Fiber optic sensor gauges concrete curing conditions, maturity

The LumiCon system from Ontario-based Aoms Technologies enables concrete producers and their customers to remotely collect continuous, distributed, and real-time temperature and moisture data from many job sites simultaneously. It helps users control concrete curing conditions; manage the maximum internal and differential temperature in mass concrete placements; and, measure concrete maturity versus time. Real-time information delivery eliminates the need for trips to job sites to collect data or samples for testing, which improves quality, minimizes delays and reduces on-site labor cost.

Survey prices the leading drains on construction productivity

A survey of nearly 600 construction professionals finds that time spent on non-optimal activities—fixing mistakes, scouting data and managing conflict resolution—accounts for $177.5 billion in labor costs per year, while rework stemming from miscommunication and inaccurate or inaccessible information will cost the U.S. industry $30 billion-plus in 2018. Management consultant FMI Corp., Raleigh, N.C., and construction productivity software developer PlanGrid, San Francisco, examine how teams spend their time on construction sites, communicate during projects, and leverage technology investments. From survey responses, they determine:

Infrastructure study findings spell gains for precast methods

Demand for precast concrete in infrastructure products is projected to increase 4.4 percent annually, to $2.4 billion by 2022, with growth fueled by the need to repair the nation’s aging network of bridges, highways, roads and railroad tracks; increased adoption of the method over traditional cast-in-place alternatives; and, efforts by the federal government to increase surface transportation investment.
