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.

That passion led to a degree at QUT which has armed Kurt with a Bachelor of Civil Engineering, Majoring in Structural Engineering. 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.


Carolina Bernal
Structural Engineer

Hailing from Colombia, Carolina Bernal is a talented structural engineer who is part of Inertia Engineering’s Housing Team.

Working part time, Carolina balances the needs of our clients with the demands of a young family, bringing her enthusiasm, technical skills and expertise to each project she works on.

She specialises in designing solutions for all projects types, ranging from home renovations and new builds to townhouse developments and lightweight structures.

Carolina spent her first three years in Brisbane studying before joining us at Inertia Engineering. In those 5 years, she has loved Inertia Engineering so much she feels the team are more like family than colleagues. Thanks Carolina, we think of you as part of the family too.


Nathan Green
Civil Engineer

Nathan is a civil engineer who specialises in stormwater management and flood modelling. He worked as a civil designer and drafter on the Sunshine Coast, before undertaking his Bachelor of Engineering (Civil). Nathan is particularly interested in urban and land development.

Nathan is passionate about instilling confidence into property owners in flood-affected areas. He keeps owners informed about the risk of flood on their development, through extensive modelling and reporting.

His recent work includes a concept stormwater management design for an education and training facility, set on a 48-hectare site near Toowoomba.


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 Senior Civil Designer who has over 10 years’ experience in the civil engineering field with 8 years spent as a designer. Isaac’s vast project experience includes the design and documentation of industrial and commercial developments, mining, roads and highway projects as well as multi-unit residential developments and land subdivisions ranging from 2 to 100+ lots.

Isaac’s efficient, cost-effective designs have a strong attention to detail while being clearly presented for project stakeholders within identified timeframes. His experience also enables him to present clients multiple options for their projects (where required).


Sarfaraaz Sacur
Civil Project Engineer

Civil Engineer, Sarfaraaz Sacur, joined the team at Inertia Engineering in March, as we continue to build our expertise and capability.

Cutting his teeth in the Flood team, Sarfaraaz is responsible for helping to ensure that our client’s developments can cope with everything that Queensland’s precipitous rainfall can throw at them.

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. This included the Las Arenas development, of one of the most spectacular projects that Barcelona has seen as an old bullring was converted into a shopping centre with 5 levels of basement and 6 levels above ground, including cinemas and a 90m diameter timber dome.

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.


Mick Briais
Site Manager

Understanding a client’s job from under the ground to the finished top floor is what drives Site Manager, Mick Briais’, career at Inertia.

As a qualified geotechnician, Mick has a career spanning 20 years in construction and management across complex sites and environments. From the gasfields of the Surat Basin to the coalfields of the Bowen Basin, Mick has been trusted with the smooth operation and performance of drilling teams and the sites on which they were required to work.

At Inertia, Mick specialises across everything! From medium and high-rise buildings to waste and water infrastructure, if it is on site and Inertia are involved, Mick is there to manage the project and ensure that our clients’ expectations are met and surpassed. Over the past 8 years Mick has specialised in site assessment of structural and civil inspection dealing with medium to large building contractors to ensure high quality construction procedures are followed and maintained.

Originally a Brisbanite, Mick now calls Dayboro home, where he is an active part of the community as a professional part time urban firefighter with Qld Fire and Rescue. As well as being one of Dayboro’s commanding officers, Mick also teaches road crash rescue in various regions of Queensland as part of his belief in giving back to the community


Daley Curran
Senior Civil Engineer

Daley is a new member to the team at Inertia having joined us on the back of a globe-trotting career break that saw him take in North, Central and South America, and much of Europe, a trip the highlight of which was a stint on the Galapagos Islands, complete with the iconic giant tortoises.

Holding a dual degree in Civil Engineering and Business from Griffith University, Daley will work with the Civil Team, specialising in our clients' subdivision and infill projects. His expertise will be crucial to ensuring that even the most complex and challenging sites can be transformed into viable developments.

Originally from the Gold Coast, Daley now calls Milton home, and when he is not heading back to the coast for a surf or hitting the golf course - handicap not stated, watch out for him on Inertia’s golf day - he can be found sampling the city’s growing craft beer scene. A brewer himself, with an IPA and Stout to his name, Daley is hoping to get back into producing his ales.

A request has already been made for an Inertia brew…something with good structure and earthy tones that’s easy to drink and leaves you wanting more.
