Historically, the Sit hut stood for the community-organized workshop network of stonemasons and master builders. In today’s construction practice it likewise describes the central hub of a construction site: the place where planning, pre-assembly, tool maintenance, and knowledge transfer converge. Especially in fields such as concrete demolition, gutting works, rock breakout and tunnel construction or natural stone extraction, this is where the organizational basis is created to work precisely, with low vibration levels, and safely — for example with rock wedge splitter and concrete splitter or concrete demolition shear as well as the associated hydraulic power pack and systems such as hydraulic rock and concrete splitters.
Definition: What is meant by Bauhütte
A Bauhütte is understood as the organizational-methodical unit of a construction project in which specialists, tools, materials, and planning are brought together. Historically, the term referred to the permanent workshop and knowledge community (cathedral Bauhütte) with clear rules, hierarchies, and quality standards. Today, the Bauhütte includes the construction site setup and the workshop environment in which construction logistics, production steps, adjustments, training, and safety procedures are coordinated — from stone processing to the controlled demolition of concrete components.
Historical roots and development of the Bauhütte system
Medieval Bauhütten created cathedrals, bridges, and city walls. Their success was based on knowledge transfer, precise work preparation, and strict quality rules. Stone was shaped with hand tools such as a hand hammer tool and hand chisel; material flow, transport, and assembly followed fixed procedures.
These principles — structured division of labor, documented processes, quality inspection — continue to shape demanding construction and deconstruction projects today. Modern tools such as hydraulic wedge splitter, concrete demolition shear, combination shears (HCS8), Multi Cutters, steel shear, and cutting torch carry on the tradition of controlled material separation — now hydraulically assisted, low in vibration, and reproducible.
Bauhütte today: Organization, logistics, and responsibility
In current projects, the Bauhütte is considered the central place on the construction site: tools are prepared here, hydraulic power pack are tuned, wear parts are inspected, splitting and cutting plans are discussed, and occupational safety measures are defined. This structure increases efficiency in complex tasks — for example in special demolition or rock works — and ensures high execution quality.
Structure of the Bauhütte
- Area for tool reception, cleaning, and maintenance (e.g., changing chisels, jaws, hoses, seals on hydraulic components)
- Material zone for drilling and splitting accessories, rebar cutting accessories, protective devices, pads
- Planning station for drawings, measurement data, sampling, approvals, and documentation
- Safety station with PPE, rescue equipment, hydraulic pressure test device, and barricading material
Material and tool cycle
Tools are prepared and labeled in the Bauhütte and inspected after deployment. Hydraulic power pack are checked for performance, hydraulic hose line routing, and tightness; splitting wedges and cylinders are cleaned, lubricated, and calibrated. In this way, process stability is ensured throughout the entire construction process.
Communication and documentation
Shift handovers, measurement logs, approvals, and records are maintained here. This reduces interface losses — for example when working with a concrete demolition shear in confined areas or for the prepared use of rock wedge splitter and concrete splitter in existing structures.
Tools and methods in the Bauhütte context
The Bauhütte bundles methods of controlled material separation. Selection and combination are based on the component, surroundings, and required accuracy.
- Rock wedge splitter and concrete splitter: hydraulic, low-vibration splitting via borehole patterns — ideal for controlled cross-section reduction, noise control, and protection from vibration.
- Hydraulic wedge splitter: high wedge pressure for precise crack initiation in natural stone and concrete, suitable for rock excavation, foundation demolition, and tunnel excavation without blasting.
- Concrete demolition shear: targeted biting of concrete while exposing the reinforcement; advantageous in gutting works, wall and slab demolition, and selective deconstruction.
- Combination shears and Multi Cutters: flexible separation of concrete and metal — useful with changing materials or component-specific cutting sequences.
- Steel shear: fast, clean cutting of steel sections, beams, and reinforcing steel.
- Cutting torch: controlled cutting of tanks and hollow bodies while observing special protective measures.
- Hydraulic power pack: energy source and pacemaker; pressure and flow rate are matched to the tool, component, and environmental conditions.
Areas of application and typical scenarios
Concrete demolition and special demolition
In sensitive areas — for example near existing structures — low-vibration methods are required. The Bauhütte coordinates borehole patterns, shear sequences, and protective measures against noise control and dust protection. Concrete demolition shear handle the structured removal; rock wedge splitter and concrete splitter reduce cross-sections before components are extracted.
Gutting works and cutting
Before the main demolition, non-load-bearing elements are removed, utilities are separated, and openings are created. In the Bauhütte, cutting sequences are planned, hydraulic power pack are parameterized, and tools such as combination shears and Multi Cutters are prepared. This minimizes downtime and prevents damage to the existing structure.
Rock breakout and tunnel construction
With geologically variable conditions, the Bauhütte enables rapid adaptation of the splitting methodology. Hydraulic wedge splitter and rock wedge splitter/concrete splitter create controlled cracks without blasting and with low vibration — advantageous in urban settings or near sensitive structures.
Natural stone extraction
For the extraction of dimensionally accurate raw blocks, splitting wedges, crack guidance, and protective bedding are prepared. The Bauhütte ensures tool quality, borehole-pattern accuracy, and documentation of separation planes for consistent material quality.
Special operations
For tanks, special profiles, or contaminated sites, cutting and splitting sequences are precisely choreographed. Cutting torch, steel shear, and concrete demolition shear are coordinated; the Bauhütte manages approvals, measurements, and safety measures.
Process planning: From survey to execution
- Existing-conditions survey: load-bearing structure, material, reinforcement, joints, embedded parts, accessibility, utilities.
- Method selection: splitting, shears, cutting — individually or combined; define emission and vibration targets.
- Splitting and cutting plan: borehole patterns, pickup points for the concrete demolition shear, sequences, holding and securing points.
- Energy and hydraulics planning: sizing of the hydraulic power pack, hose routes, pressure ranges, emergency-stop concepts.
- Occupational safety: PPE, barricading, load securing, dust suppression and noise reduction measures, escape route.
- Execution: takt planning, intermediate inspection, adaptation to component behavior.
- Documentation: measurements, photos, test records, construction waste separation, traceability.
Safety, health, and environmental protection
Work in the Bauhütte and on the construction site requires clear protection concepts. These include safe handling of hydraulic pressure, adequately load-bearing supports, sufficient ventilation, low-dust procedures, and noise reduction. Safety distance, barricades, and emergency plans are defined before work begins. Legal requirements may vary by project; a careful, project-specific review of the applicable regulations is recommended.
Quality assurance and sustainability
- Tool condition: wear inspections, calibration of pressure and stroke, documented maintenance intervals.
- Process control: trial steps, measurement points, interim approvals, adjustments in case of deviations.
- Material cycle: construction waste sorting, reuse, short transport routes.
- Protection of the neighborhood: low-vibration splitting sequences, dust suppression, low-noise operation.
Checklists from practice
Before starting
- Component survey focusing on reinforcement, voids, embedded parts
- Method definition: rock wedge splitter and concrete splitter for controlled crack formation, concrete demolition shear for targeted dismantling
- Size the hydraulic power pack, check the hydraulic hose line, perform a leakage test
- Plan barricades, shoring, and load distribution
- Define PPE, rescue equipment, emergency stop, and communication paths
During the work
- Monitor operating pressure and stroke values; check temperature and leaks
- Control splitting progress; adjust borehole pattern if necessary
- Advance shear approach points; document cutting sequences
- Maintain dust protection and noise control; schedule haulage logistics
Avoiding typical mistakes
- Insufficient survey leads to incorrect demolition method selection
- Lack of coordination between tool and hydraulic power pack causes performance losses
- Overly coarse borehole pattern reduces splitting control
- Unclear securing of components increases the risk of uncontrolled movement
- Missed maintenance shortens tool service life of concrete demolition shear and splitting cylinders
Competence development and knowledge transfer
As in the historical Bauhütten, the modern Bauhütte fosters learning on the project: experienced professionals provide guidance, test and measurement data are discussed, and working methods are reflected upon. This culture of continuous improvement improves safety, shortens cycle times, and increases precision — whether in gutting works with concrete demolition shear or in low-vibration removal with rock wedge splitter and concrete splitter.
