03 / ABOUT CONEX
Founded in 2015 as a specialist carpentry and joinery business, Conex Limited has grown into a construction and fire safety contractor serving London and the South East.
Our work spans Fire Safety, Refurbishment and New Build. Our directly employed teams work with clients and residents to coordinate specialist packages and complete the works safely.
We work with clients, project teams and suppliers to establish the scope, resolve interfaces and plan the installation sequence. Our approach places emphasis on quality, traceability and accountability, from the first review of project information to the final handover.
From concealed construction to the visible finish.
Defined scopes and straightforward communication.
Responsible working and respect for the site environment.
04 / HOW WE WORK
A delivery approach built around the specification, the site and the information needed at handover.
Review the brief, drawings and existing conditions. Clarify scope and responsibilities.
Plan access, procurement and sequencing. Resolve interfaces before installation.
Carry out the agreed works, inspect the details and keep project information organised.
Review the completed package, address outstanding items and bring the relevant records together.
DIGITAL QUALITY & PROJECT MANAGEMENT
Conex uses Onetrace for fire-door surveys and firestopping records, and Procore for project management and delivery.
Material records, inspection evidence and approval workflows support the survey and fire protection packages. Reporting by material type, quantity and dimensions provides accountability through the quality process.
A central platform for drawings, specifications, RAMS and project documents. Inspections, observations and corrective actions sit alongside RFIs, submittals and progress records, creating a digital audit trail of decisions and completed works.
SUPPORTING YOUR PROCUREMENT

Include the location, the type of work, approximate quantities and target dates. Drawings, surveys, specifications and schedules help us understand the package.
