New performance models
New potential for users, investors andowners
The classic waterfall model, which represents the SIA’s linear service approach, no longer satisfies the requirements of the construction and real estate industry. Integrated processes, which make optimum use of the technological possibilities offered by digitization, involve all relevant project participants in the process at an early stage and thus replace the linear sequential phase approach with dedicated, partnership-based cooperation models. Close cooperation with subcontractors in workgroups demonstrably leads to better concepts, stimulates fresh potential and ensures that objectives are achieved right from the start. As global service contractors, we assume responsibility for achieving and securing the goals for the product, quality standards, costs and deadlines defined from the outset. Combined with the digital possibilities, this model permits maximum transparency and creates an ideal platform on which to make the best possible decisions at the earliest possible stage and thus achieve optimum results.
Conventional total services (TS)/general contractor (GC) models are classic waterfall models that lead from pure planning solutions directly to execution. As a matter of conviction, we have not offered the GC model in particular for some years now. In this model, the distribution of tasks, competencies and responsibilities is so imbalanced that conflicts of interest are inherent in the system, and most of the participants end up working against each other rather than together.
