If your data-centre package includes cooling pipework, cable containment and life-safety routes, identify the support requirement for each service before choosing a support. The services may share a corridor or frame, but their duties and fire requirements are not automatically the same.
The fire question also includes the structure carrying the service. A cable tray or pipe depends on the brackets, bearers, frames, rods, connections and fixings that hold it in place. The support needs a design basis that matches the service route and the building attachment.
Steel loses strength and rigidity as it heats. Channel can deform or buckle, and a connection or fixing can affect whether the service stays supported. A product description on its own does not show how the assembled support will perform.
A data-centre design package can include different types of M&E route. Cooling pipework may have a different purpose from a cable route serving life-safety equipment. Do not use one general fire statement for all of them. Ask the project design team to state which service needs support in fire, what function it must maintain and for how long.
Once the service requirement is clear, trace the physical support path. Mark the containment or pipe, the bracket or frame, the bearer, the connections, the vertical support and the building fixing. This is the detail the designer must assess and the installer must reproduce.
Before procurement, record what each support carries and the fire condition it must address. For cable containment, show the tray, ladder or basket, the cables carried and the support points. For pipework, show the pipe route and support type. For life-safety cable routes, identify the required circuit function and duration from the project design.
Then share the details needed to design the support: service arrangement, support geometry, spans, connections and building attachment. If several services share a support, show which services sit on each bearer or level. The positions and connections affect the arrangement, so a drawing with only a general support symbol may not give enough detail for assessment.
This information helps the designer compare the proposed support with the evidence. It also makes site checks more straightforward. The installer can compare the channel, rod positions and connections with the drawing before loading the support with services.
When a route changes, check whether the support design still matches. A new service, a changed bearer position, or a different connection can alter the support. Send the change to the responsible designer and retain the revised drawing and report with the installation record.
Bring the support question into coordination while the service routes and support positions are being agreed. Check where supports can attach to the building and whether the proposed frame or bracket fits the space available. Record any constraints that affect the section, connection or support position.
If cable containment and pipework share a support, show the relationship clearly. Identify the services on each level and the connection between the bearer and frame. If the routes use separate supports, show their positions and building attachments. The assessment needs to follow the physical load path, not a generic symbol.
At a design review, ask whether the proposed arrangement stays within the evidence or needs a separate calculation. If work is already installed, record what is present before relying on a design. Photographs and marked-up drawings can help describe the support, but they do not replace the report or assessment.
This early record is useful when the project team reviews procurement substitutions or site changes. A different channel, bracket or connection may look similar but still change the support design. Ask the responsible designer to review the changed detail before relying on the earlier evidence.
Use a marked-up coordination drawing to show the support reference at each location, the services carried at each level and the route to the building fixing. Add the relevant design reference beside each support type. That gives procurement a clear schedule to check against and gives the installer a drawing to follow on site. If one support carries several services, identify them on the same detail so a later change to one route is visible to the team reviewing the support.
Where a shared frame serves more than one package, agree who provides each connection and who checks it before the next service is installed. Record the support reference on the inspection sheet and match it to the drawing revision. If the routes are installed in stages, update the support schedule when a service is added or moved. This gives the site team a clear point to request design review before a later change is built into the frame.
Some MX channel supports have fire test evidence under EAD 280016. "EAD-tested" applies only to MX channel within its tested scope. Check the support type and connections against the report. Do not carry that wording across to every channel arrangement.
Where the required support type or service arrangement sits outside the appropriate channel route, custom steel may be considered. MIDFIX assesses fire resistance for custom steel supports using EN 1993-1-2, with serviceability checked using EN 1990 and EN 1991 load combinations. The calculations apply to the designed support and its stated assumptions.
A hybrid design may combine a custom steel frame with channel bearers. The drawing should show how the parts connect and which route the design follows. Whether the support uses channel, custom steel or a hybrid, the evidence needs to match the physical support being installed.

The report should identify the support assessed, its design basis, the assumptions and the limits that apply. The drawing should give the installer enough detail to place the supports and connections as designed. Keep the report and drawing with the project record so the installation can be checked at review and handover.
At site review, compare the actual support type with the schedule before services conceal the details. Check the position of the support, the connection to the bearer and the building attachment. If a substitution has been made, do not rely on visual similarity. Ask the designer to confirm whether the revised parts and geometry still match the report. Keep the response with the final drawing so the handover record explains what was installed.
FRS covers the support arrangement. It does not establish the fire performance of the services or the building structure. The fire strategy and system requirements remain part of the project design. Keep those decisions with the relevant design team and make the support requirement clear to the support designer.
For life-safety cable routes, read BS 8519 and cable supports. For the difference between a fire test and a broad product claim, see fire tested vs fire rated. For an overview of the service, see the FRS page. For standards context, see fire standards for M&E supports.
FRS can assess support arrangements for M&E services such as cooling pipework, cable containment and life-safety routes. The fire requirement and support design need to match each service.
Not necessarily. The project design team should state the function and fire requirement for each service route before the support is selected.
No. "EAD-tested" applies only to MIDFIX MX channel within its tested scope. It does not cover every channel configuration or the separate custom steel route.
Consider custom steel when the required support type or service arrangement sits outside the appropriate channel route. The designed support is assessed using EN 1993-1-2 for fire resistance.
