The most competent method for cost forecasts or predictive cost statements is a cost model that quantifies the planned or assumed component qualities in terms of cost at premium consideration. Thus, determined costs can also be understood in detail and represent alternatives or planning changes in a comprehensible and plausible way.
Such cost models are freely configurable and are thus adaptable to different project phases, appropriate to the respective situation.
So far, element-based cost models have been applied in the conceptual stage for the assessment of planning competitions and requirement programs, in the different planning phases for the assessment of planning results and planning progress, as well as in the phases of preparation of tendering and awarding bids to establish a reference cost model as a basis for comparison.
