PROJECT DESCRIPTION
The Stage 1 section of the Coomera Connector between Coomera
and Nerang has been identified as the priority section for construction. This section aims to alleviate pressure on the M1 Pacific Motorway by offering an alternative route for the communities and commercial centers of Helensvale and Coomera, by facilitating by additional crossings over the Coomera and Nerang rivers.
Following community consultations in 2020, the northern end point for Stage 1, confirmed as Shipper Drive in Coomera, establishes a corridor wide enough to accommodate an eventual 6-lane motorway. Considering transport demand modeling and available funding, some sections may initially feature fewer lanes to meet medium-term requirements.
Spanning approximately 16 kilometers, Stage 1 will be delivered through three construction packages:
-
STAGE 1 NORTH
Shipper Drive, Coomera to Helensvale Road, Helensvale (SD2HR) -
STAGE 1 CENTRAL
Helensvale Road, Helensvale to Smith Street Motorway, Molendinar (CC-HR2SSM) -
STAGE 1 SOUTH
Smith Street Motorway, Molendinar to Nerang-Broadbeach Road, Nerang. Supports significant activity associated with the Air Combat and Air Mobility Operations and maintains one of the largest networks of airside infrastructure in the Defence Estate.
JC CIVIL PROJECTS ROLE
JC Civil Projects was engaged to assist the Fulton Hogan, JF Hull and McIlwain Engineering JV (FHHMJV) structures team during the design phase with optioneering, feasibility, pricing and innovations for best for project outcomes.
​
KEY DELIVERABLES
JC Civil Projects played a crucial role in several pivotal aspects of the project’s claims progression, including:
-
Delivery of thorough cost estimates of all structures for the project including all bridges, RSS walls, in-situ retaining walls, noise walls and in-situ bridge/road barriers
-
Optioneering and feasibility assessment of design options
-
Identification of risks and constructability issues for each proposed design option
-
Collaboration with JV design team members (including Aurecon, HDR, and Civil Geotechnical Consultants – CGC) to develop innovative solutions for optimal project outcomes
-
Coordination with key subcontractors, such as piling, to ensure accurate pricing and risk documentation, mitigating interface issues between subcontracted works and self-performed activities
KEY PROJECT HIGHLIGHTS
The Coomera Connector Stage 1 - Central extends from Helensvale
Road to Smith Street Motorway (CC-HR2SSM). The scope includes
construction of:
-
8km two lanes in each direction between Helensvale Road to Smith Street Motorway (HR2SSM)
-
Service interchanges (GC Highway and Smith Street)
-
Multiple (20+) new bridge structures over road and over rail
-
Modifications to multiple existing bridges over existing roads, light rail and heavy rail
-
De-construction of existing bridge and construction of a new bridge on Ridgevale Drive
-
Realignment of existing roads
-
New carpark opportunities at Helensvale Light Rail Station
-
Future pedestrian accesses in urban centres of the project
-
PUP design and protection / relocation along the alignment
-
All temporary works required for site access, traffic management during the construction works, including design of any environmental control devices in sensitive environment (both natural and urban)
-
Hydraulic design / improvements
-
Complex geotechnical: soft and hard soil design / treatments
-
ITS, CCTV and VMS works
-
As well as associated design and management works: noise attenuation, urban design and landscaping and temporary ancillary facilities during construction including site offices, construction compounds, and stockpile sites.
OUTCOMES AND ACHIEVEMENTS
JC Civil Projects delivered thorough cost estimates for all structures of the project and the project was sucessfully awarded to the FHHMJV in December 2022. The design phase was completed in 2023 and construction is now underway.
