Net domestic product is an interesting concept that I haven't considered before.
The Fed appears to track it somehow, despite the difficulty in measuring it, as the article mentions. Here is a graph I configured on the St Louis Fed site that compares GDP to NDP:

In general, it seems to track GDP pretty well, although recently it appears to have gotten closer to GDP, though I don't have any idea why.
The article's comparison of "wear and tear" as a % of countries' GDP is interesting. Since lower income countries (China, India) often have a lower standards for acceptable maintenance level in both the public and private realm than wealthier ones, it kind of makes sense that they spend less of their GDP on wear and tear.
Also, a lot of the expensive modern infrastructure (airports, freeways, etc) in those countries is relatively new, so a big repair bill might just be further down the road (no pun intended).
Britain in this view is an anomaly, being a high income country with low maintenance spend as a % of GDP.
