We provide detailed and realistic calculations of construction and planning costs at an early stage of the project as a detailed elementised cost estimate.
With a transparent, continuous cost update in the planning process and a structured change management system, we consistently monitor cost development throughout the entire project.
In the case of budget overruns, we identify potential savings while respecting and maintaining architectural quality.
Continuously updated cost control during the construction period based on the award budgets is database-driven.
Our cost calculations are based on many years of experience in this area as well as our databases with cost estimates that are constantly updated from current contracts and invoices.

Cost calculations
Reliable cost control is based on realistic budgeting and reliable cost calculation from the preliminary design planning stage.
In order to achieve the necessary depth and accuracy, our in-depth cost calculations are prepared as early as possible as detailed elementised calculations in the third level of DIN based on a mass determination with element formation.
The basis are BIM models, dwg plans, building specifications, material plans, fire protection concept, building physics concepts, position plans…
The costs can also be reported according to trades and / or building components as required.
Methodology
MS Access database developed in-house
Project-specific customised structure of database and reporting
Element-based cost calculation via construction elements with mass structure
Cost detailing down to the 2nd or 3rd digit of DIN 276
Ongoing updating of prices due to a high number of current submissions / final invoices entered
The costs of all other specialist disciplines (e.g. MEP) are integrated
Parallel queries according to cost groups / award units possible
BIM-based mass import as far as possible
Change management
In order to be able to track any changes in the project and their cost effects from the time of cost calculation, a consistent change and decision management system is necessary.
All changes to the project, client requests, optimisation proposals, etc. are priced and presented to the client for a decision, together with an estimate of the resulting scheduling consequences, construction cost developments and the fees required for implementation.
Methodology
MS Access database developed in-house
Customisation to the respective requirements of the client and the project, both in terms of reporting and the form of data exchange.
Recording of all changes based on the results of the cost calculation in the form of project change reports
Information on impact on costs / deadlines / quality
Release and status lists
Integration of all cost groups / specialist disciplines via data exchange interfaces
Both one- and two-stage change notifications can be integrated
Release status and deadlines can be filtered in list form
Continuously updated total cost overview
Cost control / Claimmanagement
With the awarding of the contract to the contractors, continuous cost control begins with an integrated supplement system as a controlling tool for cost management.
The expected final construction costs are continuously updated with forecasts, providing transparency for the client and the possibility of countermeasures.
Methodology
MS Access database developed in-house with project-specific reporting structure
Flexible data exchange for transfer to the client’s cost control
Continuous updating of cost control as part of project monitoring based on the award budgets
Supplement processing is part of cost controlling
Ongoing, up-to-date forecasting of the expected total construction costs
Reporting as individual presentation of addenda for approval and in list form
