Independent limited assurance report

Introduction

IBIS ESG Assurance (Pty) Limited (IBIS) has been engaged by the Directors of Murray & Roberts Limited (Murray & Roberts) to perform an independent assurance engagement in respect of selected sustainability information included in its Sustainability Report (the report) for the year ended 30 June 2019 (1 July 2018 – 30 June 2019). This assurance report is produced in accordance with the terms of our engagement letter signed 19 June 2019.

IBIS is an independent and licensed provider of sustainability assurance services. This engagement was conducted by a multidisciplinary team of assurance specialists with extensive experience in sustainability reporting. The assurance team was led by Petrus Gildenhuys who has more than 20 years’ experience in sustainability performance measurement involving both advisory and assurance work.

Scope and subject matter

The scope of the subject matter for limited assurance in accordance with the ISAE3000 (Revised) assurance standard, as captured in the agreement with Murray & Roberts covering the Group with no exclusions, included:

Environment

  • Scope 1 and Scope 2 (location-based) Greenhouse Gas (GHG) emissions as defined by The GHG Protocol: A Corporate and Accounting Standard – Revised Edition (WRI & WBCSD, 2004) (“GHG Protocol”) from:
    • Diesel used (mobile)
    • Diesel used (stationary)
    • Petrol used
    • Electricity purchased
  • Total amount of energy used
  • Total water withdrawal

Safety

  • Number of fatalities
  • Lost Time Injury Frequency Rate (LTIFR)

IBIS' responsibilities do not extend to any other disclosures or assertions.

Respective responsibilities

Directors of Murray & Roberts

The Directors of Murray & Roberts are responsible for the generation, collection and presentation of the selected sustainability information within the Report.

Murray & Roberts is also responsible for maintaining adequate records and internal controls that support the reporting process during the reporting period.

   

Independent Assurance Provider

IBIS’ responsibilities were to conduct an assurance engagement and to report its conclusions to the Directors in accordance with the assurance procedures followed.

IBIS conducted the engagement in alignment with the International Standard on Assurance Engagements (ISAE) 3000 (Revised), Assurance engagements other than audits or reviews of historical financial information issued by the International Auditing and Assurance Standards Board, which Standard inter alia requires that the assurance practitioner follows due process and comply with ethical requirements.

 

Summary of work performed

Murray & Roberts provided IBIS with the relevant supporting information and documentation related to the selected sustainability information reported.

IBIS applied the Murray & Roberts’ corporate Data Reporting Standards, the Global Reporting Initiative (GRI) Standards, as well as the GHG Protocol (for environmental indicators) as audit criteria in respect of the underlying data in the scope of the assurance engagement.

IBIS’ limited assurance procedures consisted of:

TESTING  

Testing, on a sample basis, the measurement, collection, aggregation and reporting processes in place

INTERVIEWS   Interviews with relevant functional managers at Murray & Roberts to understand and test the processes in place for maintaining information in relation with the subject matters in the assurance scope
INSPECTION   Inspection and corroboration of supporting evidence to evaluate the data generation and reporting processes against the assurance criteria
ASSESSING   Assessing the presentation of information in the Sustainability Report relevant to the scope of work for consistency with the assurance observations
REPORTING   Reporting the assurance observations to management as they arose to provide an opportunity for corrective action prior to completion of the assurance process

Inherent limitations

The reliability of the reported sustainability data is subject to inherent uncertainty, given the available methods for determining, calculating or estimating the underlying information. It is important to understand our assurance conclusions in this context.

In addition, the evidence gathering procedures performed in a limited assurance engagement vary in nature from, and are less in extent than for, a reasonable assurance engagement. As a result, the level of assurance obtained in a limited assurance engagement is substantially lower than the assurance that would have been obtained had we performed a reasonable assurance engagement.

Other matters

The maintenance and integrity of the Murray & Roberts website is the responsibility of Murray & Roberts’ management. Our procedures did not involve consideration of these matters and, accordingly we accept no responsibility for any changes to either the information in the report or our independent assurance report that may have occurred since the initial date of presentation on the Murray & Roberts website.

Restriction of liability

Our work has been undertaken to enable us to express the opinion and conclusions on the selected sustainability information to the Directors of Murray & Roberts in accordance with the terms of our engagement, and for no other purpose. We do not accept or assume responsibility to any third parties i.e. other than the Directors and the company, for our work or for this report to the fullest extent permitted by law, save where such third parties have obtained our prior written consent.

Assurance conclusion

We believe that the information provided by Murray & Roberts and the work performed by IBIS are sufficient and appropriate to form a basis for our limited assurance conclusion.

In our opinion, and based on our limited assurance procedures, nothing has come to our attention that causes us to believe that the selected sustainability information set out in the assurance scope above and prepared for the year ended 30 June 2019, is not fairly represented in all material respects.
