Technical Competency Reference Guide
What assessors test in each competency area — mapped to evidence types and Level 3 indicators. Use this to identify your highest-risk areas before each coaching session.
What Level 3 Looks Like — Competency by Competency
| Competency | Level 3 requires | Evidence that demonstrates it | Common Level 2 mistake |
|---|---|---|---|
| Commercial Management | Advising the client on their commercial position and exposure — identifying risks before they become problems, recommending strategies to protect the client's financial interests | Specific situation where professional advice changed the client's commercial outcome. Describe the risk, the advice, and the consequence of the advice being given (or not given) | Describing the commercial management tasks performed without connecting them to client outcomes or professional recommendations |
| Cost Planning | Advising the client on the relationship between design decisions and budget — identifying cost risk at each RIBA stage and making recommendations about how to manage it | Example of identifying a cost driver in an emerging design and presenting the client with options and professional recommendations — not just a cost plan that was "within budget" | Describing the production of cost plans without explaining what professional advice the cost plan informed |
| Cost Reporting and Financial Control | Giving the client an integrated picture of their financial position — committed costs, anticipated costs, risk allowance, and programme interdependencies — with professional recommendations for managing their exposure | Example of a cost report that informed a specific client decision, particularly where the project was tracking above budget or where a programme change had commercial implications | Describing the production of cost reports without demonstrating the advisory service they supported |
| Measurement and Quantification | Demonstrating that measurement decisions are professional judgements with commercial consequences — not just the application of a standard method | Example of a measurement decision (provisional sums, risk items, CE assessment methodology) where your approach protected or improved the client's commercial position | Describing measurement processes or tools without connecting them to commercial outcomes |
| Change Management | Advising the client on the commercial implications of changes before they are instructed, managing the change process to protect the client's final account position, and advising on disputes arising from change | Example where you identified the downstream commercial risk of an instruction the client wanted to issue, or where your management of the change process produced a better final account position than would otherwise have been achieved | Describing the change control process without demonstrating professional judgement about commercial risk within it |
| Final Account | Advising the client on their contractual entitlements, the contractor's entitlements, the relative strength of disputed items, and the most commercially efficient resolution strategy | Example of a final account where your professional advice on the commercial strategy — not just the calculation — affected the settlement outcome | Describing the calculation of a final account without demonstrating advisory judgement about the settlement strategy |
| Construction Technology and Environmental Services | Advising the client or project team on how construction methods, materials, or building systems affect cost, programme, or commercial risk — demonstrating that technical knowledge informs professional advice, not just project description | Example where your understanding of a construction technology issue — a specification choice, a system performance problem, a material or method selection — directly informed a cost, procurement, or contract recommendation you gave to the client | Describing technical features of a project without connecting them to a professional recommendation or client decision — treating CTES as background context rather than a source of advisory content |
The Level 3 test — apply this to every example you prepare
Ask yourself: "If I had not been involved in this project, what would the client not have known — and what would have happened as a result?" If you can answer that question with a specific commercial consequence, you are at Level 3. If the honest answer is "things would have proceeded much the same way," you are describing process, not professional contribution.
NRM — Measurement Rules Quick Reference
| Document | Scope | Key professional use |
|---|---|---|
| NRM1 | Order of cost estimating and elemental cost planning — RIBA Stages 1–3 | Advising clients on budget establishment and design-stage cost risk. Professional judgement on risk and contingency allowances. |
| NRM2 | Detailed measurement — bills of quantities, specifications, and work schedules — RIBA Stage 4 and beyond | Tender documentation. Professional judgement on provisional sums, PC sums, and risk items. Basis for variation valuation under JCT. |
| NRM3 | Order of cost estimating for building maintenance works | Whole-life cost advice. Asset management and maintenance planning. Relevant for clients with ongoing asset responsibilities. |
Session 1 Answer Builder
Commercial Management and Commercial Risk
Complete and upload via the Session 1 booking form. Choose an example where your commercial risk identification or management made a demonstrable difference to the client's outcome.
Session 1 · Commercial Management
Commercial Risk Identification and Management
Session 1 scope
The NEC change management work from the AMEY highways renewal programme — particularly any example involving compensation event risk, Accepted Programme implications, or Disallowed Cost — is a strong vehicle. Alternatively, any project where your commercial vigilance prevented a cost overrun or dispute is appropriate. Choose the example where the professional contribution is most visible.
Opening Answer — READY Structure
R
Recognise the Problem
What commercial risk did you identify? Be specific — what was the risk, what was its potential quantum, and at what point in the project did you identify it? Name the project and contract context.
The risk should be one the client had not already identified without you — this is what makes it a professional contribution rather than routine monitoring.
E
Evaluate the Options
What were the options for managing the risk? What were the commercial consequences of each option? What did your evaluation of the options identify that was not immediately obvious?
A
Advise the Client
What specific advice did you give? What document or action did you prepare or recommend? How did your contractor background inform the quality of this advice?
D
Deliver the Outcome
What changed because of your advice? Quantify the commercial outcome where possible.
Y
Your Professional Responsibility
What would have happened if your professional contribution had not been made? This is the test — answer it honestly and specifically.
Anticipated Follow-Up Questions

If yes to all three, you are ready.
Session 2 · Cost Planning and Change Management
Cost Advisory, Change Control, and Final Account
Session 2 scope
Two examples are recommended for this session: (1) a cost planning example where your advice on an emerging design cost risk informed a specific client decision — the Manchester City Council project at an early RIBA stage if applicable; (2) a change management or final account example where your professional judgement on commercial strategy affected the settlement outcome.
Example A — Cost Planning Advisory
R
Recognise the Problem
What cost risk did you identify in the emerging design? At what RIBA stage? What was the cost driver and what was the gap between the design trajectory and the approved budget?
E
Evaluate the Options
What options did you present to the client? What were the cost, programme, and quality implications of each? What was the professional risk of not addressing the issue at this stage?
A
Advise the Client
What did you recommend and why? How did you present the recommendation — report format, verbal briefing, risk register update?
D & Y
Deliver / Your Responsibility
Outcome and your specific professional contribution…

R
Recognise the Problem
What was the change management or final account challenge? What was the commercial exposure and what was making it difficult to resolve?
E
Evaluate the Options
What were the options for managing or settling the position? What were the risks of each approach — including the risk of pursuing a strong contractual position versus the commercial value of early settlement?
A
Advise the Client
What was your professional recommendation on commercial strategy? How did you advise the client to approach the negotiation or settlement?
D & Y
Deliver / Your Responsibility
Outcome and your professional contribution to it…
Anticipated Follow-Up Questions — Session 2
Value Engineering
"How do you advise a client on value engineering without compromising the design quality or programme?"
Your answer — describe a structured approach to VE that goes beyond cost reduction to consider whole-life value and specification risk…
Disputed Variations
"How do you advise a client when a contractor claims an additional cost for work that the client believes is included in the contract?"
Your answer — cover your contractual analysis, how you advise on the strength of each party's position, and how you approach the commercial resolution…
Final Account Strategy
"When is it in the client's interest to settle a final account quickly, even at a premium?"
Your answer — demonstrate professional judgement about commercial strategy, not just contractual entitlement…
Session 2 readiness check
For Example A: Can you name the specific design decision that was driving the cost risk and explain why identifying it at that stage mattered? For Example B: Can you describe the commercial strategy you recommended — not just what happened, but why that was the right professional approach? If yes to both, you are ready.
Session 3 · Financial Control
Project Financial Control and Cost Reporting
Session 3 scope
Choose an example where your cost reporting gave the client more than a current cost figure — where you integrated programme information, risk analysis, and commercial intelligence to give them a complete picture of their financial exposure. This is the session where your dual contractor/consultant perspective is most valuable in explaining how you structure reports that reflect the commercial reality behind the contractor's reported position.
The Integrated Financial Picture
Before completing the READY answer, map out the financial control structure you used on your chosen project.
How did you structure the cost report? What categories did it include?
e.g. Approved budget / Committed costs / Anticipated costs / Contingency remaining / Risk register exposure / Forecast outturn cost
How did you integrate programme information into your financial control reporting?
What did your contractor experience allow you to read in the contractor's commercial position that the raw figures did not show?
Opening Answer — READY Structure
R
Recognise the Problem
What financial control challenge arose on the project? Was the project tracking above budget? Was there a programme-driven financial exposure the client had not recognised? Was the contractor's reported position inconsistent with the actual commercial picture? Name the project and describe the challenge specifically.
E
Evaluate the Options
What options did the client have for managing their financial position? What were the trade-offs — between cutting scope, accepting additional cost, restructuring the programme? What did your analysis of their position show?
A
Advise the Client
What professional advice did you give? How did you present the financial picture to the client — what format, what level of detail, what recommendations? How did you communicate uncertainty (risk allowances, contingency) without creating alarm?
D
Deliver the Outcome
What decision did the client make on the basis of your advice and what was the commercial outcome?
Y
Your Professional Responsibility
What was the professional consequence of giving the client this information at this point? What would have happened if the financial picture had only been revealed later?
Anticipated Follow-Up Questions — Session 3
Cash Flow Forecasting
"How do you produce a cash flow forecast and how do you use it to advise the client?"
Your answer — go beyond describing the S-curve. Explain what the cash flow told the client about their funding exposure and how you used it to help them manage their financial relationship with funders or internal finance…
Reading the Contractor's Position
"How do you assess whether a contractor's commercial position as reported to you reflects the actual financial reality of the project?"
Your answer — draw explicitly on your contractor background here. What do you look for? What are the signals that a contractor's reported position is not reflecting the real commercial picture?…
Delivering Bad News
"Describe a situation where you had to tell a client the project was significantly over budget. How did you approach that conversation professionally?"
Your answer — demonstrate professional composure and client focus. The answer should show how you gave the message clearly, with the evidence to support it, and with constructive options rather than just a problem statement…
Session 3 readiness check
Can you describe the structure of your financial control reporting and explain why each element is there? Can you explain specifically how your contractor experience informs how you read a contractor's commercial position? Can you describe a situation where you gave a client difficult financial advice and explain how you approached it professionally? If yes to all three, you are ready.
Session 4 · Construction Technology and Environmental Services
Construction Technology and Environmental Services
Session 4 scope
Select an example where your knowledge of construction methods, materials, or building systems was the basis for a professional recommendation — not simply background context. Strong examples include: a specification decision with cost or performance implications you advised on; a construction method that affected programme and commercial risk; a building services or environmental system where the QS input shaped the client's decision. Your contractor site experience is a significant asset here — draw on it.
Opening Answer — READY Structure
R
Recognise the Problem
What construction technology or environmental services issue arose on the project? What was the technical question and why did it have commercial or professional significance? Name the project and describe the context specifically — the construction method, system, or specification that was in question.
This competency is not about describing what was built. It is about showing that your technical knowledge informed a professional decision. Start from the technical problem, not the project description.
E
Evaluate the Options
What were the technical options available? What were the cost, programme, performance, and risk implications of each? Where did your knowledge of construction technology allow you to identify a risk or opportunity that was not immediately apparent from the design documentation alone?
A
Advise the Client or Project Team
What professional recommendation did you make? Was it a cost plan adjustment, a procurement strategy change, a specification comment, a risk allowance revision, or a contractual provision? How did your technical understanding inform the advice you gave?
The advice must be yours — not the structural engineer's or the M&E consultant's recommendation that you passed on. Show where your professional judgement, informed by your technical knowledge, contributed something the design team alone would not have provided.
D
Deliver the Outcome
What decision was made on the basis of your advice? What was the commercial or technical outcome? Quantify where possible.
Y
Your Professional Responsibility
What would the client have missed if you had not identified and advised on this issue? How did your dual contractor/consultant background affect the quality of the technical advice you were able to give?
Anticipated Follow-Up Questions — Session 4
Technical Knowledge Depth
"How do you keep your construction technology knowledge current given that your primary role is commercial rather than technical?"
Your answer — describe specific CPD, site visits, industry publications, or professional engagement that keeps your technical knowledge live. Reference a specific example of a technology or system you have developed knowledge of recently…
Specification and Cost Risk
"How do you advise a client when a preferred specification has a significant cost premium over an equivalent alternative?"
Your answer — demonstrate a structured approach that considers whole-life cost, performance risk, procurement implications, and the client's specific brief and priorities…
Interface with Design Team
"What is the QS's role in relation to construction technology decisions — and where does that role end and the engineer's or architect's begin?"
Your answer — demonstrate clear professional boundaries. The QS's role is to translate technical decisions into cost and commercial consequences, advise on procurement and contractual implications, and ensure the client's financial exposure is understood. Avoid claiming technical design authority…
Environmental Services
"How has your awareness of environmental or building services systems informed your commercial advice on a project?"
Your answer — describe a specific project where M&E systems, energy performance, or environmental services had cost or procurement implications you advised on — e.g. whole-life cost, specialist subcontractor procurement strategy, performance specification risk…
Session 4 readiness check
Can you describe a specific technical issue — not a project description — where your knowledge of construction technology was the basis of a professional recommendation? Can you explain where the QS's advisory role in relation to technical matters begins and ends? Can you describe how your contractor background gives you a technical perspective that informs your commercial advice? If yes to all three, you are ready.
