Marula Phase 2 EPCM Project.

Design Scope of Work and Footprint

• The scope of work for the EPCM Contractor will include, project management services, engineering design and drawings, and construction management including commissioning of both surface and underground engineering infrastructure and mining development at both declines up to 2030. Note Worley involvement in this project is to December 2025
• Worley will also manage the procurement of the Mining Development Contractor with input from the Integrated Owners Team (IMOT). The EPCM Contractor not will manage the mining contractor, however will be in an advisor capacity on mining schedule and will consult the IMOT team on the Pase 2 development.
• The EPCM Contractor will report to the IMOT while executing the project.  While preparing for the onboarding of the EPCM Contractor, the IMOT is currently carrying out “Immediate Works” planning which includes the design of underground silos and a Dip-6 Conveyor at the Clapham decline as well as the scheduling of raise-boring activities for ventilation shafts.
• The execution of this scope is expected to run for a period of about three years (until 2024). Hence, it is expected that once the EPCM Contractor is onboard (commencing January 2023), the design, integration, construction management, and commissioning of these systems will form part of the EPCM scope of work. Currently, mine development is underway, which will open the mine layout for the above-mentioned installations.
• An independent Quantity Surveyor, (QS) will be appointed by the IMOT to work with the EPCM to fulfil the appropriate QS services and will report directly to the IMOT. Quantity Services will include generating BoQs, drafting contract documents, monitoring costs, assisting with the compilation of TEAR documents, evaluating and approving variation orders, evaluating and approving interim payment certificates, assisting in cost control management, and assisting in the preparation of monthly financial reports.

EPCM Design Scope of Work Deliverable  

• The EPCM contractor will design the infrastructure within the Off-Reef and On- Reef Contractor areas of development to the bottom of the two decline systems. The team will continue with the design of the infrastructure and the installations along strike from the respective level breakaways.

• Raise-boring of two 5.5 metre diameter ventilation shafts.
• Raise-boring of one 4.5 metre diameter ventilation shaft.
• A 40 MVA transformer installation in the Eskom yard adjoining the mine, designed, procured, and installed under the Eskom Self-Build procedure.  
• Surface permanent compressed air line upgrades.
• Permanent compressed air line upgrades in the existing Phase 1 for both declines.
• Installation of permanent compressed air lines in Phase II for both declines
• A 20MW surface refrigeration plant with a 3 x ventilation fan system and bulk air cooler.
• A 10MW surface refrigeration plant with a 2 x ventilation fan system and bulk air cooler.
• Underground dip conveyors (1200mm width) at both declines including fire protection systems.
• Underground strike conveyors (1050mm width) at both declines including fire protection systems.
• Rock passes with chutes feeding onto the various dip conveyors.
• Underground ventilation passes at both declines.
• Underground electrical, C&I, water and pumping systems and reticulation at both declines.
• Chairlifts at both declines.
• Management of a mining contractor who will carry out the development mining activities at both declines including installation of the mining services and blasting of rock passes, silos and ventilation passes.  
• Diesel and lubricant handling systems including installation of piping from the surface through the Phase I decline into Phase II workshops and mining areas at both declines.
