Construction Technology ments can be placed precisely using “to- tal stations” — highly accurate GPS or laser positioning. The benefits include improved accuracy, reduced waste, increased safety, and less manpower. 6 Facilities Management Software Enhanced software allows districts to use building information modeling (BIM) to track warranties, main- tenance items, system use, security, room assignments, and more. This information helps districts stay on top of their largest assets and significant expense points. And now, the instant accessibility via mobile devices allows the maintenance department to make more timely and informed decisions. 7 Digital Plans and 3-D Content Districts and construction personnel can access digital plans and 3-D content from the cloud through tablets and smart- phones to gain real-time information for making decisions in the field. When used properly, digital plans offer the following advantages during construction: • The most current plans are always available. • Updates are instantly shared, in- cluding construction bulletins, photos, addenda, and scope changes. • District personnel, subcontrac- tors, and suppliers can regularly access 3-D views in construction documents to communicate design intent, increas- ing communication effectiveness and proper delivery. • Digital plans allow more use of color without expensive color printing. They can zoom in and out of objects and even digitally measure items or share comments on specific recom- mendations right on the plans. • Digital plans display punch lists with items tagged for action directly on the plans. essentials | | summer summer 2019 2019 30 tk essentials 8 QR Codes and Barcoded Items Construction and project items may have QR codes or barcodes relating to an object ID in the BIM. Items are scanned as they are installed, which automatically updates the BIM to reflect progress. This capability allows more effective and efficient tracking during the construction project. Moreover, the tracking can trigger additional purchases for the next stage of work for more effective scheduling. The tracking codes can also link to user manuals, warranty information, equipment invoices, and related his- torical correspondence. 9 Laser Scanning Laser scanning captures an accurate representation of existing buildings and systems, which can then be modeled, or new objects “clashed” against for proper system coordination. This technology has a variety of uses and can allow the district to visualize existing conditions beyond the results of photos and taped measurements. Perhaps the greatest benefit of laser scanning throughout the construction process is the ability to compare the installed progress with the digital mod- el to evaluate accuracy, allowing for the adjustment of future prefabricated items before delivery and installation, while providing another accurate method of tracking the percentage of completion. ROBERT KOEHLER MATT MCGREGOR 10 Automated Bricklaying Automated instal- lation of masonry significantly reduces labor cost. Some automated brick systems can lay 3,000 bricks a day, compared with a construction worker’s average of 500. With some systems, the conveyor belt, mortar pump, and robotic arm combine with a worker who feeds the bricks into the machine. A second worker smooths over any excess joint mortar. As mason professionals retire, we can expect automated bricklaying to become more mainstream in a field that already sees a worker shortage. Take the Next Steps Becoming aware of technology’s effect on the construction industry can be a great first step as a dis- trict considers its next construction project. These 10 technologies will increasingly affect how that district plans, designs, constructs, and uses its buildings. n ROBERT KOEHLER AND MATT MCGREGOR are project architects at Hoffman Planning, Design & Construction Inc. in Appleton, WI.
