Environmental requirements in the construction industry shape planning, permitting and execution of construction and deconstruction projects. They regulate emissions such as noise, dust and vibrations, protect soil and waters, ensure proper waste management, and promote resource conservation. Especially in concrete demolition and special deconstruction, building gutting and cutting as well as in rock excavation and tunnel construction, effective, low-emission methods are in demand. Tools such as concrete pulverizers or rock and concrete hydraulic splitters support compliance with many requirements because they work selectively, precisely and usually with low vibration.
Definition: What is meant by environmental requirement in construction
“Environmental requirement in construction” means administratively imposed, project-specific conditions for construction and deconstruction projects that minimize impacts on people and the environment. These include specifications for limiting emissions (noise, dust, vibrations, exhaust gases), protecting soil, groundwater and surface waters, species protection, waste avoidance and recycling, construction logistics as well as documentation and control. The requirements vary by location, method and project phase and are usually defined through permits, ancillary provisions and site requirements. Legal details depend on the applicable legal framework and, without guarantee, must always be coordinated on a project-specific basis with the competent authorities.
Core requirements and objectives of environmental requirements in construction
Environmental requirements aim to reduce negative impacts of construction activities while enabling safe, resource-efficient project delivery. The focus is on: reducing emissions, protecting sensitive environmental assets, closing material loops, and transparency through monitoring. In practice, this means careful selection of methods and equipment, e.g., the use of concrete pulverizers or rock and concrete hydraulic splitters, which often operate with low dust and low vibration and can therefore better meet urban requirements.
Emissions on the construction site: noise, dust, vibrations
Noise limitation
Noise is typically controlled by time-of-day schedules, maximum levels and cumulative levels. Quiet working methods are therefore key levers. Pressing and cutting methods—such as with concrete pulverizers, steel shears or Multi Cutters—often generate lower peak sound levels than percussive methods. Sound attenuation on hydraulic power packs, enclosures and barriers, calm construction logistics and coordinated working windows are common measures.
Dust reduction
Dust is generated during breaking, separating and loading. Effective measures include localized water misting, wet cutting and separating methods, short drop heights, adapted material handling and clean haul roads. The choice of tool significantly affects dust generation: concrete pulverizers crush concrete under pressure and without impact, which reduces fines. Indoors and during building gutting, low-dust methods are often a prerequisite to avoid burdening sensitive areas.
Vibrations
Vibrations can cause building damage or interfere with sensitive installations. Hydraulic splitting with rock and concrete hydraulic splitters or rock wedge splitters is generally low vibration and suitable for inner-city projects, proximity to existing structures, tunnel headings in sensitive areas, or listed building fabric. Concrete pulverizers work with static forces and thus limit vibration risks compared with impact or blasting methods.
Protection of soil, water and nature on the construction site
Water protection
Requirements often concern the protection of groundwater and surface waters. Impervious pads for power unit and refueling areas, containment trays, spill kits, separated rainwater routing and controlled groundwater lowering are standard. For hydraulic splitting in rock or concrete, safe handling of pressure media is essential; hydraulic power packs should be leak-tight, clean and operated in proper technical condition.
Soil protection and contaminated sites
Soils must be protected against compaction, mixing and pollutant ingress. Traffic areas and material storage are planned to minimize land use and transport. For contaminated sites, special requirements apply to excavation, separation and disposal. Selective dismantling with concrete pulverizers, combination shears or tank cutters facilitates the separation of pollutant-bearing components and safe packaging.
Species protection and vegetation
Tree and shrub protection, closed seasons and replacement habitats can form part of the requirements. Low-vibration methods—such as rock and concrete hydraulic splitters in rock excavation—reduce disturbance in sensitive zones. Working windows are planned to minimize impacts on habitats.
Waste avoidance, material separation and recycling
Selective deconstruction and building gutting
Selective deconstruction is key to circularity. Tools such as concrete pulverizers, combination shears, Multi Cutters and steel shears enable the targeted separation of concrete, steel, masonry, wood and fit-out. This improves purity, reduces mixing and increases recycling rates. In building gutting, precise cutting and gripping techniques are advantageous to cleanly separate lines, conduits and plant components.
Material flow management and documentation
Requirements often demand waste concepts, weigh tickets and complete documentation. Clean separation at the source saves transport, reduces emissions and facilitates proof of compliance. Concrete pulverizers and steel shears in combined use accelerate the presorting of reinforcing steel and concrete debris directly at the point of generation.
Energy, drives and emissions of equipment
Hydraulic power packs
Hydraulic power packs (Hydraulic Power Units) drive shears and splitters. In sensitive areas, lower noise levels, tight fuel and oil circuits, drip-oil control and—where possible—electric or low-emission drives are advantageous. Maintenance, leak-tightness and demand-based power reduce energy consumption and environmental burdens.
Leakage and spill management
Requirements frequently call for measures against leaks: containment trays, oil-absorbent materials, staff training and regular visual inspections. Planning power unit locations on impervious pads with rainwater retention prevents infiltration into the ground.
Methods and tools in demolition under environmental requirements
Concrete pulverizers in concrete demolition and special deconstruction
Concrete pulverizers separate concrete with high static pressure. The method is generally low dust and low vibration and is suitable for inner-city deconstruction, hospital refurbishments and work next to sensitive infrastructure. The targeted bite reduces overbreak, protects existing structures and facilitates subsequent sorting of concrete and reinforcement.
Rock and concrete hydraulic splitters and rock wedge splitters in rock excavation and tunnel construction
Hydraulic splitting uses controlled splitting forces in boreholes to detach rock or massive concrete bodies. This enables precise demolition without blasting, with minimal vibrations and low dust generation. In tunnels and special operations near sensitive installations, requirements for noise and vibrations can often be reliably met.
Combination shears, Multi Cutters and steel shears for building gutting and cutting
These tools efficiently separate beams, lines, profiles and reinforcement. Selective dismantling supports waste separation and shortens dust-intensive rework. Controlled cutting produces fewer secondary damages to existing structures—a relevant aspect under building protection requirements.
Tank cutters in special operations
In the deconstruction of vessels and pipelines, special safety and environmental requirements are often decisive. Tank cutters allow controlled cuts with reduced sparking and limited heat input, supporting compliance with emission and fire protection requirements. Careful gas-freeing and residual content declaration remain fundamental.
Planning, permitting and evidence
Environmental construction supervision and measurement concepts
Many projects require forecasts for noise, dust and vibrations as well as measurement and monitoring concepts. Measurement points, thresholds, times and response plans are defined. In case of deviations, predefined measures take effect, such as switching to quieter tools or additional dust binding.
Construction logistics, traffic management and communication
A construction logistics plan minimizes trips, regulates delivery times, defines routes and avoids congestion. This reduces emissions and increases acceptance among residents. Factual, early communication about noise-intensive phases and low-dust methods creates transparency and facilitates cooperation with authorities.

Focus areas of application
In concrete demolition and special deconstruction, concrete pulverizers support compliance with strict requirements on noise, dust and vibrations. In building gutting and cutting, combination shears and Multi Cutters enable clean separation of fit-out and technical components. In rock excavation and tunnel construction, rock and concrete hydraulic splitters and rock wedge splitters are an alternative to percussive methods when vibrations must be minimized. In natural stone extraction, splitting methods promote material-friendly extraction with reduced environmental impacts. In special operations—for example with vessels—tank cutters help meet specific emission and safety requirements.
Safety and health protection in connection with environmental requirements
Environmental requirements and occupational safety go hand in hand. Low-dust methods improve air quality, quieter processes reduce noise exposure, and low-vibration methods protect adjacent structures. Training, clear work instructions, intact hydraulic systems and careful selection of tools—from concrete pulverizers to rock and concrete hydraulic splitters—are essential building blocks for compliant and safe workflows.
