Choose the single best next action, a–d. Every case is original and hypothetical. You act for the Contractor unless the case names another role. The stated facts and training conditions govern each answer; they are not a substitute for an executed contract.

Unless a case says otherwise, assume a project in England and the law of England and Wales; statutory payment applicability still needs its own check. NEC4 cases use the June 2017 form revised January 2023 and NEC3 cases use April 2013, unless stated otherwise. Only named Options are assumed selected. Other Options, Z clauses, incorporated documents and mandatory law could change a live answer. Numerical periods and amounts expressly supplied in cases are hypothetical training inputs. No completed CPD, examination pass or official accreditation is awarded.

No executed project contract has been supplied. The precise contractual provision has not been verified; the following is a provisional analysis pending the relevant wording. Published clause references below identify the form and the source that was checked; they do not verify an individual project’s wording.

Scoring: one point per correct answer, maximum 50. There is no official pass mark. A score does not establish competence or count automatically as completed CPD. All scenarios and numerical inputs are fictional; no actual project or party is identified.

Contract-manager actions are practical recommendations unless a specific contractual training assumption or legal requirement is identified. Published guidance is not incorporated into a contract merely by being linked. No NEC or practitioner endorsement is implied.

Questions

Name: __________________________   Date: __________________

Set 1: Contract identification, authority and notices

1. Two versions of the agreement

NEC4 ECC · June 2017 / January 2023

A substation team has an NEC4 tender PDF and a later signed agreement with different Z clauses. A supplier delay may require a notice today. The commercial assistant proposes using the tender notice template because it is familiar.

What should the contracts manager do next?

  1. Use the tender template and correct any contractual differences in the final account.
  2. Obtain the executed documents, identify the operative route and protect any imminent deadline.
  3. Use the latest NEC website amendments as the governing terms for the project.
  4. Wait until every pricing document has been reconciled before considering a notification.

My answer: a / b / c / d

2. A delivery risk before an event

NEC4 ECC · June 2017 / January 2023

A transformer supplier warns that a factory test could slip and threaten an outage. The delay has not happened and no compensation-event trigger has been identified. For this case, the checked contract requires an early warning of this risk as soon as it becomes known.

What should the contracts manager do next?

  1. Notify a compensation event stating that the Client is already liable for all delay.
  2. Record the concern internally until the supplier confirms a missed delivery date.
  3. Ask the planner to add contingency and discuss it at the final account meeting.
  4. Give the early warning now and organise mitigation with the supplier and project team.

My answer: a / b / c / d

3. Early warning already sent

NEC3 ECC · April 2013

Late Employer design information has now prevented cable-trench work. Last week you issued an early warning. The project’s checked communication rules require a separate compensation-event notification, and a notification obligation has been identified; the amount is still unknown.

What should the contracts manager do next?

  1. Prepare the separate notification through the agreed route and develop the assessment afterwards.
  2. Use the early-warning reference as proof that the compensation event was also notified.
  3. Send the cost quotation after the works finish, using it as the first notification.
  4. Ask the site engineer to add a rights-reserved line to the next daily report.

My answer: a / b / c / d

4. Uploaded but still a draft

NEC4 ECC · June 2017 / January 2023

Your NEC portal shows an urgent notice as “Draft”. The hypothetical contract says a notice is received only when submitted to the named recipient’s portal inbox. The deadline expires at 17:00 today. You are authorised to submit notices.

What should the contracts manager do next?

  1. Mark it served because the document exists on the same portal as the recipient.
  2. Email a screenshot of the draft and rely on the recipient seeing it later.
  3. Check the content and recipient, submit before 17:00 and retain the receipt record.
  4. Change the document date to yesterday and complete the submission tomorrow morning.

My answer: a / b / c / d

5. A seven-day training rule

NEC4 ECC · June 2017 / January 2023 · hypothetical amendment

For this exercise only, a bespoke notice rule gives seven calendar days after the trigger date, excludes the trigger day, includes weekends and requires receipt by 17:00 on the final day. The trigger date is 5 October 2026. No extension or exception applies.

What latest receipt deadline should the contracts manager record?

  1. 11 October 2026 at 17:00, counting the trigger date as the first day.
  2. 12 October 2026 at 17:00, with service arranged and evidenced before then.
  3. 14 October 2026 at 17:00, counting only ordinary Monday-to-Friday days.
  4. 12 October 2026 at 23:59, allowing the full final calendar day for service.

My answer: a / b / c / d

6. Possible time bar, incomplete records

NEC4 ECC · June 2017 / January 2023

An outage was withdrawn several weeks ago. Your team disagrees about when it became aware, and the executed Z clause has not yet been retrieved. The director wants to wait for the disruption report before taking any contractual action.

What should the contracts manager do next?

  1. Use an eight-week period from memory and tell the director entitlement is secure.
  2. Abandon the event because uncertainty about the date means it must be time-barred.
  3. Complete the disruption report first so the first notice contains the final amount.
  4. Escalate urgently, retrieve the wording and chronology, and arrange a reviewed protective notice.

My answer: a / b / c / d

7. The TWC requests more steel

NEC4 ECC · June 2017 / January 2023

The principal contractor’s TWC asks your steelwork team to add bracing. Immediate stability is already controlled. The checked authority matrix gives this TWC no power to instruct a contractual change, and the extra bracing’s scope status is disputed.

What should the contracts manager do next?

  1. Maintain the safety controls and seek a decision from the authorised contract administrator.
  2. Treat the TWC’s technical request as a priced change because the TWC controls temporary works.
  3. Reject the technical concern until the Project Manager accepts the additional cost.
  4. Agree a final price with the site foreman and describe it as a Project Manager instruction.

My answer: a / b / c / d

8. Conflicting scope documents

NEC3 ECC · April 2013

For an excavation package, the Works Information drawing shows one access arrangement and an incorporated specification describes another. The executed agreement’s precedence provisions have not been checked. The difference affects temporary access and price.

What should the contracts manager do next?

  1. Use the drawing because drawings always take precedence over written specifications.
  2. Use the cheaper arrangement and ask for approval only after construction has begun.
  3. Identify the inconsistency, check the agreed precedence and seek the required clarification.
  4. Split the difference between the two arrangements and include half the cost in the next application.

My answer: a / b / c / d

9. A risk meeting with no decisions

NEC4 ECC · June 2017 / January 2023

An early-warning meeting discusses a crane access restriction. The minutes list concerns but assign no actions. A possible compensation event is being considered separately. The contracts manager needs to improve the outcome of the meeting.

What should the contracts manager do next?

  1. Close the warning because all parties have now been made aware of the problem.
  2. Issue minutes allocating the entire cost to the Client without seeking a contractual decision.
  3. Leave the minutes unchanged to avoid creating evidence that mitigation was possible.
  4. Agree feasible actions, owners and dates, and keep the separate notice process under review.

My answer: a / b / c / d

10. NEC3 administration on an NEC4 template

NEC3 ECC · April 2013

An overhead-line project uses NEC3 ECC. A new contracts manager proposes replacing the existing Risk Register and risk-reduction meeting process with an NEC4 template, including a programme deemed-acceptance procedure, without checking the signed agreement.

What should the contracts manager do next?

  1. Keep the actual NEC3 process and verify each proposed change against the executed contract.
  2. Apply the complete NEC4 procedure because the newer edition supersedes NEC3 automatically.
  3. Change only the document titles and assume all underlying steps are identical.
  4. Stop using a risk register until both parties sign a new NEC4 contract.

My answer: a / b / c / d

Set 2: Temporary works: responsibility and safe decisions

11. Movement in a propped structure

NEC4 ECC · June 2017 / January 2023

During a commercial refurbishment, the site supervisor reports unexpected movement beside temporary props. A compensation-event quotation for additional support is awaiting assessment. Workers remain in the affected area, and the designer has not assessed the movement.

What should the contracts manager do next?

  1. Obtain agreement to the extra support price before asking the team to stop work.
  2. Continue under the existing permit because the original design was checked.
  3. Get the site team to stop affected work, secure the area and obtain competent engineering review.
  4. Send a compensation-event reminder and make the Project Manager responsible for deciding whether work is safe.

My answer: a / b / c / d

12. Equipment design or design of the works?

NEC4 ECC · June 2017 / January 2023

A removable excavation support system has been confirmed as the Contractor’s Equipment. The Project Manager requests design particulars. The planner assumes that the clause 21.2 hold on relevant work applies automatically. The actual Scope may contain additional hold points, and safety checks remain essential.

What should the contracts manager do next?

  1. Check clause 23.1 and the actual hold points, supply required particulars and retain the safety controls.
  2. Apply clause 21.2 automatically because all temporary works are contractor-designed works.
  3. Refuse the submission because Equipment designs can never be requested by the Project Manager.
  4. Proceed immediately because Equipment is outside every contractual and statutory safety restriction.

My answer: a / b / c / d

13. Starting before required design acceptance

NEC4 ECC · June 2017 / January 2023

A retaining structure is part of the works, and the Contractor must design it. The checked Scope requires its design particulars to be accepted before the relevant work starts, consistent with the applicable clause 21.2. The submission is outstanding, but the concrete slot is booked tomorrow.

What should the contracts manager do next?

  1. Start the concrete work because booking the pour gives the Contractor a programme priority.
  2. Hold the relevant work, expedite a compliant submission and assess the resulting programme exposure.
  3. Replace contractual acceptance with the checker’s certificate and proceed with the pour.
  4. Treat the lack of a rejection email as acceptance and record the work as authorised.

My answer: a / b / c / d

14. Acceptance blamed for a design error

NEC3 ECC · April 2013

The Project Manager accepted the Contractor’s submitted design for a wall. A later check identifies a design error. A colleague proposes rejecting responsibility solely because the Project Manager accepted the design. No amendment transferring that responsibility has been identified.

What should the contracts manager do next?

  1. Transfer the entire design correction cost to the Employer solely on the basis of acceptance.
  2. Delete the original design files and replace them with the corrected revision.
  3. Ask the checker to describe the error as a new instruction to secure a compensation event.
  4. Contain the consequences, investigate responsibility and preserve the design and acceptance history.

My answer: a / b / c / d

15. A heavier crane on the working platform

NEC4 ECC · June 2017 / January 2023

The Contractor substitutes a heavier crane for a substation lift. The working-platform design was checked for the original crane only; revised load data have not been supplied. The lift plan is otherwise ready, and no Client instruction required the substitution.

What should the contracts manager do next?

  1. Use the platform because the existing design certificate has not expired.
  2. Raise a compensation event and allow the lift while the additional platform cost is assessed.
  3. Hold the affected lift and obtain revised loading, design and checks before assessing cost responsibility.
  4. Ask the crane supplier to confirm that any ground failure will be its financial responsibility.

My answer: a / b / c / d

16. Bracing omitted from permanent-works drawings

NEC4 ECC · June 2017 / January 2023

A data-centre frame needs temporary erection bracing that is not shown on the permanent-works drawings. The executed Scope expressly requires the Contractor to design and provide erection stability. No change to that obligation has yet been identified.

What should the contracts manager do next?

  1. Arrange the required stability design and review other event evidence before asserting additional entitlement.
  2. Notify the full bracing cost as automatically recoverable because it is absent from the drawings.
  3. Require the permanent-works designer to supply every temporary member free of charge.
  4. Proceed without the bracing until the Project Manager changes the permanent-works drawings.

My answer: a / b / c / d

17. A changed scaffold interface

NEC4 ECC · June 2017 / January 2023

A scaffold tie arrangement was checked against one façade revision. Site teams now propose different tie locations to clear services. The project procedure requires changes affecting the design to be reviewed before use. The earlier check certificate has not been withdrawn.

What should the contracts manager do next?

  1. Rely on the existing certificate because the scaffold still uses the same proprietary components.
  2. Let the installer agree the revised positions verbally and update the drawing after use.
  3. Accept the revised positions if the commercial manager signs the additional cost sheet.
  4. Control use of the affected scaffold and obtain a documented review of the revised arrangement.

My answer: a / b / c / d

18. Design appointment or site inspection?

NEC4 PSC · June 2017 / January 2023

You manage a temporary-works consultant’s appointment. Its Scope provides for a design and an independent check, but expressly excludes installation inspection. The contractor asks your designer to sign that the propping was installed correctly. No inspection has been carried out.

What should the contracts manager do next?

  1. Sign the installation confirmation because the consultant designed the propping.
  2. Explain the scope limit and arrange a competent inspection through an authorised appointment or change.
  3. Ask the checker to sign the installation confirmation using the design check alone.
  4. Sign subject to a general disclaimer that nobody should rely on the document.

My answer: a / b / c / d

19. A non-designer changes the propping layout

Great Britain · CDM 2015 / NEC appointment to be checked

A commercial employee revises a propping layout to reduce hire cost and issues it for construction. They have no demonstrated competence for this design task. The project team says CDM designer duties cannot apply because their job title is “contracts manager”.

What should the contracts manager do next?

  1. Withdraw the unreviewed change from use and arrange competent design review and risk communication.
  2. Allow the change because only people employed with the title “designer” have design duties.
  3. Ask the employee to add “commercial suggestion” to the issued drawing and continue work.
  4. Transfer responsibility to the installer by getting a signed acknowledgement of receipt.

My answer: a / b / c / d

20. Removing props to return hire equipment

NEC4 ECC · June 2017 / January 2023

A reinforced-concrete transfer slab remains supported by props. The hire period ends tomorrow. The designer’s removal sequence requires verified strength and an authorised release, neither of which is available. The supplier is pressing for collection.

What should the contracts manager do next?

  1. Remove alternate props to reduce hire cost while waiting for the strength records.
  2. Treat the hire expiry date as permission to dismantle the temporary support.
  3. Keep support in place and obtain the strength evidence and authorised removal sequence before release.
  4. Ask the Project Manager to approve the collection invoice instead of obtaining a release.

My answer: a / b / c / d

Set 3: Programmes, change and compensation events

21. An activity finished late

NEC4 ECC · June 2017 / January 2023

Transformer plinth construction finishes four working days later than planned. The site report says “claim four days to Completion”. You have not checked the Accepted Programme, remaining float, delivery logic or whether planned Completion has moved.

What should the contracts manager do next?

  1. Claim four days because the plinth activity finished four days late.
  2. Ask the planner to analyse the event against the relevant programme, logic, progress and float.
  3. Claim no time because the transformer has not yet arrived on site.
  4. Divide the delay equally between the Contractor and Client without a programme analysis.

My answer: a / b / c / d

22. The programme omits design release

NEC4 ECC · June 2017 / January 2023

The submitted programme shows a crane lift and platform construction but omits design, checking and permit-to-use activities. The case’s checked Scope requires these steps before loading. The construction team says programme bars should show site work only.

What should the contracts manager do next?

  1. Leave the programme unchanged and record the design steps in the commercial risk allowance.
  2. Remove the hold points from the procedure because they are missing from the programme.
  3. Add all design activities on the lift date so the advertised finish date stays unchanged.
  4. Incorporate the required design, check and release activities with realistic dependencies and dates.

My answer: a / b / c / d

23. Forecast date or contractual date?

NEC4 ECC · June 2017 / January 2023

The Contract Data shows a Completion Date of 30 November. The current programme forecasts planned Completion on 20 November. A new forecast shows 25 November. No compensation event changing the Completion Date has been implemented and no other date change is agreed.

What should the contracts manager do next?

  1. Keep the contractual date at 30 November and investigate the five-day forecast movement.
  2. Replace the contractual Completion Date with 25 November because the latest forecast controls it.
  3. Record an automatic five-day extension to 5 December without analysing the cause.
  4. Ignore the movement because a forecast before 30 November can never create commercial consequences.

My answer: a / b / c / d

24. Contractor delay before the event

NEC4 ECC · June 2017 / January 2023

At the applicable dividing date, an earlier Contractor resource shortage has already delayed the works. A separate notified compensation event will affect the same sequence. The planner proposes assessing the new event on an unprogressed tender programme.

What should the contracts manager do next?

  1. Include all earlier Contractor delay in the new event so the revised programme matches the site position.
  2. Exclude the new event because Contractor delay automatically removes all possible time entitlement.
  3. Use the relevant Accepted Programme, account for the position at the dividing date, then model the event.
  4. Choose whichever programme produces the largest extension, then negotiate downwards.

My answer: a / b / c / d

25. No programme reply yet

NEC4 ECC · June 2017 / January 2023

The Project Manager has not replied to a programme submission. For this case, the checked contract requires a further failure notification and an additional response period before its deemed-acceptance mechanism can operate. Neither step has occurred.

What should the contracts manager do next?

  1. Mark the programme accepted because the first response deadline has passed.
  2. Follow the verified failure-notification process, calculate the further period and retain service evidence.
  3. Re-label the programme as a compensation-event quotation to create acceptance.
  4. Delete the submission and use the tender programme indefinitely.

My answer: a / b / c / d

26. An instructed platform enlargement

NEC4 ECC · June 2017 / January 2023 · Option A

The Project Manager formally changes the Client’s Scope to enlarge a working platform for an additional delivery area. For this case, it is agreed to be a compensation event and quotations have been instructed. The team proposes waiting until all invoices arrive before assessing it.

What should the contracts manager do next?

  1. Price only the completed invoices because Option A compensation events cannot use forecasts.
  2. Reuse the original activity price without considering the change in work or time.
  3. Continue the work and leave both the quotation and programme effect to final account.
  4. Establish the assessment basis, forecast the change’s cost and programme effect, and meet the quotation process.

My answer: a / b / c / d

27. Unexpected material in an excavation

NEC4 ECC · June 2017 / January 2023

An excavation at a utility site exposes buried concrete that was not shown on one drawing. Other Site Information and tender inspection records have not been reviewed. Work in the affected area has been made safe. The site team wants to claim the entire excavation overrun immediately.

What should the contracts manager do next?

  1. Assume entitlement because any item missing from a drawing is an unforeseeable physical condition.
  2. Reject the event because the Contractor always carries every ground-condition risk under NEC.
  3. Preserve the discovery evidence, review the actual physical-conditions test and protect any required notification.
  4. Remove the concrete before recording it so excavation output is restored quickly.

My answer: a / b / c / d

28. Rainfall at the wrong weather station

NEC4 ECC · June 2017 / January 2023 · hypothetical weather provision

A site diary records persistent rain and lost working time. The case’s checked weather provision requires a specified measurement to exceed a contractual threshold using a named station. The team has supplied only a regional news report and a different station’s totals.

What should the contracts manager do next?

  1. Obtain the specified station’s measurement, apply the agreed threshold and separately assess impact and notice duties.
  2. Claim every wet day because lost production alone satisfies the stated weather threshold.
  3. Use the highest regional reading because any nearby station is contractually interchangeable.
  4. Abandon the enquiry because weather events can never affect NEC contract entitlement.

My answer: a / b / c / d

29. Float in a simple training network

NEC4 ECC · June 2017 / January 2023

In this hypothetical programme model, a notified event adds four working days to an activity. That activity has exactly two working days of free float before its sole successor; the successor is on the critical path to planned Completion. Calendars are identical, no other logic changes and no further float exists.

What programme movement should the contracts manager demonstrate?

  1. Four working days later, without allowing for the two days of available free float.
  2. No movement, because any activity with float is immune from causing completion delay.
  3. Six working days later, adding the original float to the event’s four days.
  4. Two working days later in this model, supported by the logic and a separate contractual assessment.

My answer: a / b / c / d

30. A quotation deadline cannot be met

NEC4 ECC · June 2017 / January 2023

The compensation-event quotation is due tomorrow under the checked project timetable. A specialist’s necessary design input is late. The applicable procedure permits an agreed extension, but none has been agreed. You expect the completed quotation to take another week.

What should the contracts manager do next?

  1. Change the due date in your tracker to next week without telling the Project Manager.
  2. Request an authorised extension promptly, explain the missing input and manage the original deadline until agreed.
  3. Send a blank quotation and describe it as complete to stop the time period running.
  4. Wait for the specialist and explain the delay only after the new quotation is ready.

My answer: a / b / c / d

Set 4: Money, payment and commercial evidence

31. Assessing the effect, not the whole new price

NEC4 ECC · June 2017 / January 2023 · Option A

For an agreed compensation event, the hypothetical forecast Defined Cost of the original support arrangement is £18,000 and of the instructed replacement is £26,000. The Fee is 8%. All work is after the applicable dividing date; no other costs or time effects arise and no alternative valuation is agreed.

What increase should the contracts manager include in the quotation?

  1. £28,080, being the full replacement cost plus 8% Fee.
  2. £8,000, being the replacement cost less the original forecast cost.
  3. £8,640, being the £8,000 cost difference plus £640 Fee.
  4. £26,000, being the replacement supplier’s total forecast price.

My answer: a / b / c / d

32. A transparent quotation total

NEC4 ECC · June 2017 / January 2023 · hypothetical eligible cost inputs

All of the following are agreed eligible incremental Defined Cost for this training calculation: 36 labour hours at £48/hour, four plant days at £135/day and £420 materials. There are no deductions or other allowances. Apply a Fee of 8% to the whole eligible subtotal; exclude VAT.

What amount should the contracts manager submit?

  1. £2,903.04, with the labour, plant, materials and Fee shown separately.
  2. £2,688.00, treating the eligible cost subtotal as the final quotation amount.
  3. £2,869.44, applying Fee to labour and plant but excluding the materials.
  4. £3,483.65, adding a further 20% to the cost-plus-Fee total.

My answer: a / b / c / d

33. An invoice is not the whole entitlement case

NEC4 ECC · June 2017 / January 2023 · Option C

A subcontractor submits a £14,000 invoice labelled “extra platform works”. It combines original work, a Contractor method change and a potential Client-instructed change. The relevant cost rules and records have not been applied. The accounts team proposes adding the whole invoice to the Client assessment.

What should the contracts manager do next?

  1. Pass the entire invoice through because every paid subcontract invoice is Defined Cost.
  2. Reject every item because subcontractor costs are excluded from all NEC assessments.
  3. Apply the same percentage reduction to each item without checking its cause or scope.
  4. Separate the items and test each against scope, causation, cost rules and supporting records.

My answer: a / b / c / d

34. A target overrun forecast

NEC4 ECC · June 2017 / January 2023 · Option C

A project forecast is now £100,000 above its current target. The director says the whole excess must be a Contractor loss and instructs the team to stop investigating potential compensation events. Final cost and the sharing calculation have not been assessed.

What should the contracts manager do next?

  1. Accept the whole forecast excess as an immediate final deduction from the Contractor.
  2. Review cost eligibility, potential target changes and the actual share mechanism while reducing avoidable cost.
  3. Raise the target by £100,000 because every forecast overrun automatically changes the target.
  4. Stop recording the overrun until the final account to avoid showing an adverse trend.

My answer: a / b / c / d

35. Actual cost differs from an implemented forecast

NEC4 ECC · June 2017 / January 2023

An implemented compensation-event assessment included forecast crane standby. Actual standby later costs less. For this exercise, the checked contract prohibits revising that assessment solely because the forecast proves wrong; no correction of a stated assumption or other permitted basis has been identified.

What should the contracts manager do next?

  1. Retain the implemented assessment and investigate separately if a genuine permitted basis for change emerges.
  2. Reopen it automatically and substitute the actual standby invoices for the implemented forecast.
  3. Apply the prohibition only when actual cost is lower, while claiming more whenever it is higher.
  4. Create a new event describing the same forecast difference without any new contractual trigger.

My answer: a / b / c / d

36. A valid notified sum is disputed

NEC works subcontract · England · HGCRA applies

You manage the payer’s subcontract. Legal review has confirmed a valid £80,000 notified sum, that section 111 applies and that no relevant exception or valid pay-less notice exists. The final date for payment is tomorrow. Your valuation is £63,000 and remains disputed.

What should the contracts manager do next?

  1. Pay £63,000 and treat the internal valuation spreadsheet as the missing pay-less notice.
  2. Withhold the full amount until both parties agree the correct final valuation.
  3. Arrange payment of £80,000 by the final date and obtain advice on pursuing the valuation dispute separately.
  4. Backdate a pay-less notice to the last permitted service date and pay the lower amount.

My answer: a / b / c / d

37. A pay-less notice that gives no amount

NEC works subcontract · England · HGCRA applies

The payer can still serve a pay-less notice within the verified time limit. The draft merely says “your application is excessive and disputed”. It gives no sum considered due or calculation basis. You are checking the draft before authorised issue.

What should the contracts manager do next?

  1. Issue it unchanged because the word “disputed” is enough to identify a lower payment.
  2. Attach a blank spreadsheet and fill in the amount after the notice deadline.
  3. Send it only to the site supervisor because they already know the valuation dispute.
  4. State the sum and calculation basis, check authority and recipient, and serve through the valid route in time.

My answer: a / b / c / d

38. A mixed package at a nuclear facility

NEC contract · England · mixed activities

One package includes ordinary building foundations, installation of process plant and steelwork supporting that plant at a nuclear-processing site. A colleague says the whole contract is outside construction-payment legislation simply because of the site’s name.

What should the contracts manager do next?

  1. Map the actual operations against sections 104–105 and obtain specialist advice on the mixed package.
  2. Treat every activity as excluded because all work at any nuclear site is exempt.
  3. Treat every activity as included because the parties selected an NEC form.
  4. Use the contractor’s invoice headings as the sole test of statutory applicability.

My answer: a / b / c / d

39. Stopping for non-payment tomorrow

NEC contract · England · HGCRA section 112 assumed applicable

A confirmed notified sum remains unpaid after the final date. The section 112 payment precondition is met, but no notice of intention to suspend has been served and no separate contractual right is relied on. The director wants everyone off site tomorrow. Temporary support will still need care.

What should the contracts manager do next?

  1. Demobilise tomorrow because passing the final date removes every further notice requirement.
  2. Obtain urgent review, arrange a compliant notice and plan any lawful suspension around continuing safety needs.
  3. Terminate the contract immediately because any late payment is an automatic termination event.
  4. Remove the props first to ensure the payer cannot benefit from unpaid temporary works.

My answer: a / b / c / d

40. Two events, one labour return

NEC4 ECC · June 2017 / January 2023

The same weekly labour sheet supports a claim for late permanent-works information and a separate access restriction. Both proposed quotations include all 160 hours. The sheet contains no activity, location or event allocation, and unaffected work also occurred.

What should the contracts manager do next?

  1. Use all 160 hours in both quotations because the events happened during the same week.
  2. Allocate 80 hours to each event automatically because there are two causes.
  3. Reconstruct a supported allocation from contemporaneous records and disclose any unresolved overlap.
  4. Discard the original sheet and ask the supervisor to sign two replacement historic records.

My answer: a / b / c / d

Set 5: Contract interfaces, close-out and disputes

41. A subcontract notice sent to the main-contract PM

NEC4 ECS · June 2017 / January 2023

You manage a piling Subcontractor. Its checked ECS requires event notifications to the Contractor through the subcontract portal. Your engineer sent a notice only to the main-contract Project Manager, who is not the specified ECS recipient. A relevant notification deadline has not yet expired.

What should the contracts manager do next?

  1. Rely on the email because the Project Manager is senior to the Contractor’s commercial team.
  2. Arrange a compliant subcontract notification immediately and retain evidence of receipt by the Contractor.
  3. Wait until the main-contract event is accepted before notifying under the subcontract.
  4. Copy the Project Manager’s name into the subcontract records as if they were the Contractor.

My answer: a / b / c / d

42. A consultant receives an ECC notice template

NEC3 PSC · April 2013

You manage a design consultant under NEC3 PSC. Additional temporary-works design is requested after late permanent-works information. The contractor sends an ECC compensation-event template and says the same clauses and periods automatically govern your appointment. Your PSC Scope and amendments have not been checked.

What should the contracts manager do next?

  1. Use the ECC clauses because all contracts in the NEC3 family have identical mechanisms.
  2. Treat the extra design as free because PSC appointments cannot contain change mechanisms.
  3. Replace the PSC Scope with Works Information to make the ECC template fit.
  4. Check the PSC Scope, authority, change and notice provisions, then adapt the communication to that appointment.

My answer: a / b / c / d

43. A maintenance task becomes an excavation

NEC3 TSSC · April 2013

A term-service crew attending a pump fault discovers that repair may need an excavation beside live services. The proposed Task Order is still a draft and the Service Information for the existing task does not establish this excavation’s scope or controls. The area is safe and isolated.

What should the contracts manager do next?

  1. Establish the authorised task and responsibilities, arrange competent planning and follow this contract’s own process.
  2. Start excavation because every draft Task Order automatically authorises any related work.
  3. Use the ECC Accepted Programme as the sole authority to change the term-service task.
  4. Treat the work as a supply-only order so temporary-works management duties do not arise.

My answer: a / b / c / d

44. Who supplies the crane and offloading platform?

NEC4 SC · June 2017 / January 2023

You manage the purchaser’s transformer supply contract. Delivery is booked, but the documents reviewed so far do not establish responsibility for offloading, cranage, ground support or temporary stability. The supplier says delivery to site includes all of these tasks; the works contractor disagrees.

What should the contracts manager do next?

  1. Assume the Supplier owes every site activity because the contract is called a Supply Contract.
  2. Let the driver and crane operator allocate responsibility when the transformer arrives.
  3. Resolve the goods/services and works interfaces from both contracts and agree a competent offloading plan before release.
  4. Assume the works contractor is responsible for all offloading costs because it controls site access.

My answer: a / b / c / d

45. Assuming a new short-form design limitation

NEC4 ECSC · agreement entered in 2022; revisions unconfirmed

A contractor facing a temporary-works design claim finds NEC’s January 2023 short-form design-liability amendment. It assumes the amendment automatically protects its 2022 agreement. Neither incorporation of the amendment nor the relevant Contract Data selection has been established.

What should the contracts manager do next?

  1. Apply the 2023 limitation automatically because it is newer than the signed agreement.
  2. Check incorporation, the Contract Data design-standard selection and the actual insurance/appointment position.
  3. Insert the wording into the project copy and describe it as the original executed condition.
  4. Use NEC4 ECC Option X15 as if it were automatically included in every short contract.

My answer: a / b / c / d

46. Use of one section is not the whole close-out

NEC3 ECC · April 2013 · Option X5

The Employer begins using one completed section of a utilities project. Other sections still require work. The team wants to mark the whole contract complete and release all retention simply because the Employer has started using the first section.

What should the contracts manager do next?

  1. Record whole-contract Completion immediately because use of any part means all work is complete.
  2. Release all retention automatically because X5 removes the need to check any retention terms.
  3. Refuse to record the section’s status until all sections reach Completion.
  4. Check sectional Completion, take-over and payment provisions and obtain the appropriate separate records.

My answer: a / b / c / d

47. An informal agreement to leave a Defect

NEC4 ECC · June 2017 / January 2023

A non-safety-critical concrete finish does not comply with the Scope. The Client’s site representative says it can remain, but lacks the authority to alter the Scope. For this case, the checked contract permits an authorised proposal and agreement to accept the Defect; that process has not occurred.

What should the contracts manager do next?

  1. Delete the Defect from the register because the Client’s representative is content with the appearance.
  2. Use the formal process to seek an authorised agreement and record the resulting scope and commercial position.
  3. Invoice the Client for leaving the Defect because doing less work is always a compensation event.
  4. Treat the representative’s comment as a blanket waiver of every outstanding quality obligation.

My answer: a / b / c / d

48. Mixing a notice with a settlement offer

NEC4 ECC · June 2017 / January 2023

A manager drafts one email combining an imminent contractual event notification with an offer to accept half the disputed value in final settlement. The draft is marked “without prejudice” and has not been approved or sent. The notice must remain clearly identifiable through the verified notice route.

What should the contracts manager do next?

  1. Separate the formal notice from the proposed settlement and obtain the necessary legal and commercial review.
  2. Send the combined email because the label guarantees that it is both a valid notice and legally privileged.
  3. Delete the notice and rely on the settlement proposal to reserve every contractual right.
  4. Remove the label and accept half the value immediately without checking settlement authority.

My answer: a / b / c / d

49. An adjudication notice arrives

NEC agreement · dispute Option and jurisdiction not yet confirmed

An adjudication notice alleging a £450,000 temporary-works design loss arrives this morning. A manager proposes deleting earlier design drafts and waiting for the next commercial meeting. The dispute Option, appointment route and applicable procedural timetable have not been established.

What should the contracts manager do next?

  1. Wait for the commercial meeting because a notice alone cannot create any urgent procedural work.
  2. Delete the superseded designs because only the latest drawing can be relevant evidence.
  3. Escalate immediately, preserve the complete evidence set and establish jurisdiction, procedure and deadlines.
  4. Assume a familiar deadline from another NEC project and promise the same response timetable.

My answer: a / b / c / d

50. Original stability duty plus an instructed change

NEC4 ECC · June 2017 / January 2023

On a data-centre project, the Contractor already owes erection stability. The Project Manager now instructs a changed sequence for a generator delivery, potentially adding bracing and affecting an outage. Existing safety controls remain effective, but the changed sequence is not yet checked and a separately identified notice deadline expires today.

What should the contracts manager do next?

  1. Claim every bracing cost as additional and start the changed sequence to avoid the outage being missed.
  2. Reject all additional entitlement because the original Scope mentioned temporary stability.
  3. Wait for the final structural design and complete cost report before sending any contractual communication.
  4. Protect today’s notice, hold the unchecked sequence and separate original duties from evidenced change effects.

My answer: a / b / c / d

Best next action: Map the actual operations against sections 104–105 and obtain specialist advice on the mixed package.

Reasoning and source basis: Legal requirements: HGCRA 1996 sections 104(5) and 105, including 105(2)(c). This identifies the need for analysis; it does not classify every nuclear or energy package.

Evidence to secure: Actual work descriptions, site primary activity, contract scope split and specialist statutory analysis.

Reflection: What actual contract wording or evidence would you check before taking this action on your own project?

39. Stopping for non-payment tomorrow — answer b

NEC contract · England · HGCRA section 112 assumed applicable

Best next action: Obtain urgent review, arrange a compliant notice and plan any lawful suspension around continuing safety needs.

Reasoning and source basis: Legal requirement: HGCRA 1996 section 112(1)–(3), including at least seven days’ notice stating the grounds. This statutory period is not a generic NEC event-notification period.

Evidence to secure: Payment default, reviewed notice/receipt, expiry calculation, suspension scope and temporary-works care plan.

Reflection: What actual contract wording or evidence would you check before taking this action on your own project?

40. Two events, one labour return — answer c

NEC4 ECC · June 2017 / January 2023

Best next action: Reconstruct a supported allocation from contemporaneous records and disclose any unresolved overlap.

Reasoning and source basis: Practical evidence and causation control. SCL is guidance on records and analysis; it does not supply a contractual entitlement or a universal disruption formula.

Evidence to secure: Original timesheets, diaries, task/location data, programme records and a transparent reconciliation.

References: Delay and Disruption Protocol

Reflection: What actual contract wording or evidence would you check before taking this action on your own project?

41. A subcontract notice sent to the main-contract PM — answer b

NEC4 ECS · June 2017 / January 2023

Best next action: Arrange a compliant subcontract notification immediately and retain evidence of receipt by the Contractor.

Reasoning and source basis: Hypothetical verified ECS notice rule; the NEC4 ECS publisher description supports the separate subcontract context. ECC recipient, deadlines and outcomes are not imported.

Evidence to secure: Executed ECS route, event/awareness dates, notice, Contractor recipient and portal receipt.

References: NEC4 Engineering and Construction Subcontract

Reflection: What actual contract wording or evidence would you check before taking this action on your own project?

42. A consultant receives an ECC notice template — answer d

NEC3 PSC · April 2013

Best next action: Check the PSC Scope, authority, change and notice provisions, then adapt the communication to that appointment.

Reasoning and source basis: Practical NEC3 PSC contract check. NEC’s 2016 deliverables article discusses PSC Scope; it is not evidence that ECC notice clauses apply.

Evidence to secure: PSC agreement, Scope/deliverables, amendments, request authority and service/change chronology.

References: Submission of deliverables under the PSC · NEC3 April 2013 complete family

Reflection: What actual contract wording or evidence would you check before taking this action on your own project?

43. A maintenance task becomes an excavation — answer a

NEC3 TSSC · April 2013

Best next action: Establish the authorised task and responsibilities, arrange competent planning and follow this contract’s own process.

Reasoning and source basis: Practical recommendation. NEC3 TSSC catalogue identifies Service Information, Price List and Task Order; it does not verify the operative wording for this hypothetical task.

Evidence to secure: Service Information, authorised task, services information, excavation/TW plan and communication route.

References: NEC3 Term Service Short Contract · Temporary works FAQs

Reflection: What actual contract wording or evidence would you check before taking this action on your own project?

44. Who supplies the crane and offloading platform? — answer c

NEC4 SC · June 2017 / January 2023

Best next action: Resolve the goods/services and works interfaces from both contracts and agree a competent offloading plan before release.

Reasoning and source basis: Practical interface review supported by the NEC4 SC catalogue. Check actual Scope, delivery terms and any incorporated Incoterms; no particular delivery term is assumed.

Evidence to secure: Supply and works scopes, delivery terms, lifting plan, loads/ground support and interface responsibility matrix.

References: NEC4 Supply Contract

Reflection: What actual contract wording or evidence would you check before taking this action on your own project?

45. Assuming a new short-form design limitation — answer b

NEC4 ECSC · agreement entered in 2022; revisions unconfirmed

Best next action: Check incorporation, the Contract Data design-standard selection and the actual insurance/appointment position.

Reasoning and source basis: Official NEC4 January 2023 amendment PDF: ECSC Contract Data and clause 83.4, pp.26–27; ECSS counterpart pp.29–30. Its conditional operation is not retrospective incorporation.

Evidence to secure: Executed ECSC, agreed amendments, relevant Data selection, design standard and insurance wording.

References: NEC4 January 2023 Contract Amends · NEC4 2023 amendments now available

Reflection: What actual contract wording or evidence would you check before taking this action on your own project?

46. Use of one section is not the whole close-out — answer d

NEC3 ECC · April 2013 · Option X5

Best next action: Check sectional Completion, take-over and payment provisions and obtain the appropriate separate records.

Reasoning and source basis: NEC’s NEC3 ECC FAQ distinguishes Completion from take over and discusses X5. No retention percentage or release date is inferred without the applicable X16 or bespoke wording.

Evidence to secure: Section definitions, Works Information completion requirements, certificates, use dates and retention terms.

References: Completion, take over and retention of sections

Reflection: What actual contract wording or evidence would you check before taking this action on your own project?

47. An informal agreement to leave a Defect — answer b

NEC4 ECC · June 2017 / January 2023

Best next action: Use the formal process to seek an authorised agreement and record the resulting scope and commercial position.

Reasoning and source basis: Hypothetical acceptance process supplied in the case; actual NEC4 Defect, Scope-change and valuation provisions must be checked. Safety and applicable law cannot be waived by this learning scenario.

Evidence to secure: Defect record, Scope requirement, authority, formal proposal and authorised agreement.

References: NEC4 Engineering and Construction Contract

Reflection: What actual contract wording or evidence would you check before taking this action on your own project?

48. Mixing a notice with a settlement offer — answer a

NEC4 ECC · June 2017 / January 2023

Best next action: Separate the formal notice from the proposed settlement and obtain the necessary legal and commercial review.

Reasoning and source basis: Practical recommendation for human legal review. No conclusion is made that this communication is privileged or protected merely by its label; no settlement is authorised by the quiz.

Evidence to secure: Notice requirements, service route, settlement mandate, draft versions and legal review.

References: HGCRA 1996: service of notices

Reflection: What actual contract wording or evidence would you check before taking this action on your own project?

49. An adjudication notice arrives — answer c

NEC agreement · dispute Option and jurisdiction not yet confirmed

Best next action: Escalate immediately, preserve the complete evidence set and establish jurisdiction, procedure and deadlines.

Reasoning and source basis: Practical urgent escalation. HGCRA section 108 is relevant background only where it applies; no adjudication deadline, jurisdictional conclusion or defence is invented.

Evidence to secure: Notice and receipt, executed dispute provisions, full design history, appointments, insurance and correspondence.

References: HGCRA 1996: adjudication

Reflection: What actual contract wording or evidence would you check before taking this action on your own project?

50. Original stability duty plus an instructed change — answer d

NEC4 ECC · June 2017 / January 2023

Best next action: Protect today’s notice, hold the unchecked sequence and separate original duties from evidenced change effects.

Reasoning and source basis: Integrated practical recommendation using explicit case facts. Establish the instruction’s scope, the relevant event provision, assessed time/cost and the strongest original-obligation counterargument before concluding entitlement.

Evidence to secure: Notice/receipt, original Scope, sequence instruction, checked design, outage programme and segregated cost evidence.
