Limitation of 2D Drawing (1/2)Limitation of 2D Drawing (1/2)
The reader must interpret 2D Drawings and recreate
design intend b their knowledge and experience.
These drawings can run into hundreds of separate
documents, which make it very difficult to gain an
overview of operations resulting in inconsistencies
(Stebbins, 2007).
CAD documents exclude information required for
evaluating a design and monitoring construction
activities (Oskouie et al., 2010).
.

Limitation of 2D Drawing (2/2)Limitation of 2D Drawing (2/2)
Bids and contract documents, bill of materials
(BOM), time frame specifications, costs, labelling as
well as installing and maintaining guides are also
not included.
According to Knight (2008), the growing
complexities of design models threaten to makecomplexities of design models threaten to make
CAD drawings insufficient and redundant.

Building Information ModelingBuilding Information Modeling
B ildi I f ti M d li (BIM) hi h h b d fi dBuilding Information Modeling (BIM) which has been defined
as “a digital representation or visualisation of physical and
functional characteristics of a facility. In addition BIM serves
as a shared knowledge resource for information about a
facility forming a reliable basis for decisions during its life-
cycle from inception onward” (Eastman and Tiecholz, 2008).y p ( , )
From this definition it is evident that BIM is a multipurpose
tool facilitating design and development, data management
and planning functions.and planning functions.
The drivers for BIM are the exigencies of a fast expanding,
increasingly complex construction industry, the need for more
d i i d di i ll k h ld dproductivity and co-ordination amongst all stakeholders and
reducing variance between customer expectation and final
product (Tolman, 2008).

Maturity Level of BIMMaturity Level of BIM
A maturity model was developed by the UK Department of Business Innovations
and Skills (BIS). BIS defined the levels from 0 through 3. A majority of the market is
still working with Level 1 processes, and the best in class are experiencing
significant benefits in Level 2.

Values of BIM on DesignValues of BIM on Design
BIM i t i t 2D d 3D d iBIM is a great improvement over 2D and 3D drawings
since it enables designers to view the building from all
angles (Bentley, 2009). This enables identification ofg ( y, )
any errors at an early stage which can then be
corrected avoiding costly rework.
O f h f i li i f BIM i i i fOne of the functionalities of BIM is incorporation of
parametric design elements. Changes, additions or
editions in any one parameter results in simultaneouseditions in any one parameter results in simultaneous
reconfiguration of all other elements involved in the
design including sectional and elevation dimensions, raw
material requirements cost of production andmaterial requirements, cost of production and
construction schedules and timelines (Emery, 2008)

BIM allows visualization of form with some
resemblance to realities (Manning and Messner,
2008). This allows evaluation of both aesthetic and
functional features. Thus even non – technical
stakeholders can easily understand these models.

4D BIM = 3D + Schedule (Time)
The construction of the 4D models enables the various participants
(from architects, designers, contractors to owners) of a
construction project, to visualize the entire duration of a series of
events and display the progress of construction activities through
the life time of the project. This BIM-centric approach towardsp j pp

5D BIM = 3D + schedule (time) + cost
which refers to the intelligent linking of individual 3D CAD components or
assemblies with schedule (time) constraint and cost-related information.
Th f h 5D i i d d f h ddi i f f hThe use of the term 5D is intended to refer to the addition of fourth
dimension: time and fifth dimension: cost to the 3D model, i.e. 5D is 3D +
schedule (time) + cost.
The construction of the 5D models enables the various participants ( from
architects, designers, contractors to owners) of any construction project,
to visualize the progress of construction activities and its related costs
Mover time. This BIM-centric project management technique has a potential
to vastly improves the project management and delivery of construction
project of any size and complexity.

Value of BIM to the industryValue of BIM to the industry

BIM i t it f h i d i f tiBIM is a one stop repository for such varied information
as supplier data, manufacturer information, costing,
dimensional data and component specifications.p p
Consolidation of data allows the project managers to
provide clients with value added services. These include
information on lighting heat power usage furnitureinformation on lighting, heat, power usage, furniture
and post occupancy requirements (Howard, 2008).
Liston and Fischer (2010) believe that data attached toListon and Fischer (2010) believe that data attached to
individual components increases accuracy of pricing
and bidding. Construction schedules can be optimized in
the face of constant changes in availability andthe face of constant changes in availability and
delivery of raw materials and design changes.

40% elimination of unbudgeted change. Industry average 10-
20% on a project. Thus 4-8% of overall cost
I i i hi / 3%Improve cost estimate accuracy within +/-3%
Less than 1% cost growth
Bids within +/- 2.5%
60% less RFI’s
80% reduction in time to generate cost estimate
ROI of 3D model: 5X-10X, saved 10% of contract sum through
clash detection (based on 2D ->3D project)
7% schedule reduction
