Alternate Measuring Methods

Public Works and Government Services Canada (PWGSC)

The measurment instructions (sometimes referred to as Schedule "B" of the Generic Lease Documentation Package) for property leased to the Canadian Government are as follows:

General

  1. If an outer building wall consists of at least 50% glass (based on a minimum ceiling height of 2,600 mm) the measurement shall be taken from the inside surface of the glass.
  2. If the glass surfaces are sloping or of any other irregular design the measurement shall be taken from the glass surface nearest the inside finish of the outer building wall.

Definitions

  1. Accessory Areas are the common use areas of the Building, along with their enclosing walls (except where such walls abut Building Service Areas), including toilets, janitor closets, slopsinks, electrical closets, telecommunication closets, public corridors and elevator lobbies.
  2. Building Service Areas are those areas, with their enclosing walls, necessary to the operation of the Building, including main entrance lobby, main floor elevator lobby, public stairs, fire towers, elevator shafts, flues, stacks, pipe shafts, other vertical ducts, air conditioning room (including fan rooms on floors), meter room, garbage room, janitorial storage room (serving the whole Building), dumbwaiter, and loading docks (serving the whole Building).
  3. The rentable area of a whole floor shall be the area within the outside walls computed by measuring to the inside finish (or surface of the glass, as appropriate) of permanent outer building walls without deduction for columns or projections necessary to the Building or for enclosures around the periphery of the Building used for the purposes of cooling, heating and ventilating, excluding from such measurement Building Service Areas, but including Accessory Areas within and serving only that floor and, if applicable, a proportionate share of Accessory Areas serving more than one floor.
  4. The rentable area of a portion of a floor shall be the area within the outside walls computed by measuring to the inside finish (or surface of the glass, as appropriate) of permanent outer building walls, to the inside surface of the corridor walls and to the centre of the partitions that separate the portion of the floor from adjoining portions of the floor, without deduction for columns or projections necessary to the Building or for enclosures around the periphery of the Building used for the purposes of cooling, heating and ventilating, excluding from such measurement Building Service Areas, but including a proportionate share of Accessory Areas servicing only that floor and, if applicable, a proportionate share of Accessory Areas serving more than one floor.
  5. The usable area of a floor or of a portion of a floor shall be the area within the outside walls computed by measuring in the manner described for computing the rentable area, excluding from such measurement Building Service Areas and Accessory Areas (together with the enclosing walls of such Accessory Areas which separate them from usable area on the balance of the floor) and also excluding the area occupied by columns and projections necessary to the Building or by enclosures around the periphery of the Building used for the purposes of cooling, heating and ventilating.
