34
Q

What are the NRM?

A

The RICS New Rules of Measurement: Order of cost estimating and elemental cost planning which provide a structured basis for measuring building works and a consistent approach for dealing with other components of an order of cost estimate or elemental cost plan.

35
Q

What would you expect the percentage of NIA to GIA/GEA to be?

A

It depends on the type of project being undertaken whether a school, hospital or office etc. If it were an office building I would expect NIA to GIA to be in the region of 70-85% where 70% is not good and 85% is excellent.

36
Q

When undertaking the measurements of a building, what factors are
you governed by?

A

RICS Code of Measuring Practice.
* The purpose of the code is to provide succinct, precise definitions to permit the accurate measurement
of buildings and land.
* The correct calculation of the sizes, areas and volumes associated of buildings are provided on a
common and consistent basis.
* This is to support surveyors undertaking property inspections for valuation, management,
conveyancing, planning, taxation, sale, letting and acquisition to provide a common framework to
measure buildings.
* The code contains a hierarchy of definitions with the core definitions being:-
o GEA.
o GIA.
o NIA (Net Internal Area)

37
Q

What are measured surveys?

A

Measured surveys involve taking measurements of sites or buildings in order to produce accurate drawings to scale and may include levels (Construction Industry Council Definition).
* They are usually specified to an agreed level of detail, to acceptable accuracy tolerances, scale, delivery, times and costs.
* Traditionally they were produced in 2D hard-copy line drawings, topographical plans, floor plans, sections and elevations.
* More recently digital data can come from the end product either in 2D drawing format or in 3D model format.

38
Q

What is Building Information Modelling?

A

Building Information Modelling (BIM) is the holistic process of creating and managing information for a built asset.
* Based on an intelligent model and enabled by a cloud platform, BIM integrates structured, multidisciplinary data to produce a digital representation of an asset across its lifecycle, from planning and design to construction and operations.

39
Q

When reporting defects within properties that require further investigation, what are the different category ratings within the Single
Survey?

A

1: No immediate action or repair is needed. Normal maintenance must not be treated as a repair for the purpose of the Single Survey.
* 2: Repairs or replacements requiring future attention. This rating is used when repairs are required when the defect is not considered to be serious or urgent
* 3: Urgent Repairs or replacement are needed now. This rating is to be used where if a defect is not addressed, it can cause problems to other parts of the property or may be a safety hazard. This rating must be used where the defect is of a serious nature or where immediate repairs are required. A serious
defect is one, which is likely to: compromise the structural integrity of the property; and/or
compromise the intended function of the building element; and/or seriously affect the health and/orsafety of the occupiers.

40
Q

What information would you typically look to obtain from a seller /occupier?

A
  • How long the seller has lived in the property.
  • Structural alterations undertaken with approximate dates, planning permissions and building regulations approvals.
  • Known defects and problems.
  • The age of service installations and maintenance records for central heating boilers.
  • Drainage where if private a confirmation of the usual emptying arrangements.
  • Ownership & maintenance of shared boundaries and access areas.
41
Q

What tools would you look to utilise when carrying out a survey?

A
  • Measuring devices
  • Moisture meter
  • Torch
  • Spirit level
  • Pocket mirror
  • Plumb bob
  • Compass
  • PPE -Mask, High vis, hardhat, Gloves ect.
  • First aid kit
    *Phone/ alarm
42
Q

What risk factors should you consider when inspecting a property?

A

Whether I am able to use inspection tools in a sensible and safe manner.
* To not climb on any furniture, garden walls, stand on boxes which could be unsafe.
* Only use fitted loft ladders if satisfied that they are safe.
* To not touch any part of the electrical installations, if unsafe electrics are detected.
* Do not adjust or move glass fibre insulation.
* Terminate the inspection immediately if:-
o Loose fill asbestos insulation is identified.
o If I injure myself in any way.
o If the seller/occupier attempts to intimidate or abuse me in any way.
* Check in with the office at regular intervals and do not end the day with an unaccompanied inspection,
unless another responsible person is informed of their whereabouts.
* Keep car keys, mobile phone and/or valuables safe during the inspection.
* Do not allow the occupier to lock doors behind me.

43
Q

What desktop information would you typically look to obtain prior to undertaking the inspection?

A
  • Estate Agent particulars.
  • Relevant site information (e.g. the nature of the subsoil).
  • Particular exposure to wind-driven rain or frost attack.
  • Details of previous works and permissions.
  • Guarantees, warranties and any supporting reports, specifications and quotations.
  • Conservation area or listed building status.
  • Lease details.
44
Q

  • Details of the Surveyor including RICS membership status, experience and qualifications.
  • Procedures prior to the inspection.
  • Terms of payment.
  • Cancelling the appointment.
  • Liability.
  • Complaints handling procedures.
45
Q

What are the measured surveys?

A
  • Measured surveys involve taking measurement of sites or buildings in order to produce accurate drawings to scale and may also include levels as well as the buildings dimensions.
  • Measured surveys are usually specified to an agreed level of detail and to acceptable accuracy tolerances, scale, delivery, times and costs.
46
Q

Who carries out measured surveys?

A
  • Typically they are carried out by land surveyors affiliated to the RICS and the Chartered Institution of Civil Engineering Surveyors.
  • Measured survey companies can also be found within the Trade Survey Association (TSA).
47
Q

What is meant by the term GNSS?

A

GNSS (Global navigation satellite systems) can be used to give x and y plan accuracy with great accuracy in support of carrying out measured surveys.
