![]() ![]() Additional parametersĪdditional parameters could be added to create more robust schedules that include labor rates, labor hours, sales tax rates, overhead profit percentages, etc. For example, with properly assigned wall layers and thicknesses users can provide gypsum sheet counts for all interior walls for ordering or supply total estimated cost for an 8” CMU wall per unit. Material Takeoffs allow users to more fine tune review bill of materials. Separately only a “Material Takeoff” schedule can reference the “Material: Cost” parameter. Material cost parameters in material takeoff schedules ![]() An example would be a schedule to calculate cost based on wall linear feet, cost based on floor area, or total cost with multiple door types. ![]() A standard Quantities schedule uses the Cost parameter to calculate average cost or cost per object or more complex calculations based on length, height, surface area, or volume. Revit has a cost parameter built into the materials library found under the Identity tab for a different set of cost analysis.Ĭost parameters are editable inside the family Type Properties and utilized inside schedules. ![]() This is found in every furniture, wall, floor, ramp, railing, duct, pipe, etc., nearly every object family has a cost parameter associated. Inside each object family Revit has a native parameter simply called cost. With most solutions in Revit, it starts with a parameter. How does Revit incorporate cost calculations? Cost parameters in quantity schedules While it cannot replace more focused solutions at the moment, it can provide automated and accurate cost estimations once set up in a Revit project template. While there are plenty of third-party software for cost estimation, Revit, being a BIM software, can provide multi-phase cost analysis at any point in the development lifecycle. Now more than ever architects, engineers, and contractors need to adapt better cost analysis techniques earlier on in the development lifecycle. Construction costs expectedly increased by 14 percent in 2022 while the usual YOY increase has been 2-5 percent. Year over year construction costs have steadily increased but over the past couple of years costs have spiked above the norm. ![]()
