In response to the forecast demand for open space and parkland, City of Gold Coast acquired 240 hectares of low-lying land at the centre of the cities urban footprint between Nerang, Robina, Mudgeeraba and Clear Island Waters to provide current and future city residents and visitors with generous and diverse recreational opportunities in a central location on the Gold Coast.

Burchills Engineering Solutions and AECOM have partnered to prepare the Master Plan for the truly world class iconic open space Greenheart Parklands project for City of Gold Coast. The design team was hand selected to provide best-for project outcomes and bring a balance of broad design thinking underpinned by detailed local knowledge and technical fluency.

Burchills scope of consultancy services includes input to the development of the Master Plan for Gold Coast Central Park, design report recommendations and production of design plans for Civil Engineering, Hydraulic Engineering, Traffic Engineering, Environment and Ecology. The key technical aspects of the Master Plan design include:

• Geotechnical conditions on the subject site was a significant constraint that needed to be explored, with the available soil on site (marine clays) generally unsuitable for structural fill unless the proper soil improvement strategies were employed.
• The proposed Greenheart parklands is situated on the Guragunba Floodplain surrounded by primarily existing residential development. The floodplain is sensitive to hydraulic changes and therefore significant flood impact assessment works were undertaken to ensure that the development did not cause adverse hydraulic conditions external to the subject site.
• Integration with the proposed Green Heart wetlands project was a key requirement of the project, that sees the water sensitive urban design asset integrated within the park complex. Pedestrian routes and viewing platforms were recommended to enhance the amenity of the wetland system.
• Intersection modelling and transport planning considering a road network link between Stadium Drive, being the main access point, and Gilgai Road and investigation of an alternative secondary connection from Robina Parkway.
• Trasport modelling includes assessment of the change in traffic flows associated with the development on operational capacity and road safety at the locations based on design years, growth forecasts, committed development utilising the City of Gold Coast Strategic Transport Multi Modal Model (GCSTM-MM).
• Burchills transport also advice included Vehicular Access Strategy including Car Parking, Active Transport Strategy, Public Transport Strategy, Water Transport Strategy and Event Management.

The Breakwater development is located in Robina on the Gold Coast QLD. The masterplan envisages a lakeside community with over 2000 dwellings that includes the construction of large lakes that are well integrated into the natural landscape and responsive to the extensive constraints.

The project has adopted an innovative approach to designing a new residential community on the Gold Coast, presenting a consolidated and clear vision for the future Breakwater Robina community that capitalises on its position alongside the City of Gold Coast’s Principal Activity Centre of Robina.
The site sits on the largest floodplain in the Gold Coast Local Government Area, influenced by the Nerang River as well as multiple creek systems.

The site has multiple constraints including but not limited to extensive flooding, major earthworks including mass hauls, poor soils (marine clays), groundwater, localised overland flow, protected vegetation, acid sulphate soils, existing services that are at capacity, as well as sensitive neighbouring communities (school, hospital, residences, etc,).

Due to the number of constraints, and due to our extensive experience in dealing with multi-discipline projects, Burchills was appointed Lead Engineer for the project. We have successfully worked through solutions for the management of each constraint with various approval agencies, and multiple stakeholders, to form an overall development strategy that is cognisant to how each issue affects the other.

The management of these issues have also flowed through to construction. Earthworks for the site comprised over 2,000,000m3 of material across 100 hectares. Burchills was able to lead the development design process to overcome the ultimate design challenges, and also solve constructability issues associated with interdependent constraints during design and planning phases.

Burchills Engineering Solutions (Burchills) were engaged by Toowoomba Regional Council (TRC) as the lead consultant for planning and detailed design, including approvals for new $300m, 150-hectare, sports precinct to undertake the detailed design of all stages of the Toowoomba Regional Sports Precinct (TRSP).

The Toowoomba Region Sports Precinct (TRSP) will be located on a site in Charlton next to the Toowoomba Bypass and adjacent to the Toowoomba Connection Road.

The TRSP development, as envisioned by the Toowoomba Regional Council (TRC), encompasses a multi-sports facility situated between Gowrie Junction Road, Toowoomba Connection Road, and the Toowoomba Bypass.

The facility will address the growing demand for sport and recreation facilities and help attract state and national sporting events to our Region. It will provide a mix of high-quality fields and amenities for a variety of outdoor sporting activities and a district-level recreation park.

The project is being progressed in general accordance with the 2020 Toowoomba Region Sports Precinct Master Plan. The project is on track to complete detailed design by the beginning of 2026 and the precinct will be opened in stages over the following decade.

The 2020 Toowoomba Region Sports Precinct Master Plan is expected to cost $215 million.

Burchills Engineering Solutions were engaged by AVID Property Group (Formerly Villaworld) to complete an Ecological Site Assessment and extensive Rehabilitation Management Plan to inform the rehabilitation of a 10ha ecological corridor along the Pimpama River as part of a residential development at 248 Eggersdorf Road, Ormeau. 

The corridor park will form part of a greater regional ecological corridor facilitating movement of fauna between hinterland and coastal habitat. The proposed development also provides protection of wetland habitat for the rare wallum froglet and the extensive revegetation will include planting of at least 5000 koala food trees.

The development proposed the establishment of Marine Industry landuses across five (5) lots with a combined site area of 9.527ha site. The proposed landuses were to integrate with the existing marine industrial operations and consisted of the Hardstand areas for boat storage and maintenance, vehicle and trailer parking areas, boat building/maintenance sheds, associated marine industry facilities i.e. water and sand blasting facilities and pontoon structures attached to the waterfront of lots.

Ecological investigations included detailed marine plant surveys of both seagrass and mangrove communities, as well as management measures to reduce impacts on these marine plants. A Coastal Hazard Assessment was also undertaken assessing the development against the provisions of the State Planning Policy Assessment Benchmarks and State Development Assessment Provisions State Code 8: Coastal Development and Tidal Works.

Burchills were engaged by the City of Gold Coast to provide specialist engineering and environmental consulting services to support a footbridge upgrade in Tallebudgera.

The bridge traverses the Tallebudgera Creek as Scotty Logan Lane, Tallebudgera Valley, and in 2017 the City determined the structure had reached the end of its serviceable life and replacement was required.

Burchills were involved throughout the project from concept planning, through to detailed design. We have undertaken site investigations, environmental assessments, hydraulic study, civil and structural assessment, options analysis, construction costing, with the final deliverable being detailed design of the replacement of Coplick pedestrian bridge and associated shared path connection to an arterial road. Our scope also covered a number of environmental assessments including a detailed ecological assessment and marine plants survey, which were undertaken to identify the impacts of the potential impacts of associated construction works. The assessments identified the presence of number of listed species and marine plant species (Grey Mangrove, River Mangrove, Salt Couch). which would be directly impacted by the project. Burchills staff liaised directly with the Department of Agriculture and Fisheries (DAF) regarding this matter, with Council electing to pay a financial offset for significant residual impacts resulting from the works.

Burchills Engineering Solutions have been engaged to complete the ecological assessments for the Southport Yacht Club, Super Yacht Berth and Parklands.

Southport Yacht Club is developing a superyacht facility adjacent to Jack Gordon Park, Southport. The $7m project includes a major berthing facility for vessels up to 60m in length along with upgrades to the foreshore and existing parklands.

The project is part of the State Governments $60 million investment in The Spit master plan, which supports job-creating projects that will boost tourism opportunities and improve public amenity for the whole community. The new berth will allow the SYC to cater for more, and larger boats, which opens up the Gold Coast to some of the world’s largest and most luxurious yachts. Burchills are completing the engineering planning and design for the project which includes significant revetment walls, mooring facilities and improvements to the foreshore area. To support this, baseline ecological surveys were undertaken to determine the extent of subtidal and intertidal marine plants within and proximate to the works area. Impacts on these marine plants were quantified and discussions with the Department of Agriculture and Fisheries secured the approval for disturbance to marine plants, with alternative approaches to offsets for Significant Residual Impacts accepted by the Department. Management measures were also outlined for construction and operation of the facility to reduce impacts on retained marine plants.

Burchills were engaged by City of Gold Coast to carry out the investigation, planning report and conceptual design of the proposed replacement of Boyds Bridge in Currumbin Valley.

The Boyds Bridge structure located on Currumbin Creek Road in the suburb of Currumbin Valley within the City of Gold Coast has reached the end of its service life and requires replacement.

The completed Planning Report was used to determine the most suitable replacement bridge option to meet the requirements of Council’s brief. Burchills undertook the investigations, conceptual design and options study to produce a Planning Report for the new bridge and associated approach road works. The four options required assessment to establish road geometry, hydraulic assessment, flood immunity, bridge form, sections, environmental impacts and temporary access means during construction. All four concept options were evaluated using a multi criteria analysis (MCA). Our scope of works included ecological surveys and the production of a Detailed Ecological Assessment which was undertaken to identify the potential impacts of associated construction works. The assessment identified that no vegetation units constituting riverine wetlands were situated in the vicinity of the bridge structure with no marine plants present either. Consideration was also given to the passage of fish species up and downstream of the proposed works area. Burchills staff liaised directly with the Department of Agriculture and Fisheries (DAF) regarding this matter to ensure that the design of the bridge did not require a Waterway Barrier Works permit under the Fisheries Act 1994 and that the design of the proposed temporary construction side-track complied with the Code for Self-Assessable Development – Temporary Waterway Barrier Works.

Burchills were engaged by TMR to complete Road Safety (RSA) for 5 locations around the Gold Coast in preparation for the Commonwealth Games.

Due to the incapacity of sporting venues and transport hubs to accommodate Games ground-based workforce as well as bus drivers, TMR and Games LinQ have identified a need for driver mealing and layover at school and community centre locations around the Gold Coast - Nerang Primary School, Arundel Primary School, Helensvale Primary School, Tugun Community Centre and Carrara Community Centre.

Burchills undertook Road Safety Audit at identified 5 locations proposed for the Bus Driver Mealing Stations

The Road Safety involved review of the proposed bus parking area in relation to visibility at each location for buses entering and exiting the parking bays as well as for oncoming vehicles. Swept path analysis were undertaken to identify any constrains for bus movements entering / exiting the site. Recommendations were made relating to the locations and suitability of bus bays as well as appropriate signage necessary to support the new traffic order. A traffic instruction order plans were prepared for each location.

Burchills were engaged to prepare a Travel Demand Management Strategy as part of the Green Heart Gardens project, which will consist of 4,000 residential units and 8,000sqm of commercial use and is forecasted to increase population in the area by 12,000 people based on 3.0 average people per household rate.

It identified key travel demand management measures and incentives that were implemented to reduce car travel and decrease pressure on the local roads in the vicinity of the site such as Boowaggan Road, Gooding Drive and Robina Parkway.

Travel Demand Management Strategy (TDMS) includes both provision of high quality sustainable transport infrastructure and incentives that improve overall transport outcomes, such as reduced traffic impact of the proposed development on the local road network, congestion mitigation and more reliable transport system.

Proposed improvements to active and public transport infrastructure will also deliver substantial social, economic and environmental benefits to the wider Merrimac and Gold Coast area including:

• Reduced congestion on the local road network;
• More efficient use of the existing and proposed transport infrastructure and services;
• Improved connectivity, liveability and amenity;
• Improved road safety including reduced road accidents and injuries;
• Improved air quality due to reduced emissions from cars; and
• Increased physical activity and public health.

Following an extensive literature review, site accessibility study and workshops with local and state government experts in Travel Planning and Travel Demand Management Strategies, a number of measures were identified as the most likely to succeed at Green Heart Gardens development taking into the account site location and site accessibility to local educational, employment and retail areas.

Burchills Engineering Solutions were been appointed by the City of Gold Coast (The City) to prepare a Business Case for the future upgrading of Yawalpah Road, Pimpama.

Yawalpah Road forms the primary connection between the Pacific Motorway (M1) Pimpama Interchange (Exit 49), the emerging residential communities within Pimpama and the future Coomera Connector (Second M1). It crosses the Gold Coast Line of the Queensland Rail network via an overpass.

The original planning identified the Yawalpah Road classification as a future sub-arterial road and suggested that the road duplication from two to four lanes would be sufficient to cater for the anticipated travel demand. However, the previous road corridor study was completed prior to the announcement of upgrades to the Pacific Motorway (M1) Pimpama Interchange (Exit 49) and the proposed Coomera Connector. The Business Case tested the original planning recommendations against other options using forensic traffic modelling and considering the broader network operations. Given the project’s proximity to the existing and planned major state-controlled roads, the forensic traffic modelling analysis includes the Pacific Motorway (M1) Pimpama Interchange (Exit 49) upgrade works and construction of the Coomera Connector. The Business Case provided The City with a recommendation for the optimal configuration of the Yawalpah Road corridor to ensure appropriate Council Capital Investment.

Burchills have undertaken site investigations, hydraulic study, civil and structural assessment, options analysis, construction costing, with the final deliverable being a Planning Report for the replacement of Coplick pedestrian bridge.

The bridge traverses the Tallebudgera Creek as Scotty Logan Lane, Tallebudgera Valley, and in 2017 the City determined that the structure had reached the end of its serviceable life and replacement was required.

Burchills undertook a detailed hydraulic impact assessment of 6 possible design options for the bridge, including possible refurbishment of the existing structure. 1D/2D coupled hydraulic modelling (TUFLOW) was used to test the impacts of the various design options, with 1D HEC-RAS modelling also undertaken to verify the study and gain an initial understanding of the hydraulic behavior of the bridges.

The hydraulic study was then packaged within a planning investigation that included a whole of life cycle costing analysis as well as a cost benefit investigation. The study was used by the City to inform their bridge replacement program, and is envisaged to form part of a Design and Construct tender package in 2019. Our scope also covered bridge engineering services to support a footbridge upgrade option assessment.  Burchills undertook investigations, structural design concepts, options analysis, design costings, and a structural planning report for the replacement of Coplick pedestrian bridge.

Burchills were engaged by Reece Milburn to complete a regional flood study of the Proserpine River catchment. The purpose of the study was to determine a defined 1% AEP flood level for a proposed development near the town of Proserpine. The project consisted of developing detailed hydrological and hydraulic modelling in URBS and TUFLOW.

Burchills were engaged by Toowoomba Regional Council to complete a drainage mitigation, forward planning study for the Kingsthorpe township.

The study was to build upon a collection of Urban Stormwater Master Planning (USMP) projects completed across the TRC LGA since 2015, which established strategic planning goals for stormwater capital works upgrades, hydraulic master planning, and some regional stormwater management and flood mitigation strategies.

The project consisted of detailed 1D/2D hydraulic TUFLOW modelling and 12D design to ensure the flood mitigation measures proposed within the original USMP are constructible, cost effective and practical, yet still uphold the hydraulic intent of the original modelling. The Burchills team has a strong understanding of not only hydraulic modelling, but detailed civil design and construction and is therefore uniquely suited to ensuring that conceptual hydraulic optioneering processes are able to be carried through to the detailed design and construction phase of a capital works delivery program. Following the Forward Planning phase of the Kingsthorpe Urban Stormwater Master Plan project, Burchills were also engaged to complete the detailed design and construction documentation for the various flood mitigation modules in the township of Kingsthorpe. The works included five (5) detailed design packages, detailed estimates and quantities, and detailed hydraulic assessment of the final designs. The Burchills team has a strong understanding of hydraulic modelling, as well as detailed civil design and construction documentation, which makes us uniquely specialized in the delivery of drainage mitigation works, from planning through to construction.

Burchills were recently engaged by City of Gold Coast to support the implementation of the stormwater drainage network capital works program within the Broadbeach catchment. Burchills was responsible for the Forward Planning phase of the program, where design options assessment and cost benefit analysis were completed for a number of problem areas within the catchment.

A number of design solutions were tabled for each problem area and investigated using 1D/2D TUFLOW modelling. The improvement to habitable floor flooding from each design was established to determine cost benefit. Constructability of the proposed infrastructure works was a key parameter to be considered in the proposed upgrade options, as well as rationalisation of the network, removal of infrastructure that traverses private property, and improved overland flow conveyance where possible. The work also required concept design and detail, to ensure that the proposed upgrade options were clear of other service/infrastructure clashes. After completion of the Forward Planning phase, the designs proposed with the highest cost benefit ratio moved into the Detailed Design and Construction phase.

In 2020 Burchills Engineering Solutions were engaged by the City of Gold Coast Council to undertake the conceptual design, modelling and mapping of the stormwater quantity components of the Local Government Infrastructure Plan (LGIP) for four catchments (Gin House Creek, Lower Coomera River, Currumbin Creek & Pimpama River).

The purpose of the project was to gain an understanding of where existing trunk stormwater infrastructure is unable to support future growth, and what additional infrastructure is required to service future development.

The performance of existing detention facilities, potential detention facilities (on-line and off-line) and the required trunk infrastructure sizing (pipes and channels) within the study areas were assessed for the current development scenario (2016) and in five-year increments from 2021 to 2041 as the ultimate development scenario. URBS hydrology models were built and calibrated to real events for the flows used for the hydraulics calculations. XPSWMM was used to complete the hydraulic analysis and to inform the concept design and sizing of future infrastructure.
