The document provides an overview of architectural styles and periods from Early Medieval to Renaissance. It summarizes key features of each style through examples and images, including Carolingian and Ottonian architecture marked by simple plans inspired by Byzantine architecture. Romanesque architecture featured barrel and groin vaults as well as monumental sculpture. Gothic architecture is known for pointed arches, rib vaults, flying buttresses, and stained glass which transformed interiors. The Renaissance saw a revival of classical forms and rationality through architects like Brunelleschi, Alberti, Bramante and designs like Santo Spirito and St. Peter's.
This document discusses architecture and place through three sections. The Phenomenon of Place defines place as a qualitative total phenomenon comprising concrete things that determine environmental character. The Structure of Place examines how settlement, urban spaces, visualization and symbolization give places their structure. The Spirit of Place explores how places foster identification through their essence. The document was prepared by Dr. Nermina Mujezinović using Christian Norberg-Schulz's work on the phenomenology of architecture and place as source material.
Introduction to Arch List of potential questionsHamdija Velagic
These wall construction techniques are typical of ancient architecture from Mesopotamia, Egypt, Greece, and Rome. Masonry techniques like cyclopean walls and stone masonry were commonly used. Orders and architectural elements were adopted by later cultures.
Vertical openings in spaces can articulate edges and separate planes. Openings located at corners help define space boundaries while allowing light to enter and wash adjacent surfaces. Larger openings weaken edges and can blur the definition of corners if they turn them. Corner openings provide orientation cues and can accentuate or illuminate darker areas through incoming light.
This document summarizes key concepts related to building construction formwork, scaffolding, and shoring. It defines formwork as artificial supports provided below and around concrete work, noting that formwork can be made of steel or wood. Factors that affect the cost of formwork include material, erection, removal, and labor costs. Formwork is needed for foundations, walls, columns, slabs, beams, and stairs. Scaffolding provides a temporary work platform at different building levels, and can be single, double, ladder, cantilever, suspended, or steel/tubular. Shoring provides temporary support to unsafe structures and can be horizontal, vertical, or inclined. Sketches of column formwork, double
This document provides information about formwork, scaffolding, shoring, and underpinning. It defines each construction technique and describes the typical components and uses. Formwork supports wet concrete until it cures and is used for foundations, walls, columns, slabs, beams, and stairs.

L'indice de performance des ports à conteneurs de l'année 2023SPATPortToamasina
Une évaluation comparable de la performance basée sur le temps d'escale des navires
L'objectif de l'ICPP est d'identifier les domaines d'amélioration qui peuvent en fin de compte bénéficier à toutes les parties concernées, des compagnies maritimes aux gouvernements nationaux en passant par les consommateurs. Il est conçu pour servir de point de référence aux principaux acteurs de l'économie mondiale, notamment les autorités et les opérateurs portuaires, les gouvernements nationaux, les organisations supranationales, les agences de développement, les divers intérêts maritimes et d'autres acteurs publics et privés du commerce, de la logistique et des services de la chaîne d'approvisionnement.
Le développement de l'ICPP repose sur le temps total passé par les porte-conteneurs dans les ports, de la manière expliquée dans les sections suivantes du rapport, et comme dans les itérations précédentes de l'ICPP. Cette quatrième itération utilise des données pour l'année civile complète 2023. Elle poursuit le changement introduit l'année dernière en n'incluant que les ports qui ont eu un minimum de 24 escales valides au cours de la période de 12 mois de l'étude. Le nombre de ports inclus dans l'ICPP 2023 est de 405.
Comme dans les éditions précédentes de l'ICPP, la production du classement fait appel à deux approches méthodologiques différentes : une approche administrative, ou technique, une méthodologie pragmatique reflétant les connaissances et le jugement des experts ; et une approche statistique, utilisant l'analyse factorielle (AF), ou plus précisément la factorisation matricielle. L'utilisation de ces deux approches vise à garantir que le classement des performances des ports à conteneurs reflète le plus fidèlement possible les performances réelles des ports, tout en étant statistiquement robuste.

Architecture department Date : xx / xx / xxxx
Sarajevo
LECTURE NO.5
CONSTRUCTION EQUIPMENT
Building Construction Technology I
Professor : Prof.dr.Nerman Rustempasic
Assistant : M.Sc. Ahmed El Sayed
2. INTRODUCTION
It is a common fact that we find a wide variety of
construction machines on every construction sites, which
make the construction jobs easy, safe and quicker.
Depending on the application, construction machines are
classified into various categories which we are discussing
here.
A. Earthmoving equipments
B. Construction vehicles
C. Material handling equipments
D. Construction equipments
3.
4. GROUP A : EARTHMOVING EQUIPMENTS
*Earthmoving equipment is used in the construction industry to :
- shift large amounts of earth,
- dig foundations and landscape areas.
*Types of earthmoving equipment include hydraulic excavators,
bulldozers, compressors and loaders.
5. A1 : EXCAVATORS
Excavators are heavy construction equipment consisting of a boom,
stick, bucket and cab on a rotating platform (known as the "house").
The house sits atop an undercarriage with tracks or wheels.
Excavators are also called diggers
Excavators are used in many ways:
Digging of trenches, holes, foundations
Material handling
Brush cutting with hydraulic attachments
Forestry work
Demolition
General grading/landscaping
Heavy lift, e.g. lifting and placing of pipes
Mining, especially, but not only open-pit mining
River dredging
Driving piles, in conjunction with a pile driver
7. A2 : LOADERS
A loader is a heavy
equipment machine often
used in construction,
primarily used to Load
material (such as asphalt,
demolition debris, dirt,
snow, feed, gravel, logs,
raw minerals, recycled
material, rock, sand, and
woodchips) into or onto
another type of machinery
(such as a dump truck,
conveyor belt, feed-
hopper, or railcar).
8. A3 : SKID STEER LOADERS
A skid loader or skid-steer
loader is a small rigid frame,
engine-powered machine
with lift arms used to attach a
wide variety of labor-saving
tools or attachments.
Though sometimes they are
equipped with tracks, skid-
steer loaders are typically
four-wheel vehicles with the
wheels mechanically locked
in synchronization on each
side, and the left-side drive
wheels can be driven
independently of the right-
side drive wheels.
9. A4 : GRADERS
A grader, also commonly
referred to as a road
grader, a blade, a
maintainer, or a motor
grader, is a construction
machine with a long blade
used to create a flat
surface.
Typical models have three
axles, with the engine and
cab situated above the
rear axles at one end of
the vehicle and a third axle
at the front end of the
vehicle, with the blade in
10. A4 : GRADERS
In civil engineering, the grader's
purpose is to "finish grade"
(refine, set precisely) the "rough
grading" performed by heavy
equipment or engineering
vehicles such as scrapers and
bulldozers.
Graders are commonly used in
the construction and maintenance
of dirt roads and gravel roads.
In the construction of paved roads
they are used to prepare the base
course to create a wide flat
surface for the asphalt to be
placed on. Graders are also used
to set native soil foundation pads
to finish grade prior to the
construction of large buildings.
11. A5 : CRAWLER LOADERS
The crawler loader
combines the stability of
the crawler tractor with the
abilities of a wheel loader.
However, to construct a
reliable crawler loader it
requires more than simply
attaching a loader bucket
onto a crawler tractor. It
must be designed with its
specific purpose in mind to
ensure it has the strength
to withstand heavy
excavating.
12. A5 : CRAWLER LOADERS
The introduction of hydraulic
excavators diminished the
market for the crawler loader
because it was unable to match
the excavator's lifting power and
flexibility.
However, crawler loaders are
capable of maneuvering across
the entire construction site
under its own power, whereas
most hydraulic excavators
require towing or transport.
While crawler tractors are still
being manufactured today for
niche markets, they reached
their peak of popularity in the
1960s.
13. A6 : BACKHOE
A backhoe, also called a
rear actor or back actor, is
a piece of excavating
equipment or digger
consisting of a digging
bucket on the end of a two-
part articulated arm. They
are typically mounted on the
back of a tractor or front
loader.
14. A6 : BACKHOE
The section of the arm closest to
the vehicle is known as the
boom, and the section which
carries the bucket is known as
the dipper or dipper stick (the
terms "boom" and "dipper"
having been used previously on
steam shovels). The boom is
attached to the vehicle through
a pivot known as the kingpost,
which allows the arm to slew left
and right, usually through a total
of around 200 degrees. Modern
backhoes are powered by
hydraulics.
15. A7 : BULLDOZERS
A bulldozer is a crawler
(continuous tracked
tractor) equipped with a
substantial metal plate
(known as a blade) used to
push large quantities of
soil, sand, rubble, or other
such material during
construction or conversion
work and typically
equipped at the rear with a
claw-like device (known as
a ripper) to loosen
densely-compacted
materials.
16. A8 : TRENCHERS
Trenchers, or ditchers as
they are sometimes called,
are similar to excavators in
the sense that they
penetrate the earth,
breaking soil and rock, and
remove it from the ground.
They differ from
excavators in that the soil
is removed in one
continuous movement.
Trenchers are specifically
used for digging trenches
for pipes, but other
machines have been
improvised in the past to
17. A8 : TRENCHERS
Trenchers can come in two
types: ladder trenchers
and wheel trenchers, and
can dig trenches at speeds
that other machines
cannot compare to.
18. A9 : SCRAPERS
In civil engineering, a
wheel tractor-scraper is a
piece of heavy equipment
used for earthmoving.
The rear part has a
vertically moveable hopper
(also known as the bowl)
with a sharp horizontal
front edge. The hopper
can be hydraulically
lowered and raised. When
the hopper is lowered, the
front edge cuts into the soil
or clay like a plane and fills
the hopper.
19. A9 : SCRAPERS
When the hopper is full it
is raised, and closed with a
vertical blade (known as
the apron). The scraper
can transport its load to
the fill area where the
blade is raised, the back
panel of the hopper, or the
ejector, is hydraulically
pushed forward and the
load tumbles out. Then the
empty scraper returns to
the cut site and repeats
the cycle.
20. A10 : WHEELED LOADING SHOVELS
A power shovel (also stripping
shovel or front shovel or
electric mining shovel) is a
bucket-equipped machine,
usually electrically powered,
used for digging and loading
earth or fragmented rock and for
mineral extraction.
Power shovels are used
principally for excavation and
removal of overburden in open-
cut mining operations, though it
may include loading of minerals,
such as coal. They are the
modern equivalent of steam
shovels, and operate in a similar
fashion.
21. A10 : WHEELED LOADING SHOVELS
A shovel's work cycle, or
digging cycle, consists of
four phases:
digging
swinging
dumping
returning
22. GROUP B : CONSTRUCTION VEHICLES
* Engineering or Construction vehicles are heavy-duty vehicles,
specially designed for executing construction (Civil engineering) tasks,
most frequently, ones involving earth moving.
23. B1 : DUMPERS
A dumper is a vehicle
designed for carrying bulk
material, often on building
sites. Dumpers are
distinguished from dump
trucks by configuration: a
dumper is usually an open
4-wheeled vehicle with the
load skip in front of the
driver, while a dump truck
has its cab in front of the
load.
24. B1 : DUMPERS
The skip can tip to dump
the load; this is where the
name "dumper" comes
from. They are normally
diesel powered. A towing
eye is fitted for secondary
use as a site tractor.
Modern dumpers have
payloads of up to 10 tones
and usually steer by
articulating at the middle of
the chassis.
25. B2 : TIPPERS
A truck or lorry the rear
platform of which can be
raised at the front end to
enable the load to be
discharged by gravity also
called tip truck.
26. B2 : TIPPERS
Tippers are suited for the
rough and tumble of
mining & quarrying
operations, as well as for
carrying bulk loads in
construction and
infrastructure industries.
Complete maneuverability,
high performance and
long-term endurance are
common to all trucks,
resulting in lower operating
costs.
27. B3 : TRAILERS
A trailer is generally an
unpowered vehicle pulled
by a powered vehicle.
Commonly, the term trailer
refers to such vehicles
used for transport of goods
and materials.
30. C1 : CRANES
A crane is a type of
machine, generally
equipped with a hoist, wire
ropes or chains, and
sheaves, that can be used
both to lift and lower
materials and to move
them horizontally. It is
mainly used for lifting
heavy things and
transporting them to other
places.
31. C1 : CRANES
It uses one or more simple
machines to create
mechanical advantage and
thus move loads beyond
the normal capability of a
man. Cranes are
commonly employed in the
transport industry for the
loading and unloading of
freight, in the construction
industry for the movement
of materials and in the
manufacturing industry for
the assembling of heavy
equipment.
32. C2 : CONVEYORS
A conveyor system is a
common piece of mechanical
handling equipment that
moves materials from one
location to another.
Conveyors are especially
useful in applications
involving the transportation of
heavy or bulky materials.
Conveyor systems allow
quick and efficient
transportation for a wide
variety of materials, which
make them very popular in
the material handling and
packaging industries
34. C3 : FORKLIFTS
A forklift truck (also called a
lift truck, a fork truck, a
forklift, or a tow-motor) is a
powered industrial truck used
to lift and transport materials.
Forklift trucks are available in
many variations and load
capacities. In a typical
warehouse setting most
forklifts used have load
capacities between one to
five tons. Larger machines,
up to 50 tons lift capacity are
used for lifting heavier loads,
36. C4 : HOISTS
A hoist is a device used
for lifting or lowering a load
by means of a drum or lift-
wheel around which rope
or chain wraps. It may be
manually operated,
electrically or
pneumatically driven and
may use chain, fiber or
wire rope as its lifting
medium. The load is
attached to the hoist by
means of a lifting hook
37. C4 : HOISTS
Also known as a Man-Lift,
Buckhoist, temporary elevator,
builder hoist, passenger hoist or
construction elevator, this type
of hoist is commonly used on
large scale construction
projects, such as high-rise
buildings or major hospitals.
There are many other uses for
the construction elevator.
Many other industries use the
buckhoist for full time
operations. The purpose is
being to carry personnel,
materials, and equipment
quickly between the ground and
higher floors, or between floors
in the middle of a structure.
39. D1 : TUNNELING AND HANDLING EQUIPMENTS
A tunnel boring machine
(TBM) also known as a "mole",
is a machine used to excavate
tunnels with a circular cross
section through a variety of soil
and rock strata. They can bore
through anything from hard rock
to sand. Tunnel diameters can
range from a meter (done with
micro-TBMs) to 19.25 m to date.
Tunnels of less than a meter or
so in diameter are typically done
using trenchless construction
methods or horizontal
directional drilling rather than
TBMs.
40. D2 : CONCRETE MIXERS
A concrete mixer (also
commonly called a cement
mixer) is a device that
homogeneously combines
cement, aggregate such as
sand or gravel, and water to
form concrete. A typical
concrete mixer uses a revolving
drum to mix the components.
For smaller volume works
portable concrete mixers are
often used so that the concrete
can be made at the construction
site, giving the workers ample
time to use the concrete before
it hardens.
41. D2 : CONCRETE MIXERS
Special concrete transport
trucks (in–transit mixers) are
made to transport and mix
concrete up to the construction
site. They can be charged with
dry materials and water, with the
mixing occurring during
transport. With this process, the
material has already been
mixing. The concrete mixing
transport truck maintains the
material's liquid state through
agitation, or turning of the drum,
until delivery.
42. D3 : COMPACTORS
A compactor is a machine or
mechanism used to reduce the
size of waste material or soil
through compaction.
In construction, there are three
main types of compactor: the
plate compactor, the "Jumping
Jack" and the road roller. The
roller type compactors are used
for compacting crushed rock as
the base layer underneath
concrete or stone foundations or
slabs.
43. D3 : COMPACTORS
The plate compactor has a large
vibrating base plate and is
suited for creating a level grade,
while the jumping jack
compactor has a smaller foot.
The jumping jack type is mainly
used to compact the backfill in
narrow trenches for water or gas
supply pipes etc. Road rollers
may also have vibrating rollers.
44. D4 : PAVERS
A paver (paver finisher,
asphalt finisher, paving
machine) is an engineering
vehicle used to lay asphalt
on roadways. It is normally
fed by a dump truck. A
separate machine, a roller, is
then used to press the hot
asphalt mix, resulting a
smooth, even surface. The
sub-base being prepared by
use of a grader to trim
crushed stone to profile after
rolling.
46. D5 : SPRAYING AND PLASTERING MACHINES
Plaster spraying allows a
plasterer to skim a drywall more
than five times faster than using
a hand float to apply it. Although
classic gypsum-based plaster
can be sprayed if it is "spray
grade," most plaster sprayers
prefer the organic-based pre-
mixed plaster packaged in a
plastic bag because the plaster
spraying machine does not
need to be cleaned out after the
job is finished, providing that
plaster is kept moist.
47. D5 : SPRAYING AND PLASTERING MACHINES
Worm-drive pump
Most commonly, sprayers have
a worm-drive pump that pumps
the plaster up to a spray gun
that has a large nozzle, usually
4 to 8 mm, that extrudes the
plaster into a chamber on the
end of the gun
Piston pump
Newer types of plaster sprayer
have a piston pump, which has
sufficient pressure to spray
smooth (untextured) plaster
without compressed air.
48. D6 : ROAD ROLLER
A road roller (sometimes
called a roller-compactor,
or just roller) is a
compactor type
engineering vehicle used
to compact soil, gravel,
concrete, or asphalt in the
construction of roads and
foundations, similar rollers
are used also at landfills or
in agriculture.
49. D7 : STONE CRUSHERS
A crusher is a machine
designed to reduce large
rocks into smaller rocks,
gravel, or rock dust.
Crushers may be used to
reduce the size, or change
the form, of waste materials
so they can be more easily
disposed of or recycled, or to
reduce the size of a solid mix
of raw materials (as in rock
ore), so that pieces of
different composition can be
differentiated.
51. D8 : SLURRY&HEAVY DUTY PUMPS
A Slurry pump is a type of
centrifugal pump in physics
principle that increases the
pressure of liquid and solid
particle mixture (aka slurry),
through centrifugal force (a
rotating impeller) and
converts electrical energy
into slurry potential and
kinetic energy.
A pump is a device used to
move fluids, such as liquids,
gases or slurries. A pump
displaces a volume by
physical or mechanical
