Greybox foundation pad (Modular Greybox Architecture Kit)
A 1.6 m square foundation pad with a chamfered upstand and a 0.6 m pedestal carrying four cast-in holding-down bolts, sized for the I-beam column.
Greybox I-beam span 2 m (Modular Greybox Architecture Kit)
Half-bay 2 m I-beam span with the same 360 mm section and end plates, for trimming a frame onto the 2 m sub-grid.
Greybox I-beam span 4 m (Modular Greybox Architecture Kit)
A 4 m 360 mm deep I-beam span with bolted end plates, four bolts per end and two web stiffeners. Carries a floor bay between columns.
Greybox I-beam column 3 m (Modular Greybox Architecture Kit)
A 3 m universal column: 0.3 m by 0.28 m I section between a bolted base plate and a cap plate, with four holding-down bolts and a stiffener each side.
Greybox slope reference wedge (Modular Greybox Architecture Kit)
Four 1 m slope facets at 10, 20, 30 and 45 degrees side by side on one base, with orange nose strips, for choosing a walkable gradient before committing to terrain.
Greybox 5 m measurement rod (Modular Greybox Architecture Kit)
A 5 m vertical measuring rod banded every 0.5 m in orange and pale grey on a weighted foot, for checking heights and clearances in a blockout.
Greybox objective marker post, neutral (Modular Greybox Architecture Kit)
The objective marker post with a pale neutral diamond instead of orange, for marking a second team, a disabled objective or a secondary route.
Greybox objective marker post (Modular Greybox Architecture Kit)
A 2.8 m objective marker: a steel post on a base plate carrying an orange octahedral diamond, with chequer height bands at 0.7 m and 1.4 m.
Greybox spawn marker pad (Modular Greybox Architecture Kit)
A 1.6 m round spawn pad: low disc, raised orange ring and a facing chevron, so a start point reads from above and from eye level.

A 4 m by 4 m thin reference tile with a chequer grid field in a dark border, for laying the 4 m module out on the ground before any geometry exists.
Greybox 1 m reference cube (Modular Greybox Architecture Kit)
An exact 1 m reference cube: chequer-gridded faces inside a dark 0.04 m edge frame, so a blockout can be measured by eye from any angle.
