Truss shop drawing review: Budgeting and cost control — RiverTruss educational resource

Why this matters

Shop drawings communicate the engineered truss geometry and project-specific requirements; review is about coordination and completeness, not replacing the engineer of record. A useful budget separates known costs, allowances, contingencies, and decisions that can still change the outcome.

Approving a shop drawing with unresolved plan conflicts transfers avoidable risk into the field.

A practical framework

  1. compare layout with architectural and structural plans
  2. check openings, girder trusses, and bearings
  3. review notes, reactions, and bracing information
  4. record questions before fabrication

Questions to answer

  • Which cost is supported by a quote, and which is still an allowance?
  • What event would consume the contingency, and how would it be approved?
  • Which scope decision creates the largest downstream cost if delayed?

Common failure modes

  • Comparing two budgets that use different scopes or assumptions.
  • Hiding uncertainty inside a single optimistic total.
  • Treating a low first cost as proof of a low total cost.
