architectural cost control is an essential aspect of the entire construction process, from the initiative through completion.

In the initiative phase a budget estimate will have to determine the feasibility of a - preliminary - design or preliminary study. Often, the outcome thereof will be indicative of the decision-making whether to develop a project into the next phase.

Whereas in the initiative phase prices are often calculated in m² or m³, in the final design phase it will already be possible to prepare an elements estimate. Following the completion of the specification and contract drawings, a management estimate can be prepared in order to provide insight into the anticipated tender(s) by contractors. A thorough examination of the tender price of a contractor may reveal any inaccuracy in the cost price of the project and be of use in finding alternatives and/or cutbacks in order to avoid a budget overrun.

Finally, in the construction phase, it is recommendable to check the estimates of additions and omissions before awarding the contract.
