Bâti

Project Overview

Bâti is a site-management platform that gives construction companies one source of truth for every project. Site managers track progress against the plan, log dated photos of the work, assign tasks to trades, and get alerted the moment a delay or a reserve appears — instead of discovering it at the weekly meeting.

Client Challenges

• Progress was tracked in spreadsheets and email threads; nobody had a clear view of where each site stood.
• Photos and observations lived on phones and WhatsApp, impossible to date-stamp or sort.
• Delays and reserves surfaced too late, when re-planning was already expensive.
• Coordinating trades and deliveries relied on calls and paper notes.

Our Solution

• A project dashboard with global progress, milestone planning (Gantt) and budget tracking per site.
• Dated progress photos attached to each phase, so site managers and clients see real advancement.
• Task assignment to trades with statuses, and alerts (reserves, late deliveries) surfaced immediately.
• Daily interventions view for the teams on site — who works where, and when.

Key Features

• Global progress: overall %, milestone bars and delivery dates per site.
• Progress photos: dated shots per phase, attached to the timeline.
• Milestone planning: Gantt-style view of foundations, structure, roof, finishes.
• Tasks & reserves: assign, track and flag corrective work.
• Alert center: delays, reserves and confirmations in one feed.

Tech Stack

• Backend: Next.js (React) · ORM: Prisma · Database: PostgreSQL
• Media: photo upload + storage on Cloudflare R2 (with thumbnails)
• Planning: custom Gantt/schedule component
• Notifications: SMS + email + WhatsApp for teams and suppliers
• Auth & roles: site manager, trades, client views

Results & Impact

• −58 % time spent on weekly status reporting.
• +41 % faster detection of delays (average), allowing re-planning before costs spike.
• 100 % of phases tracked with dated photos — no more “what was done when”.
• 2× more sites managed by the same site-management team.
• −37 % missed deliveries thanks to alerting on supplier schedules.

“I see every site on one screen, with photos that prove the progress. We catch delays days earlier now.” — Site manager, Bâti
