28. PART B

29. PREPARATION/BRIEFING
STAGE

30. ADVANTAGES OF USING BIM
Provide better global vision of projects.
• BIM makes it possible for the clients, neighbourhood residents, future occupants and
also site workers to visualize future buildings much more concretely than on plans
have a clearer insight into the project.

31. ADVANTAGES OF USING BIM
Better outcomes through collaboration.
• Project data are more easily accessible through diverse BIM software which makes
sharing and control of project information more efficient.
• In other words,BIM gathers project members to decide and address onsite related
problems more effectively.

32. ADVANTAGES OF USING CAD
MEASUREMENT
Reduced storage space required.
• Previously,paper drawings would have required whole rooms to store the drawings
a building.
• Now this information can be stored on a single disk.

33. ADVANTAGES OF USING CAD
MEASUREMENT
Designer can use CAD to make virtual reality simulations of the layout of their
buildings.
• This means that the client can have a “look around” the building before it is built and
changes can be made at the early stage.
• This results in a faster design of the building and a higher quality end product.

34. ADVANTAGES OF USING MANUAL
MEASUREMENT
Cost Effective
• It is the cheapest method among the BIM and CAD Measurement.
• As it does not require to purchase any software which is costly.

35. ADVANTAGES OF USING MANUAL
MEASUREMENT
No addition investment of training program
• As every quantity surveyors know how how to do measurement manually which
previously learn in respective universities but they might not know how to use
to do measurement so additional training is required for them to master the
• Thus,hiring cost of professional to teach them is required.

36. CONSTRAINTS OF USING BIM
Cost of software.
• BIM software requires a substantial investment in new technology. The advantages
usually make the investment worthwhile, but only if the software is used to its full
capacity..
• The expense is an inhibition to smaller contractors who can’t afford it.

37. CONSTRAINTS OF USING BIM
Incompatibility with partners.
• BIM is not yet universally used among construction professions.
• There is always the possibility that one of your partners or subcontractors may not
use BIM and may not be able to use your models.

38. CONSTRAINTS OF USING BIM
Lack of experts.
• Limited numbers of experts working in the field due to the newness of software.
• So it may require an additional investment in training and education.

39. CONSTRAINT OF USING CAD
MEASUREMENT
• The initial costs of buying computer systems are always quite high.
• When initially starting, factors like hardware, software and location may be required
which translates into high expenses

40. CONSTRAINT OF USING CAD
MEASUREMENT
Information can be instantly lost or corrupted if a computer problem occurs and there
are no backups.
• The software does not have a backup system.
• Users needs to save their works each 30 minute constantly so that data will not lost.

41. CONSTRAINT OF USING MANUAL
MEASUREMENT
Risk of errors
• The risk of errors is greater, especially in repetitive work like payroll calculation.
Quality of output
• Quality of output is less consistent and often not well-designed. At worst, hand
records may be illegible and so completely useless.
• Poorly presented information may fail to communicate key points.

42. CONSTRAINT OF MANUAL
MEASUREMENT
Alterations.
• It is difficult to make corrections. If a manual documents contains errors or need
updating it is often necessary to recreate the whole documents from scratch, rather
than just a new version with the relevant details changed.

43. DESIGN STAGE

44. BIM CAD MANUAL MEASUREMENT
Strength 1. Visualize future
buildings
2. Combines аll dаtа linked
to аrchitecture,
infrаstructures and
technical building trаdes
and аutomatically
recovers quаntities
1. Layers (transparent
overlay) can be named
to help track content,
and lock layers
2. CAD systems also able
to perform modelling
cutaway drawings
1. Able to quickly create
different alternatives,
saving effort, time and
costs yet practical to our
customers.
2. One can still continue
their work when the
software happens to
have some problem.
Limitations 1. Does not provide
systems such as
structural and MEP
details.
2. The coordination
process results are not
valuable that much
because the only 3D
model exist is the
Architectural.
1. Improper use of blocks
and layers make
updating and
modification of the
drawings more difficult.
2. Drawings unable to
incorporate information
about the nature of
materials.
1.Manually creating 3D
model will be time
consuming and unrealistic.
2.With manual drafting, all
the objects drawn must be
of correct size and
alignment.

48. Construction Stage
[ ADVANTAGES AND CONSTRAINTS ]
• Building Information Model (BIM)
• CAD Measurement
• Manual Measurement

49. Building Information Model (BIM)- [ ADVANTAGES ]
• Avoid Conflict
BIM toolset helps mechanize clash detection of elements.
By demonstrating all of these things first, clashes are exposed early, and costly on-site
clashes can decrease. BIM also ensures a perfect fit of elements that are manufactured off-
site, allowing these components to be easily fastened into place rather than created on-
site. An Australian analysis found that BIM’s ability to detect and avoid conflicts prior to
construction reduces unbudgeted
construction changes by 40%.
• Prefabricated materials and
pre-assembled components
BIM’s cultured modelling capabilities also allow contractors
to make much greater use of prefabricated materials and
pre-assembled components, which have well-recieved
productivity and high quality .
• Reduce Mistake
65% of builders reporting and agree with that BIM technology effectively reduces rework,
cost overruns and missed out schedules during construction.

50. Building Information Model (BIM)-[ DISADVANTAGES ]
• Communication
One important problem when implementing BIM as an essential part of your project is the
cooperation and access to the model by everyone involved during the construction stages.
Communication between the parties will breakdown because without a standard form,
contractual documents and code practices of BIM, there might be some clashes between
them.
• Transition from Drafting to Modeling
These will be the challenge to require a higher-level skilled design drafter who has an
understanding of the project and the detail of every material used to make sure that all the
components are coordinated with the other design professionals like engineer or architect
and that site problem are decreases to a minimum.

51. CAD Measurement-[ ADVANTAGES ]
• Measurement is more accurate as CAD drawings are produces in actual size and error in
quantities due to usage of wrong scale is eliminated.
• Easy editing of quantities measured because duo to the similar with any other software,
CAD contained function like block, entity area, copy, paste, delete, undo that facilitate the
editing process.
• Increase the speed in measurement quantities because CAD produced the semi-
automatic ability to measure the quantities.
• Improve communication process. Due to the easier understanding of the design and
measurement. This can reduce the misinterpretations and uncertainty in reading plans.
CAD can generate clear perspective views of a structure to provide accurate information
and makes the construction efficient.

52. CAD Measurement-[ DISADVANTAGES ]
• Objects must be “Polyline”
If the object is not drawn using “polyline”, CAD can only measure the length of the line but
not the area. This will affect the purpose of using CAD to measure as the QS have to refer
back to the manual measurement of obtaining length and width to calculate the area of the
element.
• CAD limited to measure quantities only.
To generate BQ, the quantities have to transfer manually to another software that can
generate quantities in a BQ format.
• Not able to measure quantities that are require three dimensions like volume, only can
measure two-dimensional.

53. Manual Measurement - [ ADVANTAGES ]
• Save cost
Manual measurement is the cheapest method compare with using software. Software is
expensive and costly to purchase due to the convenience of the QS.
• Skills is unlimited
Every QS know how to exposed to manual measurement, especially the fresh graduate QS. So.
Easily to hire and also no training required.
Manual Measurement - [ DISADVANTAGES ]
• Time Consuming
Variations will happen sometimes. So, changes have to be made. Manual measurement
consumed a lot time and indirectly, this will cause extension of time.
• Accurate of the quantities
Software can identify the error easily compare to manual measurement. Manual measurement
will cause error because people will make mistakes sometimes.
