There are certain pieces of HVAC equipment or accessories that will not appear on the HVAC Equipment Schedule, depending on the design engineer’s standard of practice. Field installed items might include economizers, backdraft dampers, curbs, duct mounted smoke detectors and VFD’s. Capacity (#3), weights and dimensions are more useful information, including the number of pieces the equipment comes in shipped from the manufacture or anything that would impact labor, including accessories (#4) that need to be field installed. The purpose of the HVAC Equipment tab on your estimating spreadsheet is to allow a place to record vendor quotes (#8) and provide field installation labor (#5) for the equipment. HVAC Equipment Tab on Estimating Spreadsheet The engineer in order to reduce the space required on the equipment schedule, listed the ceiling fan only once, which makes sense, but requires you to double check the drawings and vendor quotes for accuracy of quantity. The above riser diagram is from a hotel where each bathroom had the same ceiling fan installed. For instance, if the drawings have 30 of the same exhaust fan, the engineer may decide to use the equipment tag EF-1, instead of EF-1 through EF-30.Īs shown below this engineer used the same tag (EF-1) for multiple locations, so don’t assume that there is only one as might be implied by the equipment schedule or the vendors quotation, always confirm by reviewing the drawings and details. Some engineers will use the same equipment tag multiple times instead of changing the numerical value to indicate another piece of equipment that is the same they will use the same equipment tag for multiple pieces of equipment that are the same make and model number. EF1 on Equipment ScheduleĪfter recording all of the equipment listed on the Equipment schedules, you’ll need to review the drawings to verify the quantity. Manufactures model numbers are of no use on the estimating spreadsheet, as they don’t provide any useful information for laboring the equipment. Record only the pertinent information that will help you figure labor hours for setting the equipment. You begin by opening your electronic estimating spreadsheet and entering the HVAC equipment listed on the equipment schedules which can be found on the mechanical drawings.
