Questions regarding the erection of this 1,000-foot tower in Miami may have been asked when a similar project - a 1,500-foot tower in Deland, Florida - was also captured in time lapse intervals.

Please click here to see the Q&As. If your question wasn't addressed, please submit it to info@wirelessestimator.com

Are the wind and weight load equally balanced and distributed on all three candelabra structures?  If not, how much variance can there be before the entire tower is compromised? I love watching the progress of this project.  It is fascinating.

--A Texas Native

What type of antenna is the one on the right of the tower? Is it a special DTV antenna?

--Paul Whalen

Why is the candelabra different sizes? Wouldn't it be easier to have them all the same size?

--Abe Fisher, Cranford, New Jersey

----- The three candelabra arms are all the same size; the antenna mounting frames are not, but are designed to accommodate the antenna's height requirement.

The antenna seen on the right is not an antenna, but is a dummy pole. Some engineers scoff at this term and would much rather call it a load equalizing substitute, but that nomenclature has never caught on in the field, nor will it.

This faux compensatory communications column allows for equally distributed loads on the tower for proper balance.

I've been glued to this construction since it started. What is the purpose of the second lifting device on the top of the tower? Why can't the gin pole put on the antennas?
--Andrew McGuiness, Charleston, SC

----- The tower-top crane is required to be able to swing the three candelabra arms in place, a mobility that the gin pole can't accomplish.

The track pole lifting system will raise the candelabra mounts - weighing approximately 20-tons each -  and then the hydraulically operated crane (the equipment sits in the yellow platform box at the left of the top of the tower) will install them on the face of the tower approximately 60-feet from the top.

Prior to that, pipe knee braces (sometimes called kickers)  will be installed on the tower to provide additional structural support.

Candelabra sections are oftentimes picked with the knee braces already attached. However, the extraordinary weight of this candelabra, designed to meet the South Florida building code, would not allow the crane to pick it safely, and the bracing had to be installed prior to the candelabra pick. Sometimes it will take up to five hours or more to safely install one candelabra section.

A lattice section will be placed on each candelabra which will support the antenna.

There will be a 50-foot separation between antennas.
