70 Queensway: Why did you use 2D Drawings?
The client only wanted 2D drawings which allowed us to fee appropriately.
If the client wanted 3D I wouldn’t have been able to carry out the instruction as I don’t used Revit or have had any training.
70 Queensway: What measurement standard was used?
IMPS 2 (Gross Intenral Area) was used during the inspection and production of information.
Internal dominant face.
The internal dominant face (IDF) is the inside finished
surface comprising more than 50% of the area between the floor to ceiling height for each IDF wall section. If such does not occur, then the finished surface is deemed to be the IDF.
If IPMS 3 used: Component areas listed as colours (light blue = workspace).
70 Queensway: What level of detail was required?
During discussions with the Landlord and their use of the drawings I established a high degree of detail was required which allowed me to fee appropriately.
For example I was recently instructed to provide a Lease plan which needed a degree of detail though no nearly as much as my instruction at 70 Queensway.
70 Queensway: Why was a high degree of detail required?
A high degree of detail was required as the drawings were being used for a full refurbishment of the building therefore requiring a precise degree of information.
From knowledge the structural frame was being altered, although the SE would measure the frame they used my information as a base point.
70 Queensway: How did you measure the elevation?
I utilised a second person during the external measured portion which allowed me to fully record the building’s measured information.
What is IPMS and tell me briefly what each section means?
Standardised measurement internationally.
IMPS 1 - GEA (All area of building measured externally) includes external balconies and terraces.
IMPS 2 - GIA (All area of building measured internally) includes external balconies and terraces.
IPMS 3 - NIA (Usable area and measured on an occupier by occupier basis). Excludes standard facilities and common areas etc. Includes non-structural partitions if wholly occupied. Half width of common/shared walls.
IDF: Areas occupied by windows are measured to the glass if the area of the window covers more than 50% of the wall.
Component Areas for IMPS 2 and 3 (light blue for work space etc.)
Included in report but stated separately:
Balconies
Roof terraces
Limited use areas.
What does IMPS 3B Include/exclude?
IMPS 3B - Net Internal Area
Includes: Terraces, balconies and limited use areas.
excludes:
Internal structural walls.
Piers, columns, chimney breasts, ducts and other projections.
Stairwells and landings.
Corridors and other circulation areas used in common with other occupiers or of a permanent essential nature.
What does IMPS 2 include/exclude?
The area of a building measured to the internal face of the perimeter walls at each floor level.
Includes:
Areas occupied by internal walls and partitions.
Columns, piers chimney breasts, stairwells, lift-wells, other internal projections, vertical ducts, and the like.
What does IMPS 1 include/exclude?
Refers to the whole area of a building taking each floor into account, including perimeter walls.
This includes:
Perimeter wall thickness and external projections.
Areas occupied by internal walls (whether structural or not) and partitions.
Columns, piers, chimney breasts, stairwells, lift wells, and so on.
When should IPMS 1, IMPS 2 and IMPS 3B be applied?
IMPS 1 (GEA) It’s used when assessing areas for planning application purposes.
IMPS 2 (GIA) It’s used when assessing building costs, and when calculating areas for Building Regulation purposes and valuations.
IMPS 3B (NIA) It’s a measure of the usable area and is used in valuation assessments, though GIA is often used.
