What Norman Disney & Young does

Norman Disney & Young (NDY) is a privately held Australian building services engineering consultancy founded in Melbourne in 1959 and operating as a wholly-owned subsidiary of US-based Tetra Tech. The firm delivers multidisciplinary engineering and advisory services across mechanical, electrical, hydraulic, fire protection, vertical transportation, ICT, security, controls, acoustics, lighting, structural and civil disciplines, supported by specialist capabilities in BIM, computational fluid dynamics, parametric modelling, smart building integration, and sustainability certification (Green Star, NABERS, WELL, LEED, GRESB). Its service portfolio spans more than 35 distinct areas, delivered through an integrated single-firm model with two wholly-owned sub-brands: Engineering Commissioning Services (ECS) for independent commissioning management and NDYLIGHT for specialist lighting design.

NDY serves enterprise clients across the building lifecycle — architects, asset owners, contractors, developers and government entities — with particular depth in sports and entertainment venues (Suncorp Stadium, Gabba, Coopers Stadium, Sydney 2000 and Gold Coast 2018 venues, Brisbane 2032 Olympic pipeline), healthcare and life sciences (CSL Seqirus Project Banksia, State Health Operations Centre), data centres, aviation, education, and commercial real estate. The firm operates from twelve offices across Australia (Adelaide, Brisbane, Canberra, Gold Coast, Melbourne, Perth, Sydney), New Zealand (Auckland, Wellington), the United Kingdom (London), Ireland (Dublin) and Canada (Vancouver), and executes projects globally through the Tetra Tech network.

Revenue is generated through project-based professional consulting fees negotiated on scope, complexity and client requirements, with no publicly disclosed pricing. The go-to-market is enterprise field sales via direct client engagement and competitive tendering, supported by thought-leadership content, project case studies, industry events, and a LinkedIn-led social presence. NDY has held carbon neutral status since at least 2023, became a World Green Building Council Net Zero signatory in 2023, and earned the WELL Enterprise Provider designation in 2024, positioning the firm as a sustainability-credentialed partner for owner-side decarbonisation mandates.
