Quality Assurance Act

As of September 30, 2025, builders can distinguish themselves with this new accreditation guideline. Working with this guideline means that the builder and the quality assurer reinforce each other in quality assurance in construction.

ERL 5029: Quality assurance by the builder

SKG-IKOB offers builders the opportunity to qualify for a role in the WKB. This is done via ERL 5029 , developed to demonstrably align with what the WKB requires of you as a builder.
If you are certified under ERL 5029, you ensure that your quality management system and control of the execution process demonstrate what the BBL actually requires of you. In addition, the primary intention is that you, together with the quality assurer involved, can demonstrate that risks have been identified and that you manage them. A quality assurer can therefore "trust" your process control and, as a result, justifiably reduce their efforts in testing your working methods.

More effective and efficient "collaboration" leads to better insight and results regarding the desired quality of construction!

Important for the quality assurance professional within the WKB

A quality assurance company assesses completely independently whether a building plan can comply with and ultimately also complies with the Besluit bouwwerken leefomgeving (Bbl), formerly the Bouwbesluit. The quality assurance officer may not be involved in the realization of the new building project in any other way than in the role of quality assurance officer. A quality assurance officer may therefore not be the client, architect, contractor, etc. of the construction work for which the quality assurance officer is hired.

The certification process starts as soon as the applicant commissions SKG-IKOB Certificatie for certification. Once you have signed and returned our proposal to us, we will contact you to further initiate the certification. The proposal is automatically converted into the certification agreement after a positive completion of the entrance examination.

The certification process consists of an examination (audit) with regard to the quality system of the applicant, in the field of the brl 5019 "Quality Assurance for Building" process.
