Road Design


Greenfield has a wealth of experience in the concept and detailed design of sealed and unsealed roads in rural and regional WA. Over the past 20 years we have been involved in various road design projects including new roads, upgrades of existing intersections, road realignments, car parks, pullover bays, passing lanes and roundabouts. We support our design work with in-house drafting capabilities using AutoCAD and 12d Civil Engineering Design Software. We specialise in working with our clients to ensure we meet their needs in a safe and cost effective manner.

Waterways Analysis
& Drainage Design


Greenfield has significant expertise in the field of waterways analysis and its associated effect on road and drainage design and construction. Our services include a full range of waterways analysis from preliminary concept reviews through to detailed 1D and 2D hydraulic models simulating dynamic interactions of river and drainage catchments. We are then able to use this analysis in designing appropriately sized drainage structures including culverts, floodways, levees and table drains to suit the design conditions.

Road & Drainage Condition Assessments


Greenfield is frequently engaged to complete condition assessments of sealed and unsealed roads, car parks, intersections and various drainage structures. Using our in-house expertise, we assess the remaining useful life of assets to provide the asset owner recommendations on the cost, timing and constructability aspects of maintaining and upgrading their assets. This is a critical service to many asset owners in managing their assets with limited budgets.
