The building is really only 24 stories high. The 13th floor was shipped back to the factory!

In the mid sixties, I was working for Noble Concrete, Inc., in Chamblee, Georgia. We sold and installed Post tensioning cables for heavy construction projects throughout the southeast. The cables are made up of 1/4 inch cold drawn steel wire from Japan and cut to the correct length, bundled two or more together for the designed size and wrapped in a lubricated paper at The Prescon Corporation in Corpus Christi, Texas. These cables are placed in the concrete forms at the proper height along the length of each beam and then after the concrete has cured to the proper strength stretched about 6 inches for every 100 feet of cable.

There are two common methods for stretching cables. Stranded cables use gripping fingers to hold the cables at the correct tension. With the 1/4 inch wire, a steel plate and collar is drilled with the required number of holes, one for each wire and a button is formed on the end of the wire to hold against the collars and plates at each end. The sizes of the plates are determined by the number of wires and the area required to prevent crushing the concrete.

The sizes of the plates are determined by the number of wires and the area required to prevent crushing the concrete. When the concrete has set for about three days, A hydraulic jack with a hole in the center is placed over a steel- threaded rod with a device on the end that fastens to the collar. A steel chair is inserted between the jack and the steel plate. The cables are then stretched to the proper elongation and monitored by gauges on the hydraulic pump. When the correct tension and elongation have been, obtain, two steel shims are slid into place between the collar and the steel plate, the jack, chair and rod are then removed.

I started working for Bill Noble, sometimes referred to as Wild Bill for reasons I will not go into at this time, in 1964. I had some drafting experience but not much else in the construction field. Bill said that he would teach me all that I needed to know. The first day he showed me the drafting board and laid out a job to start on and went into the other room saying just call when I had a question. Well I did have plenty of questions over the next few years. I learned a lot from Bill Noble and some things that at the time seemed trivial, such as not to wad up trash when you throw it into the trash can as it takes up too much room. I still practice that today.

As I grew more familiar with the construction business, I started doing estimates on jobs that we would bid on in the southeast and one of those jobs was the Plymouth Harbor R
