Condition data for critical structures

Bridge & Structural Inspection

Bridge and structural inspection assesses the condition of bridges and civil structures — inventory surveys, engineering inspections, materials testing and monitoring — producing the condition data asset owners use to plan maintenance. Metlab’s bridge asset management capability was strengthened in 2025 when Infrastruct, Ireland’s specialist structural condition-assessment consultancy, joined the WH Scott Group.

Overview

Ireland’s local authorities and infrastructure owners manage thousands of ageing structures with finite budgets. Reliable, consistently-recorded condition data is what turns that estate into a rankable programme of repairs rather than a list of unknowns.

Metlab combines chartered-engineer-led structural inspection with the materials testing that explains what inspectors see: cover surveys, half-cell potential, resistivity, pull-off testing, concrete cores and NDT of steelwork. Digital capture and rigorous QA carry findings from parapet to asset management system without loss.

Inspection & survey

  • Bridge inventory surveys

    Structured asset data capture for bridge management systems

  • Engineering & principal inspections

    Element-level condition rating by qualified inspection teams

  • Special & confined access inspections

    Under-bridge, boat and confined-space examination

  • Monitoring

    Crack monitoring and movement instrumentation on structures of concern

Structural materials testing

  • Reinforcement cover surveys

    Cover meter mapping of concrete elements

  • Half-cell potential & resistivity

    Corrosion risk assessment of reinforced concrete

  • Concrete cores & pull-off testing

    In-situ strength and repair-substrate verification

  • Steelwork NDT

    UT, MPI and coating inspection of structural steel

Why it matters

01

Budgets follow condition data

A defensible, consistently-scored inspection record is what unlocks and prioritises capital funding for repairs — and what protects owners when questions are asked.

02

Inspection plus testing in one team

Visual condition ratings gain force when paired with materials data. Metlab fields both disciplines together, so causes — not just symptoms — get recorded.

03

Specialist leadership

With Infrastruct as the group’s dedicated bridge and structural condition-assessment unit, programmes are led by engineers who have spent their careers on structures.

Common questions

Ask us
What is the difference between an inventory survey and an engineering inspection?

An inventory survey records what the structure is — dimensions, elements, materials, location — to populate an asset management system. An engineering inspection assesses condition, rating each element and recording defects so maintenance can be planned and prioritised.

Can you inspect structures with difficult access?

Yes — under-bridge access units, boat access, rope access through the group, confined-space-trained teams and traffic management are arranged as part of the commission.

Do you provide repair recommendations?

Inspection reports categorise defects and can extend to prioritised repair programmes with indicative costings — giving asset owners a directly actionable output rather than raw observations.
