How does bid tabulation work?

When the deadline passes, all submitted bids compile into a tab showing each bidder's base bid and alternates in columns. The system highlights the low bidder for each line item. Adjustments and award selections are made by the owner.

What are alternates and unit prices?

Alternates are optional scope additions or deductions. Unit prices are per-unit rates for variable quantities. Both are collected alongside the base bid, giving owners flexibility in determining the award scope.

How are clarifications managed?

Bidders submit questions through the portal. Public questions receive responses published as addenda to all bidders. Private questions with proprietary information are answered only to the submitting bidder.

The Challenge

Why building a Construction Bid from scratch is hard

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

What's Included

Everything your Construction Bid needs

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

Project specification document distribution to bidders

Bidder pre-qualification and invitation management

Bid package creation with scope and templates

Online bid submission with price breakdown

Bid tabulation and comparison

Leveling and clarification RFI management

Award workflow with letter of intent

Bid archive for market intelligence

Architecture

How it's built

The generated Construction Bid follows production-grade architecture patterns.

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

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

PostgreSQL relational schema with normalized tables for all construction bid entities

JWT + Google OAuth authentication with granular permission gates per role

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

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

Database

PostgreSQL schema designed for Construction Bid

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.

bid_packages (id, project_id, scope_description, plans_url, submission_deadline, status, workspace_id)
bidders (id, company_name, contact jsonb, license_number, prequalification_status, categories jsonb, workspace_id)
bids (id, package_id, bidder_id, base_bid, alternates jsonb, unit_prices jsonb, submitted_at, status)
bid_clarifications (id, package_id, bidder_id, question, response, is_public, created_at)
