Value through collaboration
Integrated design and build approach.
What sets Sirius Geotechnical apart from traditional ‘pure play’ consultancies is our fully integrated design and build service. By working directly with Sirius’ in-house teams for earthworks, remediation, demolition, and civil engineering, we gain a deeper understanding of what is physically achievable on site. This insight allows us to identify value engineering opportunities and offer practical solutions that streamline the development process.
Our collaborative approach ensures that our clients receive not only expert advice but also the benefit of real-time, on-the-ground experience that enhances project outcomes.

We continuously invest in training and mentoring to develop our team’s skills, with many of our staff working toward or achieving chartership with recognised professional institutions.

Our goal is to reduce development uncertainty early in the project life cycle, delivering the right advice the first time. We build strong relationships based on trust and clear communication, ensuring that our clients’ needs are met, and their projects move forward without unnecessary delays or complications. Sirius Geotechnical is committed to helping our clients succeed by providing expert advice and innovative solutions.
Contact UsA Phase 1 Desk Study includes historic map reviews, environmental records, and a site walkover to identify potential contamination and geotechnical risks. Sirius creates comprehensive Preliminary Conceptual Site Models (PCSMs) to inform further investigations.
A Phase 2 investigation involves drilling, sampling, groundwater testing, and risk assessments. Sirius tailors investigations to your site’s needs, including Generic Quantitative Risk Assessments (GQRA) to inform remediation or design.
A Remediation Strategy outlines how contamination risks on a site will be mitigated. Often required for planning, it follows findings from Phase 1 and 2 site investigations. Sirius prepares effective strategies with clear validation steps and delivers Regulator-approved remediation solutions.
