Q

What are the measurement practices?

A
  • Measurement + Calculations should be used in unit which is commonly adopted in jurisdiction
  • All measurement, bar height are taken horizontally
  • IPMS should be supported with computer generated drawings
  • Measurements should be independently verified
  • Building to be measured on a level by level basis

McGinty asks me if sq.ft / m2, I tell him to ensure he measure horizontally. He asks me to go to the computer room to scetch out. I doubt the measurements and go back to measure out of hours. All is correct and we apply to Mr.Hurlihy’s office.

Step 1 - Determine the IPMS Boundary

Step 2 - Other Considerations

Step 3 - Measure and calculate the areas included in IPMS X

Step 4 - Areas Included in IPMS 1 but Reported Separately

33
Q

External Floor Area - Identify external floor areas measured to the outside edge of floor construction

Sheltered Area - Identify sheltered area and boundary line along the edge of the permanent structural extension above

External Wall - Identify the remaining external wall

34
Q

IPMS 1 (Step 2) - Other Considerations

35
Q

IPMS 1 (Step 3) - Measure and Calculate

A

Notional Boundary - Identify any agreed notional boundary which differs from the IDF or external floor area

External Floor Area - Identify external floor areas and establish boundary lines along the floor - balustrade junction

Internal Dominant Face - Identify the IDF of all external walls

39
Q

IPMS 2 (Step 2) - Other Considerations

External Wall - Identify remaining boundary lines along the maximum physical extent of the external boundary wall

Demising Wall - Identify boundary line along the CenterPoint between demising tenants or buildings / Identify boundary lines along the finished service for other demised walls e.g. occupier and facility

Secondary Areas - Identify boundary lines of secondary area i.e. storage areas

44
Q

IPMS 3.1 (Step 2) - Other Considerations

A
  • Tenant related non permanent changes are disregarded
  • Areas occupied by walls and columns within boundary are not deducted

  • Structures beyond the covered area which do not form part of building are excluded.
45
Q

IPMS 3.1 (Step 3) - Measure and calculate the areas included in IPMS 3.1

External Floor Area - Identify any external floor area and establish boundary. Measure to junction but not beyond outside edge of floor

Sheltered Area - Identify any sheltered areas and establish boundary line along the edge of the permanent extension line

IDF - Identify boundary lines along IDF of all external and demising walls

Demising Wall - Identify Boundary along centerline of demising walls between occupants and identify boundary line along the finished surfaces for other demising walls i.e. standard facilities

Secondary Areas - Identify boundary lines of secondary area

49
Q

IPMS 3.2 (Step 2) - Other Considerations

A
  • Tenant related non-permanent changes are disregarded
  • Measurement taken to IDF of shared external walls between adjoining buildings
  • The areas of walls and columns within the boundary are not deducted
  • Upper voids are disregarded, ground floor included
  • Ignore recessed doors and lift opening, continue on finished surface boundary line
  • Measurement of mezz and upper levels floors treated as same as external floor areas
  • Standard facilities excluded
  • External floor areas measured to inter-most line of balustrade. then up to the IPMS 1 boundary of the external wall
  • Thickness between External floor areas and IDF is excluded
  • Sheltered areas measured to IPMS 1 external floor area boundary
  • Structures beyond covered area are excluded
50
Q

IPMS 3.2 (Step 4) - Areas included but reported separately

  • Sheltered Areas
  • External Floor Areas
  • Enclosed walkways or passages connecting separate Buildings, which form part of occupier’s exclusive area
