From our NEC4 webinar series with CECA

Make the evidence behind Defined Cost easier to review.

Gather helps site and commercial teams organise the records used in NEC4 cost reviews. Good evidence supports assessment, but it does not make every cost allowable.

The problem

Six practical review areas, not the full contractual definition.

NEC4 ECC Options C, D and E define Disallowed cost in clause 11.2(26), with ten bullet points in the standard wording. Option F has a separate definition in clause 11.2(27). The six themes below group practical checks; read the complete definition and amendments for your contract.

1
Accounts and supporting records

Connect resource, payment and allocation records to the work so the basis of the cost can be checked.

2
Payments under subcontracts and supply agreements

Check whether the payment should have been made under the relevant agreement. Evidence of payment alone does not establish allowability.

3
Procurement, early warnings and procedural requirements

Review the specific failures identified in the definition and the cost incurred only because of them. A missing early warning does not automatically disallow every cost associated with the event.

4
Defect correction

Check both correction after Completion and correction resulting from a failure to comply with a Scope constraint on how the work is provided. Defect costs before Completion are not automatically allowable.

5
Plant, Materials and resource use

Record use, wastage, availability, utilisation and any relevant instruction. Apply the allowances and exceptions in the definition rather than treating every idle resource as Disallowed cost.

6
Dispute-related costs

Distinguish the definition’s treatment of proceedings between the Parties from costs arising only because of a failure to notify the specified subcontract adjudication or tribunal proceedings. Check the actual wording.

Editorial takeaway: clear records help explain a cost. Allowability still depends on the contract.

The fix

Records that support a cost review.

Use Gather to organise site records and supporting evidence for commercial review. Keep formal notices, contractual decisions and cost assessments connected to their source records.

Category 1

Records supporting Defined Cost

Record people, equipment, materials and activity details consistently. Use references that let the commercial team connect the entry to the work and its supporting cost evidence.

Category 2

Evidence for subcontract payment reviews

Keep the relevant subcontract terms, application, assessment and supporting site records together for review. Software does not replace the judgement required to assess payment.

Category 3

Information for early warning review

Escalate matters from site promptly so the authorised team can decide what notification is required. A recorded issue or software alert is not itself a contractual early warning.

Category 4

Defect records and dates

Record when an issue was identified, what work was needed and when it was resolved. Check the contractual definition rather than relying on a date alone.

Category 5

Utilisation with an explanation

Connect allocation records with reasons for waiting, availability, redeployment and waste. Make the factual basis of the review easy to trace.

Category 6

Communications linked to the evidence

Retain the relevant notice, reply and decision alongside the supporting records. Confirm that communications have been issued through the channel required by the contract.

The webinar

Connect the webinar topic to your workflow.

A Gather walkthrough can show how site evidence is organised for commercial review. Bring an anonymised example and the questions your team needs to resolve.

In 30 minutes, we'll:

  • Take one of your live contracts (anonymised if you prefer)
  • Explore how site records support the practical review areas above
  • Show what a payment assessment looks like when both sides have the same records
  • Discuss the questions your team has about its record workflow
Frequently asked

Practical questions about Gather.

Does Gather replace our current site diary?

Gather supports site records and commercial review. Discuss which existing reports and processes you want to connect or replace during a demonstration.

Will the project manager have access to the same records?

Discuss the records each party needs and the access permissions appropriate to your project. Shared evidence can support a review without determining the contractual outcome.

Is this just for Tier 1 contractors?

The workflow can be discussed for teams of different sizes. Suitability depends on your project, contract and reporting requirements.

How long does it take to go live?

Agree the pilot scope, data preparation, training and timetable with the Gather team before rollout.

What about ISO 27001 and data ownership?

Gather’s security page lists its ISO 27001 certification. Review the current security documentation, data processing agreement and export arrangements with the Gather team before adoption.

We've already invested in a project management platform. Why add Gather?

Gather focuses on site records used in commercial review. Confirm how it will work with your existing project and contract administration tools.
