Due to PORR’s broad range of services, it is capable of covering every essential step in the construction value chain with its own activities. Due to the individuality of the orders, the responsibilities and areas of expertise are regulated differently between PORR and its external partners. As a result, aspects of the value chain can be both upstream and downstream. This makes PORR dependent on its clients and customers and their activities.
The overarching focus is on circular construction and on keeping as many resources as possible in the construction cycle in a sustainable manner.
Upstream activities
Upstream activities can include the extraction and processing of raw materials for manufacturing materials, the production of building materials, and the design and planning of construction projects. Key stakeholders include suppliers, engineering firms, architects and planners. PORR can also extract some raw materials itself (e. g. quarrying) and thereby produce materials itself (mix plants). In some cases, it is also commissioned to design and plan construction projects. In this case, the activities described are also part of PORR’s own business activities.
Own activities
The construction of a new project is often preceded by a tender for its execution. Here, participating construction companies must meet predefined requirements. At PORR, decisions on whether to participate in a tender are made as part of bid management. The bid is made by the project managers, sometimes also with the involvement of the prequalification department. After a successful acquisition, the planning of the construction site and procurement begin. This also includes the procurement of materials as well as the selection and commissioning of subcontractors.
The construction and project execution are usually PORR’s largest contribution to value creation. The duration of this phase varies depending on the type and scope of a project. Building construction projects, such as residential buildings and industrial buildings, usually have shorter construction times, while several years are to be expected in civil engineering. The main stakeholders for this phase are the company’s own staff. The handover to the client marks the completion of a project. The waste generated during construction is either recycled by external waste disposal companies or by PORR itself.
Downstream activities
The structure then enters the utilisation phase. This is outside of PORR’s scope of influence and therefore also outside of the value chain.
At the end of a structure’s useful life, PORR takes on the revitalisation or demolition, the professional recycling and the dumping or disposal of materials – provided this has been contracted.
