Polygon’s Rob Sullivan, aka Rob on the Job, provides a “day in the life” tour of a construction site in Allison, Maryland. As a part of his workday, Rob focuses on maintaining temperature and humidity control while installing finished material in a six-story building. Control achieved using four H.C.U.s (Hybrid Desiccate and Refrigerate Units) is particularly effective given the day’s high relative humidity of about 90% and temperature of around 67 degrees. Rob checks the gear, provides a glimpse into installing ACU 6000 CFED units, and discusses on-site safety measures. He concludes his video by thanking viewers for joining him and promising future on-the-job adventures.

Hey guys, Rob on the job. Thanks for joining me. We're gonna do a day in the life and see what you think. Hey, guys. So Rob here on the job. We're at a construction site in Allison, Maryland. And set up to the climate controlled. I just want to give you a give you a visual of what's going on. This is an active site. A lot of safety regulations and rules to get on-site and just figured I'd show you figure out a little bit. So we've been tasked with providing a little bit of temperature relative humidity control in the space during construction, during install of finished material. So it's a six story building. And we install at this point four H. C. U. S. Hybrid desiccate and refrigerate units outside today. Our conditions are about ninety percent relative humidity. Sixty seven degrees, e sixty five to sixty seven, and we're going to run through a little bit of performance check on the gear. Bridal install and look here for ACU six thousand CFED units while they get to single door see that they're currently working on it, closing the face, activate what they want to go with the safe drag app. Okay. So that concludes the Rob on the job adventure. So thanks joining me, and we'll see you next time.

Bell partnership lets Hitachi target the classes that make up roughly 90% of the North American ADT market

Bell partnership lets Hitachi target the classes that make up roughly 90% of the North American ADT market

Through a collaboration with Bell Equipment, Hitachi Construction Machinery Americas plans to add three articulated dump trucks: the ZD30, ZD45 and ZD50. The launch is scheduled for early summer 2027, and Hitachi dealers in the United States and Canada will support the trucks. Ranging from 30 to 50 tons, the models put Hitachi in the equipment classes that make up roughly 90% of the North American ADT market. The lineup gives contractors a single dealer network for excavators, wheel loaders and articulated dump trucks.

  • 01Hitachi's ZD30, ZD45, ZD50 articulated trucks launch early summer 2027 and address size classes representing about 90% of North American ADT demand
  • 02Bell Equipment, with over 26 years in the North American ADT market, manufactures the trucks while Hitachi dealers distribute and support them across the U.S. and Canada
  • 03The partnership lets Hitachi dealers quote excavators, wheel loaders, and ADTs from one network, expanding their offering.

Hover 3D roof measurements now flow straight into Trussi roofing estimates

Hover 3D roof measurements now flow straight into Trussi roofing estimates

Trussi, built inside Shamrock Roofing and Construction, imports Hover 3D measurements into job records and estimate fields. Hover reports bill to the contractor’s own Hover account at existing pricing, with no markup. One phone capture can also support exterior quotes in multi-trade workflows.

  • 01Hover reports bill to the contractor's own Hover account at existing prices, with no reseller markup.
  • 02One smartphone capture can feed both a roof estimate and a siding, window, door and trim takeoff, which matters most for contractors who sell more than one exterior trade.

Procore expands NVIDIA collaboration on construction digital twins

Procore expands NVIDIA collaboration on construction digital twins

Procore has announced closed-beta digital twin capabilities, powered by NVIDIA Omniverse libraries, that link 3D models to procurement and schedule data and to DroneDeploy site captures. How much they pay off likely depends on how current each contractor's schedule and procurement records are, especially on data center megaprojects.

  • 01Procore’s NVIDIA twin links model to schedule and procurement data, showing how a late delivery can ripple into downstream work.
  • 02A delay simulation is only as good as the delivery dates behind it: projects that track procurement outside Procore would get the 3D model with less of the ripple analysis.
  • 03Investing.com says Commissioning and an IBM Maximo integration are in beta; they could extend the twin past handover as closed beta expands.
