A blog by Chris Jenkins, Technical Director SPM Assets:
Some years ago I visited the City of Bath in England. An old city built over the remnants of an older Roman city. A fascinating history to explore. Following the underground tourist path, you come to a display board describing how the Romans built their drains, and beside the board is one of those drains. A bricked pipe about 600mm diameter. Still operating as designed 1500 years ago. Yes, there were signs of wear with all the angular aspects of bricks and mortar smoothed by centuries years of operation. There is no doubt that pipe has many more centuries of operation before it reaches the end of its life. So what can we learn about asset lives?
