QUALITY

• Quality is consistent conformance to customers’ expectations.
• In construction, a measure of excellence or a state of being free from

defects, deficiencies and significant variations.

• Quality is directly linked to the formal contract requirements,

specifications, agreements, client preferences and instruction that
undoubtedly influence every technical and commercial decision made from
the boardroom to the project site.

QUALITY ASSURANCE

Refers to the engineering activities implemented in a quality system so that requirement for

a product / service will be fulfilled.

It is the systematic measurement, comparison with a standard, monitoring of processes

and an associated feedback loop that confers error prevention.

This can be contrasted with quality control, which is focused on process outputs.
Two principles included in QA are:

a)Fit for purpose – the product should be suitable for the intended purpose
b)Right first time – mistakes should be eliminated
 QA includes management of the quality of raw materials, assemblies, products and

components, services related to production, and management, production and inspection
processes.

Quality Management System (QMS)

• A system by which an organizations to reduce and eventually eliminate non-conformance to specifications, standards and

customer expectations in the most cost effective and efficient manner

• Elements of QMS:

1) Organizational structure
2) Responsibilities
3) Data management
4) Process – including purchasing
5) Resources – including natural resources and human capital
6) Customer satisfaction
7) Continuous improvement
8) Product quality
9) Maintenance
10) Sustainability – including efficient resource use and responsible environmental operations.
11) Transparency and independent audit
12) Corrective and preventive action
13) Preparation of quality alert chart
14) Engineering change control

GREEN TECHNOLOGY

[email protected]

Definition of Green Technology

• Green Technology is the development and application of
products, equipment and systems used to conserve the natural
environment and resources, which minimize and reduces the
negative impact of human activities.

Definition of Green Building

• Green building, or sustainable design, is
the practice of increasing the efficiency
with which buildings and their sites use
energy, water, and materials, and
reducing building impacts on human
health and the environment over the
entire life cycle of the building. Green
building concepts extend beyond the
walls of buildings and can include site
planning, community and land use
planning issues as well.

WHY SO MUCH INTEREST IN GREEN
CONSTRUCTION?

• Sustainable development has become a global issue.
• Global climate change has become an increasingly serious concern

for the future.
• Concern over the impact of built environment on natural

environment, economy, health and productivity.



Element of Green Buildings

• Sustainable site
development

• Water conservation
and savings.

• Energy efficiency
• Resource efficient

materials
• Healthy indoor

environmental
quality



Importance of green building in construction

• The growth and development of our communities has a large impact on
our natural environment. The manufacturing, design, construction, and
operation of the buildings in which we live and work are responsible for
the consumption of many of our natural resources.

• Environmental Benefits
a) Enhance and protect biodiversity and ecosystems
b) Improve air and water quality
c) Reduce waste streams
d) Conserve and restore natural resources

• Economic Benefits
a) Reduce operating costs
b) Improve occupant productivity
c) Enhance asset value and profits
d) Optimize life-cycle economic performance

• Social Benefits
a) Enhance occupant health and comfort
b) Improve indoor air quality
c) Minimize strain on local utility infrastructure
d) Improve overall quality of life



What does the
Recycling
Symbol Mean?

What are the
three R’s of
Recycling?

Reduce

• Reduce means to use less of
something. Some examples are:

1. Use a handkerchief instead of
tissues.

2. Use a cotton rag when cleaning
house instead of paper towels.

3. Use a sports bottle instead of
buying bottled water everyday.

Reuse

• Reuse is to put again into
service without changing.
Examples are:

1. Wrapping paper

2. Floppy disks

3. Plastic grocery bags

Recycle

• Recycle is to put again
into service with changing.
Examples are:

1. Cans

2. Glass

3. Plastics

Things that
can be
recycle.

Items
cannot
recycle

How can Recycling conserve
our natural resources?

• Recycling conserves natural resources
by substituting “secondary resources”
such as glass, metal, and paper for raw
materials extracted.

• By recycling paper the need to cut down
trees reduces.

• By recycling aluminum it minimizes the
need for mining new minerals, thereby
decreasing damage to the wilderness.

How does Recycling save energy?

• The energy required to
manufacture paper,
plastics, glass, and metal
from recycled materials is
usually less than the energy
required to produce them
from new materials.

• The steps such as
collection, processing, and
transportation is also
usually less energy then the
steps in supplying new
materials.
