Two engineers checking equipment in a data centre aisle, third-party maintenance savings

From the Field

Reducing Third-Party Maintenance Costs by $1.422m a Year

How competency, labour loading and vendor scope turned insourcing into a controlled operating programme at one pilot site.

Financial result

$1.422m

Net annualised maintenance savings at one pilot site. Approximately 32% of the original $4.45m annual maintenance budget at that site; not a result across the full estate.

Portfolio

~40

Data centres in the global hyperscale portfolio reviewed. The saving was delivered at one site within it, not across all forty.

Maintenance × Workforce Competency × Vendor Expenditure — the relationship that enabled the intervention.

01

The Opportunity

A global hyperscale operator maintained approximately 40 data centres and relied heavily on OEMs and specialist vendors for maintenance. Its sites also retained substantial internal technical teams because operations required continuous coverage. At a representative site, the technical workforce comprised approximately 38 technicians plus 8–9 additional site technical resources. The question was whether selected vendor-delivered activities could be performed internally without reducing required maintenance, weakening reliability or breaching operating controls.

The answer depended on more than identifying work that looked technically simple. Each activity had to be assessed against complexity, frequency, intrusiveness, competency, qualification, certification, tooling, proprietary access and regulatory requirements, then tested against the labour capacity available within the existing technical teams.

The question was whether selected vendor-delivered activities could be performed internally without reducing required maintenance, weakening reliability or breaching operating controls.

The Approach

The team carried out two connected analyses. First, it assessed technical suitability: which activities could be performed safely by internal technicians and which still required specialist or proprietary external capability. Second, it completed a labour-load assessment showing the hours required for those activities and comparing them with available internal capacity. At a representative site, the analysis indicated approximately 6,000–8,000 hours of work that could potentially be self-performed each year. This was a modelled opportunity, not a delivered saving. The analysis did not assume technicians were idle; it examined how an existing continuous-coverage workforce could absorb suitable work.

Labour-load assessment

The hours required for suitable activities, compared with available capacity within the existing technical teams.

Modelled annual opportunity

6,000–8,000 hours

Potentially self-performed each year at the representative site. A modelled opportunity, not a delivered saving.

Two connected tests established whether an activity was both technically suitable and supportable by available internal capacity.

The opportunity was then turned into a phased workforce-development programme. The competency gaps standing between the existing workforce and the suitable activities were identified, technician training and qualification pathways were developed against them, and the transfer was implemented in phases. Easier activities could move in approximately three months. Medium-complexity activities required roughly six to nine months for further training, qualifications, certification, tooling or practical preparation. Harder activities could require 12–15 months. The associated training and competency plan connected each activity with the capability needed to perform it.

Phased activity transfer

01

Easier activities

≈ 3 months

Activities could move after the initial preparation.

02

Medium complexity

6–9 months

For further training, qualifications, certification, tooling or practical preparation.

03

Harder activities

12–15 months

More complex activities required the longest development pathway.

These are the periods this programme planned for each group of activities, stated as what each could require. They are not a general implementation schedule.

Supplier economics were part of implementation. Some vendors would remove activities from scope without making a corresponding price adjustment, so the team renegotiated scope and pricing and changed suppliers where necessary. The programme retained specialist OEM/vendor activities where proprietary access, protocols, certification or technical risk made external delivery appropriate. The financial result below is the confirmed net annualised pilot outcome, not a single contract reduction.

Governance

Insourcing did not mean removing maintenance. Suitable activities transferred only after technical suitability, workforce readiness and operating controls had been assessed.

03

The Result

The pilot delivered

$1.422m

million in net annualised maintenance savings.

The original annual maintenance budget at the pilot site was $4.45 million, so the confirmed result represents approximately 32% of that pilot-site baseline. This was a delivered result at one pilot facility during its transition from construction into operations. The wider analysis identified further opportunities across the estate, but those modelled opportunities were not presented as realised portfolio savings.

How It Shaped Clarisync

The methodology emerged from operational improvement work led by professionals involved in developing Clarisync. The experience subsequently informed capabilities built into the platform.

The connected capability spans Asset Management (CMMS), Workforce & Competency and Operational Finance. Maintenance activities can be classified by complexity and competency requirements; technician qualifications can be evaluated against those requirements; and financial information can support assessment of vendor expenditure, potential savings and phased insourcing economics. Together, these capabilities support identification, workforce-readiness assessment, training-programme development, financial evaluation and implementation planning.
