COMPARISON BETWEEN
BIM, CAD &
MANUAL MEASUREMENT
AT DIFFERENT STAGES

1. Preparation/ Briefing Stage
2. Design Stage
3. Pre-Construction Stage
4.Construction Stage
5. Post-Construction Stage

BIM
✔ BENEFITS
Better communication
Planners can visually communicate the planned construction
process to all project stakeholders.
Site logistics
Planners can manage laydown areas, access to and within the
site, location of large equipment, trailers, and so forth.
PREPARATION/ BRIEFING STAGE | DESIGN STAGE | PRE-CONSTRUCTION STAGE | CONSTRUCTION STAGE | POST-CONSTRUCTION STAGE

BIM
✗ CONSTRAINTS
High Training Costs and Learning Curve
Implementing new technologies such as BIM technologies is costly in
terms of training and changing work processes and workflows.
Everyone must be on board to make the BIM effort worthwhile
It is difficult to ensure that all project participants have the
willingness to participate in the use of the building information
model.

CAD
✔ BENEFITS
Increase productivity
Reduce effort levels.
Accuracy and Minimizing Errors
More reliable as compared to humans.

CAD
✗ CONSTRAINTS
High initial cost
Famous but excessive high cost.
Disrupt work if malfunctions happen
Computer breakdowns, not having a backup.

Manual Measurement
✔ BENEFITS
No specific training required
Does not require to undergo specific training programs unlike
BIM and CAD.
Cost saving
Saves cost compared to BIM and CAD measurement as the
software required substantial investment.

Manual Measurement
✗ CONSTRAINTS
Time consuming for decision making
More time consuming in keeping the dates and information of
the project up to date as compared to BIM and CAD
measurement which make decision making slower.

BIM
✔ BENEFITS
Accurate visualization of a design
BIM produces realistic three-dimensional views and
visualization walkthroughs for design clarity
Generation of Consistent 2D drawings at any design stage
Accurate and consistent drawings can be extracted from any
set of objects or specific view of the project

BIM
✗ CONSTRAINTS
Experts required
BIM is a new software in the market so there are limited
experts such as designers working in the field.
High software cost
BIM software requires a substantial investment in new
technology.

CAD
✔ BENEFITS
More work loads
Can handle and control more than humans.
Viewed from different angles
Showing every detail of the different viewpoints.

CAD
✗ CONSTRAINTS
Amendments must be made manually
Quantities of items and materials needed to be modified in
the BQ.
Cost of computer systems
New companies have problems affording it.

Manual Measurement
✔ BENEFITS
Client’s satisfaction
Changes can be made manually on the spot when there is
variation on the design to provide a clearer view and
understanding for the client immediately.

Manual Measurement
✗ CONSTRAINTS
Human error
Variations may occur and the scale usage may not be accurate
enough due to human error such as parallax error.
Time consuming
When variation occur, drawing manually consumes a lot of
time as there are several drawings needed to be produce in a
project

BIM
✔ BENEFITS
Increased building performance and quality
Developing a schematic model prior to generating a detailed building
model allows careful evaluation of the proposed scheme to
determine whether it meets the building’s functional and sustainable
requirements.
Cost estimation
Provide fast, effective and efficient quantity take-off and cost
estimation.

BIM
✗ CONSTRAINTS
Legal barriers
Contractual and legal changes are required on several fronts
to facilitate the use of BIM and more collaborative project
teams.

CAD
✔ BENEFITS
Accuracy of construction drawing and numbers
Humans have high possibility of making errors.
Ease of generations of drafting processes
Produce different type of elements at a faster pace

CAD
✗ CONSTRAINTS
Small error leads to bigger problems
Infos must be checked properly.
Risk of getting duplicated work
Due to idleness of the designer.

Manual Measurement
✔ BENEFITS
Lower risk of loss of information
Manual measurement will not face obstruction such as power
failure or clashes of software as is it based on paper works

Manual Measurement
✗ CONSTRAINTS
Lower accuracy of measurement
Taker off may be confused with the information received and has a
higher tendency of human error which result in lower accuracy of
measurement.

BIM
✔ BENEFITS
Discovery of design errors and omissions before construction
Due to virtual 3D building model is the source for all 2D and 3D
drawings, design errors caused by inconsistent 2D drawings are
eliminated.
Quick reaction to design changes
Design updated automatically when suggested design change is
entered into the building model.

BIM
✗ CONSTRAINTS
Incompatibility with partners
BIM is not yet universally used among construction
professionals.
Be extra cautious
Slight mistake made when inserting the design changes could
result in a different outcome.

CAD
✔ BENEFITS
Electronic drawings can be easily understood
Clearer view of the building, reduce time wondering.
Standardized layout
Makes filing and archiving more efficient to do.

CAD
✗ CONSTRAINTS
Measurements are restricted
Certain measurements cannot be achieved
2D area
3D volume

Manual Measurement
✔ BENEFITS
Cost effective
Most cost effective method as everything is done manually by
hand and the only cost involves is the printing of drawings and
the wages of the worker.
Reduce cost
It does not require additional investment in training and
education like BIM and CAD measurement.

Manual Measurement
✗ CONSTRAINTS
Visual and dimensional restriction
Does not provide 2D, 3D, 4D and 5D visualisation of cost
elements and design as compared to BIM and CAD software.
Rework
During the construction stage, variations may occur and
results in reworking on the quantity of the measurement
which consumes time.

BIM
✔ BENEFITS
Improved commissioning and handover of facility information
The general contractor and MEP contractors collect information
about installed materials and maintenance information for the
systems in the building during construction process.
Better management and operation of facilities
BIM provides a source of information such as graphics and
specification for all systems used in a building.

BIM
✗ CONSTRAINTS
Maintenance team
Often hired after the construction done.
Not all maintenance team has experience in using BIM
software.

CAD
✔ BENEFITS
Manage electronic documents
Can be more organize, fasten the process of construction.

CAD
✗ CONSTRAINTS
Professionals needed in order to operate CAD
Knowledge must be learnt before using

Manual Measurement
✔ BENEFITS
Easier accessibility
The operation and maintenance manual is easier to access as
compared to BIM and CAD software which requires technical
expertise.

Manual Measurement
✗ CONSTRAINTS
Time consuming for tracking and monitoring
An amount of time is required for checking and referring the
resources of the project in manual measurement.
Limited information
Manual measurement does not provide other vital
information such as real-time data, maintenance planning
and space planning.
