Sydney structural and civil engineers.

Grasso Consulting Engineers

Grasso Consulting Engineers is a director-led practice with more than 40 years of experience: demolition engineering on Sydney’s towers and bridges, temporary works and heavy lifting, and the structural design of new buildings across New South Wales and Queensland.

What sets us apart

Every project is looked after by a director, from the first meeting to the last lift.

Director-led

Jim Grasso looks after every project personally. You deal with the engineer who does the work, not an account manager.

Practical design

Properly detailed

Drawings and calculations detailed so that accurate information reaches everyone involved in design development and construction.

Demolition specialists

More than 30 years advising on the demolition of high-rise buildings and bridges. Regular clients include the four major demolition contractors in NSW and Queensland.

Registered and chartered

Fellow of Engineers Australia, Chartered Professional Engineer (CPEng, NER), Registered Design Practitioner – Structural (NSW) and RPEQ in Queensland.
