IT-lokationsundersøgelser: Hvad de dækker og hvornår

An IT site survey is a physical inspection of a location before installation work begins. An engineer checks space, power, cabling, network, Wi-Fi, access and safety, then records it in a report the install team can work from. You need one before any rollout, office move, comms room build or new hardware deployment you cannot afford to get wrong.

Site surveys look like an optional extra. They are usually the cheapest part of a project — and the part that stops engineers arriving to find no power, no rack space or a locked comms room. This guide explains what a survey covers, which type you need, and what a good survey report should hand over.

What is an IT site survey?

It is a structured visit to a site, carried out before work is planned in detail. The engineer gathers facts the project team cannot see from a floor plan or an asset register.

The output is evidence: measurements, photographs, existing equipment details and a list of issues to fix before installation day. That evidence turns a guess into a plan, and a plan into an accurate quote.

A survey is different from an installation. The surveyor records and recommends. They do not normally change anything on site.

What does an IT site survey cover?

Scope depends on the project, but most surveys check the same core areas.

• Physical space: rack space, desk and wall positions, mounting points and room dimensions.
• Power: available sockets, circuits, UPS capacity and whether new supplies are needed.
• Cabling: existing structured cabling, patch panels, labelling and cable routes.
• Network: switches, ports, uplinks, firewall location and carrier line termination.
• Wi-Fi: access point positions, coverage concerns and building materials that block signal.
• Environment: cooling, ventilation, dust and moisture in comms rooms.
• Access and logistics: opening hours, parking, loading bays, lifts, security and site contacts.
• Health and safety: working at height, asbestos registers and any site-specific rules.
• Existing equipment: make, model and serial numbers of kit that will be replaced or kept.

Photographs matter as much as notes. A photo of a full patch panel or a crowded comms cupboard answers questions the install team would otherwise ask on the day.

Which type of site survey do you need?

“Site survey” covers several different jobs. Pick the one that matches the project.

Survey type	You need it when	Main output
Pre-installation survey	New hardware is going into an existing site	Readiness checklist and list of remedial work
Rollout survey	The same change is going into many sites	Standard site pack per location and a site readiness rating
Wi-Fi survey	Wireless is being designed, expanded or fixed	Access point plan and coverage heatmaps
Cabling survey	Structured cabling is being added, tidied or replaced	Cable routes, port counts and patch panel records
Comms room or data centre survey	Racks, servers or network cores are being installed or moved	Rack elevations, power and cooling assessment
Office move survey	Staff and equipment are relocating	Asset list, move plan and new-site readiness gaps

Projects often combine two or three. An office move, for example, usually needs a move survey at the old site plus cabling and Wi-Fi checks at the new one.

When do you need a site survey?

Book one whenever a failed install visit would cost more than the survey. In practice, that means:

• Before a multi-site rollout, such as new POS, network or desktop hardware.
• Before an office move, fit-out or comms room build.
• Before installing racks, servers or core network kit.
• When Wi-Fi complaints keep returning after quick fixes.
• When you take on sites through an acquisition and have no reliable records.
• When a contract requires you to support sites you have never seen.

You can usually skip a full survey for small, repeated changes at sites you already know well. Those fit better as routine IMAC work (install, move, add, change).

What should a site survey report include?

A survey is only as useful as the report. Ask for these items as standard:

1. Site details: address, contacts, access hours and any access restrictions.
2. Findings by area: space, power, cabling, network, Wi-Fi and environment.
3. Labelled photographs: comms rooms, racks, patch panels and install positions.
4. Existing asset list: make, model and serial numbers where visible.
5. Readiness status: ready, ready with minor work, or not ready.
6. Remedial actions: what must be fixed, by whom, before install day.
7. Risks and notes: safety issues, unusual layouts or dependencies on third parties.

Use the same template for every site. Consistent reports make it easy to compare sites, spot patterns and plan install waves.

How do site surveys work across many sites?

On a large estate, surveying every site can feel slow. Skipping them is slower. The usual approach is to survey a representative sample first, refine the install design, then survey the remaining sites against a fixed template.

Local engineers make this practical. Surveys can run in parallel across regions instead of one team travelling site to site. That keeps travel cost down and the project calendar short. Our guide to multi-site IT rollout planning shows where surveys fit in the overall sequence.

For data centre work, check what the facility itself allows. Some colocation sites restrict who can enter and what they can do. Our explainer on smart hands vs remote hands covers how on-site help works inside those facilities.

What are the most common site survey mistakes?

• Surveying too early. If the design changes after the visit, the survey goes out of date.
• No fixed template. Every engineer records different things, so sites cannot be compared.
• No site contact. The surveyor arrives and cannot get into the comms room.
• Ignoring remedial actions. The report flags missing power, but nobody owns the fix.
• Treating desk research as a survey. Floor plans and old records miss what has changed on site.

Throne Solutions is a B2B on-site IT field engineering provider headquartered in Sheffield, UK, supporting businesses in 60+ countries. Surveys are delivered through site surveys and installations, with the same engineers able to carry out the install that follows.

Survey work links directly to data centre support, Wi-Fi services and rollouts and migrations. For multi-country estates, it is dispatched through global field services. Send your site list and project scope, and we will come back with a survey plan and a quote.

Frequently asked questions

What is included in an IT site survey?

A typical IT site survey checks physical space, power, cabling, network equipment, Wi-Fi, environment, access and health and safety. It also records existing equipment and photographs key areas. The result is a report with a readiness status and a list of remedial actions.

When do you need a site survey before installation?

Book a survey before rollouts, office moves, comms room builds and rack or server installs. It is also worth doing when you inherit sites with no reliable records. Small, routine changes at well-known sites usually do not need one.

What is the difference between a site survey and a Wi-Fi survey?

A general IT site survey covers the whole site: space, power, cabling, network and access. A Wi-Fi survey focuses only on wireless coverage, interference and access point placement. Many projects need both.

Who should carry out an IT site survey?

A field engineer with experience of the kit being installed, ideally from the team that will do the installation. That keeps knowledge in one place and reduces handover errors.

Do you need to survey every site in a rollout?

Usually, yes, but not all at once. Survey a representative sample first, fix the design, then survey the remaining sites using a standard template. Local engineers can run surveys in parallel to keep the schedule short.
