Measurement Flashcards
What is the up-to-date guidance on measurement for RICS?
- RICS property measurement (2018) (2nd edition = overarching)
- IPMS AB (2023) is of mandatory application for office and residential
- With all other assets, COMP (2015) can still be adopted.
How do you decide which to use?
- RICS Property Measurement (2018) (2nd Edition) refers back to the measurement bases defined within IPMS AB and the Code of Measuring Practice.
- Requirements of the instruction would determine the method, and I would document this clearly in the written client report.
What is IPMS?
- It is a new, principles-based, international standard which specifies how to measure property assets
What are the perceived benefits of IPMS?
- Avoiding inconsistent definitions of measurement
- Bringing greater global transparency.
What are the key RICS documents for measurement?
IPMS Property Measurement (2018)
being updated
IPMS AB (2023)
COMP (2015)
What is IPMS1, how is it measured, and key difference to COMP?
- Measured to external extent of external wall
- Inclusion of external floor areas such as balconies and rooftop terraces.
What is IPM2, how is it measured and key difference to COMP?
- Measured to the internal extents of the IDF rather than to the internal face of the perimeter walls.
What is the IDF?
- Inside finished surface comprising more than 50% of the floor to ceiling height for each wall section. E.g windowsills.
What is IPM3.1 and IPMS3.2?
- Exclusive occupation (external walls)
- Exclusive occupation (IDF)
What is IPMS 4?
- IPMS for selected floor areas
- 4.1 = including floor area occupied by walls and columns
- 4.2 = excluding floor area occupied by walls and columns
How do plans very in detail?
- Sales plans more simplistic, aesthetics and flow of apartment
- Construction issue drawings much more detailed, HVAC info
What scale are plans drawn to?
- Floor/lease plans: 1:100
- Site/location plans: 1:1250/1:2500
What does BIM stand for?
Building Information Modelling
What is BIM?
Benefits/disadvantages of BIM?
Building Information Modelling
A digital process that integrates multi-disciplinary data on a project, can be used throughout full lifecycle of building.
- Reduce human error & save time
- Real-time updates when design changes
- However, high initial cost with software and training
How do you ensure accuracy when measuring?
- Ensure equipment is checked and calibrated. E.g kinks in tape or laser calibration
- Use repeated measurements to reduce random errors
What is accuracy?
How close a measured value is to the true or accepted value
Name some common measurement techniques and how you can ensure accuracy
- Inside: tape measure or a laser distance meter
o Tape Measure: ensure it’s a high-quality and free from any kinks or damage.
o Laser distance meter: ensure calibrated regularly give accurate readings - Outside: Total Station
o Theodolite for angles and electronic distance meter for distances
What is a Federated model?
- Combined BIM model created by integrating discipline-specific models (e.g architectural, structural, MEP) into a single, cohesive representation of a project
What would you expect to see included on a Land Registry compliant lease?
- Must be drawn accurately to scale (1:100 lease plan, 1:1250 location plan)
- Must show orientation (north point)
- Must show sufficient detail of surrounding features
- The plan must not be marked ‘Draft’ or ‘For identification only’ or ‘Do not scale from this drawing’
- Must clearly show extent of property, and on which level
