Certification of buildings

Anomalies are currently a common problem, even in recent residential and service buildings. These anomalies generally result in direct or indirect costs to their users who see the functionality and safety of their spaces undermined, for the promoter whose work quality image is prejudiced and for the builder who generally bears the costs of the necessary repairs covered by the work guarantee.

In fact, after various inspections of recent buildings it has been noted that there are innumerable anomalies due to construction errors or design errors and omissions.

Wall fracture due to different rates of ground settling.

The building certification service arises from this context and proposes to monitor the undertaking from the design stage to the utilisation start-up stage, to reduce future costs associated with errors and defects in new constructions.

In the initial service launching stage, the analysis will focus, in particular, on the structure and roofing. In a subsequent stage, a more comprehensive number of elements must be inspected for certification, including the installations and systems, the finishing, etc.

This service is essentially for real estate promoters who may gain objective advantages associated with promoting an undertaking’s image of quality. Final consumers also benefit since they invest in a construction of proven quality, safeguarding their investment, while the builders have lower final costs associated with errors and defects, as these are corrected already in the design stage or even in the work stage.

  The service consists of various stages
  1. Design stage: Analysis and review of the structural design.

  2. Work stage;

  3. Inspection of the laying of foundations;

  4. Inspection with the reinforced concrete structure completed;

  5. Inspection of the roofing impermeability work;

  6. Inspection after conclusion of the work and respective finishing.
