Methodology of Land Use Survey for I Zones


Methodology
@ @ @ @
(1) @ A survey on the individual units within the industrial buildings in the 26 areas zoned I was undertaken between 3.11.2008 and 2.4.2009 (the survey).
@ @ @ @
(2) @ Internal floor area (IFA) for each unit as in December 2007 obtained from the Rating and Valuation Department (R&VD) was used as the basis of the subject Assessments.  For analysis purpose, the figure was converted into gross floor area (GFA) by multiplying 1.3333.
@ @ @ @
(3) @ Predominant use (i.e. use occupies 50% or more in floor space) in each unit will be recorded during the on-site inspection.  If a single company is operating in several units within an industrial building, the major use of these units would be collectively recorded as the predominant use of these units.
@ @ @ @
(4) @

For each unit, information was collected through the following manner:

(a) direct face-to-face interview with the staff at the unit;
@ @ @ @ @
@ @ (b) @ if (a) above is unsuccessful after the visit, a letter will be left to the unit to request the responsible person to complete the questionnaire enclosed and return to PlanD.  Alternatively, the responsible person may choose to complete the questionnaire through a telephone interview by the PlanD staff;
@ @ @ @ @
@ @ (c) @ if (a) and (b) above are unsuccessful, any information on the concerned unit collected from the management office/neighbouring units will be used; and
@ @ @ @ @
@ @ (d) @ if all the above are unsuccessful, the unit is classified as a non-response case.
@ @ @ @ @
Broad Factors for Determining Building Conditions
@ @ @ @ @
In determining building conditions, the presence and degree of seriousness of the following factors are taken into account:
@ @ @ @ @
@ @ (a) @ structural defects (e.g. cracks in outer walls, bulging or sagging walls, rusted steel in beams or supports); and
@ @ @ @ @
@ @ (b) @ signs of wear and tear (e.g. rusted/defective exposed drain pipes and gutters, flaking/decaying external finishes including paint works on facades, rusted/insecured appendages on external walls, and rusted/defective window frames/panes).

Definitions of Vacancy Rate and Take-up
@ @ @ @ @
Vacancy rates (from 2003 to 2007): the percentage of industrial floor space not physically occupied at the time of the survey conducted at the end of the year.  The figures are sourced from R&VD.
@ @ @ @ @
@ @ i.e. @ Vacancy Rate = total floor area of vacant units total floor area of all units of buildings in I zone
@ @ @ @ @ @ @
Vacancy rate (for 2008): the percentage of industrial floor space not physically occupied as observed during the survey.
@ @ @ @ @ @ @
@ @ i.e. @ Vacancy Rate = total floor area of vacant units surveyed (by PlanD) total floor area of all units of buildings in I zone (from R&VD)
@ @ @ @ @ @ @
Take-ups (from 2003 to 2008): the net increase of industrial floor space as compared to previous year.
@ @ @ @ @ @ @
@ @ i.e. @ Take-up =

nenew industrial buildings completed in the year (from B.O.O. returns) + vacancy at the beginning of the year (by R&VD) V industrial buildings demolished in the year (from B.O.O. returns) V vacancy at the end of the year (from R&VD)
