Online Tender Portal
PX4 Tender Management Portal
The Challenge & The Solution
PX4 was engaged by a major governmental body to transform a critical resource licensing process into a modern, secure, and fully digital platform. We delivered a secure, GIS-based online tender platform for mineral exploration licensing, built entirely on Google Cloud Platform (GCP) using a serverless architecture.
Welcome to the Portal
Project Scope & Objectives
| Key Objective | Strategic Outcome |
|---|---|
| User Experience | Develop a user-friendly, fully digital tendering platform for exploration block licensing. |
| Custom Integration | Integrate with Taadeen.sa and custom GIS features for block allocation. |
| Tender Mechanics | Deliver a multi-round tender engine with real-time transparency and configurable parameters for spend, duration, and rounds. |
| Security & Auditing | Ensure ISO and GDPR compliant security, logging, and auditing. |
| Performance & Scalability | Build on serverless GCP infrastructure to achieve scalability, performance, and minimal maintenance overhead. |
Specific Outcomes & Operational Improvements
Core System Capabilities
End-to-end digital tendering
digitised the full workflow for exploration tenders.
Automated multi-round logic
configurable exploration spend increments and timed rounds.
Interactive GIS map interface
bidders select and compete on mineral blocks in real time.
PQQ (Prequalification) engine
reusable templates, document uploads, and pre-stored bidder data.
Key Functional Improvements
Serverless scalability
auto-scales on demand, removing the need for fixed VMs or manual scaling.
Real-time auction transparency
Ensuring fairness, trust, and accountability throughout the auction lifecycle.
Security compliance
encryption in transit and at rest, ESNAD audit-ready controls, GCP IAM.
Operational efficiency
lower cloud costs, simplified maintenance, and higher uptime.
How It Works
Platform Architecture & Technical Foundation
| Component | Technical Details |
|---|---|
| Architecture | 100% Serverless on Google Cloud Platform (GCP) |
| Core Services | Cloud Run – containerised API and frontend services Cloud Functions – automated processes for bidding, notifications, and PQQ validation Cloud SQL (serverless) – managed relational database Cloud Storage – tender and document management Cloud IAM & Auth0 – access control and authentication |
