Geelong Road Safety Barriers

Installation of road safety barriers and supporting infrastructure across Melbourne's road network, with extensive underground service investigations informing safe construction and design modifications.

Scope

Keystone Civil was engaged by the Department of Transport and Planning (DTP) to deliver road safety barrier works across median and shoulder sections as part of the Geelong Road Safety Barrier Project.

A major component of the project involved extensive underground service investigations, including service locating, scanning and Non-Destructive Digging (NDD) to identify and verify existing infrastructure ahead of construction. The high density and location of underground services presented significant constraints, requiring sections of the proposed works to be redesigned or removed from the project scope to avoid conflicts with existing assets.

Following service investigations and design modifications, Keystone undertook excavation, ground preparation and construction of concrete ground beams within road medians and shoulders, followed by guardrail installation in accordance with the approved design.

Working within a live road environment, the team coordinated construction around existing traffic movements, underground infrastructure and strict safety requirements, with a strong emphasis on protecting critical services and preventing service strikes.

Project Delivery

Underground service identification and protection were central to the project's delivery. Keystone adopted a proactive approach to service locating and verification, undertaking detailed investigations ahead of excavation to identify potential conflicts and inform safe construction methodologies.

Where existing services conflicted with the proposed barrier alignments, Keystone worked collaboratively with project stakeholders to support design reviews, scope adjustments and revised construction approaches. This early identification of constraints helped minimise the risk of service strikes, avoid unnecessary excavation and reduce potential damage to existing infrastructure.

Works were carefully staged across median and shoulder areas, supported by controlled work zones and comprehensive traffic management measures. Through thorough service investigations, adaptable construction sequencing and a strong focus on risk management, Keystone delivered the works while prioritising the protection of underground assets and the safety of road users and construction personnel.
