Case study Level 1 Focus

Question 1

What is meant by “contract administration” in construction?

Answer 1

It is the process of managing and implementing the contract between the employer and contractor to ensure each party fulfils its obligations under the contract terms

Question 2

What is the main purpose of contract administration under JCT Design & Build 2016?

Answer 2

To ensure the contract is carried out in accordance with its conditions — including time, cost, quality and procedural requirements — through proper notices, certification and record-keeping.

Question 3

What are the key functions of the Employer’s Agent under JCT D&B?

Answer 3

To administer the contract on behalf of the employer by issuing instructions, assessing payments and extensions of time, and certifying completion while acting fairly and independently

Question 4

What are the main contract documents within the JCT D&B 2016?

Answer 4

Articles of Agreement, Contract Particulars, Conditions, Employer’s Requirements (ERs), Contractor’s Proposals (CPs), and the Contract Sum Analysis.

Question 5

Explain the relationship between the Employer, Employer’s Agent and Contractor.

Answer 5

The Employer contracts directly with the Contractor; the Employer’s Agent acts as the Employer’s representative and administrator for issuing instructions and certificates.

Question 6

What is an instruction under JCT D&B, and who issues it

Answer 6

An instruction is a formal direction issued by the Employer’s Agent to the Contractor requiring a change or clarification permitted by the contract.

Question 7

What constitutes a variation under JCT D&B 2016?

Answer 7

A variation is an instructed change to the Employer’s Requirements that alters the design, quality, quantity or sequence of the works and may entitle cost and/or time adjustments.

Question 8

What is the procedure for interim payments under JCT D&B?

Answer 8

The Contractor submits an application; the Employer’s Agent issues a Payment Notice by the due date; payment is made by the final date unless a Pay Less Notice is served.

Question 9

What are Relevant Events and Relevant Matters?

Answer 9

Relevant Events relate to time entitlement (e.g., weather, variations); Relevant Matters relate to cost entitlement for loss and expense.

Question 10

What is Practical Completion and why is it significant?

Answer 10

It is the stage when the works are complete for their intended use; at that point liquidated damages cease, retention is released, and the defects liability period begins

Question 11

What key notices are required under JCT D&B 2016?

Answer 11

Examples include payment notices, pay less notices, extension-of-time applications, loss and expense claims, instructions and completion certificates.

Question 12

What are the implications of failing to issue a payment notice?

Answer 12

Under the Housing Grants, Construction and Regeneration Act 1996, the amount applied for by the Contractor becomes payable by default if no notice is issued on time.

Question 13

What certificates are issued during the contract life cycle?

Answer 13

Certificates for interim payments, Practical Completion, Non-Completion, Making-Good Defects, and the Final Certificate

Question 14

What is the process for determining an Extension of Time?

Answer 14

The Contractor notifies a Relevant Event; the Employer’s Agent reviews evidence and issues a revised completion date if entitlement is established.

Question 15

What is the purpose of the retention mechanism?

Answer 15

Retention protects the Employer by withholding a percentage of payments to ensure defects are rectified and works completed satisfactorily

Question 16

What are the main duties of the Contractor under JCT D&B 2016?

Answer 16

To complete the works in accordance with the Employer’s Requirements and Contract Documents, comply with all instructions, and assume design liability where required.

Question 17

What is the difference between the Employer’s Agent and the Contract Administrator under traditional JCT contracts?

Answer 17

The CA acts as an independent certifier in traditional contracts; the EA in D&B represents the Employer but still acts fairly when certifying matters.

Question 18

How is design responsibility allocated under JCT D&B

Answer 18

The Contractor is responsible for design and construction based on the Employer’s Requirements and their own Contractor’s Proposals.

Question 19

What other standard forms of contract are you aware of outside JCT?

Answer 19

NEC 4 Engineering and Construction Contract, ICE conditions, FIDIC, PPC 2000 and JCLI are commonly used in civil engineering and international projects.

Question 20

How does NEC 4 differ in philosophy from JCT D&B 2016?

Answer 20

NEC is written in plain language, emphasises collaboration and early warning management, while JCT is more traditional and reactive with separate certification roles.

Question 21

What is Loss and Expense under JCT Design & Build 2016?

Answer 21

“Loss and Expense” is additional cost incurred by the contractor due to events for which the employer is responsible, causing disruption or delay to the regular progress of the works.

Question 22

What is a relevant event and what are the types of events ?

Answer 22

Relevant Events – Time Entitlement

Relevant Events are the causes of delay that may entitle the contractor to an Extension of Time (EoT) but not automatically additional cost.
They protect the contractor from liquidated damages when the delay is beyond their control.

The main Relevant Events include:

Variations instructed by the Employer’s Agent.

Late issue of instructions or information from the Employer.

Exceptionally adverse weather conditions.

Strikes or civil commotion.

Loss or damage due to specified perils (fire, flood, etc.).

Statutory undertakers’ delays.

Delay in giving possession of the site.

Employer’s suspension of the works.

Any impediment, prevention, or default by the Employer.

Force majeure.

Outcome: Contractor receives more time, not necessarily more money

Question 23

What is a relevant matter and what are the types of events ?

Answer 23

Relevant Matters are the employer-risk events that cause disruption or prolongation, entitling the contractor to recover proven additional costs (loss and expense).

The main Relevant Matters include:

Variations instructed by the Employer’s Agent.

Failure by the Employer to give possession or access on time.

Late instructions, information, or decision by the Employer.

Suspension of the works by the Employer.

Delay caused by nominated subcontractors or direct contractors.

Impediment, prevention, or default of the Employer.

Outcome: Contractor receives money, but only when actual loss is demonstrated and properly ascertained.

Question 24

What are the available JCT contract Suites and when would you use them ?

Answer 24

he JCT suite provides standard forms to suit different procurement routes, project scales, and risk profiles:

JCT Home Owner Contracts – for small domestic works where the client is a private individual; simple language and minimal administration.

JCT Minor Works (MW) – for straightforward, low-risk projects where the design is provided by the employer’s consultant; typically below £1 million.

JCT Intermediate Building (IC) – for medium projects requiring more detailed provisions, schedules of rates, and partial contractor design; roughly £1–5 million range.

JCT Standard Building Contract (SBC) – the traditional form for larger, complex projects with full consultant design and separate architect/CA administration; often £5 million +.

JCT Design & Build (DB) – used where the contractor takes single-point responsibility for both design and construction; ideal for clients wanting cost certainty and simplified administration.

JCT Major Project Construction (MP) – a streamlined design-and-build contract for experienced clients on high-value projects (typically £20 million +).

JCT Management Building Contract (MC) – where a management contractor engages trade contractors on the employer’s behalf, suitable for large, multi-package schemes.

JCT Construction Management (CM) – where the employer contracts directly with trade contractors and appoints a construction manager to coordinate them; used for fast-track complex builds.

JCT Measured Term (MTC) – for maintenance, repair, or rolling programme works over a period rather than a single project.

Question 25

what are the difference between JCT and NEC

Answer 25

JCT The JCT contracts are traditional, prescriptive and event-driven. They allocate risk through defined clauses such as Relevant Events and Matters, rely on certification after the event, and use formal notices and valuations. Language is legalistic, and relationships are clearly separated — the Employer’s Agent or Architect administers impartially but at arm’s length. Time and cost adjustments are reactive; disputes often arise over interpretation. NEC The NEC contracts are modern, proactive and management-focused. They promote collaboration and early warning to manage risk before it materialises. The Project Manager has an active day-to-day role, using tools such as the Early Warning Register and a live programme. Change control occurs through Compensation Events, agreed contemporaneously to adjust both time and cost. Language is plain English, and the emphasis is on teamwork, flexibility, and transparency. In essence: JCT manages what has happened; NEC manages what might happen.

Question 26

What are the available NEC contract Suites and when would you use them ?

Answer 26

The NEC (“New Engineering Contract”) suite, now at NEC 4 edition, provides a family of contracts used across construction, engineering, and service industries. All are written in plain English and built on the principles of collaboration, proactive management, and clarity. The suite includes: Engineering and Construction Contract (ECC) – the core contract for building and civil engineering works. It has six main payment options (A – F) ranging from lump-sum to management arrangements. Engineering and Construction Subcontract (ECS) – mirrors the ECC for subcontractors. Professional Services Contract (PSC) – for consultants such as QSs, designers, and project managers. Term Service Contract (TSC) – for ongoing maintenance or FM services over a period. Framework Contract (FC) – to establish long-term collaborative arrangements. Supply Contract (SC) – for the purchase of major equipment or materials. Alliance Contract (ALC) – for fully integrated project teams with shared risk and reward. Design-Build and Operate Contract (DBO) – for projects where the contractor designs, builds, and operates the facility for a term. All NEC forms share: a common structure of core clauses + Option clauses; an Early Warning system to identify and mitigate risk; a live, updateable programme as the management tool; and Compensation Events, which adjust both time and cost in real time rather than retrospectively. Summary sentence to memorise: The NEC suite promotes proactive management, collaboration and transparency, whereas JCT provides traditional certainty through prescriptive procedures and post-event certification.

Question 27

Why a Relevant Event Can Lead to Additional Cost

Answer 27

While Relevant Events entitle only time under the JCT mechanism, some events (like variations or employer default) are also listed as Relevant Matters. This overlap means the same circumstance can justify both an Extension of Time (protecting the contractor from delay damages) and Loss and Expense (reimbursing the contractor’s proven extra cost). However, payment is not automatic — the contractor must evidence that costs were reasonably and necessarily incurred because of the delay or disruption caused by the employer-risk event.

Question 28

What is the difference between a Relevant Event and a Relevant Matter?

Answer 28

A Relevant Event gives entitlement to time (Extension of Time); a Relevant Matter gives entitlement to money (loss and expense).

Question 29

Give three examples of Relevant Events under JCT D&B 2016.

Answer 29

Variations, exceptionally adverse weather, and loss or damage from specified perils

Question 30

Give three examples of Relevant Matters under JCT D&B 2016.

Answer 30

Late instructions, failure to give possession of site, and suspension by the employer.

Question 31

Why might a contractor receive additional cost following a Relevant Event?

Answer 31

Because while the event initially grants time, if it also causes genuine prolongation costs or disruption directly attributable to employer risk, those costs are recoverable under the loss-and-expense provisions linked to the same event

Question 32

How is loss and expense established under JCT D&B 2016?

Answer 32

The contractor must give notice, provide evidence of actual additional cost, and the Employer’s Agent ascertains a reasonable amount under clauses 4.20–4.23.

Question 33

Name three principal NEC contract options.

Answer 33

NEC 4 ECC Option A (Lump Sum), Option C (Target Cost), and Option E (Cost Reimbursable).

Question 34

When might a client choose NEC over JCT?

Answer 34

When the project demands close collaboration, real-time programme management, and transparent risk-sharing — typical in civil engineering or infrastructure works.

Question 35

What are the main sections of the JCT Design & Build 2016 contract and their purpose

Answer 35

The contract is arranged into nine sections that set out the obligations of both parties. Section 1 – Carrying out the Works – defines commencement, possession, and instructions (clauses 1.7 – 2.15). Section 2 – Contractor’s Designed Portion – design responsibility and PI insurance (2.17 – 2.25). Section 3 – Control of the Works – site standards, materials, workmanship. Section 4 – Payment – valuations, notices, loss & expense (4.7 – 4.23). Section 5 – Variations – defines and values changes (5.1 – 5.7). Section 6 – Injury, Damage & Insurance – insurance options A–C. Section 7 – Assignment & Third-Party Rights – warranties, step-in rights. Section 8 – Termination – employer/contractor rights (8.4 – 8.12). Section 9 – Settlement of Disputes – adjudication/arbitration (9.1 – 9.3). Purpose / What to Know: Always be able to say “Payment = Section 4; EoT = 2.26; Loss & Expense = 4.20.”

Question 36

How are interim payments managed under JCT D&B 2016?

Answer 36

The contractor applies for payment; the Employer’s Agent issues a Payment Notice by the due date; if the Employer intends to pay less, a Pay-Less Notice must be served before the final date for payment. Purpose: Ensures compliance with the Housing Grants Act 1996 and maintains cash-flow. Clauses: 4.7 – 4.15.

Question 37

What is Loss and Expense and when is it paid?

Answer 37

It compensates the contractor for additional cost arising from Relevant Matters (late instructions, employer delays, etc.). The contractor must notify, substantiate and the EA must ascertain the reasonable amount. Clauses: 4.20 – 4.23. Purpose: To reimburse proven prolongation or disruption costs due to employer-risk events.

Question 38

What is a Relevant Event?

Answer 38

A circumstance beyond the contractor’s control (e.g. variations, adverse weather, employer default) giving entitlement to an Extension of Time. Clauses: 2.26 – 2.29. Purpose: Adjusts the completion date and relieves the contractor of liquidated damages

Question 39

What is the difference between Relevant Events and Relevant Matters?

Answer 39

Events = time entitlement; Matters = money entitlement. Some items (e.g. variations) appear in both lists.

Question 40

What happens at Practical Completion?

Answer 40

The EA certifies that the works are fit for use; LADs stop, half retention is released, and the defects period begins. Clause: 2.30.

Question 41

What is a Variation and how is it valued?

Answer 41

A change to the Employer’s Requirements instructed by the EA under clause 5.1. It’s valued using contract rates, fair valuation, or dayworks; may also trigger time or cost entitlement. Purpose: To maintain cost/time certainty while allowing controlled design change.

Question 42

What is an Instruction?

Answer 42

A written direction from the Employer’s Agent to the Contractor under clause 2.12; must be in writing and within authority. Purpose: Provides formal authority to act; keeps communication auditable.

Question 43

How does JCT allocate risk for injury and damage?

Answer 43

Section 6 sets out insurance obligations (Options A–C) covering new works, existing structures, and liability for injury or property damage. Purpose: To ensure proper insurance cover and risk allocation between employer and contractor.

Question 44

When can the employer or contractor terminate the contract?

Answer 44

Employer: contractor insolvency, non-performance, failure to proceed diligently (8.4–8.12). Contractor: non-payment, prolonged suspension, employer default. Purpose: To allow lawful exit and define consequences.

Question 45

How are disputes resolved under JCT D&B 2016?

Answer 45

Through adjudication (statutory right), or by arbitration/litigation as stated in the Contract Particulars (Section 9). Purpose: Provides statutory and contractual routes for quick or final resolution

Question 46

Memorize Tips for JCT Numbers

Answer 46

Associate numbers with themes: “2 = Time & design”, “4 = Money”, “5 = Change”. Practise verbal recall: “Clause 2.26 – Extension of Time; Clause 4.20 – Loss & Expense; Clause 5.1 – Variation.”

Question 47

What are the essential components of a valid contract

Answer 47

Offer, Acceptance, Consideration, Intent to create legal relations and Capacity

Question 48

What are the key changes from JCT 2016 and JCT 2024

Answer 48

he 2024 edition introduces a clause requiring the parties to work in good faith and in a spirit of trust and respect, making collaborative working a standard commitment rather than optional. The contractor’s design liability clause (Clause 2.17 in 2016) has been re-worked so that the contractor is no longer subject to a “fit for purpose” duty: instead the obligation is to exercise “reasonable skill and care (to the extent permitted by the Statutory Requirements)”. The list of “Relevant Events” (for extension of time) and “Relevant Matters” (for loss & expense) has been expanded — for example, delays caused by epidemics, changes in law, contaminated land/asbestos/unexploded ordnance now feature explicitly. Notices and communications: JCT 2024 allows notices to be sent by email in many cases (if the Contract Particulars so provide) and uses updated gender-neutral language throughout. The Building Safety Act 2022 / new dutyholder regime is recognised: for example a new Article 7 appoints Principal Designer and Principal Contractor under Part 2A of the Building Regulations, and Clause 3.16 is amended to include dutyholder obligations. Timelines for Extensions of Time have been shortened: the employer must respond to an extension of time application within 8 weeks (instead of 12) in many cases. Some supplemental provisions in the 2016 edition (collaborative working, sustainability etc) are now integrated as main contract obligations in 2024 rather than being optional

Question 49

When does JCT Design & Build 2016 stop being used?

Answer 49

There is no automatic expiry date for the 2016 edition. Contracts negotiated using JCT 2016 remain valid and enforceable if parties have adopted them. However, the 2024 edition was published in April 2024 (Design & Build 2024 and Sub-contract) and is the current edition. In practice, for new projects, many clients and contractors will move to the 2024 edition to reflect the latest legislative and risk landscape. For older procurement documents or contracts in negotiation that chose 2016, the 2016 edition may still be used — but you should beware the risk of using a ‘dated’ form given new obligations (e.g., dutyholder roles, epidemics, sustainability) are embedded in the 2024 edition. For your APC preparation: you should be familiar with both editions (2016 and 2024) — especially since your summary says you have understanding of the 2016 suite. But be ready to comment on the 2024 changes and how they affect contract admin.

Question 50

Tell me about the new JCT Design and Build Contract 2024, and why would you use it instead of the 2016 version?

Answer 50

“The JCT Design and Build 2024 is the latest update to the JCT suite, published in April 2024, replacing the 2016 edition. It reflects key legislative and industry developments — most notably the Building Safety Act 2022, dutyholder roles, and a stronger emphasis on collaborative working. The 2024 version introduces several key changes: A new express duty for both parties to act in a spirit of trust, collaboration, and mutual respect. Design liability clarified to confirm the contractor’s duty is one of reasonable skill and care, removing any ambiguity over “fitness for purpose”. New Relevant Events and Matters for things like epidemics, contaminated land, and changes in law. Integration of building safety obligations — for example, appointment of the Principal Designer and Principal Contractor under Article 7 and Clause 3.16. Improved digital communication provisions — email notices are now permitted (if stated in Contract Particulars). Simplified timeframes for Extensions of Time, reducing response periods from 12 to 8 weeks. I would advise using the JCT 2024 form for new projects because it is up to date with current legislation, particularly around building safety and modern risk allocation. It also encourages a more proactive, transparent, and collaborative approach to project delivery. The JCT 2016 form remains valid and can still be used, especially for ongoing frameworks or negotiations, but it lacks explicit recognition of these legislative changes. For new tenders, adopting 2024 ensures alignment with statutory obligations and current best practice

Question 51

“Suppose your client has an established procurement template based on JCT Design & Build 2016, but you’re aware the 2024 edition has been released. How would you advise them?”

Answer 51

“I would first review the project context — size, complexity, and risk profile — and then advise the client that the JCT 2016 form remains legally valid but does not incorporate the latest statutory and industry updates. I’d highlight key differences: The Building Safety Act 2022 places new dutyholder obligations on clients, designers, and contractors, which are recognised directly in JCT 2024 but missing from JCT 2016. The good-faith and collaboration clause in 2024 promotes modern project behaviours. Digital communication (email notices) and the revised design liability wording reflect current practice and reduce ambiguity. I would present these points as part of a risk comparison note, advising that while it’s possible to amend a 2016 form to include similar provisions, adopting the 2024 edition provides a more straightforward and compliant solution for new procurements. Ultimately, I’d recommend transitioning to the 2024 version for new contracts to align with legislative compliance and best practice, while allowing existing projects under 2016 to run to completion

Question 52

After a valuation and payment certificate are issued, the client says they don’t have sufficient funds to pay. What should you do?

Answer 52

As Employer’s Agent, I must act impartially under the contract but also alert the client to their contractual obligation. I’d confirm that the certificate is a binding obligation under Clause 4.13 (JCT D&B 2016). Advise the client that non-payment constitutes a breach and may give the contractor the right to suspend the works under Section 112 of the Housing Grants, Construction & Regeneration Act 1996. I would notify both parties in writing, check the valuation’s validity, and seek to agree a funding plan while maintaining proper records. Persistent non-payment can lead to termination by the contractor under Clause 8.9.

Question 53

If an instruction involves fabrication of substantial materials off-site, can they be included in a valuation?

Answer 53

Only if the contract allows payment for off-site materials (Clause 4.13.1). Before including them: Ensure ownership passes to the Employer (e.g., through vesting certificates). Confirm the materials are appropriately identified, insured, and stored separately. Obtain evidence such as invoices or photographs. Without these conditions, they would not normally be valued.

Question 54

What is frustration in contract law?

Answer 54

Frustration occurs when an unforeseen event makes performance impossible or radically different from what was agreed, through no fault of either party. Example: destruction of the site before commencement. When frustration occurs, the contract is automatically discharged, and both parties are released from further obligations. It’s rare in construction due to detailed risk provisions in JCT and NEC forms.

Question 55

How is a contract under hand different from a deed?

Answer 55

A contract under hand (simple contract) requires consideration and has a limitation period of 6 years. A deed does not require consideration and has a limitation period of 12 years. JCT contracts are normally executed as deeds to extend liability for latent defects and design responsibilities.

Question 56

What are latent defects, and what issues arise from them?

Answer 56

Latent defects are hidden faults not discoverable by reasonable inspection at completion, such as structural weaknesses or design errors. Issues: Liability may arise years later, hence longer limitation under a deed. Standard JCT contracts do not provide an ongoing warranty; recovery is through collateral warranties or latent defect insurance. Distinguish from patent defects, which are visible and must be rectified during the defects period.

Question 57

What is the difference between defined and undefined provisional sums?

Answer 57

A defined provisional sum is one where the nature and extent of the work are described, and allowance for time, cost, and design risk is included in the programme and prelims. An undefined provisional sum lacks sufficient detail to allow pricing or programming. Time and risk: Defined PS — contractor deemed to have allowed for time implications. Undefined PS — may justify an extension of time when instructed. Risks: inaccurate budgeting, programme disruption, and potential disputes if scope grows beyond expectation.

Question 58

What are the key parts of a JCT Design & Build Contract?

Answer 58

Articles of Agreement Contract Particulars Conditions (Sections 1–9) Employer’s Requirements Contractor’s Proposals Contract Sum Analysis Schedules and Supplemental Provisions Together these define obligations, price, and risk allocation.

Question 59

Name the nine sections.

Answer 59

1️⃣ Carrying Out the Works 2️⃣ Contractor’s Design 3️⃣ Control of the Works 4️⃣ Payment 5️⃣ Variations 6️⃣ Injury, Damage and Insurance 7️⃣ Assignment and Third-Party Rights 8️⃣ Termination 9️⃣ Settlement of Disputes

Question 60

What are the advantages and disadvantages of using standard forms over bespoke contracts?

Answer 60

Advantages: Widely understood and accepted in industry. Balanced risk allocation based on case law. Lower legal costs and fewer drafting errors. Easier administration and benchmarking. Disadvantages: May not fully reflect project-specific risks. Repetitive amendments can create hybrid contracts that lose clarity. Some terms may not suit complex financing or specialist projects.

Question 61

What are the advantages and disadvantages of JCT and NEC contracts?

Answer 61

JCT (Design & Build) ✔ Familiar, legally tested, suits building works and employer design control. ✔ Clear certification procedures. ✖ Can be reactive and adversarial; less suited to fast-track or complex risk-sharing. NEC (ECC) ✔ Promotes collaboration, proactive risk management, and contemporaneous change control. ✔ Flexible (Options A–F) and ideal for infrastructure or partnering. ✖ Requires experienced management and disciplined programming; administrative burden higher.
