Measurement / Mapping Flashcards
What must be included on all plans?
A north point
Red line outline
Scale
What is difference between a plan and a map ?
A plan uses a smaller scale and a plan is a true scale representation. Whereas a map is drawn at a scale that features cannot be seen.
What are the scales for a site plan, location plan
Site plan – 1:100, 1:200 and 1:500
Location plan 1:1250 and 1:2500
What is the typical scale for a room and building:
Room: 1:50
Building Plan: 1:100
What is the typical accuracy of an OS MAP
Generally within one meter of accuracy
What does a plan need to have to be land registry compliant ?
- Has been drawn accurately to a stated scale
- 1:1250 – 1:500 for urban properties
- 1:2500 for rural properties (fields and farms etc)
- Shows its orientation (for example, a north point)
- Not marked as “for identification only” or similar wording
- Clarifies its general location by showing roads, road junctions or other landmarks
- shows sufficient detail to be identified on the Ordnance Survey map
- Includes a bar scale
- the whole of the property including any garage, parking space, bin store or garden ground.
- buildings in their correct (or intended) position.
- access drives or pathways if they form part of property boundaries.
- undefined boundaries accurately and where necessary, by reference to measurements.
- measurements in metres to 2 decimal places.
- land and property clearly (for example by edging, colouring, stippling or hatching) - the edging/colouring must not obscure any other detail.
- all colours referred to in the deed, with their extents clearly defined.
how does a topographical survey help you to assess the opportunity on a plot?
A topographic survey gathers data about the natural and man-made features of the land, as well as its terrain. Permanent features such as buildings, fences, trees and streams accurately define the ground and its boundaries. Land contours and spot levels show the elevation of the terrain. Topographic maps are used by architects, engineers, building contractors and others to accurately visualise their sites and help bring forward development.
What is GIS
Geographic Information System
What professional and guidance relates to property measurement
RICS property Measurement 2nd Edition, January 2018. Effective 1st May 2018
Code of measuring practice 6th Edition, May 2015- effective 1st May 2015
What are the different method of measurements?
Office- IPMS 1, IPMS 2, IPMS 3
Residential: IPMS 1, IPMS 2, IPMS3, IPMS3A, IPMS3B, IPMS3C
What is GEA?
Gross External Area is the area of a building measured externally at each floor
Used for planning applications, site coverage and calculating build costs on residential property for insurance purposes
What is GIA ?
Gross Internal Area is the area of a building measured to the internal face of the perimeter walls at each floor.
Can be used for build cost estimation, estate agency and valuation.
What is NIA?
Net Internal Area is the usable area within a building measured to the internal face of the perimeter walls at each floor level
What is IPMS
International Property measurement Standards
How did you measure a site/piece of land?
Using a trundle wheel in Meters, Hectares and Acre
What is the structure of the IPMS?
Structure of IPMS All Buildings and relationship to other standards
IPMS 1 and IPMS 2 are external and internal measurements respectively for a whole or part of a building. (1 External ) (Internal)
IPMS 3.1 and IPMS 3.2 are external and internal measurements respectively required for exclusive occupation.
IPMS 4.1 and IPMS 4.2 are internal measurements required for selected areas, including internal walls and columns and excluding walls and columns respectively.
The use of component areas is optional; however, they enable analysis of a building and can also be used to convert between IPMS and other standards.
What do you know about the RICS Property Measurement 2nd Edition 2018?
International Property Measurement Standards are a mandatory framework and definitions for the measurement of property.
What do you know about the RICS Code of Measuring Practice?
A
The RICS Code of Measuring Practice, 2015 is still the best practice document for all measurement exercises except for offices and residential properties.
It provides precise definitions to ensure a common & consistent approach to measurement.
What is Gross External Area (GEA)?
The area of a building measured externally at each floor level.
What is Gross Internal Area (GIA)?
The area of a building measured to the internal face of the perimeter walls at each floor level.
What is Net Internal Area (NIA)?
The useable area within a building measured to the internal face of the perimeter walls at each floor level.
What are the differences between GIA and NIA?
NIA:
- excludes columns
- excludes shared internal walls
- excludes common areas such as entrance halls, toilets, stairwells, lift.
GIA:
- includes columns
- includes all internal walls
- includes common areas.
What is the conversion from acres to hectares?
1 acre = 0.4046 hectares.
1 hectare = 2.471 acres
What is an Ordnance Survey Map?
Ordnance Survey (OS) is the national mapping agency for Great Britain. An OS Map uses OS mapping data.
What is GEA used for?
It is used for:
- Town Planning
- council tax valuations
- building cost estimates for houses
What is GIA used for?
It is used for
- Estate Agency
- rating
- building cost estimation and valuation of industrial/warehouses
- valuation and rating of retail warehouses and food stores.
What is NIA used for?
Similar to GIA but for shops and offices.
How would you measure an office using NIA?
Include:
- kitchens
- ramps/sloping areas within the useable area
- areas occupied by skirting and perimeter trunking
Exclude:
- WCs
- Plant and lift rooms
- Areas less than 1.5m in height
- Permanent circulation areas
