Sustaining Capital and Restart Support

Sedgman helps clients define and implement sustaining capital activity in operating environments where timing, access, safety, approvals and production continuity all matter. We connect replacement scheduling, brownfield scope definition, shutdown-aligned installation planning, restart support so site changes can move from need to execution with greater confidence. 

Reliable experienced support for sustaining capital work at operational assets is critical for maintaining production targets. Equipment must be renewed at the right time, scopes need to be clear enough for delivery, and brownfield interfaces must be planned around safe access, shutdown windows, operating constraints and the path back to production. Sedgman supports clients through this practical transition point, helping asset renewal and minor capital works progress with the discipline required in live processing environments.

Our sustaining capital and restart support brings together capital equipment replacement scheduling and implementation, sustaining capital works scopes, tie-ins, shutdown-aligned installations and restart services. The focus is not simply on defining a job, but on shaping work so it can be implemented safely, coordinated with site requirements and aligned to the operating rhythm of the asset.

Many sustaining capital programs are driven not only by asset renewal requirements but also by changing operational conditions, throughput objectives, HSE requirements and evolving ore characteristics. Sedgman supports the development of brownfield improvement projects that enhance materials handling performance, increase availability, address operational constraints and prepare facilities for future operating requirements while maintaining alignment with site safety and production objectives.

We also help clients manage the controls that make brownfield change workable: risk management, HSE compliance, stakeholder engagement and minor capital works approvals. By connecting scope, timing, implementation readiness, restart planning and governance, Sedgman helps operating sites approach asset renewal and sustaining works as controlled interventions that protect safety, reduce avoidable disruption and support a smoother return to stable production. 

Outcomes We Focus On

  • Clear timing and implementation pathways for capital equipment replacement.
  • Well-defined sustaining capital scopes that reflect brownfield constraints and operating priorities.
  • Safe, coordinated tie-ins and shutdown-aligned installations.
  • Restart readiness  for sites returning to production
  • Disciplined management of risk, HSE requirements and site interfaces.
  • Stakeholder alignment and approval confidence for minor capital works. 

What We Deliver

We support the planning and implementation of capital equipment replacement so asset renewal is aligned with operational priorities, access requirements, maintenance windows and site constraints. This helps clients make replacement activity more predictable and better connected to the realities of operating assets. 

We support sustaining capital initiatives that improve safety, operational performance as well as asset condition. We define sustaining capital works scopes that are practical, deliverable and suitable for brownfield environments -covering materials handling upgrades, transfer chute improvements, water infrastructure modifications, availability improvement works, production debottlenecking and equipment replacement programs. Services may include conveyor and transfer system upgrades, sampling facility modifications, laboratory infrastructure improvements, DEM-supported chute redesigns and other sustaining capital works required to support evolving processing and ore handling requirements. Scope development considers interfaces, access, constructability, operational impacts, safety requirements and re-entry into production so work is better prepared before implementation. 

Operating assets frequently need to accommodate changing feed characteristics, increased production requirements and new operating strategies. We support studies, engineering investigations and implementation planning that help clients prepare assets for changing operating conditions while managing operational risk, constructability and restart requirements. Specialist expertise includes materials handling investigations, discrete element modelling (DEM), transfer chute performance assessment, sampling system reviews 

We support tie-ins and installations that need to be coordinated with shutdowns, outages or planned site windows. Our approach helps clients consider sequencing, isolation requirements, brownfield constraints, handover points and the practical steps needed to integrate new or renewed assets into existing operations. 

Sedgman supports clients to return assets to production after periods under care and maintenance. Our teams help clients schedule and implement capital equipment replacement, define capital works scopes, coordinate installation, assess restart readiness, manage maintenance and spares inputs, review procedures and HSE requirements, as well as operational readiness services. The result is a controlled pathway for restarting into stable production.  

We support risk management and HSE compliance inputs so sustaining works are planned and implemented with appropriate controls for live operating environments. We ensure safety, environmental, operational and interface risks are understood and mitigated before work moves into the field. 

We help coordinate stakeholder engagement and minor capital works approvals so the right people understand the scope, timing, operational impact and implementation pathway. Clear alignment helps reduce friction, support governance and improve confidence before site change is executed.
