feasibility We use feasibility studies to show you the development possibilities and potential of your property.

studies Together with you, we define the functional and economic framework conditions for project planning. By means of a project study, the feasibility of the specifications is checked and optimal solution variants are defined for the preparation of a preliminary project.

The preliminary project is further developed into a project ready for construction, costs and deadlines are determined and the building permit procedure is initiated. On the basis of the building permit, the implementation plans are drawn up.

planning After the building application has been submitted or already during the building permit procedure, the execution planning begins. In superordinate meetings, we plan and coordinate the building services concept for the points of heat generation, heat distribution, ventilation as well as other focal points and interfaces with the specialist planners. At the same time, the working plans required for construction, such as floor plans, sectional plans, elevation plans and detailed plans, are drawn up.

tendering The devising is structured according to construction processes and serves as a basis for the price offers of the companies. The detailed listing of the individual construction components is carried out by us in consultation with the client.

We perform this task on the basis of the construction description and the findings of the execution planning. The goal is to determine an accurate cost estimate for all types of work.

In the tendering procedure, the offers are compared and conditions are checked in order to award the work and draw up the work contracts.

costs The cost estimate is structured according to the construction cost plan eBKP-H and broken down to the construction cost plan (BKP). The calculated costs/prices are based on empirical values of comparable objects, as well as on guideline offers of different contractors. For object-specific work, bills of quantities are drawn up and contractor quotations are obtained.

We attach great importance to the adherence to the costs of the construction project. The first prerequisite for this is the ongoing review of the boundary conditions so that cost management can be enforced. The most important aspects of cost management are:

Cost estimation during the preliminary project. Continuous control of the targets as well as adjustment of the planning in case of non-compliance. Cost estimate (CT) coordinated with the demands of customers and planners. Preparation/supervision of the submission with continuous control on the basis of the KV. Strictly reported proof of changes. Construction accounting with immediate reaction in case of unplanned costs on the construction site. Construction accounting construction management As project and construction managers, we represent the interests of the client. In cooperation with architects, engineers and installation planners, we ensure quality on site and in the associated administration.
