Measurement Flashcards
Define the Internal Dominant Face? (IDF)
Inside finished surface comprising more than 50% of the floor to ceiling height for each IDF wall section.
(ie main wall surface)
Define IDF Wall Section
Each internal finish of a section of an External Wall, ignoring the existence of any columns, that is either recessed from or protrudes from its adjacent section.
Define Common Facilities
Shared facilities that do not change over time
eg
- lifts
- plant rooms
- toilets
Define Component Area
The extent at ground level of the area of a Building covered by one or more roofs, the perimeter of which (sometimes referred to as the drip line) is the outermost structural extension, exclusive of ornamental overhangs.
What is the aim of IMPS All Buildings, 2023?
- Establish a globally consistent methodology for measuring all types of buildings
- promote international collaboration.
- All building classes into one set of standards.
- Renders obsolete the previous publications for individual sectors such as offices and residential.
- To provide guidance on best practice in property measurement.
Has IPMS 2023 been adopted by RICS?
No but,
Once adopted, it is envisaged the current RICS Property Measurement (2018) will no longer be relevant.
What definition’s does IPMS All Buildings set out?
- IPMS 1 – external measurement
- IPMS 2 – internal measurement
- IPMS 3.1 – External exclusive use
- IPMS 3.2 – Internal exclusive use
- IPMS 4.1 – Selected areas including internal walls
- IPMS 4.2 – Selected areas excluding internal walls.
What is IMPS 2 Residential used for?
Residential is for measuring the interior area of a residential building.
Sum of each floor level of a residential building measured to the internal dominant face
What is IPMS 3B?
Area in exclusive occupation (related closely to GIA)
Included (stated separately):
attics,
basements,
balconies,
garages,
limited use areas.
Excluded (still might be stated separately):
patios,
staircase openings,
unenclosed parking areas,
voids vertical penetrations that form part of common facilities).
What is shop depth?
Measurement from notional display window to the rear of the retail area
Define Gross Frontage
External measurement in a straight line across the front of the building from outside of external walls
How do you measure land?
Check the boundaries accurately with an OS plan and / or Land Registry title document, prior to calculating the area using Promap.
- You could also use a trundle wheel onsite.
- Use mathematical trigonometry or a planimeter for calculation of a site area
What does IPMS suggest to ensure accuracy of measurements?
- Measurer to state degree of tolerance reported as a percentage
- Recommends all measurements are supported by computer-generated drawings and verified on site.
What is common scale used for room plan?
1:50
What is common scale used for building plan?
1:100
What is common scale used for street/location plan?
1:1250
what is a scale?
Ratio of the length in a drawing to the length of the real thing.
What is used for measuring land?
- Software ‘Promap’ (info is sourced from Land Reg, OS maps – it is updated every 6 weeks).
- Trundle wheel
What are other ways to measure residential buildings as per CMP 2015?
- Net Sales Area – GIA of new or existing residential dwelling. It includes basement and mezz, but excludes areas with headroom less than 1.5m, garages, terraces, open-sided balconies and conservatories. Often used in valuation and marketing of resi dwellings in new developments.
- Effective Floor Area – this is useable area measured to internal face of walls of rooms. It excludes bathrooms, toilets, corridors, area of headroom less than 1.5m. Often used for council tax banding.
What are RICS members expected to do?
Advise their client or employer on the benefits of using IPMS
However, IPMS is not always suitable, RICS members must document the reason for departure.
What is the most up to date guidance for property measurement?
Property Measurement 2nd edition 2018 (mandatory professional standard)
- applies to all properties
- includes IPMS for resi and office
COMP 2015 applies to all other asset classes
What is the best practice guidance for industrial and retail?
Guidance Note: RICS Code of Measuring Practice, 2015
- It provides precise definition to ensure a common and consistent approach to measurement
Who governs IPMS
IPMSC (council)
What is important to note when measuring industrial units?
Clear height eg how many shelves can fit in, can a fork lift fit in the building, can you get a mezzanine in?
Need an elevation plan - not on site plans
