Services
At DCCA, we lead expert civil engineering design solutions in partnership with industry specialists, delivering infrastructure and land development projects across Australia. Our designs align with Austroads, Australian Standards (AS/NZS), local council requirements, and state planning policies, ensuring compliance, efficiency, and sustainability.
1
Civil Engineering Design
Comprehensive civil engineering design and documentation using 12d Model, AutoCAD Civil 3D, MicroStation and industry best practices. We deliver efficient, regulation-compliant, and cost-effective solutions for roads, drainage, earthworks, and infrastructure projects in accordance with Austroads, Main Roads, and Australian Standards.
2
Commercial & Industrial Land Development
Expert civil design for large-scale retail, commercial, and industrial sites, covering earthworks, road access, stormwater management, and utility coordination. Our designs adhere to State Planning Policies, local development standards, and environmental regulations to streamline approvals and ensure sustainability.
3
Earthworks & Drainage Optimization
Using 12d Model and AutoCAD Civil 3d, we develop precise bulk earthworks grading and stormwater solutions to minimize site costs, improve constructability, and mitigate environmental impacts. Our drainage designs align with Australian Rainfall & Runoff (ARR 2019), WSUD principles, and local drainage policies to ensure effective water management and compliance with stormwater discharge regulations.
4
Water Sensitive Urban Design (WSUD) & Stormwater Management
Integrating Water Sensitive Urban Design (WSUD) principles to improve stormwater quality, reduce urban runoff impacts, and enhance sustainability. Using MUSIC software, we model and design bio-retention basins, swales, wetlands, and infiltration systems in accordance with State Government WSUD Guidelines, Best Practice Environmental Management Guidelines (BPEMG), and local stormwater planning policies.
5
Road and Pavement Design
Specialist road and pavement designs for urban, rural, and industrial developments, ensuring compliance with AustRoads, Main Roads, and local government specifications. We design intersections, roundabouts, car parks, and heavy-duty pavements, optimizing traffic flow, safety, and durability.
6
Flood Modelling & Risk Assessment
Advanced flood modelling using TUFLOW, HEC-RAS, and 12d Water to assess flood risks and design mitigation strategies. Our assessments align with Australian Rainfall & Runoff (ARR 2019), Department of Water and Environmental Regulation (DWER) guidelines, and local floodplain management policies to ensure compliance and climate resilience.
7
Site Feasibility & Due Diligence
Providing comprehensive site assessments to support land acquisition, planning approvals, and risk management.
8
Value Engineering & Cost Optimization
We refine designs to reduce material usage, optimize grading, and improve construction feasibility, delivering cost-effective solutions without compromising safety or performance. Our approach follows risk-based assessment methodologies and life-cycle cost analysis, ensuring projects remain viable and competitive.
9
Peer Reviews & Compliance Checks
Independent verification of civil designs to de-risk projects, enhance constructability, and ensure regulatory compliance. We assess projects against Austroads, Australian Standards, Main Roads, and local planning policies to mitigate approval risks and optimize designs for long-term performance.
10
D&C and ECI Support
We provide specialist civil engineering input for Design & Construct (D&C) and Early Contractor Involvement (ECI) projects, ensuring design efficiency, buildability, and cost savings. Our support helps contractors meet local authority requirements while streamlining project delivery.
11
Civil Balance of Plant (BoP)
We provide civil design for Balance of Plant (BoP), including substation works, access roads, earthworks, and drainage for renewable energy projects. Our designs ensure cost-effective, compliant, and constructible solutions tailored to Austroads, ARR 2019, and local authority standards.
