Context-Based Access Control (CBAC) for Construction

Define dynamic permissions by role, job title, company, and project context. Protect sensitive information and ensure teams access only what they need for their work.

What is CBAC in construction?

CBAC (Context-Based Access Control) is a permission model that considers not only user role, but also company, job title, project, and specific context. In multitenant construction with multiple companies, CBAC ensures subcontractors see only their tasks, GC controls confidential documents, and each user accesses only relevant information.

Common construction permission challenges

• Overly broad permissions: subcontractors see confidential information from other companies

• Overly restrictive permissions: teams cannot access documents or tasks they need

• Manual permission management that does not scale: adding users or changing roles generates repetitive work

• Without context: permissions do not consider company, project, or phase, generating inappropriate access

How CBAC works in Modunex

1. Permissions by role, job title, and company

Define base permissions by role (PM, supervisor, engineer) and refine by job title and company. Subcontractors see only their tasks and documents, GC controls full access as needed.

2. Contextual control by project and phase

Permissions vary by project and execution phase. User may have full access in Project A and limited access in Project B. CBAC adjusts access dynamically based on context.

3. Dynamic and scalable rules

Configure rules once and Modunex applies them automatically to new users and projects. Changes in roles or companies update permissions without repetitive manual intervention.

Why context-based access control matters

Construction projects involve multiple companies (GC, subcontractors, consultants) with different access needs. Without CBAC, confidential information leaks or teams cannot work due to lack of access.

CBAC protects sensitive data, ensures compliance, and enables smooth collaboration between companies without exposing unnecessary information. Teams work with precise access based on their context.

Who benefits from Modunex CBAC?

Project managers (GC): Control who accesses confidential information and ensure compliance in multitenant projects

System administrators: Configure scalable rules that apply automatically without repetitive manual management

Subcontractors: Access their tasks and documents without seeing information from other companies, working with precise context

Legal and compliance teams: Ensure permissions comply with regulations and protect sensitive data by company and project

Control access with precision

Move beyond rigid or nonexistent permissions. Implement CBAC to protect information and provide proper access based on each user's context.
