Competency Q&A Flashcards
You talk about the contractor ceasing trading on the Arts Council of England project, can you talk me through the value engineering options provided by the contractor and the process you followed?
- A Value Engineering workshop was held which was contractor led.
- 3 alternative doors than the originally specified tulip door were presented. These work
- American oak
- tulip door from other suppliers
- Timber door with a tulip veneer to match existing - Upon review on time, cost and quality implications, i summarised them within a report with a recommendation to the client.
Can you talk me through the phases of a value engineering process?
- Information Phase
- Speculation Phase
- Evaluation Phase
- Development Phase
- Presentation Phase
Can you elaborate on the VE processes?
- Information Phase is understanding the clients objectives around value
- Speculation Phase is listing creative ideas with a lesser capital which are more efficient
- Evaluation Phase - Ideas from the speculation phase are more defined such as what cost / programme savings they offer and the other ones are discarded
- Development Phase is where the ideas retained from the Evaluation Phase are expanded into workable solutions
- Presentation Phase is what you present to your client and the justifications
What option did you present to the Arts Council of England client regarding the value engineered door and why?
I recommended the Timber Door with a tulip veneer as the prime objective was for aesthetics and due the the programme and cost implications, this door was cheaper and quicker than the alternatives provided
What two options did you evaluate for the external works and public realm on Bury College Histem?
It was a cost benefit analysis I undertook for a landscape architect to assist in determining a level of specification for the client on 2 landscaping proposals, soft heavy and hard heavy.
Can you tell me types of soft / hard landscaping used on bury college Histem?
Both proposals had a mixture of hard and soft landscaping however, one with more hard landscaping and the other with more soft landscaping.
The hard landscaping included items such as decking, imprinted driveways and rubber walkways
The soft landscaping included items such as grass, shrubs, hedges and trees.
From the cost benefit analysis on bury college Histem landscaping works, what was more expensive?
The soft landscaping was more expensive as the vegetations and shrubbery chosen was ornate.
I also advised that this would add increased costs to the maintenance
You mention on Wythenshawe hospital, you explored obscure materials, can you elaborate?
I explored materials such as Altro Whiterock cladding and anti slip clinical vinyl flooring as these were proven to be hygienic and easy to clean.
Other items which were explored were bumper rails and corner protection.
What we’re the different types of canopies you compared on North Chadderton Highschool?
They were both types of a monopitch canopy, one which was galvanised and the other powder coated.
The structural arrangements were different with one having a better provision for lighting.
What is galvanising?
A finish to construction materials by applying zinc onto a surface for protection.
What is powder coating?
A durable factory applied coating on metals which is available in many colours.
It is sprayed on.
What are the different types of cladding systems?
- Stick systems
- Mullions and glass or opaque panels connected piece by piece
- Allow for integration with other systems such as sliding doors / windows
- more time to instal due to sealing issues - Panellised systems
- constructed in factory to improve quality control and speed of erection
- connected to structural columns or floor slabs - Unitised system
- narrow width panels pre assembled under factory conditions
- craned into positions with brackets to attach to floor slab or frame
- higher direct costs but reduced install costs
What are types of cladding?
- Rainscreen cladding
2. ACM cladding
Describe a rainscreen cladding detail?
- Provides a high screening function rather than enclosure in its own right
- Used to shield a wall
- Design to permit some controlled leakage with main function to resist air and water to the wall behind
What is ACM cladding?
Aluminium composite material
Consists of 2 skins of aluminium bonded to either side of a lightweight core or material such as polyethylene or a mineral core aimed to provide insulating properties
What is the significance of ACM in relation the Grenfell?
The ACM cladding in use was though to contain combustible materials that contributed towards the spread of fire across the external elevation of the building.
As a result, the UK government has now banned the use of combustible materials on high rise homes from 29th November 2018
The ban means that combustible materials are not permitted on the external walls of new buildings above 18m.
Local authorities need also need to undertake remediation works to replace dangerous ACM cladding on existing buildings.
Following the Grenfell Disaster are you aware of any guidance the RICS has published to support fire safety?
I am aware that the RICS has published the Guidance Note ‘Cladding for Surveyors 1st Edition March 2021’ to support surveyors working on Multi-Storey and multi occupancy residential buildings.
The document aims to improve surveyors knowledge of external wall cladding systems that may be considered within the external wall fire review.
What is an EWS1?
An external wall system fire review certificate
It is applicable for a multi storey residential property to be bought, sold or re-mortgaged.
What is the new fire safety act 2021?
It was introduced in March 2020 and holds significant legal obligations of organisations deemed to be responsible persons.
It is an update from the fire safety order 2005.
It is an update to clarify that it will apply to any external envelope elements
Forces owners, landlords and managing agents of multi-occupied residential buildings to take precautions to identify dangerous cladding and remediate them
What are the stages of the RIBA Plan of Work?
0 - Strategic Definition 1 - Preparation and Brief 2 - Concept Design 3 - Spatial Coordination 4 - Technical Design 5 - Manufacturing and Construction 6 - Handover 7 - Use
What are types of construction methods?
- Top Down Construction
2. Bottom Up Construction
What is Topdown Construction?
- “Top down” is used to speed up the construction process of a building with basement levels.
- The ground floor slab is cast with an access hatch.
- The ground below is excavated and another slab is formed. If there is another level, the process is repeated. Piles are usually used as foundations and also act as retaining walls. It allows the building above to be constructed at the same time as the basement.
What is Bottom Up Construction?
- “Bottom up” forms the basement and then works upwards in a traditional manner. This offers a simpler construction than top down methods of construction but will often carry a longer programme duration.
What are the elements in a construction project?
Substructure
- Excavation
- Disposal
- Foundations
Superstructure
- Frame
- Upper Floors
- External Walls
- Roof
- Internal Finishes
- Services
- External Works
What is lean construction?
It is a process to maximise value and minimise waste
What are the principles of lean construction?
- Value
- Value Stream
- Flow
- Pull
- Perfection
What are Life Cycle Costs?
The costs that will be incurred over a defined period of operating and maintaining a building or an asset including repair, maintenance, replacement, cleaning, decorating, services provision and disposal.
What are the advantages of Life Cycle Costs?
- Allows for consideration of the long term implications of a decision
- Enables informed decision to be made on material selection
- Can result in lower operational, maintenance and replacement costs
- Used to plan future maintenance requirements
What are the disadvantages of life cycle costs?
- Future costs are optional and the costs of maintenance can always be deferred
- Components are not always replaced due to end of life which is possible to determine at design stage
- The cost of defects, bad workmanship and design faults cannot be predicted
- It is hard to predict life spans, inflation and maintenance requirements over long periods
What should be considered in life cycle costs?
- Capital Costs
- Operational Costs
- Maintenance Costs
- Replacement Costs
- Disposal Costs
Why would you take out insurance options in joint names?
- Where the employer and the contractor are insured under the same policy.
- It stops the insurer having the right of subrogation against the other party if they caused the loss
You have acted as a CA / EA in your experience, can you tell me the difference?
A CA is a Contract Administrator under a traditional form of JCT Contract
An EA is an Employer’s Agent under the JCT Design & Build Contract.
Both are to act impartial under the contract.
Can you talk me through a payment certificate and when you would issue one?
Under a JCT Traditional Contract, a interim payment certificate is to be issued no later than 5 days from the due date.
Under a JCT Design & Build, a payment notice is to be issued no later than 5 days from the due date.
An interim certificate or notice consists of
- key project, employer and client references
- the gross and net amount to be paid as recommended by the Quantity Surveyor
- the timescales of payment to be made
What are the payment dates under the JCT Contract?
If it is a traditional JCT form of Contract
7 days after the Valuation Date is the Due Date
14 Days after the Due Date is the Final Date for Payment
Not less than 5 days before the final date for payment a pay less notice should be issued
Under a JCT D&B Contract, if the Contractor does not submit his application, what happens?
Under a D&B, it is a contract led payment therefore, the dates would start from when the application is received by the employer
Can you talk me through the change control procedure applied in the Arts Council of England Project?
All client or contractor changes were tracked on a change control spreadsheet which included:
- The reason for change
- Who requested the change
- The consequences of the change in regards to time, cost, quality and H&S
- The risks associated with the change
- Alternatives to the proposed change
- Time by which the change should be instructed
Why would you issue a pay less notice?
A pay less notice is issued to a Contractor not later than 5 days before the final date for payment stipulating reasons as to why he will not be paid a sum of money.
This is usually after the payment notice has been issued and a loss and expense or outstanding information required has not been given between the payment notice and final date for payment period.
You state that on the ITV Camera Store project, the contractor failed to achieve the installation date set in the contract. Why did you provide the options that you did to the client?
Well under the contract, the Employer would be able to levy damages per week for the contractor not completing on the specified date.
However, to avoid destroying a good pre-existing relationship that the client had with the contractor, I advised that they could adjust the completion date due to the requirement of a police escort for the delivery of the modular unit.
You state that the new adjusted completion date was not met on the ITV camera store project, can you talk me through the process of what you did?
I advised the client and issued a non completion certificate which triggered the liquidated damages mechanism.
What would constitute to an extension of time under the JCT Contract?
Under the JCT an extension of time can be requested for under a Relevant Event. Examples are:
- Variations
- Instructions
- Deferment of possession
- Suspension by the Contractor for non payment
- the carrying out of work by statutory authorities
- Exceptionally adverse weather conditions
- Force Majeure
Can you talk me through some of the key contractual mechanisms in a JCT contract?

- Practical Completion
- Relevant Events
- Relevant Matters
- Novation
What are the main provisions under the JCT contract?

- Settlement of disputes
What is the format and structure of a JCT Contract?
- Articles of Agreement
- Contract Particulars
- Conditions of the Contract
- Schedules
What is novation?
Contractual rights and obligations are transferred from one party to another
If there are problems with the design, after novation of the architect, will go would be responsible?
At the point of novation, the client would agree the level of design that was satisfactory and would be signed off by all parties
The contractor would then become responsible for the architect and his design should any problems arise during construction
Disputes can arise from this due to the transfer of services
Can you tell me the difference between novation and assignment?
Novation is a mechanism where one party can transfer obligations under a contract and all benefits arising from that to a third party.
Assignment is where contractual benefits are assigned however contractual burdens cannot be transferred
What is set off?
Money owed to the employer by the contractor which are deducted against payment due to the contractor
Describe the differences between statutory provisions and contract provisions?
Statutory provisions are set out by law and must be complied with
Contract provisions relate to the contract in question and project specifics
After a valuation and certificate are issued, the client advised that they don’t have sufficient funding to make the payment. What would you do?
The client is contractually obliged to honor payment once the certificate has been issued.
In this situation, I would contact the client and contract asap to arrange some sort of payment.
Failing to do this, the contractor would need to find additional finance to honor payment
What is the difference between NEC and JCT?
It’s usage
NEC can be used within the building and civil engineering projects whereas JCT specifically only for building projects
NEC can be adopted to a number of bespoke contract strategies due to the various options available whereas JCT has standard set clauses
How is contract under hand different from a deed?
A deed is signed by a witness and traditional authenticated by a seal
The limitation period for under hand is 6 years and deed is 12 years

What is a defined provisional sum?
An allowance included within the contract sum for certain specified information that can be given about the works and the contractor can programme and allow for preliminaries
What is an undefined provisional sum?
An allowance included in the contract sum for work which has minimal information and the contractor cannot programme for it
What are the main suites of construction contracts?
- JCT
- NEC 3 & 4
- FIDIC
- ICE
- ECC
How many sections are the conditions in the JCT Contract divided into?

What are the advantages NEC and JCT?
JCT Advantages:
- Industry Standard
- cover most forms of procurement
- comprehensive in detail and considered to be fair
NEC advantages:
- Applicable to a variety of procurement strategies
- Simple language is used
- Act as a stimulus for good management
What are the disadvantages of NEC and JCT?
JCT Disadvantages:
- long and unnecessarily complex
- they are sometimes thought to compromise conditions to satisfy all parties
NEC Disadvantages:
- Often considered to be used for civil engineering projects or partnerships
- Limited exposure on the market so not fully tried and tested with case law
What are the key differences between NEC and JCT?
- NEC is concise and written in plain English
- NEC has optional clauses reducing the need to amend contracts like JCT
- Provisions of early warning procedures encourage a proactive approach in NEC
- NEC has compensation events which deal with both money and time
- There is not QS or EA in NEC, only a project manager who takes on both roles
What is a compensation event?
Events that entitle the contractor to be compensated on programme and cost if the contractor is not at fault
There are 19 compensation events listed in clause 60.1
What are early warning notices under an NEC contract and what’s their purpose?
Notices given by the PM or contractor of any matter than could potentially have an impact on time, cost or quality.
What are some types of teams?
- Office teams
- Project teams
- Design teams
What are some examples of team working you have demonstrated?
I have engaged with building surveyors and M&E specialists and harnessed their knowledge and expertise when I don’t understand technical aspects of a project.
What is the aim of diversity and inclusion steering groups?
It’s a group which supports and encourages underrepresented groups into construction. I have personally been involved in undertaking talks about Quantity Surveying to schools, colleges and university’s.
What is workplace diversity?
The acceptance and inclusion of employees of all backgrounds, acknowledging that everyone has a strength they can provide
What are some advantages of a diverse team?
- Increased productivity
- Increased creativity
- Improved cultural awareness
- A positive reputation
On bury college external works, you advised the client on the most cost effective solution. Why was the chosen option more cost effective that the others?
Because the hardscaping would provide alleviate the need for regular maintenance, irrigation and replacement whereas the hardscaping was more hard wearing
On the arts council project, you advised the client following a door comparison exercise. What we’re the cost and quality benefits of the chosen product over the others?
- American oak
- most expensive
- Highest quality
- quick lead time - Tulip door from other suppliers
- cheapest option
- low quality
- difficult to match existing and varnish
- long lead time - Timber door with a tulip veneer to match existing
- medium cost
- good quality for clients purpose
- quick lead time
And how did you ensure the quality of the new product on the arts council of England scheme was similar to the original door specification?
Obtained samples from the supplier for the client and architect.
Once the client was happy, the architect signed them off.
You took part in a VE meeting to discuss soundproofing meeting rooms. What methods were proposed to achieve the soundproofing requirements?
Yes to try and achieve a Speech Privacy Level of 75, the architect explored:
- 45 DB Sound Proof Insulation
- Double layered acoustic plasterboard
- Sound deflectors / sound proofing panels as a design
- Sound attenuator through the HVAC system
What needed up being the most cost effective / value engineered solution on sound proofing?
As the clients requirement was not a fully sound proofed meeting room, just to muffle noise, double layered sound proof board was the best and most cost effective solution.
