📌 Project: Construction Project Management Web Application

📅 Date: July 23, 2025

---

1. Overview

A web-based construction project management system designed to manage projects by breaking them down into subprojects, mini-projects, and tasks. The system supports team assignments, role definitions, equipment tracking, time and budget management, and communication.

2. Core Features

Module	Description
Project Hierarchy	Create and manage a hierarchy: Project → Subproject → Mini Project → Task
Team Management	Assign teams per mini-project; define roles and responsibilities
Role & Responsibility Definition	Define duties for Team Lead, Engineers, Operators, Laborers, etc.
Equipment Assignment	Allocate equipment (e.g., excavators, tools, PPE) to team members/tasks
Task Assignment	Assign tasks with due dates, budgeted time, assignees, dependencies
Time Tracking	Log daily time per task; compare with estimated time
Budget Tracking	Track time and cost overruns; visualize budget vs actual
Commenting & Discussion	Task-specific communication threads
Notifications	Alerts for task due, time overrun, unassigned resources
Reports & Dashboards	Summary views per project, user, team, and equipment

4. Data Models (Simplified)

Project Structure

Project
  └── Subproject
        └── MiniProject
              └── Task

Key Entities

• User: id, name, email, role, team_id

• Team: id, name, project_id

• Equipment: id, name, type, status, assigned_to

• Task: id, title, description, mini_project_id, assignee_id, estimated_time, logged_time, due_date, status, priority

• Comment: id, task_id, user_id, message, timestamp

• TimeLog: id, task_id, user_id, hours_logged, date

---

5. User Roles

Role	Access
Admin	Manage all data, assign roles, system config
Project Manager	Create projects, assign teams and tasks
Team Lead	Assign duties within the team, report progress
Engineer/Operator	View and update assigned tasks
Laborer	Log time and mark task status

6. UI Modules (Frontend Pages)

Page	Description
Dashboard	Summary of projects, tasks, alerts
Project Hierarchy	Expandable view of project > subproject > mini-project > tasks
Task Detail Page	Like the image you uploaded — full task breakdown, team info, comments
Team Management	Assign members, define duties
Equipment Tracker	Assign tools and monitor usage
Reports	Time, cost, resource utilization, task delays

7. API Design (Sample Endpoints)

Method	Endpoint	Description
GET	/api/projects/:id	Get project with subprojects
POST	/api/tasks	Create new task
PUT	/api/tasks/:id/assign	Assign task to user
POST	/api/timelog	Log time for task
GET	/api/reports	Get summary reports

8. Security

• Password encryption (BCrypt)

• JWT-based session management

• Role-based access control (RBAC)

• CSRF and CORS protection

---

9. Performance Considerations

• Lazy loading for task trees

• Indexed queries for task and user filters

• API pagination for logs and comments

---

10. Scalability

• Microservice-ready backend (modular design)

• Database sharding (in future)

• CDN usage for static assets

---

11. Integration (Future Phase)

• Email/SMS notifications (e.g., SendGrid, Twilio)

• Calendar sync (Google Calendar, iCal)

• Equipment telemetry (IoT data support)

---

✅ Deliverables

• Web-based project management platform (MVP)

• Admin panel

• User manual and system documentation

• Training for client staff
