The Case for Considering the Aesthetics of Transmission Structures
I read a very interesting and detailed article on T&D World that focuses on something I’ve honestly never thought about – the aesthetics of transmission structures. According to the article, aesthetics is considered for building and bridge designs, so why not for utility infrastructure?
Importance of the Aesthetics of Transmission Structures
The article argues that it is possible to deliver on the aesthetic goals, while simultaneously meeting the economic and functional goals, of any structure. But, for a variety of reasons, utility transmission structures have not been held to the same visual standards as other types of structures like bridges.
Perhaps it’s time for this to change. Even the American Society of Civil Engineers (ASCE) supports the incorporation of aesthetic elements into engineering design, and some experts believe that aesthetic quality can actually enhance functional quality. The key is to have a vision of what the final product will look like, and begin the design process with this end vision in mind.
Adding credibility to this concept is the fact that an ASCE task force recently published a paper entitled Aesthetic Design of Electric Transmission Structures, an effort that originated during committee discussions on steel transmission pole design. The bottom-line conclusion of the report is that utility structures must be contextually sensitive and visually pleasing without sacrificing functionality or economic benefits.
It’s also important to understand that the aesthetics of transmission structures are dependent on certain variables, including:
- Voltage level – The higher the voltage, the larger the structural and right of way requirements.
- Route alignment and topography – This influences how often the structure will be seen by the general populace.
- Construction and maintenance requirements – This impacts structural requirements around access, working spaces and climbing areas.
- Allowable footprint – Determines the types of structures that would be feasible to build.
- Mechanical properties – Placement of insulators and equipment will determine how feasible certain aesthetic properties are.
There’s little doubt that there is growing interest in the aesthetics of transmission structures. Will this emerging trend have any impact on utility emergency preparedness? Only time will tell.
