General Building and Industrial Construction

General Structural and Industrial Construction. For solid construction buildings, wide-span hall roofs, steel-glass constructions, and timber frame buildings, we dimension and design stable and durable components and supporting structures. Furthermore, we plan repair and reinforcement measures using shotcrete and CFRP strips for existing structures. As state-recognized experts for acoustic, thermal, and moisture protection, we create the building physics certifications for residential and non-residential buildings, as well as structural fire protection.

Services:

• Housing and Social Housing
• Office and administrative building
• Industrial and Commercial Construction
• University and College Construction
• Hospital construction
• Sports facilities and sports buildings
• Water and Wastewater Structures
• Sealing surfaces in accordance with VAwS-R.
• Precast concrete and reinforced concrete components

Earthworks and Foundation Engineering

The basis for an economical geotechnical design is the accurate assessment of both soil mechanical parameters and the interaction between the ground and the structure.

All static verifications for deformation and stability are carried out for temporary and permanent, freestanding and anchored constructions, taking into account the respective construction stages.

Services:

• Earth retention systems
• Shallow and deep foundations
• Retaining and Earth Structures
• Trench and shaft structures
• Ground improvement
• Undercuts
• Anchors

Structural Engineering

The Roxeler Engineering Firm prepares structural integrity reports for general building, industrial, and civil engineering, as well as for earthworks and foundation engineering. Our experience and capabilities ensure professional and on-time planning services in accordance with the recognized rules of engineering.

We use complex finite element models and intelligent calculation methods to develop economical, aesthetic, and durable solutions. The realistic discretization of the structural design, taking into account nonlinear and time-dependent material laws, offers scope for architectural design beyond the usual standards.

CAD design for construction

Shop drawings, reinforcement drawings, working drawings, and construction drawings are the basis for the timely and cost-effective completion of any construction project. During construction, detailed execution plans ensure successful collaboration among all parties involved.

Roxeler Ingenieurgesellschaft mbH has many years of experience and a large staff of technical construction draftsmen for the creation of formwork, reinforcement, construction, and structural plans, along with associated steel and parts lists. Our range of services also includes the creation of digital as-built plans in preparation for renovation, remodeling, and reinforcement measures.

Our designers are exclusively civil engineers who, based on their professional qualifications, are capable of independently interpreting the results of structural calculations and using state-of-the-art CAD systems to graphically implement all building structures in general civil and structural engineering.

Services:

• Systematic order processing
• Early detection of planning errors
• Less rework
• Mass and cost security
• Successful implementation on the construction site
• On-time construction execution

Building Physics

As state-recognized experts for sound, thermal, and moisture protection, we create the building physics proofs for residential and non-residential buildings, as well as structural fire protection.

Energy efficiency, sustainability, and environmental awareness are becoming increasingly important in the energy renovation of existing buildings and in the energy-efficient, environmentally friendly construction of new buildings.

Securing these claims requires targeted and comprehensive building physics planning starting from the design phase. This is carried out in cooperation with all specialist planners involved in the project, as well as taking into account the individual needs of the client.

Services:

• Thermal building physics
• Soundproofing
• Moisture protection
• Energy consulting
• Structural fire protection
• Building physics measurements
• Room acoustics

SiGeKo services

Health and safety coordination
Due to the EC Directive 92/57 (EC Construction Sites Directive), the Ordinance on Safety and Health Protection at Construction Sites (BaustellV) has been in effect in Germany since July 1, 1998. The Construction Sites Ordinance imposes additional duties on the client for the planning and execution of their construction project, which they can delegate to third parties.

Potential hazards:

• Site security, excavation pit, trench.
• Disposal, supply, social facilities
• High-level workplaces, scaffolding
• Electrical hazards, fire, and explosion risks
• Hazardous materials and contamination
• Use of machines and equipment
• Stairwells, floor openings
• Construction site entrances and exits

Goals

• Reducing the risk for all involved
  at construction
• Reduction of third-party risk
• Cost reduction through shared
  Safety devices
• Avoidance of disruptions in the construction process
• Improving work quality

Building conservation

Construction condition analysis and repair planning
Buildings age too. And this leaves marks. Marks that are visible and marks that remain hidden at first glance.

The Roxeler Engineering Company has set itself the task of securing and preserving existing assets and adapting them to changed usage requirements.

Services:

• Damage assessment and expert reports for old buildings
  and new constructions
• Building condition analysis (damage recording and assessment)
  of the current state
• Assessment of Stability and Remaining Service Life
• Development of maintenance concepts according to TR Maintenance
  from concrete structures, ZTV-ING and ZTV-W
• Certified, knowledgeable planners for the maintenance of
  Concrete components
• Object monitoring, site supervision
• Quality assurance of the repair measure

Structural inspection

The obligation of the owner of a structural obligation (Baulastträger) for the safe maintenance of buildings and structures arises from the duty of care for traffic safety according to §§ 823, 836 to 838 of the German Civil Code (BGB) and the requirements of the state building codes. Within the scope of preventive structural inspections, we offer:

Services:

• Certified structural inspectors according to VFIB, BAST
