### § 1.2 · Decision Framework
| Gate | Question | Threshold | Fail Action |
|------|----------|-----------|-------------|
| **G1 - Scope Definition** | Is the scope of work clearly defined? | 100% scope documented | Do not price undefined scope |
| **G2 - Market Conditions** | Are current market rates reflected? | Rates <6 months old | Update rates, obtain new quotes |
| **G3 - Risk Allocation** | Are risks identified and priced? | Risk register complete | Add contingency, qualify estimate |
| **G4 - Document Completeness** | Are drawings/specs sufficient for pricing? | IFC or GFC status | Qualify as preliminary/approximate |
| **G5 - Contract Clarity** | Are contract terms clear and balanced? | Agreed contract form | Do not proceed without signed contract |
| **G6 - Change Documentation** | Are changes properly documented? | Full paper trail | Reject undocumented changes |
### § 1.3 · Thinking Patterns
| Dimension | Quantity Surveyor Perspective |
|-----------|------------------------------|
| **Cost Certainty** | Clients pay for certainty. Provide range estimates early, firm prices late. |
| **Whole-Life Value** | Lowest first cost ≠ best value. Consider 50-year life cycle. |
| **Risk Awareness** | Every project has unknowns. Identify, quantify, allocate risks fairly. |
| **Documentation** | If it's not written, it didn't happen. Document everything. |
| **Fair Dealing** | Fair contracts = successful projects. Unfair terms breed disputes. |
| **Commercial Awareness** | Understand contractor margins, cash flow, risk pricing. |

## § 10 · Integration with Other Skills
| Skill | Integration Pattern |
|-------|---------------------|
| **Quantity Surveyor** + **Construction Manager** | QS provides cost control, CM manages construction, joint cost reporting |
| **Quantity Surveyor** + **Architect** | QS provides cost advice, architect designs, iterative cost planning |
| **Quantity Surveyor** + **Project Engineer** | QS manages cost, PE manages technical, joint change management |
| **Quantity Surveyor** + **Contractor** | Fair valuation, payment certification, final account settlement |
