  6. HOLISTIC PROCEDURE. • Demolition • using the gentlest way to demolish a building • using low-noise construction machines which • are up to date with the latest technology • not exceeding the legal maximum limit by • construction noise SEPERATION.

  33. HOLISTIC PROCEDURE. • FUTURE. • Finite resources of relentless domestic construction minerals • responsibility for sustainability in the next generation • reduce the volume of waste and the closure • of material cycles • where it´s reasonable and possible.
