Q

Explain continuous flight auger piles?

A

Continuous Flight Auger (CFA) piles are a deep foundation method where a hollow-stem auger is rotated into the ground, removing soil and then pumping concrete through the hollow stem as the auger is withdrawn.

A

Durable
Versatile - can be formed in any shape
Sound insulation
Fireproofing

22
Q

Disadvantages of concrete frame?

Study These Flashcards
A

Weight
Inflexible once cast
Bad for the environment

23
Q

Advantages of timber frame?

Study These Flashcards
A

Speed of construction
Sustainable
Design flexibility
Cost

24
Q

Disadvantages of timber frame?

Study These Flashcards
A

Limited height
Subject to infestation and rot
needs treating regularly
Not fire resistant

25
Advantages of Steel Frame?
Fast Construction time Can be used for tall buildings Light in weight Can span open spaces
26
Disadvantages of Steel Frame?
Expensive (but costs can fluctuate and erection speed and lead to prelims savings) Not fire resistant unless treated Corrosion Cannot be adapted during erection
27
Elaborate on your understanding of modern methods of construction. Particularly modular construction?
Modular construction is a method of construction modular pods off site in factory conditions and then transporting them to site and assembling them together This allows for faster construction, consistent quality and less waste
28
Name some modern methods of construction?
Panellised units volumetric construction SIPs (Structural Insulated Panels) CLT
29
Economic advantages of Modular Construction?
Reduced labour costs minimised waste production Faster construction times (reduced prelims)
30
Advantages of Modular Construction?
Cost Effective (if there are large quantities of the same unit) Programme Lower Environmental Impact (less waste) High Quality Control
31
Disadvantages of Modular Construction?
Early Planning Transportation Challenges Limited Design flexibility
32
What was the foundation type proposed with modular construction on Arkwright?
Strip / Pad Foundations
33
What is typically involved in the process of manufacturing volumetric modular pods?
The process of manufacturing volumetric pods offsite in a factory setting. This includes the creation of the individual modules installation of essential utilities like electricity, and plumbing, exterior and interior finishings, and quality inspections
34
Elleray Hall - What were the reasons for advising aluminium windows would be suitable?
Aluminium windows provide: - affordable and low life cycle costs - durability - aesthetically pleasing, powder coated in any colour - aluminium is 100% recyclable
35
Elleray Hall - Advise me on the environmental qualities of the 3 window types. Which was the most environmentally friendly and why?
36
Name different window options and theirs pros and cons.
Other options that I considered included: -uPVC windows cheaper than aluminium windows, low maintenance sustainable because they don't attract heat or lose warmth and can be recycled. However they do not look as good as aluminium windows so were unlikely to be acceptable. - Steel windows are strong, durable and can also be aesthetically pleasing. However, they are more expensive than aluminium windows so would not have been suitable for this project. -Timber windows provide a traditional look with good aesthetics for this project. They are also the most sustainable of these window options. However, they can be expensive and require maintenance to reduce the chances of rotting and warping which they are susceptible to.
37
In your competencies, you discuss modular and panelised construction methods. Can you tell me the difference between SIPS and CLT panels.
SIPs is Structural Insulated Panels (OSB board with insulation sandwiched in between) CLT is Cross Laminated Timber (Solid timber with good thermal and acoustic properties and fire resistance)
38
You discuss the affordability and life cycle cost of aluminium windows. What is NPV and how is it used to compare costs over their lifecycle.
‘Net Present Value’ (NPV) represents the difference between the present value of cash inflows and the present value of cash outflows for an investment, where the future costs have been discounted to adjust them to present values.
39
What is the fundamental difference between end bearing and friction piles
End bearing piles are where ground conditions lower down are strong enough to take the load Friction is where the good ground conditions are too low to get to so the whole of the pile is used to transfer load to the surround soil, through friction or adhesion.
40
Can you describe for me three examples of sustainable heating or cooling technologies
PVs, ground source Heat Pumps, ground source heat pumps, Heat Recovery
41
Can you give me examples of water conservation technology
Harvesting, green/blue roof
42
What was the cost difference between aluminium windows and upvc?
PVC (uPVC) 100% Aluminium 120% – 150% Timber 140% – 180% Steel 200% – 400%+
43
Elleray - How did you work out the life cycle costs for the aluminium windows?
I did not work out life cycle costs but I am aware that aluminium has low to medium purchase cost, low maintenance costs and can be relatively energy efficient with thermal breaks installed.
44
What other flooring types were considered other than tiling on Arkwright?
Vinyl and laminate flooring were considered but discarded as their lifespans (10-25 years) are shorter than kitchen tiles
45
What is the lifespan of kitchen flooring tiling?
50-60 years
46
Two types of defects
Patent - Easily visible Latent - Not visible could happen during rectification period
47
What is the lifespan on aluminium windows?
50 years
48
What is the lifespan on uPVC windows?
25-30 years
49
What are SUDs?
Sustainable Drainage Systems - drainage methods that manage surface water runoff in a more natural and sustainable way than conventional drainage systems, such as pipes and tanks.
50
What is an EAF in terms of steel making?
An electric arc furnace (EAF) is a furnace that heats material by means of an electric arc. Uses less energy than typical furnaces
51
Arkwright Garages - What are the works packages of the building that would not be included in the modular works package?
Foundations, External works Below ground drainage External services
