Which limitation increased labor requirements for Viking-era pontoon bridge construction?

💡 Explanation

The absence of standardized timber lengths meant each timber had to be individually measured and shaped using axes—a type of brute-force measurement. Thus, significantly more hand labor was needed for construction, because timber dimensional consistency minimized fitting steps, rather than other material limited options.
