The document discusses the building lifecycle and construction process. It describes the typical stages as initiation, planning, execution, performance and monitoring, and closure. Demolition is then discussed as the final stage where hazardous materials are removed, plans are prepared, and safety measures are taken before non-explosive or explosive demolition. Waste treatment involves managing over 450 million tons of annual construction and demolition waste through reducing, reusing, and recycling materials.

2. BUILDING LIFECYCLE
• Building life cycle refers to the view of a
building over the course of its entire life,
viewing it not just as an operational building,
but taking into account the design, construction,
operation, demolition and waste treatment.

4. CONSTRUCTION BUILDING CYCLE
• A construction project entails 5 important stages:
1)Initiation
2)Planning
3)Implementation
4)Performance
5)Monitoring and closing

5. INITIATION
5
• The initiation phase begins with identifying a project objective, and recording the need.
• After determining the project objective, those involved develop a list of proposed solutions and
study the feasibility of each option.
• If stakeholders approve the solution, they appoint a project manager to oversee the process. This
phase also involves building a project team and identifying the deliverables.
• The project manager approves the team and deliverables, and the project may move to the next
phase.

6. PLANNING
The planning phase involves further developing the project to determine how to meet the project's
objective.
• The team identifies the work to be done and the tasks and resources required.
• The final product is a project plan that outlines certain aspects of the project, such as its:
❑ Activities
❑ Dependencies
❑ Tasks
❑ Time frames
6

7. EXECUTION
• The execution phase includes the implementation stages of the project. The team performs most of
the work on the project on-site, and the project manager maintains control and communication
through each implementation stage.
• While teams strive to follow project plans exactly, some variances or adjustments may occur. The
project manager records all adjustments or variances and makes corrective measures as needed
to ensure the project continues as planned.

8. PERFORMANCE AND MONITORING
• The performance and monitoring phase happens concurrently with the execution phase. It includes all
measurements of progress and performance.
• Project managers should provide status reports regularly that follow the previously agreed-upon
format. Here are some elements to include:
❑Cost
❑Quality
❑Schedule
• The project manager reviews each deliverable against the customer acceptance criteria and approves
them. The customer agrees to the final solution, and the project is ready for closure.

9. CLOSURE
• The closure phase involves the project manager providing all the final deliverables to the
customer.
• The project manager and team may evaluate the success of the project. They may identify things
that went well and things that didn't.
• The project manager will use this feedback to improve future team projects.

12. INTRODUCTION
• WE KNOW EVERY STRUCTURE IS DESIGNED FOR A LIFE PERIOD.
• THE EXISTENCE OF THE STRUCTURE AFTER THE SERVICE LIFE PERIOD IS VERY DANGEROUS TO
ITS OCCUPANTS AND SURROUNDING BUILDINGS.
• THE BUILDING ACT USUALLY CONTAINS PROVISIONS THAT ENABLE LOCAL AUTHORITIES TO
CONTROL DEMOLITION WORKS FOR THE PROTECTION OF PUBLIC SAFETY AND
TO ENSURE ADJOINING PREMISES AND THE SITE ARE MADE GOOD ON COMPLETION OF
THE DEMOLITION

13. DEMOLITION
• DEMOLITION IS THE PROCESS OF TEARING DOWN OR FALLING DOWN OF A BUILDING AFTER
ITS LIFE PERIOD WITH THE HELP OF SOME EQUIPMENTS OR ANY OTHER METHOD.
•
• WHEN EXPLOSIVES ARE USED FOR THIS THEN THE DEMOLITION PROCESS ARE CALLED AS AN
IMPLOSION.

14. STEPS BEFORE DEMOLITION
• >THE DIFFERENT STEPS BEFORE THE EXECUTION OF A DEMOLITION PROCESS ARE:
• 1. SURVEYING
• 2. REMOVAL OF HAZARDOUS MATERIALS
• 3. PREPARATION OF PLAN
• 4. STABILITY REPORT
• 5. SAFETY MEASURES

15. SURVEYING
• Surveying means study of different parameters of the structure and its surroundings.
• There are two types of surveying are mainly conducted. They are
• A. Building surveying
• B. Structural surveying

16. WASTE TREATMENT

17. WASTE MANAGEMENT
• Waste management is a mechanism of
origination, storage, assortment, handling,
processing and disposal of generated
waste materials ensuring healthy
environmental conditions.
• More than 450 million tonnes per year
construction and demolition waste is
generated. Though the construction and
demolition waste are having highest
recovery potential to achieve almost 80%
recycling or reuse. However, on ground
reality out of it 80%, a maximum 5% of
waste is actually recovered and balance
75% of waste is being landfilled

18. WASTE MANAGEMENT
Any new building construction generates
40-60 kg of construction and demolition
waste per sqm, India is generating 50
million tons construction and demolition
waste per year for new building
construction programs.
Demolition and modification activities
generate 300-500 kg of waste per sqm
which is 10 times more that any new
construction activity.

If the steel-framed structure is ,volume of
concrete debris waste can be reduced by
50% hence reducing construction and
demolition waste by 33%.

20. WASTE MANAGEMENT
Life cycle assessment must be followed for
all the construction materials to promote the
principle of 3R Reduce, Reuse and Recycle.
In addition that government must introduce
stringent construction code specifically to
emphasize the use of the recycled materials
and alternative building materials
Use of recycled block paver and floor tiles
manufactured using construction and
demolition waste.
Further tax policies must be formatted to
promote the use of recycled waste products
