How Drone Data Improves Construction Project Management

Drones can be used to monitor construction progress over
time, inform project management and prevent projects from finishing late—and in 2018 their use on jobsites increased by nearly 240 percent. The construction industry, which includes glass and glazing subcontractors, is the fastest growing commercial
adopter of drone technology.

In the webinar “Managing Construction Projects with Drone Data,” held by ENR, DroneDeploy co-founder and CCO Jono Millin discussed the capabilities drone data provides project managers. According to Millin, drone use is increasing because it can be difficult for construction contractors to understand what is happening and changing
across large jobsites.

Millin said that construction companies typically adopt drone technology to create:
Photographs – Drones can take photographs of a jobsite from any angle. Drones can also be programmed to reuse the same flight pattern to take a photo from the exact same location as before, enhancing site progress tracking. However, photographs are limited and do not lend themselves to scientific measurements.

Orthomosaic Maps –These maps, created by overlapping several images, allow drone users to look at a bird’s-eye view of a jobsite and then zoom into a high-resolution photo of anywhere on the site. This feature gives users the ability to know where an issue is located specifically on the jobsite. Users can flip through previous maps to see how the jobsite has progressed over time.

3D Models – These models add an additional perspective as the building is erected. Users can see exactly what is happening on the site

CAD Overlays – This feature pulls blueprints, plans and design data
and overlays it on top of current images of the jobsite so that users can
see how the project’s current state compares to the plan.

The dronedata can improve key workflows throughout the construction
process, such as:

Virtual Design and Construction
– Drone data can be used to create point clouds for site surveys. Each
pixel within the image has an X, Y and Z value, allowing users to easily identify the location on the jobsite. This data can be integrated with building information modeling programs.

• Project Management – Drones can be used to document site progress,
see what was happening at any time during the project, automate reporting and keep stakeholders informed.

• Site Supervision – Site logistics and materials management can be made more efficient with drone data. General contractors can also use the data to manage subcontractors and monitor construction.

 

AGMT Continues Beta Testing

The Architectural Glass and Metal Technician (AGMT) certification program continued beta testing the knowledge-based (KBT) and performance-based (PBT) portions of its certification exam.  Team members spent a week in San Leandro, Calif., administering, grading and analyzing the latest versions of the KBT and PBT.

Twelve candidates were tested in both portions.  The participants ranged in age and experience, some in the very first years of their glazing careers and others with more than 35 years’ experience.

The test site and candidates provided constructive insight for the AGMT team, helping them understand both what is working and what could be improved.  Individual exam results met anticipated time and  performance targets—serving as validation that the exam is operating as designed, according to the release, which added that candidate feedback has been positive and encouraging, with many candidates saying that the exam is both fair and an accurate depiction real-world glazing tasks.

AGMT plans to beta test in other North America locations before officially rolling out the program.

Most “Supertalls” Ever Completed in 2018

Architects are designing taller buildings each year across the
globe. That trend was analyzed by the Council on Tall Buildings
and Urban Habitat (CTBUH) in its “2018 Tall Building Year
in Review.” There are currently 1,478 buildings in the world taller than 656 feet (200 meters). Of those buildings, 143 were completed in 2018, maintaining momentum from previous years.

Of the buildings completed in 2018, 88 were in China. The U.S. had the second-largest number of completions by country with 13. However, Asia led the world in tall building construction with 76 percent of the completions. Nineteen cities worldwide got a new tallest building in 2018.

The CTBUH classifies “supertall” buildings as those taller than 984 feet (300 meters). In 2018, 18 supertall buildings were completed. That’s the most ever completed in one year. The tallest was Citic Tower in Beijing, topping out at approximately 1,732 feet (528 meters).

The average height of the world’s 100 tallest buildings has grown since 2001 when the average height was approximately 928 feet (283 meters). In 2018, the average height was 1,250 feet (381 meters). Sixteen new buildings entered the tallest 100 buildings in 2018, up from 14
in 2017.
