Not all the towers along a transmission line are identical. Look closely at a tower where the line makes a sharp turn and you will likely find it is wider and beefier than other towers along the route. The added strength and weight are needed to resist the unbalanced pull of the conductors, which might overturn an ordinary tower. These special towers are called deviation or angle towers.
The transmission-line tower everybody knows is an Erector Set latticework of steel girders and diagonal braces. The techniques for designing and building these towers are the same ones used in constructing steel bridge trusses or crane booms. The individual pieces can be made cheaply from rolled steel and then bolted together on the site. This last point is more important than it might seem: transporting a fully assembled tower 100 feet tall is an awkward and expensive business.
This brilliantly engaging book may actually be one of the first to describe and discuss what might be architecture’s true value at this pivotal point in our own history: seeing that everything is connected, and artfully hosting that complexity, before constructively plotting routes towards clarity, pinned up on broad civic, ethical foundations.
So Architects after Architecture, as the title suggests, is not about buildings. Or at least not always, not directly. Buildings are simply one of the ways that this complex yet constructive sensibility might exert itself, but they are certainly not the only way, nor are they always the most potent – as muf’s Liza Fior makes clear here, when she says “the answer to a brief is not necessarily a building.”
