SJA was established in 1999 by Founder and Construction Expert, Steve Abbott. With a hands-on background in construction, Steve began his career “on the tools” and steadily rose through the ranks to lead some of the most prominent and high performing construction teams in Australia. Throughout his leadership in the field, he encountered recurring challenges stemming from a limited and often inadequate supply of critical project services, issues that consistently jeopardised timelines, budgets and the overall success of developments.

Motivated by a desire to transform the industry, Steve founded SJA to deliver a new standard in project delivery services. Drawing on his deep industry knowledge and practical experience, he built a company capable of offering the comprehensive and specialised support necessary to ensure projects not only succeed but reach their full potential. From the outset, Steve also instilled a culture that became foundational to the organisation, centred on excellence, autonomy, personal growth and an unwavering commitment to doing what is best for the client. This ethos quickly became an integral and sacrosanct part of SJA, shaping the way its teams operate and the way the company partners with clients.

Since its inception, SJA has grown into a respected and reliable project delivery partner. Today SJA comprises a global team of highly skilled and qualified professionals committed to helping clients achieve their vision through smarter planning, execution and delivery of projects. This growth has been supported by a working environment that empowers people with genuine autonomy, encourages professional development, and reinforces a collective responsibility to deliver excellence across every project. The culture remains one of the company’s greatest strengths, consistently driving high performance, accountability and a client first mindset.

In 2022, SJA became part of the RSK Group, a global leader in the delivery of sustainable solutions. With over 240 environmental, engineering and technical services businesses in its network, RSK offers unrivalled expertise and a fully integrated offering from research and consultancy through to on the ground implementation. This partnership enhances SJAs ability to provide practical, future focused solutions to some of the most complex challenges in the construction and infrastructure sectors, while ensuring the cultural foundations continue to guide the business. The values of excellence, autonomy and personal growth remain deeply embedded, supporting a unified commitment to delivering the best outcomes for clients.

Today, SJA is led by Managing Director Mark Lincoln, who continues to build on the strong foundations established by Steve Abbott, ensuring the company remains focused on excellence in project delivery and client partnership. Under Marks leadership, SJA remains firmly committed to the cultural principles that have defined the organisation since its beginnings and that continue to support its people and clients in achieving exceptional outcomes.
