SIEC — Intelligent Construction Estimation System

SIEC is a web platform for intelligent construction estimation, 2D/3D spatial planning, material analysis, layout management, and project portfolio analytics.

The platform is designed to help construction, architecture, and engineering teams model spaces, validate available area, visualize projects in real time, and support cost estimation workflows through a modern SaaS-style interface.

Overview

SIEC combines a 2D room editor, a real-time 3D viewer, area validation, material configuration, project dashboards, and SIEC Place into a single construction estimation workflow.

The system focuses on turning early-stage spatial decisions into measurable project data. Users can create rooms, apply base layouts, review available area, visualize the project in 3D, and prepare the foundation for cost estimation and technical reporting.

Core Features

Design and Simulation

• 2D room editor for spatial planning.
• Real-time 3D visualization powered by WebGL.
• Room creation, resizing, positioning, and layout management.
• Base templates and saved layouts.
• Surface usage validation and available area tracking.

Estimation and Analysis

• Material-based project configuration.
• Construction cost estimation workflow.
• Budget-oriented project breakdowns.
• Project dashboard for saved simulations.
• SIEC Place: project marketplace to publish budgets and connect with contractors (Pro+ plan).

Product Experience

• Premium dashboard and workspace interface.
• Product preferences for editor, estimation, and export behavior.
• Dark mode support.
• Authentication and account settings when configured.
• Modular frontend architecture based on views, components, stores, and composables.

Product Modules

Module	Purpose
Workspace	Main 2D/3D construction simulation environment.
Dashboard	Project access, overview, and quick project management.

Settings	Account, security, product preferences, integrations, and plan overview.
Backend API	Business logic, data access, and service integration layer.
Database	Relational persistence for structured project and system data.
Scraper	Price collection and normalization module, when enabled.

Technology Stack

Area	Technology
Frontend	Vue 3, Vite, TailwindCSS
State Management	Pinia
Routing	Vue Router
3D Rendering	Three.js
Backend	FastAPI
Database	PostgreSQL
Authentication	Supabase
Infrastructure	Docker, Vercel, Railway

Architecture

Frontend Vue/Vite
    -> FastAPI Backend
        -> PostgreSQL

Frontend Vue/Vite
    -> Supabase Auth, when configured

Scraper
    -> PostgreSQL

SIEC follows a modular architecture where the frontend handles the interactive editor, visualization, dashboard, analytics, and settings experience. The backend is responsible for API logic and data workflows. PostgreSQL supports structured persistence, while the scraper module can be used to prepare or update external pricing data.

Quick Start

Clone the repository

git clone https://github.com/Raizexs/SIEC.git
cd SIEC

Run with Docker

docker-compose up --build

Before running Docker, copy .env.example to .env and set SERPAPI_METALCON_API_KEY if you want live Metalcon search results.

Run the frontend manually

cd frontend
npm install
npm run dev

Run the backend manually

cd backend
pip install -r requirements.txt
uvicorn main:app --reload

Environment configuration depends on the module being executed.

Project Status

SIEC is currently in beta / advanced prototype stage.

The main product experience, including the workspace, layout flow, visual editor, project dashboard, analytics, and settings modules, is under active development. Some integrations, export workflows, and external pricing sources may still be evolving.

Roadmap

Short Term

• Connect product preferences directly to the editor and estimation flow.
• Improve PDF, IFC, and GLB export behavior.
• Refine base templates and saved layout management.
• Strengthen visual QA across dark and light modes.

Medium Term

• Integrate real pricing APIs and structured cost sources.
• Add customizable commercial reports.
• Improve version history and project recovery.
• Expand project analytics and risk detection.

Long Term

• Advanced BIM integration.
• Multi-user collaboration.
• Cloud synchronization.
• Predictive cost analysis.
