Bluff Bridge Crossing Upgrade

SEOSpecialist — Thu, 21 Aug 2025 00:55:46 +0000

Overview

CJC Management Services developed and delivered the structural design and documentation for the new Bluff Bridge over the Orara River. This project replaces the existing timber road bridge that was built in circa 1905 and is nearing the end of its service life, which was prone to frequent flooding, with a modern Super T-Girder concrete bridge structure elevated approximately eight metres higher to enhance flood resilience and provide safer connectivity for the crossing of the Orara River near Lanitza (approximately 30km south of Grafton).

Scope of Works

Structural design compliant with AS5100-2017

Optimisation of Super T-Girder design

Compliance with SM1600 and HLP loading standards

Delivery of IFC documentation within a compressed 5-month timeline

Outcomes

Bridge deck elevated by approximately 8 metres to improve flood immunity

Enhanced access for freight and emergency services during adverse weather

Reduced maintenance requirements for Clarence Valley Council

Strengthened disaster resilience across the regional transport network

Timely commencement of construction in early 2025

Project Impact

The new Bluff Bridge provides improved access for residents, freight, and emergency services, significantly reducing the community’s isolation during flood events.

This project exemplifies CJC's commitment to delivering resilient infrastructure solutions that keep communities connected and supported.

M6 Extension Stage 1

Jaweria Saeed — Wed, 21 Aug 2024 06:25:00 +0000

Scope

The M6 Extension Stage 1 project will provide a motorway standard link between the New M5 at Arncliffe and the existing M1 Princes Motorway at Loftus. It will connect St George, Sutherland Shire and the Illawarra regions to the Sydney Motorway network.

The 3.8km section provides the critical link to the major gateways of Sydney Airport and Port Botany, reinforcing the national importance of the new motorway.

The project will also provide an Active Transport Corridor (ATC) for pedestrians and cyclists between Bestic Street and Scarborough Park North, through the existing reserved M6 corridor.

The project will maintain and enhance connectivity to local and regional destinations, including Bicentennial Park, C A Redmond Fields and areas of open space around Muddy Creek.

CJC role

CJC was engaged to provide constructability and utilities advice for the tender design before issue to the preferred tender teams. Further advice was provided to cost estimators and construction programmers.

Stockton Bridge Half Joint Rehabilitation

Jaweria Saeed — Fri, 14 Aug 2020 06:25:00 +0000

Scope

Stockton Bridge is located over the north arm of the Hunter River, near Newcastle in NSW. Built in 1971, it is a concrete box girder bridge with an overall length of 1,023m. In 2007, the bearings were replaced in the two half-joints and monitoring of the structure has continued since.

From 2016, a design solution for strengthening the half joints was developed. This resulted in a detailed design solution of steel plates being bonded to the concrete. The expected completion of these work is in 2021.

CJC role

CJC was engaged to review the constructability of this design solution and conduct a Constructability and Health and Safety in Design (HSiD) Workshop. This included assessing the methodology chosen to complete the work which requires access underneath the bridge.

CJC was also engaged to undertake a reference design for the access system of a suspended platform and provide advice to TfNSW on the platform procurement.

Australia Avenue & Homebush Bay Drive Intersection Upgrade

Jaweria Saeed — Mon, 29 Jun 2020 06:24:00 +0000

Scope

Transport for NSW (TfNSW) is proposing to upgrade the intersection of Australia Avenue, Homebush Bay Drive and Underwood Road. This roundabout is one of the four gateway intersections providing access between the arterial road network and the Sydney Olympic Park precinct.

The idea of relocating an existing Homebush Bay Drive pier was proposed to TfNSW. CJC undertook a feasibility assessment of the pier relocation, including the development of mark-up drawings for TfNSW Bridge Branch.

CJC Role

CJC Management was initially engaged by Transport for NSW (TfNSW) to undertake a constructability assessment of four proposed options at the strategic design stage. The four options were two tunnel underpass upgrades, a signalised intersection at-grade upgrade and a diverging diamond at-grade upgrade. The scope of the assessment included preparing staging drawings, developing a construction method statement (CMS), undertaking a utilities impact assessment, presenting the outcomes of the assessment at a constructability options workshop, and preparing a report to record the outcomes of the options assessment.

CJC was then engaged to undertake an options assessment of twelve options, including those four options from the original options assessment. The scope included the development of an options matrix and facilitation of a constructability and health and safety in design (HSiD) workshop.

CJC presented as a Constructability Subject Matter Expert at Value Management Workshops in determining the chosen Diverging Diamond Interchange design out three finalised options.
