Substructure & Ground
How does Glamorgan (Cardiff & Swansea Corridor) geology affect substructures?
Coastal mudflats, Coal Measures Valley profiles, and limestone cliffs demanding Welsh SAB SuDS storage.
Wales (Cardiff, Swansea & Regional) · Wales
Bay-area mixed commercial blocks, student/residential towers, industrial light engineering units, and terraced refurbishments.
Substructure & Ground
Coastal mudflats, Coal Measures Valley profiles, and limestone cliffs demanding Welsh SAB SuDS storage.
Site Prelims & Freight
Welsh SAB surface-water regulation makes permeable sub-base & attenuation crate lines essential on almost all sites.
Conservation & Fabric
Pennant stone walls, Welsh slate pitched roofs, and high-exposure wet-dash rendered assemblies.
Measurement & Deliverable Parameters
| Estimating Parameter | Technical Specification | Standard / Audit Basis |
|---|---|---|
| Applicable Standards | Building Regulations (Wales) Approved Documents & Welsh SuDS SAB Mandatory Drainage Approval | Applied alongside Glamorgan (Cardiff & Swansea Corridor) planning & material expectations |
| Drawing Scales & Units | 1:50 & 1:100 GA plans calibrated independently in mm, m, m2, m3 & t | Every line linked to drawing sheet reference and structural grid |
| Wastage & Prelim Split | 5%–10% typical trade waste isolated from net quantities | Welsh SAB surface-water regulation makes permeable sub-base & attenuation crate lines essential on almost all sites. |
| Deliverable Format | 100% open-formula Excel + colour PDF check drawings (24–48 hr target small jobs) | Upload files up to 25 MB through our UK tender portal |
Calibration note: 1:50 and 1:100 architectural and structural drawings are scaled to 25 mm masonry tolerances and 100 mm thermal zones, isolating 5 percent to 10 percent wastage from net quantities.
County Procurement & Takeoffs
Projects throughout Glamorgan (Cardiff & Swansea Corridor) (Wales (Cardiff, Swansea & Regional)) fall under Building Regulations (Wales) Approved Documents & Welsh SuDS SAB Mandatory Drainage Approval. Public estates frequently utilise NEC4 frameworks alongside JCT Standard/D&B forms in Cardiff, Swansea, Newport, and Wrexham. Our digital takeoffs supply contractors, developers, and specialist trade subbies with editable Excel Builders Quantities, separated waste factors, marked-up PDF drawing sets, and RFI schedules covering missing construction details.
Coastal mudflats, Coal Measures Valley profiles, and limestone cliffs demanding Welsh SAB SuDS storage. Our schedules itemise trench widths, concrete grades, haulage spoil disposal, and shoring separately from standard superstructure works.
Pennant stone walls, Welsh slate pitched roofs, and high-exposure wet-dash rendered assemblies. Every material schedule pairs net drawing quantities with explicit specification notes matching your architect's elevation and section details.
Upload scaled PDF plans, DWG/DXF CAD files, Revit/IFC models, or NBS specifications (up to 25 MB per upload). Finished packs issue in open-formula Excel with colour-coded PDF overlays.
