The economic benefit of manifolded duct can be seen in the following example, taken from an actual Hospital case study.
Scenario 2 - Loose Erector Set
In the above, the Loose Erector Set has 9 times as many pieces to off-load (9 versus 1) and 3 times the amount of field joints/cuts to perform (18 versus 6). The economic impact of these two different configurations is shown in the table below.
