Build, live & derig

An event site is three sites. The build (crew, plant and structures going up), the live days (the public, every welfare and trade unit, the barriers) and the derig (crew again, structures coming down). Everything you place says which of the three it is on site for, and you can view the site in any one of them.

Presence: on site during

Every object, zone and barrier run carries a set of phases — any combination of Build, Live and Derig, at least one. The defaults follow what the thing is:

Change it on an object under ⚙ Parameters ("On site during"), and on a selected zone or barrier run with the On site during toggles (B · L · D) in the edit bar. Trackway and roads are not phased: trackway is laid for the build and stays through the derig. If you try to untick the last phase the control refuses — "An object must be on site in at least one phase — tick Build, Live or Derig."

The view phase

Show the site during — All · Build · Live · Derig — at the top of the sidebar, under the intro and above 1 · Site Boundary, so it is always in view; the same control is in the 🎪 menu. What is not on site in the viewed phase is not drawn, cannot be picked and is not counted in the tiles; All shows everything. A zone or run you draw while viewing one phase is on site in that phase. The view phase is yours: it is remembered in your browser, never saved in the design, so a collaborator or a reviewer sees their own.

The schedules and the planning report print each row's presence as its letters — B · L · D.

Pinning a sheet to a phase

A sketch sheet can be pinned to one phase for printing. In Sketch style the Site shown during select offers the viewer's phase, the build, the live days or the derig. A pinned sheet draws that phase whatever the viewer has chosen, the sidebar says "📌 This sheet is pinned to the … phase — change it in Sketch style", and its title block can print the phase with the {phase} token.

What the phases change

• The checks. Provision, exits and extinguishers are judged on the live days. The emergency route is judged per phase that a crossing fence and the zone are both on site — a live-only Heras line does not block the build-phase route. Crew toilets and basins during the build and derig counts every toilet and basin on site in that phase, public units included — set a public block to live only if the crew may not use it.
• The hire period. An item's days on site are the sum of the phases it is on: build days + live days + derig days from the demand dialog. See Hire schedule & budget.
• The outputs. The Event Safety Plan appendix captures the site plan in each phase.
