- Construction cost estimates progress through levels of accuracy as design detail increases: conceptual/order of magnitude (-50%/+100%), schematic/budget (-30%/+50%), design development (-15%/+20%), and definitive/detailed (-5%/+10%). Understanding these levels is crucial for construction managers because decisions and commitments should match the available level of estimate accuracy. Presenting preliminary estimates as definitive creates unrealistic expectations.
