2. Compare your diagrams in pairs.
Activity 5 Discuss the following questions.
1.In the extract from the “The Stars Shine Down” the author describes the process of building a house in the USA in 1980s.
Is this description similar to the process of construction in Russia nowadays?
Do we use the same equipment? Is the sequence of construction stages the same or different? In what way?
How long does it take to put up a building?
2.Have you ever watched a building being constructed?
Lara is very enthusiastic to be involved in the construction activities: “Every morning and every evening she went downtown and stared at what was being built. I own this, Lara thought. This
11
belongs to me.” Do you agree that the process of turning design into reality is really exciting? Why?

Prefabricated buildings |
Unit 2 |
|
|
|
Lead in In unit 1 you have learnt about the construction of a building in brief. Now we are going to study the assembly sequence of a prefabricated building in detail.
1.Can you give a definition of a prefabricated building? How does the meaning of the prefix prehelp you understand the meaning of the word?
2.Compare your definition with the one given by the supplying company Construction Guide (http://www.construction-guide.com/index.htm)
Prefabricated buildings are buildings which are pre-cut, pre-drilled, and pre-engineered before the actual building is constructed. The prefabrication process sometimes takes place in one place under one roof, and other times the parts are made at different locations and then shipped to the construction site.
In the past, prefabricated buildings were reserved for industrial structures, but today's architects are also building prefab homes in large-scale projects. Prefab structures are not a new idea. Rather, they have been around since at least the 1930s and 1940s. Prefabricated buildings have been popular for two reasons -speed of construction and relative cost.
3.Explain the meaning of the italicises words. What other words with the prefix precan you remember?
What made prefabricated buildings popular in Europe? Are they popular in Russia?
1. In the pictures below you can see three major types of prefabricated buildings:

Match each of the types with their pictures.

IIf you need a permanent structure, you'll be choosing between steel buildings and modular buildings. Both are "alternative" construction methods, as opposed to traditional ground-up construction. Here are some of the important distinctions:
IIPrefab Building Construction
Up to 90% of the work in creating a modular building is done at the factory, including both the interior and exterior: walls, roof, doors, wiring, carpeting,
18
and more. They're built using standard construction materials like lumber and drywall. The mostly-finished building is then delivered and installed at your site.
In contrast to the modular building process, only the components of steel buildings are fabricated at the factory. Steel beams, sheeting, and fasteners are delivered to your site, and the building is pieced together on site. Any interior work is done after the construction is complete.
Because of the specific skills needed to assemble modular buildings, you'll need a specialized contractor to do your on-site work. Steel buildings are delivered with detailed blueprints and require only general construction skills to assemble - any qualified general contractor should be able to handle the job.
Both modular and steel prefab buildings shorten construction times over traditional buildings. Modular buildings require much less work to be done on site but take longer for the factory to produce. From initial order to completion, total construction times for these structures can be fairly similar. However steel buildings are often simpler structures with less finishing work; in practice they tend to take less time.

|
Modular buildings can also be put on top of each other to create buildings up |
|
to 3 or 4 stories high. |
|
Steel buildings can be as small as 10' x 20' or as large as 150' wide by nearly |
|
unlimited length with no interior columns. To get over 150' wide, steel |
|
buildings require interior columns at regular intervals. |

Prefab Building Customization |
|
Modular buildings generally offer more flexibility in design than steel |
|
buildings. With steel buildings, you choose the size, location of doors and |
|
windows, and pitch of the roof, but the building itself is just a box. Modular |
|
buildings provide more flexibility for customization, which can be important |
|
if you need a particular layout. Additionally, modular buildings typically |
|
come with finished interiors - steel buildings may include interior wall panels. |
VCost
Modular buildings can range from $35 to $100 per square foot. The range is so large because the price includes finishing: a basic classroom or office will usually fall on the low end of that scale, while a fancy retail outlet with lots of customization will be more expensive.
Steel buildings are less expensive, often because they are less finished on the inside. Very basic steel buildings can be put up for as little as $16 to $20 per square foot. More finished metal buildings are usually $20 to $30 per square foot, and extensively customized buildings with brick facades, unusual shapes, or complicated construction can reach $40.
VI Aesthetics
Both steel and modular buildings have improved appearances in recent years. Modular buildings can be constructed with wood, steel, brick, or stucco exteriors, and steel buildings can add facades using the same materials. However, if the appearance of your buildings is important, modular buildings provide more flexibility at a lower cost than steel.
VII Office trailers
You should also consider if an office trailer is all you need. Office trailers - also known as mobile offices - are the cheapest and most temporary type of pre-manufactured building. They range in size from 8' x 20' to 12' x 60' (a "singlewide") and can be combined into double, triple, or larger groups.
