Welcome to your site ELECTRICAL LEARNING , I present to you in this topic a wonderful book about Electric Wiring Domestic Tenth Edition .
There are two general aspects of the development of buildings:
n conventional or traditional methods;
n modern or industrialized methods.
Conventional or traditional methods are studied within the first two years of most
construction courses, with the intention of forming a sound knowledge domain
before proceeding to studies of advanced techniques within the final years.
There is, nevertheless, a component of continuity and overlap between traditional and
contemporary, and both are frequently deployed on an equivalent building, e.g.
traditional brick facing to a prefabricated steel-framed commercial building or
to a factory-made timber-framed house.
Initial studies of building construction consider the smaller sort of
structure, like a domestic dwelling of 1 or two stories built by labor-
intensive traditional methods. Generally, it’s more economical to construct this
type of building by these methods, unless large numbers of comparable units are
required on an equivalent site. In these circumstances, economies of scale may justify
factory-manufactured, prefabricated elements of the structure.
These industrialized methods are usually a rationalized manufacturing process wont to produce complete elements, i.e. floors, walls, roof frames, etc.
In modules or standardized dimensional increments of 300 mm.
Very few building contractors within the UK and other developed countries employ
many staff directly.
They are therefore relatively small companies in comparison
with the capital value of the work they undertake.
This is partly thanks to the variable
economic fortunes of the development industry and therefore the need for flexibility.
