Topping Out

We have reached the point of "topping out" at 1101! The roof is being poured and with that milestone achieved, one of the biggest risks in construction is behind us. 1101 is built with what is known as post tensioned concrete slabs...why, you may ask, is that important? Well, for the future homeowner at 1101, they should consider this from the Post Tensioning Institute:

Post-Tensioned reinforcing has been used for many decades in bridges, elevated slabs (parking garages and residential or commercial buildings), residential foundations, walls, and columns. The use of post-tensioned reinforcing can result in thinner concrete sections, longer spans between supports, stiffer walls to resist lateral loads, and stiffer foundations to resist the effects of shrinking and swelling soils. The additional advantage of putting the concrete into compression can be used to construct slabs and walls that have fewer visible cracks that can allow the passage of moisture and termites.

In other words, this is good! It is, however, a tricky and sometimes time consuming process. Structural engineers are intimately involved in the process working side by side with the builder. Numerous samples of the concrete and its compression strength are taken through the course of the buildng to ensure the highest quality.

In a future post we will discuss the significance of the roof at 1101 - yes, it does a lot more than just keep the rain off our heads! But for now, let's raise a glass to Solomon Builders and congratulate them on the great work in achieving this milestone!

With topping out achieved, the interior work begins in earnest. You will see the windows starting to be installed on the lower level as the steel studs and drywall march up through each floor. Masonry and stucco work will begin on the exterior as the interior buzzes with the activity of plumbers, electricians, dry-wallers and all the trades needed to convert this concrete "skeleton" into an impressive luxury condominium community. The split-faced block is already going in on the ground levels and it is a beautiful product with a lot of depth and grain. In the end, 1101 will be a sturdy, handsome addition to the neighborhood...one that anybody would be proud to call "home."
