Civil Engineering

Witt Consulting - trusted civil engineering solutions built to perform.

Civil engineering is fundamental to the infrastructure we rely on every day — from safe roads and rail networks to resilient buildings and effective water management.

Witt Consulting delivers high-quality civil engineering solutions across major road and rail projects, heritage remediation, and complex foundation design. Our experienced team combines practical engineering expertise with advanced technology, including LIDAR-equipped drone surveys, to produce accurate, efficient, and reliable designs.

We provide end-to-end civil design services, optimising cut and fill, pavements, drainage systems, and construction staging to reduce risk and improve project outcomes. Witt Consulting also offers independent assurance, compliance, and verification services to support confident project delivery.

Stormwater Management & Hydrology Analysis

Stormwater management and hydrology analysis involve evaluating how rainfall becomes runoff and moves through a site or watershed. Civil engineers analyse rainfall, land use, soils, and drainage patterns to estimate runoff rates and design drainage systems accordingly.

These analyses support the design of stormwater infrastructure that controls flooding, reduces erosion, improves water quality, and complies with regulatory requirements.

Construction Staging Design

Construction staging design involves planning the sequence and layout of construction activities to maintain safety, access, and functionality throughout a project.

Civil engineers develop staging plans that coordinate temporary grading, drainage, utilities, traffic control, and erosion measures to minimize disruption and ensure compliance with safety and regulatory requirements while construction is underway.

Assurance, Compliance, & Verification Services

Assurance, compliance, and verification services provided by civil engineers ensure that projects are designed and constructed in accordance with applicable codes, standards, permits, and regulatory requirements.

These services include reviewing plans and calculations, verifying construction activities, and confirming that materials and systems meet specified performance and quality requirements, helping reduce risk and ensure project integrity.

Cut & Fill Optimisation

Cut and fill optimisation involves analysing site topography and grading plans to balance earthwork volumes efficiently.

Civil engineers design grading strategies that minimize excess excavation and imported fill, reduce construction costs, and limit environmental impacts while meeting design, drainage, and constructability requirements.

Projects

Sydney Gateway Stages 1 & 3

The Sydney Gateway project connects Sydney Airport and Port Botany to the WestConnex project at St Peters Interchange. Witt Consulting provided a broad range of geotechnical and structural engineering services throughout the duration of this project.

WestConnex Rozelle Interchange

Witt Consulting was an integral partner, providing comprehensive temporary works solutions and geotechnical expertise across both the civil and tunnel construction sites of the Rozelle Interchange.

Central West Orana

CWO REZ is an energy infrastructure project based in regional NSW, commissioned by EnergyCo. The project involves the construction of a new high voltage electricity transmission network, energy hubs and switching stations to connect new renewable energy generation to the grid.

M7-M12 Integration Project

Since 2023, Witt Consulting has been engaged in temporary works related to structural and geotechnical design, investigation, and construction phase services for the M7-M12 project, including: design of temporary retaining structures, geotechnical inspections and construction advice, and structural condition assessments.
