Low Pressure Supply – Option #1
Below is another round supply duct practice takeoff for you to get comfortable recognizing how different engineers represent the various fittings that are not defined. There are several options available to you with this takeoff depending on what the engineer allows in the specifications. We will provide several optional answers. Don’t worry about the lengths of ducts, just indicate that there is a section of duct required.
Fill in table below for each of the numbered items shown in this image along with the description of the duct or fitting along with its size. Don’t worry about the lengths of duct at this time, just indicate if it’s a section of duct or the type of fitting.
After completing the sheet metal takeoff check your answers online with the corresponding answer sheet for this practice test.
We didn’t ask you to finish all the individual branches, but in this case there would be short stubs of 10” duct to each linear diffuser. What is missing from this engineered drawing is the volume damper for each linear diffuser but don’t worry about that now, just remember to add one in a real estimate as they are required to balance the air to each linear diffuser.
Low Pressure Supply – Option 2
We added an optional method of estimating the previous image as shown below with our modifications. Fittings #6, #8 and #10 will be eliminated and #16 will be added in their place, including item #17. Can you identify the newly added fittings #16 & 17?
