Seven Basic Requirements for Construction Works

The new CPR has created seven Basic Requirements for Construction Works (BRCW), two of which define relevant product-specific information involving the life-cycle approach.

The greatest environmental impact will come from the new BRCW No. 7 which deals with the sustainable use of natural resources and the expansion of BRCW No. 3 enables it now to cover the reduction of life-cycle impacts of greenhouse gases.

BRCW No. 7: construction works must now be designed, built and demolished in such a way that the use of natural resources is sustained.   The harmonised technical specification for the works  must be take particular notice of:

  •  Recyclability of the construction works, their materials and parts after demolition
  • Durability of the construction works
  • Use of environmentally compatible and secondary materials in the construction works.

Expanded BRCW No. 3: ensures that throughout a construction’s life cycle it must not present a threat to the hygiene, health or safety of workers, occupants or neighbours; or have an exceedingly high impact on the environment quality or on the climate during construction, use and demolition.

Key hazards to guide against include:

  • giving-off of toxic gas
  • emissions of dangerous substances, volatile organic compounds (VOC), greenhouse gases or dangerous particles into indoor or outdoor air
  • emission of dangerous radiation
  • release of dangerous substances into ground water, marine waters, surface waters or soil
  • release of dangerous substances into drinking water or substances which might have a negative impact on drinking water
  • faulty discharge of waste water, emission of flue gases or faulty disposal of solid or liquid waste
  • dampness in parts of the construction works or on surfaces within the construction works.
