Our engineering and construction teams work together to identify access, constructability, sequencing and interface requirements before work reaches site.
Greenfield Project Construction
WESMAR supports greenfield projects from construction planning through to installation, commissioning and handover.
Our integrated capability enables clients to engage WESMAR across multiple stages of project delivery, including:
Engineering & Design → Procurement Support → Construction → Installation → Commissioning → Handover
Construction activities are coordinated with project schedules, quality requirements, HSE controls and commissioning requirements to provide a controlled path from design to operational asset.
Mechanical Equipment Installation
WESMAR provides specialist mechanical installation for critical industrial equipment and associated systems.
Our experience includes installation and replacement of:
-
Rotating equipment
-
Mills
-
Gearboxes
-
Pumps
-
Fans
-
Drives
-
Conveyors
-
Mechanical handling systems
-
Turbine-related equipment
-
Process equipment
-
Tanks and associated equipment
Where required, installation can be integrated with alignment, bearing works, shaft and coupling works, equipment rectification and commissioning.
This enables WESMAR to provide more than installation alone — we can support the complete mechanical execution requirement.
Shutdown & Turnaround Construction
Shutdowns demand disciplined planning, controlled execution and a strong understanding of critical path activities.
WESMAR provides construction and mechanical execution support for planned shutdowns, turnarounds and major maintenance campaigns.
Our services include:

From Engineering to Execution
A key WESMAR advantage is the ability to connect engineering decisions with practical construction execution.
Our teams consider:
Design
Constructability, access, interfaces and installation requirements.
Planning
Work sequencing, resources, shutdown constraints and project controls.
Construction
Controlled field execution supported by experienced supervisors and specialist trades.
Commissioning
Testing, verification, reinstatement and support through to operational handover.
This integrated approach helps reduce interfaces between engineering and construction and provides clients with a more coordinated delivery model.
Our Construction Approach
WESMAR's construction approach is built around five principles:
Plan
Understand the scope, site conditions, interfaces and critical path before mobilisation.
Prepare
Establish the resources, equipment, materials, work packs and controls required for execution.
Execute
Deliver construction activities safely, efficiently and in accordance with approved project requirements.
Verify
Inspect, test and verify completed works before commissioning and handover.
Handover
Provide the required documentation, records and support for a controlled transition to operations.
Integrated Project Delivery
WESMAR can provide construction as a standalone service or as part of an integrated project delivery model.
Our broader capabilities include:
Engineering & Design
Project Management & Planning
Construction & Installation
Specialist Mechanical & Rotating Equipment
Asset Integrity & Sustaining Works
Commissioning & Decommissioning
This enables WESMAR to support projects from early contractor involvement through to construction, commissioning and asset handover.
