Construction Company Automation System(AI+ make.com

Hello,
I am looking for a developer / automation specialist (or a small team) to build a full construction company management system for UAB Statnamis (Lithuania). The goal is to automate construction operations “from A to Z” using Make.com or n8n, Google Drive/Google Sheets/Gmail, and AI integration (ChatGPT / OpenAI API).
The system should include:
1) Project / Site Management
Manage multiple construction sites/projects at the same time
Daily worker reports (progress tracking)
Photo uploads (before/after, daily progress)
Completed quantities (m² / m / pcs)
Issues reporting (electricity not disconnected, structural support needed, missing approvals, etc.)
2) Material Tracking (Per Project)
Material delivery tracking
Material usage tracking
Remaining material stock on site
Weekly/monthly material summary reports
3) Fuel Tracking (Per Vehicle/Machine/Project)
Fuel input records (liters, date, machine/vehicle)
Fuel summary per project and per machine
Automatic weekly/monthly fuel reports
4) Health & Safety + Fire Safety Documentation Tracking
Track employee safety trainings, certificates, permits, medical checks, etc.
Track fire safety documents (fire extinguisher inspections, permits, hot work permits, etc.)
Automatic reminders before expiration (30/14/7 days + expired status)
5) Document Management System
Automatic Google Drive folder structure for each project
Document registry in Google Sheets (contracts, invoices, work acts, estimates, safety documents, etc.)
Easy search and organized archive
6) Automatic Work Acts Generation (Weekly or Bi-Weekly)
Automatically generate work completion acts (Word/PDF template)
Include completed quantities, photos and work descriptions
Automatic numbering and project identification
Automatically send acts by email to the main contractor
Automatically save to Google Drive
7) Email → Google Drive Automatic Sorting (IMPORTANT)
Automatically monitor incoming emails (Gmail or Hostinger email forwarded to Gmail / IMAP)
Detect and download attachments (contracts, invoices, acts, safety documents, etc.)
Automatically sort attachments into correct Google Drive folders per project:
Invoices
Work Acts
Contracts
Safety (H&S)
Fire Safety
Automatically rename files and create a record in Google Sheets registry
8) AI Contract Analysis (Optional but Preferred)
AI reads PDF/Word contracts
Detect risky clauses (penalties, deadlines, responsibilities, payment terms, additional works)
Generate a risk report (score 1–10) and recommendations
9) AI Estimating / Tender Pricing System (VERY IMPORTANT)
The system must be able to generate construction estimates (Excel/Google Sheets) based on:
tender documentation (PDF, Word, BOQ tables)
project specifications
quantities and work descriptions
Estimates must be calculated using Lithuanian market pricing and my own company pricing database (provided as Excel/Google Sheets):
labor rates
machine hourly rates
material rates
overhead and profit margins
VAT calculation
The system should generate:
full estimate table (Excel/Sheets)
final tender price summary
commercial offer (PDF/Word template)
Preferred Technology
Make.com or n8n automation platform
Google Drive / Google Sheets / Gmail
OpenAI API integration (ChatGPT)
Document generation using Google Docs / Word templates
Project Requirements (IMPORTANT)
All automation scenarios must be built inside my own accounts (Make.com, Google Drive/Workspace).
Full access must be provided after delivery.
Full documentation must be provided so another developer can maintain the system if needed.
Please Provide:
Price estimate in stages (MVP + full system)
Timeline for each stage
Monthly support/maintenance cost after delivery
Examples of similar automation/AI projects
Communication can be in English. Documentation can be prepared in Lithuanian if needed.
