos, specifications, or manuals. BIM technology can benefit
construction professionals by helping them create better design plans,
produce faster results, and stay within budget, leading to less risk,
more profit and better, faster implementation.
Another example of technology application in construction is the use of
3D Laser Scanners that capture a physical object's exact size and shape
and input the data into a computer as a digital 3-dimensional
representation, again utilizing point clouds. Once completed, the point
cloud is outputted to a computer as a data file. This point cloud
represents the set of points that the device has measured. As the output
of 3D scanning processes, point clouds are used for many purposes,
including to create 3D Computer
Aided Design models for any number of visualization, animation,
renderin,g and customized applications including those used for
construction.
The construction trades are also making good use of drones or Unmanned
Aerial Vehicles. In the simplest terms, a drone is a pilotless aircraft
whose flight path can be automated using a predetermined route or
manually controlled using a mobile device or remote control. Drones help
construction professionals conduct site surveys and can be used to
track project progress in real-time by generating aerial photos, maps,
and 3D images. In addition to monitoring activity at the job site,
drones can be used to improve worksite safety and overall productivity.
Many construction firms are employing the use of Virtual Reality and
Augmented Reality Technology (VR/AR) as well. VR/AR technology enhances
collaboration among project stakeholders before building begins. VR/AR
technology allows construction teams to detect problems ahead of time
and to avoid costly mistakes by improving job site safety, allowing site
managers and workers to model job site conditions without subjecting
them to actual safety hazards.
In the greater Grand Rapids area, construction companies are making good
use of the available technology to control costs and improve customer
satisfaction.
Calvin College alumnus Eric Timmer is the Director of Virtual Design and Construction for Allied Mechanical Services, Inc.
As the focal point of his job, Eric uses tech to determine the best
ways and methods that can be used to build a structure. Principally,
Eric uses 3D Building Information Modeling, along with the data outputs
or "point clouds" from 3D laser scanners. Utilizing BIM allows him to
virtually create a full model of any building or project well in advance
of construction.
3D BIM allows Eric to determine all the components that will be needed
to complete a particular project and the use of 3D laser scanner
provides an accurate look at existing conditions within a site
structure, including mechanical and electrical systems. “Technology is
changing rapidly and Allied Mechanical is on the cutting edge on what
the latest tools can do,” says Timmer.
Brian C. Knapp, creative director for Externa CGI 3D,
a GR CGI firm, uses animation and virtual reality to plan for
construction projects. “Utilizing 3D animation and drone aerial footage,
Externa CGI is able to produce detailed 360-degree footage of any room,
allowing consumers to virtually navigate a home or office prior to
construction or purchase,” says Knapp.
This 3D technology can even adjust the lighting levels within a
particular space to reflect the time of day in addition to the sun
placement in the sky and any shadows. This allows for a more natural
view of the space that can help facilitate better planning and decision
making in advance, resulting in the potential for enhanced satisfaction
of the construction on the part of both owners and tenants. One person
who engaged in a virtual demo of this technology told of being
“teleported” to a waterfront condo where she could enjoy not only the
view but also move virtual furniture.
Steve Datema, project manager with Triangle Associates Inc.,
utilizes much of the aforementioned tech on a daily basis “Construction
technology has changed more in the last five years than in the previous
50,” says Datema. "At Triangle Associates, drone technology is used to
remotely conduct a site investigation. Doing the site investigation via
drone helps keep costs down by not putting any individual in harm's way
and also allows for maximum efficiency."
For existing buildings that are being remodeled, repurposed, or
refurbished, Datema cites the use of 3D design packages that allow him
to see building composition and how any of the existing steel,
electrical, or mechanicals may overlap and pose a problem.
The effect of technology on the construction trades is wide-ranging and
dramatic in its ability to improve building quality, increase
efficiency, save time and money, and make projects more efficient,
accurate, and safer for workers.
Construction companies are no longer simply the assemblers of the bricks
and mortar that go into a building; they are serving to preserve and
expand the use of technology by building better buildings and managing
better projects. By using technology and applying it to its best use
every day, the construction industry is making life safer and more
productive.
