Freelance Network Site Survey Engineer

• Please add a motivation regarding the requirements

We are looking for an experienced engineer who can independently survey, verify, and document the current network infrastructure at all in-scope sites. The initial priority is to complete the 2026 survey programme. The assignment may continue in 2027 with remediation, migration, rollout, testing, and decommissioning activities.

Assignment objective:

Create a verified current-state record for every site and identify the physical, technical, security, and operational conditions that affect migration to the new desired network. The resulting evidence must support target design, migration planning, remediation, procurement, implementation, and acceptance.

Responsibilities:

Survey preparation

Review existing site, WAN, LAN, wireless, cabling, floor-plan, circuit, and asset information before each visit.

Use a standard pre-survey data request and obtain controller, switch, CMDB, monitoring, and carrier information from the responsible suppliers.

Confirm the local contact, building access, restricted areas, escort requirements, working hours, photography rules, and safety requirements.

Prepare a site-specific visit pack and record missing information before travel.

On-site infrastructure survey

Locate and document all main equipment rooms, intermediate distribution rooms, network cabinets, demarcation points, and relevant technical spaces.

Record room ownership, physical access controls, shared access, door and rack locks, visitor arrangements, CCTV where applicable, and whether sensitive equipment is protected from unauthorised access.

Assess rack condition, available rack units, cabinet depth, door clearance, working space, equipment mounting, cable management, labelling, cleanliness, and whether racks can be closed and secured.

Document power feeds, PDUs, UPS equipment, available sockets, redundancy, grounding, cooling, temperature monitoring, fire detection or suppression, water exposure, and other environmental risks.

Verify structured cabling, patch panels, copper and fibre uplinks, cable routes, spare capacity, connector types, labelling, and visible defects.

Record carrier handoff points, routers, firewalls, SD-WAN devices, switches, wireless controllers, access points, telephony equipment, and other network-related components.

Take clear and consistently named photographs of rooms, racks, equipment, labels, patch panels, power connections, cable routes, and identified risks, subject to local security rules.

Access point and switch-port reconciliation

Create a complete access-point inventory for each site, including hostname, manufacturer, model, serial number, MAC address, asset owner, firmware, operational state, controller or cloud platform, and physical position.

Record the building, floor, room or area, mounting position, label, photo reference, and the network outlet or patch-panel reference for each access point.

Determine the connected switch, switch stack or member, switch port, PoE status, access or management VLAN, and uplink path by using approved controller exports, LLDP or CDP data, switch information, CMDB records, and supplier evidence.

Reconcile the logical supplier export with the physical survey. Flag access points that are missing, unregistered, offline, incorrectly located, duplicated, connected to an unexpected port, or present in the controller but not found on site.

Request information from the supplier when direct access is not available. Track requests, missing evidence, response dates, and escalations in the project register.

Do not disconnect equipment or change production configurations unless a separate approved change authorises the work.

Current-state and migration assessment

Confirm network ownership and identify, landlord, carrier, and shared components or services.
