The certification procedure

The objective is to be able to deliver to a report of inspection which specifies that the built construction is technology compliant. A certificate of conformity to the ACCROPODE ™ technique, ACCROPODE ™ II, ECOPODE ™, CORELOC ™ or X-bloc® confirmed by the registered trademark CLAS TECHNOLOGY COMPLIANT recognizable by this stamp:

Step 1 Study the profiles


The profiles tell us the nature of the materials and the theoretical depth to which they must be found. They define the thicknesses of these materials. This is the reference set by the designer.

Study 2 The placement drawings

The installation plan tells us if there is a peculiarity on the laying area, such as a rapid change of depth or the connection between two block sizes, for example.

Etape 3 Les TID

Les TID peuvent évoluer d´une année à l´autre en fonction de l´avancement des connaissances sur la technique et des retours d´expérience. CLAS utilise les TID de votre projet à l´exclusion de tout autre.

Pour les blocs ACCROPODE ACCROPODEII CORELOC et ECOPODE nous utilisons les TID établis par CLI et pour les X-bloc® le TID établi par DMC.

 

Step 3 The TID

TID can evolve from year to year depending on advances in technical knowledge and feedback. CLAS uses the TID of your project to the exclusion of any other.

For the ACCROPODE™, ACCROPODE™II, CORELOC™, and ECOPODE ™ blocks we use the TID established by CLI and for X-bloc® the TID established by DMC.

 

Step 4 The inspections

Being an inspector cannot be improvised. It is a profession in its own right that can be learned. Being a professional diver is not enough, but it is essential. An inspector must be rigorous, critical, have a sense of observation and authority.

 

4-1 Inspection of the horizontal berm and the underlayer

This is not an extreme case and it is not uncommon. The underlay does not conform to design or technology. The installation of the ACCROPODE™, ACCROPODE™II, ECOPOD ™, CORELOC™ or X-bloc® blocks, which must comply with the tolerance rules of the underlayer as defined in their respective TID, is not possible. This marks a stop point. CLAS inspectors produce a video with measures to justify their decisions.

When the underlayer and the horizontal berm are approved the placement of ACCROPODE ™, ACCROPODE ™ II, ECOPODE ™, CORELOC ™ or X-bloc® blocks is allowed.

The ACCROPODE ™, ACCROPODE ™ II, ECOPODE ™, CORELOC ™ or X-bloc® blocks are checked several times a day to limit disassembly.

When the placement is TECHNOLOGY COMPLIANT the ACCROPODEII armour is filmed

 

The contractor must then place the toe mount protection before building the armour out of the water. As long as the underwater armour is not properly wedged by the toe mount, the ACCROPODE™, ACCROPODE™II, ECOPODE™, CORELOC™ or X-bloc® blocks are suspended.

 

The contact between the toe mount and the armour blocks is controlled and filmed.

 

 

When the toe mount is in place, ACCROPODE™, ACCROPODE™II, ECOPODE™, CORELOC™ or X-bloc® can be placed out of the water.

The construction out of the water is the subject of the same attentions as the construction under the water. CLAS inspectors conduct a walking tour that is essential and a drone inspection.

The walking tour is completed by a drone inspection. CLAS has developed a special procedure for the use of the drone, which allows us to collect all the information that the walking tour does not give.

 

X-bloc® inspected by drone

 

When the carapace is technically compliant, the crest can be laid and inspected in the same way. Non-compliance marks a stopping point.

Each step of the construction that marks a stop point in the event of non-compliance gives rise to an inspection report. Once the various construction steps have been approved and the proof of compliance established, the CLAS inspector drafts the Technology Compliance Report.

When all stages of construction are completed, from the foundation of the work to the crest, CLAS hands over to the owner or his representative, the complete final document no later than one week after the end of the construction.


All quality assurance documents prepared by CLAS inspectors are updated in real time on site during construction. CLAS's intervention generates no delay in decision making and no delay in payment for the contractor.

The certification procedure put in place by the CLAS inspectors provides the certainty of having ACCROPODE ™, ACCROPODE ™ II, ECOPODE ™, CORELOC ™ or X-bloc® CLASS A
