June has been a productive month with favorable weather for construction activities in our alpine setting. With the snow fully melted and Summer in full bloom, the picturesque green mountains set against the pristine blue sky create a breathtaking backdrop. Notable achievements this month involve the successful completion of the mat slab, as well as the installation of columns and shear walls at the Garage Level of Building C. Progress is evident with ongoing excavation at Building B, which has now reached its final base depth. Meanwhile, shoring operations have commenced at the western end of Building A, with the installation of thirty-foot-long sheet piles driven into the ground.
Scroll down to view the progress from the sequential photos below:
Above: Installation of the mat slab rebar grid – June 13, 2024. This complex structure was installed over the base concrete slab, which was completed in May. The entire garage floor will function as one massive footing for Building C.

To achieve this massive pour, crews started at about 4 AM and ran 227 continuous concrete trucks for over 8 hours.

Building B will have three levels below the driveway supported by the shoring wall. The next steps will be gravel placement and leveling, a base concrete slab, and then a massive mat slab foundation.

Once all of the support columns and shear walls are complete, crews can begin the assembly of horizontal forms for installation of the post-tension concrete slab of Level One.
