Sub section 1.2

PROBLEM–CAUSE–EFFECT–SOLUTION

Dissertation Topic

Development of an AI-based Decision Support System for Prediction and Mitigation of Construction Project Delays using Technical, Cost and Human Behavioral Factors

1. INTRODUCTION & BACKGROUND

Construction is one of the most critical sectors for national development because it creates:

roads
bridges
hospitals
schools
housing
public infrastructure

However, across and globally, construction projects frequently suffer from:

schedule delays
cost overruns
poor quality
worker stress
stakeholder conflict
public inconvenience

Example: A bridge planned for 24 months gets completed in 36 months.

Delay = 12 months (50% overrun)

This is a major engineering and societal problem.

2. PROBLEM STATEMENT

Traditional project planning tools such as:

Microsoft Project

Oracle Primavera P6

are excellent for scheduling, but they are largely:

❌ reactive
❌ static
❌ unable to predict dynamic disruptions

They fail to capture:

labor behavior
communication failures
environmental uncertainty
real-time human risk

Therefore: A predictive, intelligent, and human-centered project management system is required.

3. DATA FACTS (Why this problem matters)

Global Evidence

According to :

only ~50–55% of projects finish on time
~45% experience delays
many exceed cost targets

Meaning: 1 out of every 2 projects faces delay risk.

Construction Sector Evidence

Research commonly reports:

60–80% of construction projects experience delays
average schedule overrun = 20–40%

Example: 24 months planned → 30–34 months actual

India Context

In :

infrastructure delays affect highways, housing, railways, and public works.

In / :

monsoon disruption
festival migration
sand/material shortage
contractor payment delays

These make prediction harder.

4. ROOT CAUSES

A. Technical Causes

weak planning
inaccurate scheduling
design changes
poor resource allocation

Research shows:

planning failure contributes ~20–30%
design changes ~10–20%

B. Financial Causes

delayed payments
inflation
under-budgeting
contractor cash-flow issues

Evidence: Payment delays contribute 15–25% schedule slippage.

C. Human Behavioral Causes (Your Novelty)

Most existing models ignore this.

Examples:

labor absenteeism
engineer burnout
communication breakdown
team conflict
leadership failure
low morale

Evidence:

absenteeism reduces productivity 10–25%
communication is among top 5 delay causes

Links to:

D. Environmental / Regional Causes

monsoon
material shortage
policy restrictions
festival migration

Evidence: Monsoon can reduce 20–60 workdays/year in Eastern India.

5. EFFECTS

Economic Effect

Delays cause:

cost escalation
contractor losses
GDP productivity loss

Evidence: Project cost can rise 5–30%.

Example: ₹10 crore project delayed by 1 year → major escalation.

Social Effect

Delayed:

hospitals
schools
roads
water systems

Impact: Thousands to millions affected.

Example: Delayed rural road = villages disconnected.

Human Effect

Long delays increase:

worker stress
accident exposure
burnout
family instability

Important: Project delay is not only technical—it is human.

Environmental Effect

Longer construction causes:

more diesel use
more emissions
more waste

Supports: reduction.

6. PROPOSED SOLUTION

Build an:

AI-based Decision Support System (DSS)

Functions:

predicts risk early
estimates delay duration
identifies root causes
gives alerts
recommends mitigation

Example:

Input:

labor absenteeism = 22%
rain days = high
payment delay = 40 days

Output: 🔴 HIGH DELAY RISK

Recommendation:

deploy reserve labor
revise schedule
increase contingency

This transforms management:

Reactive → Predictive → Preventive

7. YOUR NOVEL ADD-ON (Main Contribution)

Your innovation is not only AI.

It is:

Human-Centered Predictive Project Intelligence

This creates a human-centered, sustainable, and welfare-oriented project management model for future infrastructure systems.”

FINAL THESIS TAGLINE

“From Delay Prediction to Human-Centered Sustainable Project Intelligence.”

This is your unique identity in and makes your dissertation stronger, more original, and more impactful.

If you want a topic that solves a real unsolved problem—something not commonly done yet—then don’t do just “AI for delay prediction.” That is already crowded.

You need a next-generation problem statement.

Use this principle:

Present problem + missing dimension + future need + universal benefit = truly novel dissertation

Below are original topic ideas using that principle.

OPTION 1 (Strongest): Human + AI + Ethics + Sustainability

“Development of a Human-Centered Ethical AI Framework for Predicting and Preventing Construction Project Failure”

What is new?

Most studies ask: “Will project delay happen?”

Your system asks:

Will project fail?
Will workers burn out?
Will team conflict increase?
Is the AI recommendation ethical and fair?

Add:

fairness score
worker well-being score
ethical decision score

New field:

Why unique? Very few construction studies include AI ethics + human welfare.

OPTION 2 (Most futuristic): Emotional Digital Twin ⭐

“Emotional Digital Twin for Construction Project Management using AI and Human Behavioral Signals”

What is a digital twin? A virtual copy of a real project.

Your new add-on: Not only physical twin— also emotional twin.

Tracks:

stress
morale
fatigue
conflict
leadership health

Meaning: A “health monitor” for the project team.

Uses:

wearable data (optional)
surveys
AI

Fields combined: +

This is extremely novel.

OPTION 3: Project Immunity System (my favorite original concept)

“Construction Project Immune System (CPIS): A Self-Healing AI Framework for Autonomous Risk Detection and Recovery”

Inspired by: human immune system.

How it works:

detects threat
diagnoses problem
activates response
learns for future

Like body immunity, but for projects.

Example: labor shortage detected → automatic schedule correction.

Concept: self-healing project management

This is very original.

OPTION 4: Family & Workforce Stability Model (very unique)

“Impact of Worker Family Stability on Construction Project Performance: An AI-based Predictive Framework”

Radical idea: family stress → worker stress → absenteeism → delay

Almost nobody studies this directly.

Variables:

family conflict score
financial stress
sleep quality
attendance

This is bold and socially meaningful.

OPTION 5: Climate-Resilient Project Intelligence

“AI-based Climate Adaptive Construction Scheduling for Monsoon and Extreme Weather Regions”

Problem: Climate change makes schedules unreliable.

System predicts:

rain
flood risk
heat stress
material disruption

Links to:

Great for context.

OPTION 6: Universal Welfare Project Index (very original)

“Universal Welfare Index for Infrastructure Projects: Beyond Cost and Time”

Today success = cost + time.

You redefine success as: Success =

This creates a new metric: Universal Project Welfare Index (UPWI)

Measures:

human happiness
community benefit
carbon impact
time
cost

Very philosophical + publishable.
