The main part of the NRMM is the tabulated rules of measurement for
building works which are written with the following objectives:
To provide a standard set of measurement rules for the preparation of bill ofquantities (BQ) and schedules of works for building works, and a framework thatcan be used to develop bespoke and standard schedules of rates;
To provide Preambles which spell out ‘works and materials’ deemed to beincluded in the building components/items in the BQ (BQ Items);
To provide a guidance in the drafting of the Specification and ‘Preliminaries’;
To reduce the number of measurable BQ Items and simplification ofmeasurement of the same , both of which are aimed to make NRMM more BIM-friendly;
To provide specific rules of measurement which cannot be inferred from thebuilding components/items description and ‘Preambles’
To give a guidance as to the specific information to be shown in the 2Ddrawings or to be input into 3D models (to facilitate the extraction of quantities)by the respective design consultants; and
To provide guidelines to create standard building components / itemsdescriptions by ‘levels’ and with ‘unit of measurement’ comprised in each ofthe Work Sections.

• NRMM has added rules of measurement for some building components/items for which SMM2 has left out i.e. IBS, ‘Alteration, repairs and conservation’, ‘Ground remediation and soil stabilisation’, ‘Crib walls, gabions and reinforced earth’, ‘Site work’ and ‘Transportation’
Preliminaries – Work Section 1:
Information and requirements are specified under the following headings:-
Generally
Bills and Pricing / Pricing
Materials and Samples
Form of Contract
Contract Administration
Temporary Works
Monitoring Works
On Completion
List of the preliminaries items to be
considered under each main heading
Information that shall
be included within
each of preliminaries
items
Groups of the building components/items
List of some important heads of information
to be incorporated in the specification
OBJECTIVE
The drafting of the specification for the work
section shall be based on the heads of
information given and other additional heads
if any
Gives a general guideline as to the specific
information to be shown in the 2D drawings,
or, to be input into the 3D model for each
group of the building components/items
OBJECTIVE
To facilitate the extraction of ‘quantities’ for
the building components/items within each
group and to be used as a guide in the
preparation of the relevant parts of the
‘Model Content Matrix’ in the BIM Execution
Plan
OBJECTIVE
It gives specific rules of measurement where
neither the ‘Preambles’ nor the building
components/items description can infer such
rules
Specific rules of measurement in addition to
those inferred from the building
components/items description and
‘Preambles’
OBJECTIVE
- In the preparation of the BQ, one can just
state that the BQ shall be read in
conjunction with the ‘Preambles’ in NRMM
instead of repeating them in the
Specifications.
- To serve as a standard, however is not
exhaustive and additional ‘Preambles’ if
needed, can be added in the
Specifications accordingly
It gives the ‘Preambles’ related to each work
sections as a whole or each group under
each work section
Lists the building components/items
commonly encountered in building works
under each group, and represents the
heading of the description (the ‘Heading’)
for the building
components/items
Lists the unit of measurement for building
components/items
Lists the information, including any dimension
requirements, that shall be included in the
description of the building
components/items;
Lists the supporting information, including any
additional dimension requirements, which
shall be included in the description of the
building components/items
Lists the further supporting
information, including any
additional dimension
requirements, which shall be
included in the description of the
building components/items
- Definitions of some generic
terms and phrases used in
connection with the building
components/items;
- Additional information to be
added into the Heading or as
‘Notes’ preceding the
Heading, or the specific level
to complete the description of
some of the building
components/items; and
- Clarification of the approach
to quantification and
description of building
components/items
Objective
The user can easily form a building component/item description by
extraction the relevant ‘Heading’, ‘Level 1’, ‘Level 2’ and ‘Level 3’ as the
case may be, and adding additional information as advised in ‘Notes,
comments and glossary’ and in the bracket, (____), and the ‘unit of
measurement from the relevant table. This would standardize and simplify
the building components/items description and at the same time facilitate
the codification of the same
To lessen the number of building components/items so as to make NRMM BIM-
friendly, FOUR methods being adopted as follows:
• Use of a generic term to include many like items
Use of composite item
• In copings, kerbs, upstands, sills, lintels, fascias, fans, countertops and the like; including
formwork and/or reinforcement
• Flush door;(thickness and type) plywood on both sides and timber lipping all round ; complete with (dimensional description and type of timber) door frame and fixing in position; prepare and apply (painting system) to all exposed timber surfaces after fixing ; hanging; as shown in drawing (drawing nr)
Use of composite item
Use of ‘total depth’ and ‘total height’ instead of stages
Measurement in m3 without stating the thickness or in m2 instead of m with
height stated
CONCLUSION
The objectives of NRMM encompass NOT only the standardization of the
components/items descriptions, Specification, Preambles and Preliminaries
in production of BQ documents but also the facilitation of the
implementation of 5D BIM.
The present NRMM is in its raw form and it is our fervent hope that once the
draft is circulated to the relevant stakeholders in the building industry, we
would have some constructive comments and feedback before it is finally
published.
