Grade-2 Cost Engineer (China) cheat sheet

Integrated built-environment foundations

• Define scope and measurement rules before calculating or pricing.

• Distinguish markup, margin, cash movement and expense.

• Use dependencies and real prerequisites when reviewing a schedule.

• Separate measured work from contractual entitlement.

• State the system boundary and assumptions before calculation.

• Units, sign conventions and uncertainty are part of the answer.

• Verification against a specification differs from validation for an intended use.

• Drawings need a declared convention and controlled revision.

• Classroom models do not authorize physical operation or structural approval.

• R=d/λ uses thickness in metres; total resistance includes the model’s surfaces and layers.

• U=1/R_total is a steady-state element model, not the complete building energy demand.

• Permanent, occupancy, wind and snow actions require the stated design framework.

• Moisture, airtightness and intended ventilation must be considered together.

• Example tie spacing is supplied data, not a code rule.

• Clarify actual responsibility, approved drawings and change authority.

• Hazards require task-specific controls, not one universal PPE recipe.

• Inspect concealed requirements before they become inaccessible.

• Separate net quantities, stated allowances and unresolved handover issues.
