Verification Statement

To the Stakeholders of Royal Boskalis Westminster N.V.


Bureau Veritas was engaged by Royal Boskalis Westminster N.V. (Boskalis) to provide independent verification of selected performance disclosures as presented in its Corporate Social Responsibility Report 2014 (the CSR Report). The objective of the verification is to provide assurance to Boskalis and its stakeholders over the accuracy and reliability of the reported information and data.

Responsibilities of Boskalis and Bureau Veritas

The collation, calculation and reporting of the data is the sole responsibility of Boskalis. The responsibility of Bureau Veritas is to provide independent assurance to stakeholders on the accuracy and reliability of the selected key performance disclosures, and to express our overall opinion as per the scope of engagement defined in this statement.

Scope of work

The scope of our verification engagement covered the performance disclosures made by Boskalis against the following selected indicators: LA1, LA2, LA4, LA7, LA8, LA10, LA11, LA12, LA13, SO1 and HR2 according to the criteria set out in the Global Reporting Initiative (GRI) 3.1 guidelines.

The reporting boundary for the selected key performance disclosures covers Boskalis’s global operations, excluding joint ventures, in line with the latest IFRS11 standard, covering the period 1st January 2014 to 31st December 2014. For indicator LA7 the reporting scope also includes sub-contracted workers that fall under Boskalis’s supervision.


Bureau Veritas undertook the following activities:
  • interviews with relevant personnel with responsibilities for the collection and management of information relating to the selected performance disclosures;
  • assessing the acceptability and consistent application of the reporting criteria;
  • reviewing the systems and processes for collecting and aggregating key performance indicators data as presented in the CSR report;
  • assessing the understanding and application of the reporting criteria and verification, on a test basis, of calculations and reconciliations with supporting documents;
  • performing analytical procedures and detailed checks on selected datasets

The work was undertaken in accordance with Bureau Veritas’ methodology for assurance of sustainability data and reporting which is based on current good practice, informed by the International Standard on Assurance Engagements (ISAE 3000). The work was planned and carried out to provide a limited level of assurance and Bureau Veritas believes it provides an appropriate basis for its conclusions.

Our Conclusion

Based on the scope of our work we conclude that nothing has come to our attention that causes us to believe that:
  • the selected key performance disclosures are materially misstated and
  • the selected key performance disclosures have not been reliably prepared in accordance with the GRI 3.1 guidelines

Further and more detailed reporting is provided to Boskalis in a separate management report.

Limitations and Exclusions

The scope of our work did not include information relating to activities outside the defined reporting period, statements of a descriptive or interpretative nature, or of opinion, belief, aspiration or commitment to undertake future actions.
