Introduction
Tender drawings are the foundation of every successful facade project. Whether you're pricing a rainscreen cladding system, curtain wall, fibre cement panels, or metal composite panels, the ability to accurately interpret tender drawings directly impacts the quality of your estimate.
Many contractors focus only on architectural elevations, overlooking critical information hidden within sections, specifications, schedules, and detail drawings. Missing these details can result in inaccurate quantities, unexpected costs, and reduced profit margins.
This guide outlines a structured approach to reviewing facade tender drawings like an experienced estimator.
Step 1: Start with the Drawing Register
Before reviewing any drawings, confirm that you have the latest revision of every document.
A typical facade tender package includes:
Architectural GA Drawings
Elevations
Floor Plans
Building Sections
Facade Details
Window and Door Schedules
Specifications
Structural Drawings
Fire Strategy Drawings
Working from outdated revisions can invalidate an entire estimate.
Step 2: Understand the Scope of Work
Identify exactly what is included in your tender package.
