Baltimore's Grand Prix Race Gets Additional Cell Coverage on the Roof of the Baltimore Convention Center.
Sheets of plywood get rigged to go up to protect the rubber roof of the convention center. The plywood gives us a safe place to land our job materials without damaging the roof.
The roof of the convention center back dropped by the Baltimore skyline.
Dan Mann, Dan McHugh, Rey Reyes and Gene Young, making up one fourth of our crew today, pose for pre-lift photos.
The area around the mobile crane is cordoned off for safety.
A metal basket carries loose supplies up top.
Steel framework called "sleds", which will support the cellular antennas, are hoisted up and over the lower roof.
Chad Brown and Gary rig the cable reel. The cable is coaxial cable just like what is hooked to your TV, only bigger. It will carry the radio signal to and from the antennas so you can talk,text and send pictures during the Baltimore Grand Prix Race.
This reel weighs about 600 lbs.
Three of these reels have to go up to connect the cell site.
These antennas will be mounted on pipes and then attached to the "sled" and be pointed in the desired direction of the coverage area needed.
The token artsy shot.

Construction of the cell site on the roof is just getting started, but the Boom truck can't stick around hogging up the street, so we pack it up and Len Davis, our truck driver extraordinaire, wheels it back to our shop in Woodbine, Md.
I, on the other hand, must go to M&T Bank Stadium to take care of some safety training for our workforce there. Another day, another dollar.

Monopole Tower Stack - Baltimore, Maryland
The 1st section arrives on site.
Anchor bolts in the caisson
Crane lifts the 1st section off the truck.
1st section rigged & lifted into position.
Holes are carefully lined up with the anchor bolts.
Nuts are tightened with a special wrench and a sledge hammer.
Smoothing things out for a better fit.
Climber goes up to de-rig the crane and await the next section.
Removing the rigging.
Next section lifted for inspection.
Climber awaits the next one.
Perfect fit!
Storm clouds, then BOOM!
Site supervisor shuts the job down for everyone's safety.
Storm passes and the jib is put on the crane for greater reach.
Two sections up and two to go.
3rd section guided into place.
Top section's 6 foot lightning rod, which we really don't need today.
Top section rigged and inspected.
The sun marks the spot.
Waiting for the last piece to fall into place.
Almost there...
New tower is up and a climber in a man basket is sent up to take measurements and snap some pictures.
Measuring tape reads an inch over 170 feet.
Baltimore's newest monopole!
