1
Q
Why was two-stage traditional selected?
A
It allowed early contractor involvement under a PCSA to manage S278 statutory uncertainty and complex phasing, while retaining full client design control — critical due to adjacency to a Grade II* listed building and planning sensitivity.
2
Q
Why was single-stage traditional rejected?
A
It required full RIBA Stage 4 design before contractor appointment, limiting buildability input and increasing programme risk given unresolved Section 278 approval and heritage constraints.
3
Q
Why was Design & Build rejected?
A
Although it provides single-point responsibility, it would have transferred design control to the contractor, risking dilution of architectural quality and potential conflict with heritage and planning expectations, including scrutiny from the Local Planning Authority and Historic England.
4
Q
What is a Section 278 agreement?
A
A legal agreement under the Highways Act 1980 between the developer and Local Highway Authority for works affecting the public highway, requiring technical approval prior to implementation.
5
Q
How did S278 affect programme risk?
A
Highway approval was a statutory dependency; delayed technical approval could prevent planning sign-off and impact the possession date, creating critical path uncertainty.
6
Q
Who were statutory stakeholders?
A
Local Planning Authority, Buckinghamshire Council Highways (LHA), and potentially Historic England due to Grade II* proximity.
7
Q
What is a PCSA and why was it important?
A
A Pre-Construction Services Agreement enabling contractor input into buildability, sequencing, logistics and cost planning prior to contract execution, mitigating design and programme risk.
8
Q
What commercial risks exist in two-stage procurement?
A
Reduced competitive tension at Stage 2, risk of cost escalation, reliance on transparent open-book negotiation and benchmarking.
9
Q
How did you manage Stage 2 cost risk?
A
Through open-book cost planning, detailed subcontractor package interrogation, benchmarking against market rates, and negotiation of preliminaries and OH&P percentages secured at Stage 1.
10
Q
What would happen if Stage 2 negotiations failed?
A
The client could terminate the PCSA and retender, though this would likely impact programme and increase abortive costs.
11
Q
Why JCT SBC Without Quantities 2016?
A
The design was sufficiently developed at contract execution; risk of quantities sat with the contractor rather than remeasurement under a With Quantities form.
12
Q
What is the implication of “Without Quantities”?
A
The contractor prices based on employer’s design information and bears quantity accuracy risk, enhancing cost certainty for the client.
13
Q
How were risks allocated under this strategy?
A
Planning and third-party approval risk remained with the client pre-contract; construction methodology, coordination and programme risk transferred to the contractor upon execution.
14
Q
How did heritage adjacency influence procurement advice?
A
The Grade II* context required preservation of design intent to satisfy planning conditions and potential heritage scrutiny, making D&B less appropriate.
15
Q
How did early contractor involvement mitigate risk?
A
It allowed sequencing of highway works, logistics planning adjacent to a live A404 frontage, and buildability reviews prior to mobilisation.
16
Q
How did you secure competitive tension?
A
Through selective Stage 1 tendering assessing capability, preliminaries, programme and overhead & profit percentages prior to PCSA award.
17
Q
What is the risk of poor PCSA drafting?
A
Undefined scope of pre-construction services can lead to disputes over design responsibility, cost liability and deliverables.
18
Q
What programme mechanism ensured September completion?
A
Agreed contract duration (35 weeks + 2 days) aligned to academic calendar, with risk allowances embedded in sequencing strategy.
19
Q
What would you do differently?
A
I would consider formal risk quantification (e.g., EMV) to better articulate statutory approval risk impact at procurement stage.
20
Q
How did this demonstrate Level 3 competency?
A
I evaluated procurement routes, advised on risk allocation, statutory constraints and programme implications, and presented a structured recommendation enabling informed client decision-making.
21
Q
A
22
Q
How did you identify the project was over budget?
A
Through preparation of an elemental Stage 3 cost plan benchmarked against the approved cost limit, identifying a £116,000 variance.
23
Q
How was the Stage 3 cost plan structured?
A
Elementally in accordance with NRM 1 principles, aligned with RIBA Stage 3 design information.
24
Q
What caused the cost increase?
A
Design development between Stage 2 and Stage 3 including bespoke architectural features, enhanced joinery, oak structural frame and revised M&E strategy.
25
How did you control scope creep?
Through a live cost tracker recording design changes and cumulative cost impacts, reported at design team meetings.
26
Why present three cost control options?
To demonstrate balanced commercial advice, allowing the client to weigh scope, quality and funding implications transparently.
27
Why was scope reduction commercially risky?
Removal of key architectural and landscaping elements risked undermining planning intent, stakeholder expectations and the school’s brand positioning.
28
Why was budget increase constrained?
The project formed part of a wider masterplan with allocated capital expenditure limits and governance approvals.
29
Define Value Engineering technically.
A structured, multidisciplinary review process assessing alternative materials, systems or methodologies to achieve required function at optimum whole-life cost without reducing performance.
30
How did you ensure VE maintained compliance?
By reviewing functional equivalence, performance specifications, durability, lifecycle implications and aesthetic alignment with planning expectations.
31
Why was switching ASHP + UFH to VRF viable?
The Gatehouse scale did not justify underfloor heating complexity; VRF provided sufficient thermal performance with reduced plant space and capital cost.
32
What were M&E risks of the change?
Coordination adjustments, compliance with Part L, lifecycle maintenance considerations and potential acoustic implications.
33
Why change oak to Douglas Fir?
It maintained structural integrity and visual intent while reducing material cost and procurement lead time.
34
What technical considerations apply to timber substitution?
Structural grading, durability classification, treatment requirements and planning acceptability.
35
Why change parquet to LVT?
LVT provided durability, ease of maintenance and cost efficiency while achieving required aesthetic appearance.
36
What lifecycle considerations were assessed?
Maintenance, replacement cycles, cleaning regimes and whole-life value relative to capital saving.
37
Why was the sliding gate saving rejected?
It potentially altered operational functionality and first-impression aesthetics at the main entrance.
38
What was the total accepted VE saving?
£166,271 following rejection of the sliding gate proposal.
39
How did you confirm budget compliance?
Issued revised Stage 3 cost plan incorporating accepted VE measures and confirmed alignment with cost limit.
40
What is the risk of poorly managed VE?
It can reduce performance, create coordination issues or generate long-term cost inefficiencies.
41
How did this demonstrate Level 3 competency?
I led cost analysis, facilitated VE workshops, quantified savings, advised on performance implications and guided the client to a compliant budget solution.
42
Why exactly was two-stage Design & Build rejected?
Two-stage D&B was considered but rejected for three main reasons: • **Design control:** The client and stakeholders required a high level of control over the architectural design due to the sensitive setting near a **Grade II* listed building**, and D&B would have transferred significant design responsibility to the contractor. • **Planning and heritage sensitivity:** The design needed to carefully respond to the heritage setting, so retaining the consultant design team under the client was considered lower risk. • **Scope uncertainty:** The Section 278 highway approval was still progressing, so the client preferred to retain design ownership and flexibility while this statutory process concluded. Therefore, **two-stage traditional allowed early contractor input while preserving design control with the client’s team.**
43
What measures were used to retain design control under two-stage traditional?
Design control was retained through several mechanisms: • The **design team remained appointed directly by the client** and were not novated. • The contractor was engaged under a **PCSA**, meaning they provided buildability advice but had no design responsibility. • The design continued to be developed to **RIBA Stage 4 by the consultant team**. • The contractor’s role was limited to **programme advice, buildability reviews and supply chain input**. This ensured the **client retained design authority throughout the process.**
44
Could a novated design team under D&B have preserved design intent?
Potentially yes, but there are still risks. • Novation transfers the design team to the contractor after contract award. • While the same designers remain involved, **their contractual duty shifts to the contractor rather than the client**. • This can create pressure to **adjust the design to suit contractor cost or buildability priorities**. Given the heritage context and stakeholder involvement, the client preferred to **retain direct contractual control of the designers.**
45
How did early contractor involvement improve the Section 278 submission?
Early contractor involvement improved the S278 process in several ways: • The contractor provided **practical input on highway construction methodology**. • They advised on **traffic management and sequencing of works adjacent to the public highway**. • Their supply chain helped refine the **cost and programme implications of highway works**. This improved the robustness of the submission and reduced the risk of **technical challenges from the highways authority.**
46
What risks did two-stage traditional not transfer that single-stage would have?
Two-stage traditional retained more risk with the client compared to single-stage. Examples include: • **Design risk** remained with the client’s design team. • **Coordination risk between design disciplines** remained client-side. • **Residual statutory approval risk**, such as the Section 278 agreement. Under single-stage D&B many of these risks could be transferred to the contractor, although that would likely have increased their **risk pricing.**
47
What was the payment mechanism under the PCSA?
The PCSA typically operates on a **cost-reimbursable basis with agreed fees**. In this case the contractor was paid for: • **Pre-construction services** • **Programme development** • **Buildability reviews** • **Supply chain engagement** Payment was generally structured as **monthly payments against agreed scope of services**, with an agreed fee covering overhead and profit.
48
How did you ensure second-stage pricing remained competitive?
Several measures helped maintain cost competitiveness: • The **Stage 1 contractor was selected through a competitive tender**. • Supply chain packages were **competitively tendered during Stage 2**. • The contractor’s proposals were benchmarked against the **cost plan and BCIS data**. • The PQS reviewed subcontractor quotes to ensure **market competitiveness**. This helped maintain **cost transparency and market alignment.**
49
Why was VRF a better choice than ASHP technically? How was this assessed?
VRF was considered more suitable due to several technical advantages: • **Greater flexibility** in controlling heating and cooling across different zones. • **Reduced plant space requirements**, which was beneficial given the compact building footprint. • Faster installation compared with wet heating systems. The options were assessed through: • **Mechanical engineer technical analysis** • **Capital cost comparison** • **Spatial requirements for plant** This informed the value engineering decision.
50
Did VE impact the programme?
The value engineering exercise had **minimal programme impact**. • VE was undertaken **during the design stage rather than during construction**. • This allowed the design team to revise specifications without affecting the construction programme. In some cases VE can reduce programme if **simpler construction methods are adopted**, but in this project the primary benefit was cost reduction.
51
How did you quantify cost impacts between RIBA 2 and 3?
Cost changes were quantified through **iterative cost planning**. • A **Stage 2 cost plan** was prepared based on the initial concept design. • As the design progressed to Stage 3, updated design information was measured and re-priced. • Changes were tracked through **elemental cost plan comparisons**. Cost movements were monitored by: • Updating the **cost plan at each design revision** • Highlighting **variance against the approved budget**.
52
Why was scope reduction rejected?
Scope reduction was considered but ultimately rejected due to stakeholder priorities. • The additional elements had been introduced to **meet stakeholder expectations and enhance the design quality**. • Removing them would have undermined the **overall design intent and user experience**. • Instead, the project team focused on **value engineering alternative solutions** rather than removing key design features. This maintained the client’s objectives while still addressing cost pressures.
53
How does a Grade II* listing affect procurement, design, cost and programme?
A Grade II* listing significantly increases project constraints. **Design** • Development must respect the **heritage character and setting**. **Procurement** • May favour routes that **retain design control**, such as traditional procurement. **Cost** • Specialist materials and detailing can increase costs. **Programme** • Additional consultation with planning and heritage bodies can extend timelines.
54
What heritage consultation took place?
Heritage consultation typically involves: • **Local planning authority conservation officers** • **Historic England (if applicable)** • Heritage consultants and architects This ensures the design preserves the **setting and significance of the listed building.**
55
What planning risks were related to heritage?
Key heritage planning risks included: • Objections from conservation authorities. • Design revisions required to protect the **setting of the listed building**. • Potential planning delays if heritage concerns were raised. These risks required **careful design development and stakeholder consultation.**

Grade II* listed building
Particularly important building of more than special interest. Around 5–6% of listed buildings. Protected under Planning (Listed Buildings and Conservation Areas) Act 1990. Requires consent for works affecting character or setting.
71
Why does a listed building matter if works are not directly to it?
Protection includes: Setting, Views, Surroundings. Development can impact how the asset is experienced. Planning authority assesses visual and contextual impact.
72
What is meant by “setting” in heritage terms?
Surroundings in which the asset is experienced. Includes: Views, Access routes, Landscape. Changes can harm significance without physical alteration.
73
What consents may be required for works near a listed building?
Planning Permission. Listed Building Consent (if affecting character/setting). Consultation with conservation officer and LPA.
74
What are key risks when building near a Grade II* listed building?
Damage from vibration/movement. Visual harm to setting. Planning delays. Material incompatibility. Reputational risk.
75
What construction constraints arise near heritage assets?
Restricted access and logistics. Limits on plant and deliveries. Noise and vibration controls. Restricted working hours. Careful sequencing required.
76
How does heritage influence design decisions?
Materials must be sympathetic. Scale and massing must respect existing building. Design often: Blends in OR Is contemporary but sensitive. May require reversibility.
77
Can modern materials be used near listed buildings?
Yes, if: Justified, Sympathetic or respectfully contrasting. Typically requires planning approval. Must not harm significance.
78
How does heritage impact cost?
Specialist materials increase cost. Skilled labour required. Slower construction methods. Increased design development time. Higher risk allowances.
79
How does heritage impact programme?
Longer planning and approvals. Design iterations. Restricted working methods. Potential delays due to compliance issues.
80
How does heritage scrutiny impact programme and cost certainty?
Programme: Extended approvals (planning + conservation). Increased design development time. Risk of delays due to objections or revisions. Cost certainty: Reduced due to evolving design requirements. Higher contingency needed. Unknowns around materials, methods, and approvals. Overall: Greater uncertainty compared to standard projects.
81
What are the commercial risks of heritage constraints?
Increased preliminaries due to longer programme. Potential for variations from design changes. Higher contractor risk pricing. Delay-related costs.
82
How did you add value as a QS in a heritage context?
Reflected heritage requirements in cost plan. Advised on cost of material choices. Balanced cost vs quality vs compliance. Identified programme and cost risks early.
83
Why is design control important in heritage projects?
Ensures aesthetic and contextual suitability. Prevents inappropriate contractor-led changes. Maintains compliance with planning requirements.
84
Why was two-stage traditional procurement suitable for a heritage project?
Allows early contractor involvement. Provides buildability input in constrained setting. Helps manage programme risk. Retains design control for heritage sensitivity.
85
How would you justify value engineering on a heritage-sensitive project?
VE must not compromise: Character, Setting, Planning compliance. I would: Engage with architect + conservation officer, Ensure alternatives are sympathetic in appearance and performance. Focus on: Hidden elements (services, structure, build-ups). 👉 Line: “Value engineering in heritage projects is about reducing cost without reducing significance.”
86
What would you do if the contractor proposes a cheaper alternative that conflicts with heritage intent?
Assess: Compliance with planning/heritage requirements. Reject if it compromises: Aesthetic or significance. Consult: Design team + conservation officer. Only accept if: Equivalent in performance AND visual impact. 👉 Line: “Cost savings cannot override statutory or heritage requirements.”
87
Who is responsible for ensuring heritage compliance?
Ultimately: Client + design team. Key roles: Architect → design compliance, Conservation officer → approval, Contractor → execution, QS → advise on cost implications. 👉 Strong close: “My role is to ensure the client understands the commercial implications of compliance.”
88
How would heritage constraints influence your risk allowance?
Increase contingency due to: Unknown site conditions, Approval risks, Design development. Use: Risk register + EMV (if appropriate). Regularly review as design develops.
89
What happens if you damage a listed building during construction?
Immediate: Stop works, Notify client + authorities. Legal implications under Planning (Listed Buildings and Conservation Areas) Act 1990. Potential: Criminal offence, Fines, Requirement to reinstate. 👉 This is a BIG one — say “criminal offence” confidently.
90
How does heritage affect contractor pricing?
Contractors include: Higher risk allowances, Specialist labour costs, Programme allowances. Reduced productivity due to constraints. Potential limited contractor pool → less competition.
91
Would you expect more variations on a heritage project?
Yes, due to: Design development, Unforeseen conditions, Planning-driven changes. Requires: Strong change control.
92
How would you manage cost certainty in a heritage project?
Develop detailed cost plan aligned with design. Include appropriate contingency. Engage contractor early (ECI). Regular cost reporting and risk reviews. 👉 Line: “Cost certainty improves as heritage risks are progressively resolved.”
93
Why might a client accept higher costs on a heritage project?
Planning compliance is mandatory. Protects asset value and reputation. Long-term value outweighs short-term savings.
94
How does working near a listed building affect preliminaries?
Increased prelims due to: Longer programme, Restricted working methods, Additional protection measures, Logistics challenges. 👉 Tie back to your earlier prep (you’ve smashed this topic already).
95
What is the role of the conservation officer?
Advises LPA on heritage matters. Reviews: Design proposals, Materials, Impact on significance. Influences planning approval.
96
How would you explain heritage constraints to a non-technical client?
Simple explanation: “We need to protect the appearance and significance of the building and its surroundings.” Then link to: Cost, Programme, Risk. 👉 This is testing client care (Level 2).
97
Could heritage requirements impact procurement strategy?
Yes: Need for early contractor involvement, Importance of design control. Routes like: Two-stage traditional preferred. Avoid: Early contractor design control (e.g. D&B risk).
98
How does heritage link to sustainability?
Retaining and respecting existing assets is: Environmentally sustainable (less demolition). However: Upgrading performance (e.g. energy) can be constrained. 👉 Nice bonus point if you mention this.
99
What’s the difference between preserving and conserving?
Preservation: Keeping exactly as is. Conservation: Managing change in a way that protects significance. 👉 Line: This is a CLASSIC tricky one.
100
Listed Building Consent (LBC)
Formal consent required for works affecting a listed building. Covers: Alteration, Extension, Demolition. Required under Planning (Listed Buildings and Conservation Areas) Act 1990. Applies to: Fabric **and setting**.
101
Why was Listed Building Consent required on your project?
Works impacted the **setting of a Grade II* listed building**. The new entrance altered: How the building is approached, How it is visually experienced. Therefore: Considered to affect its **significance**.
102
What types of works typically require Listed Building Consent?
Internal alterations affecting character, External alterations (materials, appearance), Extensions or new structures nearby, Demolition (full or partial).
103
What happens if you carry out works without Listed Building Consent?
It is a **criminal offence**. Can result in: Fines, Enforcement action, Requirement to reinstate works.
104
Who grants Listed Building Consent?
Local Planning Authority (LPA). Advised by: Conservation officer, Sometimes Historic England.
105
What information is required for a Listed Building Consent application?
Heritage statement, Design and access statement, Drawings and specifications, Justification of works, Impact assessment on significance.
106
What is a Heritage Statement?
Document explaining: Significance of the asset, Impact of proposed works. Justifies why works are acceptable.
107
How long does Listed Building Consent typically take?
Usually aligned with planning: **8–13 weeks** typical. Can be longer if: Complex heritage issues, Objections, Design revisions required.
108
How did Listed Building Consent impact your programme?
Required: Early design finalisation, Submission before construction. Risk of: Delays if approval not granted. Influenced need for: Early contractor involvement.
109
How did Listed Building Consent impact cost certainty?
Reduced certainty due to: Ongoing design development, Potential planning conditions, Unknown approval outcomes. Required: Higher contingency.
110
What conditions might be attached to Listed Building Consent?
Approval of specific materials, Construction methods, Protection measures, Archaeological requirements, Sample panels/mock-ups.
111
How does Listed Building Consent differ from Planning Permission?
Planning Permission: Focuses on development and land use. Listed Building Consent: Focuses on **heritage impact and significance**. Both may be required simultaneously.
112
What role does the QS play in relation to Listed Building Consent?
Advises on: Cost implications of heritage requirements. Reflects: Design constraints in cost plan. Allows for: Programme and risk impacts.
113
How could Listed Building Consent impact procurement?
Drives need for: Early contractor involvement. Influences: Programme sequencing. Supports: Retaining design control.
114
Could you have avoided needing Listed Building Consent?
Only if: No impact on character or setting. In this case: Not possible due to entrance works affecting setting.
115
What would you do if consent was refused?
Review reasons for refusal, Amend design to address concerns, Resubmit application, Consider programme impact.
116
When should Listed Building Consent be applied for?
During design development (typically Stage 3–4), Before construction begins, Early submission reduces programme risk.
117
How does LBC link to your procurement decision?
Risk of delayed approvals → programme uncertainty. Two-stage allowed: Progression of design, Contractor input while awaiting approval.
118
Your perfect story (use this)
“Listed Building Consent was required as the works impacted the setting of a Grade II* listed building, particularly at the main entrance which influenced how the asset is experienced. This introduced programme risk due to statutory approval timelines and reduced cost certainty due to ongoing design development and potential conditions. I reflected this in the cost plan through contingency allowances and supported a two-stage procurement route to allow early contractor input while maintaining design control.”
