Construction & Project Management Services Perth & WA
From bulk earthworks and pavement build-up through to GPS/UTS precision final trim — delivered by people who understand roads.
Dunamis delivers road construction and precision final trim grading across Western Australia — supporting Principal clients and Tier 1–3 contractors on haul roads, MRWA public roads, access roads, mine site roads, and subdivision roads. We operate as head contractor on defined road scopes or integrate directly into your project team as a specialist final trim and civil works partner.
Four Trimble GPS/UTS equipped graders. MRWA specification capable. Two-week mobilisation from contract.
Road Construction — Our Full Scope
We deliver road construction from initial clearing through to finished pavement — either as head contractor managing the full scope, or as a specialist subcontractor providing final trim, civil works, and plant to your programme. Our capability covers every stage of the road construction process.
Site Clearing & Preparation
Vegetation clearing, topsoil stripping, and site establishment ahead of earthworks — executed to minimise disruption and maximise readiness for the next phase.
Foundation Preparation
Subgrade preparation and compaction to specification — the critical base that everything above it depends on.
Embankment Construction
Cut-to-fill operations, embankment formation, and bulk material movement — delivered efficiently and to grade across all road types
Drainage & Culverts
Stormwater drainage, culvert installation, and surface water management — designed and constructed to protect pavement longevity and comply with MRWA and site-specific requirements.
Sub-grade, Sub-base & Basecourse Construction
Pavement layer construction to specification — sub-grade, sub-base, basecourse, and upper basecourse placed and compacted to achieve the required density and grade ahead of final trim and sealing.
GPS/UTS Final Trim
Precision final trim grading using Trimble GPS/UTS equipped graders — achieving MRWA standard specification of -5mm/+20mm and high-precision +/-5mm where required. Our signature service.
Asphalt, Chipseal & Bitumen Seal Coordination
We coordinate and oversee asphalt, chipseal, and two-coat bitumen seal installation — managing specialist surfacing crews as part of the broader road construction scope.
Line Marking, Kerbing & Signage
Full road finishing works including kerbing, linemarking, and sign installation — coordinated and overseen by DCG as part of complete road scope delivery.
Every road type. Every environment.
From remote Pilbara haul roads to MRWA public road upgrades and urban subdivision roads — we have the plant, people, and experience to deliver across every road construction environment in WA.
Haul Roads
Heavy-duty haul roads designed and constructed for high-traffic mining operations — gradient, drainage, and durability engineered for the loads they carry. Proven across 152km of Pilbara haul road construction for Onslow Iron.
MRWA Public Roads
Road construction and final trim to Main Roads Western Australia specification — intersection upgrades, passing lanes, and rural road construction delivered to -5mm/+20mm MRWA tolerance. Proven on Hunter Road Upgrade, Wheatbelt WA.
Access & Service Roads
Mine site access roads, service roads, and contractor access tracks — built for safe, reliable movement of people, materials, and machinery across active project sites.
Subdivision Roads
Residential and industrial subdivision road construction — earthworks, pavement build-up, and final trim ahead of sealing and line marking.
Mine Site Internal Roads
Internal processing plant and mine site roads — delivered within live operational environments with zero disruption to site operations. Proven at Kemerton Lithium Processing Plant for Albemarle Corporation.
Airstrip Roads & Hardstand
Access roads, hardstand areas, and apron grading for remote airstrip construction — high-precision GPS/UTS final trim to +/-5mm tolerance where required.
Precision final trim — where the road is won or lost
Final trim is the last earthworks operation before sealing — and it’s the most critical. By the time the grader goes on, the programme is under pressure, the sealing crew is waiting, and there’s no room for rework.
Dunamis operates four Trimble GPS/UTS equipped graders — CAT and John Deere — crewed by operators who have spent careers working final trim in civil and mining production environments. They understand tolerances, production targets, and what a Tier 1 site expects. They get it right the first time.
Standard MRWA Specification
-5mm / +20mm
Consistently achieved across public road and civil infrastructure projects throughout Western Australia.
High-Precision Specification
+/- 5mm
For projects requiring tight tolerance control — airstrips, warehouse floors, laydown areas, and dam walls.
