See how real-time concrete data monitoring could transform our job site Premier Concrete Systems and Wohlsen Construction Company partner with Converge

he Sunrise Senior Liv - ing Frankl in Lakes project is your typical job site by every appearance. The 82-unit steel frame facility consists of two floors above a basement parking garage and spans 110,000 s/f. But there’s more to Franklin Lakes than meets the eye. Beneath the surface, a network of sensors is uploading concrete tempera - ture and maturity data to the cloud in real-time. At Franklin Lakes, Pre - mier Concrete Systems and Wohlsen Construction Com - pany partnered with Con - verge, a green construction T

sensors at Franklin Lakes, Wohlsen sees a compelling opportunity to drive efficiency and sustainability across the entire portfolio. Ons i t e in New Jer sey , Wohlsen project engineer Ge - rardo Reyes embedded 4 of Con - verge's sensors in each 12-inch pour, for a total of four sensors across the superstructure. Ev - ery sensor has a QR code, which is scanned into Converge’s ConcreteDNA software system. “The sensors were very easy to set up and use and the sup - port we had from Converge was excellent,” said Reyes. Each sensor takes continuous

concrete temperature readings after a pour. A Bluetooth- enabled device with the Con - verge app can collect the sen - sor data wirelessly and trans - mit it to the cloud for Converge to process and return real-time concrete strength information. The platform can also be con - figured to notify devices when - ever the concrete strength reaches key milestones. Premier Concrete Systems, was eagerly waiting for con - crete in the basement to meet 75% maturity in order to remove shoring and install plumbing and electrical. Us - ing conventional concrete testing methods, Reyes would receive actionable updates on concrete strength from a laboratory once every seven days. Thanks to Converge’s system sensors, Reyes gath - ered daily readings for the Franklin Lakes site in twenty minutes and shared them immediately with Premier, allowing them to act without delay or risk.“With this kind of technology, we’re able to in - crease efficiency exponentially because we can act precisely when we want to,” said Tony Escada of Premier Concrete. Wohlsen’s partnership with Converge is also a success sto - ry in virtual and international collaboration in a post-COVID world. Wohlsen Construction project executive, Conor Evans first learned of Converge from an ENR article in the January 29, 2020 edition. Within two weeks, Evans had engaged the London-based company to dispatch sensors to the Frank - lin Lakes site in New Jersey. Wohlsen unexpectedly began construction a week ahead of schedule. Responding dynami - cally to the change of schedule, the Converge customer service team acted quickly, and across a five-hour time difference, to deliver the sensors in time for the first pour and to coordinate sensor calibration from over - seas. During the worldwide disruption from COVID-19, Converge, Wohlsen, and Pre - mier continued to successfully collaborate across the Atlantic via video conference. Al though these c i rcum - stances deviated slightly from Converge’s typical calibration workflow, the sensors provided notable accuracy at the 7- and 28-day mark. Calibrating ac - cording to the standard pro - cedure would have improved accuracy further. MAREJ
