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
