Building data · Space Ledger

Target and grossing

Set the gross building target and the net-to-gross allowance, and read whether the program is over or under.

The spaces in the ledger are net areas. A building target is gross: it includes walls, structure, circulation and mechanical space. Space Ledger bridges the two with a grossing allowance.

Set the target #

Type the gross building area in Target in the toolbar, in square feet. Leave it at 0 if you don't have one yet.

Set the grossing #

Type the net-to-gross allowance in Grossing, as a percent. It's added on top of the net program. For example, 30% grossing on 10,000 SF net gives 13,000 SF gross.

Read the summary bar #

  • Net allocated: every space's subtotal added up.
  • + grossing →: the projected gross area, once the grossing is added. It shows when the grossing is above 0.
  • Target: the gross target you typed.
  • Remaining: how much of the target is left. When the program is too big, this reads Over by instead, in red.
  • The bar fills toward the target. Hover over it for the percent of target.

Compare the target with the projected gross, not with the net, unless the grossing is 0.

Net budget #

The net budget is the target with the grossing taken out: the net area you can fit. The % of net budget column and each department's share compare net with net, so the department shares add up to the program's percent of target.

Advanced grossing #

Departments can carry their own grossing, like a lab department with more support space than offices.

  1. Click Advanced grossing in the toolbar.
  2. In each department's header, type its dept grossing percent.

Each department's net is grossed by its own percent first, giving its departmental gross (DGSF). The building grossing then applies on top, giving the building gross (BGSF). The summary bar shows both.

The button stays on while any department has its own percent. To turn it off, set every department back to 0.

Match the project's building area #

A project can carry its own building area, set on the project page. When the program is in a project and the two numbers don't match, the tool says so once. To sync them, open Project ▾:

  • Use the project's building area sets this program's target to the project's number.
  • Set the project's building area sets the project's number to this program's target, so other tools can read it. It shows for the project's owners and admins.
