25
What is IPMS finished surface?
Wall surface directly above horizontal wall floor junction, ignoring any part-height walls, cladding, fittings, skirting boards, cable-trunking, pipework, heating and cooling units
26
What is IPMS IDF?
The inside finished surface comprising more than 50% of the floor to ceiling height for each IDF wall section
27
What is IPMS IDF wall section?
Lateral portion of an external wall, where the inside finished surface area of each part of a window, wall or other external construction feature varies from the adjoining lateral position of external wall, ignoring the existence of any columns
28
What is IPMS limited use area?
Areas that have restricted use, not fully functional for primary purpose of space
29
RICS Q - What are the main differences between IPMS 3 Office and NIA?
- Perimeter measurements are taken to the 'Internal Dominant Face' - No exclusions for restricted height of less than 1.5 metres - All columns are included - Area occupied by the reveals of a window when measured and assessed as the internal dominant face are included - On floors with multiple occupiers, the area is taken to the midpoint of the partition wall between tenancies - Covered galleries and balconies for the exclusive use of one tenant are included and stated separately
30
What is the reduction from GEA to GIA?
2-3%
31
What is the reduction from GEA to NIA?
15%
32
What are internal eaves height?
The clear height between the floor and the lowest point on the underside of the roof, e.g. at the eaves
33
What is site depth?
The measurement from the front to rear boundaries
34
What is shop depth?
The measurement from the notional display window to the rear of the retail area, including the thickness of the display window
35
What is built depth?
The maximum external measurement from the front to rear walls
36
What is gross frontage?
The overall external measurement in a straight line across the front of the building from the outside of the external walls or the centre line or the party walls
37
What is net frontage?
The overall frontage of the shop line measured between the internal face of the external walls
38
What should you consider when evaluating the level of accuracy that could be expected from a measured survey and one that is both achievable and acceptable?
- Purpose - Client's requirements and expectations - Building or site conditions - Time / cost elements - Ramifications if level of accuracy is deemed insufficient
39
How would you measure land?
- Check boundaries on site with an OS plan / Land Registry title document prior to calculating the area of a site using Promap - Trundle wheel or software like 'Promap' - Mathematical trigonometry or a planimeter for the calculation of a site area - A plot ratio is the ratio between the size of the site and the building footprint (GEA), This is also known as site cover. - 1 acre is 0.4046 hectare
40
What is a building line?
41
What is a scale?
Ratio of the length in a drawing to the length of the real thing
42
What scale is a room plan?
1:50 / 1:20
43
What scale is a site plan?
1:200 / 1:100
44
What scale is a location plan?
1:12500 / 1:12500
45
What scale is a drawing?
1:100 / 1:50
46
What scale is a detailed drawing?
1:10 / 1:5 / 1:2
47
What measurement tools are there?
- Tape - Rod - Laser device - Software
48
How accurate are lasers?
Within 1.5mm up to 200m but bright sunlight can distort measurements All measurement tools should be checked for accuracy frequently against a known distance and the results recorded in a log Lasers should be calibrated annually by manufacturers
