Engineering and Design
At Primero our goal remains consistent – to balance quantity optimisation with fit for purpose design to ensure a project performs as prescribed while optimising capital efficiency.
Primero provide professional mechanical engineering solutions spanning equipment selection, mechanical design and drafting as well undertaking upgrade and optimisation studies to existing brownfields infrastructure.
Our team have completed full plant and infrastructure design projects encompassing rotating equipment, bulk material handling and fluid storage and reticulation systems. Plant layouts include piping system and process design, pipe stress analysis and surge analysis where required. Layout efficiency is consistently emphasised to optimise material quantity, constructability and operability with the intention of reducing life cycle cost of ownership.
We self-perform all aspect of structural and civil design and are leaders in plant modularisation and design for constructability. Our structural expertise includes, without limitation to, support structures for equipment, access walkways, platforms, conveyors, silos, surge bins and product storage solutions.
Our electrical and instrumentation group have significant experience in power system analysis, design and delivery, ensuring that any solution we provide is safe above all. Our electrical engineers utilise modelling tools such as ETAP that ensure that all equipment is suitably rated for fault levels and load flow before undertaking protection grading studies and earth grid design specific to the plants electrical system. Our electrical team have intimate experience with the impact large motor starting effects have on power systems, such as mills and crushers, and are familiar with methods to reduce this impact such as by VVVF, LRS SER or straight LRS.
Automation and Control
Primero’s control system engineers are proficient with programming all major PLC / SCADA platforms and hardware. With preference is to complete all control system engineering works in house Primero can provide the highest level of integration between disciplines. Should client specifications not permit in house programming, Primero will develop required philosophies and functional descriptions for input to the client specified system.
Technical Due Diligence
Typically undertaken during an acquisition, takeover or sales process, technical due diligence provides detailed insight into the cost, risk and opportunity associated with the project or asset changing hands. Our process group regularly undertake technical due diligence services for acquiring operators, banks and / or lending consortiums and professional service providers alike. Strict confidentially is always maintained and information censored from all bar those immediately delivering the service.
Engineering, Procurement and Construction Management (EPCM)
Primero are a multi-national engineering group with a global reach. When internationally constrained or where geographically sensible, we render value accretive procurement and construction management services that reduce pre-production capex and improve project economics.
By overlaying best-practice and international accredited procurement, sub-contractor management, safety, construction management and project control systems to an in-country supply chain with often reduced labour and material cost we can unlock financial opportunity and mitigate execution risk.
Primero’s integrated management framework ensures that project performance is repeatedly tracked, monitored and recorded effectively. Highlights of which include:
- In-Country Project Execution Planning
- Detailed Engineering
- International Supply and Procurement Management
- Coordination of International Logistics
- Construction Management
- Operational Readiness
- Maintenance and Asset Management Planning
- Training and Technical Consultancy
