1144 Fifteenth Update #7

DenverInfill recently had a unique opportunity to go “inside the infill” and check out 1144 Fifteenth Street from inside the fence, thanks to Dave Klebba of Hines!

It has been a while since we have seen a building over 600 feet under construction in Denver. That being said, the foundation and early construction processes are going to be a bit different. So what exactly is going on in the pictures below? Workers are drilling foundation piers that will go down over 100 feet. This will anchor the foundation which will get poured in the coming weeks. The large tubes of rebar, on the left, will get set in the hole which will be filled to the top with concrete.

Safety, with a hole that deep, is an obvious concern. Workers are harnessed to a slab of solid concrete to keep them from accidentally falling in a hole more than 10-stories deep. Also, check out the size of the drill bits being used!

1144 Fifteenth Street is making very quick progress and should be to the ground level by February. Then, it’s 12-floors of concrete and 28 floors of steel!

    Great that you’ve been invited inside the fence, Ryan! In the first photo, on the left, that dirt spinning off the drill bit is called “Denver Blue,” the typical blue shale that’s considered bedrock under Downtown buildings.

    Very cool… I would love to see that soil profile!

    Why so few updates these days, Ryan? I only ask because I really enjoy the posts and pictures. Hope to see more soon!

      Both Ryan and I have been super swamped with various work and personal things that have come up in the past couple of months that have kept us from posting as much as we’d love to. Hopefully we’ll have more time for posts soon!

        Totally understand. Not trying to complain. Just an impatient fan of this site.

        I’ve followed this wonderful blog for at least seven years. Hundreds of great reports, enlightening us all about the changing face of Denver. This current pause in posts reminds us how we can get spoiled, expecting continuous new stories, as an entitlement.

        Ken’s websites are continuously updated by his voluntary, unpaid work. Ryan’s hundreds of reports are voluntary. Maybe others should step forward, to help carry the load.

        Meanwhile, Ken says there are “dozens” of new projects underway, which we all want to learn about.

        Thanks for the update, Ken. You and Ryan have fans that love hearing about the new updates around Denver. Looking forward to having you both back soon!
