Transcript of CONSTRUCTION SITE

Stages

of
construction

How to do the site preparation
what is the site preparation in construction?
Site preparation
is one of the preliminary works to be done for starting construction works
The selected construction site preparation need to be completed properly before the start of construction process.
MAIN TOPIC
Superstructure
COLUMN
In structural engineering

is avertical structural element that transmits,through compressio
n
Columns
are frequently used to support beams

Columns

are frequently used to support beams or arches on which the upper parts of walls or ceilings rest.
FLOOR
In architecture, floors
generally the lower horizontal surface of a room, and/or the supporting structure underneath it
A floor
typically consists of a support structure called a sub-floor on top of which is laid a floor covering to provide a walking surface.
ROOF
Roof
:
the entire covering
assembly.
Roofing
:
that part of the roof which is exposed to the elements
Pitch: rise over run.



SLAB
Concrete slab floors
come in many forms and can be used to provide great thermal comfort and lifestyle advantages. Slabs can be on-ground, suspended, or a mix of both.
They can be insulated, both underneath and on the edges.
Conventional concrete

has high embodied

energy.
BEAM
Beam

are rigid structural members designed to carry and transfer transverse loads across space to supporting elements.
A beam is a structural element that is capable of with standing load primarily by resisting bending.

Non-structures, otherwise known as External Work. External works are minor construction work necessary for and
related to the completion of a site but excluded from and not associated with a particular Structure.
DEFINITION:-

COMPONENTS:
ACCESS ROADS
DRAINAGE SYSTEM
FENCING-SECURITY

A fence is a freestanding structure designed to restrict or prevent movement across a boundary.
Fences are generally distinguished from walls by the lightness of their construction and their purpose.

Proper planning of access roads to the site and with in the site is essential to the efficiency of the projector.
Goals to be achieved:
-
The roads must provide direct access to all points needing access.
The access roads must be built solidly to withstand the loads, traffic and weather conditions
The access roads must be built to accommodate the type of vehicle and load that will use it, which relates to the width of the roadway.

ACCESS TO THE SITE
The construction site is not always accessible by public roads street ,roads need to be constructed from nearest public road to the facility.
Temporary access roads are often needed to until permeant access roads are available.
The access road to the site should be as direct as possible.

ACCESS WITHIN THE SITE
The access roads within the site are rarely designed or defined by the constructor.
Some occasions allow permeant internal roadways to be used during the construction phase.
The contractor should determine the location of these roads, how they will be used and the type of roadway necessary.

The function of the field drainage system is to control the water table, whereas the function of the main drainage system is to collect, transport, and dispose of the water through an outfall or outlet.

CLASSIFICATION OF DRAINAGE

SURFACE DRAINAGE SYSTEM

Surface drainage is the removal of water that collects on the land surface.

A surface drainage system consists of shallow ditches and should include land smoothing or land grading. This type of system is suitable for all slowly permeable soils and or clay subsoil's.


Subsurface drainage system
The process of subsurface drainage systems focus on the removal of water from pavement structure.

Outlet tunnel

lateral ditches
field ditches
Base drainage layer
Filter layer

Collector Pipe.

Outlet Pipe
Characteristics of the fence
Suitable height to deter entry, for example 1.8m.
Constructed from dedicated materials.
Difficult to jump.
Difficult to gain access from underneath.
Stable and able to withstand
anticipated loads.
gates and joints in the fence should be secure and not present a weak point for entry.

Note
: Sheets of reinforcing mesh should not be used for site fencing as it allows adequate hand and foot hold for children to climb over and the protruding ends of sheets could result in penetrating injuries.

foundation
The lowest artificially built part of a structure which transmits the load of the structure to the soil lying underneath is called foundation
The supporting part of a structure; the foundation. (i.e.: footing / piling, pile cap, column stump)
Sub-structure will include ground beams, ground floor column and ground floor slab.

1.
To distribute loads of the structure over a large bearing area so as to bring intensity of loading within bearing area so as to bring intensity of loading within the safe bearing capacity of the soil lying underneath.

2.
To load the bearing surface at a uniform rate so as to prevent unequal settlement. 3. To prevent the lateral movement of the supporting material.

4.
To secure the level and firm bed for building operations.


5.
To increase the stability of the structure as a whole.

Purposes of foundation
Factors affecting selection of foundations.
1. Types and intensity of loads acting on various parts of the structure which may be dead load, live load, wind load, snow load, etc.
2. Nature and bearing capacity of the soil on which the structure directly rests.
TYPES
OF FOUNDATION
Shallow Foundation
Deep Foundation
Pile foundation
• Structures place on top of the piles.
• Piles + Pile Cap = Pile foundation
• Function: Distributes load to the individual piles.
• Pile Cap will connect the Pile Cap will connect the pile together and distributes the superstructure loads to the layer beneath.

Strip Foundation
Pad ( Isolated Foundation )
Raft Foundation
Construction above the basement or foundation, supported by an infrastructure which in turn is supported by the substructure.


Define
Equipment of site preparation construction
Bulldozer
A piece of heavy equipment
used for clearing lots and property. It is used to push over
trees and grade construction sites.

Back Hoe
A piece of heavy equipment
used to excavate and clear land.

A back hoe
is used to
trench and can also be used as a front end loader

Box Blade
Box Blade
is a piece of equipment that is pulled behind a tractor to pull and level dirt.
The blade
or box can be tilted so the blade will either dig deeper to collect dirt or skim
across the top to level the dirt.

Site layout plan
site clearing
A site layout plan

is a construction plan prepared by the contractor as part of their mobilisation activities before work on site commences.

Locations of cranes
Site offices
Welfare facilities
Off-loading and storage areas.
Hoarding and temporary services
Entrances, temporary roads
Car parking
Sub-contractor facilities

A door is a movable barner provided in the opening of a wall, to provide access to various spaces of a building. A door is a frame work of wood, steel etc. secured in the wall opening for the purpose of providing access to the users of the building. Similarly, a window may be defined as an opening made in (the wall be the purpose of providing day light, vision and ventilation. Windows are also made of frame work of wood, steel, aluminum etc., provided with shutters.
