Measurement & Deliverable Parameters
How are Cardiff commercial packages measured and delivered?
| Estimating Parameter | Technical Specification | Standard / Audit Basis |
|---|---|---|
| Measurement Section & Units | NRM2 Commercial Tender Packages measured in m2, m, nr, m3, item | Scaled GA plans at 1:50 / 1:100 or structural details in mm |
| Local Statutory Framework | Building Regulations (Wales) Approved Documents & Welsh SuDS SAB Mandatory Drainage Approval | Wales statutory & local tender compliance notes |
| Wastage & Prelim Separation | Net quantities isolated with 5%–10% typical trade waste allowances | Cardiff logistics and phased delivery allowances |
