🛠️ Our Survey Capabilities Include:
📦 Intrusive Survey (Openreach PIA)
We conduct detailed duct surveys to assess capacity, usability, and integrity of existing underground routes. Our surveyors rod and rope each duct section, identify blockages or collapses, and provide photographic and written evidence, ensuring that the infrastructure is suitable for new fiber under Openreach Physical Infrastructure Access (PIA) requirements.
⚡ Overhead PIA Surveys
Our overhead survey teams inspect poles and aerial routes for fiber installation, capturing data such as pole ID, structural condition, span lengths, and safety clearances. We ensure all measurements meet Openreach standards and provide complete pole audit packs with annotated photos and survey sheets.
🕳️ Confined Space Entry Surveys
Our operatives are fully confined space trained and certified to access manholes, chambers, and underground ducts where required. We ensure safe and compliant access for internal inspections, blockage tracing, and infrastructure condition assessments—especially in tight or high-risk environments.
🚧 Route Feasibility Walkouts
Comprehensive walkouts to assess proposed routes—identifying obstructions, wayleave issues, street furniture, and potential safety concerns. Each route is mapped and risk-assessed to inform optimal network design.
🗺️ GIS Data Capture & Mapping
We use high-accuracy GPS tools to produce geospatial maps and digital survey outputs, including chamber, pole, and duct locations. This supports efficient high-level and low-level design (HLD/LLD) processes.
