The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.
This is a presentation by Dada Robert in a Your Skill Boost masterclass organised by the Excellence Foundation for South Sudan (EFSS) on Saturday, the 25th and Sunday, the 26th of May 2024.
He discussed the concept of quality improvement, emphasizing its applicability to various aspects of life, including personal, project, and program improvements. He defined quality as doing the right thing at the right time in the right way to achieve the best possible results and discussed the concept of the "gap" between what we know and what we do, and how this gap represents the areas we need to improve. He explained the scientific approach to quality improvement, which involves systematic performance analysis, testing and learning, and implementing change ideas. He also highlighted the importance of client focus and a team approach to quality improvement.

We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.

steel, bricks, concrete and metal plates to form the
framework of traditional architecture and spatial order
to reinterpret modern residential construction. This
residential building uses both steel frame structures and
composite metal decking for its floors.
Building Technology 1: Construction Solutions |
6. 6
Advantages
1. Fast to build at site, as the majority of work can be
pre-fabricated at the factory.
2. Steel structures are flexible and good at resisting
wind and earthquake forces.
3. Strong and durable, and does not warp or expand
unlike traditional wood framing.
4. A wide range of pre-made structural sections are
available and they are suitable to clad with any
material.
5. Able to span long distances.
6. Has a variety of joining methods including bolting,
welding and riveting.
Disadvantages
1. Lose strength at high temperatures and susceptible
to fire so coatings are required.
2. Prone to corrosion in tropical and humid
environments.
Integration to Community Library
Steel frame constructions allow a larger structural spans
and efficient when laid out along a regular grid,
especially when the site has a long distance from front
to rear.
The brick structure combined with the modern steel
structure to produce a unique local architectural type.
This brings a sense of locality with the neighbouring
shoplots which are of solid masses as well. Masonry also
possess good insulation properties for acoustics needed
in the community library. Salvaged bricks from the
existing building can be reused for the new library.

2.0 Precedent Studies | 2.1 Structural Steel Frame
Steel Frame Structures
Steel construction has an immense strength which
is an advantage to buildings. It can bend with
cracking and can flex when wind or earthquake
forces acting on it. Various connection joints are
concurrently used throughout the steel system to
further strengthen the connections between
structural members and the masonry walls.
7. 7
Construction Process
1. After the concrete foundation has set up, steel base plates are anchored and attached to
the foundation with four anchoring bolts. The plates are levelled on a bed of non-shrinking
grout.
2. The steel columns are lowered and welded to these base plates. The plates are used to
transfer concentrated load from the columns to the ground.
3. Primary ground floor beams are connected to the columns via fin plates. The plates are
welded with the column and bolted to the web of the beams.
4. Secondary floor beams are connected to the primary beams through a similar method.
5. The ground flooring is prepared through composite decking. The composite process is
done by welding sheer studs through the steel decking to the supporting steel beam
below. [See Composite Floor System] Infill brick walls are then placed.
6. For the upper floors, more columns are erected and connected through splices. The splices
provide strength and stiffness to both the columns. The splices are bolted to both the
columns.
7. The process is repeated for the flooring system.

2.0 Precedent Studies | 2.2 Composite Floor System
Advantages
1. No evidence of nails and has a nice flat finish.
2. Steel and concrete may be arranged to produce
ideal combination of strength, with concrete
efficient in compression and steel in tension.
3. The construction time is reduced since casting of
additional floors may proceed without having to
wait for the previously cast floors to gain strength.
4. The construction of composite floor does not
require highly skilled labour. The steel decking acts
as a permanent form work.
5. Composite decking offers excellent resistance to
corrosion, chemical attack and outdoor weathering.
Disadvantages
1. Temperature sensitive and expands and contracts
with temperature change.
2. If damaged or faded, the material must be
replaced.
3. A soft material and wears easily.
Integration to Community Library
The lightweight properties of composite decking allows
the sizes of other structural components to be greatly
reduced, permitting smaller interiors and the possibility
for open floor plans.
Composite flooring has a much smaller depth compared
to reinforced concrete floor slabs. This allows flexibility
in design and at the same to withstand greater loads.
Ceiling heights can be significantly increased.
Composite Flooring
Composite decking serves as a tensile
reinforcement for the concrete slab to
which it is bonded with embossed rib
patterns.
9. 9
Construction Process
1. Trapezoidal steel decking is placed and spanned in a direction transverse to the secondary
floor beams.
2. The decking is rigidly connected to the primary and secondary beams by shear studs,
which are connected through deck-welding techniques.
3. Steel mesh reinforcement, i.e. rebars, is placed above the steel decking to provide
bending resistance and reduce cracking at the supports. The mesh also aids the
distribution of the effects of localised point and line loads.
4. The profiled steel decking acts as a formwork during construction and additional external
reinforcement at the final stage of construction when reinforced concrete is cast on top of
it.

Discovery Centre | Architecture Discipline
This city town hall located in Karnataka, India serves as a
office/sales office and the design brief demanded the
exploration of sustainable design and development.
The exposed roof structure utilizes longitudinal steel
trusses for the long building span and topped with
polycarbonate sheeting to allow diffused lighting into
the interior.
11. 11
Advantages
1. The simple mechanism of longitudinal steel trusses
of the roof allows simple and fast construction.
2. The lightweight of the roof truss members reduces
the typical bulkiness of structural members.
3. Steel roof trusses allow larger spans, which
contributes to the need of lesser columns. An open
floor plan can be achieved and it is economical.
4. Lightweight polycarbonate sheet is lightweight and
reduces the sizes of columns supporting the roof.
5. Using a truss system aids in keeping the roof light,
brings light inside and enables controlled
surrounding views of the site.
6. The fabric louvers arranged in angular between the
trusses allows soft and diffused light to penetrate
into the interior spaces. Thus, exposed ceiling can
be achieved.
Disadvantages
1. Skilled labour is required to install these steel roof
trusses.
2. Rust can be a problem when the metal is cut, drilled
and welded if no proper coating is done on the
structural members.
Integration to Community Library
Longitudinal steel roof trusses are encouraged to be
used as the roof system in the community library as it
can span long distances especially when our site is long
in length. The installation of steel trusses also means
that lesser and smaller sized columns can be used to
support the roof structure. This allows an open floor
plan of the community library which contributes to more
interior spaces.
The ceiling can be left exposed as it is as steel trusses
can be aesthetically pleasing when viewed. The
lightweight fabric louvers installed on the structural
members bring in soft and diffused light into the interior
spaces.

Construction Process
1. The steel trusses are pre-fabricated in the factory. The diagonal web
members are welded and bolted to both top and bottom chords of the steel
trusses.
2. The primary steel trusses are brought to site and assembled to the structural
steel beams through welding. Both beams and trusses sit on the round
columns of the building.
3. Roof purlins are laid on the trusses of varying heights to allow a small
degree of roof pitch. The purlins are then fasten through bolting and
welding to the top chord of the steel trusses.
4. Polycarbonate sheeting is laid and nailed with fastening plates on the
purlins.
5. The translucent fabric layer is installed right below the top chord of the truss
and secured onto the structural steel beams.
6. Perforated fabric louvers are aligned and angled between the trusses. Some
layers are overlapped with one another to allow natural light to diffuse into
the interior spaces below.

CASP 74 | Bach Arquitectes
The CASP 74 apartment is located in Barcelona, Spain.
The design of the building responds to the necessity of
the modern era and the facade is composed as a
dialogue between fixed panels formed by steel framed
vertical ceramic planks, and sliding aluminium blinds
providing the necessary privacy and lighting control.
15. 15Building Technology 1: Construction Solutions |
2.0 Precedent Studies | 2.4 Operable Blinds Facade System
Advantages
1. The changing façade provides solar protection and
privacy.
2. Folding aluminium blinds creates dynamics when is
viewed from the street and allows lighting control.
3. The façade prevents heat from getting into the
interior spaces during summer due to the ceramic
planks, so it seals to keep warmth.
4. Aluminium is a lightweight material which makes
the blinds easy to handle and less expensive to
transport.
5. The blinds are durable and less susceptible to
corrosion as aluminium has its own naturally
occurring oxide film.
Disadvantages
1. The blinds can be noisy at the window when it is
operated because they are metal.
2. Tendency to accumulate dust over time, which is
most noticeable on darker coloured vanes.
Integration to Community Library
The implementation of vertical blinds especially with
aluminium as the material is perfect for controlling light
in accordance to the time of the day. It is modern
looking yet classic which fits the ambience of the site of
Jalan Tuanku Abdul Rahman – the mix of classic and
contemporary.
The blinds can be obtained in a wide range of colours
to complement with the surrounding building facade
and interior spaces perfectly. While the vertical blinds
offer different levels of privacy which is needed for the
library spaces, it can be remote control operated by the
librarians.

Weill Cornell Medical College
Belfer Research Building | Todd Schliemann & Ennead Architects
The Belfer Research Building of Weill Cornell Medical College is a medical research
facility in New York, United States. The building envelope features a high-
performance double-skinned, fritted-glass curtain wall that maximizes energy
efficiency. The passively vented system is designed to promote controlled convection
within the wall cavity to mitigate extreme temperatures and enhance thermal comfort
within the building.
18. 18
Advantages
1. The double-skinned facade helps to promote
energy efficiency.
2. Passive vented system promotes controlled
convection within the wall cavity, mitigating
extreme temperatures on the exterior of the
building, and significantly reduces temperatures on
the interior glass.
3. Openings and sun-shading devices enhance visual
and thermal comfort within the interior spaces,
reducing the carbon footprint of the building.
4. Curtain wall design provides an economically
sensitive sustainable solution.
Disadvantages
1. The view to the exterior from the building may be
obstructed.
2. The wall cavity results in a decrease in usable floor
space.
3. The construction of a second skin presents a
significant increase in materials and design costs.
Integration to Community Library
Introducing the double-skinned facade in a community
library is feasible as the wall cavity acts as a buffer zone
to tackle noise coming from the street to allow quiet
interior spaces. For a tropical country, the facade
reduces solar heat gain in the interior spaces and
promotes thermal comfort for the users.
This double building envelope approach offers glare
protection which is helpful for reading activities and
promotes good daylighting method which subsequently
minimizes the need of artificial lighting.
