Mock Interview (DeLever) - Competencies Flashcards
Building Pathology
Goole - What were your recommendations?
To carry out a hammer test to all the balconies to establish the extent. I advised for repairs where required and to minimise the on-going issue, apply an anti-carbonation paint to the balconies. I also provided the client with costs.
Building Pathology
Goole - How were the repairs undertaken; what was the process?
- Remove the spalled concrete
- Clean the exposed steel reinforcement
- Apply anti-corrosion oxide primer
- Install polymer modified repairs mortar (Sika Top)
- Consulted with Sika for advice on the concrete repairs
Building Pathology
Withernsea - How did you come to the conclusion it was sulphate attack?
I noted the floor was doming centrally. There was map pattern cracking to the slab. I also noticed there was vertical cracking to the brickwork externally below DPC to the corners of the property. The bricks were pushing outward by 3-4mm.
Building Pathology
Withernsea - What causes sulphate attack?
When present sulphates become soluble they travel interstitially into the concrete where a chemical reaction occurs between the sulphate ions with calcium hydroxide and calcium aluminate hydrate to form gypsum and ettringite. The ettringite causes the expansion of the concrete.
Construction Technology
Market Weighton - Can you talk me through the problem?
Upon inspection I noted severe vertical cracking to the boundary retaining brick wall. The wall was constructed off a concrete plinth and there was slippage approximately 450mm high from ground level. There were no weep holes and no expansion joints. I identified the bricks to be calcium silicate.
Construction Technology
Market Weighton - What works were required?
I gave the client three options following the removal of the brick wall:
- Engineered brick wall with weep holes and expansion joints
- Reinforced concrete wall
- Gabion Stone Basket Walling (Cheaper, short programme, sustainable)
Construction Technology
Market Weighton - Why were the gabion baskets the best option?
- Cheaper
- Short programme
- No wet trades involved
- Sustainable and could also be sourced locally
Construction Technology
Woodmansey - Explain to me what the thermal improvements were to the main hall?
The main hall was a pitched roof with a suspended ceiling. The clients brief was to remove the suspended ceiling a restore natural character.
Construction Technology
Woodmansey - How was the warm pitched roof achieved?
Installed a timber batten to the underside of the rafter for more depth to install 50mm insulation between the rafter with 50mm ventilation gap between the underside of the roofing membrane and the top of the insulation.
I then installed 57.5mm K118 Kooltherm insulation a plasterboard system across the rafters to minimise thermal bridging.
Contract Admin
Leconfield Primary School - Why did you use 90% price 10% quality?
I included a price element because we are a local authority and price does matter.
The quality element was due to the specialist work required which was the timber frame structure and new heating system.
Contract Admin
What was the quality part?
The quality was marked on the Programme, Method Statement and Employment Skills Plan
Contract Admin
Leconfield - Talk me through the process of agreeing the final account?
The final account was easy to agree. Because I used the NEC3 there is an early warning mechanism there, CE’s are done from quotation so when receiving the contractors draft final account there wasn’t really any discrepancy on there so agreeing the final account was quite straight forward.
Contract Admin
Burton Pidsea - You advised the client on the NEC3 Short Form; why did you advise this contract for this scheme?
I advised the client to use the NEC3 Short Contract on the basis that the NEC promotes collaborative approach and I feel you have greater cost certainty using the NEC3 Contract.
Contract Admin
Roos - Talk me through the process of an interim payment?
Having received the application for interim payment from the contractor I would assess the work the contractor is claiming for against the work completed to date. Should the contractor be found claiming for incomplete work, I would submit a pay less notice to the contractor.
Contract Admin
Roos - What time scales are you working towards for delivering the interim payments?
28 days for interim payments.
Contract Admin
Roos - Do you know what the due date is?
Last working day of the month
Design & Specification
Hallgate - Explain to me what some of those recommendations were?
It was a relatively small room which was used for storage by the school. The school wanted the space to be turned into a disabled toilet and storage room. I provided the school with a couple of designs and costs.
Design & Specification
Hallgate - what designs did you provide to the school?
One of the designs the school wanted a shower, disabled toilet, changing bed, storage space. I told the school this option would not be suitable because we would not be able to achieve the spatial requirement for the Doc M package.
I then produced an alternative design for the school, omitting the changing bed and shower room.
Design & Specification
Hallgate - Which building bulletin did you refer to; what does it cover?
Building Bulletin 103 covers non-statutory area guidelines specific for school buildings both internally and externally.
Building Bulletin 93 - acoustic guidelines
Building Bulletin 100 - design guide for fire safety in schools
Design & Specification
You mentioned fire regulations; what sort of guidance were you using in that regard?
Approved Document B Volume 2,
Building Bulletin 100
BS 9999 - provides recommendations and guidance on the provision of measures to control or mitigate the effects of fire, including business continuity and the environment
Fire Safety
What sort of things does the Fire Regulatory Safety Order 2005 impose on people?
It provides a framework for regulating fire safety in all non-domestic premises including workplaces and the parts of multi-occupied residential buildings (Covers England and Wales)
It places a requirement on any person who has some level of control in premises to take reasonable steps to reduce the risk office and make sure people can escape safely if there is one.
The order applies to virtually all premises regardless of whether they are permanent or temporary buildings.
It does not apply to privately owned buildings including individual flats.
Fire Safety
Who are the duty holders under the legislation?
If you have control of the premises:
- Business owner
- Employer
- Landlord
Whoever maintains control of the property, you are the ‘Responsible Person’ and are ultimately accountable for the fire safety of that premises and the individuals within it.
Fire Safety
Think about your school, who would be responsible?
In a school it’s the headteacher. They may delegate it to a member of staff but ultimately it’s still his responsibility.
Fire Safety
What sort of frequency does a FRA need to be undertaken?
- Every 4 years and reviewed every 12 months
Recommend a new FRA following major work.
