The cost of an office LAN installation can vary widely from one office to the next, even when headcount is the same. From the Techarg team's experience in the field, the difference almost always comes from the number of network points, the cable routes and the class of equipment chosen. In this article we share the cost components we usually walk through during consultations, and how we calculate requirements before preparing a quotation.
Office LAN Installation Cost Components
During a consultation, our team usually breaks the budget down into the following components so that every figure has a clear origin.
| Component | What drives the cost |
|---|---|
| Network points | Number of desks, printers, IP phones, cameras and access points |
| Cabling | Type (UTP Cat6 or fiber optic) and total length |
| Cable routes | Through the ceiling, walls or raised floor, or whether conduit/trunking is needed |
| Switches | Port count, PoE support, and managed or unmanaged class |
| WiFi access points | Floor area, number of floors and number of concurrent users |
| Firewall/router | Number of users, VPN requirements and security features |
| Rack and patch panel | Rack size and number of termination ports |
| UPS | Power draw of the network equipment and the backup time required |
| Labor | Cable pulling, termination, configuration, testing and documentation |
How We Calculate Office LAN Installation Cost
This is the sequence our team follows when mapping out an office's network requirements.
1. Counting the network points
We start with the office floor plan. Every desk that needs a cable is counted, then printers, IP phones, CCTV cameras and access points are added. On every project, we recommend a reserve of about 10–20% for new hires, because adding points after the ceiling is closed is usually far more expensive.
2. Estimating cable length
Our team measures the distance from the rack location to each point along the actual cable route, not in a straight line. For UTP cabling, the recommended maximum distance from switch to device is 100 meters. Beyond that, the solution we usually propose is fiber optic or an additional switch.
3. Determining the switch port count
The port count should at least match the number of network points, plus ports for uplinks and spares. Where there are access points and IP cameras, we recommend PoE switches so those devices do not need separate power adapters, which keeps the installation tidier and reduces the number of power outlets needed.
4. Planning the WiFi
One access point is often not enough for a full floor, especially with concrete walls or many users. That is why access point placement in our designs is always based on a site survey, not just an estimate from the floor plan.
5. Segmenting the network
In our office network designs, we use VLANs to separate staff, guest, CCTV and other device networks. Segmentation improves security and makes troubleshooting easier when something goes wrong.
What We Often See That Inflates Office LAN Installation Cost
The following situations come up quite often in the field, especially when our team is asked to fix or extend an existing network:
- No site survey, so cable routes and material needs only become clear halfway through the job. That is why a survey is always our first step before any quotation figures are prepared.
- Home-grade equipment used in the office, which then has to be replaced after a few months. We recommend enterprise-grade equipment, or equipment matched to the office's needs and conditions, from the start to avoid paying twice.
- No spare ports, so adding staff requires a new switch. In our designs, spare capacity is calculated from the beginning.
- Unlabeled, undocumented cabling, which makes future maintenance more expensive. Every installation we do comes with labeling and cable route documentation.
Conclusion
In our experience, an office LAN installation budget is most accurate when it starts from the number of network points, the cable routes and the WiFi requirements, all measured during a site survey. Enterprise-grade or needs-matched equipment and enough spare capacity mean the network does not have to be torn out as the office grows.
