    THE FORENSIC ENGINE

    Verification at Scale

    CxCheck cross-references contractor scripts against decades of site-proven logic, method statements and global standards. Catching the sequencing errors that manual reviews miss.

    MISSION-CRITICAL RISK MITIGATION: VERIFIED

    Who CxCheck is for

    Independent CxAs and consultants

    You review scripts and sequences of operations alone, with no second pair of eyes on the work. CxCheck reads the full document set and returns a findings report with source references, so you have something to check your own judgement against before it goes out.

    See the Solo tier

    Small consultancies

    Review quality should not depend on who picked up the document. CxCheck applies the same standards library and the same checks to every submission, so a junior engineer and a principal produce comparable review output. Up to five users are included on the Practice tier.

    See the Practice tier

    Project teams

    Contractor, consultant and owner each read the same documents against different assumptions. CxCheck gives the whole engagement one shared review standard and one evidence trail through L0-L6, with unlimited users on the Project tier.

    A commissioning tool built for MEPF work. Purpose-built for mission-critical MEPF systems with AI workflows at its core, CxCheck supports document review and verification through every commissioning level.

    Commissioning review is unforgiving work, whether it lands on one independent CxA or a full project team. From Hong Kong to the Philippines and Thailand, CxCheck combines purpose-built AI review logic with deep MEPF domain expertise to audit sequence of operations, FPT and IST scripts and MEPF submittals. It is designed to help you catch human error earlier, reduce avoidable project delays and keep evidence organised through every commissioning level. Deployment is available as a hosted workspace or, for approved enterprise environments, as a customer-controlled private node.

    INFRASTRUCTURE

    A Sovereign Service.
    Stated plainly.

    CxCheck is built as a sovereign service. Document analysis runs on hardware we own and control - your documents are never sent to third-party AI providers and are never used to train public models. For approved enterprise projects, CxCheck can be deployed on dedicated hardware inside your own facility.

    Sovereign Hosted

    Available now - the standard service

    • Document analysis runs on inference hardware CxCheck owns and controls, using locally hosted models.
    • No third-party AI provider - OpenAI, Anthropic, Google or any other hosted model API - ever receives your documents.
    • Project records and uploads are encrypted in transit (TLS) and at rest, isolated per organization by row-level security and role-based permissions.
    • Your documents are never used to train any model and are never shared with third parties.

    On-Site Node

    In development - approved enterprise projects

    • Dedicated hardware supplied pre-configured and operated inside your own facility, licensed on a subscription basis.
    • Documents are stored on that node and inference runs on it, inside your network boundary.
    • This tier is not how standard customers are served. It is scoped per engagement and subject to technical review and a signed agreement.
    • Talk to us before assuming a project qualifies - we confirm in writing what runs where.

    No Third-Party AI

    Your documents are never sent to OpenAI, Anthropic, Google or any other hosted model API and are never used to train public models.

    Hardware We Own

    Document analysis runs on inference hardware CxCheck owns and controls, not on a rented general-purpose model service.

    Audited Access

    Per-organization isolation, role-based permissions and an audit trail record who accessed or changed project records.

    About the Founder

    Blue-Chip Commissioning Leadership

    Craig McMahon is a dual UK-Filipino Senior Commissioning Manager with over 15 years of leadership across Hong Kong and South East Asia. He applies international UK and Hong Kong commissioning standards to the most complex, security-sensitive projects in the region delivering financial institution commissioning, data center security compliance and MEPF audit automation at the highest level.

    Craig has led and consulted on commissioning operations for security-conscious organizations across tier-one financial institutions, integrated resorts and mission-critical data centres. His sector expertise spans Mission Critical Data Centers, Tier 1 Financial Institutions, Integrated Resorts & Casinos and International Travel Hubs.

    The Security Manifesto

    Craig's professional directive is unequivocal: commissioning teams must never upload sensitive designs or test data into cloud-based AI. Because Security Systems and FDAS (Fire Detection and Alarm Systems) fall directly under the commissioning scope, moving this data to external servers creates a catastrophic physical and digital security risk. Proprietary facility blueprints in the wrong hands represent a permanent vulnerability to the asset and its occupants an exposure that cannot be reversed.

    The CxCheck Approach: Controlled Data Handling

    Craig built CxCheck as a sovereign service. Document analysis runs on hardware we own and control - your documents are never sent to third-party AI providers and are never used to train public models. Project records and documents are stored under per-organization isolation, encrypted in transit and at rest and readable only by the people you invite to a project. For approved enterprise projects, CxCheck can be deployed on dedicated hardware inside your own facility. Which mode applies is agreed in writing before onboarding.

    Frequently Asked Questions

    How does CxCheck handle data center project privacy?

    The hosted workspace stores project records in a managed cloud database with row-level security, so every row is scoped to your organization and readable only by users with an authorised role. Documents are held in access-controlled object storage, encrypted in transit and at rest and are not used to train public AI models. A customer-controlled private-node deployment is available for approved enterprise environments.

    What specific errors can the AI identify in commissioning reports?

    The engine is tuned to detect MEPF testing inconsistencies, including redundancy gaps, testing criteria discrepancies and missing site acceptance/functional performance test data that human reviewers might overlook.

    Is this tool optimised for the SE Asia market?

    CxCheck is built around international commissioning standards, so it applies to data center and commercial building projects in any location - including SE Asia, where our team works day to day. Local codes and project-specific standards can be added to the reference set used during review.
