===================================== Section 10 28 13 : Toilet Accessories ===================================== Supplementary item: retractable child step stool, floor anchored Text ready to drop into the design consultant's terms of reference, and later into the construction specification. Adjust quantities, locations and colours to suit the project. Articles 2.4 and 2.5 are written in performance terms and provide an equivalence route , so the item can be specified without restricting competition or favouring any supplier. 1 General 1.1 Section includes Supply and installation of retractable step stools that allow a child to reach a washroom sink unaided, with no change to the plumbing, no lowering of the basin and no second set of fixtures. 1.2 Design intent Make handwashing independent for children aged 2 to 8 while keeping the sink at standard adult height for staff, visitors and caregivers. The step folds back on its own after each use: no loose furniture is left in the room, and the floor stays clear for circulation, for wheelchair manoeuvring space and for cleaning. 1.3 Submittals - Manufacturer's data sheet for each model proposed, including dimensions and projection from the counter. - Shop drawings or CAD and Revit files showing layout, clearances and anchoring details. - Manufacturer's installation guide. - Colour sample or selected RAL reference. 1.4 Warranty Manufacturer's warranty against defects in manufacture: five (5) years on the aluminum model, including the retraction mechanism; three (3) years on the steel and removable models. 2 Products 2.1 Reference product Retractable child step stool, Klimbo K01, K02 or K03, manufactured by Groupe Klimbo Inc.

The professional of record reviews the request against Article 2.4 alone. This article exists so that naming a reference product does not restrict competition. 3 Execution 3.1 Installation Install to the manufacturer's guide, into the concrete slab, using the drilling template supplied. Provide clear floor space in front of the sink matching the projection of the deployed step, outside the manoeuvring space required for a wheelchair. Verify full retraction after installation. 3.2 Coordination with an accessible lavatory Where a lavatory is required to be accessible (ADA 2010, 213.3.4), do not install the unit within the knee and toe clearance (ADA 2010, 306) or the clear floor space (ADA 2010, 305.4, 606.2) of that lavatory; provide it at another lavatory in the same room. Coordinate the location with the lavatory, counter and required clearances shown on the drawings before rough-in. 3.3 Recommended locations - At least one step stool in every washroom serving children and youth, on both the girls' and the boys' side. - In the universal or family washroom where one is provided, and at the sink nearest the entrance. - At sinks in any public washroom serving the community or family spaces of the building. 3.4 Maintenance Clean with standard sanitary products; no lubrication required by the operator. Automatic retraction leaves the floor fully clear for washing. 3.5 Note to the design consultant A public sink sits at a height standardised for an adult: between the ages of 2 and 8, a child does not reach it alone. Written into the scope at the design stage, the step stool integrates with the millwork and the finishes; added after the work is complete, it becomes a loose stool that sits in the circulation path.
