The starting line of a raised floor influences almost every panel along the room perimeter. For a Colombia office project, approve the grid using the surveyed space and coordinated service layout before finalising the panel order. A room area alone cannot show narrow cuts, awkward outlet positions or conflicts beside columns.
Setting-out is a practical coordination exercise. The goal is a buildable layout that supports the panels correctly, preserves access and makes installation quantities traceable.
Work from the surveyed room
Record actual wall positions, columns, recesses, doorways and fixed equipment bases. Confirm whether the walls are square and whether the drawing dimensions match the site. Note the floor datum and any level changes that affect the layout.
Use a stable project reference for the grid origin. An installer should be able to recover the same starting point from the approved drawing after other trades have worked in the room. Avoid relying on a temporary mark that may disappear during preparation.
Compare alternative grid origins
Moving the origin can redistribute perimeter cuts and alter how the grid meets doors or columns. Compare at least the practical alternatives where the room geometry creates difficult edges. Ask the system supplier to review the proposed cut-panel dimensions and supports; there is no universal minimum cut size suitable for every system.
For illustration, a surveyed width of 6.5 m does not divide evenly into a 600 mm module. Ten full modules account for 6.0 m, leaving 0.5 m to resolve in the chosen arrangement. Placing the entire remainder at one side or distributing cuts differently changes the edge details. This arithmetic is a layout prompt, not an approval of any particular cut width.
Coordinate the grid with services and furniture
Overlay the floor boxes, cable entries and workstation positions. Check whether openings fall near panel edges or support nodes. A small plan adjustment may improve access, but it needs approval from the relevant designer rather than an unrecorded site decision.
Use the OA outlet planning guide to organize service information. For the offered floor, confirm the approved opening method and support requirements before releasing fabrication or site-cutting instructions.
Issue a drawing that can guide installation
| Drawing item | Purpose |
|---|---|
| Grid origin and orientation | Reproduce the approved layout |
| Full and cut panel zones | Show perimeter quantities and treatments |
| Columns and fixed bases | Identify local support conditions |
| Openings and outlet references | Link panels to the services schedule |
| Door transitions | Coordinate edges and finished levels |
| Detail references | Direct installers to approved arrangements |
Use clear panel or zone identifiers where there are multiple special details. A generic note stating cut to suit gives little guidance for supporting or documenting a complex junction.
Reconcile the drawing with the order quantities
Count stock panels, special panels and understructure from the approved arrangement. Keep the net room area, theoretical grid positions and ordered quantities separate. Offcuts should only be counted as reusable where their dimensions and treatment suit an approved detail.
The raised floor BOQ guide provides a useful structure for this reconciliation. Record cutting allowances and spares explicitly so later changes can be assessed against the same basis.
Control revisions through installation
If a wall or outlet moves, assess the affected panels and supports before issuing a revised drawing. Mark the superseded version and update the quantities where needed. Retain the final installed arrangement for future access and replacement work.
To request SunTree layout and quotation support, send the surveyed plan, proposed module, finished height and coordinated outlet locations. Identify unresolved dimensions so they remain visible assumptions rather than becoming hidden ordering errors.
