What are Safe Construction

Practices? Imperatives for Safe Construction

Do¶s and Don¶ts

Elements For Promoting Safer Building

Earthquakes

Floods



Safe construction practices are

those practices which should be

followed in disaster prone areas

while constructing houses or any

type of buildings so as to avoid somuch damage at the time of a

disaster.



Reduction in huge loss of time element in planning,design, reconstruction phase lasting from 1 to 5 yrs or more

Saving of limited, costly and scarce resources of

building materials and money (finances) for the loss of

buildings, properties and infrastructure;

Reduction in economic loss to the community /

nation(s) due to its negative impact on

economic/industrial activity and social and welfare areas

like health, education and community well being;



Equally important ar e the very usef ul pictorial brochur es ( f ol ders),

which i denti f i es the wrong construction featur es, which ar e not to be

utilised and which had contribut ed to d amage and destruction and at

the same time i nd icat e the ri g ht construction featur es, which ar ed isast er r esistant. These have been ev ol ved f or earthquak e r esistant

construction, cyclone r esistant construction, f lood prot ect ed

construction and ar e ex tr emely usef ul i n pictorial and g raphical

f orms, which can also be utilised by semi-lit erat es. The details ar e

av ailabl e f or all el ements of construction. These ar e normally

prov i ded i n local ver nacular lang uages with very limit ed pri nt ed

t ex tual f orm but with mor e g raphical (pictorial) f orm. These ar e

pri nt ed and circulat ed very wi dely and f r eely. Further, wall post ers of

the same ar e also d isplay ed i n many public off ic es, off ic e buil d i ng s

and public asset buil d i ng s wher e common peopl e have acc ess.



The features to be considered at the stage of

architectural planning and structural design of buildings for protection against earthquakes are:

Building configuration

Foundation Control on openings in walls

Reinforced concrete bands in masonry buildings.

Vertical reinforcement.



Foundation of an earthquake-resistant building:

a) Assess the potential for soil liquefaction toavoid tilting cracking and failure of structure.

b) Adequate foundation design should be

planned so that building can withstand

earthquakes. The damaging effects of earthquakes on the

ground are

a) Soil failures such as liquefaction and

landslides caused by shaking.b) Tidal waves (Tsunami) i.e. large waves on the

surface of water bodies, that can cause major

damage to shoreline areas.



Protection measures against floods are:i) Residing on river banks and slopes on river banksshould be avoided.ii) Buildings should be built at 250 metres away fromthe sea coast/river banks.iii) To build proper drainage system in all flood prone

areas.iv) To construct the whole village or settlement on araised platform higher than the high flood level.v) To construct the building with a plinth level higherthan the known high flood level
