    Calculation of construction costs

    With the progress of planning & design, the costs for the project can be quantified with increasing precision - from the cost estimate to the cost quotation.

    Planning & design in accordance with the HOAI fee scale

    We are committed to a concept that combines individual planning/design, price security, fixed time frames and proven execution quality.


    Correct and well conceived documents with detailed bills of quantities as a basis optimise the awarding of contracts, the construction costs and the subsequent risks from variation orders.

    Project lead

    Strict project control ensures that costs and deadlines are met during construction and guarantees the required quality.

    Construction site management

    A consistently accurate documentation and subsequent acceptance protects against defects and guarantees a carefree use of the property.

    Cost control

    Investment costs are essential factors in a project. Construction costs should already be optimised at the planning stage in order to reduce subsequent financial risks.


    We offer professional support and monitoring of the construction performance in the sense of a strict deadline and quality control on site.
