PROJECTS $2 MILLION TO $5 MILLION NOMINEES

ATHERTON WATER QUALITY IMPROVEMENT PLAN

Tablelands Regional Council

The Atherton Water Quality Improvement Plan (WQIP) was developed in response to acute problems with drinking water quality in the Atherton in early 2018. Areas of Atherton were on continuous boil water notices, which were a major burden on the community and the town economy. The project objectives were to reduce the frequency and duration of boil water notices (BWNs) in the scheme, avoid the risk of extending into all of Atherton Township and deliver in a short a time as possible. The WQIP involved operational changes to the water supply scheme to reduce water quality risks until an infrastructure-based solution could be implemented to provide a sustained long-term solution. The infrastructure-based solution involved a capital investment of $3.4M to change the reliance on high risk surface water supplies to groundwater supplies. This required major changes in the mode of operation of the water supply scheme as the delivery of bulk water into the scheme was from an entirely different location. Integration of numerous infrastructure elements was required to achieve the objectives and these were delivered in several concurrent packages to reduce the project time frame. The project received $3.4M in funding from the Queensland Government’s Works for Queensland program and the project reached a major milestone in March 2020 with sustained cessation of BWNs after 786 continuous days. Notably TRC, a relatively small Council was also carrying the development and delivery of the Ravenshoe WQIP in parallel with and with similar objectives to the Atherton WQIP.

OREALLA CRESCENT BRIDGE REPLACEMENT

Noosa Council

Construction of the new $3.8 million Orealla Crescent Bridge at Sunrise Beach, Noosa, Queensland has delivered the local community a stronger and wider bridge with a 100 year life span. But this is no ordinary bridge. In fact, you could call it a major engineering feat. Regular inspections of the bridge as part of Council’s ongoing infrastructure maintenance program identified it as requiring urgent investment works to maintain its current serviceability and ensure it remained safe and accessible for all vehicle types. The project faced the challenge of delivering during the start of the COVID pandemic, landslip issues on the detour route and budget constraints meaning this project required innovative thinking and meticulous planning in order to deliver the project on time, within budget and with a minimal impact on the community. With funding support from the Australian Government as part of the Bridge Renewal Program, Council successfully delivered the bridge which was officially opened for the community in February 2021. Project benefits included: • improved traffic flow and road conditions for all road users • smooth flow of traffic throughout Noosa communities by making sure the region’s bridges remain safe and accessible to all types of vehicles • continued access for freight and reduce ongoing maintenance costs. • enhanced entrance area of Sunrise Beach and improved greenery at the nearby intersection. Over 12,000 vehicles use this bridge daily, reinforcing its importance as a critical piece of infrastructure for the Noosa community.

GOLD COAST OCEANWAY - PALM BEACH NORTH

City of Gold Coast

The Gold Coast Oceanway is a 36-kilometre network of shared use pathways between the New South Wales border and the Gold Coast Seaway. The Oceanway is very popular and provides shared cycle and walking paths along the city’s iconic coastline. Since the early 2000’s, the City has been progressively building the Oceanway to be a world class facility for residents and visitors. Guided by the Gold Coast Transport Strategy 2031, The Palm Beach Oceanway is part of this investment by the City to extend the network of shared cycle and pedestrian pathways and create a better connected Gold Coast. This project runs along the existing road reserve (the Esplanade) between the Tallebudgera SLSC and Twenty Third Avenue at Palm Beach. When complete this new section will include: • 670 metres of 3.5-metre-wide fibre reinforced concrete, Disability Discrimination Act (DDA) compliant shared pathway • a new viewing deck, picnic shelters, water bubblers, bike racks and beach showers at community nodes at street ends. • path lighting and dune vegetation This project is constructed entirely on the beach foreshore on an existing road reserve seaward of neighbouring private properties. Dune revegetation works are incorporated into the project scope to further increase resistance to coastal erosion and improve dune vegetation ecosystems with formalised beach access ways to protect adjacent dune vegetation at key locations. The project value is $3 million and the construction period is 6 months with completion expected by August 2021.

BOYNE ISLAND WASTEWATER TREATMENT PLANT POND RELINING AND PUMP STATION

Gladstone Regional Council

The Boyne Island Wastewater Treatment Plant (WWTP) is located in a small coastal town in the Gladstone Region. The WWTP is situated approximately 300m from the shore line and is subject to relatively high groundwater levels. There were two ponds at the Boyne Island WWTP; an effluent storage pond and an emergency storage pond. The effluent storage pond was concrete lined and always contained effluent. The emergency storage pond had a grouted rock liner and was only used during bypasses when fixing components of the WWTP or during overflow events. This project was required to line the emergency storage pond to prevent sewage leeching into the groundwater through the cracks in the grouted rock liner. During initial groundwater investigations it was discovered that the groundwater was not only high but also impacted by the tides. As a result there were concerns regarding buoyancy of various liner options. In addition, the existing above ground pump station had to be recommissioned. Unfortunately, this became not possible and the works for a new pump station needed to be brought forward. Following investigations, the pond was relined with a concrete liner with additional base thickness to combat the effects of the groundwater buoyancy and a new pump station was constructed at the same time to save overall project costs by completing both projects simultaneously.

CABOOLTURE TO WAMURAN RAIL TRAIL

Moreton Bay Regional Council

The Caboolture to Wamuran Rail Trail is the latest in a growing number of recreational cycleways within the greater south-east Queensland region. It is a 10.5km long, shared pathway extending from Beerburrum Road, Caboolture to Atwood Street, Wamuran within the Moreton Bay Regional Council area. It is a unique project which follows the disused Caboolture to Kilcoy railway corridor - an historic trading and transport route - which closed in 1964. The aim of the rail trail is to showcase the rich history and landscape character of the area by providing a generous, high-quality 3-3.5m wide pathway and supporting infrastructure attracting cyclists and walkers to the region. The trail traverses a varied landscape from the light industrial outskirts of Caboolture to the wooded and agricultural properties of Wamuran. Wayfinding and interpretive signage along the route provide visitors with stories and information about early settlement and the timber-getting, farming and transport industries which were the lifeblood of surrounding rural settlements. Remnants of the railway infrastructure have been incorporated into the trail as a tangible memory of Queensland’s regional train network. It provides an important link between several schools by connecting them to nearby residential areas. It is well used by the local community as a commuting track and has been embraced by tourists looking to discover new recreation trails. Contemporary colour theming and materiality reflects the area’s layered history and leads visitors on a distinctive, dynamic journey.

CITYLINK CYCLEWAY TRIAL

Brisbane City Council

Active travel in Brisbane continues to grow, and COVID-19 has changed the way we work, live and travel, with active transport being the safest method of travel while maintaining physical separation. Brisbane City Council’s CityLink Cycleway Trial caters for this ongoing growth by installing a separated bikeway through the middle of Brisbane’s CBD to fill the missing link for cyclists journeying into Brisbane’s city centre. This city-shaping project encourages even more Brisbane residents, visitors and commuters to use sustainable modes of transport and help reduce the need for car-based travel. The CityLink Cycleway Trial is a high-complexity project involving installation of 1.8km of separated two-way bikeway in a densely-utilised and heavily trafficked road reserve. The project works involved: • converting a kerbside traffic lane to a separated cycling facility by including raised kerbing, line marking and signage • relocating many of the previous kerbside uses (e.g. disability parking spaces, loading zones, taxi zones) to new locations nearby • upgrading intersections to include two-way cyclist movements on previously one-way roads • creating a bikeway that also meets requirements to allow for use by e-scooters to contribute to the

City’s e-mobility strategy. The effectiveness of the CityLink Cycleway is being evaluated as part of a 12-month trial period to determine the ultimate long-term success of the bikeway. A range of factors will be considered, including community feedback, usage, traffic analysis and safety. Learnings from this project will be used to inform future projects.

BRISBANE CBD BURST MAINS REPLACEMENT

Urban Utilities

Diona is the Urban Utilities Delivery Partner for design and construction for the Water Northern Zone Program. One of the most significant package of work in the first year of the Program was the Mains Renewal in Brisbane CBD. This highly complex package included replacing over 1km of up to 100-year-old mains within four highly congested inner-city streets with significant design, planning, construction and community challenges. Diona developed innovative ways of communicating project objectives and progress to internal and external stakeholder see figure 1. The CBD is the ‘heart of Brisbane’, critical to the economic, cultural and social function of the City. The works delivered affected the key arteries and potentially affected traffic and visitors on the remainder of the body of Brisbane. Over 200 buildings were contacted with 30 water isolations over 6 months. The scale of the planning is illustrated by the need for over 15,000 community notifications. Under the skin of the city, Diona crossed over 600 services, nine major road crossings, bus and cycle routes and challenging ground conditions. Construction in the CBD presents a daily requirement for dynamic and high consequence decision making. We worked through the night knowing that any unplanned extension to a network isolation could cause major impacts to businesses, and unplanned impacts on traffic flow could cause misery to thousands. Through all this pressure and challenge the project team has delivered a result that is on time, on budget and significant positive stakeholder feedback.

TENNIS CENTRE ROOF

Cairns Regional Council

The Cairns International Tennis Centre Roof project provides an aesthetically pleasing roofed structure over the centre court and facilitates opportunities for year round play with protection from both rainfall and the harsh Far North Queensland sun. The covered centre court has enhanced the reputation and attractiveness of the Cairns International Tennis Centre to professional players as well as enhancing spectator experience at the range of tournaments and events held at the facility. It provides a facitity for elite level training camps in the region as well as future international events such as the Davis Cup or Fed Cup tournaments. The Structure is sited over the main Court of the Cairns International Tennis Centre adjacent the clubhouse. Its lighting, positioning and technical conncetivity is suitable for broadcast standard and it is designed to cater for extensive removable grandstand seating that is owned by Council and located at the adjacent FINA Standard Tobruk Pool facility. Cairns Regional Council received a grant of $997,908 ex GST as part of the Regional Jobs and Investment Packages - Local Infrastructure Stream and contributed the remaining funds of $1,690,000 ex GST. It was opened in 2020 by a panel of professional Tennis Athletes including Australian superstar Ash Barty.

WESTERN SHIRES TMR REST AREA UPGRADE PROGRAM

Proterra Group

The Department of Transport and Main Roads were provided with stimulus funding from the Federal Government to complete reconstruction and improvement works to 27 Rest Area sites on the Darling Downs and South Western QLD State Road Network. This was a significant project fund however it came with the requirement that works had to be completed before the end of the Financial year. That was approximately 16 weeks from the date that the projects were tendered out, to the time that works had to be 100% complete. Proterra Group being a well known and respected Project Management business with project offices in Goondiwindi, Quilpie and Cunnamulla were invited to provide pricing proposals for the delivery of a number of these sites using local suppliers and subcontractors. Proterra Group were successful in obtaining 9 of these sites at a total value of approximately $2.3 million. The aims of this project as nominated by TMR were as follows: • To reduce the fatigue or road users through increased desirability of roadside rest areas on their network • To ensure all rest stops are compliant with accessibility legislation and standards • To attend to rectification and improvement issues identified by Roadtek during Site Audits in 2016 and 2020

PROSERPINE MAIN STREET STREETSCAPE UPGRADE

Whitsunday Regional Council

Whitsunday Regional Council delivered the Proserpine Main Street streetscaping upgrade from September 2019 to September 2020 after 18 months of planning, consultation and design. The works included upgrades to the footpaths, signage, furniture, lighting, landscaping and minor drainage amendments. The project formed part of the Proserpine Masterplan and was intended to attract further visitors who generally pass by on the Bruce Highway. The works tied in with the opening of the new WRC administration building at 83 Main Street, the Proserpine RV park, located on Main Street, and free camping at Lake Proserpine, accessed via Main Street. While the success of the project is hard to measure, it has coincided very fortunately with these other projects and an increased drive market following COVID. Businesses on the Proserpine Main Street have since seen vastly increased customer numbers and the entrance treatments now add further appeal in bringing visitors off the highway. The construction stage was carried out by Council’s internal staff from Roads and Drainage and Parks and Gardens. This allowed for significant savings to be achieved and upskilling of staff on new techniques. The project was initially tendered and received quotes of approximately $6 million with the potential for numerous variations due to many unknowns. By carrying the works out internally the project was able to be delivered for under $3 million, yet still achieved the scope of the design and expectation of the community.

HUGHENDEN 4.3ML TANK CONSTRUCTION

Flinders Shire Council, Wulguru Steel, GHD

The Hughenden 4.3ML Reservoir, Booster Pump Station and Primary Chlorination project involved planning, design and construction of a new 4.3ML welded steel reservoir (19m diameter x 18m height), a booster pump station to service the adjacent industrial estate and primary chlorination system in Hughenden. The project was initially conceived in 2017 following community complaints due to poor water quality and pressure. Following this, Flinders Shire Council engaged GHD to undertake network modelling of areas experiencing insufficient water pressure and to recommend solutions including required water storage capacity for current and future needs. The report identified areas of inadequate water pressure and confirmed operational experience that the existing Hughenden 1.7ML reservoir was at capacity during summer peak demands. The modelling and engineering assessment also advised a new 4.3 ML storage was required which would also cater for the future demand. Additionally, in order to bring Hughenden up to standard with Australian Drinking Water Guidelines, Council needed to install a new automated chlorination system at Hughenden, which was previously undertaken manually on an adhoc basis pending water quality. The final construction project was undertaken in 2020, amidst the global COVID-19 pandemic. The pandemic generally resulted in material shortages and cost escalation nationwide, and caused the township of Hughenden to close to outsiders for a period of close to 4 months. Despite this, the project incurred minimal impact due to the project planning and mitigation methods put in place by the project team, consisting of Flinders Shire Council, GHD and Wulguru Steel.

TUMMAVILLE ROAD BRIDGE REPLACEMENT

Toowoomba Regional Council

The new Tummaville Road Bridge crosses the Condamine River (North Branch) and provides connectivity between Pittsworth and the surrounding areas. The old 5 span timber bridge had reached the end of its useful life and was closed to traffic for more than a year, prior to its replacement. The new Tummaville Road Bridge is a 2 span 2-lane bridge, 8.5m kerb to kerb, with overall length of 38m and a clear height of up to 3m above standing water level. The new bridge has been designed to current Australian Standards with a design life of 100 years. The bridge has an improved flood immunity of Q50. The bridge project management and construction were both self performed by Council teams, using specialist demolition and piling contractors. Otherwise, the bridge was constructed using Council day labour. The bridge is constructed on 21 500mm diameter hexagonal prestressed concrete piles driven to an average depth of 20m. These support 30 transversely stressed deck units, 19m long and weighing 19 tonnes each. The bridge abutments and pier have been designed with a platform to jack up the deck units for laminated elastomeric bearing replacement. The outer deck units include precast castellated kerbs to accommodate use of wide agricultural machinery which provide a safety barrier for traffic but have a lower maintenance cost compared to bridge rail on low volume rural roads. The $2.97 million bridge replacement was jointly funded by the Council and Australian Government Bridges Renewal Program, and provides improved connectivity for local agricultural production.

THARGOMINDAH WATER COOLING PROJECT

Bulloo Shire Council, Peak Services, NRG Services

Bulloo Shire Council (Council) has made significant investment in solar energy installations and the new Thargomindah Water Cooling System (Project). The Project delivers long-term financial and social benefits while reducing risk to Council and the community, continuing their ‘green’ council legacy. Conceived by Council in consultation with Peak Services, and with a 60% funding boost from the Department of Local Government Racing and Multicultural Affairs, the Project was made possible. Council had a challenge like many remote councils; reliance on water supply from bores. Whilst the water quality is potable, without treatment the temperature exceeds acceptable level. The water temperature also degrades existing water supply and reticulation infrastructure. The Project uses reliable technology in an innovative way, without compromising on maintenance and operational ease. Bore water is cooled via plate heat exchangers that are coupled with cooling towers bringing water temperature down from 72 to 35 degrees Celsius. Water is stored in 1.5ML storage tanks and pumped on demand to meet town water supply needs. The bore water is kept separate from the cooling process so that water quality standards cannot be compromised. A final stage UV filter assists to ensure that the water delivered to households meets required quality standards. Using the power of the sun to reduce water temperature seems like an unlikely partnership, but the new solar-powered water-cooling towers have successfully reduced the potable bore water temperature to a cool drinkable level and reduces the degradation of existing water supply and reticulation infrastructure.

PAROO SHIRE COUNCIL DRFA PROJECT

Paroo Shire Council / Proterra Group

Proterra Group were engaged by Paroo Shire Council to scope and deliver their most recent DRFA Flood Restoration event. This was the first event that Council had experienced for many years and chose to use a consultant based approach due to lack of in house resources and recent experience in DRFA Event Management. To deliver the project successfully it was essential that works were delivered using local Contractors and Council Crews to not only bring the infrastructure back to pre-event levels, but maximise the economic gains for the local community who had experienced years of drought and low economic activity in the region. Proterra Group assembled a Project Team inclusive of Project Manager, Site Inspectors and Contract Administrator to deliver the works with a total approved value of $3.3M. This was a difficult project to deliver as Council lacked experience Engineering staff at the time, and there was a severe lack of experienced local contractors to help deliver works. Over the course of the project Proterra Group were able to liaise successfully with Council and local suppliers and subcontractors to build 100% Local teams to deliver the works. This ended up being a combination of Council works crews, and full contract works crews. The project was delivered successfully on time and in budget with a lot of learnings and local capacity building along the way.

MURGON CBD FOOTPATH RECONSTRUCTION

South Burnett Regional Council

The Murgon CBD Footpath Reconstruction Project transformed and regenerated the Central Business District (CBD) of Murgon whilst adding both a depth and connection to the historical and cultural indigenous heritage of the area. This project was initiated by South Burnett Regional Council (SBRC) who had an aspiration to provide a footpath which would allow upgraded, safe and aesthetically pleasing access to the vibrant CBD businesses in the town of Murgon and its community. The Murgon CBD Footpath Reconstruction Project celebrates the regions indigenous culture and traditional history through a carefully designed layout and with the inclusion of artwork that is evident throughout the reconstructed assets. Delivered over three stages, this multi-year project was delivered over three stages and Council strived to minimise construction impacts on the local business community for its duration with practical completion being achieved in 2021. The outcome succeeded in providing both a modern and cultural footpath incorporating associated infrastructure compliance while meeting current engineering standards. This $2.14 million project was co funded through Councils capital program together with a contribution from two rounds of the Works for Queensland Program. Engagement with the local Murgon Business Development Association, business owners, indigenous leaders, Council and residents during the project offered the township an opportunity to revitalise its business operations and CBD access to enhance and entice visitors to the town of Murgon.
