Condition-Based Maintenance

Condition evidence helps an estate team decide which assets need attention and what that attention should involve. Agree comparable checks and a basis for intervention, so local inspection findings can inform priorities without losing the operating context or importance of each installation.

How the approach works

A scheduled attendance date does not explain whether equipment now needs adjustment, cleaning, repair or investigation. Inspection findings and measurements can support that decision where deterioration becomes detectable in time to act. The method should suit the change being assessed.

Results need context before they can be compared. A different measurement point or load can suggest a trend that does not reflect deterioration. We agree the checks, comparison method and findings that would alter the proposed maintenance action.

Consistent reporting and asset references let site observations inform priorities across a portfolio. Keep each item’s operational significance alongside its readings: similar measurements need not represent the same consequence at different buildings or on different systems.

Our full service catalogue, including every individual service, is available across every listed sector and location. For one site or several, we agree the scope, access and programme around the buildings concerned.

Who this is for

This approach is for estate teams, managing agents and commercial occupiers who need a consistent basis for assessing deterioration, recurring defects or differences between comparable installations across their properties.

03 / Maintenance

Scope and deliverables

Define assets, checks, comparison baseline, review dates and intervention criteria in the brief. The outputs identify measured or inspected condition and recommended priorities. Any physical repair or specialist investigation has its own explicit scope alongside the condition assessment.

04 / Maintenance

Typical activities

Activities may include accessible-component inspection, agreed temperature or vibration readings, comparison against a suitable baseline and review of recurring symptoms. Findings inform repair recommendations or further tests. Select the method against the asset and the form of deterioration under investigation.

How we deliver the work

We establish the assessment purpose and review service history before agreeing checks. Comparable observations are gathered and interpreted, with recommendations explaining the action proposed, when it is needed and how its result should be confirmed.

Access and preparation

Supply asset identification, earlier readings, service history and the conditions associated with faults. Agree attendance and the operating state required, including shutdown where necessary. Measurements under load and checks on stopped equipment can answer different questions.

07 / Maintenance

Responsibilities and safe working

We coordinate the assessment or task instructed and report to the nominated estate or site contact. The client establishes authority, access and operating limits. The appropriate technical resource determines the safe working method for the actual activity.

Condition evidence adds to required inspection and maintenance; a normal result does not remove an existing obligation. The HSE inspection guidance explains the relevance of risk and operating conditions to work-equipment checks.

08 / Maintenance

Priorities and response arrangements

Relate intervention criteria to the consequence of a finding. Agree the recipient of abnormal results, technical-review timing and conditions needing immediate escalation. Delivery of routine measurements is separate from any arrangement to attend an emergency.

09 / Maintenance

Asset and work records

Associate observations with the asset, place, date, method and relevant operating state. Preserve the baseline and earlier evidence, including instrument or inspection details where appropriate. Explain and record changes to review periods or thresholds rather than altering them without a traceable basis.

What affects scope and cost

Cost depends on the number of assets, access, checking method, specialist needs and review frequency. A focused investigation of one recurring fault differs from a continuing route across an estate. Define further investigation against the specific question it must resolve.

Completion and follow-up

The report identifies what was examined, the interpretation and matters still uncertain. Connect repairs to the same asset history, with subsequent checks where needed to establish the changed condition. Transfer the comparison method, baseline and actions remaining open at handover.

12 / Maintenance

Outcomes and our approach

Our aim is to turn observations into a supported maintenance choice. Findings should explain the practical next action, so the estate team receives a recommendation it can assess rather than readings with no account of their meaning.

Sectors we support

For manufacturing premises, duty and production conditions influence interpretation. In offices, condition evidence can be considered alongside occupier reports when investigating building-plant performance.

The sector directory includes retail, FM providers, managing agents, hospitality and offices; care, healthcare, veterinary and education premises; industry and logistics; residential blocks, leisure and construction; public and community buildings, critical environments, transport and utilities; social housing, laboratories and secure estates. The site’s function and users shape the service or project brief.

15 / Maintenance

Locations we cover

The recorded location directory covers towns and surrounding areas in Northumberland, Tyne and Wear, County Durham and the Tees Valley. These include Berwick-upon-Tweed, Alnwick, Morpeth, Hexham, Newcastle, Gateshead, Sunderland, Durham, Darlington, Hartlepool, Stockton-on-Tees and Middlesbrough.

For estate programmes, provide the separate address of every site so travel, attendance and the periods available for checks are considered in the arrangement.

Frequently asked questions

How is this different from predictive maintenance?

Condition-based decisions respond to evidence of the current state, such as an inspection finding or changed reading. Predictive work interprets trends to estimate future deterioration or timing. The same records may support both, but the questions differ.

Does it replace planned servicing?

No. Keep required servicing and inspections within the programme. Condition evidence may justify additional intervention or an appropriate change to suitable tasks, rather than replacing every scheduled requirement.

Do we need permanently installed sensors?

No. Portable measurements or repeat inspections may be sufficient. Consider permanent sensors only where the asset and the decision to be supported warrant continuous collection.

Can one unusual reading justify replacement?

An abnormal result may call for prompt investigation. Check its operating context, measurement basis, history and consequence before deciding that replacement is the appropriate response.

Your next step

Discuss your maintenance requirement

Provide the asset or premises list, maintenance records and operating problem you want to understand. Include useful earlier findings, possible attendance windows and the person authorised to make decisions and arrange access.
