Renzo Tonin and Associates

What Renzo Tonin and Associates does

Renzo Tonin & Associates (RTA) is an Australian specialist engineering consultancy founded in 1982 that delivers acoustic, noise, vibration, sound quality, and structural dynamics services. It is headquartered in Surry Hills (Sydney) and operates from five Australian offices — Sydney, Melbourne, Brisbane, Gold Coast, and Canberra — plus international offices in Kuwait City and Singapore. RTA serves architects, engineers, planners, environmental consultants, developers, builders, and government agencies across infrastructure (rail, road, ports, airports), buildings (commercial, residential, studios), industrial and mining, and legal/expert witness work, and holds Authorised Engineering Organisation (AEO 122) status with the NSW Transport Asset Standards Authority, AAAC membership, and a wholly-owned Kuwait subsidiary.

The firm's core technology stack combines proprietary hardware and software with established third-party acoustic modelling tools. Its flagship RONDA (ROad Noise Data Acquirer) trailer is described as a world-leading system for concurrent CPX and OBSI tyre-pavement noise measurement on two wheel paths. RTA also operates the NATacoustics in-house calibration laboratory and is the Australia and New Zealand distributor of DataKustik's CadnaA, CadnaB, and CadnaR environmental noise modelling software, supplementing its own Gatewave construction noise and vibration modelling platform. It uses ODEON, EASE, and SoundPLAN for 3D acoustic modelling of studios and performance spaces. Notable project credentials include Sydney Metro Northwest/Waterloo/Gadigal, the $470M Rouse Hill Town Centre, Library at the Dock (Australia's first public 6-star Green Star building), Forte (world's tallest timber apartment building), and 180 Brisbane.

RTA makes money as a professional services firm on a project-based consulting model, with fees tied to scope, complexity, and duration of engagement; the company does not publish pricing. Go-to-market is sales-led, driven by industry reputation, AAAC professional membership, participation in industry conferences (e.g., AAS, AAAC AGM), technical case studies, and direct business development to government and tier-one construction clients. The firm was acquired by UK-based RSK Group Limited in 2024, giving it access to a global environmental and engineering services platform.

Core offering

Renzo Tonin & Associates is an engineering consultancy providing acoustic, vibration, sound quality and structural dynamics consulting services for infrastructure, architectural, environmental and industrial projects. The firm delivers projects from concept to completion, including analysis, assessment, documentation and certification, supported by proprietary technology such as the Gatewave software, RONDA noise measurement system, and the NATacoustics calibration laboratory.

Product overview

Renzo Tonin & Associates operates as a full-service acoustic consultancy offering professional services rather than a traditional software product company. Their core offerings include Gatewave (proprietary construction noise and vibration management software), RONDA (specialized road noise measurement equipment), and acoustic consulting services across all building and infrastructure sectors. They also distribute CadnaA/CadnaB/CadnaR acoustic modelling software in Australia and New Zealand, and provide laboratory services through their NATacoustics facility.

Direct peers

• Arup Acoustics: Global engineering consultancy with a dedicated acoustics practice delivering building, environmental, and infrastructure noise services. Directly comparable in technical scope, though backed by a much larger global firm.
• Marshall Day Acoustics: Leading Australasian acoustic engineering consultancy with comparable services in building acoustics, environmental noise, and transport acoustics. Closest direct competitor given similar geographic footprint and AAAC membership.
• Resonate Acoustics: Australian acoustic consultancy providing noise, vibration, and acoustic design services across building, transport, and environmental sectors. Mid-sized direct competitor with similar client base and ANZ geographic focus.

Broad incumbents

• Arcadis: Global design and consultancy firm with acoustics services integrated into property and mobility practices. Overlaps with RTA on rail, road, and building acoustics projects in Australia and Asia-Pacific.
• Wood Group: Global engineering consultancy with environmental noise and industrial acoustics capability. Competes for industrial and resource-sector acoustic mandates that overlap with RTA's mining and industrial segments.
• GHD: Australian-headquartered engineering, environmental, and construction services firm with acoustics capability. Directly competes for Australian infrastructure and building acoustics mandates from the same government and developer clients.
• WSP: Global professional services firm with acoustics, noise, and vibration teams operating across property, transport, and environmental markets. Overlaps with RTA on road and rail noise consulting engagements.
• AECOM: Global engineering and infrastructure consultancy with acoustics capability embedded within larger transport, environment, and buildings practices. Competes for the same major infrastructure mandates as RTA but offers bundled services.
• AtkinsRéalis (formerly SNC-Lavalin): Global engineering services firm with acoustics and rail noise capability. Competes for major transport acoustic mandates similar to those won by RTA (e.g., Sydney Metro, Queensland transport projects).
• SLR Consulting: Global environmental and advisory consultancy with noise and vibration practices. Competes with RTA on environmental noise impact assessments for infrastructure and resource projects.
