The idea behind the Stacks definition, in a similar way to what is done with networks, is to establish ‘typical Stacks’ and avoid repeating information within the project.<\/strong> Thus it is possible to obtain the Fixture units in each of these typical sanitary Stacks, define their diameter and finally, after undertaking the design of the building sewer system, achieve the complete sanitary drainage system design in a building.<\/p>\n Referring to the drawing plans of our example edification, which we will have at the ground floor the typical Stacks shown in the following image:<\/p>\n From what was done in the first part<\/a> of this tutorial series, we have that each \u2018Typical Stack\u2019 has the following characteristics:<\/p>\n Thus, we will have five Sanitary Stacks (typical) in our DESAG\u00dcES (DRAINS) project. Let’s see how to create them now.<\/p>\n Stacks creation, both sanitary and storm, is similar to what was done in the case of sanitary networks. It is only important to note that you must have activated the Stack tab on DESAG\u00dcES\u2019 main window<\/strong> in order to access to the Stack\u00b4s properties dialog<\/strong>:<\/p>\n Here, besides the already known name and label prefix for the nodes\u2019 names fields<\/strong>, you must select the type of Stack: Sanitary or Soil Stack or Pluvial or Rain Leader.<\/strong> In our case, it will be a Soil Stack (Sanitary).<\/p>\n The difference with the Rain Leader type of Stack is that on it you must specify, instead a network, the exposed area to water precipitation, as detailed in this tutorial<\/a>.<\/p>\n<\/div><\/div>\n When clicking the OK button<\/em><\/strong>, you will see that in the Stack\u2019s nodes table is created, by default, one called \u2018Stack\u00b4s base’. This node corresponds to the discharge point of the Stack and, for most cases, will be at the level of the ground floor of the building.<\/p>\n For Stacks, given its characteristics, the import option from a DXF drawing file is not available<\/strong>, so we will create its branches or sections manually. Let’s start.<\/p>\n Each Stack\u2019s node can have associated one or more typical networks<\/strong>, it being possible to specify more than one per type.<\/p>\n Starting with Stack 1,<\/strong> we know that it is only needed to associate the NW-1 network once per level. So we\u2019ll create four nodes to represent the sanitary Yee fitting at each level and where the respective total fixture units will be incorporated.<\/p>\n Let\u00b4s create the first Stack Node, clicking on Add button in Nodes panel:<\/strong><\/p>\n As seen on above image, we have specified 3 m for node\u00b4s elevation<\/strong> (assuming the story height is 3 m) and, from the list of available networks in the project, we have associated the NW-1 to this node<\/strong>. Similarly, we have created the remaining three nodes to obtain the following table of nodes<\/strong>:<\/p>\n We are ready to add the Stack\u2019s branches clicking on the Add button, Stack\u2019s branches panel<\/strong>:<\/p>\n Note that in the case of the Stack\u2019s branches, is imperative to specify its length; that is, there is no possibility of leaving the software to determine it from the coordinates of each node or elevations.<\/p>\n You can also specify, for each branch, additional fittings to those automatically assigned by the software <\/strong>by clicking the button on the top right corner of the dialog.<\/p>\n You can see in the above image that, for the last Stack\u2019s section (Level4-Level3), we have specified 4 m more of pipe length than actually exists between the two nodes (3 m)<\/strong>. Doing this, we are including in the calculation of total quantities of material, the necessary stack\u2019s extension to the roof of the building<\/strong>. For the remaining sections we will use 3 m.<\/p>\n<\/div><\/div>\n Finally, for this Stack, following will be the table of reaches<\/strong>:<\/p>\n Similarly we have created the Stacks: Stk2 and Stk3, while for Stacks Stke and Stke1 (which, remember, are not really Stacks), we have only defined a node and a short section of pipe so as to not affect the total quantities of materials in the project. For example, the figure shows the data (nodes and branches) for Stke<\/strong>:<\/p>\n Thus we have quickly created the five required Stacks to collect sanitary drainage networks in this building.<\/p>\n We can now design under the premise of letting DESAG\u00dcES determine the diameter of all branches in the created Stacks<\/strong> (option \u2018Set diameter\u2019 unchecked for all branches).<\/p>\n The process followed in the automatic design can be summarized in three steps:<\/p>\n Thus, let\u00b4s click on Calculate button, to see Calculation Results dialog<\/strong>:<\/p>\n Verifying that errors, as disconnected nodes or stack\u2019s branches not discharging (direct or indirectly) to the Stack\u2019s base node, are not found.<\/p>\n When checking the results, for example in Stk3<\/strong>, you can verify that the total fixture units in network NW-3 (15 F.U.s) have been accumulated for a total of 60 F.U.s at the base of sanitary stack:<\/p>\n The materials lists<\/strong>, at this time, includes the stacks\u2019 quantities:<\/p>\n Again, at this level and by the way we have outlined the project components, we cannot yet have the total amounts of materials for our sample project<\/strong>. It is necessary, as will be discussed in the third part of these tutorials<\/a>, to fully define the building drain system, and which will be responsible for capturing the Stacks flow (with sanitary networks included, of course) and thus performing the project\u2019s grand total bill of materials.<\/p>\n![\"Waste-stack-location-on-ground-level-plan\"](\"https:\/\/www.hidrasoftware.com\/wp-content\/uploads\/2015\/01\/01_Waste-stack-location-on-ground-level-plan.jpg\" "\\"Waste-stack-location-on-ground-level-plan\\"")
