Abstract
This project is a model sketch of various aspects of project planning and monitoring of a
house to be built under Prime Minister’s Awaas Yojana. PMAY was launched in 2015 with
an aim to provide housing for all by 2022. This scheme provides a house of 30 sqm carpet
area to an economically weaker section (EWS) household. Houses are supported with basic
civil amenities.
This report covers the planning, scheduling, and monitoring of progress in hypothetical cases
of a single EWS house.

Introduction
Project plan:
The project consists of planning all the
stages of construction of 324 sq. ft house
for the families affected by tsunami in
Tamil Nādu. The house is single storey
and has 1 bedroom, 1 hall, 1 kitchen and
open verandah space.
Purpose of the project:
The project is about planning the
different phases of construction of
Residential Home Construction. This
includes preparing of WBS, BOQ, Gantt
chart, Network diagram, Cost analysis,
budgeting, time cost trade off analysis,
resource planning and earned value analysis.
Project planning-scheduling-execution:
The planning includes, listing all the activities and preparing the work breakdown structure
for all the construction activities and non-construction activities and dividing them in several
packages. After that, AON network diagram is prepared and project duration, float and
critical path is calculated using forward and backward pass. A detailed Gantt chart is
prepared to follow for all the phases of construction. After calculating the time required for
the project, a detailed costing and budgeting is done for every work packages. Time-cost
trade off analysis is done to check the effect on budget cost on crashing several activities. To
manage the resources in the site, resource histogram is prepared for all the human resources.
And, finally Earned Value analysis is done to check the schedule performance and cost
performance for 25%, 50% and 75% of project duration.
Stakeholders:
This is the project to give permanent households for people living in tsunami affected areas.
So, the major stakeholders include:
1. SEVAI(Client)
2. Contractor
3. Sub-contractors
4. Planner
5. Architects
6. Engineers
7. Government authorities
8. Workers and Suppliers
9. Local residents
10. End Users (People affected by tsunami)

Risk and contingencies:
Several points are discussed before the project approval for minimizing the risks and timely
completion of the project:
1. The risk of obtaining planning permission or other statutory approvals: This might
be mitigated by early consultation with statutory authorities prior to design, or by
employing ex-statutory authority employees, or consultants familiar with the statutory
authority.
2. Non-delivery of materials: An alternative design might be prepared, or bulk or
specific items could be pre-ordered before contractors are appointed
3. Lack of available work force. This could be tackled by the provision of
a site labor camp or by overseas recruitment.
4. Illness: This could be mitigated by insurance cover for key personnel.
5. Failure of power or water supply: This might be mitigated by the duplication
of supply, uninterrupted power supplies or the provision of standby generators.

Price Escalation: Escalation is the change in cost or price of specific goods or services in a
given economy over a period.
For any project, budget for materials shall be prepared by considering the price during
procurement in future. For estimating escalation, trend in price increase is studied and
extrapolated.

Analysis of project
Work Breakdown System of the project
The project has been divided into two parts i.e., Planning phase and Construction phase.
Planning phase is comprised of Site survey, Field tests, Design and Approvals.
Construction phase is divided in four parts – Structure, Masonry, Electrical and Plumbing,
and Finishing.

Project Scheduling
Project scheduling is done by two methods:
• AON diagram:
▪ AON diagram is prepared for the project considering duration
calculated of each activity and appropriate predecessor and
successor of each activity.
▪ Backward and forward pass method is used to calculate the total
duration for the completion of the project and float available for
each activity.
▪ No of work packages in the pre-construction phase: 1
▪ No of work packages in the construction phase: 4
▪ Total no of work packages: 8
▪ No of activities in the pre-construction phase: 4
▪ No of activities in the construction phase: 40
▪ Total no of activities: 44
▪ Duration of pre-construction phase (days): 33 days
▪ Duration of construction phase (days): 96 days
▪ Total duration (days): 129 days
▪ Number of non-critical activities: 7
▪ No of critical paths: 2
• Gantt Chart:
▪ Gantt chart for the project is prepared to schedule each activity over the calendar
to show the interrelation between the activities and to track the progress of the
construction.
