New-Construction Pathways and Firestopping
Low-voltage cabling depends on spaces and pathways that often belong to other trades. TekRoute turns device, outlet, backbone and room counts into coordinated sleeves, conduit, tray, backboxes and firestop details with clear inspection and ownership checkpoints.
Treat components, installation and evidence as one system
Choose a supported architecture from application, capacity, environment, pathway, lifecycle and acceptance requirements—not a single part number.
Design inputs and trade coordination
Count outlets, devices, access points, cameras, displays, controls and backbone routes by floor and zone. Include cable outside diameter, bend, pulling and segregation needs and realistic growth.
Coordinate reflected ceiling, architectural, structural, electrical, mechanical, fire protection and furniture plans. Resolve beam, duct, light, sprinkler and access conflicts before conduit or tray is installed.
Carry the counts into a materials list that includes support hardware, sleeves, firestop devices, grounding and the spare capacity the owner asked for, not only cable and conduit footage. Recheck that list after each drawing revision, because a moved wall or an added device changes pathway fill long before anyone is ready to pull cable.

- Trade overlay and clash review
- Growth and spare capacity
- Rated assembly inventory
Pathway, room and firestop engineering
Size conduit, sleeves, tray, J-hooks, pull boxes and backboxes from code, standards, manufacturer limits and the actual cable set. Limit bends and provide accessible pull points. Maintain rated cable support rather than laying cable on ceilings or other services.
Identify each rated wall and floor assembly and select a listed firestop system matching opening, sleeve, penetrant type, fill and movement. A generic red sealant is not a complete design. Define who installs, labels and inspects firestop.
Firestop is where substitution bites hardest: a sealant swapped on site puts the penetration outside the listed system it was drawn to, and the inspector reads the listing rather than the intent. Hold the same discipline on sleeves, tray and hangers, and size telecom rooms for rack access, heat and the fill that arrives with the next remodel.

| Hold point | Verify before | Evidence |

| Room ready | Racks/cable arrive | Acceptance checklist |
| Closeout | Turnover | As-built schedule |
Rough-in inspection and cable readiness
Inspect routes before concealment for size, continuity, bushings, pull strings, bend, support, separation, accessibility and obstruction. Photograph every critical pathway and penetration with location context.
Verify telecom rooms have accepted walls, doors, grounding, power, cooling, lighting, sleeves and rack zones before cable delivery. Track blocked, damaged or unapproved routes as construction issues, not field-installation assumptions.
Decide before the walls close what counts as an accepted pathway and who signs it, so the photo set has a purpose beyond decoration. Name images by room, level and penetration, keep punch items for blocked or undersized routes with a responsible contractor against each, and set the date that route will be reinspected.

Closeout, labeling and future penetrations
Deliver pathway and sleeve schedules, room plans, firestop systems and labels, inspection photos, deviations and capacity. Mark abandoned or spare sleeves and seal them appropriately.
Control later penetrations through an approved permit and firestop process. Update fill and as-builts after additions and prevent other trades from using reserved telecommunications pathways without coordination.
The record that survives this job is the sleeve schedule with remaining fill and a firestop label index tied to photographs, handed to whoever runs the building afterward. Include the permit form for later penetrations, reconcile labels against the as-builts one last time, and keep route drawings out of general circulation once the building is occupied.

How we plan and deliver the work
The final design depends on site conditions, existing systems, client policies and the selected manufacturer or platform.
Count and route
Convert outlet, backbone and room counts into sleeve, conduit and tray sizes along a coordinated route.
Coordinate penetrations
Mark wall and floor penetrations with the other trades and pick a firestop detail for each condition.
Inspect rough-in
Walk empty conduit, sleeves and backboxes for bend radius, support and reamed ends before any cable is pulled.
Seal and label
Install the firestop to its listed detail, label each penetration and photograph it for the record.
Information to gather before design
Pathways are built by other trades before any cable exists, so counts and fill assumptions must be settled while routes are still on paper.
- Outlet counts by floor and room
- Wall and floor assembly ratings
- Ceiling type and plenum status
- Planned growth for spare pathway
- Trade responsible for each sleeve
Frequently asked questions
These are common planning questions. A site-specific answer should be confirmed during discovery and design.
Can firestop be selected by sealant color?
No. Use a listed system matched to the assembly, opening and penetrants.
Who owns pathway conflicts?
Define trade responsibility in coordination documents and resolve conflicts before concealment.
Why inspect empty conduit?
It can be blocked, crushed, over-bent, missing bushings or lack usable pull access.
What should be photographed?
Critical routes, concealed supports, sleeves, firestops, room entries and approved deviations.
Manufacturer software, firmware and technical files remain on the manufacturer’s official website. We do not mirror firmware files locally.
Coordinate Pathways Before the Walls Close
Every penetration through a rated wall or floor has to be firestopped to match the assembly it passes through, and that work gets inspected. Send floor plans, outlet counts and the rated wall locations, and bring us in alongside the electrical and mechanical trades.
