The environmental simulation construction site links construction execution with environmental planning. It forecasts noise, vibrations, dust, exhaust gases, and impacts on water bodies to minimize risks, support permits, and plan protective measures in a targeted way. Especially in concrete demolition, special demolition, rock excavation, tunnel construction, as well as during building gutting and cutting operations, it enables a well-founded selection of suitable methods and tools such as concrete demolition shears or rock and concrete splitters from Darda GmbH to achieve technically robust yet environmentally friendly processes.
Definition: What is meant by environmental simulation construction site
Environmental simulation on the construction site is the computer-aided and measurement-calibrated prediction of environmental effects arising from construction and deconstruction activities. These include in particular noise emissions and vibrations, dust and particulate concentrations, exhaust and CO₂ emissions as well as influences on soil and water. The simulation integrates construction sequencing, equipment selection, logistical processes, material flows, and weather data to produce immission forecasts for residents, infrastructure, and protected assets. It is used in planning, updated during execution, and validated through monitoring.
Objectives, benefits, and limitations of the environmental simulation construction site
The environmental simulation construction site supports the selection of low-emission methods, the definition of protective measures, and communication with authorities and neighbors. It helps comply with limits, optimize work windows, and avoid conflicts. At the same time, it has limitations: models simplify reality, weather and construction progress change boundary conditions, and input data can be uncertain. Therefore, the combination of simulation, a precautionary package of measures, and ongoing measurements is crucial, particularly for sensitive works in concrete demolition, special demolition, rock excavation, and tunnel construction.
Relevant environmental factors on construction sites
Noise and vibrations
Noise sources are cutting, breaking, and splitting processes as well as hydraulic power units. Vibrations arise from percussive methods and heavy logistics. A vibration forecast takes the subsoil, distance to sensitive receptors, and equipment parameters into account. concrete demolition shears and stone and concrete splitters are considered lower in vibration and noise compared to percussive methods and are therefore often advantageous in dense urban areas and for existing structures.
Dust and air pollutants
Dust (PM10/PM2.5) arises during breaking, separating, size reduction, and through material handling. Exhaust emissions originate from drives, transport, and power packs. The simulation links equipment profiles, cycle times, construction logistics, and wind fields to estimate dust plumes and concentrations. Measures such as wet cutting, localized extraction, and low-dust splitting techniques significantly reduce emissions.
Water, soil and material flow
Inputs to surface and groundwater can occur via cutting water, fines, oils, or sediments. Models consider runoff paths, retention capacity, and temporary infiltration. Settlement basins, filters, sealed work surfaces, and careful handling of hydraulic oils are central building blocks. The material flow (recycled concrete, steel, natural stone) is considered in the simulation for dust and noise forecasting as well as for planning internal routes.
Climate and resource aspects
Carbon footprint and energy demand are derived from operating hours, performance data, and logistics. Splitting and cutting methods can reduce energy use per ton of material, especially when they enable selective deconstruction and source-separated sorting.

- Monitoring concept: measurement points, trigger values, adaptive control, documentation.
Simulation in concrete demolition and special demolition
In urban deconstruction, forecasts of noise emissions and vibrations form the basis for method selection. concrete demolition shears crush components in a controlled manner, often allowing vibration levels to be significantly reduced. stone and concrete splitters separate massive components without impact and are suitable for work close to the structure on sensitive existing assets. The simulation also represents dust generation from breaking and rehandling and evaluates dust suppression via water mist or by adjusting the cycle.
Simulation during building gutting and cutting
Indoors, room acoustics, vibrations in adjacent occupied units, and indoor air quality take center stage. Cutting methods and combination shears, multi-cutters as well as concrete demolition shears are evaluated by their noise spectra and particle releases. The environmental simulation construction site supports the selection of work windows, extraction points, air exchange rates, and flow paths to control fine dust removal from buildings.
Rock excavation and tunnel construction
In rock, vibrations and air pollutants in tunnels and adits are critical. stone splitting cylinders enable quiet separation cuts in the rock. Model calculations couple airflow with equipment emission profiles to size ventilation concepts, dust suppression, and the safe routing of exhaust gases. During heading, forecasts help comply with vibration limits at structures, utilities, and sensitive equipment.
Natural stone extraction
In quarries, the simulation targets dust plumes, noise, and alternatives to blasting. The targeted use of stone splitting cylinders can detach blocks with low vibration and reduce the need for percussive methods. Wind and topography models support the arrangement of haul roads, crushing points, and screens.
Special deployments with elevated environmental requirements
When working on tanks and vessels or in sensitive industrial plants, emissions control, low sparking, and containment of media require particular care. steel shears and tank cutters are evaluated in the simulation with regard to noise, particles, heat input, and potential media release. Protective measures such as extraction, spark arrestors, containment trays, and supervised work zones are pre-dimensioned.
Selecting methods and tools based on the simulation
- With strict vibration requirements: prefer stone and concrete splitters or concrete demolition shears instead of percussive methods.
- With dust restrictions: wet cutting, splitting techniques, closed crushing circuits, limited parallelization of dust-intensive cycles.
- With noise restrictions: low rotational speeds, encapsulating screens, orientation of hydraulic power packs, time-window planning.
- For water and soil protection: closed loops, filtration, containment systems, separated traffic routes.
Deriving and implementing protective measures
- Technical: water mist, extraction, acoustic hoods, vibration isolation, low-emission drives.
- Structural: noise barriers, mobile screens, enclosures, sealed work surfaces.
- Organizational: sequencing, temporal shifting, material logistics, regulated traffic routes, maintenance plans.
- Personal: appropriate PPE, low-dust and low-noise workplaces, instruction.
Monitoring, calibration and documentation
Monitoring networks for noise, vibrations, dust, and air pollutants validate the forecasts. Deviations lead to adjustment of measures or adaptation of the cycle. Continuously updated documentation provides evidence to authorities and neighbors and supports quality assurance.
Legal and organizational aspects
The environmental simulation construction site is aligned with generally accepted rules of technology and the applicable requirements. It does not replace a permit, but it supports early clarification. Statements should always be made cautiously and checked for the specific project. Close coordination between site management, environmental specialists, and occupational safety is recommended.
Key figures and practical assessment metrics
- Noise levels (e.g., time-weighted levels, assessment levels), frequency-dependent assessment.
- Vibrations (e.g., particle velocity, frequency bands) at foundations and sensitive equipment.
- Dust concentrations (e.g., PM10/PM2.5), dust deposition, and visibility.
- Exhaust indicators (e.g., NOx, CO, CO₂ equivalents) and energy use per ton of material.
- Water parameters (e.g., turbidity, pH, conductivity) and retention capacities.
Sustainability and resource conservation
Selective deconstruction facilitates source-separated separation of concrete and reinforcement. concrete demolition shears support targeted release of components, steel shears the separation of profiles, while stone and concrete splitters open massive elements without blasting. The simulation assesses how these approaches influence emissions, energy demand, and transport.
