I am familiar with the RICS Property Measurement 2nd Edition, incorporating International Property Measurement Standards (IPMS) All Buildings (2023).
I am also aware of the RICS Codes of Measuring Practice and bases including GEA, GIA and NIA.
IPMS aims to provide an international benchmark, as well as confidence and consistency in property measurement worldwide.
I am aware of the parameters involved in evaluating accuracy levels, such as the site conditions and the purpose of the measuring exercise.
Main codes/Practice Statement & International Standards
RICS Professional Statement Property Measurement 2nd Edition (2018)
RICS Code of Measuring Practice (2015) 6th edition
International Property Measurement Standards: All Buildings (2023)
–> Published by the International Property Measurement Standards Coalition (IPMSC)
What does the RICS Property Measurement 2018 incorporate?
(Focus on IPMS for office & residential)
- Application of Prof Statement
--> Application (date of measurement, scale, use, purpose)
–> Accuracy (site conditions, purpose, client requirement = below)–> Use of IPMS (Benefits to clients = below) - Technical definitions–> Internal Dominant Face
--> IPMS - Def & application
- IPMS offices
- IPMS Residential
- Appendix A - Tolerances
What is IPMS
It is a new, principles-based, international standard which specifies how to measure property assets. It means that for the first time, property will be measured in a consistent way around the world.
IPMS does not define the units of measurement (e.g. feet and metres) but instead what is included in the measurement of property floor space.
to ensure consistent reporting
Purpose /aims
IPMS All Buildings 2023
- The RICS are yet to adopt this new mandatory form of measurement developed by the IPMSC
- Aims to establish a consistent methodology for measuring all types of buildings globally
- Aims to promote international collaboration
- Harmonises all building classes into a single document into one set of standards
- It will render obsolete the previous publications for office & residential measuring
- Aims to provide high level, overarching standards that provide guidance on best pratcice in property measurement
- Once adopted by the RICS, its envisioned that the current RICS Property Measurement 2018 will not be relevant
IPMS 1, 2, 3
IPMS 1 = –> Used for measuring the area of a building including EXTERNAL walls on a floor by floor basis
IPMS 2 –> Used for measuring the interior of an office to include all areas available for direct use measured to the internal dominant face (IDF) of the wall on a floor by floor basis in component areas
IPMS 3 –> - Uses the term ‘useable floor area’ meaning space for the exclusive use of an occupier. Measured to the internal dominant face on a floor by floor basis
RICS Code of Measuring Practice (2015) 6th edition
The RICS Code of Measuring Practice (2015) is still best practice document for all measurement exercises expect for office & residential
Provides precise definitions to ensure a common & consistent approach to measurement
GEA
RICS Code of Measuring Practice (2015) 6th edition Bases GIA and NIA.
Gross External Area
GEA is the area of a building measured externally at each floor level.
- Used for Town Planning, Rating and Council Tax and Building cost estimates for houses
Includes: * Loading bays * Columns * Left Wells * Lift room and plant rooms * garages * internal balconies
Excludes - * Canopies, * External Balconies, roof terraces * Fire Escapes, * Garden Store i.e. Green houses * Voids over/under structural, raked or stepped floors
GIA
RICS Code of Measuring Practice (2015) 6th edition
Gross Internal Area is the area of a building measured to the internal face of the perimeter walls at each floor level
Used - Property management – GIA is a basis of measurement for the calculation of service charges for apportionment of occupiers’ liabilities
- Used for Estate agency, rating, valuation of industrial / warehouses, Building cost estimate, department stores
GIA Includes:
- Toilets * Column * Lift wells * Loading bays * Chimney breast * Stairwells * Garage * Conservatories
- Lift rooms / plant rooms
GIA Excludes
- Canopies * Covered Ways * Fire Escapes * External Walls * External Balconies * Garden Store e.g. Greenhouse
NIA
RICS Code of Measuring Practice (2015) 6th edition
- Net Internal Area is the usable area within a building measured to the internal face of the perimeter walls at each floor
level
The usable space within a building measured to the face of the main external walls.
Used - Agency, Marketing and valuation of retail and office accommodation
NIA - approx 15% deduction from GIA
Includes
- Kitchens * Built in cupboards * Atria with clear height above, measured at base level only
- Entrance halls (unless multi let) * Ramps, sloping areas and steps within usable areas
- Areas occupied by ventilation/ heating grilles * Notional lift lobbies and notional fire corridors
NIA Exclusions:
- Toilets * Cleaners Rooms * Plant and lift rooms * Stairwells * Area less than 1.5 m in height
- Vehicle parking areas
Accuracy
–> As per RICS Professional Statement Property Measurement 2018
M&F responsibility to adopt appropriate measuring and COMPUTER PROCESSES so as to satisfy the requirements of clients and users.
M&F must consider the following parameters when evaluating the level of accuracy:
- Purpose of the measurement exercise?
- What are the client’s requirements and expectations in terms of accuracy and confidence in measurement?
- What are the building or site conditions at the time of survey that would influence how measurements are undertaken?
- What are the time/cost elements involved in the measurement and reporting?
- What would be the ramifications if the level of accuracy is deemed insufficient for the purpose?
Consideration of these issues ^ will enable the necessary EQUIPMENT and PROCEDURES to be adopted for the various stages of measurement and area calculation.
Accuracy of measurement
–> laser
Lasers tenant to be accurate to within 1.5 mm up to 200 m
But bright sun light can distort measurements
All measurements tool should be checked for accuracy frequently against a known distance and the results recorded in a log
Lasers should be calibrated annually by the manufacturers
Accuracy “Appendix A: Tolerances”
–> As per the RICS Professional Statement Property Measurement 2018
Appendix A shows ‘The survey accuracies shown are industry standard’. Showing the survey scale and the level of accuracy expected in mm
1:20 = +/- 5mm
1:50 = +/- 100mm
1: 100 = +/- 25 mm
1:200 = +/- 50 mm
Level 2 Commentary
Measuring a vacant RETAIL UNIT –> Fenchurch Street, London
Ahead of my inspection, I ensured my laser device had batteries and made sure it had recently been calibrated and tested. This ensured sufficient and accurate measuring could take place.
I measured this retail unit using an existing floor plan. I measured on a Net Internal Area (NIA) basis which included storerooms formed by non-structural partitions
