Joshua Falco
Structural Engineer

Writing bios for websites isn’t Joshua Falco’s thing, so let’s look at what he does best - solving the engineering problems that others put into the too hard basket.

From large scale retail, commercial and defence projects through to education and residential developments, Joshua brings his 10+ years of experience to Inertia Engineering’s Buildings Team.

Where he really excels is in adapting existing structures, efficiently, thoughtfully and in a way which makes economic sense for all parties.
Want to add 35 storeys to your existing multistorey building? Or maybe you wish to sympathetically rejuvenate a historic building, to give it a new lease of life and retain its character and charm? These are the projects Joshua does best and where he helps Inertia Engineering’s clients.


Kurt Annand
Structural Engineer

Brisbanite, Kurt Annand, is a new member of Inertia, joining us in the structural team. With over 15 years experience, Kurt originally started his career straight from school as a cadet draftsperson, where he found a passion for the projects he worked on.

Kurt has built a successful career helping to design, plan and implement numerous large-scale retail, commercial and hospitality projects such as Pacific Fair, The Calile Hotel, The Rocket Robina and Coomera Shopping Centre. He will bring this experience, technical know-how and knowledge to further grow this important and growing sector for Inertia.

Like any engineer, Kurt likes the details many miss out on, but unlike most he commits a myriad of facts and figures to memory, which immediately mark him out as a dark horse for Inertia’s Trivia Competitions. Given the serious nature of trivia at Inertia, Kurt will be a highly popular and prized team member.

Daniel Gibson
Civil Engineer

We like to think our team at Inertia Engineering have superpowers and in the case of Daniel Gibson it could well be true. Daniel has a unique ability to ensure the Inertia team get their daily caffeine fix safely and quickly – his superpower is parting the traffic on Sandgate Road so that our Inertians can cross the daily snarl.

Just think, if Daniel can part the traffic on Sandgate Rd each day, what he can do for your projects? Well, Daniel can bring his drive, passion and increasing portfolio of skills to bear, ensuring that your projects are delivered to the highest standards. Working in the civil engineering team and specialising in water and wastewater design, he is heavily involved across all project sectors from industrial, commercial, residential, townhouses, retail, property developments and high-rises.

As he develops his career, Daniel is keen to grow his skill set and learn as much as he can, as quickly as possible and make a valuable contribution to every project he works on.

And remember, if you are ever at Inertia Engineering and you need a coffee, wait for the Sandgate Moses to make his move and cross in his wake.


Isaac Ernst
Senior Civil Designer

Isaac is a civil designer who specialises in in-fill developments. His project experiences ranges from small townhouse developments to major high-rise infill projects. He works closely with the Building team during a development’s structural design stages to foresee any potential civil design issues.

In a city crisscrossed with creeks and prone to flash flooding, Sarfaraaz provides modelling, design and documentation of water, sewer and stormwater for developments such as townhouses, small subdivisions, residential houses, commercial and industrial use developments.

Liaising with councils, architects, town planners and clients are part and parcel of his role and in a complex environment, Sarfaraaz is rapidly becoming an expert in design standards, policies and codes of local councils.


Emily Boone
Structural Designer-Drafter

Emily has over 10 years’ experience in the construction industry and joined Inertia in 2017.

Since starting out as a cadet structural draftsperson, Emily has committed to engineering for life and is now in the 2nd year of civil engineering degree at QUT, where she will become a ‘real world’ structural engineer.

Emily is involved in our residential and commercial projects, working with the team across every aspect of the design process. As Emily’s career develops at Inertia, her focus will be on winning over clients and expanding her skills and project portfolio.

Emily doesn’t think that we need to know that she likes motorbikes, old buildings with character and wine…but we do. So, when you bump into Emily ask her all about them!


Kai Xu
Structural Designer-Drafter

Kai Xu joined as a structural designer-drafter in July 2017.

If we think Brisbane is growing, what we are seeing is nothing to the first-hand experience Kai gained working for one of China’s top design companies in Beijing.

With a skillset developed across industrial, commercial, residential and public buildings, Kai is committed to delivering design solutions that are underpinned by his rich experience, knowledge and skills.

We’re delighted that Kai has decided to call Brisbane home and look forward to working with him to bring his experience of the Chinese construction boom to the growth of Brisbane and South-East Queensland.


Ed Pigozzo
Graduate Engineer

Originally from Treviso, a small town near Venice, Ed moved to Australia when he was six weeks old and brought with him his Italian heritage which comes out in his love of soccer, cold crisp beer and Italian food.

As a recent graduate from QUT, Ed holds a bachelor’s Degree in civil and Structural Engineering and worked with us in his final year at Uni before coming on board as part of the structural buildings team as graduate engineer.

Ed’s focus is on continuous learning and he is heavily involved in researching and scoping the latest programs, design ideas and methods that can be integrated into his skillset for use on the varied projects he is working on.

Day-to-day, Ed is involved in design, review and project co-ordination as he works with members of the project team to deliver outstanding results for our clients across projects in the residential, commercial, childcare and industrial sectors.

When he’s not helping our clients, you’ll find Ed cheering on the mighty Roar at Suncorp Stadium or glued to a TV in the small hours catching up on the Champions League, Premier League, Serie A or the World Cup. And if he is not watching it, he is playing six-aside for his uni team or turning out for Inertia’s Futsal Team, Young Man United. And if that isn’t enough, Ed is a Tae Kwon Do instructor training students twice a week in the discipline and skills of self-defence.

Given all the energy Ed burns, it probably explains why he is on first name terms with the local Subway.


Ramon Gimeno
Senior Structural Engineer

Senior Structural Engineer, Ramon Gimeno joined the Inertia in September 2018 adding further depth and experience to our structural team.

Originally from Sadabell in Catalonia, Spain, Ramon started his career in Barcelona working on large scale commercial developments including office and entertainment projects.

Since relocating to in Australia in 2012, Ramon and his wife had a spell in South Australia before realising the error of their ways and heading back to the sunshine state where the camping, fishing and four-wheel driving is far superior.

A keen cyclist, and former competitive rider you’ll often find Ramon whizzing along the city’s bikeways as he speeds into the city on his daily commute.

Holding a Masters in Structural Engineering and an Architecture degree, Ramon is keen to bring his skills and experience to a diverse range of projects on behalf of our clients.

Abdulkadir Abdoola
Graduate Civil Engineer

Originally from Zimbabwe, Abdulkadir has called Australia home since he was six years old and when he is not helping our clients with their water engineering, you will most likely find him exploring the great outdoors.

With a love of the camping, fishing, 4-wheel driving, and exploring every corner of the Sunshine State, if there is a out of the way spot on the beach or in the bush, he will be there.

Holding a Bachelor of Engineering from QUT, with a second major in Structural Engineering, Abdulkadir specialises in sewer and water planning, stormwater modelling and design, flood assessments, and engineering reports and is a key part of assisting our clients to achieve and understanding of challenging sites and the requirements to obtain potential development approval.
