Infrastructure projects are highly complex construction schemes. They require cross-departmental services involving many trades such as tunnel, and road construction, specialist civil engineering, bridge construction or traffic technology. Only when customers, planners, authorities, citizens and sub-contractors work together harmoniously and only if technological, planning, logistic, organisational, managerial, time and resource management tasks are optimised and perfectly attuned can the project become a success. Thanks to extensive technical competences, PORR has constructed a long list of successful projects that are all distinguished by economic efficiency, efficient use of resources, planning and execution optimisation as well as maximal use for the stakeholders.
