A swim spa is easy to forget in a villa or resort schedule. It arrives late in the design process, gets quoted as a stand-alone purchase, and only then does somebody ask where the power comes from, who pours the base, and how a 5.5 metre shell gets through the gate. Treating the Outdoor Swim Spa WS-125AⅢ-U as one line in a full materials schedule, rather than a last-minute accessory, is what keeps the pool deck, the outdoor furniture, the pergola, the paving and the wet services speaking the same language.

Start from the footprint, not the brochure

Catalogue dimensions for the WS-125AⅢ-U are 5500 × 2300 × 1350 mm. Those three numbers drive the civil works before anybody chooses a tile: the excavation or plinth, the drainage around the shell, the width of the access route, and the clearance needed for the steps and for the plant that sits behind the cabinet. In a whole-project schedule this is the first entry to lock, because paving edges, retaining lines and the setting-out of the outdoor furniture zone all reference it.

Write the entry the way the builder needs to read it: model code, overall dimensions, the position of the plant and access panel, the load path, and the party responsible for the base. A line item that only says "swim spa, as per design" transfers the whole coordination risk to site.

Record the equipment set that was actually selected

The published specification for this configuration lists one control system, four water pumps, one filter pump, a jet total of 23 pieces and one LED light, with a total power figure of 11.85 kW; the swim training system is not listed for the -U variant. Water jets, LED lighting and ozone are the features shown on the product page.

Do not copy that block into a schedule as a fixed guarantee. Santerson's outdoor swim and hydrotherapy range is configurable, and optional items such as control systems, UV sterilisation, water pumps, heat pumps, sand filtration, insulation and steps change both the bill of quantities and the electrical load. The honest schedule entry states the base configuration, then lists the options that were priced for this project, so the electrical contractor, the hydraulic engineer and the procurement team are all buying against the same document.

Schedule the power and control as a separate trade line

The total power figure is where most swim spa schedules fail, because it is not an appliance plug. An installation in this band needs a dedicated circuit, a distribution position close to the plant, protection and earthing designed by the local electrical engineer, and a decision on where the control system is mounted and whether it is operated from the deck or from a wall panel. Put those items in the electrical section of the schedule with the spa model code cross-referenced, and confirm the incoming supply requirement with the manufacturer for the exact configuration before the first fix.

The same logic applies to water and heating. Filtration and ozone are treatment items with their own consumption points; a heat pump, if selected, brings its own position, noise separation and condensate question. Each of these should appear as its own row so it cannot fall between two trades.

Coordinate the swim spa with the rest of the outdoor package

A spa used as part of a hospitality or villa outdoor room sits inside a larger material set: furniture and building materials for the surrounding deck, hardtop structures that shade it, wall and ceiling finishes on the adjacent faces, and flooring that runs up to the coping. When one supplier carries several of those categories, the schedule gains a single point of contact for dimensions, finishes and delivery windows. Where categories come from different sources, the schedule needs to state clearly who is responsible for the interface, because the coping detail is exactly where disputes start.

Delivery sequencing belongs in the same document. A spa shell and its plant cannot be lifted across a finished deck or through a completed structure, so the delivery date has to precede the permanent enclosure of the outdoor area. A schedule that lists lead times by trade, with the spa's production time noted, gives the programme a chance of holding.

Specify what you want confirmed before order

Before any purchase order is raised, ask for written confirmation of the configuration: the pump and jet set, the treatment package, the lighting count, the options included, the electrical requirement, the base and support detail, the step arrangement and the packing list. For a project being shipped internationally, add packaging, container loading, the shipping terms for the shipment and who handles installation and commissioning on site. Santerson's service scope covers custom and OEM work, logistics and door-to-door delivery, and installation and after-sales support, so those responsibilities can be assigned in writing rather than assumed.

A practical schedule entry

A workable line for a materials schedule reads: item number, product name and model code, link to the product page, catalogue dimensions, selected configuration with options listed, power requirement as confirmed for that configuration, responsibility for base and power, delivery window and access route, and the interface details for coping, paving, steps and control position. That single row, written once in the design stage, answers the questions that normally surface as variations on site.

For a project that needs the spa, the deck furniture, the shading structure and the interior fit-out specified against the same programme and the same document set, send the model code and the drawings to SANTERSON and have the configuration confirmed before the tender packages are issued.
