Spec it in.
ASSE 1072-2020
BIM ready

The designer of a new hotel, hospital, or plant must specify floor drains and control measures. Compliance with ASSE 1072-2020 and EN 1253 is required for building certification. We provide specification sheets ready for inclusion in the cost estimate—no time wasted.

Problem & solution

What do you need? to be in the expense account.

The main water supply and sewerage project specifies a P-trap in accordance with EN 1253. The architect or MEP designer is requesting models with specific parameters, certificates, and an SDS for inclusion in the cost estimate.

Without Green Drain™

  • Without compliance with ASSE 1072 — subsequent revisions require documentation.
  • EN 1253 compliance — covers most European traps
  • BIM (Revit/ArchiCAD/Allplan) typically requires a model and specifications.
  • EU MDR Class I — if the facility is healthcare, the designer must specify the device.
  • The prime contractor is requesting availability—delivery time and price on request.

With Green Drain™

  • PDF specification by size (GD 1.25 to GD 6) — ready for the cost estimate
  • BIM template for Revit, ArchiCAD, Allplan — inserted into the model
  • Declarations of Conformity, SDS, and Certificates — one ZIP
  • ASSE 1072-2020 report — covers American standards for EU projects
  • Technical support in English — same-day response from Dublin
Standards and Chambers

EU standardization is becoming stricter.

RIAI (Royal Institute of the Architects of Ireland), Engineers Ireland, CIBSE Ireland and the BRegs / TGD-Part B,G,J framework. Cross-referenced into BIM workflows on Revit, ArchiCAD and Allplan. EN 1253 is part of nearly every M&E execution package.

Implementation

Procedure through project

We send a package of documentation upon request. The designer includes the conceptual, schematic, and detailed design phases.

01

Request

Send the object type and project scope — we'll send the documentation package.

02

Conceptual design

Spec in the concept phase — we help with size selection.

03

Master plan

BIM model and PDF spec to the bill of quantities.

04

Performance

The prime contractor orders through us—delivery according to the work schedule.

Model Recommendation

Specification per project type

Designers receive the complete Green Drain™ line (11 SKUs) in BIM format (Revit, ArchiCAD, Allplan, Bentley). LOD 300 is sufficient for the construction project. For healthcare facilities, an additional MDR Class I documentation package. Tender specifications are prepared with references to ASSE 1072-2020 and EN 1253.

Green Drain™ Recommended for your industry.

  • Hospital / clinic — GD 2 (dominant), GD 3 (ICU), GD 4–5 (OR, kitchen), GD 5–6 (central). MDR Class I documentation.
  • BC Building (office tower) — GD 2 (sanitary facilities), GD 3 (cafeteria), GD 4–5 (garages). LEED/BREEAM contribution.

Questions

Most common doubts

In which format do you send the BIM files?

Revit (.rfa), IFC (universal), ArchiCAD (.gsm/.lcf) and Allplan. LOD 300 is sufficient for the construction project. We also send a PDF cut-sheet to size.

And for healthcare facilities (HSE acute hospitals)?

We are sending an additional package: EU MDR Class I declaration, EUDAMED registration, compatibility with hospital disinfectants, and technical dossier for compliance with the Medical Devices Directive.

Price for the cost estimate?

We send current entry prices by size and quantity. EU-registered supplier — no customs delays for Irish or EU customers.

Complete solution

Three products.
One protection portfolio.

Green Drain™ doesn't work alone — for maximum drain control it's combined with GD Uri-Tabs™ (urinals) and GreenSwirl™ (biofilm bio-cleaning).
