Measurement & Deliverable Parameters
How are Southampton waterproofing packages measured and delivered?
| Estimating Parameter | Technical Specification | Standard / Audit Basis |
|---|---|---|
| Measurement Section & Units | BS 8102 Type A/B/C Structural Waterproofing measured in m2, m, nr | Scaled GA plans at 1:50 / 1:100 or structural details in mm |
| Local Statutory Framework | Building Regulations (Approved Documents Parts A–S) & Building Safety Act (BSA) Gateways 1–3 | England statutory & local tender compliance notes |
| Wastage & Prelim Separation | Net quantities isolated with 5%–10% typical trade waste allowances | Southampton logistics and phased delivery allowances |
| Deliverables & Drawing Uploads | 100% open-formula Excel BoQ + colour-coded PDF overlays (up to 25 MB upload) | 24–48 hrs turnaround target for focused single-trade packages |
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.
What is measured in every Southampton pack?
UK basements, lift pits, and podium slabs carry strict BS 8102 Grade 3 habitable criteria where omitting one service-penetration collar or perimeter drainage channel causes expensive leaks. Our CSSW-style measurement covers full triple/dual combined systems.
- Separates vertical retaining wall tanking (plus 500mm floor/ceiling laps), lift shaft pit linings, and podium inverted waterproofing.
- Captures sump pump stations, dual battery backups, high-water alarms, and inspection rodding eyes.

Waterproofing Estimating FAQs for Southampton
How does Southampton site context influence waterproofing estimating takeoffs?
Port-adjacent arterial roads alongside nutrient-neutrality coastal drainage and SUDS attenuation rules. Alongside Separates vertical retaining wall tanking (plus 500mm floor/ceiling laps), lift shaft pit linings, and podium inverted waterproofing. Our Excel workbooks separate measured quantities cleanly from site-specific prelim and access allowances.
Which file formats can Southampton contractors upload for a waterproofing quote?
Upload scaled PDFs, DWG/DXF CAD files, Revit/IFC BIM models, or NBS specifications directly via our online tender desk—every waterproofing estimating pack returns editable Excel schedules and marked-up PDF sheets.
Can you measure combined Type A + Type B + Type C BS 8102 systems on one basement?
Yes. Type A external liquid/sheet membranes, Type B integral waterstops at day joints, and Type C internal cavity drained membranes/channels are itemised in clear layers.
