Case Study: Unit Ventilator, Roofing & Ceiling Works – Central School Building (Phase 1) | True Bid Data

Scope of Services

Preparation of civil and architectural quantity take-offs and bid support using PlanSwift for Phase 1 of the 2024 Capital Project. The scope included architectural works associated with unit ventilator replacement, roof replacement, and ceiling demolition and reinstatement, with quantities separated for the Base Bid and three alternates and updated through four addendums.

Project Complexity

The project involved renovation within an operational school facility subject to NYSED public-sector requirements. Complexity arose from multiple addendums, three alternates, and the need to distinguish architectural enabling works from mechanical scope.

Key Issues Encountered:

Several quantities were not fully defined in the drawings, particularly for localized demolition and ceiling replacement extents. Addendum-driven revisions required repeated re-measurement and reconciliation of quantities.

Approach

Detailed PlanSwift take-offs were prepared using architectural, demolition, and reflected ceiling plans. Where quantities were unclear, reasonable engineering assumptions were applied and documented. Quantities were clearly segregated by base scope, addendums, and alternates.

Outcome

The final take-off supported a clear and compliant bid submission, reduced scope ambiguity, and demonstrated effective quantity management for a NYSED-regulated school renovation project.
