Outta There!

Back to the stories from the McCarran Airport project…

The two or three week job I had come to Las Vegas for was turning out to be a much bigger project than anticipated and my boss and I decided that it made sense for me to stay for as long as it took to get the project back on schedule.

And every day was a challenge as we had to fight the bureaucracy from Bechtel in everything we did. Plus, we had the additional challenge of working a major remodel project in a 'live' airport. Nothing could be done that might slow down the operation of the airport. We had to work around and over the passengers that filled the terminals.


The portion of the terminal that I remember best was called the South Terminal. If you have ever been to this airport, it's the terminal that holds Southwest Airlines. We had to construct a new ceiling and soffit system at a height of about 24 feet and from the south windows all of the way to the middle of the terminal. All of this would be done while never inconveniencing a passenger in any way.

We had half a dozen rolling scaffolds built so that the bracing was at a height that would allow for people to walk under them if needed. And we moved them very slowly and carefully; not wanting to drop anything of course.

The days went by and the work progressed as planned. First; the framers would use the scaffolds and build the metal framework for the lath that would be attached. After the lath was on, the plasterers took over the scaffold to apply a 1-coat 'veneer' plaster. This plaster was used because it saved so much time over the normal 3-coat system. With the plasterers out of the way, the painters took to the scaffolds and finished up.

All was going well until we got to the center of the terminal. It's at this point that the ceiling changes and ascends to an existing structure far above. To make this transition, the architect had designed ¼ radius barrel shapes to gain the height needed. These were simply called 'clouds'. An apt name as the support for them was somewhere far above us. Support wires from a previous ceiling still hung from a height of about 70 feet. It was impossible to verify their exact anchorage so we submitted a question to Bechtel; could we use those existing wires? After a few weeks, the answer came back that, yes, we should use them. And we did.

All went well and the framing and lath were soon in place. Then it was time for the plasterers to do their job. I was standing on the pedestrian bridge that takes passengers from ticketing to the East Terminal and separates the North and South terminals. From here, I could watch the plasterers just below me.

Suddenly the plasterers began to yell and scramble towards the end of the scaffold. I heard some very loud 'popping' noises and I watched as the 'cloud' crashed down onto the scaffold. Passengers, who had been under the scaffold were running for cover.

The wires we had depended on had failed. Luckily, the scaffolding held the enormous load of metal, lath and plaster that had descended on it. Even so, we quickly barricaded the terminal, shutting off all access to ticketing. Yikes! That got everyone's attention, if the crash hadn't already done so.

I was still standing on the bridge as I could see everything and I was talking to our Reno office, describing the situation (Our 2-way radios could transmit to Reno via relay stations) and asking for assistance. Probably legal assistance!

Just as I finished my conversation, I looked up to see that a TV camera crew was standing next to me, filming the action. And firemen. Everywhere! What was going on? It had only been a few minutes since the collapse of the clouds; how did the word get out? Well, it seemed that the firemen and the TV news people were already at the airport because of a reported gas leak; a false alarm.

I declined to be interviewed and got the crew together to try and stabilize the tangled mess. We soon had a local engineer (hired by us) directing our efforts and a couple of brave volunteers climbed up into the wreckage and then even higher as they looked for something solid to attach chain hoists from. Within a few hours we had the weight off of the scaffold and felt it was secure enough to allow ticketing to resume. How many people missed their flights? I didn't want to know! Each one was a potential lawsuit.

With our engineers help and a lot of work, the clouds were rebuilt and in place within a week; painted. Now the real fun began as Bechtel tried to pin the whole debacle on us. But our piece of paper with their opinion stating that it was OK to use those existing supports saved the day for us. It was quietly agreed to let the matter drop and charges from both sides soon faded away.

And that was the last bit of drama from that project. I do know that we amassed something like 80+ lineal feet of 3-ring binders filled with Bechtel generated paperwork and close to a ton of revised and revised again blue prints. But once the clouds were in place, I was through and could return to Reno and a more normal existence.

ps…one last memory; whenever we flew to Las Vegas in the winter we experienced some very rough take-offs. The Monday morning plane had sat overnight and since the temperatures were in the zero range, the tires developed a flat spot from being parked so long. And one morning as we rumbled along the runway, just about ready to take off, the vibrations grew to a point where the overhead oxygen masks popped out. Now that will wake you up!
