Learn About Our Services

  • As a Client-Side Commissioning Authority (CxA), we work collaboratively with you to oversee and guide the principal contractor and subcontractor teams, ensuring a seamless commissioning process.

    We provide rigorous oversight and collaboration with your project team, ensuring that your MEP building systems are fully optimised, functional, and compliant with all specifications. From concept to completion, we guarantee that the space meets your exact performance, safety, and efficiency standards.

  • We work alongside your principal contractor, taking a hands-on approach with subcontractors and the build team to ensure seamless, efficient, and high-quality commissioning of MEP systems. Our expertise guarantees that your project is delivered as a high-functioning, optimised space, meeting all performance, safety, and compliance requirements.

  • A successful commissioning process starts with a meticulous review of design documentation to ensure that systems are commissionable, functional, and fully integrated within the building. Our Commissionability Review identifies potential design, scheduling, or operational conflicts early, reducing costly rework and ensuring a seamless commissioning process.

  • Ensuring the highest standards of quality in both materials and workmanship is critical to delivering a high-performing, long-lasting built environment. Our QA/QC process provides detailed oversight, ensuring that all materials, installations, and system integrations meet or exceed industry and project-specific standards.

  • We provide retro-commissioning services for existing buildings, delivering expert analysis to enhance efficiency, optimise system integration, and improve overall performance. By evaluating current operations and identifying areas for improvement, we help building owners and facility managers fine-tune their systems to reduce energy consumption, lower maintenance costs, and extend equipment lifespan. Our data-driven approach often results in operational savings of up to 30%, making buildings more cost-effective, sustainable, and comfortable for occupants.

  • We conduct comprehensive validation and diagnostic analytics to assess and document a building's performance and its integrated systems. Our process ensures that all services operate efficiently, reliably, and in alignment with their intended purpose. By leveraging data-driven insights, we identify potential issues, optimise system functionality, and enhance overall building performance. This approach not only improves operational efficiency but also helps prevent costly failures and ensures long-term sustainability.

  • We provide specialised commissioning services to ensure buildings are designed, constructed, and operated with sustainability at the forefront. Our process focuses on optimising energy efficiency, reducing environmental impact, and enhancing indoor air quality. If your goal is to achieve specific sustainability certifications—such as LEED, BREEAM, or WELL—we offer the monitoring, evaluation, and documentation necessary to meet accreditation benchmarks. Our expertise helps clients create high-performance, environmentally responsible buildings that align with both regulatory standards and long-term sustainability goals.

  • Our remote witnessing service offers round-the-clock, off-site commissioning, designed to minimise the carbon footprint of your project while ensuring seamless system performance. By leveraging advanced digital tools, we provide real-time monitoring, validation, and optimisation of building systems without the need for extensive on-site visits. This approach not only supports sustainability goals but also enhances efficiency, streamlines compliance, and reduces travel-related emissions.
