With at least $9.5 billion in development projects in the downtown pipeline over the next decade, construction industry leaders are under pressure to find enough qualified workers to ensure the work gets off the ground.
Skillman, the 11th-largest Indy-area construction contractor, is among a handful of local construction firms to give their employees a direct stake in operations and profits.

Engineering
researchers at Purdue
University have come up with sensors that can
determine concrete strength onsite in real-time, and they re testing
it right on campus. The hope is that the technology will help
builders speed up their construction timelines safely.
According to a
campus
article, concrete mix designs are tested offsite for compressive strength before their use in a construction
project. Once the testing is done and the mixes vetted for use, they
can t be changed without additional testing. The new sensors would
eliminate the need for offsite testing by enabling contractors to
verify the concrete s maturity right on the jobsite.

Dive Brief:
Purdue University engineers have developed sensors that could safely speed up a construction timeline by determining concrete strength directly on site in real time.
Typically, concrete mix designs require testing before implementation in a construction project. Once those mixes have been vetted for use, the mix design cannot be altered without additional offsite testing. The new technology would remove the need for extensive offsite testing by allowing construction contractors to verify the concrete’s maturity on site.
“Our sensors could help make better data-driven decisions to determine the construction schedule and improve the quality of concrete construction,” said Luna Lu, Purdue’s American Concrete Pavement Assoc
