A good product is the first step to a good end result. But it doesn’t stop there: perfect execution is also necessary to achieve a high quality project.
Which is why a number of leading public developers have taken the initiative to have their confidence in the conformity of a construction confirmed through execution certification.
To make the difference with product certification clear, a separate quality mark was applied for:
The COPRO.EXE quality mark is a voluntary collective quality mark of which COPRO is the holder, and confirms confidence in an execution (EXEcute). Other certification bodies use the same .EXE suffix for execution certification.
So far there is one execution for which COPRO.EXE applies: the disposal of tar-containing asphalt (previously under the COPROε quality mark).
Certification for the following executions is in full development:
- Execution of road restraint systems;
- Execution of underground infiltration systems;
- Applying waterproof coverings;
- Execution of trenchless techniques;
- Renovation of sewerage systems.
Specific requirements are imposed by the sector to demonstrate the suitability of an executor. These requirements can relate to the personnel, the equipment, the products, the location and the execution itself. All of these requirements are collected in a Technical Prescription or PTV for short.
Execution certification always takes place according to the requirements of the PTV for this execution. It is a public reference document that can be downloaded for free via the search menu on our website.
Because it can happen that there is a PTV for a product and a PTV for applying that product, a choice was made to include all technical prescriptions for executions in the PTV 8xxx series. This way the distinction between production and execution is immediately clear.
The confidence that the certification body has in the executor is confirmed by the issue of a certificate.
Verification of the validity of a certificate can be done on our website.
Overall management of the execution certification is in the hands of the Steering Group, with representatives comprising public developers, contractors, experts and users.
The Steering Group determines and monitors the general principles of execution certification. It determines the general and specific requirements of the execution certification and ensures that all relevant parties are involved in the execution certification.
The practical implementation of specific execution certifications is handled by Advisory Boards. These are composed of representative of the developers, users and implementers of and experts in this specific execution.
This group develops the rules that certificate holders must follow, and lists the requirements that apply in the context of certification. The rules are published in the form of Special Regulations; the requirements are collected in a Technical Prescription (PTV).
The Special Regulations and the Technical Prescription also serve as guidelines for external oversight that will be carried out by the inspection body/bodies. See inspection.
COPRO functions as a certification body in accordance with established procedures, which are based on the ISO/IEC 17065 standard and are accredited by BELAC. COPRO is accredited by BELAC under certificate number 170 PROD.
A client can expect execution realised under an execution certificate to be done in a quality manner agreed by the sector and to meet a series of requirements that are considered relevant by that sector for the quality of the execution.
Thanks to execution certification:
- the client can expect a quality execution;
- the designer and the architect can focus their attention on their core tasks;
- the general contractor has sufficient confidence that it is working with high-quality executors;
- the executor receives the necessary confidence in its services.
How to recognise?
To verify whether or not an executor has a certificate for a specific execution, the website of the certification body must be consulted. This is the only way to check whether a certificate is valid.
