Why compensation event backlogs are creating lost revenue on NEC projects

The issue is not lack of compensation events

Large NEC projects can generate significant volumes of compensation events throughout delivery.

Design changes, access restrictions, instructions, revised requirements, delays and changing site conditions can all create events that require commercial and programme teams to respond.

The NEC compensation event process is designed to deal with the time and cost effects of change as the project progresses.

The challenge appears when the volume becomes difficult to control.

Commercial teams can find themselves managing:

• hundreds of live compensation events,

• multiple stages of assessment,

• outstanding quotations,

• programme impacts,

• supporting evidence,

• contractual response periods,

• and large amounts of unresolved commercial value.

At this scale, compensation event management stops being a simple administrative process.

It becomes a major commercial control problem.

How compensation event volume creates revenue leakage

Every compensation event can represent potential changes to time, cost or both.

But identifying an event is only the beginning.

Teams still need to understand:

• what happened,

• when it happened,

• which activities were affected,

• what the programme impact is,

• what cost exposure exists,

• what evidence supports the event,

• and what action is required next.

When hundreds of events are moving through this process simultaneously, commercial teams are forced to continuously prioritise where they spend their time.

Lower-value events may receive less attention.

Complex events may remain unresolved for months.

Programme evidence may become harder to reconstruct.

Notifications can become disconnected from the actual delivery impact.

The result is commercial value that becomes progressively harder to recover.

Revenue is not always lost through one major commercial failure.

It can disappear gradually across hundreds of poorly controlled events.

Why NEC timescales increase the pressure

NEC compensation event management is deliberately time-sensitive.

Notifications, responses, quotations, assessments and implementation all operate through defined contractual processes.

For contractor-notified compensation events, NEC contracts can also contain time-bar provisions which may remove entitlement where events are not notified within the required period, subject to the relevant contractual exceptions and any project-specific amendments.

This makes visibility critical.

When compensation event volumes increase, teams need to understand immediately:

• which events require action,

• which events are approaching contractual deadlines,

• which quotations remain outstanding,

• which responses are overdue,

• and where potential entitlement is at risk.

Traditional spreadsheets can record this information.

The difficulty is maintaining it accurately across a live project where new events are continuously being created and existing events are constantly changing.

Why programme evidence becomes difficult to manage

Compensation events do not exist separately from project delivery.

Their impact often needs to be understood against the programme.

A commercial team may know that an instruction has been issued.

But determining its real effect can require understanding:

• affected activities,

• predecessor and successor relationships,

• available float,

• critical or near-critical paths,

• planned sequencing,

• forecast completion,

• and other concurrent changes.

This creates a major disconnect on many projects.

Commercial information sits within compensation event systems and registers.

Programme information sits within Primavera P6.

Supporting information may sit within spreadsheets, emails and reporting packs.

Teams are then expected to manually connect these environments together.

As the number of compensation events increases, this becomes increasingly difficult to sustain.

Why manual registers struggle at scale

Spreadsheets remain one of the most common methods of controlling compensation event exposure.

They work reasonably well when volumes are low.

They become much harder to manage when a project has hundreds or thousands of live commercial actions.

Teams begin spending significant amounts of time:

• updating registers,

• checking event status,

• comparing different systems,

• identifying overdue actions,

• locating programme evidence,

• preparing reporting packs,

• and manually determining which events require attention.

The register gradually becomes another reporting requirement rather than an effective commercial control system.

This creates recurring problems:

• Compensation events remaining unresolved for too long

• Weak visibility of outstanding commercial value

• Missed or approaching contractual actions

• Poor connection between programme and commercial impacts

• Difficulty prioritising the highest-value events

• Significant administrative workload

• Reduced confidence in commercial forecasting

The greater the volume becomes, the greater the risk that valuable events disappear within the backlog.

The hidden cost of unresolved compensation events

A compensation event backlog is not simply an administrative issue.

It can directly affect commercial performance.

Unresolved events can leave significant value sitting outside the agreed contract position.

Commercial teams may know that substantial potential entitlement exists while being unable to clearly establish:

• how much is recoverable,

• when it will be recovered,

• which events create the greatest exposure,

• and which events require immediate intervention.

This creates uncertainty across cash flow, forecasting and project profitability.

It also creates a compounding problem.

As time passes, the people involved move on, programme revisions accumulate and supporting evidence becomes harder to locate.

An event that may have been straightforward to demonstrate when it occurred can become significantly more difficult to substantiate months later.

How Evie helps connect compensation events with delivery data

Evie is designed to help project teams manage this problem by connecting commercial compensation event information with live programme data.

Instead of treating the compensation event register and the programme as separate environments, Evie helps teams analyse them together.

By bringing CEMAR compensation event information and Primavera P6 programme data into a connected environment, teams can gain clearer visibility across:

• compensation event status,

• outstanding commercial actions,

• programme impacts,

• affected activities,

• commercial exposure,

• and areas requiring attention.

The objective is not simply to create another compensation event register.

It is to help teams understand where commercial value is becoming exposed and where intervention should be prioritised.

Moving from administration to commercial intelligence

The biggest opportunity is changing how compensation event teams use their time.

Commercial professionals should not need to spend large parts of the working week manually reconciling registers, searching programme data and rebuilding information that already exists elsewhere on the project.

Connected commercial intelligence allows teams to focus more attention on:

• protecting entitlement,

• developing stronger assessments,

• resolving high-value events,

• improving programme evidence,

• challenging commercial exposure,

• and accelerating agreement.

This becomes increasingly important as compensation event volumes grow.

A team managing 30 events can review them manually.

A team managing hundreds or thousands requires a different operating model.

Why this matters across major NEC programmes

Large infrastructure and engineering projects are becoming increasingly data-heavy.

At the same time, commercial teams are expected to manage growing levels of change without allowing that change to undermine project performance.

This makes compensation event visibility increasingly important.

Organisations need to understand not simply how many events exist, but:

• where the value sits,

• where entitlement may be exposed,

• where programme impacts are developing,

• what requires immediate action,

• and what is preventing events from progressing.

The organisations that improve this visibility can create stronger control over both project delivery and commercial recovery.

Because managing compensation events effectively is ultimately not about maintaining a register.

It is about protecting the commercial value of the work being delivered.

Conclusion

NEC compensation events are designed to manage change as projects progress.

But on major programmes, the sheer volume of change can overwhelm traditional commercial processes.

Hundreds of compensation events, disconnected programme information, manual registers and contractual timescales create an environment where commercial value can become delayed, weakened or lost.

The solution is not simply adding more people to maintain larger spreadsheets.

It is creating better visibility across compensation events, programme impacts and commercial exposure together.

Evie helps connect these environments so teams can identify where attention is required, prioritise commercial risk and protect more of the value generated through project delivery.

Because on complex NEC projects, every unresolved compensation event can represent commercial value waiting to be recovered.
