Hanson Structural Precast confirmed our three truckloads of hollowcore concrete panels will arrive on Tuesday morning so we can start unloading (working) at 8:00 am. 

Bill Brown and his team are ready, and the weather looks perfect.

Completing the Steel

Larson Steel finished installing our steel columns and beams today.  Of course, this is a prerequisite to putting in the hollowcore concrete panels tomorrow.

We had to ensure there was always a three inch bearing surface on top of each beam.  This required moving some Nelson studs and trimming the ends of some beams.  We confirmed that our structural engineer, Innovative Structural Engineering, had verfied the conditions in each location where the steel beams were connected to either the concrete retaining walls, other steel beams, or steel columns.  Shane Lothrop confirmed each connection was acceptable.

Require 3 Inch Bearing Surface

The following photos show the conditions where we had to ensure there was a 3 inch bearing surface on the steel beams for the hollowocore concrete panels.

Nelson studs and W6x16 beam projecting into the 3 inch bearing surface for the hollowcore concrete panels.

This W10x12 drop beam needs to be moved so our stairs can be at least 36 inches wide.

Making the Final Changes

Both Pete Larson’s team and Bill Brown’s team worked to ensure that we were prepared to place the 50 hollowcore concrete panels tomorrow morning. (more…)
