The teams are a little less presentations to new digital television towers
In Austin, Tex., construction had to be stopped for several months during the nesting season of gold in Paruline Wang.
At Dallas, a construction accident killed three people, because workers are poorly trained.
And in New York, even the highest skyscrapers is not up to him.
For the few companies in the fields of construction of TV towers, the prospect of a bizarre complications, bureaucratic delays and even fatal mistakes only serve to connect the extraordinary challenge is now ahead of them. Under a federal program for contracts ushers in the digital high-definition TV - a timetable that the construction industry may be impossible to accomplish - Tour owners are at a crash program across the country to build hundreds of new television towers, At altitudes up to 2049 meters, is higher than the highest building in the world.
The problem is, in relation to the USA, only a half-dozen teams have experience and training to achieve these towers that nearly a half-mile in the sky.
Together, all buildings Nation’s tour teams can be packed in no fewer than 20 rounds per year. But every year for the next four or five years, the broadcast industry is used to invite to an interview for 100 or more. Broadcasters and tower owners call it a Sisyphean task. And when they do not reach many new digital channels years later, it is the air.
”I do not see how we can do,’’said JC Kline, president of Kline Towers, one of only three companies in the USA, the television building towers. ”We did not have the capacity to do so.”
Assessments by engineers, politicians, bureaucrats and lobbyists spent more than a decade in a tortured, Government-Run-default program for the new generation of television. Well, given that the default is resolved, and the Federal Communications Commission has lent a second television channel of each of the transition, which must find stations 1600 places for antennas.
Almost all of them had opted to admit even thinking about this problem until now, partly because a new round of $ 1000 costs at least a foot, or $ 2 million for 2000, a foot of the structure .
Digital television will not be required, a tour of any other than traditional broadcasting. Thus, in many cases, the towers may suffice. But as a nation than a third of television channels, new towers, because their loads are already available to strengthen the capacity of television antennas and radio, mobile telephony and other providers of communication systems. For these towers is fully charged, even more than one antenna - with up to 2000 meters above the copper cable leading to the grease - would add more weight than it can bear.
Several stations have different requirements at the height of its towers, depending on the terrain and distance from the city suburbs. More tower, the signal to reach. But is 2049 meters high tower permitted by federal law.
The National Association of Broadcasters and Tom Vaughan, an industry consultant, specializes in high-rise, saying its recent surveys of the nation’s television stations indicate that 500 to 700 of them need new towers. And while some leaders dissemination of the opinion that such figures can be a bit too high, most stations have rented offices engineers to determine whether their existing towers can be reinforced or modified or whether, just completely new structures are needed.
But no matter what the final number of new shows tours, and many other national leaders know volume of work is disheartening.
”It is something that the world has ever seen up there,’’said Bob O. Niles is with the tower construction for the programme ABC owns 10 stations and expects to build new towers for two of them. ”It is a serious problem.”
An ABC stations in Philadelphia, in collaboration with the station CBS to build a tower to the campaign, already reserved for television towers.
But in most cities, the choice is not so simple. In New York, for example, the leaders of the region, 12 television stations know there is no leeway for other antennas on the roofs of the World Trade Center towers. And they must explore several options: the conviction of the port authority to do so, they have a shorter third round alongside those already on the World Trade Center; CBS sharing the help of troops from the tower summit the Empire State Building, to find other tallest buildings in New York can support towers, a building or 2000 feet independent tower somewhere in the vicinity of Manhattan.
But each faces its own ideas enormous technical problems and bureaucratic.
”Nobody is really sure, nor how we will go,’’said the pope Lew, an intra-industry committee, which tries to resolve, New York City’s Tour problem.
Earlier last month, industry verschlafene high tower was a small shop, which was depressed since the early 1980’s, if growth in the television industry slows. In recent years, Kline, with its two friendly rivals - LeBlanc Communications Inc. Stainless Inc. - were invited together for maybe 10 or 15 rounds per year high, as new stations have begun and already have replaced existing towers from time to time.
