Bay & Openings

Introduction to Bays & Openings
By default the IQS Software will break up the span of the building in Bays (ex: a 60 ft. building will have three 20 ft. bays). The default bay spacing will usually be optimized, please keep end wall bays to a maximum of 20 feet. Creating end wall bays larger than 20 feet can result in improper design. Please contact your salesperson if you require end wall bays over 20 feet wide.

Select a Bay to edit by clicking on the blue label. The Bay will become highlighted with a gray box. To adjust the size of the Bay, use the arrows or key in the requested dimensions. The elevation measurement of a Bay allows for a permanent opening within that bay area.

Note: Bay elevation must be set to “0” for the addition of doors and windows.

To add a Bay, click the green “plus sign” next to the word "Bay" located in the blue bar directly above the Bay measurements.

To add a door or window opening, first select the Bay for which the opening will be applied. The opening information will appear below the selected bay. Here you can select the type of door to be installed; type of opening required and edit the opening dimensions.

Note: IQS typically designs around common headroom constraints per door type.
If you are unsure about your headroom requirements please check with your salesperson or consult the door manufacturer and headroom requirements.

•

Factory locate: choose this option when you are sure of the framed openings location in the building. Selecting this will result in the door frame being designed into the wall chosen. All secondary framing (i.e. wall girts) will be cut to fit the opening. Installing the door frame with this selection will be much easier than a field located door.

•

Field locate: choose this option when you are unsure of the exact door location. This option will require the cutting of secondary framing members. Please note that you must never remove a column to place a door.
!!! -REMOVING A COLUMN MAY RESULT IN A DANGEROUS SITUATION. PLEASE CONSULT THE MANUFACTURER PRIOR TO REMOVING A COLUMN OR VERTICAL FRAMING MEMBER. -!!!

•

Sheeted for future use: use this option when you would like the option of having a factory located framed opening in your building, but are not currently ready for its installation. Girts and sheeting will be provided to completely cover the opening. Note: trim will not normally come with this option.

•

Include sheeting (no girts): Use this option when you require additional sheeting for a door that is to be built by others utilizing the same wall panel material.
Note: Please confirm that the area of the actual opening will be sufficient to cover the door. If the door is oversized there will not be enough material to cover.

You can specify the location of the door by changing the offset location in the offset control. Click the C button to the right to center the opening within its available space in the bay.

You are able to specify the door width by adjusting the dimension in the width tab. Though it is not recommended, IQS will allow columns to be used for door jambs in the event the bay spacing is set properly to allow this. Normally a door can be placed in a bay and take up the entire width of that bay. Adjacent bays will have a minimum of 1 foot offset from the door edge. End wall corner columns will have 2 foot minimum edge clearance. See offset for more details on end wall corner minimum spacing.

You are able to specify the door or window height by adjusting the top dimension. Constraints are place on framed openings to accommodate most door types. Currently IQS requires a 2 foot minimum distance above the door. This distance is calculated to the nearest roof edge on sidewalls and to the underside of roof purlins on end walls. Normally slide doors located on end walls are no higher than the side wall eave height unless there is sufficient space to accommodate a horizontal path wide enough to create clearance to the nearest roof line. Note: please call your sales rep if you are unsure about slide door requirements.

You are able to specify the sill height of a window opening by adjusting the dimension in the sill control.
Note: adjusting the sill height will not adjust the top height.

To place a wide opening in an end wall (only) you must first adjust the end wall bay spacing to accommodate the door opening. Multiple wide openings can exist in each end wall, however we typically suggest a maximum of 3 wide openings per end wall with a collective opening width (per wall) of no more than 180 feet. We will use a single opening for our example of properly placing a wide opening in the end wall of a building. We will use a 70 foot wide building with a 50 foot wide (hangar) opening. There are 3 bays by default, therefore there is no need to remove any bays. If there were more than 3 bays, we would delete all but 3 for this example.

1.	Set the bay widths to (bay 1) 10 feet, 50 feet (bay 2) and 10 feet (bay 3) from left to right.

2.	Highlight bay 2 and mouse click the wide opening button. The wide opening will always fill the selected bay.

3.	Select the wide opening Type and adjust any accompanying requirements to suit your specific needs. All end wall doors (including wide openings) are restricted to default clearances. If your application requires a lesser clearance, you may need to get a special quotation.
