Site management controls projects from work preparation<\/em> through to acceptance. In deconstruction, in concrete demolition and special deconstruction<\/a><\/em>, and in building gutting<\/em>, it is the link between planning, execution, and occupational safety<\/em>. It selects methods, coordinates equipment such as concrete pulverizers<\/strong> or hydraulic rock and concrete splitters<\/a><\/strong>, ensures the gentle handling of the existing structure, and keeps an eye on schedule, cost, quality, and environmental requirements (construction)<\/em>. Especially in sensitive applications-from inner-city special deconstruction to rock excavation<\/em> in tunnel construction<\/em>-site management decides on the appropriate, low-emission, and efficient methodology. It also aligns permits, stakeholder communication, and monitoring concepts so that execution remains compliant, predictable, and verifiable.<\/p>\n

Definition: What is meant by site management?<\/h2>\n

Site management is the operational leadership of the construction site. It includes organizing the construction process, coordinating all trades and subcontractors, and ensuring occupational safety<\/em>, quality, and schedule as well as cost management. In the context of deconstruction, building gutting<\/em>, rock, and tunnel works, site management is particularly responsible for method implementation: selecting suitable hydraulic methods, integrating hydraulic power packs<\/em>, handling tool changes, and interface management with disposal<\/em>, construction logistics<\/em>, and inspection bodies. Site management translates planning requirements into executable steps and documents progress in a legally compliant and traceable way. Deliverables typically include method statements, risk assessments, inspection and test plans, and section-by-section releases that create a clear audit trail.<\/p>\n

Tasks of site management in deconstruction and concrete demolition<\/h2>\n

The tasks span from construction sequence planning to acceptance. In practice, the aim is to selectively separate components, minimize vibrations and noise emissions, steer construction logistics<\/em>, and ensure crew safety. For reinforced concrete members, the coordination between pre-cutting, crushing, and haulage logistics<\/em> defines the takt. This includes controlling equipment such as concrete pulverizers<\/strong>, hydraulic demolition shears<\/em> or Multi Cutters<\/em>, as well as the low-vibration use of hydraulic splitters<\/strong> in sensitive environments. Added to this are progress measurement, shift and access planning, and the consistent verification of environmental constraints to avoid unplanned stoppages.<\/p>\n

Method selection: Determining methods and tools in a targeted manner<\/h2>\n

Site management selects methods based on member type, degree of reinforcement, thickness, accessibility, permissible emissions, and surrounding conditions. It compares hydraulic splitting, cutting, pulverizer processing, and shear cutting – always with regard to occupational safety<\/em>, noise emission, vibrations, and productivity. Where required, hybrid approaches are defined, for example pre-splitting of massive components followed by targeted crushing to optimize separation and transport.<\/p>\n

Hydraulic splitting of concrete and rock<\/h3>\n

Hydraulic splitters<\/strong> operate with controlled splitting forces and cause very low vibrations. They are suitable for work close to load-bearing structures, special deconstruction in existing buildings, tunnel heading<\/em>, and rock removal without explosives (non-explosive rock removal<\/em>). stone splitting cylinders<\/em> are positioned in boreholes, the modular hydraulic power units<\/a><\/em> supply the energy. Advantages include precise crack guidance, low noise, and high safety when working in sensitive zones. Borehole patterns, sequence, and pressure stages are specified to control fracture propagation and protect adjacent members.<\/p>\n

Mechanical crushing and separating<\/h3>\n

Concrete pulverizers<\/strong> break reinforced concrete<\/em>, open members selectively, and enable clean separation of concrete material<\/em> and reinforcing steel<\/em>. Hydraulic demolition shears<\/em> and Multi Cutters<\/em> cover changing materials, while steel shears<\/em> are designed for profiles, beams, and reinforcement. A cutting torch<\/em> is used for deconstruction-oriented opening of tanks and pipelines. Magnetic separation and pre-sorting further improve recycling quality and reduce disposal costs.<\/p>\n
