Level 1 Commentary
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/Professional/ 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)
RICS Professional Statement Property Measurement 2nd Edition (2018)
Possible mistake in submission - IPMS is incorporated but not the All Building 2023.
But it incorporates aspects of the IPMS suite of guidance.
What does the RICS Property Measurement 2018 incorporate?
- 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
–> IDF
–> IPMS - Def & application
- IPMS offices
- IPMS Residential
- Appendix A - Tolerances
Background - RICS Professional Statement Property Measurement 2nd Edition (2018)
This global RICS-led initiative introduced mandatory IPMS and practices aiming to avoid current inconsistent def of measurement in different counties
Led by the IPMSC (coalition) which is a global group of professional and not for profit organisations
RICS Property Measurement (2nd Edition) incorporates IPMS for Residential and Office Buildings.
Came into effect in 2019 following its first edition in 2016
AIMS RICS Professional Statement Property Measurement 2018
- Aims to bring global consistency, uniformity, clarity and transparency
. - Aimed to establish consistence in property measurement to be adopted by government and industry
. - Members are encouraged to report on a dual basis until IPMS is embedded into market practice, having regard to the client’s instructions
. - The RICS intention is that it will become mandatory practice
. - At Present all members must advise their clients about the benefits of IPMS
SUBMISSION
Accuracy –> RICS Professional Statement Property Measurement 2018
M&F responsibility to adopt appropriate measuring and computing 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 =Purpose of the measurement exercise?
. - CLIENT REQUIREMENTS =What are the client’s requirements and expectations in terms of accuracy and confidence in measurement?
. - SITE CONDITIONS = What are the building or site conditions at the time of survey that would influence how measurements are undertaken?
. - TIME/COST =What are the time/cost elements involved in the measurement and reporting?
. - RAMIFICATIONS- 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 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
What code relates to measuring practice
( –> RICS Code of Measuring Practice (2015) 6th edition)
RICS Code of Measuring Practice (2015) 6th edition
- GEA - (IPMS 1, equates closely)
- GIA - (IPMS 2 - equates closely)
- NIA - (IPMS 3 equautes somewhat)
Plus useful def, diagrams and application
Plus Technical definitions and diagrams
The code is intended for the UK only.
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
Tell me about what is included in NIA/GIA/GEA?
- NIA includes all spaces that can be used for occupation or activities, such as offices, corridors, storage rooms.
. - GIA represents the total floor area within a building, including all internal spaces, walls, and partitions. It includes the NIA as well as the internal walls, columns, and other structural elements.
. - GEA measures the total floor area of a building, including all internal spaces, as well as any external walls, projections, or elements that form part of the building’s structure.
Purpose of the Code
The purpose of the code is to provide succinct, precise definitions to permit the accurate measurement of buildings and land.
The code contains a hierarchy of definitions with the core definitions being:
- GEA Gross External Area
- GIA - Gross Internal Area - Approx 2-3% deduction from GEA
- NIA (Net Internal Area)
Asset and it’s measurement (depends on the purpose of the measurement task)
Industrial buildings GIA or NIA (and sometimes GEA depending on the purpose of measuring)
Offices - NIA
Retail - NIA
Reporting
-> As per the Application of this RICS Professional Statement Property Measurement 2018
M&F involved with measurement must comply with these requirements and retain the following information on file or in their report:
–PURPOSE purpose of the measurement instruction
– DATE OF INSTRUCTION date of the measurement instruction
– DATE date of measurement
– MEASUREMENT measurement standard adopted
– IPMS? if IPMS is not used, document the reason for departure
– TOOL measurement methodology adopted (e.g. laser measurer or tape measure)
– SCALE - scale of any plans used
– floor area schedule with relevant areas cross referenced to floor plans
– UNIT & CONVERSION unit of measurement and conversion factor, if applicable (e.g. square feet to square metres) and
– name of the RICS member and/or RICS regulated firm responsible for the instruction
Use of IPMS
(As per the RICS Property Measurement 2018)
RICS members are expected to advise their client or employer on the benefits of using IPMS.
However, it is understood that IPMS is not suitable in all circumstances and in these circumstances RICS members must document the reason for departure.
–> i.e. needing like for like for comparable so may need to measure on NIA over IPMS as not widely adopted and understood in the industry
–> Adopting IPMS terms when calculating or reporting the area of office and residential floor space on an IPMS basis is mandatory.
What is the definition of GEA?
AREA OF A BUILDING
MEASURED EXTERNALLY
AT EACH FLOOR LEVEL
Gross External Area 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
(The entirety of the space contained within the main external envelope of the building.)
