Testing services involving condition surveys and condition monitoring

We perform condition surveys to assess your buildings and prepare reinforcement, refurbishment and monitoring measures.

A major proportion of construction work today takes place in existing buildings. By appraising the condition of the building beforehand, this reduces the risk of cost increases during construction or thereafter. We map the structural interrelationships of your buildings, assess the load-bearing capacity and fitness for purpose and reveal any damage to structural components.

Range of services

We offer the following services:

Condition survey and appraisal

  • Supporting structure (statically constructive, deformations, damage, joint connections)
  • Building physics (climate conditions, thermal bridges)
  • Hidden constructions (using thermography, x-rays, endoscopy, drilling resistance measurement)
  • Condition of wood (infestation of wood-destroying fungi and wood pests, glue joint quality, wood moisture)

Permanent monitoring (building monitoring)

  • Wood moisture
  • Climate
  • Deformations


  • Reinforcement or refurbishment measures
  • Monitoring concepts
  • Costs
