Quality Control

What is quality control on a construction site?

Quality control is a process and document that is intended to assist the construction manager. This process and document will be used to draft the quality control programming study for the project. This is prepared according to the constructor’s work plan, where the number and type of tests and trials to be carried out by the accredited laboratory are quantified by integrating the requirements of the specifications with the project measurements, thus enabling the economic valuation to be obtained.

Why is quality control performed?

The Technical Building Code (CTE) establishes the basic quality requirements that buildings, including their installations, must meet in order to satisfy basic safety and habitability requirements.

These basic requirements must be met not only in the design, but also in the construction, maintenance and upkeep of the buildings and their installations.

Verification of compliance with these basic requirements is determined by a series of controls:

  • For on-site acceptance of products
  • Of execution of the work
  • Of the finished work

When does it take place?

This Quality Control Plan is drawn up as an annex to the project. Its purpose is to comply with the provisions of Annex I of Part I of the CTE, in the section corresponding to the Annexes of the Report. Quality control bread is always made according to the requirements of:

  • The applicable regulations in force
  • The characteristics of the project
  • As stipulated in the Specifications of this project.

This annex is not a substantial element of the project, since all its contents are sufficiently referenced in the corresponding “Specific Technical Specifications” of the project.

What does quality control include?

Controls of:

1- Quality

2- Reception of products on site.

3- Execution of the work.

4- Of the finished work.

How is it done?

1- The Director of the Execution of the Work – Technical Architect compiles the documentation of the control carried out, always verifying that it is in accordance with the provisions of the project, its annexes and its modifications.

2- The Constructor collects from the product suppliers and provides to the Construction Manager and the Director of the Execution of the Work the documentation of the products previously mentioned. As well as their instructions for use and maintenance, and the corresponding warranties where applicable.

3- The quality documentation prepared by the Constructor on each of the work units may serve, if so authorized by the Director of the Execution of the Work, as part of the quality control of the work.

Once the work has been completed, the control monitoring documentation will be deposited by the Director of the Execution of the Work, in the corresponding Professional Association or, where appropriate, in the competent Public Administration, which ensures its protection and undertakes to issue certifications of its content to those who accredit a legitimate interest.

In our case the professional association is the CATEB “Col-legi d’Aparelladors, Arquitectes Técnics i Enginyers de l’Edificació de Barcelona”.
