BIM
Building Information Modeling
The new technology that reduces the cost and improves the quality of building construction

The term BIM (Building Information Modeling) denotes the modern software
technology regarding construction of buildings.
The underlying concept of this technology, which has emerged during the last
decade, is extremely simple. According to this concept, the building can be
described by its physical components/objects (walls, columns, beams, etc. ).
These objects, instead of being stored as drawings, are actually stored in an
intelligent database.
By retrieving the physical components of the building from the database, the
BIM software, is able to:
Create the three-dimensional model and all the drawings that can be derived
from it (floor plans, elevations, sections, perspective views).
Calculate the precise quantities of materials and cost items in general
needed for the building construction, thus estimating its anticipated cost.
Create any computational model (bioclimatic, static-dynamic etc.).
The database structure, namely the concepts that underlie the building
construction, is defined in the global IFC format (International Foundation
Classes). IFC format is being developed within the framework of cooperation
of software and building industry companies.
THE EXISTING CAD SOFTWARE TECHNOLOGY
The software companies, have
developed over the last 3 decades
the drawing-centered CAD
applications (Computer Aided Design
or Drafting), representing the
traditional approach of describing a
building with multiple drawings (floor
plans, elevations, sections,
perspective views).
The underlying logic of CAD technology
has three major disadvantages:
1. A lot of work required since many
drawings should be prepared in order to
describe the building.
2. Quantity take-offs needed to calculate
the total cost are carried out, based on
these drawings, almost manually. This
task requires a great amount of time
and specialized personnel, while,
eventually, significant uncertainties will
arise due to human deficiencies.
3. For any modification to be applied on
the building, both (1) and (2) steps
should be performed all over again.
THE EXISTING CAD SOFTWARE TECHNOLOGY
1. Decreases the design time in the
range of 70% and 95%.
3. Ensures the accurate transfer, in
real time, of huge volumes of
construction data between the
building designers, contractors
and industries involved at all
construction phases.
2. Increases dramatically the
accuracy/reliability of quantity
take-offs.
BIM COMPARED TO
EXISTING CAD TECHNOLOGY
BIM SOFTWARE TECHNOLOGY APPLIED ON
R/C STRUCTURAL FRAMES
The structural frame of R/C
buildings also follows the general
rules of BIM technology
mentioned above.
However, two decisive
particularities are not met in
other parts of a building that do
not comprise its structural frame:
BIM SOFTWARE TECHNOLOGY APPLIED ON
R/C STRUCTURAL FRAMES
1. The design of the structural frame is extremely complicated, especially
regarding the computational part.
BIM SOFTWARE TECHNOLOGY APPLIED ON
R/C STRUCTURAL FRAMES
2. The need to determine a huge number of rebars
(e.g. tens of thousands pieces in a middle scale multistory building).
CURRENT STATE OF BIM TECHNOLOGY
Mr. Apostolos Konstantinidis, structural engineer, inventor and author, has established
himself as a pioneer in both structural software and R/C construction markets. He has
been dealing with BIM technology since 1982, long before this technology has even been
given the name BIM. Today, BIM technology is integrated in his holoBIM application.
holoBIM is written in C++, while the Virtual Reality environment in OpenGL.
