Tender Delivery Standards

Quantity Surveying Workflow

How technical blueprints and engineering drawings are transformed into accurate, deadline-driven tender submissions.

01

Blueprint Analysis & Take-Off

Reading structural/civil drawings, importing CAD/PDFs into PlanSwift, and establishing accurate digitized linear, area, and volumetric measurements.

02

BOQ & Rate Itemization

Structuring standardized Bills of Quantities in Excel, conducting unit rate analysis, and organizing line items according to strict specifications.

03

AI Audit & Bid Support

Integrating AI-assisted auditing workflows to cross-verify measurement accuracy, detect discrepancy risks, and deliver deadline-driven tender outputs.

Precision Pavement Zoning

The Challenge: Complex site layout requiring rapid categorization of 5 distinct pavement load capacities under a strict tender deadline.
The Solution: Digitized the Site Grading Plan in PlanSwift, applying custom color-coded polygon zoning to isolate block paving, heavy RTG beam reinforced concrete, and roadway areas.
The Impact: Eliminated manual measurement overlap and delivered an audited, tender-ready BOQ 100% on schedule.
