How does the RFI workflow work?

When the field team encounters an unclear specification, they submit an RFI with a question and supporting drawings. The system routes it to the architect/engineer with a response due date and tracks open RFIs and average response time.

How are change orders managed?

When scope changes, the superintendent creates a change order with cost and schedule impact. The PM reviews and packages it for the client/owner. On approval, the contract value and schedule are updated automatically.

Can subcontractors submit their own progress?

Yes. Subcontractors have a portal login where they submit daily logs, percentage complete updates, and requisition for payment. GCs review and approve before payment processing.

The Challenge

Why building a Construction ERP from scratch is hard

Building a Construction ERP Platform from scratch requires months of development time and significant engineering resources. Teams struggle to coordinate frontend, backend, database, and authentication while managing construction erp-specific business logic, integrations, and role-based access rules.

What's Included

Everything your Construction ERP needs

ProjectCode generates a production-ready Construction ERP with all the modules your team needs from day one.

Project management with WBS, milestones, and Gantt chart

Subcontractor management and bid comparison

Cost code-based budget tracking and job costing

Daily construction log and photo documentation

RFI (Request for Information) and submittal management

Change order workflow with owner approval

Equipment and tool tracking with utilization reporting

Payroll integration for field workforce time

Architecture

How it's built

The generated Construction ERP follows production-grade architecture patterns.

React 18 + TypeScript frontend with role-based dashboards tailored for construction erp workflows

NestJS REST API with dedicated construction erp modules, DTOs, validators, and service layer

PostgreSQL relational schema with normalized tables for all construction erp entities

JWT + Google OAuth authentication with granular permission gates per role

Real-time Socket.IO events for live construction erp status updates and notifications

Managed hosting with one-click deploy, custom domain, and auto-SSL

Database

PostgreSQL schema designed for Construction ERP

ProjectCode generates a normalized, indexed PostgreSQL schema with the right tables and relationships for your use case. You own the schema and can evolve it freely.

projects (id, name, client_id, address, type, contract_value, start_date, end_date, status, superintendent_id)
cost_codes (id, project_id, code, description, budget, actual_cost, committed_cost, forecast)
rfis (id, project_id, number, subject, submitted_by, submitted_at, due_date, response, status, days_open)
change_orders (id, project_id, number, description, cost_impact, schedule_impact, status, approved_by, approved_at)

FAQ

Common questions about building a Construction ERP

Job costing tracks all costs (labor, materials, subcontractor, equipment) against specific cost codes for each project. Comparing actual costs to the budget in real time lets project managers identify cost overruns before they become critical.
