17
Q
What is a Payment Notice?
A
A Payment Notice sets out the sum the payer considers due and the basis on which it is calculated.
18
Q
What is a Pay Less Notice?
A
A Pay Less Notice allows the payer to pay less than the notified sum, provided it is issued within the contractual timeframes and sets out the calculation basis.
19
Q
What is the notified sum?
A
The notified sum is the amount stated in a valid Payment Notice or, if none is issued, the contractor’s application.
20
Q
What happens if a valid Pay Less Notice is not issued?
A
The payer must pay the notified sum, even if it is considered incorrect.
21
Q
Why should you not certify work that has not been carried out?
A
Certifying uncompleted work could result in overpayment, increased insolvency risk and potential professional negligence exposure.
22
Q
How would you defend your valuation in adjudication?
A
By relying on contemporaneous records, site inspections, photographs, marked-up drawings, contractual provisions and a clear audit trail.
23
Q
What is retention?
A
Retention is a percentage withheld from interim payments as security against defective or incomplete works, typically released at Practical Completion and at the end of the defects period.
24
Q
What is novation in Design and Build?

58
What documents form the contract under JCT Design and Build 2016?
The Contract Agreement, Contract Conditions, Schedule of Amendments, Employer’s Requirements, Contractor’s Proposals, Contract Sum Analysis, and the Contract Particulars.
59
What is the purpose of the Contract Particulars?
The Contract Particulars record project-specific information such as retention percentage, rectification period, sectional completion dates, interim valuation dates and liquidated damages.
60
How did you ensure the Contract Particulars were accurate before execution?
I cross-checked them against agreed commercial terms, tender clarifications and the Schedule of Amendments, ensuring dates, percentages and project-specific details reflected the negotiated position.
61
What is the purpose of the Contract Sum Analysis under D&B?
The CSA provides a breakdown of the contract sum, enabling interim valuations, variation assessment and financial monitoring during the project.
62
How did you use the Contract Sum Analysis during interim valuations?
I used it to assess progress against cost headings, allocate value to completed works and benchmark the contractor’s application against agreed cost breakdowns.
63
What steps did you take when reviewing an interim application?
I reviewed the contractor’s submission, inspected site progress, cross-checked against drawings and the CSA, verified supporting evidence and ensured compliance with contractual payment provisions.
64
How did you ensure compliance with payment timelines?
I diarised the Interim Valuation Dates, due dates and final dates for payment in line with the contract and ensured payment recommendations were issued within those timeframes.
65
What is the risk of missing the due date for a Payment Notice?
The contractor’s application may become the notified sum under the Construction Act, making it payable unless a valid Pay Less Notice is served.
66
How do you determine the value of work properly executed in a period?
Through site inspection, measurement where required, reviewing progress against programme and assessing value against the CSA and contract rates.
67
How did you ensure fairness when preparing payment recommendations?
I assessed the application objectively against actual progress and contract provisions, ensuring neither over- nor under-certification occurred.
68
What is the purpose of retention?
Retention provides security to the Employer against defective or incomplete works and is typically released in stages in accordance with the contract.
69
How is the Rectification Period determined?
It is agreed in the Contract Particulars at contract execution and defines the period during which the contractor must return to remedy defects.
70
How did you prepare for final account negotiations?
I collated all variation instructions, supporting drawings, cost breakdowns, site records and previous valuation assessments to ensure a clear audit trail before entering negotiations.
71
What is the purpose of final account negotiations?
To agree the final contract sum reflecting all instructed variations, adjustments and agreed claims prior to issuing the Final Statement.
72
How did you approach negotiation with the contractor at final account stage?
I reviewed substantiation, challenged unsupported costs, referred back to contractual valuation mechanisms and sought a commercially reasonable and evidence-based agreement.
73
If the contractor disputes a variation valuation at final account stage, how would you respond?
I would refer to the contract valuation provisions, review supporting evidence and, if necessary, attempt resolution through negotiation before escalation to dispute resolution mechanisms.
74
What is the Statement of Final Account?
It is the formal document setting out the agreed final contract sum, typically signed by both parties to confirm settlement.
75
Why is documentation critical at final account stage?
Clear documentation supports transparency, reduces dispute risk and provides a defensible position should adjudication arise.
76
How do variations impact the final account?
They adjust the original contract sum and must be valued in accordance with the contract, either using agreed rates or fair valuation methods.
77
What would you do if agreement cannot be reached at final account stage?
I would attempt further negotiation and, if unresolved, advise the Client on dispute resolution options such as adjudication in accordance with the contract.
78
How does the Schedule of Amendments affect contract administration?
It may modify standard JCT provisions, so I review it carefully to ensure payment, notice and risk allocation procedures are administered correctly.
79
What is your role in ensuring the contract documents are aligned before execution?
I ensure consistency between Employer’s Requirements, Contractor’s Proposals, CSA and amendments to avoid ambiguity or scope gaps.
80
What practical skills did you demonstrate at Level 2 in this experience?
Contract document collation, payment administration, valuation assessment, compliance with statutory timelines, evidence-based negotiation and final account agreement.

Could you partially include the item?
* Only if some measurable work had been completed
* Otherwise, no value = no payment
132
What would you do differently next time?
* Ensure clearer communication with contractor early
* Monitor site progress more closely before valuation
* Pre-empt potential overclaims
133
How does this link to cost control?
* Prevents overpayment and budget creep
* Maintains accurate cost reporting
* Supports financial control throughout construction
134
What is the difference between application and valuation?
